Begin by checking your charging cable to see if it works with any other devices, or trying another charging cable in the same device. This will let you determine whether the problem is with the cable or with your phone. Also try turning your phone off and then powering it on again.
Make sure to also check the charging port on your iPhone. It may be blocked with lint buildup or other debris. If there is lint present, carefully and gently remove it with a straightened paperclip.
If your charging port is clear but you continue to have issues charging your iPhone, make sure software is up to date. To do this, go to Settings > General > Software Update or simply connect to your computer’s iTunes.
Finally, you can try to fully restore your device. To do this, back up the data on your iPhone and erase all content and settings. Read our instructions on backing up your device here. Learn how to reset your content and settings here.
