Android smartphone does not turn on. Guaranteed solution to the problem. The phone began to discharge quickly - what to do?

What could be the reason that the Android battery drains quickly? And most importantly, how can this be fixed? This article will discuss the main causes of this problem and ways to solve it.

Small battery capacity

The most banal reason for this is its small capacity, that is, less than 1600 mAh. Unfortunately, in this case, you can only put up with what you have and try to use the minimum energy on which the smartphone runs wisely. This means following tips such as not running unnecessary applications and disabling unnecessary functions. The actions that need to be taken in such a situation will be described in more detail in the article below.

Battery wear

Sooner or later, all batteries come to this point. And the battery on Android sometimes discharges quickly due to the fact that during the use of the device it has worn out and needs to be replaced. You can match the original battery to the model, but this is difficult and expensive, you can buy a fake or use products from battery manufacturing companies like CRAFTMAN, which supply universal batteries for smartphones, tablets and other gadgets. In any case, choosing a new battery is not so difficult: there is enough choice on the market for technical products.

Running programs as a factor in why the phone battery drains quickly

Android is an operating system, which means that after downloading and closing any program, you cannot be sure that it will not remain running. Many running programs are another reason why the battery on Android quickly drains. What to do? First, use the built-in or advanced cleaning options. Secondly, reboot the device from time to time, as is done on computers and laptops to reset the operating memory. This not only saves battery, but also simply helps your smartphone or tablet work faster.

Unstable communication signal

Recently, many mobile operators have been offering 3G coverage to users, but almost always it is, to put it mildly, unstable. This means that when moving around the city, the network on a smartphone or tablet with a SIM card is forced to constantly switch from regular 2G to 3G. Because of this, the battery on Android also drains quickly. To prevent this from happening, you can force only GSM in the settings.

GPS

Many Android devices have GPS enabled by default. But in reality, only a small number of people use it. That’s why you can safely disable this function if it’s not needed, since it only once again “loads” the phone and takes energy from the battery. Even if this function is in active use, you can enable it only when there is a real need for it.

Screen brightness

The screen brightness can be adjusted. And there is a clear proportional dependence of the energy supplied by the battery on its value. A very bright screen is rarely something you can't do without. Among its disadvantages, in addition to the above, is also excessive strain on the eyes. All you have to do is choose the ideal value for yourself. In addition, information on a dim monitor is much more visible in strong sunlight.

Tips for extending your device's battery life

In addition to eliminating the reasons described above, you can also use the following tips to extend the battery life of your Android device. Their effectiveness on different gadgets may vary, but it has been tested by time and other users.

Battery calibration

Battery calibration is the process of bringing the battery into an optimal state for use. This is done because the device may incorrectly remember the charge level and its consumption, as a result of which, even if in fact the level is 95 percent, the device perceives this incorrectly and the smartphone/tablet turns off. If you simply replace the battery, the problem will remain, which means that your efforts will be wasted.

To calibrate the battery on GooglePlay, you can download the corresponding application, but you can also do it manually. First of all, you will need to completely discharge the device, remove and insert the battery back without turning on the device, charge it to one hundred percent, carry out the actions with the battery from the previous point, and turn it on.

In fact, there are many calibration options; you just need to choose the one that suits you.

Disabling automatic system updates

It is known that disabling automatic system updates not only extends the battery life of the device, but also prevents unnecessary downloads, and therefore reduces Internet traffic costs. It is recommended to set "Ask before installing updates" in the settings. They are available on GooglePlay in the "My Applications" section.

"NO!" unused processes

It is recommended to regularly clear memory of unused application processes, clear temporary data, Internet browser cache, etc. To do this, you can use both standard system tools and additional ones.

You should not download applications that supposedly save battery capacity; in fact, they only load the system even more.

If the battery on Android runs out quickly (Samsung, for example, often suffers from this), you need to turn off all unused networks, uncheck “auto-rotate screen” and “auto-brightness”.

Special advice for smartphones with an AMOLED screen: it is recommended to install dark themes rather than bright and light ones.

