Reasons for the rapid discharge of the battery of a Samsung phone. New phone drains fast

Any owner of a smartphone one day may encounter a problem when his device starts to discharge quickly. What to do, how to solve the problem, and what could it be connected with? These are the questions this article will try to answer.

The main reasons why the battery on the phone runs out quickly

The battery can run out quickly for a variety of reasons. Conventionally, they can be divided into software and hardware.

Too high backlight brightness

Relevant for any smartphone or tablet, even if it is equipped with an AMOLED display. You could increase it quite by accident. Also, some applications are capable of this, including all kinds of launchers.

It has long been possible to reduce the brightness of the backlight directly in the notification panel. Many smartphones support adaptive (automatic) brightness control - it is enabled in the "Settings", in the "Screen" section. Please note that enabling this feature does not remove the user's right to manually adjust the brightness of the display backlight.

Unoptimized applications quickly drain even a new phone

Many users are wondering why the phone began to discharge quickly after they installed some not-so-famous programs. The fact is that not all developers competently optimize their creations. As a result, their applications not only freeze regularly, but also overload the processor too much. This can even happen in the background, which is easy to notice by the heating of the smartphone in the chipset area. Of course, as a result, the phone will be discharged very quickly.

Some programs are designed in such a way that they are constantly doing something in the background. For example, a client social network Facebook collects a lot of information about the user, down to their current location. That is why experienced smartphone owners disable this application if it cannot be uninstalled.

Do not understand which of the programs can negatively affect the battery charge? Then go to "Settings". Find the "Battery" section here. It shows exactly what resources energy is spent on. Including the names of applications that have consumed more than 1% of the charge are displayed here. If something does not suit you, then click on the objectionable program. In the window that opens, you can delete the application, or at least disable it.

Viruses

The charge can also be intensively consumed by sending various information about your actions to the creators' server. At the same time, such applications are well hidden, masquerading as, for example, Google Services. Remove all programs whose names do not tell you anything. You cannot delete real Google Services from your smartphone. If there is a corresponding button, then be sure to use it. And do not download programs from third-party resources, it is better to limit yourself Google Play and the online store of the device manufacturer.

If you still download applications using a pirated method, then install an antivirus on your device. It can be free Dr.Web or paid "Kaspersky". If you have already thought about why the phone is quickly discharged, then run an antivirus scan - it is possible that it will find the culprit of the problem.

Unstable firmware version

Large companies try to check the full program. But even they have misfires. And what can we say about small manufacturers, whose staff consists of a dozen programmers ... In a word, it is not always an update operating system leads to improved performance and expanded functionality. Sometimes, after receiving an update, the user realizes that from now on his smartphone is quickly discharged. This may be due to poor optimization, new pre-installed programs, and even embedded viruses. Suffice it to recall DOOGEE BL7000, in the basic firmware of which there are three viruses that actively devour energy. It was possible to get rid of only one by regular means by disabling the Voice Recorder application. In fairness, software updates in the case of this device have increased the battery life, somewhat drowning out the effects of viruses.

Unfortunately, going back is often impossible. For this reason, we recommend that you do not update immediately after a new version firmware is available for download. Wait at least one week. Read reviews. If everything is in order, then most likely no one will write reviews. And in case of problems, complaints will not keep you waiting.

What to do if your phone gets hot and drains quickly due to a battery issue

Let's move on to hardware failures. The easiest way to blame the rapid consumption of energy is the battery. And he really can be the cause of the problem. Especially if several years have passed since the purchase of the smartphone. The fact is that any battery ages over time, losing its working capacity. Some batteries age faster, some slower.

Nothing can be done about the loss of capacity, it is impossible to restore it. However, no one forbids changing the battery by installing a completely new one. Unfortunately, modern smartphones are increasingly getting a non-removable back cover. In this regard, you will not be able to get the battery yourself, unless you have special tools. However, this can be done at the service center. Yes, you will have to pay for the work and the battery itself. But you will return to the original battery life!

Do not install a high-capacity battery inside your smartphone. Buying it could be a waste of money. The fact is that the power controller is sharpened for the capacity programmed by the creators of the device, it will resist receiving more energy. Of course, these words apply to most, but not all smartphones. But why risk your money?

Power controller issues - phone charges quickly and discharges quickly

Rare case, but it can happen. If you regularly change network adapters, then you could very well come across a low-quality copy. He could give out too high current or high voltage. In this regard, the power controller either fails or starts sending incorrect readings to the system. In the latter case, it may not use the full capacity of the battery. Because of this, the user will immediately notice that now 100% of the charge is draining somehow too quickly.

