There are several reasons why your device might not charge, and most can be fixed without any extra support. The most common reasons for a device failing to charge are:
a faulty cable, charger, socket or adapter
dirt or debris in the charging port
third party apps interrupting the charging process
a software update is required
There are a few problems that could be occurring – your device could be refusing to charge altogether, or it could simply be charging really slowly; sometimes so slowly that it’s actually using power faster than it’s gaining it. If you’re experiencing any of these problems, we’ve come up with a few ways to diagnose your battery woes and to help you fix the problem.
