iPhone not charging? What to do step by step (quick diagnostics)
When an iPhone doesn't charge, it doesn't mean an expensive repair right away. In most cases, it's a problem with the cable, adapter, port debris, or software. In this guide, you'll find exactly what to do when your iPhone won't charge at all, charges slowly, or interrupts charging.
The most common reasons why the iPhone doesn't charge.
- Damaged or non-original cable
- Weak or faulty charging adapter
- Impurities in the Lightning/USB-C port
- Damaged connector (dock) inside the phone
- Overheating or hypothermia of the phone
- Worn battery
If the iPhone does not charge „normally“, but only very slowly:
- Use a more powerful adapter (ideally 20W+)
- Turn off demanding apps while charging
- Activate flight mode
- Do not use your phone while charging
- Check the battery condition in Settings > Battery > Battery condition
When is it time for service?
Go to the shop if you..:
- iPhone does not charge even with another cable and adapter
- The port is visibly damaged
- Phone overheats when charging
- Battery condition is well below 80 %
