I have the same issue. Pencil only charges to 5% and takes 5x the amount of time to charge 1% then it did beofre I updated. Emailed Tim Cook's public email account and got a phone call back from his office. Very nice and scheduled a phone call with a senior engineer team. He called again later and said they could only help if I was running 10.2.1 and not a beta version of 10.3. Ordered a converter to charge from the wall, they want to hear back if the pencil charges from that so they can narrow down their search for the bug.
