After i did the update and went through a few charge cycles, mine is not bad. You can't expect to watch movie, use 4g and wifi when you can, use the gps for maps and directions AND talk/text all day and have the battery last that long. I bought the mugen 1800 mAh because it was slim and i didnt want the bulk. Try a few more charge cycles, my battery life is improving and i try to run the hell out of it whenever i can.
By 'not bad', how many hours are you talking?
When I say I turn off everything, I mean EVERYTHING. No anything.
No background data, no syncing, no gps, no 4g, no wifi, no running tasks(ATK). I don't even touch it and it only last 10 hours.
If I used my phone moderately it would last maybe 8 hours. In contrast my old blackberry with the same usage would last ~48 hours.
Are your awake and active times close or extremely different?
I noticed my phone isn't sleeping correctly which is probably a big part of the issue.
My guess is some apps aren't following the rules. Last night I uninstalled EVERYTHING. Not 1 aftermarket app.
Only thing running is gmail since it's required. And now it's sleeping.
My awake time is 10 hours and my active time is only 20 minutes. The last week they've been almost identical.
So today I'm going to test battery life with sleeping working. My bet is it gets 2x the life. We'll see.....
Edit 071110:
Battery life with sleep working is MUCH better. Around 26 hours.
I also found one rouge app. 'Good mobile messaging'. It's the app that syncs to my exchange server.
It doesn't let the phone sleep at all. Even when I turn off background syncing!
Next I'm testing leaving GPS, and Wifi on with sleep working(Good mobile is uninstalled).
