5 lies of smartphone companies that will open your eyes

5 lies of smartphone companies that will make you angry
5 lies of smartphone companies that will make you angry

As soon as we get a new smartphone, its updated version comes only after a few months and in that new version, by changing the design a little bit and updating it in a very minimal way in its hardware and camera, in this way It is presented that now your old smartphone has become completely useless in front of that new phone and by doing this you are encouraged to buy a new smartphone. While many times companies also do false advertisement.

Fake advertising of their products by smartphone companies

Recently, Realme's flagship smartphone GT 5G was banned by Antutu for 3 months due to showing fake benchmark scores and in a launch event of his second smartphone Narzo 30A, the use of iPhone during the demo of the game has exposed the company's fake advertising.

Not only that one company did this, but also smartphone companies like Nokia, Samsung, Huawei and Apple make false advertisements and show their products exaggeratedly so that they can show their company's smartphones better than other companies and with which they can force people to buy their smartphones.

5 Things that Smartphone Companies Promote Wrongly

While there are a lot of things that companies hide from their customers, but we talk about the 5 main things about which the smartphone company often promotes falsely:

1. Smartphone camera

So the first among them come to the smartphone camera about which the most confusion is spread, companies show such photos at the time of the launch of the smartphone and promote those photos on TV that, As such, the camera of their smartphone is also better than DSLR.

they also show the camera of her 20-30 thousand smartphone is better than the camera of the iPhone or Pixel smartphone, but the truth is that most of it is a lie and this photos shown in the camera sample during publicity is clicked by a DSLR camera and it is taken by a professional photographer in a perfect environment so that it looks good.

The company does not show the RAW photos taken from the camera of its smartphone, but rather edit it with the help of heavy software and make it perfect by applying a lot of filters and then show it to us. At the same time, even if you bought that smartphone, it will take you years, but you will not be able to take a single photo.

Nokia Pureview faked ad
Nokia Pureview faked ad (Image credit:

By the way, this trend has started from the beginning in which advertisements of smartphones like Nokia Lumia 920 to Hawaii Nova 3, DSLR or any other smartphone's camera photos were promoted by telling these smartphones but in some way people caught it.

2. Smartphone Processor and its Capability

Now the second biggest lie is told about the smartphone's processor and its capability. So as soon as the new processor arrives in the market, almost all the companies launch their smartphone with it, but they highlight it so much that as before the processor was very slow and this latest processor will work at the speed of light.

But is it really that new processors are so fast, it is not that, but whatever new processor is launched, it is only a few milliseconds faster than the old processor, which we can not notice. Old processors can perform all the tasks very fast like new processors and you will not understand any difference whether playing a game or running an app.

Yes, this difference will definitely make sense when you compare a Snapdragon 600 Series with a 700 Series or a Snapdragon 700 Series with an 800 Series processor because their architecture is different. But if you compare between 2 or 3 generations in the same series such as Snapdragon 845, 855 or 865, then you will not be able to understand the difference on the basis of performance, no matter how much their bench mark difference.

3. Smartphone display

The third most inaccurate advertising item in the same smartphone is its display, which includes unknown technologies such as Retina Display, Super AMOLED, LCD, OLED etc. In this, by giving a notch in the centre or in the corner or by curving the display a bit, it is so hyped that with this display, this smartphone will look absolutely cool and if we look at it, we will see another world.

Although the display's PPI and technology like hdr10 or XDR make the quality of the display better, but the type of the display does not affect the picture quality much and not much at all for which you buy a completely new smartphone.

In order to make the display better, even companies show the display of the smartphone in a more colourful and curved shape in their advertisements. Xiaomi did the same in the advertisement of its smartphone some time ago, due to which that smartphone started to look like a different model.

4. Removing the headphone jack from the smartphone

The fourth lie of companies is to remove the headphone jack to make more space in the smartphone. In 2017, a company like Apple removed the headphone jack from its smartphone, saying that it would increase the space for equipment inside it, after which many more companies started doing so.

So what happens is that from the beginning all the companies have been providing earphones with smartphones and have connected their money with the MRP of the phone, but in order to earn more profit, the company thought not to give the ear phone but it was so Not only was he happy with this, he also removed the headphone jack from the smartphone in order to sell his wireless air birds and earphones, so that no other company's wired earphones could be installed in them.

What did companies give an excuse for that would save space, while after all these years, many flagship smartphones are coming with a 3.5mm jack and today they are already using much better and new technologies. Also, despite the headphone jack, many of these smartphones are also waterproof.

5. Smartphone out of stock in online flash sale

The fifth lie is about the smartphone being out of stock in flash sales. Have you ever known in sales that how many smartphone units were going to be sold in this sale? and how many of them were sold, not because this company will never tell you.

