Q: Why does the phone get hot when it's charging?
A: This is normal, because the phone will generate some heat when it is charging. However, the main reasons for the heat are as follows:
1. The charging speed will be faster when the phone power is low, the wall charger will output 9V high voltage, and the phone will generate heat because of the voltage converting process.
2. There are too many programs running in the background of the phone, causing the phone to run at a high load and generate more heat.
