Safety and data note
If the phone was wet, gets hot, smells unusual, or has a swollen battery, stop charging it and seek qualified help. Back up data before resets or restore attempts.
Quick answer
When an iPhone will not charge, the problem is often cable, adapter, debris, software, battery, or port—not always the charging port itself. Work through the simple checks before paying for repair.
Most common causes
- Damaged or uncertified cable
- Weak adapter or outlet
- Lint in the charging port
- Moisture warning
- Battery failure
- Charging port damage
Step-by-step checks
- Test another outlet and power adapter.
- Use a known-good cable.
- Inspect the charging port with a light.
- Restart the phone.
- Try wireless charging if your model supports it.
- Stop charging and seek inspection if the phone gets hot or was exposed to liquid.
| Outcome | What it means | Next step |
|---|---|---|
| Issue resolves | The problem was likely accessory, settings, or software related. | Monitor for recurrence and back up the device. |
| Issue repeats | Hardware, battery, storage, or board-level failure may be involved. | Get a diagnosis before spending money. |
| Phone heats up or was wet | Continuing to charge can make damage worse. | Stop charging and prioritize data safety. |

Frequently asked questions
Why does my iPhone only charge at an angle?
A loose cable fit can be caused by lint, worn cables, or port damage.
Should I replace the battery or charging port?
Diagnosis should come first because both can create charging symptoms.
Can water damage cause charging problems?
Yes. Do not charge after liquid exposure until the device is inspected.
