I had 1 bad day after downloading the official release. Drained to 5% in 5 Hours after a full charge with NO use. Kicked it in airplane mode for a half hour, then did a restart. Fully charged and I'm now on hour 23 with heavy use without a recharge and still at 38%. It should settle.
Phone officially sucks . Loses 10% battery every half hour. So how effective can it be in a daily business day when you can't get through even half a day.usless without a good batt life. Can't imagine what would be if I played games on it.