Additional actions

If you approach the matter of discharging your Android smartphone/tablet with all responsibility and foresight, you can also do the following:

Buy a high-power battery that will definitely guarantee a long charge life. Such batteries are usually thicker than regular original ones, and they come with an additional back cover, which makes the gadget heavier and larger in size.
There is also an option to purchase a battery case. The disadvantages of this and the previous points are that they are not possible for all devices.
You can purchase a portable charger, as it is also called an external battery. It allows you to connect your phone to it and charge it again. It itself is usually charged from an outlet. high-capacity, so there is no risk of sudden shutdown of the device.
Buying just an extra battery is another effective alternative. When one runs out, you can simply replace it with a spare one, especially if the Android battery is quickly draining.

One day, a tablet or smartphone on which the Android operating system is installed refuses to start and/or does not charge. In fact, everything is not so difficult: you need to accurately determine the reason why the device behaves this way.

Reasons why an Android smartphone or tablet does not turn on or charge

There are several reasons why the device does not take a charge and does not turn on.

Completely discharged battery. This happens when the tablet has been left for many days with a discharged battery. Due to self-discharge, the voltage in the battery has dropped so much that standard “charging” is useless. Overdischarge of the battery leads to the fact that attempts to charge it with standard “charging” lead to nothing - the gadget shows no signs of life. At the service center, they open the case or remove the outer covering of the battery (from the end where its own controller is located) and supply the required voltage “bypassing” it with a special power supply. You can use a “smart” charger that “trains” the battery using a different charging algorithm, without opening the battery itself - such as, for example, Cadex brand battery analyzers. If the battery capacity has greatly decreased - less than 70% - the specialist will train it (full charge-discharge cycles). If training the battery still does not produce any results, the battery can be replaced with the same one. Then everything is put back together and the battery is charged from a standard charger.
Faulty charger. Any part in it can fail. This happens less often than a wire break. Anyone who does not want to repair the charger himself buys a new one. Eliminate counterfeits, use the original branded “charger” from the manufacturer of your device, or charge your gadget from the USB port of a computer, TV, car cigarette lighter or USB-Hub.
Equipment failure of a smartphone or tablet. Hardware failures and device breakdowns, for example, a broken screen. Take your device to a service center for diagnostics. This will solve the issue of the cost of repairing your gadget.

How to turn on a device if it does not charge at all and does not turn on

There are several common reasons why a device may not turn on.

Android system crashes when starting

If your device does not turn on, the Android system crashed when turned on.

Android system startup error

Remove the battery for 10 seconds. For most smartphones, especially inexpensive ones, this is done in a matter of seconds, but a tablet often has to be disassembled. You may need a special set of small screwdrivers.

Tablets and some expensive smartphone models may have a “mikrik” (micro switch) - a hidden small emergency reset button that you press with a paper clip or a needle. Hold it for 10 seconds. It is located both outside and under the back cover, next to the SIM card slots, SD card slot, and even in a place where you won’t immediately see it; sometimes it has a barely visible Reset inscription. Perhaps, after such a reset, the Android system on your gadget will start successfully.

Press and hold the reset button until Android reboots

Poor contact of the battery with the power terminals in the device

It happens that the terminals are worn out due to frequent “jerking” of the battery - this is immediately visible. Bend the terminals slightly outward so that they fit snugly against the battery terminals. Perhaps the battery terminals themselves are dirty or greasy. Clean them with any solvent (alcohol, cologne, acetone, etc.).

“Failed” terminals need to be bent or replaced

The battery is completely dead

If the problem is with the battery, buy the same one and take the faulty one to a service center for diagnostics. The same applies to the charger.

Replace the faulty battery with another identical one

Why does the device turn on but does not boot completely?

The tablet or smartphone turns on, but the Android system refuses to boot, getting stuck on the green Android robot logo, or loading the Android desktop after waiting for ten minutes. Causes:

In all cases - except the last one - reinstalling the Android operating system (flashing) on your device will help.

How to get your device to work if Android won't boot

In case of a normal startup failure, a hard reset of the Android software may help. This reset is performed in Recovery Mode. For each brand and model of device, switching the gadget to Recovery mode can be performed according to a separate scheme. Most often, you hold down the power button, Home button, and one of the volume buttons at the same time. The sequence of actions could be as follows:

Hold them down for 10-20 seconds to bring up the ClockworkMod Recovery menu.
In the Recovery menu you can reset your device to factory settings
Select Wipe data/Factory reset.
Select data clearing option
Select the item yes - delete all user data (“Yes - delete all user data”).
Click this item to confirm deleting personal data from Android
Then select the reboot system now option (“Restart the system immediately”).
Select system restart option to reboot your device

The ClockworkMod console menu of different versions changes little over time - new functions rarely appear as ClockworkMod is updated, but the ClockworkMod program itself is supported by an increasing number of brands and models of devices with each new update and runs on an increasing number of processors. Whatever version of ClockworkMod you turn out to be, you will have access to all the functions of reinstalling/resetting the Android system.

