What to do if your smartphone goes out. What to do if the phone does not turn on. We look for the reason and reason

In the modern world, it is impossible to imagine a person’s life without a telephone. Every person has this little helper. It makes it easy to contact the desired subscriber. But imagine that your Android phone does not turn on. What to do in this case? Of course, without a smartphone it will be quite difficult. If you do not have a spare gadget, then you need to quickly repair your device. In this article we will look at why your Android phone won't turn on.

Mobile check

If the phone stops turning on, then you should not immediately disassemble it and see what could have happened there. Of course, if you do not have certain knowledge, all these actions can be detrimental to your smartphone. Subsequently, repairs can only become more difficult and expensive. Why won't my Android phone turn on? What to do in this case?

Before you take drastic action, you need to check - maybe it’s not broken at all. First, you should find out whether the battery is charged, or perhaps the reason is a software failure of the device.

Checking the mobile device battery

As we have already found out, the phone may not turn on due to low battery charge. We put the smartphone on charge and wait about 30 minutes. After that we try to turn it on. If the phone was able to be “revitalized,” then the problem is high battery consumption. How can this be fixed? It is enough to turn off Bluetooth and Wi-Fi after use. These elements are constantly working to search for a possible network in order to inform the user about it. If you turn these items off, you will be able to retain the charge for a longer period of time. You should also reduce the brightness on your smartphone, as a bright screen uses a lot of energy.

If you have a function on your mobile phone that allows you to change the brightness automatically based on the room illumination, then you should turn it on. Let's return to the problem. If you managed to turn on the phone while it is charging, then let it stand like that for about 4 hours. It is worth checking the expiration date of the battery - perhaps it is time to change this component. If the phone does not turn on, but Android is charging, you need to consider other possible situations.

Smartphone power button

The phone may blink but not turn on. This may be due to a faulty power button. The reasons why it may not work can be different:

• If you just purchased a mobile phone and it does not turn on, the power button may be faulty, and the reason lies in a manufacturing defect. What to do in this case? You need to contact the store where you purchased the smartphone and ask for a refund, to replace the phone or to have it repaired. The seller is obliged to do something in this case.

• Another reason is also possible, which is already associated with your carelessness. If you spill liquid on your mobile device or drop it, there may be various reasons why your phone will not turn on. In this case, you should not disassemble the device yourself. Of course, if you have a warranty, you can try contacting a service center. Otherwise, you will also have to resort to the help of a professional. Unfortunately, even he is not able to fix any phone.

Memory card

So, your Android phone won't turn on. What to do? The reason may lie in the SD card. Your phone may not support a certain memory card, causing your mobile device to freeze or not turn on at all. You should choose a memory card in specialized stores, having previously found out that it will fit your smartphone. If different memory cards cause the same effect, then the problem is with the phone. In this case, you need to reflash the mobile device. You can do this yourself, but you should be careful, as you can only cause harm.

Phone won't turn on after Android update

Sometimes situations happen with smartphones when it does not turn on after an update. As a rule, new gadgets are more prone to this. Various updates come to your mobile device, which, unfortunately, are not safe. Usually smartphones that have constant access to the Internet are susceptible to this. After such updates, the phone may randomly turn off and turn on after a while.

Another situation is also possible: you try to turn on your phone, and the Android text lights up and nothing else happens. Reboots return the phone to this problem again. So, your Android phone won’t turn on again. What to do? In this case, you should try turning off the device and removing the battery for a few minutes, then turning it on and resetting the settings. If the problem was not serious, then everything will work out, and after a while the phone will return to its previous state.

If it refuses to work adequately, then you should use a hardware reset. This will clear your phone of updates and all information. But, most likely, it will return to working condition. Of course, all your personal information will disappear, but getting your phone back to its former life will probably be more important. This reset will be carried out differently for each smartphone. You need to find a suitable method for your model. Your phone won't turn on after a factory reset? Unfortunately, this solution may not be suitable for Android. In this case, you will need to reflash your device.