See if there is a small company and its product ends, then it makes sense, but the top brand smartphones are sold in flash sales, this company produces millions of smartphone units at a time, But so many smartphone units are sold in such flash sales not in minutes but in seconds. So know this is completely fraud and you are fooled.

This company does this to create hype of the product and forces you to wait for a long time by closing the site in a few seconds

All these things don't end

By the way, many such things like RAM, fast charger, system update, non-removal battery, the smartphone companies are tempting you to buy new smartphones only by entangling you in the number game.

By the way, if you are going from a cheap mid-range smartphone to a high-end smartphone and upgrading to it, then it is fine, because in it you will get a completely new experience, But if you already have a high-end flagship smartphone and a new model has come, then you should definitely avoid buying it.

Because even if you take 40-50 thousand and take a new mobile due to just one or two features, there will be no value add in your life, rather in a few days it will also become old. So as long as your old smartphone is working and all your work is being done in it, then it is sensible to work with it or else the smartphone company wants you to take their new phone every year so that their earnings will increase.

How to disable the power button on the lock screen of a smartphone?

The thief will not be able to switch off your smartphone.
The thief will not be able to switch off your smartphone.

If you lose your phone, you can easily locate it by going to Google Find My App or computer browser through the security option of your Google Account. But the biggest problem is when the mobile is stolen, the thief switches off and keeps it in his pocket as soon as he finds it, due to which your mobile is not locked.

So that no other person can switch off your smartphone, you should disable the power button of your smartphone on the lock screen, so that no one will be able to switch off your smartphone without opening the lock.

Advantages of disable the power button of the smartphone on the lock screen

I recount an incident that happened to me a few years ago, at that time I was travelling in the bus at night and the bus stopped for a while for breakfast in a hotel, so as soon as I had breakfast I getting back into the bus and Reached the seat, I realized that I do not have my smartphone in my pocket.

So without delay, I immediately stopped the bus and started looking for my phone and asked another person to call my phone and as soon as he called my number, my phone started ringing and I got my phone The ringtone began to be heard inside the bus.

Since my phone had a problem with the power button and it did not work properly, the thief was not able to switch off the phone immediately and I was able to find my phone. Yes, I do not believe in violence, so I did not beat the thief, but I got my smartphone due to a malfunction of the phone, so I was very happy.

How to disable the power button of your smartphone?

By the way, you do not have to deform your smartphone power button for this, you can do this by going to the settings of your smartphone so that if someone finds your smartphone, they cannot switch it off immediately and you got some time to find the smartphone.

By the way, this method is currently only for Android 10 and Android 11 users and this option will not be available in smartphones with earlier Android versions. So let's know how to do it:

Searching for the side key or power button in the smartphone settings

First of all, you have to go to the settings of your smartphone and search for the power button or the side key. After that, going to that setting, in the function of the power button, you have to select the voice assistant instead of the power menu.

By the way, I show this process step by step for smartphones with stock Android and custom UI.

Disabling the power button in a stock Android smartphone

You can disable the power button in a smartphone-like Google Pixel, OnePlus, Nokia, Motorola, stock Android or similar UI stock smartphone like this:

Buttons & Gesture Options in Settings

Select the function inside the 'Press and hold the power buttons' option.

3. Now you will have the option to select the function, where you select the voice assistant instead of the power menu.

By doing this, pressing the power button of your smartphone will open the Google Assistant instead of the Power menu. To switch off or restart the mobile, you can go to the power option on the notification panel, but for this, you have to open the lock of your smartphone first.

Disable the power button in a smartphone with custom UI

Since every smartphone I have this setting is different, I will tell you the settings of one of the smartphones with custom UI, Samsung's One UI smartphone:

Advanced Feature Option in Samsung Smartphone Settings

All UFS memory versions details and how eUFS memory is better than other portable storage?

UFS & eUFS memory
UFS & eUFS memory

The main objective of UFS storage is to replace the SD card and eMMC storage in ultra-portable PCs, smartphones, tablets and embedded devices and to provide manifold higher data transfer speeds, more storage and security.

Along with this, the battery of the device has to be saved by reducing the power consumed by the memory. By the way, what is UFS memory and how is it better than other portable storage, so let's know it.

What is managed memory and how is it used in portable devices?

UFS, MMC and SD cards are a kind of managed memory, that is, you can save or delete any particular data from these memories such as a picture, but if we delete one of the particular data from unmanaged memory then the entire Memory is formatted.

So just as hard drives and solid-state drives in computers and laptops called HDD and SDD in short and it is managed permanent memory, similarly UFS, MMC and SD memory come for smartphones, smartwatches etc.

The same non-volatile memory, such as UFS and MMC, is embedded inside the gadgets, soldered into its circuit, making it act like a ROM in the device and is embedded in the circuit board of the device, The name changes from UFS and MMC to eUFS and eMMC.

MMC memory usage

MMC memory
MMC memory (Image source:

MMC, ie multimedia card, was unveiled in 1997, which is still used in cameras in external solid-state storage rooms and most computers have a port for this.

It is still used as a ROM in the embedded form in cheap smartphones and gadgets, in which eMMC storage is used in smartphones coming with Snapdragon 400 and 600 series, Snapdragon 810, 820 and most of MediaTek processors.

Features of eMMC memory

The eMMC works on a half-duplex protocol, meaning that it can have only one operation at a time and cannot have read and write simultaneously, and it operates in a single direction.

eMMC consumes up to 3.3 volts of power and can transfer data at a maximum speed of 250 mb/s read and 125 mb/s write speed, and it cannot have more than 11000 input/output operations in a second. All these specifications are of the latest eMMC 5.1 that launched in 2015.

Why UFS Memory Needed?

UFS technology was worked on to update the eMMC memory and to achieve higher data transfer speeds and IOPS capability, which works on full-duplex protocol and is capable of bi-directional operation, which makes it simultaneous Can perform read/write operations at the same time.

UFS memory technology is also used in two ways, the first as a memory card containing UFS version 1.0, 1.1 and 2.0 and the second embedded memory which is the eUFS version which contains 1.0, 1.1, 2.0, 2.1, 3.0 and its latest version 3.1.

By the way, before we know the version of UFS memory, we first get to know about Sequential and Random read/write speed and single bandwidth and dual bandwidth, because these terms will be used every time.

Sequential and Random Read/write Speed

Sequential Read/Write Speed is the speed of transferring a large file or folder from one place to another. Random read/write speed is the ability to handle the number of input/output operations inside the memory in 1 second and is used when installing or running a software or application.

Single lane bandwidth and dual lane bandwidth

Bandwidth is the maximum theoretical data transfer speed of memory, the same single-channel memory transfers data from only one data channel, while dual-channel memory transfers data through 2 channels. That is, if a memory transfers 64-bit data from one channel, it will transfer 128-bit data through 2 channels.

You can understand it in such a way that if you send your goods in 2 trucks instead of one truck, then you will be able to supply double the goods in one go. Similarly, double lane bandwidth will transfer data at twice the speed of single-lane bandwidth.

UFS Memory Versions

eUFS 3.1 (image source:
eUFS 3.1 (image source:

UFS memory is being used as embedded in portable gadgets, also known as eUFS and they have 6 versions so far, which are as follows:

UFS 1.0

So the first of these came in 2011 in eUFS 1.0, also known as UFS 1.0, and it came in 16, 32 and 64 GB storage options, with a sequential reading speed of 250 mb/s and writing speed of 75 mb/s had the same random reading speed up to 10000 IOPS and writing speed up to 2500 IOPS.

UFS 1.1

Just next year of UFS version 1.0, its updated version UFS 1.1 came with some improvements but both these versions are not used in any smartphone yet, it came with a single lane with a maximum bandwidth of 300 mb/s.

UFS 2.0

In 2013, UFS 2.0 was launched which was double lane memory with a single-lane bandwidth speed of 600 mb/s and double lane bandwidth speed of 1200 Mbps. Compared to UFS version 1.1, the addition of link bandwidth, security features extension and additional power-saving features were added.

It was first used commercially by Samsung in its Galaxy S6 smartphone in 2015. That is, this technology came just 6 years ago and there are continuous improvements in it.

UFS 2.1

Subsequently, in 2016, security was promoted in UFS version 2.0 itself and added inclined cryptographic operations, and introduced as UFS version 2.1 and UFS 2.1 is still used in most mid-range smartphones.

UFS 3.0

In 2018, USS Technology underwent major improvement with version 3.0 and its speed increased manifold. In UFS 3.0, the sequential read speed reached 2.1 Gb/s and write speed 410 mb/s, while its application and gaming handling reached a random read speed of 68000 IOPS and a random write speed of 63000 IOPS.

UFS 3.1

With a single lane bandwidth of 1450 mb/s, the bandwidth of both its lanes together was increased to 2.9 Gb/s, due to which the gaming performance of the gadgets became very good.

The latest version 3.1 of UFS came in the year 2020, in which the bandwidth and number of lane remained the same as its old version 3.0 but it added a right booster which increased its right speed.

