PR1.3 changed some battery charging stuff. The N900 now consumes an extra 80mA or so when connected to wallcharger. This extra has always been present with charging from a USB Host. As a result, if installed apps or cellular communication also cause alot of power consumption, the end of charge detection might not work, and it instead might settle at 98% or so. As we know from before, the battery meter isn't accurate at all, so /please/ don't stare at it or make any conclusions from it...