After flashing the phone does not turn on (Android)

If you unsuccessfully reflash your device, it may not turn on or freeze at the Android logo. What to do in this case? Of course, you will have to reflash it again.

First, go to the manufacturer’s website and look for the necessary firmware that will fit your model. You should not search for firmware through a search engine, as it will return many different programs that most likely will not work. This way you can only aggravate the problem and bring your smartphone to a “brick” state.

After the firmware the phone does not turn on. It is still possible to bring Android back to life. You will need to install the new firmware correctly. If you do not know how to do this, then you need to contact the service center. This way you can be sure that everything will be fine with the phone.

Mechanical damage

The most common cause of smartphone failure is mechanical damage. If the phone is dropped or you spill liquid on it, then this is a serious problem that cannot be dealt with so easily.

If the fall was not serious, then you can try to remove the battery, SIM card, SD card. After some time, we return everything to its place. If the phone works, then you are lucky, and its contacts simply went missing. Otherwise the problem is more serious. If you do not have the necessary knowledge, then you should not try to disassemble and repair a mobile device yourself. In this case, contact the service center.

The Android system is the most popular among users.

All modern manufacturers of modern devices use the Android operating system:

• Motorola;
• Sony;
• Samsung.

Nowadays, not only expensive phone models have the Android operating system, but also budget options. Therefore, most touch models currently use this operating system.

At the moment, the absolute owner of the Android company is Google.
In July 2005, Google acquired Android Inc.

The first version of the Android system was released in September 2008.

Living in the modern world, modern gadgets have become a part of our lives; when they stop working, we often panic. Not turning on your favorite Android smartphone is a headache for many users.

First you need to understand the reason for the device’s failure to work normally. The reasons for this are varied, they can be hardware or software in nature.

Reason #1

One of the reasons for the device not turning on may be that the battery is completely discharged.

Therefore, remove the battery from the device and charge it with an external charger like a “toad”. Since the standard “charging” is not powerful enough, and will not help you if the battery is completely discharged.

Such a charger will boost your battery, and in half an hour you can use your smartphone.
Sometimes, to reboot the device, it is enough to remove the battery from it, wait a few minutes, reinstall it and press power.

Reason #2

If your mobile phone's screen lights up when you turn it on, but then won't turn on, then a full reset of Android settings may help you.

Let's describe step by step how to do this:

• We take out the battery, after 30 seconds we put it in place.
• Press the volume key, where + and at the same time the power button of the device.
• Use the volume up or down button to select the Settings menu – confirm with the power button;
• Then select the system formatting line - Factory reset;
• In the next window, select the line Reboot system now.
• Your smartphone will then automatically restart.
• And when the auto-reboot ends, you will be able to successfully use your device.

A significant disadvantage of previously installed programs will not be present; pictures and contacts saved on the device will also be deleted.

Reason #3

If you drop your phone, it may not turn on again. Here you will no longer be able to cope with the problem on your own; you will need to turn to specialists for help. Moreover, if after a fall the sensor on the phone does not work, then this will help you figure it out.

Since you cannot do without phone repair skills, do not disassemble the device yourself, but take it to a workshop or an official service center for the model of your device.

Reason #4

Often, after contact with water, the device stops turning on. It is urgent to remove the cover and remove the battery, dry the smartphone with a hairdryer with a cold stream of air. Or a warm stream at low speeds. Alternatively, lower your smartphone into the rice. Rice tends to quickly absorb moisture.

After burying your smartphone, you will have to wait 2–3 hours until the moisture is completely absorbed.

Reason #4

Another possible reason for the smartphone not turning on could be a broken power button. When your device is under warranty, contact the store where you bought it or a service center; if not, then go to a repair shop.

There can be many reasons for such a breakdown, from a manufacturing defect to the device falling and the button contacts coming off.

