Apple Pencil 2 stops charging after a few seconds

As the second generation Apple Pencil charges successfully with other compatible iPads, you may reasonably conclude that the Pencil itself is charging normally.

This would lead to the assumption that your iPad, or its inductive charging dock, is not working as it should. Begin with a forced restart of your iPad, as this will often clear an isolated software issue:

Force restart iPad (models with Face ID or with Touch ID in the top button)

If your iPad doesn’t have the Home button, do the following:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

If the problem persists, given the nature of the fault, you would be best advised to visit the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to test and assess your iPad and Pencil. Here you will be best able to explore your available remedies and options:
