What to do if the phone and the Xiaomi Power Bank 20000 (Integrated Cable) both get hot when charging?

Question

Accepted Answer

When both the phone and the Xiaomi Power Bank 20000 (Integrated Cable) become hot during charging, it is often caused by high power output, environmental factors, or the device operating under heavy load.
If the phone and the Xiaomi Power Bank 20000 (Integrated Cable) both get hot when charging, please refer to the following methods:
1. If overheating occurs, stop charging immediately and allow both the phone and the power bank to cool down naturally for 5–10 minutes.
2. Avoid using the phone while charging, as gaming, video playback, and other high-load activities can generate additional heat.
3. Ensure the charging environment is well-ventilated and avoid placing the devices on heat-retaining surfaces such as beds or sofas.
4. Check whether the power bank’s integrated cable and connector are clean and undamaged, and avoid bending the cable sharply for long periods.
5. Try charging another device with the power bank to determine whether the heating issue is caused by the power bank itself.
6. If the phone supports disabling fast charging, try turning off fast-charging mode to reduce heat.
7. The power bank may heat up more when the battery level is extremely low (0 – 10 %), so consider charging it when it still has some remaining power.
8. If the power bank becomes excessively hot, emits an unusual smell, shows swelling, or frequently disconnects, stop using it immediately and contact customer service for inspection.