Reason #5

It happens that after installing an application, after a while you receive a request to update it, and the update is not suitable for your phone model. After installing it, you will encounter various problems like turning off your smartphone; to fix the problem, remove the battery and wait a couple of minutes. But from this article you can find out why the phone turns off by itself and how to fix this problem.

Then turn on the device and remove the frozen application. If these manipulations do not help, then use the reset described above.

In the video, what to do if the phone does not turn on Android:

What to do if nothing helps

If the tips described above for bringing your smartphone back to life did not help you, then repairs will be necessary.

The cost of services will vary depending on the cause of the breakdown and the high cost of the spare part itself that will have to be replaced:

• If your contact comes loose when you fall, it won't cost much.
• Reflashing the device is also an excellent option for solving many problems with turning on the device; you should not be afraid of it. Most often, after flashing the device, it works better than before.
• Diagnosis of breakdowns in all service centers is free. If you ask for diagnostics, they will find out if your device is broken within half an hour. They will tell you the cost of repairs, we will consider approximate prices.
• The cost of replacing the battery at a service center will cost from 1 thousand to 1200 rubles.
• Replacing the charger costs about 600 rubles.
• Replacing smartphone firmware costs 1000–1300 rubles.

If your phone does not turn on, this can make any user nervous, but in any case, before taking the device to a service center, you can try to provide first aid to resuscitate the smartphone. Problems due to which the phone does not turn on can be either software, for example, a problem with the firmware due to an unsuccessful update, or hardware, for example, due to a failed battery.

Below we have tried to put together a lot of tips that will help you figure out why your phone won't turn on. If none of the tips helped you, please describe your problem in the comments.

The phone does not turn on after repair.

If you decide to disassemble the phone yourself, and after assembly it does not turn on, then the problem may be that you simply forgot to connect power to the motherboard of your device. You must disassemble it again and make sure that the power supply circuit from the battery to the motherboard is not broken and all cables are in place. If you have a multimeter, try checking the voltage on the battery, or after assembling the phone, try putting it on charge. Almost all phones notify you when charging starts, even if the device is turned off.

What to do if water gets into your smartphone

Let's look at the hardware reasons why the smartphone won't turn on.
One of the reasons may be falling into water. What to do if your phone falls into water? First, remove the battery, you need to do this as quickly as possible, then dry your smartphone with a hairdryer. Control the air; it should not be hot, otherwise the touch glass and some other components will simply begin to peel off. Then, without inserting the battery into the smartphone, put it in a warm place. It is worth noting that you do not have much chance of salvation and it may not be possible without losses. In particular, the buttons on the device may stop working. If you have dried your smartphone, but it does not turn on, it needs repair at a service center. The worst thing that can happen is replacing the system board, which, by the way, It costs as much as a smartphone itself.

The smartphone does not turn on after being completely discharged.

This problem is observed in some modern smartphones. In particular, Sony phones. Some Sony phones had such a feature that it was impossible to turn them on after being completely discharged if the phone was in this state for a long time. One thing helps - long-term charging of the battery with a current of 2A. And these are almost all chargers.

In any case, as I already wrote above, you need to put your smartphone on charge for several hours. Usually the problem goes away on its own. You can try a charger with a higher amperage, for example, 1.5 or 2 Amps.

Also try making your smartphone.

Check the battery. The phone may not turn on due to a faulty battery.

This is a must. If you have a removable battery and can install another one, do so. Sometimes, although not often, the problem that prevents your smartphone from turning on may be the battery. By the way, is your battery fully charged? Maybe this is the case?

With some phones, especially if the phone is several years old, the actual battery charge may not match what your phone shows. If your phone won't turn on, try charging it for a few hours. It is possible that the battery will charge and the phone will turn on.

The battery wears out very quickly. Many mobile phone manufacturers provide a one-year warranty on the device itself, and half a year on the battery. The reason for battery failure is quite simple - a very heavy load on it. We constantly charge our phone, and as you know, batteries lose their charge with each charge-discharge cycle. For example, standard lithium-ion batteries installed in our phones work properly under load for no more than two and a half years.

