I have a Samsung S5 cell phone. It just now stopped charging. ??
I have tried at least 3 different charging cables, and 3 different
chargers.
I also removed the battery and did a factory reset.
Anyone have any other ideas?
Thanks.
Charger, cable, damaged USB port in the phone, build-up of dirt/lint
in the USB plug or socket. Faulty charging circuit in the phone, or
maybe the battery is completely dead.
The most likely cause is a damaged USB port in the phone.
Use a multimeter to check the battery voltage. Clean out the
USB socket using a toothpick. Make sure the battery contacts are clean. Inspect the USB socket for damage.
If all else fails, you probably need a new USB port. You can buy
a complete PCB with socket for just a few re4/-u/$. You will need to
dismantle the phone to get at the socket. Plenty of guides on
YouTube.
Good luck.
