Wow, I'm going on 12h 40m and have 40% left.
I have bluetooth on (Connected to headset)
Wifi on (Connected to work Wifi earlier and home currently),
GPS on (Did some google map searches earlier looking for a micro hdmi cable provider)
4G off (Poor coverage atm)
I've been installing apps, streaming pandora < 30 min today, surfing internet (prob around 1 hour worth), prob close to 1 - 1.5 hours of phone calls..
I have advanced task manager installed, but auto kill is off and haven't been using it to kill apps. I'm still new to the phone/operating system, so I don't have a lot of third party apps that I'm running yet, but have tried out a few to solve some issues I've run into and have installed some suggested on this site.
What apps to you tend to use? Since you have everything off, I'd imagine it's an app issue, heavy use (Compared to myself) or a bad battery maybe?