Check the charger.

If your smartphone is dead and it won’t turn on again, maybe it’s a charging issue? Try charging your device from your computer. If the phone shows no signs of life within half an hour, the problem is not with the charger. If the phone seems to be charging, but cannot charge, check the charger on another phone. It is quite possible that it will need to be replaced with a new one.

The phone does not turn on after being dropped. Mechanical damage.

Smartphone manufacturers like to say that their phones cannot be scratched, drowned or broken. Manufacturers give their phones Gorilla Glass screen protection, IP67 water resistance, shockproof casing, and so on. Despite all the phone protection measures taken by companies, it often happens that the phone does not turn on after being dropped. For example, on asphalt or falling into water. Unfortunately, all that can be done at home after a fall is to see if the battery, power cable or display cable has come loose, if there is a sound or vibration signal to turn it on.

It’s unlikely that you can do anything more with a dropped phone at home. To do this, you need to check the voltage on the battery and on the system board. If your phone is dropped and won’t turn on, and you don’t have the necessary tools at home, you will have to take the phone to a service center.

After the firmware the phone does not turn on.

One of the most common reasons why a phone may not turn on is due to an incorrectly installed firmware or update. After flashing or updating the phone does not turn on due to incorrect installation of files. In this case, you will need to flash the phone. For example, if your Samsung phone does not turn on, then you will need to download the firmware from the official Samsung website and the Odin flashing program. Using this program you can flash your phone. All settings and files on the internal memory will be deleted, but there is a chance that the phone will turn on.

If Lenovo phone won't turn on, then in this case you will need to enter Recovery mode by simultaneously pressing the power and volume up keys. In the Recovery menu you will need to select the wipe data/factory reset menu item, and then Yes - delete all user data. Unfortunately, different phones have different ways to access the Recovery menu. If you are sure that you installed the official firmware or an official update, then contact the manufacturer’s authorized service center, they will restore the firmware.

But we recommend you try perform a Hard Reset by resetting the phone to factory settings. Very often this helps if the phone does not turn on. Below we have selected key combinations for popular phones.

Samsung phone won't turn on: Press and hold the volume rocker up, the center menu button and the power button at the same time.

LG phone won't turn on: Press and hold the power button and volume down button at the same time, then select wipe data/factory reset.

Huawei phone won't turn on: Press and hold the Volume Up key and the Power button at the same time. You can try pressing the home button, volume up key and power button.

If your other phone does not turn on after flashing, write the exact model in the comments. We will try to help you.

The phone turns on and turns off immediately, what should I do?

It often happens that after updating or installing a program, your phone turns on and immediately turns off. Usually it looks like this: the phone turns on, the logo appears, the boot process takes place and the phone goes into an eternal reboot or turns off. There can be a lot of problems here, from the firmware to the battery. If you have a problem with your phone after flashing or updating the device, then roll back to the previous firmware or reset the settings. Will help.

Sometimes the phone turns off while the device is booting up. Consider your phone does not turn on and the advice from the previous paragraph will help you. You must perform a HARD RESET or flashing the device using a computer.

If you have not updated the firmware, then the whole issue may be the power button, which “sticks” and turns off the phone. Unfortunately, this happens very often, especially if the phone ends up in water. In almost all smartphones, the button is soldered to the motherboard and can be replaced.

If The phone turns off and turns off immediately after the complete download, when you see the desktop and icons, then try to remove the last installed programs, if, of course, you have enough time for this.

The phone may turn off immediately due to the battery. Check the battery and system board cables. Even if a smartphone has a “non-removable” battery, removing it is not that difficult. In any case, if you are sure that the problem is not in the firmware, then you can most likely find out exactly the problem due to which the phone turns on and off immediately at a service center. Again, the problem is either in the firmware or in the power circuit.

