Hi Sudtheapple,
We want to start with making sure the battery widget and charging status when connected to your iPad are reporting the same information. When this occurs, check the status of the battery using both of the steps below:
"If you have Apple Pencil (2nd generation)
- Attach your Apple Pencil to the magnetic connector on the long side of your iPad."
"To see how much charge your Apple Pencil (1st or 2nd generation) has left while you're using it, check the Today View on your iPad. Just swipe from left to right on the Home screen or Lock screen."
Is the battery level the same in both places when this occurs?
If not, let's start with ensuring that your iPad is updated to the latest version of iPadOS. Check out the steps here for help: Update your iPhone, iPad, or iPod touch
We look forward to hearing the results.
Cheers!
