Why is my tablet charging fast? What to do if the tablet is quickly discharged. Why does a turned off tablet run out of power

Rapid discharge of Android gadgets is an actual problem that worries many users.

We continue our section of useful tips for Android device owners. We talked about what to do if a tablet or smartphone after some time has passed. It's time to touch on another problem that almost all owners of modern phones have encountered - the battery runs out quickly.

Let's start with the basic things that consume valuable battery power. There is a whole list of factors that are very easy to control.

The article was updated and supplemented in 2018.

Display Brightness

It is the screen that consumes the lion's share of the battery charge. Therefore, we advise you to reduce the brightness and abandon its automatic adjustment. This is especially true for budget and outdated devices.

Live wallpaper

Beautiful, fashionable, varied ... But they "eat" energy. Decide for yourself - beauty or battery life. The same goes for widgets, especially if they require internet access and update frequently, for example, weather or news.

Accelerometer sensor

In other words, the item "Automatic screen rotation". If it is enabled, then Android must be "on the alert" to flip the screen. Accordingly, energy is required. Read more about the operation and functions of the accelerometer.

Internet and communication

If you want your device to last as long as possible, you need to make sure that Wi-Fi, Bluetooth and mobile data are turned off. The fewer features included, the better. Especially quickly the battery is drained by 4G Internet (LTE) and active.

Background processes

Background processes are a phenomenon that both drains battery power and has a bad effect on Android performance. About how to disable unnecessary background processes, we wrote in. There is also an alternative way - an application, a review of which you can read at the link. It has flexible power saving settings and automatically optimizes system performance.

We also recommend disabling unnecessary native applications. Android device manufacturers often build adware, services, and games into the system that cannot be easily removed. These so that they do not send a notification, do not consume Internet traffic, do not slow down the phone, and do not drain the battery.

Exploitation

It is also recommended to use the device correctly. You should not allow your smartphone or tablet to completely discharge (even worse if they are not immediately charged). It is undesirable to charge gadgets halfway, and it is strictly forbidden to keep them in a warm place, as this adversely affects the battery. Be sure to follow the instructions for .

If the above tips did not help, it remains to wipe the device cache. To do this, go to and select the item "wipe cache partition". IMPORTANT: no other actions need to be carried out, otherwise there is a risk of resetting the gadget to factory settings or even turning it into a brick.

Other helpful tips on handling the battery is possible. This article explains how to save battery and how to handle the battery so that it lasts its allotted time without any problems.

Results and conclusions

In addition to all of the above, you need to know that battery energy is consumed by many factors. Among them, for example, vibration during a call, the volume of a melody and a vibration response when typing. Try to disable all unnecessary features.

If your smartphone or tablet runs out of power quickly, we recommend that you resort to these simple tips that should not be a hassle. If they don't help, do it. You need to understand that tips and tricks are relevant mainly for old and ultra-budget Android smartphones and tablets.

Are you interested in the question of why your Android tablet discharges so quickly and how to increase the tablet's operating time? This article is intended to help you understand the reasons for this. Following simple and even banal recommendations, you are guaranteed to be able to extend the operating time of the device without recharging. The article is aimed at beginners who have just started to master the Android OS, experienced ones will not find anything new here.

As you probably noticed yourself, the development of batteries is clearly not keeping up with the growing power and performance of devices on Android platforms. In total, there are three main things that consume the most energy, thereby reducing the life of your battery in the tablet:

1. Communication modules

The most inconspicuous "eaters" of battery power are communication modules that are included, but not always used: 3G, Bluetooth, GPS or Wi-Fi. If you constantly remind yourself to use the power management widget, thanks to which you can turn off all unused wireless services with one click, then you can significantly extend the life of your device without recharging. You can do similar operations on the quick access panel, which is next to the clock on the desktop. Some versions of Android have Airplane Mode. If you turn it on, all means of communication are cut off. Very comfortably.

2. Multitasking

Chip and at the same time the scourge of all tablets is the ability to run multiple applications at the same time - that is, multitasking. The problem is that when you start one application and then the second one without leaving the first one, the first one is not unloaded from the RAM. Actually, this is how multitasking works :) And only when there are a decent number of applications, the Android system itself will unload the “oldest” of the downloaded ones. It can be, for example, two or more running video players that quietly "working" in the background can very quickly eat up a significant part of your battery charge. Open all kinds of programs, readers, toys, file managers of various stripes, and so on. You can control open applications using special programs and utilities. And you may not be in control. Practice shows that all kinds of "taskkillers" only reduce the tablet's operating time.

