A smartphone is a versatile device that allows you to solve a large number of different tasks with minimal cost time.

In the same time this device due to the specifics of its work, a lot of energy is needed, therefore the capacity of the battery is a very important factor. But it often happens that the charge is spent very quickly for no apparent reason.

Today, almost everyone has devices such as smartphones. All well-known brands offer fairly high-quality products. But even she tends to break.

To understand why a smartphone is quickly discharged, it is necessary to observe exactly what factors affect the duration of its operation. You can experimentally fix the problem.

If for some reason you can’t find the problem, then you should try standard ways, allowing to solve the problem of the type in question.

Causes and solutions

Most often, gadgets on the Android operating system lose their battery charge very quickly due to:

The reasons for the rapid discharge indicated above are quite typical; to eliminate them, it is not even necessary to perform any complex manipulations.

Live wallpaper

A working screen, as well as various processes taking place on it, seriously affect the processor load. The larger it is, the faster the battery energy is consumed. And sometimes the discharge rate due to the work of these wallpapers increases by a whole third.

Live wallpapers can be of two types:

In both cases, you can resolve the situation quite simply without outside help.

If live wallpapers are set to standard, then you can do the following:

• open "Settings";
• click on the "Screen" item;
• select the "Wallpaper" section;
• activate standard wallpaper without animation.

If it is set special application, which creates animation on the desktop, you just need to remove it.

This will require:

Accelerometer sensor

The gadgets in question today are real telecommunications combines, stuffed to the eyeballs with a variety of functions that can solve various problems.

Almost every device has an accelerometer, it allows you to measure the acceleration, as well as the position of the device relative to the ground. But its use increases the load on the processor.

It is because of this device that the battery can be discharged very quickly.

To turn off this sensor and reduce the discharge rate, you must:

Close background apps

Right after the screen CPU(especially if it's multi-core) is the most power hungry device. Since data processing requires maintaining a high voltage on the bus and inside the CPU itself. Therefore, in the presence of a large number of simultaneously running applications, the battery energy will decrease quite quickly.

To close various kinds of running programs, you must:

• open the "Settings" menu;
• select "Applications";
• activate the "Working" section.

In the list that opens, you should select which utilities are not required at this particular moment. Then click on the desired icon and stop. To do this, there is a special button on which the inscription "Stop" is located. Sometimes some products from third-party developers consume up to 50% of the stock battery.

Brightness setting

The display has the highest consumption. This component, regardless of its type, always emits light during operation, as the backlight works. It is thanks to her that the user can easily distinguish in the dark everything that is on the screen. But the brighter it is, the faster the battery is consumed.

In many cases, a problem such as a rapidly draining smartphone battery can be solved by simply reducing the brightness of the display.

On all devices under control operating system Android can do it like this:

• with your finger, lower the working screen down;
• we find at the top of the menu an icon called "Brightness";
• a long slider will open, moving which you can adjust the strength of the glow.

By making the brightness a little less or turning it down to zero, sometimes you can save up to 100% of the battery charge. You should also always turn off the display if you do not need to use it.

Communication setup

In some cases, to save power in the device, you simply need to disable some communication protocols. For example, GPRS/3G/LTE. Since it is precisely because of the working modules that support the connection of these types that the battery can literally melt before our eyes. Often it is enough just to turn them off - this will allow you to connect the gadget to the network much less often.

The operation of various communication modules is disabled quite simply. You just need to open the taskbar, which is located at the top of the screen, and click on the corresponding icons - the highlight from under them should disappear.

Turn off wireless technology

Often, immediately after the purchase, the happy owners of the phone cannot understand what is wrong: the new battery is losing its charge right before our eyes. At the same time, any visible reasons not for this: the screen brightness is at the very minimum, only the most necessary background applications work.

The secret of this behavior may lie in the fact that the device is simply activated all at the same time or some individual wireless technologies connections.

These include the following:

• bluetooth;
• WiFi.

Wi-Fi consumes battery especially strongly. To disable these technologies, you should open the settings and check the switches with the corresponding signatures. They should be in the off position. Otherwise, you should disable them.

Turn on "Airplane Mode"

All gadgets running the Android operating system have a special profile called Airplane Mode.

When activated, the following modules are disabled:

• UMTS.

At the same time, Wi-Fi and GPS continue to function. An important feature of the mode of this type is that during its operation the charge consumption is significantly reduced. Turning it off is simple - just press the "Power" key and select the appropriate menu item

2G network

Most in a simple way get rid of the rapid consumption of the battery is to use the mode in which communication is carried out through the 2G protocol.

It's very easy to do this:

Other

Also, the phone can lose battery power very quickly due to hardware problems. This may be a common factory defect in the battery, motherboard, or other parts of the smartphone. Sometimes there are problems with the connector special device to charge, or the mains voltage is not high enough or too low.

Smartphone drains quickly in standby mode

Sometimes the device can be discharged very quickly in standby mode. The culprit may be damaged motherboard where there are leakage currents. To determine the presence of this kind of defect is possible only with special equipment.

If you suspect such problems, it is best to contact an authorized service center.

Save battery

If all the above methods of dealing with a falling battery charge do not help, then you can try using special utilities:

EasyBatterySaver is a utility that allows you to increase the duration of your smartphone by 5 - 20%.

It also has the following additional features:

• allows you to fully charge the device;
• makes it possible to restart the gadget as quickly as possible, kill its tasks;
• maybe in automatic mode deactivate Wi-Fi, Bluetooth, and other processes.

BatteryDr.Saver

Battery Dr.Saver is a utility in which you can select the optimal mode of the used battery. It makes it possible to reduce the charge consumption to the very minimum. But the most important advantage of this application is the ability to save up to 50% of the charge in standby mode, as well as increase the duration of work without recharging.

Update Firmware

Sometimes a simple firmware update is enough to resolve the type of problem in question. This is especially true for devices running on very early versions of Android.

This process does not take much time, all you need is a good internet connection and a fully charged battery.

Battery problems on smartphones Android control quite widespread. However, in most cases they are relatively easy to deal with. It is only necessary to observe the specific device as closely as possible and check what exactly affects the duration of work.

If your smartphone's battery drains too quickly, don't worry, you can probably squeeze more life out of it by optimizing some of your phone's settings. As part of the article, we will tell you what to do when the battery runs out quickly on Android.

Reasons why the phone drains quickly

There are two main reasons why your phone's battery drains quickly:

• hardware - battery wear due to prolonged use, overheating, disruption of the power controller;
• software - flaws in the firmware, "crooked" software, unreasonable operation of data transmission modules, etc.

It is very difficult to eradicate faults from the first category, you will probably have to change the battery or go to a service center. Yes, you can distort the contacts at home, pull out the battery, but an oversight will lead to irreversible consequences.

With the second group, everything is easier, there is a lot in your hands, and we will tell you what to do if the battery runs out quickly on Android.

What to do when the phone runs out of power quickly?

Let's discuss ways that you can follow to quickly reduce your energy consumption.

Check which apps are using the most battery

Tap "Settings - Battery" to see a list of all apps and how much power they use. If an app you don't use often is eating too much, then consider deleting it, freezing it, or stopping it.

Remove unwanted software and ads

Programs often leave their services hanging in the background, they load RAM and load the processor, reducing the operating time from a single charge. Remove unnecessary applications, especially unnecessary instant messengers and everything that tries to connect to the Internet. In order to get to the uninstall menu, go to "Settings - Applications".

It often happens that advertising embedded in software causes the smartphone to actively discharge due to additional downloads of material from the network. To neutralize it, use an ad blocker, such as Adguard. You can download it from the Play Market.

Never use task killers (CleanMaster)

Despite the popularity of killer apps for Android, they cause great harm to the phone, as they unload the necessary components and services from memory, which start again, forcing the processor to work at higher frequencies. And it goes on forever.

Even through the multitasking window, it makes no sense to constantly unload processes. Except for the ones you rarely use. Android has already learned how to independently regulate the work of background activity, it makes no sense to help it with this, since Doze does a great job.

Uninstall unnecessary widgets from the home screen

Widgets drain your battery due to constant syncing and refresh animations. They also litter the RAM. It's not worth getting rid of all the widgets, but try to remove the ones that are not so important.

Enable Airplane Mode in Low Signal Areas

Smartphones use a lot of power when trying to connect in areas with low signal strength. So if you can't get a stable network connection, turn on airplane mode. To do this, turn the curtain down and tap on the aircraft icon.

If there is no icon, then go to "Settings - Wireless networks".

Disable data transfer when not in use

The mobile Internet, especially over LTE, arranges a total genocide of the charge. Try to turn it off if possible. This will greatly reduce standby consumption and give at least one additional hour of screen activity per day.

Disable GPS when not in use

GPS is the heaviest module on the battery (probably you noticed this when using Google maps). This is another component, in addition to 4G, mercilessly killing charge percentages. Therefore, never forget to deactivate it in your smartphone.

Also go along the path “Settings - Location - three-dot icon - Search”, and now turn off both items that are responsible for constantly searching for Wi-Fi and Bluetooth.

Turn on power saving mode

For Android 5.0 and later, this function allows you to increase the time battery life. For example, animations will be removed, most background syncs will stop, and location services will be disabled. The operating system suggests activating this mode when it reaches 15% charge in order to extend the operating time.

Lower the screen brightness

If you are using Android 5.0 or later, open Settings - Display and turn on " Automatic brightness”, which will allow the display to adapt to lighting conditions, ensuring that the matrix is ​​never brighter than necessary.

But if your battery is in a "deplorable" state, manually dimming the screen is good method extend autonomy until you get to charging.

Remove live wallpaper

The system offers the flexibility to personalize the home screen, but try not to overdo it and give up live wallpapers. They load the processor and RAM. It is better to give preference to a static picture on the desktop.

Reduce screen timeout

You can save a lot of battery life by reducing the amount of time the display stays active. Open "Settings - Display" to set the screen timeout, for example, 30 or 60 seconds. It seems that this is not very important, but in this way you will significantly reduce energy consumption, because the matrix (especially IPS) consumes it the most.

stop vibration

For the operation of the vibration motor, power is required, not very much, but still. To turn it off, go to "Settings - Sound - Other sounds" and uncheck "Vibration feedback". Also turn off vibration in your keyboard settings.

Keep your phone cool

According to research, the condition of a battery deteriorates greatly when it gets too hot. Do not leave your phone on the dashboard of a car on a sunny day, on a windowsill, under a laptop cooler, etc. The most important thing is not to let the “bank” heat up to 45 ° C. Monitor the heating during games using the AIDA64 utility. Usually, heating under load is regulated by throttling (the process of lowering processor frequencies to reduce heat), but it's better to play it safe and control the heat dissipation yourself. It is very important.

Always download updates

Install firmware and application updates. They are often aimed at improving energy efficiency.

Keep the charge between 30% and 90%

The best way to keep a battery running for a couple of years is not to discharge it below 30-40% and never charge it above 80-90%. This is far from always possible, but at least try not to put the gadget on charge overnight, so that when it is charged, it does not stand for 4-6 hours connected to the outlet at 100%. All this reduces the capacity of the battery.

We understand that it is possible to argue “who serves whom: the phone is yours or you are the phone?” Therefore, you should not obey the requirements of the battery so much, but strive to discharge at 0% as little as possible and leave it overnight.

Let the battery drain occasionally

Calibration - full discharge, and then charging your phone's battery to 100% every three months helps maintain its capacity.

Destroy viruses

Malicious programs sometimes get into the system and affect so that the device starts to sit down faster. To demolish them, check the list of applications for suspicious software. Also download from the app store antivirus solution, for example, Kaspersky, run and let it scan the operating system. After that, remove the dangerous components.

