The graphical interface of the system eats up the battery. So, here is a list of seven main ways to save battery power on Android smartphones.

One of the most pressing problems of Android smartphone owners is that they are very The battery runs out quickly. How to reduce energy consumption if your Android is eating up battery in unlimited quantities and it shrinks in a few hours, even without very active use? We present to your attention a list of the most common reasons for the rapid discharge of a smartphone battery and ways to extend its life until the next recharge:

• Do not turn on Wi-Fi, Bluetooth, 3G, NFC unnecessarily- use various communication functions only when you need them and do not forget to turn them off as soon as they are no longer needed, this way you will significantly increase the time until the next recharge of your smartphone.
• Do not install live wallpapers and many widgets on your smartphone, but it’s better to turn them off altogether. Animation on the screen and constantly updated widgets are very power hungry.
• Disable location tracking wireless networks (Settings -> Locations).
• Don't use task killers(Task Killers), applications for closing background applications - many owners of Android smartphones mistakenly believe that forcibly closing applications running in background, will allow the smartphone to last longer until the next recharge. In fact, task killers are not only not needed, but it is also better to use them only in individual cases. Firstly, all Android smartphones have a function to close applications that have completed their tasks or those that for a long time didn't apply. Secondly, there are applications that consume virtually no energy and must run constantly (for example, an alarm clock). During forced shutdown Applications have to restart, which only drains the battery more than running them in the background.
• Turn off vibration, vibration feedback and backlight touch buttons (if you have them) - in theory, the vibration signal was made in order not to disturb the quiet environment with a loud phone signal. Using sound and vibration at the same time will drain your battery faster, so it's best to use them separately as appropriate. Features such as vibration feedback when pressed and button illumination can also be turned off in order to add a few points in favor of energy saving.
• Remove all old programs and irrelevant applications- quantity free space does not affect battery life, but such apps may also drain your battery by downloading updates in the background.
• Increase the time between app and widget synchronizations- the less frequently synchronization occurs, the longer the smartphone battery will last;
• Get rid of automatic update applications- Almost all applications check for updates in the background from time to time. Constant connection to the Internet accelerates energy consumption and shortens battery life.
• IN Google settings Maps disable "Sending geodata" and "Location history".
• Turn off Google Now, if you don’t use it, it is also quite gluttonous.
• Don't forget to adjust the screen brightness- indoors it can be reduced so as not to waste battery energy.
• Reduce the amount of time before the screen turns off- this is not much, but it will still extend the battery life.
• Turn off your smartphone at night- It is not advisable to charge your smartphone all night, but turning it off or at least switching to airplane mode will significantly save your battery level at night. Thus, by charging your smartphone before bed, you will have a 95-100% charged device in the morning.
• Disable unnecessary sensors- for the operation of various smartphone functions, for example, the screen rotation function, sensors are used that also need energy, so turning off sensors that you do not need will further reduce the energy consumption of your smartphone.
• Use subtle themes and desktop themes- the smartphone screen is the biggest drain on the battery; the more black there is on the screen of your smartphone, the less energy it will need to backlight the screen.

With the problem of discharging too quickly battery(battery) almost all users of mobile gadgets encounter. The problem occurs gradually and goes unnoticed for some time, but one day the owner notices that time battery life 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 won’t turn on at all.

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

Reasons for rapid battery discharge

• The actual battery capacity of a smartphone or tablet is lower than indicated in the specifications.
• Battery capacity has decreased due to normal wear and tear.
• Ambient temperature is below +5 ⁰C or above +30 ⁰C.
• The screen brightness level is too high.
• Resource-intensive features included: GPS, NFC, Bluetooth, etc.
• Long distance to base station mobile operator.
• Apps and widgets running in the background consume energy.
• Frequent turning on and off of the device.
• Infection with mobile viruses.
• Malfunction 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 decide to double-check it. Most believe documents, as well as program indicators, which also do not always display reliable data.

The reason for the discrepancy between actual information and nominal information does not always lie in deception on the part of the manufacturer or seller (although this also occurs); lithium power supplies simply lose their capacity during long-term storage. If you bought a device that was released a year ago, even if stored correctly, its battery became less capacious by 2-6%, and if stored incorrectly (i.e., when charged to 100%) - by as much as 15-30%.

To calculate the actual battery capacity, charge-discharge devices, like iMAX, or home-made spark gaps, complete with a multimeter or USB tester, are used. The exact indicators are determined during the discharge of a fully charged battery.

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

Capacity has decreased over time

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

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

Frequent short-term recharging, contrary to popular belief, does not harm the battery. The current with which it is charged has a much greater influence. It is preferable to charge lithium batteries 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 cold or hot weather

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

If you don't do this too often, the battery won't wear out quickly, but for calls in the cold it's still better to use a headset and keep the phone in a warm pocket.

High screen brightness level

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

The use of adaptive backlight, which changes depending on the ambient light (available only on devices equipped with a light sensor), helps reduce battery consumption. To enable it, select the “Auto” checkbox in the screen brightness settings. To prevent the screen from remaining on when you are not using the gadget, set it to go into sleep mode after 30-60 seconds of inactivity.

Resource-intensive features

After the screen, the next active consumers of energy are:

• geolocation;
• live (animated) wallpaper;
• NFC and Bluetooth;
• mobile Internet (3G, 4G).
• Wi-Fi.

If they are all on at the same time, even the most capacious battery will drain very quickly, so whenever possible, turn off what you are not using.

Unstable cellular connection

You may have noticed that when you spend a long time in places where the phone has poor reception of the operator's base station signal, for example, outside the city, the battery discharges faster than usual. This happens because more energy is spent maintaining an unstable, intermittent connection.

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

Apps and widgets running in the background

Many Android applications and widgets, after installation, register themselves in 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 startup should be kept under control and allowed only to those programs that need it (antivirus, optimization tool, utility utilities, instant messengers, etc.).

Unfortunately, the autorun control functions of custom and system applications not in Android. But it becomes available after receiving root rights(superuser) and installing special utilities on the device, such as:

• Startup Manager and some others

There are utilities that allow you to manage startup without root rights, but they do not work on every gadget and do not always work 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, which in turn heats up the battery. And when heated, as we know, the phone battery drains very quickly.

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

• • DU Battery Saver etc.

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

Frequent reboots and turning the device on and off

Wanting to save charge, some users regularly turn off their mobile gadget. Sometimes even several times during the day. This is another reason why the battery drains too quickly, since when the device starts up and the operating system loads, the energy consumption is close to the maximum.

While you are not using your 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 an energy saving mode, the activation button for 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 empty accounts and very rapid battery drain, including in standby mode.

Hidden virus infection should be excluded in case of any non-standard behavior of the gadget, for example:

• The phone or tablet wakes up from standby mode without any active action on your part.
• The device is in sleep mode and becomes warm.
• Wi-Fi, geolocation, mobile Internet and other modules are enabled on the device without your participation. Or they cannot be turned off.
• Unknown numbers appeared in the list of outgoing calls and SMS, and views of sites that you have not visited appeared in your browser history.
• An application has assigned itself as a device administrator without your knowledge.
• For unknown reasons they stopped launching Google Play antivirus and other security applications.
• Any system functions have stopped working.
• Volume increased for no reason network traffic devices.

System or hardware failure

Some users of PCs and laptops 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 light up, etc. The exact same problem occurs on mobile devices, it’s just not so easy to notice, because smartphones and tablets do not have a cooler, and the indicator only shows the charging stage. In the event of such malfunctions, the device essentially remains on constantly and, accordingly, even in a “sort of turned off” state actively consumes battery energy.

The causes of such problems may be faulty applications, viruses, operating system errors and malfunctions in the device’s hardware (including connected devices - memory cards, SIM cards, etc.).

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

In such cases, what can the user do without contacting the specialists:

• Remove applications installed before the problem appeared (if you were able to record the time it started).
• Conduct an anti-virus 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.
• Reflash the device with known working firmware.

After each manipulation, check the gadget by turning it off. If the problem is not solved, you will have to take it to a service center for repairs, since the problem itself will not go away, and the battery will exhaust its life much faster than during normal operation.

Google annually adds many settings and functions to the Android operating system, many of which are hidden from the eyes of ordinary users. This was done on purpose, but with good intentions. The American corporation believes that if an inexperienced owner of some inexpensive Android smartphone accidentally activates certain important settings, then his device may start to work slower or discharge much faster, so right out of the box all smartphones based on Google’s OS have only basic functionality activated, but this is very easy to fix.