3. Screen

Try not to work on the tablet with the maximum brightness of your gadget. As a rule, 50-60% brightness is sufficient for comfortable interaction. Maximum brightness is needed only in bright sunlight in order to at least distinguish something on the display. My advice is to set the brightness to automatic and don't worry.

Additional Energy Saving Tips:

BUT) Do not leave your tablet in the sun or near a heater for a long time The battery drains faster in warm weather.

B) Disable unnecessary apps/services- the factory applications often include applications that are not only useless, but also hang constantly in memory and are not cut off, they can be deleted by applications such as RootApp Delete and the like.

AT) Don't turn off your tablet- if you leave the tablet on for one hour and do nothing with it, and if you turn off the tablet for an hour and do nothing with it, then in the first case, the energy consumption will be less.

G) Optimize Wi-Fi- in latest versions Android now has the "Optimize Wi-Fi" option available, which is a good thing.

D) Disable sync- Android by default loves to keep everything in sync. This is useful of course, but not for everyone and not always. Go to settings and scroll down to account settings. There you can turn off auto-sync.

E) Turn off system sounds and vibration- when using an Android tablet, we are prompted to listen to notification sounds and vibration responses. This is also not necessary for everyone, and consumes energy. Disabled in sound settings.

AND) Use only static wallpapers— live wallpapers are very beautiful, but very expensive in terms of resources. So you will also win in performance. If you have an AMOLED screen, then the ideal option for you in general would be to put a black background instead of wallpaper. Seriously.

H) Don't use an external speaker- the sound will still be so-so, and the battery will be very strained. Use headphones.

I hope that I have somehow helped you to extend the battery life of your tablet. At least for an hour.

Articles and Lifehacks

Unfortunately, many owners of these gadgets are constantly faced with a similar problem. They have tablet drains quickly, and this greatly overshadows the joy of operating the device. Of course, it happens that it is simply used very actively. Our article will focus on the rapid discharge of the tablet for other reasons. Those who represent will certainly be able to list them.

Why is my tablet draining quickly?

It happens that the device is discharged, even when turned off. There are several explanations for this. For example, the user can simply put the tablet into Sleep Mode instead of turning it off. Even in this state, the device will consume a lot of energy, and sooner or later it will be discharged. To completely turn off, hold the corresponding button for at least 5-10 seconds.

Often we forget to turn off Wi-Fi, and therefore the battery is consumed very quickly. In addition, problems can be caused by certain programs or even the operating system. Perhaps the most frustrating cause of rapid discharge are technical malfunctions - for example, those associated with motherboard or battery. In this case, you should contact the service center.

Let's talk about crashes caused by software. Many users start noticing problems after installing a new application (or updating it). This can happen not only on Android, but also on Windows. You should be aware that device manufacturers themselves warn us that it is not recommended to install updates immediately after they are released - instead, it is better to wait for the end of testing. A good example is the Windows operating system.

By the way, most often the battery is discharged due to programs from third-party developers. For example, Skype consumes a lot of energy. If we actively use it, it is better to install an older version (for example, 4.2), and also disable the program when it is not needed.

What to do if the tablet is quickly discharged?

The thing that affects power consumption the most is usually shortening the life of the battery. The communication modules (Wi-Fi, Bluetooth, 3G), the display, as well as several simultaneously running applications consume it most actively. Those who managed to find out, probably already faced this problem.

So, if we do not use mobile Internet or Wi-Fi, we should definitely turn them off. In addition, you need to train yourself not just to hide, but to regularly close all unused programs. The fact is that when you start the second application (simultaneously with the first), the first one continues to load the RAM. This is how multitasking is implemented, and at the same time battery power is wasted.

You should also try to reduce the brightness of the tablet screen. 60% or even 50% will be quite enough. An increased brightness level is only needed in sunlight. You can also try automatic brightness control.

If the tablet is quickly discharged, it is quite possible that we have neglected other recommendations from manufacturers. So, it is not recommended to leave the device in the sun and turn it on and off all the time simply because we do not use it. It is also worth turning off system sounds, synchronization and vibration.

Animated wallpapers have a very negative effect on extending the working time. It's best if we replace them with a static image. Also, do not listen to music through the speakers without headphones.

