Charging issue

Not sure why that is happening however I do have some recommendations that you can try one at a time:

1) Try a different charger/adapter

2) Try a different cable

3) Try and Force Restart your iPhone EXACTLY as shown below and see whether that resolves the issue:

• Press and quickly release Volume UP button
• Press and quickly release Volume DOWN button
• Press and Hold the SIDE button until an Apple logo appears and then release the Side button (Can take up to 20 seconds. (DO NOT release Side Button when invited to Slide Power OFF). 

4) Turn off optimized battery charging by opening Settings ➔ Battery ➔ Battery Health ➔ Optmized Battery Charging, Set this to OFF and test the charging speed. While you are here, check the battery health and peak performance capability listed on the screen.

Two Things:

A. Look Up the Battery Health:

When the Battery Health is 80% or lower, it is time for a new battery.

1. Go To: Settings
2. Tap: Battery
3. Tap: Battery Health
4. View: Percentage

Time for a New Battery?

and...

B. Perform a Restart:

If stuck, try Force Restarting your iPhone. Save any information that need be. Then perform the restart.

Perhaps this is a Faulty Device?:

How new is this iPhone? Is it just now purchased? Note that you have a one-year, out-of-the-box, limited-warranty with this. So, if it is covered under warranty, then see if you can get the screen replaced. Being faulty, it likely would be nothing on you. Ask Apple Support for a new screen.

NOTE: Due to the Coronavirus Pandemic, calls are taking a bit linger to get through. And, that makes sense, because many are at home working out-of-the-house or are taking classes over-the-web, this they have more time on their hands to contact Apple Support. So, it might take a bit to get through to Apple Support. But, just stay on the line, and someone will be with yo