Performance throttling notifications have also been added to this so that it informs the host about the performance decreasing in the event of over temperature, and in this version also the ideal mode has been added.

The maximum capacity of UFS storage is up to 16 TB and it consumes power between 0.2 volts to 0.4 volts, meaning that UFS storage is superior in comparison to eMMC storage in every respect.

Use of UFS memory in smartphones

Talking about the use of UFS memory in smartphones, UFS version 2.0 is compatible with the smartphones that come with Snapdragon 820, 821, kirin 950, 955 and Samsung's Exynos 7420 processors and have been implemented with them.

UFS 2.1 were implemented with Snapdragon processors ranging between 700 Series and Snapdragon 835 to 850, Kirin 960,970 and Exynos 9609, 9610, 9611, 9810 and 990 and MediaTek G90 processors.

In addition to the UFS version 3.0 Snapdragon 855 and 865 processors, processors with Exynos 9820/9825 and Kirin 990 have been implemented and are also supported by Snapdragon's older 835 and 845 processors.

"The first smartphones to come with UFS 3.0 were the OnePlus 7 and OnePlus 7 Pro, and this smartphone was first launched with the Snapdragon 855."

Talking about the latest UFS 3.1, it has been implemented with Snapdragon 865 and 888 and will come with future processors.

UFS Flash Storage

Apart from eUFS, there are also UFS memory cards that Samsung announced in 2016 that support single bandwidth. The maximum bandwidth speed of UFS memory card versions 1.0 and 1.1 is 600 mb/s and the maximum bandwidth speed of version 2.0 that introduced in 2018 is 1.2 Gb/s.

The UFS memory card is not supported in the current smartphone, but maybe we will see it soon in Samsung's latest flagship smartphone.

While the esports have been included in the Asian Games to be held in Guangzhou city of China in 2022, the Olympic Council of Asia is also a partner of which ESFI of India is also a member.

As of now, esport is getting the status of an official sport and its popularity is also increasing very fast and along with it there will be many more technical advancements in the future, so it will be promoted as a sport soon and with it It will also be included in extra circular activities in schools along with other sports.

That is, in future, children will also be taught to play video games in school and they will be trained for esport tournament.

Start of esport in India

While most people in India have done esport's first experience with pubg mobile and people also liked it a lot, Pubg has also organized many esport tournaments.

But even after the pub is banned, you have availabe a lot of multiplayer games like Free fire, call of duty, League of legends, Dota 2, Overwatch, valorent, Heros of storm, fortnight, Counter strike etc. which you can play And can participate in esport tournaments through these games.

Since esport tournaments are genrally played with the team itself, these tournaments are currently only involving multiplayer games, in which you can participate in these tournaments by forming a team with your friends.

By the way, apart from these tournaments, you can also create your own gaming channel on YouTube and YouTube gaming channels like Mortal and Dynamo in India are earning in millions and their net income has also reached crores.

So if you are also fond of games, then you too can make a career in it, yes, like the rest of the field, you will not get anything easily in it and you will have to work very hard but these efforts are very fun.

How digital health will revolutionize our future?

One person one medical record
One person one medical record

As of now, you must have known about two types of health care system, private health care and public health care system, but now digital health will also be common in the coming times. Since health is a very personalized matter and every individual person has different treatment according to him/her, in the future every person will be treated accurately with the help of digital health.

I am talking to you about digital health and how it will make healthcare better and how it will help in medical treatment in future.

How will digital health work?

Think if you go to the doctor and you tell him the ID of your medical history, then he will be able to see the entire medical history of you and your family on his computer and how is your daily activity, whether your heartbeat is normal or not When your body temperature is high, it will be able to see all the things.

He will know all the things that have happened to you in your medical history and what kind of medicine happened to you at that time and what kind of vaccine you got in your childhood. So it will be that with the help of this data, the doctor will catch your disease quickly and will be able to get the right treatment.

Since the medical history of any person is very important for its treatment and on the basis of this, different medicines can be made according to each individual human being, so that you will get healthy very quickly.

What is digital health?

Digital Health will provide you with personalized medicine and treatment with the help of Mobile Health, Health Information Technology, Telehealth, Telemedicine etc. by connecting your health, health care, living society etc. with digital technology.

In the future, Digital Health will work on the basis of One Person, One Health Record, in which each individual will have a separate record that will be linked to the National Health Care System and this data will also be used in clinical research so that for you The medicine can be made in an effective way.

So it happens that when your health is bad then you go to the doctor and the finished doctor does not know about your past medical records and body fluidity or immunity, so he writes a lot of tests and because of those tests According to the disease which the doctor understands, he gives you medicine.

