Why the phone runs out of battery quickly and how to fix it: 5 tips

We understand, what to do, if the phone runs out of battery quickly, and we help to find out the causes of this problem.


1 Reduce brightness, screen resolution and refresh rate

One of the main reasons, why is the battery on the phone running out fast, this is a high brightness screen. It is the display that consumes the most energy, and the higher the resolution and brightness, the more the smartphone will be discharged.

To save charge, Set automatic brightness detection This feature is available on all modern smartphones and tablets. Also, in the device settings, you can select the smart resolution option or manually set a lower resolution to save energy. If you are using a device with an AMOLED screen, activate the dark theme: these matrices do not waste energy on highlighting black pixels.

Also on some new models, you can adjust the refresh rate of the screen: for example, 120 Hz or 60 Hz. The higher it is, the faster the smartphone will be discharged. What is the need for increased display coverage on the phone, we told you in a separate article. So, at 120 Hz it is much more convenient to play and work with the application interface, but if you want to extend the working time of your smartphone, then it is better to choose a low frame refresh rate.

Also in Android, you can disable all kinds of animations and visual effects of the system. But this will save quite a bit of charge, therefore, it does not always make sense to give up a beautiful visual. All settings for disabling animations and other ‘decorations’ are in the settings section ‘Special Features’ ‘Additional visual Effects’.

2The battery on the phone runs out quickly: disable unnecessary applications

Why does the new phone’s battery drain quickly? It’s not all the fault of some energy-absorbing viruses, and the programs, installed on a smartphone. There are often too many apps running in the background, while using the Internet and sending notifications. For example, constantly working against the background of FaceBook will very quickly drain the battery of any smartphone. Not to mention the forgotten tab with an active game.

Fortunately, the appetites of applications can be reduced. At first, check it out, which programs on the smartphone can run in the background. This can be found in the settings in the section ‘Applications’ - ‘Launching applications’. On Android, you can adjust the startup parameters manually, by prohibiting the work in the background and the indirect launch of the program by other applications.

3 dIsconnect unnecessary connections and services

The battery will discharge quickly, if wireless technologies like Bluetooth, Wi-Fi and GPS are constantly used. Battery power is actively consumed by applications, which access these services in the background.  

  • Operation

To save charge, GPS should be disabled, if you don’t use maps and other programs, which is important for your geolocation to work correctly (for example, weather apps). It is also worth giving up constantly on Wi-Fi if it is active, the smartphone will continuously search for free networks to connect. Although Bluetooth uses almost no power (especially in the latest fifth version), it is also better to turn it off, if you are not currently using a fitness bracelet, headphones or other wireless gadgets.

4 Check the battery capacity

If the smartphone is charging fast and discharging fast, we can assume, that his battery has a very small capacity. Over time, the batteries lose it due to frequent recharges and this is quite a normal process. However, in one or two years of operation, it is quite difficult to significantly ‘plant’ a high-quality battery, but for a longer period it is quite realistic. The problem can be solved, replacing the battery with a new one.

Sometimes it happens, that even a new battery is quickly discharged in the phone for example, after replacement in a private service. If you have optimized the application and system settings, but the battery still loses charge quickly, this may indicate that, that the service either did not change it at all, or they put a less powerful battery in the phone.

To check the battery capacity, you will need a special USB tester, which connects to the phone using a wire. Such a gadget can be bought on Aliexpress for about 300 rubles. You can also measure the capacity using the AccuBattery controller app for Android or Battery Life for iOS, by activating it during the charging process. If the actual battery capacity is lower than stated by the manufacturer, it needs to be replaced. By the way, it is no longer safe to use a battery with a wear of more than 30%.

5 Shorten the working time of your smartphone

As strange as it may sound, but the smartphone can quickly run out of battery due to, that you use it all the time. You can disable unnecessary services and applications as much as you want, but if the gadget is in your hands all the time with Instagram or YouTube videos enabled, it will be discharged. Applications consume different amounts of energy: games and videos can fairly be considered the most voracious. Also, the charge is quickly spent when working with the camera, for example, if you are constantly photographing something.

If you don’t have the ability (or desire) to put the phone aside, then you can extend its working time with the help of powerbank. Today it is easy to find sufficiently powerful and compact models with fast charging support on the market, which will cost 1-2 thousand rubles for example, Xiaomi Mi Power Bank 2 with a capacity of 20,000 mAh.
