My phone won’t charge by cable

If you already tried (to no avail) all the steps provided in this support article:--> If your iPhone or iPod touch won't charge , it could be a hardware (battery? other internal component?) failure but we, just users like you, cannot diagnose that issue remotely, sorry.

I suggest that you make an appointment (*) and have your device inspected at an Apple Store or AASP (Apple Authorized Service Provider) among this list:--> https://locate.apple.com/choose-country-region . After checking it out, they'll give you all the available options.

Regards

Giulio

(*) You can do it:

• Online:--> Genius Bar Reservation and Apple Support Options - Apple;
• Contacting a local Apple Store or AASP among the list provided above;
• Using the "Apple Store" app, available and downloadable from AppStore.

Remove any debris from the charging port on the bottom of your device. Restart your iPhone or iPod touch. Try a different USB cable or charger. Make sure that you have the latest version of iOS.
