No response after plugging in the charger is one of the most common problems iPhone users report. Sometimes the cause is a dirty charging port, other times it's a damaged cable, battery, or motherboard failure. In this guide, we explain, Why isn't my iPhone charging, how to diagnose the problem yourself and when it's worth taking the phone to a professional service center.
Most common reasons for iPhone charging problems
- Dirty Lightning or USB-C port
This is definitely the most common cause. Dust, fabric fibers, and other debris get into the port from your pocket or purse. After a while, the plug doesn't go in all the way, which prevents your phone from charging.
Symptoms:
- The charger falls out of the socket.,
- charging only works at the right angle,

- What should I do?
- Do not use metal tools. It is best to gently clean the port with a wooden toothpick or take the phone to a service center where it will be cleaned professionally.
2. Damaged cable or charger
Not every cable works correctly with an iPhone.
Problems can be caused by:
- damaged cable,
- Damaged ends,
- Cheap non-MFi certified replacements,
- Damaged power supply.
How to check?
Connect
- another cable,
- another charger,
- computer,

- frequent plugging in the cable.
Symptoms:
