The Xiaomi Buds 4 Pro can't be charged.

If the Xiaomi Buds 4 Pro can't be charged, you can refer to the following troubleshooting steps:
1. Check whether the charging case has power. If the charging case is not charged, charge the charging case and then charge the earbuds, and try to turn on the earbuds after charging;
2. Charge the earbuds for a longer Period. Sometimes, if the earbuds have not been used for a long time resulting in low power, they need to be charged for a while;
3. Check the charging contacts on both the earbuds and the charging case for any signs of damage or debris. If the charging contact at the bottom of the earbuds is dirty, wipe them gently with a clean, dry cloth to remove any dirt or residue;
4. Try using a different charging cable and charger to see if the case can be charged. If it can be charged after replacement, the charging cable or charger may be faulty;
5. Try performing a reset by opening the earphone box and putting the two earphones into the box, keeping the box open >> Press and hold the function button at the bottom of the charging box for 10 seconds until the indicator light turns orange >> Wait for the indicator light to change from orange to white, then turn on the Bluetooth of your phone to pair with the earbuds;
6. Ensure that the firmware for your earbuds is up to date as outdated firmware can sometimes cause charging issues.
