Why isn’t my Amazfit GTS charging?
1. Check if the USB port, charging adapter, outlets or the charger is faulty. We recommend you charge it with your PC or phone charger (Rated input voltage: DC 5.0 V Input current: 500mA).
2. Check if the charging contacts on the back of the GTS or the charging pins on the charger are dirty.
If they are dirty, please use a cotton swab with rubbing alcohol to clean the charging contacts and charging pins. Please clean them thoroughly and make sure that no debris from the swab is left behind. Then, wipe with a dry cloth or tissue before charging.