Change firmware

A rather radical method, which sometimes works best, because on stock firmware gadgets sometimes discharge too quickly. Read about the available custom, find out which is the most stable, holds a charge well. After carefully install the assembly. Often firmware based on Lineage or AOSP take care of the charge, so over time, many decide to switch to them from official shells.

Reset to factory settings

If nothing helped, the phone began to consume unreasonably much, do hard reset to return the system to its original state. Go to "Settings - Backup and reset - Factory reset". Read the warning, backup the data that will be deleted and start the process. This will help mitigate system failures that sometimes happen.

Solving hardware problems

Now we will touch on the topic of solving hardware problems.

Google Battery Calibration

We bring to your attention the battery calibration method proposed by Google Corporation. In some cases, it helps to normalize the behavior of the battery and the power controller, which began to incorrectly determine the capacity.

1. Connect a completely discharged mobile phone to the power supply and charge it in the switched on state for at least eight hours.
2. Unplug it, turn it off and charge it for another hour.
3. Turn off the device, start it, use it for one or two minutes.
4. Unplug and plug back in for an hour.

The method looks strange, but it allows you to reset the controller statistics and adjust the real capacity to software algorithms for calculating it.

Use only original charging components

This is important because some devices with fast charging do not perceive the connection to third-party power supplies. Also, too much power, for which components are not sharpened, can harm the battery, and it will start to sit down faster.

We have described the most important methods. Not all of them can be met, but the purpose of this article was also to explain to you what affects the discharge the most, so that you, knowing the reasons, could independently develop an energy-efficient and comfortable user profile for the device.

The first mobile devices were designed to make calls and send SMS. But their time has passed, and "smart" assistants have come to replace them, which make life easier for us every day. With their help, we get access to the Internet, use a navigator, listen to music, book a table in a restaurant, buy tickets for the concerts of our favorite artist, read books while we get to work.

Such multitasking affects the rate of battery drain. Agree, we will not like it at all if the smartphone turns off at the very moment when, for example, we buy movie tickets.

1. Screen (reduce brightness, remove animated screensavers)

A bright, colorful, juicy smartphone screen is spectacular, but you have to pay for all the pleasures. And in this case, we pay with the fact that the battery of our device will be discharged much faster. Set the Brightness slider to about half the scale (this can be done by going into the settings). Such a simple action will not only save battery power, but also take care of our eyes, relieve unnecessary stress.

You can install a special sensor on your smartphone, and the gadget will adapt to the lighting around us, adjusting the brightness of the display, for example, it will increase it if we are in the sun. Yes, such a sensor also consumes battery power, but this consumption is negligible compared to how much charge a bright display consumes.

The next moment is animated intros. Yes, they also look spectacular, but again we waste a huge part of the battery. It is better to install wallpapers on the display instead of such screensavers dark colors(dark pixels do not require power).

Try all of the above to reduce the standby time: so the smartphone screen will go out faster if we do not use the device.

2. Sensors (GPS, NFC, vibration signal)

So, constantly working geolocation consumes a lot of battery. We turn it off in the phone settings and turn it on only when necessary. The fact is that a device with GPS turned on constantly checks with the satellite, which entails battery consumption. And such a function, you see, we do not need every hour.

Majority modern phones equipped with an NFC module. It is needed to transfer encrypted information to short distances. For example, for payment (instead of a plastic card). Often this module not required by users. Therefore, we also turn it off.

Separately, let's talk about such an addition as a vibration signal or vibration response. You touch the screen, and the device vibrates back to you. At first, of course, you can amuse yourself with such a function, but keep in mind that each touch will discharge your device. Indeed, to create vibration, a small motor is sewn into the phone, which must also be powered by something. Our advice: turn off the vibration feedback to save battery!