Where to begin

Sooner or later, all owners of various electronic devices, mainly smartphones or tablets, are faced with the problem of quickly discharging the battery of their gadget. Some users immediately turn to service centers or stores, believing that the problem lies in some components, such as a battery. Others try to solve the problem by installing different firmware or trying to modify the installed software. Still others immediately begin to scold the manufacturer and change the device with the hope that this will not happen again. In this article, we propose to understand the issue and understand how to do the right thing if your smartphone or tablet is quickly discharged. Let's start with the main thing - before you panic and take any action, you need to ask yourself three questions:

1 How long should my device last? A day, two, maybe a week? What kind of work time do I expect from him?

2 How often do I use it? Every five minutes or once a day? What if I don't turn it off? Or vice versa, do not use?

3 What is the use case for it? Do I play games or listen to music? Or maybe I'm always on social media? What exactly do I use the most?

The answers to these simple questions will help us understand the situation and understand whether something really happened to our smartphone or tablet or if it is something else.

How long should an Android smartphone or tablet last?

First you need to understand that the operating time of the device depends on a huge number of factors, and not just on the battery capacity (this, by the way, is one of the most common misconceptions).

Factors that affect battery consumption:

1 Use case. The more tasks you set the device, and the more difficult these tasks are, the faster the battery runs out. If you play games with excellent graphics, watch videos, use the Internet or GPS, like to set the brightness of the screen backlight to the maximum - do not expect your smartphone or tablet to show autonomy records, usually with this mode of use it sits down in 3-5 hours.

2 The quality and quantity of applications used. Today, the profession of a programmer is more popular than ever. Everyone wants to write their own application, get into the top downloads and earn fame as a famous developer. In pursuit of these achievements, programmers write thousands of programs and add them to the Play Store or similar stores. However, not all users understand that the quality of written applications can be different, because. not everyone who wrote these applications are really experts, or want to benefit other people. A large number of applications has poor quality or some hidden features that obviously will not benefit your device. For example, the application code may have a bunch of errors that force the device to work constantly and prevent it from "sleeping", or have the functions of collecting and sending a large amount of statistical data to third-party servers. As a result, the processor will run at higher frequencies, drain battery power and constantly leak traffic with your personal data, which will lead to excessive heating and inefficient battery consumption. Quantity installed apps also greatly affects the time of work, a little lower we will explain why and invite you to verify this.

3 Technical condition devices. All things invariably break down and become obsolete, the same fate befalls electronic devices. Over time, the capacity of the battery decreases, some components may fail. As a result, battery life starts to decrease. The built-in software (operating system) can also accumulate errors that lead to unstable operation of the device, its freezes, slowdowns, and rapid discharge.

4 External circumstances. For example, these include weather conditions (at low temperatures, usable battery capacity decreases sharply; on a sunny day, the backlight should work at a higher brightness to improve readability) or the quality of third-party services and services (reception level cellular communication; Wi-Fi signal quality; correct synchronization of data with third-party servers).

5 Technical characteristics of the device. Engineering solutions may not always be successful. For example, if a smartphone has a large diagonal of the device, but a small battery capacity, then it will sit down in a matter of hours. But it is no coincidence that we put this factor in last place. In 99% of cases, all characteristics change proportionally (more screen or more powerful processor - more battery capacity), so the average operating time is always about the same. In addition, to technical specifications include the characteristics of the components from which it is made. The fact is that not all of them have the same energy efficiency and performance. The newer the device, the more energy-efficient and efficient components it uses. This can be easily seen on the example of a line of flagship smartphones and tablets. samsung galaxy. With each new generation, the screen resolution increases, the processor power increases, additional functions appear, but the battery capacity increases only by a small amount of mAh (by the way, why this happens, we will also explain below). However, the average running time does not decrease, but rather increases. In particular, this is due to the use of more energy efficient components (the size of the components is constantly decreasing, and with them the heating and power consumption).

Summing up: answer the question: "My phone runs out of battery for so many hours, is this normal?" very difficult, for this you need to collect a lot of information. To better navigate, we will indicate the operating time in the average mode (per day: a couple of hours of music, an hour of Internet surfing, a couple of hours in navigator mode, 40 minutes of calls, messengers or mail in moderation), this is about one to two days. But remember that everything is individual.

How to increase the battery life of your Android smartphone or tablet

Now let's see how we can eliminate the causes mentioned above, or at least try to reduce their impact.

