The other day I was shocked to get an alert notification on my iPP when I turned it on saying that my Pencil was down to 5% charge! I will periodically check the pull down status from my iPP when using my Pencil but guess I must have my settings configured to receive banner alerts.* I liked that my iPP knew that (haven't been drawing with it this last week). It's not like it takes long to charge but I appreciated the alert all the same and better than finding it completely discharged. *just checked notifications under Settings and there isn't anything for the Pencil.