3. Applications and widgets

Let's be honest, few of us use all the applications contained in our mobile devices. Conclusion: we delete those that are not in demand. So with one shot we kill two birds with one stone: we save battery power and increase the speed of the mobile device.

Some of installed applications even in sleep mode, they work hard: they send notifications, play sound even in the background. As a result, the battery drains faster.

Keep in mind that when you uninstall an app, you simply close the app from the recent menu. There is special program, which helps close all applications at once. It is called Super task killer. This action removes unused applications from the phone's memory. If you need one of them, find it and it will start downloading again.

If you do not want to search and install the specified Super program task killer , we have good news for you: most mobile devices are equipped with a function to close unused applications by default. To do this, we enter the "Settings", look for the item "Applications", select the service that we want to close. Click on "Forced stop". The phone may warn you that your actions will cause the application to work incorrectly, despite this, click "OK". We repeat the described steps for all applications that we decided to close.

4. Mobile communication, Internet, Wi-Fi

When leaving the walls of your home, do not forget to turn off Wi-Fi. If you leave this module running, your mobile device will constantly try to find a network to connect to. And this entails battery consumption.

The same applies to data transfer. If you are on the road and the network is interrupted, better internet you can turn it off completely (most likely, you still won’t be able to use it qualitatively). The fact is that the antenna of the mobile device will constantly look for and try to keep the signal. The more connections and disconnections occur, the faster the device will be discharged.

Let's stop and on the high-speed Internet. The new generation of 4G connectivity really has high speed. But not all operators mobile communications have 4G coverage. If your smartphone is set to default like this network connection, and you will be in a 3G coverage area, for example, then your smartphone will constantly look for the default 4G. Such a search reduces the life of the device.

5. Saving the battery itself

In modern mobile phones installed lithium batteries. Their service life varies from 1 year to 3 years (depending on the quality of operation). If the battery life is exhausted, it will sit down in a few hours. And there's nothing you can do about it, you'll have to buy new battery. Be aware that even with proper use, a new battery will lose up to 30% of its original capacity in the first year of operation. Often, a swelling of the battery leads to the replacement of the battery, mechanical damage or overheating. The use of such devices is strictly prohibited! They can damage the device itself. Such batteries are often found in Chinese mobile devices, especially counterfeits of well-known brands. And some models are initially equipped with a battery with a low capacity. Therefore, when you come to the store for a new smartphone, carefully study it. specifications, consult with the seller. Unfortunately, it is simply impossible to artificially extend the life of the battery.

6. Applications to extend the life of the phone

Opinions about such applications are twofold, let's say right away. Some experts argue that such assistants can really optimize the performance of your mobile device. They can be found in the shop Google Play and they are completely free. Let's talk about a few of them.

• Smart Quick Settings - free app aimed at optimizing the performance of your mobile device;
• Super task killer free is a program that can close all applications with one touch.

Some experts argue that such programs do more harm than good, and they should not be trusted, and it is better to perform all operations to optimize the operation of your mobile device manually.

In conclusion, we say that manufacturers modern smartphones already equipped with a power saving mode. It automatically adjusts all device settings in such a way that the battery charge lasts as long as possible.

Try to treat your phone with care: do not drop it, do not break it. Such breakdowns and damage lead to malfunctions in its operation as a whole.

Winter is ahead, we all warm up, but we can’t insulate gadgets. Meanwhile, most of them are not adapted to sudden changes in temperature. So during the cold season, while outside, try not to use your mobile device. Be patient until you get to your home, office, or at least public transport.

The problem of too fast discharge of the battery (battery) is faced by almost all users of mobile gadgets. The problem occurs gradually and goes unnoticed for some time, but one day the owner notices that the battery life of a smartphone or tablet has almost halved. If you do nothing, it will decrease further - until it becomes impossible to use the device. And one day the device will not turn on at all.

Let's talk about why the battery on Android devices runs out quickly and how to extend its life.

