Why does my smartphone battery drain suddenly? Close background applications. Reasons for rapid battery drain and ways to solve them

All modern portable electronics are powered by batteries, which need to be constantly recharged. As a rule, every modern smartphone has to be connected to a charger once a day, but sometimes this has to be done even more often. Immediately after purchasing a new phone, it can work for quite a long time, but gradually its autonomy will decrease. This is due not only to the chemical process of battery wear, but also to not entirely reasonable use software installed on the phone.

The editors of the site have compiled the top 7 main reasons why any smartphone quickly runs out of power. As a rule, such mistakes are made by novice users, however advanced user from this small material you can learn something useful for yourself that will really increase your time battery life any smartphone by at least 10-40%.

Reason 1. The higher the screen brightness, the faster the battery will be consumed. That is why at night and in the evening, when the brightness is at a minimum, the phone will work longer. To optimally use battery power, you should turn on auto brightness, or adjust it yourself each time to suit your needs.

Reason 2. Many smartphone owners like to install live wallpapers. Few people know about this, but their use creates a certain load on the process and the graphics accelerator, as a result of which the phone will not only work slower, but also discharge faster.

Reason 3. All modern smartphones support the “Auto-rotate screen” function, which works due to the built-in mobile devices accelerometer. He constantly works, monitoring his position in space. In order not to waste charge on it, you should select only one screen position - vertical, and then turn it off if necessary.

Reason 4. The biggest battery drain, right after screen brightness, is network drain. mobile operator. A phone that is constantly connected to something via 3G/4G or Bluetooth will discharge noticeably faster than one that does not catch the operator’s network, but is still connected to Wi-Fi. To reduce battery consumption at night, you can turn on airplane mode, thereby reducing battery consumption to a minimum.

Reason 5. Background processes can drain your battery a lot various applications, especially if they are written “crookedly”. To avoid unnecessary battery consumption, you should use the power saving settings in operating system, or use special programs, like Battery Doctor, which allow you to forcibly prohibit certain programs from working in background.

Reason 6. It is advisable to avoid using a smartphone when it is cold outside. The fact is that all modern batteries react negatively to negative temperatures - they discharge faster and can turn off unexpectedly. If you suddenly need to call someone right on the street, then you should, if possible, go to a store or somewhere else in order to make a call in a warm environment.

All these reasons allow you to reduce battery consumption, but do not forget that over time, the battery of any phone will lose its capacity, as a result of which the phone will begin to work noticeably less. It is extremely easy to fix this - after 1-1.5 years of active use of the new smartphone, you should think about replacing the battery with a new one. This will again force electronic device work as long as immediately after its purchase.

Battery discharge during its operation is a common occurrence, but what to do when the phone begins to discharge for no apparent reason.

For example, you charged it and put it on the bedside table overnight, but by the morning there was almost no charge left. Let's figure out why a smartphone discharges for no reason and what to do about it?

In geek parlance, this behavior of a smartphone is called “battery wasting.” Often it happens because the smartphone cannot switch to energy saving mode in those moments until the user touches it. This phenomenon has its own reasons. These could be:

— Crooked software (third-party or system).
— Crooked core of the system.
— Weak signal GPS modules WI-FI BT NFS or mobile network.
— Synchronization and Push notifications.
— Poor quality firmware.
— Degradation of the battery (battery).
— Charge controller glitch.

All of these reasons (except the last two) can be corrected programmatically. The first thing to be guilty of is third-party software.

Go to settings and look at statistics on charge consumption. If you are lucky, you will find the cause of the “eating.” This program will be at the top of the energy-consuming list. It's best to just remove it or use it alternative program. Often the problem cannot be solved so easily and a complete cleaning is necessary.

Review your software on your smartphone. Pay special attention recently installed programs. Remove everything unnecessary and rarely used, or replace it with less energy-consuming applications.

Try removing unnecessary widgets from your desktop, disable live wallpapers (if any).

Turn off search Wi-Fi networks. To do this, go to Settings — WIFI – Additional features . And here you need to uncheck the box - Always look for networks.