These simple steps can help you provide first aid if your smartphone won't turn on. If none of these points suits you, take the device to the store if it is under warranty or to a phone repair service center if it is no longer under warranty.

Telephone - Despite the continuously developing information system, these small means of telephone communication continue to remain at the peak of their popularity. Thousands of residents cannot imagine how their life would change, what direction it would turn in, if they did not have this small but irreplaceable assistant at their disposal, like a telephone or smartphone. Many will agree that this is not even a communication device, but an extension of the hand, whose malfunction can cause serious discomfort. Many people cannot afford to be left without a phone for a minute. What if at this very second an important message or call arrives on the device, which will radically change the course of events in the life of the phone owner. And extreme panic can begin the second the owner of the smartphone realizes that there are some problems with the device. It’s okay if the music file doesn’t open, or the pictures on your phone have become more blurry and inaccurate. But what if the phone turns off and then doesn’t turn on at all? What to do in such a situation? Start ringing the bells and turn on all your friends who may also have had this situation, or find an experienced specialist who can correctly understand the “whims” of the phone and return its owner to the usual rhythm of life as quickly as possible. After all, some people have absolutely no idea how they can sleep, watch TV, or go to an important meeting without such a faithful telephone, which is already integral to the human essence. It’s good if the phone has faithfully served its owner for many years and he can afford to be capricious, but if a failure occurs in a brand new smartphone, then the nerves and peace of mind of the smartphone owner are in big question.

