(For stock, non rooted)
1) Backup all your data, photos etc.
2) Under settings , look for factory reset. (This will wipe all data)
3) Setup your phone etc but dont drain the battery flat.
3) Charge phone overnight ( With phone turned off )
(Rooted)
1) Go to CWM
2) Factory reset , wipe cache partition , wipe davilk cache
3) Turn on phone, let phone settle for at least 5mins
4) Setup your phone etc but dont drain the battery flat.
5) Charge phone overnight ( With phone turned off )
If all else fails... reflash another rom
Your situation is very similar to my friend's S3. Her method was painfully charge it to 100% before she unplug the phone. After that it was working fine. It's probably due to the battery stats. I think her phone's battery stats kinda screwed up after the JB update. Anyway she managed to solve it.
The battery stats will reset once charged to 90% (if I remembered correctly.) Maybe before doing all of above, you can try to charge your phone to 100% and see if there are any problems after. There'll probably be people who will tell you to wipe battery stats on CWM but pls dont listen to their [email protected]#$.
Just try what i suggested and see if it helps.
Cheers

Then I suggest u charge the phone to 100%. Yes it will take ages but that's how my friend solved hers.