If the Android system is accidentally deleted from the ClockworkMod console or the Android OS is infected with a “virus,” only reinstalling Android will help.

If you are not sure, rush to an Android service center or similar, where they will help you “flash it”.

If the phone is Android, then we’ll look at how to deal with this and what can be done. It's no secret that Android uses up the battery to the maximum and that it barely lasts for a day. This is the situation with any Android smartphone, be it Samsung or anything else. The iPhone also discharges quickly, but we’ll talk about that in another article.

Android

There is a certain set of actions, by performing which you can achieve more or less economical consumption of battery power. You shouldn’t expect that the battery life from charge to charge will increase significantly; you still need to remember that Android itself requires good battery power. And if the main complaints are that the phone quickly dies down during the game, then nothing can be done here - for such games it is better to purchase phones that are equipped with a more capacious battery. It is quite possible that you can choose another separate high-capacity battery for your phone. Well, and of course, the more applications are installed on your phone, the faster it will sit down. Of course, today there are plenty of freely available applications, and they all seem to be needed. But if you do not use the application very often, then you can wait to install it. For example, applications for accessing Internet banking are, of course, a necessary thing. But you can purchase Russian Railways tickets directly from the Russian Railways website. How to register to purchase Russian Railways tickets online is described in detail at http://webereg.ru/servisy/rzhd-pokupki-biletov. That is, as a rule, you can do all important actions simply by knowing the site address. By the way, it’s good that not all companies release their own applications, because then you would have to choose, and this is a very difficult choice.
First, let's figure out in what cases it makes no sense to do anything with the battery:

Its resource has been exhausted.
There was physical impact on the battery.
The battery is swollen.

When charging, a different charger with the wrong voltage and current was used.

What takes the longest battery life in a smartphone?

The screen comes first, the communication modules come second, that is, the Internet, wifi, and so on. That is, even when the screen is turned off, your battery is guaranteed to run out if you do not turn off the communication module. However, Android has the ability to optimize battery consumption even in this case.

Screen

Whatever the device is, if it has a screen, then it is the main consumer of energy. Therefore, if your screen is very bright, the battery will drain quickly. It is better to set it in the settings so that the screen brightness is adjusted automatically, which will allow you to keep it at a less bright level in the room. However, not everything is simple here either - in this situation, the light sensor will also draw energy onto itself.
Plus, you can also save energy by reducing the time before the screen turns off.

4G LTE connection. Only in some regions of the country it is possible to keep this connection constantly on. In many other regions, this connection is unstable, and therefore automatic switches to 3G occur constantly, and this already means an uneconomical load on the battery. Just set 3G as your default connection. To do this, go to Settings - Mobile networks - More and change the network type.
Mobile Internet. In fact, it is better to turn off mobile Internet on your phone, because it is not always required. If your smartphone does not have a super-capacious battery, it will last longer if you monitor your Internet connection and connect to operator towers only when necessary.
Bluetooth. It is generally better to disable this module. If you use it sometimes, then it is better to turn it on at that moment.
Wi-Fi. As is already clear, it is better to enable this type of communication if necessary. Since the battery drains quickly and there is no particular need to always be online, it is better to connect to the wireless router only when required. In addition, turn off notifications about searching for and availability of wireless networks. To do this, go to “Additional functions” and turn off the “Network notifications” slider. Report the presence of public networks." And also turn off the “Always search for networks” slider.
GPS. This is essentially a sensor that comes with your smartphone. It does consume a lot of your battery power.

Disable sensors

The sensors include the GPS already described above, automatic screen rotation, NFC (communication module). It is better to disable automatic screen rotation, because it is a gyroscope that uses a lot of battery life. Android 5 Lolipop has the Google Fit app, where such sensors still work, but in the background. Therefore, here you need to disable the application itself.