Reasons for fast battery drain

• The actual battery capacity of the smartphone or tablet is lower than specified in the specifications.
• Battery capacity has decreased due to normal wear and tear.
• Temperature external environment— below +5 ⁰C or above +30 ⁰C.
• Screen brightness set too high.
• Resource-intensive features included: GPS, NFC, Bluetooth, etc.
• Long distance to base station mobile operator.
• Power is consumed by apps and widgets running in the background.
• Frequent switching on and off of the device.
• Mobile virus infection.
• A malfunction of the operating system or hardware, as a result of which individual resource-intensive functions or the device itself are not turned off.

Battery capacity is lower than in the passport

The discrepancy between the actual battery capacity and the indicator indicated in the passport of a smartphone or tablet is more common than you think. It's just that very few users dare to double-check it. Most people trust documents, as well as program indicators, which also do not always display reliable data.

The reason for the discrepancy between the actual information and the nominal one does not always lie in the deception on the part of the manufacturer or seller (although this also occurs), it is just that lithium power supplies lose their capacity during long-term storage. If you bought a device released a year ago, even with proper storage, its battery has become less capacious by 2-6%, and with incorrect storage (that is, with a charge of up to 100%), by as much as 15-30%.

To calculate the actual capacity of the battery, chargers and dischargers, like iMAX, or home-made arresters complete with a multimeter or USB tester are used. Accurate indicators are determined during the discharge of a fully charged battery.

If your phone's battery capacity is less than advertised, it means that it will drain in a shorter time than expected. And, alas, it is impossible to influence this.

Capacity decreased over time

Battery wear becomes noticeable after 1.5-2 years of using a smartphone or tablet. But it can come earlier if:

• often and for a long time use the device at low and very high air temperatures (the most favorable for the operation of lithium batteries is room temperature);
• allow a discharge close to 0%.
• charge the device near heat sources;
• store an unused battery at 100% charge at high temperature environment(for storage, the optimal charge level is 40-50% and the temperature of the refrigerator);
• charge the battery more high voltage and currents than provided by the manufacturer (the required level of current and voltage is indicated on charger, which was sold bundled with the gadget).

Frequent short-term recharging, contrary to popular belief, does not harm the battery. A much greater influence is exerted by the current with which it is charged. Lithium batteries are preferable to charge with low currents, although this takes longer.

If the battery capacity of your device has decreased due to wear and tear, the only solution is to replace the battery with a new one.

Using the gadget in the cold or heat

When using a mobile device in adverse temperature conditions (up to +5 ⁰C and above +30 ⁰C), the battery discharges much faster, but at a temperature close to room temperature, its capacity is immediately restored to its original level.

If you do not do this too often, the battery will not wear out soon, but for calls in the cold it is still better to use a headset and keep the phone in a warm pocket.

High screen brightness

The screen of a mobile device on Android is the main consumer of energy. The brighter it is illuminated, the faster the battery drains.

The use of adaptive backlighting, which changes depending on the ambient light, helps to reduce battery consumption (only available on devices equipped with a light sensor). To turn it on, check the "Auto" box in the screen brightness settings. And so that the screen does not remain on when you are not using the gadget, set it to go to sleep after 30-60 seconds of inactivity.

Resource intensive features

The following active energy consumers after the screen are:

• geolocation;
• live (animated) wallpapers;
• NFC and Bluetooth;
• mobile Internet (3G, 4G).
• WiFi.

If they are all used at the same time, even the most capacious battery will run out very quickly, so if possible, turn off what you do not use.

Unstable cellular connection

You may have noticed that when you stay for a long time in places where the phone does not pick up the signal of the operator's base station, for example, outside the city, the battery is discharged faster than usual. This is because it takes more energy to maintain an unstable, dropping connection.

The battery will drain faster even if the problem is only with one of the two SIM cards. To save the charge, it is better to turn off such a SIM card for a while.

Apps and widgets running in the background

Many Android applications and widgets, after installation, prescribe themselves to autorun and work in the background all the time while the device is turned on. When there are many such applications, the device not only discharges very quickly, but also noticeably slows down, so autoloading should be kept under control and allowed only for those programs that need it (antivirus, optimization tool, utility utilities, instant messengers, etc.).