1 If you honestly answered yourself the questions above and came to the conclusion that you do not let go of your smartphone or tablet, then we have bad news for you. It is impossible to increase the operating time with such use, since this requires a completely new type of battery, which mankind has not yet invented. But do not despair, there is always a backup option. In your case, this is the purchase of an external battery in which you can carry spare energy and recharge the main battery of the device. These batteries are available with different capacities, and you can easily choose the one that is right for you.

In addition, I immediately want to answer the frequent question why Samsung did not make a standard battery with a larger capacity. The fact is that not everyone plays games, watches videos or surfs the Internet. Most people use their smartphone moderately, do not load it with a lot of applications, and the standard battery is enough for them, for example, the author of the article uses a Galaxy S5 and it lasts for two days. If the standard battery had a larger capacity, firstly, the dimensions of already rather big devices would be much larger (you can’t put it in your pants pocket), and secondly, the price would also increase. That is why, with the help of additional accessories, we offer to increase the capacity exactly to the one you need.

2 Let's analyze what is important to know and understand when installing applications.

Every time you decide to install a new application, pay attention to permissions. Permissions are a list of what the app can do on your device once it's downloaded. The more permissions the application has, the more system resources it will use, and the more difficult it will be for the device to go into power saving mode (the so-called sleep mode), because the application can run in the background and will constantly wake it up, even if the screen of your gadget is turned off and nobody uses it. You can read more about permissions in our article.

Necessarily control the number of installed applications, because as we found out, each application has permissions, and if there are a lot of applications, then the permissions increase significantly. If there is an unnecessary application - delete it, do not leave it in reserve.

Try to choose those applications that are written by famous authors, downloaded many times and have a high rating. Of course, this is not a guarantee of stability, but it significantly reduces the risks. It is also useful to know that the functionality and stability of an application can not only improve, but also deteriorate with its updates. It often happens that no new applications were installed on the device, but suddenly it began to discharge quickly. The problem may lie in an unsuccessfully written update for some application.

To diagnose your device, you can use safe mode. It differs from the usual topics that only standard applications work in it, and all downloaded ones are disabled and have no effect on the system. If the problem disappears in safe mode, you can safely conclude that downloaded applications are to blame. However, at the moment there is no tool that allows you to find out exactly what kind of application it is, so they usually act like this: download the gadget in safe mode and check for a problem. If the problem is gone, then they load normally and begin to remove those applications that were installed or updated last until they find the culprit. By the way, you can try to do this test: boot your device in safe mode, note the time that it will work on a single charge, and compare it with the time it works in normal mode, we assure you, you will be surprised. You can read more about safe mode in our special article.

Also, the author of the article met user comments that pre-installed (embedded) applications are also to blame for the discharge. It is possible that there is some truth in this, but numerous experiments suggest that if there is an influence, then it is extremely insignificant. Moreover, the operating system is designed in such a way that the work of many applications depends on each other, and their thoughtless removal can only harm the device.

Nevertheless, it would be dishonest not to tell about all the possibilities, so we share with you "secrets": some of the pre-installed applications can be disabled so that they will not affect the running system, i.e. they seem to fall asleep. How to do this, you can see in this article. You can turn them back on if needed.

3 Now consider which of the components can affect the operating time of the device. There are two possible reasons:

The battery - its service life is designed for a certain number of charge-discharge cycles. In use, usable capacity
starts to decrease until the battery can no longer hold a charge. That's why every one to three years the battery needs to be replaced(depending on the intensity of use). You can purchase original batteries at authorized Samsung service centers, branded stores, as well as from partner companies. The required model can be viewed on the old battery.

In addition, there are several myths that are firmly entrenched in the ranks of users, so I would like to separately note the following: the battery can be charged as you like, you do not need to discharge it to zero, keep it on charge for 15 hours, and do not be afraid to use your battery when charging. device, nothing will happen to it.

The motherboard is the most important component of your device. It can have completely different damage, as a result of which the device can quickly discharge. Professionals are taught to understand these damages, therefore, if you are convinced that the problem is not in the battery or in something else, we strongly recommend that you do not experiment on your own, but contact any of our service centers in our article.

Change your mobile operator if the coverage area does not suit you :)

What other advice can we give? There are few of them, but they are also very important:

Disable auto-sync of added accounts or configure it selectively.

