Q: Apple Pencil Battery Charge

To see how much charge your Apple Pencil has left, check the Today view in Notifications on your iPad Pro.

If you have not enabled it, tap the edit icon under the today view and enable the battery widget. You can then use the widget to see the pencil's charge state.
