I am having terrible battery back up, just 10-12 hours :-/ I tested twice 
-I have 4.3.3 JB'ed
-Hardly installed apps, some 25 in total
-Never run any app in back ground, used Home button to close them.
-No games more than an hour while testing. That too simple games, Non HD
-Wifi, 3G, Location service disabled
-Brightness some 30%
-ONLY one push notification, my email. Rest all notifications disabled.
-two or three calls of just 2-3 min each. No SMS
-No vibration mode
So is there any problem with my iPhone battery ? [It just a month old]
I didn't do any tweaks ! I just installed SB Settings. That's the only app I am having from Cydia.
Another test :
- disabled everything; turned airplane mode on, wi fi off, gps off, notifications, push off. Set the brightness to some 50-60 %. Initially battery level was at 61% I saw a movie in air player for just one hour, the battery reduced to 43% ! [The movie wasn't ripped for iPhone, the air player can play 600MB avi directly ] that means if I watch full length 2 hour movie would it take almost 40% of battery ?
even on flight mode with wifi and gps disabled
