Causes and solutions:
1. Fast power consumption in a low-temperature environment:
At low temperature, the performance of the lithium battery deteriorates, resulting in increased power consumption. This is normal. Wait until your phone returns to normal room temperature.
2. Fast power consumption with 5G network:
When your phone uses the 5G network, the 4G network is turned on simultaneously, so the power consumption automatically increases. You can turn it on or off according to your needs by going to Settings> Network & Internet> SIMs> Preferred Network Type.
3. Fast power consumption after upgrade:
Power consumption increases after you upgrade your phone. Charge for one night after the upgrade. Alternatively, your phone will recover by itself after 2-3 days of normal use.
4. Check the power consumption details:
Go to Settings> Battery> Battery Usage, and check the power consumption details of corresponding programs.
