Since you've already tried restoring and setting up as new, I'd def. take it to an apple store.

Any tips mate if I do?.

I bet they hav peeps goin into the store all the time complaining about the battery life. But then, the battery stats I'm getting is not on!
 
After jailbreaking yesterday and doing a full charge my stats are:

Battery 38%
Usage 3hrs 18 minutes
Standby 4hrs 50 minutes
 
Anyone know why battery usage stats don't appear after jailbreaking?

Do a full reboot once all your tweaks are installed and then charge to full ... it will appear ... Note that whenever you respring, those stats get mnessed up

I know it has been said numerous times but I'll just reiterate it ...

1. Best is to take a backup locally in iTunes (Disable iCloud Backup)
2. Do a DFU upgrade to 6.1
3. Setup as totally new entering your apple id but dont enable icloud just yet
4. Once on hoome screen, restore your backup
5. If you have exchange account, delete it after restore and setup again as new (Or you could delete before backup altogether).

Here are my stats with Full Video Playback (Back to back episodes) + voice calls + whatsapp + sms + FB + Music + iCloud (All push on)

5 Hours atleast was all video!
