What to do if phones drain battery quickly?
The battery drain quickly on the phone is highly related to usage habits and the environment. Different usage environments and scenarios can affect the power consumption of a phone to varying degrees.
In low-temperature environments, the electrochemical activity of lithium ions in the phone battery deteriorates, which is an inherent characteristic of lithium batteries. Reduced standby time is a normal phenomenon.
To ensure battery longevity, phones have a low-temperature protection mechanism. When the temperature is relatively low (approaching or reaching 0°C), the phone will experience power fluctuations/jumps. It will even automatically shut down or fail to power on when the battery level is low (around 30%). It is recommended to charge and use the phone at a more comfortable ambient temperature.
If the local temperature is normal, you can try the following actions:
1. By accessing [Settings] >> [Battery] >> to see the power usage, you can determine whether fast battery drain is caused by power-hungry APPs;
2. Check if the phone or tablet is charging properly, and try to use the original charger to fully charge the device before observing usage;
3. When a new device is first used, background processes such as cloud sync, MIUI compilation, and APP compilation will automatically start. These processes can lead to fast battery drain and heating, however, they will cease after a few days. Compilation is done to enhance long-term performance and make the system smoother. This process only lasts for a short time, so please observe the device for a while.
If severe battery drain persists, it is recommended to contact the local after-sales service center for inspection.
Other factors that can affect phone battery life are as follows:
1. Poor signal strength: When the phone is in an area with a weak signal, the communication system consumes more power. It is recommended to switch airplane mode on and off in a well-covered signal area to see if battery drain issues persist;
2. 64-bit applications: Since 2023, Arm architecture CPU cores must use 64-bit. 64-bit applications show significant improvements in power consumption. You can check for 32-bit applications and upgrade to 64-bit versions through the Play Store;
3. System updates: After a system update, the phone compiles the newly updated code, which consumes system resources and can cause temporary battery drain and heating. This process lasts 1-2 days and is considered normal;
4. Google services: Some phones come with Google services pre-enabled. If no Google account is logged in and no applications use Google services within 7 days, the built-in Google services and functions will automatically turn off. If you don't need Google services and notice higher battery drain in the initial days, you can manually turn off Google services;
5. Social applications: If battery life is poor during the use of social APPs, it is due to weak network signals or background applications sending/receiving data;
6. Dark mode: Using dark mode in low-light environments can extend battery life;
7. Clear background APPs: Clearing background APPs that are not frequently used can reduce device battery consumption;
8. Adjust brightness settings: The brighter the phone screen, the higher the battery consumption. You can switch on the auto brightness to optimize battery life;
9. Currently, the smartphone industry uses lithium-ion polymer batteries, which inevitably experience lifespan degradation over time. Additionally, battery degradation is significantly influenced by usage scenarios. You can first try performing a full charge and discharge cycle to recalibrate the battery meter and restore battery performance.
If none of the above can resolve the issue, please contact the local after-sales service center for further assistance.