The same drug affects every person in different ways and not all people have the same effect, this method also takes a lot of time and money.

What does one person one medical record mean

Right now we cannot even think about personalized medicine, so in the future, the adoption of digital health is being started in which a person will have a record from birth to death and will have complete data of his health.

In which, when he got vaccinated, when he became ill and what kind of medicine affected him, etc., he is not allergic to anything or whether there is any genetic disease in his family that he may have in the future, etc. Information will be in a digital record.

Under Digital Health, any hospital where you will get your treatment, that hospital will continue to enter your medical data and will update the treatment of the present patient therein. The same data will also be updated by your smartphone or worn smartwatch, and by how much you slept and how much exercise you have done, it will continue to feed you into your medical history.

All this process A.I. It will be best, due to which if there is some unusual activity in your body, such as being in constant stress, you will be monitored by detecting high pulse and you will be alert before you have a heart attack, so that If you become aware and can consult a doctor on time. Because your entire medical history will be in one place, the doctor will not take much time and according to you will start the personalized treatment.

How was the result of Digital Health Implementation Test

The introduction of digital health was seen in some places in Africa, where the child's health record was stored in one place and when the child was to be vaccinated, his parents were told by messaging and along with it Their sleep and BPM were continuously monitored through smart bands.

In case of any problem, his parents can consult the doctor through video call and get the right knowledge and the doctor can also give them the right prescription with the help of that health record. So, due to all these processes, the parents had reduced their headache and they had to reduce the clutter too, they also saved their money.

So like this, under digital health, you will be helped in exercising, getting good sleep and reducing stress etc. and a digital record will be kept of all your medical history, with the help of which personalized medicine will be made for you according to your immunity and body. According to this digital medical record, your medical treatment will also be done.

How the Internet of Things (iot) is going to make our future awesome

Our future is going to be so awesome
Our future is going to be so awesome

The Internet has connected all the people of the world, so through this, we can send many information files, photos and videos to other people sitting at home and can also do live conversions with them through video calls.

But the internet which was till now only for humans, now in future it will also be connected to our things and will improve our lifestyle further. We are talking about the Internet of Things (iot) and because of this how our future is going great.

How did the internet change our lives

It has been almost 26 years since the Internet came to our country and because of this our lifestyle communication and business has improved a lot, there are some bad effects like social media addition or over entertainment, but we all Except, we have become very smart due to the Internet and with the help of this, we can control some of our home appliances which are connected to the Internet.

I am talking about IoT ie Internet of Things in which many devices in your home will observe the situation itself and do the act of recording the situation and take your permission in those situations where it is a matter of your choice.

What does the Internet of Things (iot) do?

Suppose you have gone outside the house and you have forgotten to lock your house and at the same time forget to turn off the geyser, AC, light, TV etc. in the house, then your house itself will sens it that in your house No one is there and will turn everything off on its own and send notifications to your smartphone.


Whenever you need it, you will turn everything on again from the smartphone and will be able to open the lock of the house from your smartphone.

Now we come to another scenario in which if you are at home and you fall asleep watching TV, then your house will understand with the help of a smart band or camera worn by you and turn off the TV and the unnecessary lights glowing in the house Will also be closed. The temperature of your room will also be maintained according to you, due to which you will not have to reduce or increase the temperature of the AC after getting up from sleep.

Life Saving Benefits of the Internet of Things (iot)

Talk about life-saving benefits of iot, then suppose it is 3:00 in the night and your health is suddenly deteriorating and meanwhile, you have a heart attack and iot in your house, then your wearing smart band / Smart Watch, or with the help of any other sensor, your house will detect the unusual activity happening in your heartbeat and body and send all these details to the nearby hospital.

Along with this, with the help of iot, your home will alert the hospital on its own and will also send the news to your well-wishers, so that the hospitalists will send an ambulance to your home without delaying and it can save your life.

The same technology will be implemented in all the things in your house such as smart band, camera, etc. And if a thief enters your house or your car is accidentally hit or there is a fire in your house, then this device Being connected to iot, we will send the news to the police station, fire brigade, ambulance etc. and all these things will be connected to the server room of the area which will keep an eye on the unusual activity happening in the area.

Future of iot

iot technology has now started to grow and it is also very easy to implement, just all devices and home appliances will have an electronic chip and some sensors, with the help of which these devices will share the information and share the information with the rest of the equipment at home and will take action according to that situation.

By the way, many devices have been started implementing this smart technology such as smart refrigerators or air conditioners, and they themselves inform the company when there is leakage or shortage of gas in the compressor or upon the requirement of servicing and by which you are contacted for servicing the customer care of that company.

