I agree, the battery life after four days of having the phone has not gotten better. I'm not a super user of the device, I stream pandora for a total of one and a half hours using a bluetooth headset and use Advanced App Killer to close out apps that are still running. I've set my exchange and hotmail intervals to 30 minutes and still have to charge the device at night and via my work PC during the day.
I love the device, I hate the battery life. It's worse than the Palm Pre.
Not that I suggest returning and exchanging devices ...
However I was having problems with the phone. Google Talk wouldn't work (it would open, load, and shut immediately), same with Gmail. I went to the store last night and said, I would have removed and reinstalled the apps, but they came standard with the phone, so I cannot. And they're not working.
They replaced the phone, and I've re-set up everything as it was before ... and now the phone's battery life is FAR superior. Yesterday, I didn't make it to noon without needing a recharge. I have about 80% left from a full charge this morning.
Maybe there are some "bum" units?
I will report back. I'm not sure the phone will ever have superior battery life, but this unit is a MAJOR improvement over the phone I got on Friday.