Synchronization is the process of transferring various data from a smartphone to a server and vice versa. This data can be anything: new contacts, music, mail, photos, achievements in games, etc. When you are not using the device, it is in "sleep" mode, in which power consumption is greatly reduced. Synchronization works in the background, so you may not even notice how it "wakes up" the device. If this happens very often, then the device can be discharged much faster, even if you do not use it.

If you have tried all the recommendations in this article except contacting a service center, but nothing has helped, then you need to do a factory reset.

Resetting the settings is the return of the device to the factory settings, which erases all the data, and with them the errors that accumulate in the device after active use. Factory reset is the best prevention against errors that occur over time in operating system and applications. This is especially noticeable if you use a smartphone or tablet after a reset without immediately downloading a bunch of other applications to it. And especially it is important to do a reset after the update software (firmware). Not everyone knows, but the firmware process on their own and in the service center is very different, which is why many people start to run out of battery just after the update. This does not mean that the update is bad, it means that it was not delivered correctly. Therefore, we repeat once again: be sure to reset after the update, this will greatly reduce the likelihood of various troubles with your gadget.

It is necessary to charge a smartphone or tablet based on the Android OS at least once every one or two days. The more often a user watches videos, browses social networks and chats on WhatsApp, the more intensively the battery is consumed. Every year the battery capacity decreases, and its action does not last long, it is discharged. What to do if the phone completely stops charging or quickly sits down? There is a solution: tips and instructions - further.

The tablet on Android does not charge: causes and solutions to the problem with the device

Faced with the case when the smartphone does not charge at all? This happens, because over time, any thing fails. This is the first reason for a breakdown that the owner of the gadget can come up with and which is very easy to check.

If everything is in order with the electricity in your house at the moment, the socket is working, check the operation of the charger itself. Some gadget owners leave the charger in the socket after use. This will sooner or later lead to its combustion. The wire from the charger may also be faulty, perhaps it was crushed by something, it is twisted or burned out. This is easily determined by its appearance.

Is everything in order with the charger and wire? Try to charge another gadget - ask a friend for a phone or use a tablet. If charging is normal, then the problem is in your smartphone. Let's figure it out.

The smartphone does not charge, although the charging indicator is displayed

Have you connected a working charger to your gadget for a long time, the battery icon on the screen of your smartphone or tablet is displayed as on recharging, but the percentage is not gaining? There may be several reasons:

1. Not a "native" charger is used. Indeed, manufacturers of some smartphone models (for example, HTC) welcome the use of only additional devices compatible with the gadget. At the same time, in some cases, a notification about slow charging and a suggestion to use a compatible charger will be displayed on the smartphone screen. Attempts to close the notification will only lead to its reappearance until the gadget receives the desired wire.
2. Another reason is that the charger does not provide enough power for a smartphone or tablet. A smartphone can consume 500-600 mA, and the charger can provide a current of 50-100 mA. If you understand electronics, use a multimeter to measure the current strength. Otherwise, try another charger for comparison. Surely you still have extra chargers from old phones or other gadgets.
3. The third reason for this behavior is that battery consumption is faster than charging. This happens when a power hungry application is running - social network, video display, photo editor. Try exiting all apps while charging, turning off wi-fi or mobile data, and just to be sure, turn off the gadget altogether and check if the battery level rises.
4. The same applies to the use of applications whose task is to save the level of charge. Installing unverified applications of this type causes conflicts with the device, which is why the charging circuit is violated. To check, remember the percentage of the charge level, turn off the smartphone, turn it on again after a while and check if the percentage has increased. If yes - find such applications and remove or disable them.
5. Alternatively, the contacts of the micro-USB connector itself (the end of the charger that is inserted into the smartphone) could be oxidized or clogged with dust. Dust could also get into the opening of the smartphone. In this case, you need to clean the connectors - this can be done with a toothpick with a small piece of cotton wool soaked in alcohol or a corner of paper folded into two layers. Just move along the smartphone connector, charger and inside the connectors. On cotton wool or paper, you will notice dirt. Cleaning the contacts often solves the problem.

The device does not charge via USB from the computer

Everything is in order with the contacts of the smartphone, the charger cable is normal - there are two options left. The USB connector of the charger itself is faulty or the same connector in the computer is out of order. If you are charging from a laptop, check if the laptop has turned off for some reason (for example, after installing updates and then turning it off) and cannot power the smartphone.

Try charging through a different USB port on your computer, such as the one on the back of your system unit.