Disable background work geolocation transmission services. Settings - Location. And disable sending location data. You can also turn it off not really necessary synchronizations. Usually this can be done in the settings, in the Account item.

Disable all unused wireless communication modules - Bluetooth, NFC. Avoid push notifications on social media as much as possible. networks and other applications. Try not to use Double Tap or swipe to wake up your smartphone. At poor quality It is better not to use LTE for communications.

Google services can also consume quite a bit. They constantly go online for updates and send a ton of data to the Internet. Disable in Google Play automatic update. You should also disable calling the assistant by voice.

If all of the above instructions do not help, reset your smartphone to factory settings.

Go to Settings – Restore and reset – Reset all phone settings. In this case, all photos and videos may be erased. You need to take care of this in advance; transfer important data to external storage or to a computer. Do backup copy phone book.

If you are not afraid of drastic measures, reflash your phone. If it doesn’t help, it’s time to change your battery. To verify that the battery is faulty, there is a very simple test.

You need to charge your smartphone to 100% (battery temperature should be between 22-28 C), and disconnect it from the power supply. Next, wait a couple of minutes and turn it on. If after loading you still have 100%, the battery is in excellent condition, there is nothing to worry about.

The charge dropped by 1% - also normal. If by 2% or more, the battery capacity began to fall, and the more the charge percentage dropped, the more worn out your battery was. It's time to change. Replace it yourself or at a service center.

Another problem is . Unfortunately, this also happens even on top smartphones. The controller fails and incorrectly reads data from the battery. Only specialists will help you here. The phone will have to be taken to a service center, where it (the controller) will be re-soldered. Not difficult, not very expensive, but you may have to wait.

I hope this article was useful to you and you still found out why your smartphone discharges for no reason. See you in a new article.

Many owners of smartphones from Samsung and other popular brands are familiar with one problem - the battery on Android quickly drains. The full energy reserve approaches zero within 13-14 hours of even inactive use. A similar problem occurs among owners of tablets running this operating system.

Why does my phone run out quickly?

Free Android platform has many features and settings that drain the battery quickly. They are enabled by default, and consume power even when the display is turned off (in the background). Most users don't use half of these services, so they should be disabled. Another reason that will crash your mobile phone is viruses. Features this problem:

the phone starts to warm up and slow down;
Advertising appears where it shouldn't be.

Rules for using the Android battery

Previously, when buying a new device, sellers recommended “boosting the battery” - completely discharging it and charging it several times. This advice is already outdated, but modern batteries such as Li-Pol or Li-Ion will be more likely to cause harm than benefit. Saving battery on Android starts with proper use apparatus. Specialized publications cite several important theses:

Completely discharging and charging the battery to zero leads to a reduction in its “lifespan”. The more such cycles are carried out, the faster the part will deteriorate. This happens due to chemical degradation of the battery.
Your Android device should charge when possible.
Try to always use "native" charger. Yes, now almost all devices use the same connector, but there are some peculiarities regarding voltage indicators. Problems especially often occur due to recharging from a computer.
It is not recommended to leave the phone in the hot sun while charging. This is a minor factor, but it can affect the performance of the battery.

What to do if the battery runs out quickly on Android

It is not always possible to replenish the energy on your phone in a timely manner, so if your Android battery is quickly draining, you can use ways to optimize the operation of your mobile phone. You need to disable unnecessary services,sensors to reduce power consumption by the operating system. All the methods described below are suitable for any smartphone model.

This is the most important energy consumer, which will drain your battery at an accelerated pace. Recommendations:

The battery will discharge faster at high brightness. Each phone has a setting for this indicator, so you should set it lower when indoors.
Additional savings will be made by setting a shorter period of time for the screen to turn off automatically.
In devices with AMOLED display You can reduce battery consumption by using dark wallpapers because black colors require virtually no power when displayed.