In many cases, the power controller has to be repaired or replaced, which is what many service centers do. You can try to calibrate the battery with a special application (you can easily find a lot of options). However, this action rarely helps.

Our tips for extending your phone's battery life

A variety of factors could affect energy consumption. For example, a telecom operator may have rebuilt their infrastructure near your place of work. The cell tower is now farther away, and therefore more energy is spent searching for a signal. And there's really nothing to be done about it. But you can use only one data transfer standard for a long trip. The fact is that most of the energy is spent when switching from 3G to LTE and vice versa. If you are driving in a car, then this process will be repeated regularly. But it can be disabled in the operating system settings, for a while, activating only 3G-connection. This is done as follows:

1. Go to "Settings";
2. Go to the "Connections" section (on some devices this step is skipped);
3. Go to the "Mobile networks" subsection;
4. Click on the "Network Mode" button;
5. Select "3G / 2G (auto)", or generally "3G only" or "2G only".

Do not forget that this should only be done on long trips (at least from one end of the city to the other). This advice will also be useful for those who do not need a high data transfer rate on the street.

Disable those wireless modules that you are not using. If it practically does not consume energy, then this cannot be said about Bluetooth. "Blue tooth" can be turned off if you use wireless headphones extremely rare, and you don’t have a smartwatch or fitness watch at all. Many people prefer to deactivate the GPS chip as well, because it also consumes decent amounts of electricity. Although it is easier to prevent them from using objectionable applications, leaving this privilege only to map services and, perhaps, to the browser.

Give up live wallpaper. They are often the ones that consume the most energy. Also, they are not always useful. It is possible that you have downloaded a launcher that is not optimized or filled with ads, and it is because of this that the phone is now quickly discharged.

If nothing helps at all, then you will have to buy a new smartphone. Or get it. This accessory can be kept in a bag, on the desktop, at home in a chest of drawers, and anywhere. The convenience of an external battery is that you can charge your smartphone at any time. In 2016, the wild popularization of such accessories was arranged by the Pokemon Go game, which works in augmented reality and devours the charge in just a couple of hours.

Summarizing

It is often extremely difficult to find out why exactly the smartphone began to discharge quickly. But we hope that our article prompted you to take the right action. Remember that a high battery capacity does not mean that the device will work for a long time. The duration of operation from a full charge, in addition to battery capacity, depends on the following factors:

• The process technology by which the processor was created - the thinner it is, the lower the power consumption;
• Operating system optimization;
• Display manufacturing technology - AMOLED certainly outperforms IPS;
• Smartphone design - the more difficult it is for antennas to catch a connection, the more energy will be spent on it.

In short, do not be surprised that the device will require regular connection of the charger, although inside it is a battery as thick as the palm of an adult.

On android phones, battery problems are quite common. Indeed, sometimes it is very difficult to establish the real reason why the smartphone is discharged so quickly. Generally now this problem not as relevant as before. In particular, the reason for this is that manufacturers install powerful batteries in their flagship devices. However, not only they can provoke a rapid discharge. So, what are the main reasons why the battery runs out quickly on android?

• Bad optimization.
• Powerful specifications.
• Incorrect use.
• Technical difficulites.
• Incorrect firmware.

These are the main reasons why the battery runs out quickly on android. Let's look at each of these reasons in more detail.

Bad optimization

This item concerns phone manufacturers who did not want to work hard enough on the operating time of their devices. This is a purely software problem, which is also related to the firmware. But there are some nuances here:

• Manufacturers often put the same software on different models.
• At the software level, charge control is very poorly implemented.
• No adaptation to large quantity milliamp.

These are the main elements of poor optimization that negatively affect battery life. Manufacturers need to think carefully about why the battery runs out quickly on an android, and take appropriate measures.

Powerful Specifications

If you now have a powerful phone that has a quad-core processor, three gigabytes random access memory, high-quality display and powerful speaker, it is not surprising that they consume more energy. If bad optimization is added, then the battery can be discharged right before our eyes. What do you need to pay attention to on the technical side when it comes to why the battery runs out quickly on android?

• CPU. The clock frequency and the number of cores play a role here. On android phones, coprocessors are not installed, which are characterized by increased energy saving. It also negatively affects battery life.
• Display. This is another reason why the battery runs out very quickly on android. This is especially true for bright displays with high resolution and diagonal.
• Number of SIM cards. Many modern phones on this operating system have two sim cards. If they work in parallel, then this also negatively affects the battery life. This is a very important point, which explains why the battery runs out quickly on an android phone.

