What if the Xiaomi Buds 5 Pro runs out of power after upgrading and the charging case cannot charge the earbuds?

Please refer to the following methods to troubleshoot:
1. Put the earbuds into the charging case and wait for about 10 minutes. After the earbuds are charged and activated, take them out and use them again. If the charging case also runs out of power, you can put the earbuds into the charging case and charge it to restore;
2. Check the firmware version of the earbuds to make sure it is the latest version. If the earbuds firmware is not updated, try to update the firmware again;
3. Make sure the charging port of the charging case is not damaged and has good contact. If the port is loose or damaged, the earbuds will not be able to charge.