Unfortunately, there is no autorun control function for user and system applications in Android. But it becomes available after receiving root rights(superuser) and installing special utilities on the device, such as:

• BootManager and some others

There are utilities that allow you to manage autoload without root rights, but they do not work on every gadget and not always correctly.

Applications that the user himself launched, but after they were no longer needed, he forgot to close, can also consume battery resources. The accumulation of such programs not only loads, but also heats up the processor, and from it, in turn, the battery heats up. And when heated, as we know, the phone's battery runs down very quickly.

Control over processes that actively consume energy is also best entrusted to special utilities. For example, the following:

• Power Battery, etc.

By the way, the capabilities of most of them include cleaning the system from junk files, CPU cooling, charging optimization and a number of other tasks. To keep the device in order, it is advisable to use one of these utilities constantly.

Frequent reboots and turning on/off the device

Wanting to conserve battery power, some users regularly turn off their mobile gadget. Sometimes even several times a day. This is another reason why the battery drains too quickly, since when the device is started and the operating system is loaded, the energy consumption is close to the maximum.

While you are not using an Android smartphone or tablet, you should not turn it off completely - just turn off the screen, complete resource-intensive tasks, disable communication functions (Wi-Fi, GPRS, 3G-4G Internet, GPS, NFC and Bluetooth), background data transfer, sensors and vibration motor. To do this, most mobile gadgets have a power saving mode, the power button of which can be located in different sections of the settings (parameters) menu.

Mobile virus infection

Malware that attacks Android devices does not always operate openly. They often carry out activities that are invisible to the user, and the only signs of their presence are devastated accounts and very fast discharge batteries, including in standby mode.

Exclude hidden viral infection follows for any non-standard behavior of the gadget, for example:

• The phone or tablet wakes up without any action from you.
• The device is warm when it is in sleep mode.
• On the device, without your participation, Wi-Fi modules, geolocation, mobile Internet and others. Or they can't be turned off.
• In the list of outgoing calls and SMS appeared unknown numbers, and in the browser history - views of sites that you have not visited.
• An application has appointed itself as a device administrator without your knowledge.
• For unknown reasons, Google Play antivirus and other security applications have stopped running.
• Some system functions have stopped working.
• The volume of network traffic of the device has increased for no reason.

System or hardware failure

Some PC and laptop users have encountered such a problem as incomplete shutdown of the computer, when the screen goes blank when the operating system is shut down, but some devices remain active - the cooler continues to rotate, indicators are on, etc. Exactly the same problem occurs on mobile devices, it's just not so easy to notice, because there is no cooler on smartphones and tablets, and the indicator only shows the charging stage. With such malfunctions, the device essentially remains on all the time and, accordingly, even in the “as if off” state actively consumes battery power.

The causes of such problems can be crashing applications, viruses, operating system errors and a malfunction in the hardware of the device (including connected devices - memory cards, SIM cards, etc.).

The only symptom that allows you to suspect an incomplete shutdown of the device is too much battery consumption at a time when it should be minimal. And to make sure if this is really your case, just remove the phone (tablet) cover and check the processor temperature with your fingers. If the device continues to work after turning it off, its processor will remain warm. Sometimes in this state, the case of the device heats up slightly, but sometimes it does not - it depends on its design.

What in such cases can the user do without contacting the wizards:

• Remove applications installed before the problem occurred (if you were able to fix the time it started).
• Run an antivirus scan.
• Disconnect all connected devices.
• Reset the system to factory settings.
• Remove the battery (if it is removable), hold down the power button for 20-30 seconds and replace the battery.
• Flash the device with a known working firmware.

After each manipulation, check the gadget by turning it off. If the problem persists, you will have to take it to a service for repair, since the malfunction will not disappear on its own, and the battery will run out of its resource much faster than during normal operation.