Here's what, on the technical side, can drain the battery. Naturally, this is not all. But these points are the main ones. Be prepared to drain your phone quickly if you buy a flagship model.

Misuse

This is also a pretty good reason. And for android phones, it is very relevant. The fact is that the system itself is built in such a way that applications are constantly working inside it. Even the ones that were closed. Such a system consumes a lot of battery. That's why the battery runs out quickly on android. Samsung is one of those companies that has been particularly criticized for this. Actually, not just like that. But if you use your phone correctly, then the likelihood of planting it by the end of the day will drop significantly. And what should be done?

• Turn off wireless and navigation features.
• Lower the brightness to the minimum, or at least turn on the auto mode.
• Permanently close programs that are open in the background.
• Turn off mobile internet.
• Turn off automatic updates.

If you follow these tips, then you will not have the question "Why does the android battery run out quickly on the tablet." This also applies to the phone, like any other device running under this operating system.

Technical difficulites

Naturally, the reason for the rapid discharge of the phone can also be its breakdown. Under no circumstances should it be excluded. What can happen to the device that causes problems when using it?

• The battery capacity has decreased.
• There are problems with the charge controller.
• There are problems when charging the phone.

These are the main reasons why the phone sits down. They concern those people who have already used their device for some time. After all, these problems happen most often over time. However, no one canceled the marriage.

Incorrect firmware

This is another fairly common reason for problems with their phones among android users. If something happened wrong with the firmware, then the phone can also sit down. This is especially true for installation enthusiasts (collected by users). You have to be very careful with them. Not only can they drain the battery, but the warranty also flies.

conclusions

What conclusions can be drawn from this article? You need to carefully look at the following characteristics of the phone:

• Performance (processor, RAM).
• Battery capacity.
• Screen.

They depend on battery life. As for the software part, you should pay attention to:

• Android version. The higher it is, the longer the phone will work.
• The presence of interface add-ons from the manufacturer. "Naked" android always consumes less batteries than interfaces from manufacturers.

If you pay attention to these points when buying an Android smartphone, then its battery life will be much longer. You will be able to stay in touch with your loved ones for a longer period of time.

Most gadget owners faced one problem: at the wrong time, the device turned off due to a “tired” battery. Why is my smartphone battery draining fast? The breakdown of the phone, which the first thought arises, is not the only reason for the occurrence of an unpleasant situation.

In order not to suddenly be left alone with discharged equipment when this is unacceptable, it is worth considering the factors that affect battery performance. They are divided into groups: related to the basic technical specifications, activity of programs that have arisen due to operational errors. Knowing the reasons for the discharge will help you understand the principles of increasing the battery life for your smartphone.

Why is my battery draining unusually fast? Perhaps it's the wrong choice of power source. When buying phones, battery characteristics play an important role.

Among them:

• Capacity(unit - mAh).
• (Ni-Cd, Li-Ion, Li-Pol).
• Operation period .

A battery with a rate of less than 1600 mAh is unlikely to be able to last all day without recharging against the background of active Internet surfing, calls and playing games. A relatively comfortable time of using a smartphone starts at 2000 mAh. The "resistant" phones have batteries with a capacity of 3000 to 4000 mAh.

The type of battery also affects the duration of its use without charging. Nickel-cadmium representatives (Ni-Cd) have gone down in history due to fragility, low energy consumption, unjustified production costs. Metal hydride (Ni-MH) batteries, which were built into old, large, low-cost phones, have a relatively long battery life, but are inferior to other types.

Modern smartphone batteries are based on lithium (Li-Ion, Li-Pol). Both representatives are similar in their characteristics: high mAh numbers, stable operation, no “memory effect” (gradual loss of nominal capacity). However, they are sensitive to temperature. environment, long stay in the state of discharging / charging.

The previous period of use refers to used batteries. For example, on a modern Samsung smartphone, the battery normally lasts from 1 to 3 years (depending on the intensity of use, device model). The need for more frequent recharging of a new phone is noticed after a year of use. You should not expect long work if the battery of the smartphone served the previous owner for 4 years.

Lithium-ion batteries of smartphones are subject to the memory effect, as a result of which they begin to lose capacity over time. It will help in such a situation.

Basic and installed software

The indicated reason for the rapid discharge of the battery is more relevant to the owners of smartphones on Android. Many gadget owners notice: the more programs installed in the device, the faster it “gets tired”. The battery on the phone is quickly discharged due to the frequent automatic launch of applications, their incorrect installation. Incorrect autorun software does not allow the processor to go into "sleep" mode. In addition, the battery can quickly run out due to the accumulated software errors that have arisen on Android.

