I see some of the posts about battery life. Seems most are 4 to 7 hours of usage. I also see a couple that are getting 10 to 12 hours of usage. One in particular is 4% left, 12 hours usage, I day 19 hours standby. Said they did the following: Listen to almost 2 hours of music. But played jetpack game and need for speed too. Again I have everything turned on, everything, except bluetooth and exchange. Best results i have had yet. Mine is running at 9% left, 4 hours used, 2 days 10 hours standby which certainly is not great i my opinion... How in the world could that be compared to most of the others it just seems to be a huge disparity.