Don't harm yourself!
The first thing to do if your phone turns off and won’t turn back on is not to panic. At such moments, there is a high probability of taking actions that will further aggravate the situation.
What do almost everyone whose smartphone won’t turn on do? Everyone opens the cover of the phone and begins to look and find out what is going on with the phone? What part could fail? And to clarify these questions, everyone starts pulling wires and nuts. You shouldn’t do this if you want to leave even the slightest chance of restoring your phone. The fact is that a person who is not familiar with the secrets of a smartphone is unlikely to be able to independently find the cause of the breakdown. It may be a small thing, but excessive curiosity quickly turns a minor problem into a bigger nuisance. Who knows, maybe the only reason is that the battery suddenly ran out and the device itself just needs to be charged. Experts identify a number of reasons that can lead to such a problem as the phone not turning on. Let's talk about this.
1. Check the battery.
Just a couple of minutes ago, the phone was working correctly, and there was no sign of trouble to come; this is how those smartphone owners who have already encountered this problem can characterize the situation.
The charger on the phone showed an almost full battery, so you could forget about recharging the device for the whole day. However, it is worth considering the fact that modern mobile devices equipped with Wi-Fi or Bluetooth options can consume many times more energy. The thing is that the phone is constantly searching for a new available network, which would allow the owner to access the Internet. This uses a lot of battery energy. Of course, these functions are indispensable for the modern user, but you can turn them off and turn them on only in those moments when this service is needed. Otherwise, the phone's battery is discharged in a matter of seconds, and is completely impossible to manipulate, which would allow the phone to turn on again. In this situation, the only thing that can solve the problem is to put the phone on charge! In some cases, the battery will only need half an hour before it can return the phone to working condition, and some smartphones take about a day to charge and only then turn on again. It all depends on the condition of the battery itself.
2. Check your charger!
If the smartphone does not turn on again, even after being charged for more than a day, then in this case it is necessary to inspect the charger itself. Who knows, maybe some wire in it has become disconnected, or some contact has come loose? The problem may also lie in the phone socket. Indeed, in modern devices it has only one hole, which performs many functions - charging, headphones, connecting to a computer, etc. The only option to check the functionality of the charger is to charge the phone using a frog battery. If your phone starts working fine, get a new charger.
Other people's chargers can also damage your phone. Many cases have been identified where expensive mobile devices have become unusable due to the fact that they came into contact with someone else’s chargers that were not suitable for their type. This can lead to a more serious problem, which can only be resolved by flashing the smartphone.
3. On/off button
Another reason that may explain why the phone does not turn on is a malfunction of the button responsible for turning the mobile device on and off. There could be a lot of reasons for this. In the case of a new device, all responsibility lies with the manufacturing company, which could have made a mistake and a defect occurred during production, leading to the inoperability of the button. The owner must contact directly the store where he purchased his device. There they may offer him a new phone, or they will suggest contacting a service center, where they will try to find out the cause of the breakdown and try to fix it.
In the case of an older model, when you can be more confident about the condition of the buttons, such unpleasant incidents can also happen. It only very often happens that if one button fails, then the entire keyboard may not work. A number of cases can lead to this: the phone was dropped, which caused the keyboard to move, or moisture got into the device, which has a more detrimental effect on the device. Regardless of the reason, you need to contact a specialist who can identify the cause of the button’s inability. You may be offered several options in the future:
replace the keyboard panel;
perform a complete cleaning of the mobile device;
partially or completely replace the keyboard controller.
Even the most ordinary flash drive can be the reason why your phone is not working. In many cases, mobile devices are released without a memory card and the buyer must purchase additional memory for his device. Often the selected model and manufacturer turns out to be incompatible with the telephone device. You should buy flash drives only in trusted stores that sell original products from reputable manufacturers. It is also necessary to check the compatibility of these two systems in the store. Place the flash drive in your phone and try to turn it on. If the phone immediately begins to freeze or does not see the device itself at all, then you can safely return the selected flash drive to the seller. If the smartphone refuses to work with any type of flash drive, even with minimal memory, then you will have to contact a service where they will reflash the device.
4. Installing updates.
Who doesn't love downloading new updates to their phone? Especially if you have full access to the Internet, and there is certainly something interesting to download to your device. But not all updates can benefit a smartphone; some updates are incompatible with the features of the mobile phone system, which leads to device failures. If this is the case, then the phone immediately begins to send signals that the new application is not in contact with the phone. The device just starts to glitch. Inscriptions are periodically displayed on the monitor, the phone can turn on and off on its own. What should you do in this situation? Turn off the phone, remove the battery, wait a couple of minutes, then turn it on again and quickly delete new applications and settings that have been made recently. Even if you did everything correctly, the device will take time to return to its previous functionality.
If the phone is not restored, then you will have to take more serious measures to wipe the phone - a function that removes all phone settings and returns the previous factory settings. This function does not affect the content of the SIM and memory card, and everything else is updated.
5.The cause of the problem may be mechanical damage.
When presenting a new smartphone model, every manufacturer praises their products, but modern phones shouldn’t be called invulnerable either. Many people often put their phone in the back pocket of their jeans. If you bend or sit down poorly, the phone will fall and may break. It’s good if the phone just doesn’t turn on yet, but this can still cause a lot of troubles that will have to be addressed to a service center.
At first glance, smartphone owners do not find any damage to the device and cannot themselves explain why their phone failed. Maybe you lent your phone to someone, but it was dropped and they didn’t tell you? Anything can happen. It may even be that the co-owner of the phone did not notice how he sat down and damaged his smartphone.
First you need to restart the phone, remove the battery, put it back in place and try to turn on the phone. If these measures do not lead to the desired result, the phone does not turn on, then you need to urgently contact a specialist; perhaps the contact has come loose and the phone can be easily repaired. In many cases, the service center offers to reflash the phone, arguing that this is the only way to restore the phone’s operation. In some cases this is true. There is no need to be afraid of flashing the firmware; the device will work as before, maybe even better.

Given:

• a working phone or smartphone that is dead. Didn't fall, didn't get wet, didn't get stitched. The battery died and that's it;
• working charger.

