If the POCO F7 heats up after system update, please refer to the following details:
1. After updating the system, your phone will experience a short period of noticeable heating that lasts for one to two days;
2. This is a normal phenomenon caused by background processes such as APP recompilation, system optimization, and indexing, which temporarily increase the device’s workload. As a result, you can feel the phone becoming warmer than usual, especially during charging or when using multiple APPs;
3. However, once these processes are completed and the system stabilizes, the temperature will gradually return to normal levels without requiring any intervention. This does not indicate a hardware issue.
