Apple Pencil 2 won't charge 100% when left overnight on my iPad Pro (3rd Gen) which is charging

I found the Apple Pencil 2 occasionally misreports its charge state - left attached to iPad Pro for several hours, removed and re-attached it reported 0% charge. Unpaired ("Forget this device") and re-paired, instantly at 100%. HTH

I have the same problem, and brought it to the attention of Apple Support. One of the engineering teams within Apple has been made aware of this issue, and are actively reviewing the logs from my iPad to determine what the cause of the issue is. I suspect it is a software bug, as I replaced both my iPad and Apple Pencil and had the same problem with the second set.

I'm having all kinds of issues with my Apple Pencil 2. Even when my iPad Pro 11" is charging, the pencil loses battery power and eventually just dies. Removing it and replacing it makes it charge back up, but most of the time it will not even go all the way up to a full charge.

The iPad Pro 11" has issues too. Factory reset and did not reinstall 3rd party apps, and this thing will not hard reset nor will it Power Off. I have to go into Settings > General > Shut Down to get it into sleep mode.

I've spoken with Apple Support on the phone and even the phone tech said both devices were having some issues. He gave me a support number so that I can make an appointment at the Genius Bar. Just wanted to let you know you're not the only one having an issue with the new Apple Pencil.

My apple pencil 2 wont charge after the software update. Help.

I'm not having any issue with my Pencil 2 being charged to 100% when charging overnight. Reboot your iPad and see if that changes anything.

Press and quickly release the volume up button

Press and quickly release the volume down button

Press and keep holding the power button (hold past the swipe to shut down) until the Apple Logo appears, then let go

You could also try unpairing the Pencil, then pairing it again as another step.
