What makes you think it is "stuck"? Perhaps your battery is at 100%?
Troubleshooting iPhone Charge:
Visit the following links for tips on troubleshooting this...
I. Try what is on this Link: If your iPhone, iPad, or iPod touch won't Turn on or is Frozen - Apple Support
II. View the Battery Health:
Apple recommends you get a new battery, once the Battery Health reaches 80% or lower. When the Battery Health is 80% or lower, it is time for a new battery.
- Go To: Settings
- Tap: Battery
- Tap: Battery Health
- View: [the percentage]
- Is it 80% or less? If so, it is time for a new battery.
III. Perform a Restart:
Try Force Restarting your iPhone. Save any information that need be. Then perform the restart.
