If the button on the charging case of the REDMI Buds 8 Lite is unresponsive, please refer to the following troubleshooting methods:
1. If the charging case battery is too low or depleted, the button may not respond. Fully charge the charging case using a compatible charger and cable, then try pressing the button again after the indicator light turns on.
2. Dust, debris, or dirt around the button may prevent it from being pressed properly. Gently clean around the button with a soft, dry cloth or a small brush to remove dust and debris, and make sure the button can be pressed normally.
3. If the charging case is physically damaged or worn, for example, due to being dropped or exposed to moisture, the button mechanism may become stuck or damaged, leading to button malfunction. If exposed to moisture, allow it to dry completely.
4. If none of the above methods work, please contact your local after-sales service center for disassembly and inspection.