Communication modules

These services work even when the display is turned off in the background, constantly loading some data and causing the battery to discharge more actively. Almost all settings are in the " wireless technologies" The name may differ depending on different models devices, but the essence is the same. You can optimize this side as follows:

Turn off 4G LTE if you don't have coverage in the city.
Turn off mobile internet if you don't use it.
Often WI-FI is enabled on the phone by default. This is a very serious power consumer and should be disabled when not in use. The module is regularly connected to Google service Play to download updates for apps and then installs them in the background.
Bluetooth. A technology that is rarely used these days, but it consumes the battery.

Modern models telephones are supplied a large number additional sensors, due to which the device may discharge faster than necessary. Disabling them will help save power on your smartphone. You should deactivate:

GPS. In your phone settings, find the section with geographic positioning and turn it off. As a rule, this item is placed on the widget panel or in the main top menu phone. It would be a good idea to disable sending location information in the “Personal Data” section.
Additionally, the auto-rotate screen function quickly drains the battery. On version 5 of Android, the Google Fit application often uses the accelerometer/gyroscope in the background, which reduces your battery charge.

In the same group, the vibration response when pressing the device keys is taken into account separately. To create it, an electric motor (mechanical part) is used, which requires certain energy inputs. To completely reduce battery consumption on Android, in addition to the previous points, simply remove accounts and disable synchronization with cloud services. These background programs They also drain the battery quickly.

Which battery saving program is better?

To carry out all the above actions, third-party developers have created special applications that help optimize a number of settings through user-friendly interface. Quickly turn off all sensors, wireless connections and other options are available using the Battery Doctor utility. This free program with wide functionality will help you optimize settings if your Android battery drains quickly. In addition to the ability to quickly disable all unnecessary services, this application shows the remaining operating time of the device.

Video: how to extend battery life on Android

One of the most common problems modern gadgets- the battery runs out quickly on Android. Many users of smartphones from Samsung and other brands note that the battery discharges very quickly (within only 12-15 hours). For active people who cannot imagine their life without a phone, this is absolutely unacceptable. Turning off your phone at the most inopportune moment can lead to you missing an important call and, accordingly, being left completely without communication. If the Android OS is eating up your battery, you can optimize the operation of the OS, perform calibration or customize the interface.

Reasons for accelerated discharge

Before answering the question why the phone battery drains quickly, it is necessary to identify the cause of this problem. This will help you take the right measures. The first and most commonplace option is battery wear. Despite the fairly high development of technology, the batteries on phones have a relatively short lifespan. You can see the “life” level of your battery using these special applications, like Battery Info or MacroPinch Battery. Also, swelling of this element indicates a clear need for replacement. A damaged battery may cause your phone to not charge.

Often smartphones from Samsung or other manufacturers are equipped with a rather weak battery. The phone discharges quickly, especially when the processor uses all its capabilities. Modern 4- and 8-core processors require a battery of 2500 milliamps. Sometimes the OS and hardware very quickly eat up all the charge.

The reason that the device quickly sits down may be the OS itself. Numerous processes, background programs, widgets and wallpapers, little by little, eat up battery power. Also constant search network may cause the phone to begin to discharge quickly. Here you need to configure the OS, i.e. turn off unused software.

You Samsung owner or any other gadget on Android and your battery runs out quickly? Then we recommend that you familiarize yourself with the list useful tips. These recommendations can completely solve the problem fast discharge, and extend the life of your smartphone on a single charge.

Optimal charging mode

If you have a brand new recently purchased Samsung or any other smartphone with a lithium-ion battery, then you can extend the service life with the right charging technology. You need to put your gadget on “recharge” when the charge bar is around 10-20 percent. Fast charging it is necessary to carry out up to 80-90 percent.

Lithium ion batteries on Android do not have a “memory effect”, and also do not tolerate large depth of discharge. How to save battery power? Just avoid completely discharging your smartphone and recharge it regularly. If the percentage drops below 15 and there is no way to charge your phone, try not to use your smartphone. You can also deactivate the gadget. This is the answer to the question of how to save battery life.

