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.

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.

Yes. Do not charge after liquid exposure until the device is inspected.
