I’m judging the new Pro by its standby charge when not using it. With the previous pencil I could leave it for at least a full day, usually more, after charging to 100% and it would remain on 100% if not used. The Pro version drops about 5% over a 24 hour period when not used. Not completely unexpected and may be due to it being enabled for the Find/devices app. I haven’t checked to see whether removing it from Find would change battery usage in any way. Curious if any others have noticed a difference if they had the previous versions.
