Why does the REDMI Buds 8 Lite overheat during charging?

Question

Accepted Answer

If the REDMI Buds 8 Lite generates some heat during charging, please refer to the following methods to troubleshoot:
1. Lithium batteries naturally release some heat while charging. Since the earbuds are small, the heat dissipates slowly, which can make them overheat. Always charge in a well-ventilated, room-temperature environment.
2. Using non-original chargers or chargers with excessively high power can provide unstable current, leading to overheating. Always use the official charging cable and a compatible power source.
3. If the earbuds do not make proper contact with the charging case, unstable current can generate extra heat. Check for dirt, oxidation, or foreign objects on the contacts, and clean them to improve charging safety.
4. Charging in a hot environment prevents heat from dissipating efficiently, which can cause noticeable warming. Charging in a ventilated, moderate-temperature area is recommended.
5. If the earbuds overheat, immediately stop charging and contact the after-sales support for repair or replacement.