NFC. Not all phones support NFC, but more and more devices do. Although it cannot be said that users often resort to it. Therefore you need to disable it. To do this, go to the settings section “Wireless networks” - “More”.

Turn off vibration feedback

Android has a built-in vibration feedback feature that is turned on by default. This refers to vibration when touching the screen. However, all mechanical movements (in this case, an electric motor) are quite energy-consuming. To disable this feature, go to Settings, then Sounds and notifications, Other sounds.

Applications

It’s probably clear that the more applications running on a smartphone, the faster the battery drains. You can see how much the battery drains from certain applications if you go to the Settings section, then Battery.
Games and the phone's camera are supposed to use more energy than other applications. And if a regular e-reader turns out to be a record holder for battery consumption, then most likely the e-reader software has its own problems. You might be better off finding another reading app with more adequate software. Then about various effects and cool transitions and animation - all this is design and it is very energy-intensive. Use it if you want, but the battery will run out very quickly.
There are programs that constantly want to update, even when network access is disabled. They work in the background and also consume a lot of energy. Here, decide for yourself whether you need them or not.
You can take another step like this. Go to the settings section, then to Data Transfer. There will be a list of applications that constantly use data transfer. Do you need all of them? Most likely, you will have to disable some of them or completely remove them. In principle, on some phones you can set a limit on the app's traffic usage. To remove unused applications, just go to Settings, then Applications. There you can disable the Press, Google Fit, Presentations, Docs, Google+, etc. applications. Attention! Do not disable the necessary Google services at the same time.
Have you probably noticed that some programs constantly give their notifications? They can also be disabled. Settings – Applications, then simply uncheck “Show notifications” (option for Android 4). For Android 5 you need to go to Settings - Sounds and notifications - Application notifications. Here you turn off notifications.
If you still need software updates, then on some phones it is possible to set the interval between updates. You can also disable the automatic synchronization feature.
If you decide that all these steps are difficult to do and just use some task killer or Android cleaner, then this will only bring satisfaction for the first 5 minutes. Next, the phone will try to launch all the programs and applications that were just closed, and this will drain the battery even faster. The freed memory is free only for the first five minutes. It is better to manually go through all the steps described, and then close all unnecessary applications from time to time. This is the only way to increase the battery life of the device and keep its memory empty.

Phone power saving features and battery life apps on Android

Almost all new generation phones have an energy saving function. Be sure to use this feature. At the same time, the processor clock speed is reduced, animation is removed, and unused processes are disabled. Sometimes turning on the power saving mode gives up to 2 hours of additional battery life.
There are various freely available apps that are designed to optimize energy saving and limit battery usage on Android. But these applications act like task killers, that is, they simply close unused programs, and then the system starts opening them anyway, which in any case leads to excessive consumption of battery resources.

Key Points You Need to Know

Use only the original charger to charge the battery. Even charging your phone via micro-USB using a tablet charger or via a computer's USB port is not recommended. Well, about the computer, then if you use a normal power supply with an honest 5 V and< 1 А, то подойдет. Если ваш смартфон рассчитан на зарядку 5В и 1,2 А, то при зарядке зарядным устройством, которое дает на выходе 5 В и 2 А количество циклов зарядки сократится. А если напряжение на выходе зарядного устройства будет 6 В, то количество циклов зарядки еще сильнее сократится.
You should not leave your phone in the sun or in the cold. In this case, the battery life is greatly reduced.

Articles and Lifehacks

Unfortunately, the battery is the weak point of many modern mobile devices. Why The phone began to discharge quickly included in, and what to do in such a situation? This is what our article will be devoted to.

Why did my phone start to discharge quickly?

On the one hand, manufacturing companies are constantly concerned about improving their smartphones. Technical characteristics are increasingly impressive, and this requires a certain processor clock speed and sufficient battery capacity. However, at the same time, devices are becoming thinner, and therefore they are often equipped with smaller batteries instead. The battery capacity is sometimes not enough even for 24 hours of operation.

However, many mobile devices initially meet their stated specifications, but over time they begin to discharge much faster. It is recommended to check if we have installed any new application that is consuming battery power, view statistics, etc.