For this, you just have to connect these devices to your home WiFi and also connect to your smartphone, by which it diagnoses the problem by itself and tells you and you can control them from your mobile as well.

Due to the same internet-of-things, you will also have control over the rest of the house such as inverters, geysers, lights, fans etc. and all these things will work on your single gesture or voice. Because of this, our future is going to be very amazing and all these things will not be less than any superpower. These things will probably be very common in the coming 10-12 years.

Why high-speed memory card required in high-resolution video recording?

Doesn't video clear in high resolution recording?
Doesn't video clear in high resolution recording?

Often you have seen your friends happy at some point that the 32GB memory card you bought for ₹ 650, they got the same company memory card for just ₹ 400. But whenever he shoots or plays a high resolution or 4K video using that memory card, the quality of that video is not correct and editing and processing of that video also takes time.

So let us now talk about Secure digital ie SD card and whether it also affects the video quality of your camera, so let us know this.

What is flash memory?

Flash memory is the memory that stores data inside itself and does not require any power source for it. So just as laptops and computers have hard disk drives and SSDs in internal memory and use pen drives as external flash memory, similarly mobiles also have an internal memory of SSDs and UFS type and micro SD card can be used as external or Use as flash memory.

By the way, one advantage of flash memory is that it keeps data stored without power supply and you can hide your photo, video or document somewhere in it.

What is the type of Micro SD memory?

Nowadays, this memory card comes in four types according to its storage, the first is Secure Digital SD memory and the second is high-quality SDHC memory which has a maximum capacity of 32GB. The third is the extended capacity ie SDXC memory card and the fourth is ultra capacitance ie SDUC, these two capacities start from 32GB.

Talking about the quality of the memory card, the memory cards are classified in three ways according to the technology used in it according to the speed of their data transfer, and these three types of speed class, UHS speed class and video speed is class.

Speed Class (SC)

The oldest in micro memory is the speed class, which comes by writing 2, 4, 6 or 10 inside the C letter in the memory card and it supports only standard video quality. Among these, the Class 8 type card supports HD video and Class 10 supports recording or playback of full HD video.

UHS Memory Card

A memory card of better type than SD class is ultra high speed ie UHS speed class and its identity is that U comes by writing 1 or 3 in which U1 type memory is compatible for full HD video and U3 type for 4k video.

Video Speed Class

The Video Speed Class is a new type of class, rated just above UHS memory version 5.0, and its mark comes in memory cards by writing V6, V10, V30, V60 and V90. It has V6 HD quality, V10 full HD quality, V30 4K and V60 and V90 compatible for recording 8K video.

speed of the memory card
No Copywrite infringement is intended.

Now talking about the speed of the memory card, the maximum speed of class 2, 4, 6 is 12.5 Mb/sec, while the maximum speed of class 10 memory is 25 Mb/sec and the maximum speed of UHS-I memory is 104 Mb/sec. Also, the maximum speed of UHS-II is 312 Mb/sec. The UHS-3 is characterized by video speed class, which also includes SDUC cards with a maximum speed of 985 Mb/sec.

What does memory card have to do with video quality?

We consider it such that when we turn on the camera for recording, the device streams the data according to the resolution and writes it to the memory card. So as we record full HD video, it will write data at 30 FPS at a speed of 10 mb/sec, which will be handled by memory cards up to class 6 or 8.

video speed class

But if we increase the megapixel or frame of the camera, then this speed rate will be 30 Mb/sec which is not suitable for handling this card at all. And the video that will be recorded and saved in these cards will lag and black spots will come in it and its quality will also get spoiled.

Similarly, on recording 4K video, the camera will stream data at a speed of about 50 mb/sec for which memory below UHS-1 is not sufficient and the same is for video playback. Apart from all this, the memory card also has application performance class A1 and A2 written, which shows how many input/output operations the memory card has the capacity to do at once.

Due to these specifications, the cost of memory card is fixed and due to higher fast speed, the cost of UHS and video class memory is higher as compared to class 10. By the way, where the quality of mobile cameras is getting better nowadays, we need a high-speed memory card in such a situation.

Apart from all this, UFS memory cards have also come into the market but as of now smartphones do not have their compatibility and currently, they can be installed in Samsung's notebook only.

Is a charger really consume electricity without charging the mobile?

How much will the bill be if I keep the charger switch on for the whole month?
How much will the bill be if I keep the charger switch on for the whole month?

We have often heard that if the charger is not used, always turn off its switch and save electricity, but you know that if the charger is not connected to the mobile and still its supply is on, then how much electricity will be consumed in a month?

So let's talk about how much power the charger will consume on standby and how much it will affect our pocket? But before that, we know how the charger works.