Although every year all smartphones work longer on a single battery charge, largely due to better software optimization for hardware, but hidden setting in all Android smartphones, it significantly increases battery life, and now absolutely anyone can activate it, since it is definitely available in any custom firmware and in all models of mobile devices.

All smartphones based on operating system Android systems have an incredibly large power reserve, which is simply excessive for solving simple everyday screens. It's like driving a car, sometimes pressing the gas to the floor, and then slowing down again. In the case of smartphones, it’s not the gasoline that drains faster, but the battery charge. To increase battery life mobile device you need to launch “Settings”, and then go to the “Battery” section.

In the “Battery” section, three vertically located dots should be visible in the upper right corner, which you need to click on. In the menu that appears, you will need to select “Power Saving Mode” and then activate it. As a result, processor performance will be reduced, which will allow up to 50% increase in battery life on a single battery charge. This feature is available in all smartphones and tablets running Android 5.0 Lollipop and higher.

To achieve an even greater effect, the editors of the site recommend installing the “Doze-energy-saving” application, which significantly increases the battery life of all Android smartphones, since a lot of charging is “eaten up” by processes running in the background, which the user does not even see. After installing it, you need to select from the list only those programs and services that should continue to function normally.

It is worth choosing the most basic messengers, email clients and other core programs that need to receive notifications in real time rather than delayed. This program works in such a way that all processes that are running in the background and consuming battery power are automatically frozen. This does not cause any harm to them or the data stored in them, and using this application can significantly increase battery life by up to 40% of the standard. This is especially noticeable at night, when without this program the smartphone’s battery will be discharged by 10-12%, and with it only by 5-6%.

Don't miss your chance! Until April 21 inclusive, everyone has a unique opportunity to use Xiaomi Mi Band 3, spending only 2 minutes of their personal time on it.

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

Why does my phone battery drain quickly?

There are a number of reasons for this problem to arise. Sometimes the battery on your android runs out due to a technical malfunction or breakdown. The user may cause such a difficulty to arise out of ignorance. There are applications on Android that waste a lot of energy and drain gadgets. Frequent use of built-in smartphone functions, automatic detection places can also speed up discharge.

Charges quickly and discharges quickly

The primary source is a battery failure. Over time, it loses its resource and the battery on the android runs out. If it is removable, replace it. If it’s built-in, contact a specialist. Less commonly, the cause is a breakdown in the electronics of the gadget. In the same service center specialists will carry out diagnostics and identify the problem. This will fix the problem with the charging circuit. Less commonly, the reason 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. 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 specialists. It is possible that the battery on your smartphone is dying due to an electronics failure.

Discharges quickly in standby mode

It happens that Android devices die, regardless of the activity of use, if the music and browser are turned off. The reasons may lie in applications that run in the background and drain the battery. Extra energy consumption is caused by turning on 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 drains. Live wallpapers also take a toll on your battery life.

New phone runs out of battery quickly

It’s annoying when a brand new Android smartphone pleases you for 8-10 hours and then asks to connect to charger. The reason may lie in a manufacturing defect. Some smartphone models initially have a small battery capacity. Why do smartphones run out of charge quickly? Because they come across a non-original product. Fake gadgets are characterized by low quality workmanship and small battery capacity. Another option is incorrect operating system settings. Try turning on the battery saving function or make the correction yourself.

The phone gets hot and discharges quickly

If the device becomes noticeably warm, this indicates active work processor. Overload leads to 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 freezes. Try restarting the device, clearing the cache yourself or using programs. If this does not help, remove the new software. If all else fails, do it backup data and full reset settings ( Hard Reset).

What to do if your phone runs out quickly

By using simple actions You can reduce processor load and prevent battery drain in standby mode. Try to perform a number of operations to understand why your smartphone discharges quickly. Do this to avoid charging your smartphone every 8 hours:

• Screen brightness consumes a lot of power. Set to automatic mode, adjust the optimal comfortable brightness within 50-75%.
• You should disable the automatic screen rotation feature.
• Set sleep mode so that it turns on at the most convenient moment. The smartphone will close background applications on its own; they will not consume energy.
• Disable mobile internet and Wi-Fi, location (gps) and the problem of many Bluetooth smartphones when you are not using them. Functions turned on and waiting significantly drain the device.
• Manually disable apps you don't use at the moment.
• Disable synchronization with your account.
• Clear the application cache manually in the settings or using special software.