Some users resort to more radical methods: they reset all settings of the device, thus cleaning it. After that, they completely discharge the smartphone, remove the battery for a few minutes and install it back. Without turning it on, the device begins to charge (at least 8 hours). At the end of charging, remove the battery again for a few minutes, install it back and turn on the smartphone. This procedure is called charge calibration.

Sometimes a sudden and sharp reduction in the battery life of our mobile device may be due to the presence of a virus or the installation of a program update. You can also try doing a full reset.

How to save the battery of a phone that is quickly draining?

There are actually many ways this can be done, and they are all very simple. So, if we do not constantly use Wi-Fi, Bluetooth or 3G, these modules should be disabled. By the way, owners of Android devices are recommended to try installing a program such as Llama. When you leave the house, it will automatically turn off wireless networks.

Every user should be aware that the display consumes the most energy. Therefore, it is advisable to imagine, or a smartphone, so that it does not drain the battery in vain. It is advisable to periodically reduce the brightness level, as well as disable automatic adjustment of this level.

You should not use animated wallpapers - instead, it is better to replace them with a static image. You also need to disable GPS navigation and automatic synchronization of accounts. The use of widgets has a very negative effect on the charge.

If your phone quickly begins to discharge, you need to start more control over the installed programs. It is also recommended to turn off vibration.
In conclusion, there are many special applications for Android devices that can save battery and extend operating time by up to 20-30%.

It helped me, what about you?

Rapid phone discharge is the main problem of all modern smartphones.

Agree, it’s annoying when, while waiting for an important call, your phone turns off. The most obvious solutions are, of course, to buy a new phone with a more powerful battery or start using the device more efficiently.

From this article you will learn how you can save battery power so that it lasts for the whole day and you do not have to interrupt an important conversation

How to properly charge your phone battery

Usually people charge their phone from the evening until the morning. This is completely wrong. Most gadgets are fully charged in just 3 hours. The rest of the time, the charger periodically recharges the device, keeping the charge at 100%. Due to this constant active mode of operation, the battery reduces its maximum capacity.

Why does my phone drain quickly?

1. Clogged charging port

Studies have proven that much more bacteria accumulates on the surface of a smartphone than on a toilet lid. That is why it is advisable to wipe the device periodically. Particular attention should be paid to cleaning the power connector area. Debris and dust get into this connector hole, which subsequently prevents the phone from charging fully.

2. Install bright wallpaper

People constantly look at their phone screen, checking the time, incoming messages or calls. By installing a black and white screensaver you will significantly reduce energy consumption.

3. Always carry the device in your hands

Heating and overcooling the gadget speeds up the drain of the phone's battery. Keep your smartphone in a place where it will not be affected by heat and frost. When the temperature is above +30 °C or the cold below –20 °C, try to take your phone out of your bag or pocket less often.

4. You always have automatic screen rotation turned on
Turn off Automatic Screen Rotation and turn it on as needed. The special sensor (accelerometer) that is responsible for this function consumes a lot of electricity.

5. Don't close application windows

All the apps that you simply minimized rather than closed continue to drain your battery while running in the background. That is why we recommend that you do not forget to close absolutely all windows from time to time.

6. Set screen brightness to maximum

Turn off automatic brightness adjustment and manually set the screen brightness to the minimum level that is comfortable for your eyesight.

7. Enabled vibration alert

This feature drains your phone's battery quickly. Try to turn it on only when necessary. Use normal sound mode or turn off the sound completely.

8. Incorrectly configured auto-lock

Set up your gadget screen to automatically turn off. Choose the best time for you to block. Thus, energy consumption will be significantly reduced, and even if you forget to lock the device, it will do it on its own.

9. Don't turn off GPS, Bluetooth and Wi-Fi

Disable these features if you are not using them at this time. Having GPS, Bluetooth and Wi-Fi turned on only contributes to wasting battery power.

10. Never turn off your phone

Experts say that you should turn off your phone at least once a week. This will extend the battery life.

11. Do not turn off the voice command recognition function

The battery of an Android gadget is greatly drained due to the “OK Google” command recognition function. The phone continuously scans for speech and sounds, waiting for you to speak, which drains the battery. Disable this feature via Google Now – Settings – Voice Search – “Ok Google” recognition.

Use the advice we give and your life will become much simpler and easier. Your battery will last until the end of the day, and you won't miss important conversations because your phone is dead!