Sometimes cleaning of unnecessary software does not help solve the problem. Android initially includes services that act by default, but are not always needed by the device owner. Not all users are aware of their presence on their smartphone, although pre-installed programs can make the device discharge much faster. This is especially true for Samsung phones: often high-tech "stuffing" does not match the declared battery capacity.

Malware

Technological progress has played a dual role: the growth of Android functionality has led to an increase in the number of system vulnerabilities. Often, an attempt to download an antivirus from unverified sources, on the contrary, ends with the installation of malware.

"Symptoms" of infection of a smartphone on the Android platform:

• program startup slowdown ;
• frequent freezes ;
• rapid heating of the battery ;
• the appearance of banners, other forms of advertising in atypical places .

Features of use

The battery of the smartphone is discharged faster when surfing the Internet, watching movies, running games with high quality charts. Making regular calls, sending SMS, listening to music require less battery consumption. The quality of the incoming signal plays a role: the worse it is, the faster the smartphone is discharged due to the operation of sensors that “catch” the disappearing network.

Why is the battery draining quickly on a smartphone? Even the climatic parameters of the environment affect the duration of the battery operation. Energy at -20°C is spent several times faster than at plus. When making a call in the cold, you need to be prepared for a sharp shutdown of the smartphone.

What can be done?

There are several ways to slow down battery consumption. Radical - purchase a new original battery. However, it is worth delaying this and trying to extend the life of the smartphone in other ways.

Changing default settings

What to do? To begin with, it is worth trying to solve the problem of a quickly dead battery by optimizing settings.

Measures:

• Changing screen settings . The battery drains more slowly at low brightness. The role is played by minimizing the auto-shutdown time of the screen.
• Stop communication modules . Turning on Bluetooth accidentally can drain your phone faster than usual. It is not recommended to run WI-FI where it is not needed or absent. This module often becomes the "culprit" of automatically downloading unnecessary updates. When not in use, it is recommended to turn off mobile data transmission. The "Airplane" mode helps to temporarily stop all the considered modules at once. However, this will lead to the inability to use SMS, phone calls.
• Sensor setup . A lot of batteries "eat up" the auto-rotate function and GPS. If they are not needed, it is recommended to temporarily disable them. The reason for the acceleration of discharge is also the auto-adjustment of the brightness of the screen (due to permanent job special sensor). Some software, for example, a pedometer, runs an accelerometer, a gyroscope in the background, which reduce the battery level.

Working with software

You should remove applications that speed up the discharge of your smartphone. If it is not initially clear whether the installed applications “overload” the system, you can diagnose it before uninstalling. To do this, you need to translate Android or another system into safe mode(only standard services are launched on the smartphone). If the phone starts to discharge more slowly, it is recommended to uninstall third-party applications.

Disabling unused pre-installed services will help get rid of fast discharge. It is worth noting that some of them cannot be deleted, but suspension of application activity is acceptable. It will not be superfluous to install a reliable antivirus.

Data reset

It is an extreme measure that allows you to fix the accumulated system errors in your phone, get rid of malicious applications. The settings return to default. All data saved by a non-manufacturer is erased.

How not to do

Sometimes the wrong measures can shorten the life of the battery, in some situations even the smartphones themselves suffer. For example, some sources recommend calibrating by cycles of fully discharging, temporarily removing the power supply, then fully charging it for at least 8 hours. The method was suitable for older types of batteries, as the battery sat down due to the "memory effect". Lithium batteries after such calibration will become unusable faster than originally stated by the manufacturer.

In addition, you cannot:

• disassemble the battery ;
• deform;
• try to influence her with cold, heat (Such extreme methods are also circulating on the net).

In most cases, the observance of the considered recommendations helps to "reanimate" a rapidly discharging smartphone. If there is no result, it is advisable to contact the service center. Buying a smartphone with characteristics that initially meet the individual requirements of the owner, following the official user manual and replacing the battery when it becomes unusable with the original one (from the manufacturer) helps to avoid the troubles associated with the rapid discharge of the phone.

Users of different smartphone models are faced with the fact that the device begins to lose charge catastrophically. If the device previously held 1-2 days, and suddenly does not survive until the evening - it's time to sound the alarm. It is important to understand why the smartphone is quickly discharged, to understand the reasons that the battery runs out. You can take action and the situation will improve.

Why is my phone battery draining fast?

There are a number of reasons for such a problem. Sometimes the battery on the android runs out due to a technical malfunction or breakdown. The user can provoke the occurrence of such a difficulty through ignorance. There are applications on android that waste a lot of energy and “sit down” gadgets. Frequent use of built-in smartphone functions, automatic location detection can also speed up discharge.

