Alright guys, here is how it goes. I have tried stock battery for a week, no matter how I save the battery, it wouldn't go past 6 hours. Bought Seidio 1750, it went past around 10hours mark, but usage time is only about 3hours. So I RMAed the first one, got a replacement, same result. I have been taking notes at this situation, with all my apps installed AND after factory reset, they are the same, so I can say it's not the apps. My usage pattern is the same, for about 4-5 hours a day, I would set my exchange mail to sync every 15mins, then I would turn it off. During the day, I would manually sync Newsrob a few times. Gmail is on. Wrote a few short emails, a few texts and 15mins of XiiaLite. 3G is always on, no GPS, no bluetooth. Screenshots attached. Please help me. Is it possible for the phone to drain battery like that? Or do I really have 3 bad batteries??
