My SGS2 arrived yesterday.
after reading this forums for the past couple of weeks, since its arrived ive kept and eye on the Andriod OS battery usage.
When i went to bed last night, the phone had been on for about 5 hours, and the Display usage was at about 70%....which seemed fair seeing as out of that 5 hours, id had the screen on for about 4 hours of it.
however when i woke up this morning, things had changed. as of thisafternoon (right now) 16h 25minutes up ive 31% battery remaining, Andriod OS 29%, Display 25%, Maps 21%
concidering im sick as today and have spent most of the day sleeping, i havnt used the display bugger all.
Everything except bluetooth has been turned on the whole time. - im guessing having GPS on is why map usage is so high? Ill do a Kies update after the phone has gone completely flat.