The smartphone does not charge after being completely discharged

The battery is probably dead. Modern batteries are equipped with controllers, in which the processor has such a parameter as the minimum supply voltage level. If the device is discharged below this limit, the controller does not signal the charger. Try leaving your phone on charge for more than 8 hours, this may solve the problem.

Another way: use the “frog” recharge. This is a special device that helps to "reanimate" a dead battery. Remove the battery from the smartphone and clamp between the frog contacts, then connect to an electrical outlet. Hold for no longer than five minutes, then return the battery to the gadget and charge as usual through the adapter.

The same solution for the tablet, when it is completely discharged and no longer charges or turns on. If before that you did not keep it in the cold, then it's time to "revive" the battery in the way above (with the "frog").

The gadget stopped charging from the cigarette lighter

The reason is probably that your smartphone or tablet requires a different voltage to charge than is available through the cigarette lighter. This is typical for large smartphones called "shovels". If a output voltage on USB is insufficient, the phone will record the fact of charging, but this will not be enough to fill the battery. The length of the wire can exacerbate the problem. The longer it is, the greater the loss of current. Solution: Try a shorter, thicker USB cable.

Device shows charging but not charging

This can be seen when the smartphone is connected to a power outlet - its screen turns off and then turns on again, as if the charger had just been connected. The smartphone does not charge, but only loses battery power. The reason is in severe overheating or in a "non-native" charger. Be careful, an inexpensive low-quality charger can damage your smartphone.

Video: what to do if the battery is dead and the smartphone does not turn on

What to do when the device shows that charging is in progress

Device only charges when turned off

Again, we are looking for the root of evil in battery saving applications or in other applications that require access to the Internet. They not only prevent the battery from charging, but also discharge it very quickly.

Charging but not completely

It's all about the charger or insufficient voltage (when charging from the USB port of the PC), try connecting another charger and power the smartphone from the outlet.

Not charging more than 1%

The reason is that the battery consumption is greater than what comes from the charger. Try turning off your device. If it does not help, change the charger and try to power the battery from the outlet.

Doesn't charge until rebooted

Probably again some app is interfering with battery charging. After a reboot, the application is removed from memory and charging is restored. Try powering your smartphone by turning it off.

Discharges when off

In this case, some part inside the smartphone takes away some of the battery power due to a malfunction in its operation. Try inserting a different battery. If it is also discharged, then you need to carry the gadget to a service center.

The device is charging, but shows an incorrect charge value

The problem is mostly solved by rebooting the smartphone.

Why is the battery draining quickly on Android devices, what to do

As already described earlier, the fast discharge of a smartphone or tablet, in some cases even exceeding the charging speed, is the result of applications or an Internet connection. This often happens with no longer new batteries that can sit down in a couple of hours of not using the smartphone, just from the included wi-fi. Tip: turn off the network connection where it is not necessary and close energy-intensive applications: social networks, video broadcasting, games.

Charges and discharges quickly

There are two possible reasons: the battery has been overexposed in the cold (to do this, it is enough to carry the smartphone in a pocket of outerwear or in a bag) or the battery has worn out. Solution: put in a new battery.

The battery of the device takes a long time to charge and runs out quickly

Some smartphone owners who are faced with a similar problem are advised to clean the contacts of the USB connector of the smartphone itself or intervene more seriously, arm yourself with a screwdriver and slightly bend the bar inside the microUSB port towards the gadget display. If you are not sure of your actions, it is better to take the gadget to a service center.

Quick discharge of the gadget in standby mode

Some apps continue to run in the background even after you've finished using them and eat up a percentage of your battery. For the purity of the experiment, turn off network access, wi-fi, gps, 3g and check the charge level. Does he continue to sit down? Look for the culprit in the list of applications.

Smartphone's battery is running low

There is no consensus on the causes of this problem. Someone claims that the problem is in the type of battery. Li-Pon batteries hold a charge worse than Li-Ion batteries. Try changing the battery, but it's best to take the device to a service center.

The device began to discharge quickly after the update

Probably, some processes of the new firmware “freeze” or cause conflicts. The reason may also be a looping access to the device's SD card (for example, you were searching or processing photos or videos, the process freezes and continues to consume battery power). Try to remove the SD card from the phone and check the battery level without it. If the problem is not solved, then the only option is to return to the factory settings. Here you will need to copy all the data from the phone to the computer, make a backup and only then do a factory reset to save all personal data.

A new device from the store runs out of battery quickly

This happens because usually new smartphones and tablets are not fully charged. After the purchase, many users do not wait for a complete discharge, but put on recharging and so on all the time. This leads to the fact that the smartphone, as it were, “remembers” the maximum battery level and the difference until it is fully charged, and in the future it always recharges exactly by this difference. This leads to the fact that the battery capacity decreases, and it quickly sits down. Experts recommend that you always wait until the device is completely discharged, and only then charge it several times. This "trains" the battery.

How to Check Battery Status

Inspection of the outer surface

You can get an idea of ​​the health of the smartphone battery by its appearance. If the battery is not sewn into the device, pull it out and inspect it. Usually you can immediately see that the battery is swollen - if you look at it from the side, the top or bottom surfaces may be uneven, but slightly semicircular. It speaks of swelling. Metal contacts can be affected by corrosion, and green or whitish spots can be clearly visible on the battery. All these are signs of mechanical damage to the battery and the reasons for its failure. In no case should you put such a battery back - the electrolyte from it can spill onto the inside of the smartphone and finally lead to a breakdown. Replace the battery and discard this one.

It happens that the battery overheats or supercools and also begins to swell. It's hard to tell by eye. Do a little test - place the battery on a flat surface and rotate it. A one-piece battery will not spin easily. Rapid rotation indicates swelling.

Software Settings and Applications

You can enter system settings and view the battery status. Dial the special code *#*#4636#*#* on your phone, then select "Battery Information". In the list that opens, detailed parameters of the smartphone battery will be displayed. If the code didn't work, download the dedicated app from Play market.

One of the simple and functional applications for assessing the condition of the battery is "Battery - Battery". The application is free and available in the Play Market. The program weighs a little and almost does not waste the energy of the smartphone. After starting, the indicators of the sensors will be displayed on the screen.

Another small app with similar options is 3C Battery Monitor Widget. Launch the app to see the metrics: temperature, battery capacity, consumption, voltage, and a general health score.

Sometimes access to the system settings is necessary because the main battery indicator is displayed with a question mark, which makes it impossible to determine the charge level. In this case, you will need to roll back the updates to the previous version, but this may not solve the problem either. Often a question mark indicates a faulty battery and the need to replace it. Take your smartphone to a service center or buy a new battery.

How to charge an Android device if the socket is broken

Of course, it is better not to bring the smartphone to such a state, but if this still happened, there is a way out. The first thing to remember - do not try to fix the nest yourself if you do not have knowledge of microelectronics. Leave it in the hands of experts. Until then, you can try to charge it in one of the following ways.

Charging via universal charger

We have already mentioned the "frog" - this device will help you charge your smartphone directly, without using a cord. Remove the battery and clamp between the "frog" terminals. The disadvantage of this method is that such a device can be expensive and, in exceptional cases, “kill” the battery. This doesn't happen often, but it's possible. In addition, the phone will be turned off the entire time of recharging, which means you may miss some call.

This radical way to charge your battery is only for you if you're into electronics. You will need electrical tape and a utility knife. Follow instructions:

1. Few people pay attention to the fact that new devices with the Android OS should be charged according to a special method. Consultants in the store sometimes warn about this, but such information is quickly lost sight of. The first two or three times after purchase, a tablet or smartphone must be discharged until it turns off on its own and only then put on recharging. Many neglect this, connecting the charger as soon as the charge level drops below 50%. The smartphone remembers the difference up to the full battery level and next time replenishes energy by exactly the same number, regardless of the level of discharge. So the battery quickly loses capacity, and smartphone owners are perplexed why it quickly sits down. Conclusion: the battery needs to be “trained”, that is, the charge level controller located in the battery needs to be calibrated.
2. Another tip - do not leave your smartphone on charge overnight. Of course, it will not burn out - modern devices can suspend the flow of energy when the battery is fully charged. But heating still occurs and who knows at what point it will lead to a failure. This is especially true for phones in cases.
3. If possible, use only the "native" charger. Application of Chinese chargers with poor quality can also lead to overheating and failures.
4. After the first few charges to 100% and discharges to zero, try to keep the charge level no higher than 80%, but not lower than 20%. This will help save the battery. It is better to recharge the gadget with short connections than once and all the way.

Each owner of a smartphone with Android OS should be attentive to his device, “train” the battery and keep several spare chargers on hand. Then it will be easy to deal with any problem with the help of simple instructions and the available devices, and the device will last for many more years.