Most likely the battery in your phone has discharged below 3.2 Volts and has been blocked by the microcircuit in the phone. This is a feature of Li-Ion type batteries. To put it simply, the battery cannot operate until the voltage rises. The battery can be unlocked at a service center. But there are several methods that you need to try yourself:

• charge the battery in the universal “Frog” charger (you can use an old charger if you cut off the plug). Keep it on charge for a few minutes and insert the battery back into the phone. The phone will turn on and charge as usual.
• conjure with the power buttons, simultaneously pressing the volume and power buttons, reboot. Remove and reinstall the battery. Leave the phone on charge for a long time. After some time (up to several hours), the phone can be turned on.

What to do if the battery cannot be removed (smartphone or phone is not collapsible). Doesn't respond to buttons and won't charge?

Place your phone on charge and heat it with a hairdryer. When heated, the battery voltage will rise slightly and the phone will begin to charge.

Power consumption of smartphones

Studies have shown that popular free smartphone apps spend up to 75% of their energy tracking users' location, sending that information to advertisers, and downloading ads. “It turns out that free apps are not really that free. They have hidden costs associated with power consumption and reduced battery life, said Y. Charlie Hu, a professor of electrical engineering at their Purdue University. – Energy consumption is the most important characteristic for mobile devices. The smartphone battery should be small and light.” The professor led the effort to create a tool called ePro (from “energy profiler”), which analyzes the energy consumption of a smartphone.

The findings show that between 65 and 75 percent of the energy used when running free apps is spent on advertising-related features.

“We conducted an in-depth case study identifying the six most popular smartphone apps, which included Angry Birds, Facebook and Android Browser,” said Abhinav Pathak, a doctoral student at Purdue University.

It has been shown that the free version of Angry Birds spends 75% of its power on running “advertising modules” built into the software code, and only 25% on the game itself. Modules perform marketing functions such as sending user information and downloading advertisements.

“We believe that the app sends information about the user's geographic location, so that downloaded advertisements can be targeted to a specific area - a kind of geo-targeting,” said Professor Yu Charlie Hu.

Excessive smartphone battery drain is caused by a number of factors, including inefficient application code and software glitches. The Eprof program shows how much energy is spent and for what purpose. In this particular case, it was discovered that a piece of code embedded in a free application was unsuccessfully trying to establish an Internet connection by calling another piece of code, trying to solve the problem that way and wasting energy. Energy inefficiency is usually present in interactive programs such as games and applications that use built-in smartphone devices (GPS, camera, position sensor).

The specific cause of energy inefficiency is called the “tail” in professional circles. After the application sends information over the Internet, the “networking unit” should switch to a lower power consumption mode within a few milliseconds. However, the researchers found that after the ad modules finish using the network connection, the communication device continues to operate at full power for about seven seconds.

“Tails” are phenomena of the hardware components of smartphones (including 3G, or third generation wireless systems, GPS, Wi-Fi), and are not a drawback of the software itself. However, software developers could work around these bottlenecks by minimizing the tail effect, says Professor Y. Charlie Hu. – Every time after using 3G there is a “tail”. The ad module in Angry Birds apparently uses the 3G network to send information and load ads, while the game itself does not require a network connection. That is why we blame the advertising module for wasting the battery.

The current consumption of a smartphone battery has long become the “bottleneck” of this mobile device. “We've heard a lot about problems with battery energy use,” said Professor Yu Charlie Hu. “Consumers expect a smartphone to last at least a day on a single charge, but in reality, we've heard of cases where the battery only lasts a few hours. This is something users often complain about on Internet forums.”

What to do if nothing can be done with the phone?

It’s impossible to turn it on, there’s no point in taking it in for repairs (the phone is outdated, the screen is broken). It is logical that you need to buy a new one. In this article I reflected the current 2018 models of the Chinese brand Xiaomi. Optimal ratio of quality and price. For $100 a new cool smartphone, for $200-250 a top-end smartphone (competitors are at least $100 more expensive). I’ve been using it for 3 years now and don’t regret anything, although before that I was a fan of Sony for more than 10 years. And in general, the young company Xiaomi is simply tearing up the market and is already in 5th place in smartphone sales in the world.