How does the charger work?

A mobile charger reduces the 220-volt AC supply of our house to one-and-a-half DC voltages by converting it to DC voltage, which charges our mobile batteries. Normally a mobile charger has 4 main components which are as follows:

  • Step down transformer
  • Rectifier
  • Filter
  • Battery charger controller chip

In which the step-down transformer brings the current to high voltage low voltage and the diode bridge rectifier circuit converts the AC current to DC current because the battery is always charged from DC current.

While there is a third component filter which has a capacitor that acts as a voltage regulator and the last one is the battery charge controller chip which monitors the Soc and Soh of the mobile battery and turns off the charging when the battery is fully charged.

Does the charger consume power even when it is not on mobile charging?

So now comes the question if the charger consumes power even when the mobile battery is not charged, then the answer is 'Yes' because the transformer used in the charger magnetizes its core even at no load, for whom it is Consumes a small amount of power and this is called iron loss.

This magnetizing current is in very tiny amounts, and a very minimal amount of power is consumed in connection to mobile or no-load key. This is only between 0.7% to 2% of the rated output power of the power charger, which depends on the quality of your charger.

By the way, your charger is branded and comes with the mobile, so it will not lose more than 0.7% and it will come with a battery charger controller which will disconnect your charger when your mobile battery is full.

Charger consumption at no load

We talk about how much it is 0.7%, so we take the 15 watt and 30-watt charger that comes in the market nowadays, so the 15-watt charger consumes 0.1-watt power when it is not connected to the mobile and 30-watt charger consumes 0.21 watts of power at no load.

The same thing comes, how much it will be in a month, then a 15-watt charger will consume about 73 watts of power continuously for a month without charging and in a similar situation, a 32-watt charger will consume about 152-watt power in a month.

How much will the bill be when the charger switch is always on?

If we keep the charger plugged on for a year, it will be less than 0.87 units in a 15-watt charger. In India, the price of 1 unit varies between ₹ 3 to ₹ 7, so accordingly you will have to pay rupees in 1 year, which will be a few pennies a month, which is negligible according to our monthly bill.

By the way, a 15-watt charger will charge your mobile for 3 hours daily, then its monthly cost will be around 1.35 units and the same cost will come for keeping the no-load pay charger on for 1.5 consecutive years.

This cost does not matter to you alone, but why does the government ask for the charger to be shut down if it is not used, because if the whole country turns on the charger even when it is not used in the same way, then it will be 2000 in a month Megawatts would be equivalent power, enough to power about 150 homes.

Is Satellite Internet will eliminate the compulsion of mobile towers in the future?

Is there no broadband in your area and net also runs slow in mobile?
Is there no broadband in your area and net also runs slow in mobile?

Are you also one of those people who despite using 4G is running at very slow internet speed due to poor network connectivity, then I am telling you about an option that will soon be available to everyone in the whole world. High speed in the corner will increase internet access.

I am talking about satellite internet, which is still being used by many people, but now there is going to be a huge update, due to which its coverage is in every area of the earth and its internet speed is also going to increase.

By the way, if you think what is special in this mobile tower is also connected to the satellite then why install a separate antenna for it at home, then let's first know how the mobile towers are connected to each other.

Are mobile towers directly connected to the satellite?

If you think that the mobile towers are connected to the satellite then it is wrong, BTS of each mobile tower i.e. Base Tower Station, the round umbrella in the tower called microwave is connected to BSC (Base Station Controller). All these BSCs are connected to the district's MSC (Mobile Switching Center) which controls the call and data of your mobile and all this signal is transferred by microwave antenna.

while we Talking about the international network connectivity, all the MSCs are connected to the international switching centre and these stations are connected through fibre optic cables, microwave or satellite. Broadband is also connected to these fibre optic cables.

Although the internet speed is very fast from this network, but its limit is that we get either connection through broadband cable or which is not possible everywhere or from mobile tower, which is about 80km in range but 4G. In or range is less than 10km, while in 5G it decreases further.

Satellite internet

In such a situation where broadband is not available and the mobile signal is also low, in such a situation we will soon have another option and that is satellite internet, in which you have to take a receiver like a dish antenna which is Will connect directly to the satellite, which you can connect to the wireless router and use like WiFi.

Currently, Bharti Airtel and Hughes India and Viasat etc companies are offering satellite internet. But right now their range and internet speed is not so good and at the present time, it is quite expensive too.

We are talking about Alon musk's company Space X, which has jumped into the field of satellite internet to raise funding for its marsh project and has started launching 4445 satellites under the name Starlink. Apart from this, Samsung and Amazon have also planned to launch an equal number of satellites.

