What to Do If OPPO Phone Won't Flash Charge
To solve the problem if the phone won't charge or the VOOC flash charge is not working, you may check the phone charging port and connection, restart the phone, and update the system. Read on and learn more about why your phone won't flash charge.
About VOOC Flash Charge
Developed by OPPO independently, VOOC Flash Charge comes out with an intelligent *5-level safety mechanism, offering 4x faster charging than conventional chargers.
When your phone is being flash charged, you will see a yellow lightning sign on the top right corner of your OPPO phone screen and the VOOC tag on the lock screen.
Note: *5-level safety mechanism covers all aspects of the charging process from outlet to phone battery, from the adapter to the port and the internal parts.
OPPO phone flash charging
Your OPPO phone can be flash-charged under the following conditions:
Your phone should be VOOC compatible. Please refer to the actual product.
Charge the phone with the original VOOC charging accessories (including the VOOC power bank).
What to do if your phone won't flash charge
1. Check the phone charging port and connection
Check if the charging port is blocked, damaged, or loose. Remove any debris from the charging port. If the charging port is seriously loose, worn, corroded, or aging, stop charging to avoid unexpected faults such as leakage or short circuit, and send the phone to repair at once.
Check the connection of your phone charging port, VOOC adapter, and VOOC cable, and reconnect the VOOC adapter to the USB port. Make sure that everything is plugged in firmly.
Note: If your phone has a removable battery, remove and reinstall it. Try other VOOC adapters on your phone, or charge other VOOC-compatible phones with your VOOC adapter, and see if you fixed the issue.
2. Check the phone's temperature.
Keep the temperature of your OPPO phone in check when charging. The suitable temperature when VOOC/ Super VOOC is charging normally is in the range of 16 to 45°C.