Disable unnecessary things

Batteries are often discharged due to various background processes and numerous active services. Accidentally turning on GPS, flashlight or auto call - all this eats up battery life. To turn off unnecessary processes, you need to take a couple of simple steps:

Be careful as stopping some services may interfere with your phone's functionality. Some of the processes are re-enabled after a reboot.

Lighten up the interface

If your phone or tablet is quickly draining, you may have too much brightness and live wallpaper. Using a smartphone is quite convenient even at an average brightness level, and the animated wallpaper can always be changed to normal beautiful screensaver. Also set the smart sleep mode. This function unloads inactive processes from memory, while minimizing device power consumption. As a result, Android consumes less battery, and the phone lasts longer. You can change the brightness settings in the “Screen” section of the “Brightness” submenu.

Minimizing network consumption

If your Android device is quickly draining, try turning off the SIM card. In areas with weak signal The phone is constantly searching for a connection to the network. Combined with the operation of the OS, this leads to accelerated discharge. How to disable a SIM card? This is done using standard settings phone:

Go to home screen phone.
Swipe down to open the quick access menu.
Activate Airplane Mode.

To prevent the mobile network, GPS and communications from eating up the battery, you can activate this mode.

Battery calibration

What should I do if, when charging, the system does not bring the charging percentage to 100? This is a very common question. The smartphone does not charge to the maximum percentage if the battery is not calibrated. The calibration process is to bring the battery to its optimal state. Calibration will also help solve the case when the phone takes a long time to charge.

You can do calibration using special applications that are distributed free of charge in the Google Play store. For example, Battery program Callibration automatically configures the battery after complete discharge and charging. The user will only need to press one Calibrate button. Some gadgets have a standard analogue of this application in the operating system. If you urgently need to drain your phone, activate Wi-Fi, and then simply launch a “heavy” application that will give you heavy load on the processor and OS. This is the easiest way to quickly discharge a mobile device. If the battery does not charge at all, check the power supply or socket on your phone.

Now you know why the battery drains quickly and how to fix it. If the system is working correctly, nothing volatile is running on the phone, and the battery on Android is quickly discharged, you must always have alternative source nutrition.

The easiest option is to carry an extra battery with a full charge. This will completely solve the problem when Android quickly discharges. Users can make replacements quickly and easily. The best option is to buy Power Bank. This is a portable charger that contains a battery increased capacity(from 10 thousand milliamps). You can charge several devices from it at once on the road or in nature.

Instructions

First you need to go to the “Wireless Networks” settings section. Initially, see if systems such as Wi-Fi, Bluetooth and GPRS are enabled. These networks consume a total of large number battery charge. And if you are not going to transmit or receive any data via Bluetooth, then turn it off. If points Wi-Fi access will also not happen in the near future, then turn off this system too. And if you are in a place where 3G does not reach, then turn it off in the settings and mobile networks.

Geodata or GPS also consume a huge amount of charging, so it is advisable to turn them on only when necessary. You can disable GPS in the settings window in the “Location Services” tab.

Now we need to figure out the amount of energy consumed by the display. After all, the longevity of the battery also depends on it. In the display settings, you need to change the screen brightness to 30-40%. If the weather is not sunny and your vision is good, you can reduce the brightness to an even lower value. In the display settings, you also need to reduce the screen time. The optimal value is no more than 30 seconds. And then the phone should go into sleep mode.

Installed applications consume a lot of energy. And not everyone knows that when you try to close some offers, they simply disappear into the background and continue to consume power. Close applications completely in the “applications” or “application manager” section of the settings. There you need to open running programs and in each running application, click on the “stop” icon. This process is quite lengthy, and programs can be disabled by other, more in a fast way.

You can download it on Google Play free program Battery Doctor. After installing it, you can close all applications running in the background with one click of the “Optimize” icon. The program also allows you to adjust the screen brightness, turn it off and on wireless networks, ringer volume and phone vibration. An additional advantage is that thanks to the Battery Doctor application you can find out the charge level in percentage, as well as the approximate amount of battery life.