How will satellites provide internet from space?

So where the normal Geo Synchronous satellite is located at an altitude of 3600 km from the Earth, the same Starlink will place these satellites at a height of just 550km in the lower earth orbit of the Earth ie Leo Orbit, which will improve its signal strength and from there to the satellite It will communicate with each other via a laser to reduce the weather interface in the signal.

It is being sent to these satellites with a Reusable Rocket which will be located in one place on its orbit and will match it with the speed of the earth and travel at the same speed and cover that particular area. Now because of so many satellites, it will cover every part of the earth and their connectivity will be present everywhere from ocean to mountains.

Although many countries do not approve of satellite internet like satellite phone due to security reason. Space X has applied for approval in India and if it is approved then we will be able to use it soon and maybe Its plans should also be cheap like Jio.

How much clear image can a satellite take from space?

is satellite See the time of the clock tied to our wrist from space

पढ़े: हिंदी में

Do you know that there are about 2700 working satellites in our Earth's orbit now and this number is constantly increasing, when we see the stars moving in the night, it is not the soul that goes to heaven but it is the satellites that are always above us that Keeping an eye on us.

By the way, if the moving star is blinking then it is a plane because the satellite does not have its own light and it glows from the reflection of the sun and takes energy from the solar panel. What we are talking about in this article is the image capturing powers of Earth Observing Satellite and how much clear image can this satellite take from above on earth?

What is Earth Observing Satellite?

Although there are usually about 14 types of satellites such as astronomical, navigational or weather satellite, but we are talking about Earth Observing satellite which we also call remote sensing satellite, which is situated at an altitude of about 800 km from our earth and it can take the image of our Earth from space and till last year their number was about 446.

With the help of photographs taken from these Earth Observing Satellites, important tasks like covering agriculture, water resources, urban planning, rural development, mineral prospecting, environment, forestry, ocean resources and disaster management are done. With its help, a picture of the things on the earth appearing in Google map etc. is taken.

Now the question is how much clearer image this satellite can take from above, so let's first watch this video.

So the clearness of an image is from its resolution and in satellite there are five types of resolution which are spatial, spectral, temporal, radiometric and geometric resolution. So, first of all, let's talk about the five resolutions.

Spatial resolution

It tells the length of one side of a pixel in a satellite image, ie how large a pixel of the image covers an area, and the lower the image, the clearer the image will be. For example, if the spatial resolution of an image is 30 meters, then every pixel of it will represent an area up to 30 meters.

Similarly, an image of 10 meters spatial will represent 10 meters area and will be 3 times clearer than images with 30 meters spatial resolution.

Spectral resolution

The spectral resolution represents the wavelength interval size of the image and the higher the spectral resolution, the more colourful the image is. There are colours in the image according to how many bands exist in the spectral resolution. For example, only black and white colour in 1 band spectrum and RGB colour will be present in 3 band spectrum. Today's satellites can take images with 14 bands.

Temporal resolution

Temporal resolution shows how many time intervals a picture is taking of any given location, that is, the satellite makes a clear image by adding all those images repeatedly taking the image of any place in a span of few days.

Radiometric resolution

Radiometric resolution is the ability of a sensor to differentiate into different gray-scale values. It is measured in bits and refers to the ability of a satellite's system to record the brightness and contrast of several levels. With this, greater differences in reflections can be seen on land surfaces.

Geometric resolution

Geometric resolution How effectively any part of the earth can be represented in a single pixel of the image, also known as GSD.

Any earth observing satellite takes a clear image of any part of the earth with the help of these five resolutions.

Is satellite See the time of the clock tied to our wrist from space?

o know how small a satellite can take a clear image, the first thing is the spatial resolution of the satellite, so far it is the highest in GeoEye-1 satellite which comes with a special resolution of about 40 cm. While satellite can take images up to a ground resolution of 5 or 6 centimetres in a given time interval with the help of temporal resolution.

So now it comes to how much this interval is, then this interval is of several days until the satellite revolves around the earth in its orbit.

So now talking about what we can see in the resolution of 6 cm?

In this resolution, you can see from the car parked in front of the building, plant and house to the shoes of a man. But its spectral, radiometric or geometric resolution is so low that one can get a rough idea of the vehicle, but it is incomprehensible which model is there, and our shoes have a very blurred image.

So according to this, it is not possible to see whether you have worn the watch in your hand in the satellite image, then how much time is there in it will not be visible from the satellite at all, yes with the help of new technology in future It is possible.

By the way, if you have ever cultivated cannabis in your garden or roof, with the help of old photos of the satellite, the police can surely arrest you because this image remains in store for many years.