Charges quickly and discharges quickly

The primary source is a battery failure. It loses its resource over time and the battery on the android runs out. If it is removable, replace it. If built-in - contact the master. Less commonly, the cause is a breakdown in the electronics of the gadget. In the same service center, specialists will diagnose and identify the problem. After that, the problem with the charge circuit will be fixed. Less commonly, the cause lies in a battery calibration failure.

Takes a long time to charge and discharges quickly

Make sure the battery is not damaged. If there is no problem with it, then the reason is the applications. The software requires a lot of energy - just get rid of it and the problem will be solved. Low-quality battery saving software can even worsen the performance of the gadget. If the above reasons are excluded, contact the masters. It is possible that the battery on the smartphone is running low due to a failure in the electronics.

Discharges quickly in standby mode

It happens that Android devices sit down regardless of the activity of use, if the music and the browser are turned off. The reasons may lie in applications that run in the background and drain the battery. Extra energy costs are due to the inclusion of the Internet, navigation and similar functions. When the screen is on, pay attention to the brightness: if it is above 75%, then the battery on the phone quickly runs out. Live wallpapers also hurt battery life.

New phone drains fast

It's annoying when a brand new android smartphone pleases you for 8-10 hours, and then asks you to connect to a charger. The reason may lie in a manufacturing defect. On some models of smartphones, the battery capacity is initially small. Why smartphones are quickly discharged - because it comes across not an original product. Fake gadgets are characterized by poor workmanship, low battery capacity. Another option is incorrect operating system settings. Try turning on the battery saver function, or make a correction yourself.

The phone heats up and drains quickly

A noticeable heating of the device indicates the active operation of the processor. Overloading entails a reduction in the life of the device. You need to find the cause of the load on the processor and understand why the gadget sits down. Try to restart the device, clear the cache yourself or with the help of programs. If this does not help, remove the new software. If all else fails, do backup data and a complete reset (Hard Reset).

What to do if the phone is quickly discharged

With the help of simple actions, you can reduce the load on the processor, prevent battery drain in standby mode. Try to perform a series of operations, to understand why the smartphone is quickly discharged. Do this to avoid charging your smartphone every 8 hours:

• Screen brightness consumes a lot of power. Set the automatic mode, adjust the optimal comfortable brightness within 50-75%.
• Turn off the automatic screen rotation feature.
• Set sleep mode to turn on at the most convenient moment. The smartphone will automatically close background applications, they will not consume energy.
• Turn off mobile data and Wi-Fi, location (gps) and the problem of many Bluetooth smartphones when not in use. The included functions and in anticipation significantly discharge the device.
• Manually disable apps that you are not currently using.
• Disable account sync.
• Clear the application cache manually in the settings or using special software.

What is the best battery saver app

Android apps consume a lot of power and cause your phone to sit down. The creators of phones fail to influence this globally. The developers offer a number of high-quality software to save battery. Choose convenient and enjoy:

• greenify. The software is free and works offline. Designed to reduce energy consumption in rest mode, turn off particularly "gluttonous" programs, games. Greenify is able to disable even those processes that are not displayed during manual cleaning.
• DU Battery Saver. The program is particularly popular among users - more than 100 million downloads. The software is able to disable background processes, compile battery usage statistics. The optimization function detects and disables energy-consuming processes.
• Easy Battery Saver. The application is convenient and interesting. In it you will find a number of rules on what to do if the battery on your smartphone runs out. It will not interfere with the operation of the smartphone, troubleshoots in sleep mode. Using the software will not impair the performance of the phone.

Video

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.
• Turned on too high level screen brightness.
• Resource-intensive features included: GPS, NFC, Bluetooth, etc.
• Long distance to the base station of the 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 information 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 with a higher voltage and current than the manufacturer provided (the required level of current and voltage is indicated on the charger that was sold 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 be charged 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 a lot of 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 obtaining root (superuser) rights 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 of unnecessary files, cooling the processor, optimizing charging, 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 for the battery draining 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. Often they carry out activities that are invisible to the user, and the only signs of their presence are empty accounts and very fast battery discharge, including in standby mode.

Hidden virus infection should be excluded 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.
• Wi-Fi, geolocation, mobile Internet and other modules are enabled on the device without your participation. Or they can't be turned off.
• Unknown numbers appeared in the list of outgoing calls and SMS, and views of sites that you did not visit appeared in the browser history.
• 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.

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 of the devices remain active - the cooler continues to rotate, indicators are lit, etc. The exact 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, it 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 appeared (if you managed 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.
