What model of phone? Did you replace the charger/cable/AC block as well?
Yes I did replace the charger and the AC block as well.
It sounds like you have tried everything.
I have a few more questions for you:
- Have you tried a different outlet?
- Is your phone updated to the latest software version?
- If the phone is still able to power on, can you please uninstall all applications that were downloaded right before the phone stopped charging?
Ultimately, it sounds like a warranty exchange may be in your near future if you haven't already taken that route.
Just wanting to check in and see if you had a chance to try the steps above!
