Battery drains in 4 hours after JB upgrade in sleep mode

[rukol]

Hello I upgraded my phone to JB and made factory data reset and after that my battery drains in 4 hours (90% of that time telephone was in sleep mode)

Try repairing with SUS.

Hmm seems like you were on the phone for some time?
I do suggest trying to repair with SUS or PCC.

My battery life is not so bad.

Also I noticed the telephone and charger started to heat significantly during charging or when connected to computer

I flashed via sus and downloaded my phone operator settings and it solved problem with draining battery in sleep mode. Now testing how it works in active use

did you turn on the new Stamina Mode, my XP's battery becme great today, I used it for doing some facebook, playing walkman music and playing candy crush  and my Phone prolong for 18hours and counting, 35% remaining.

I have the sample problem neel_bajaj, mine drains in 9 hrs too, android OS alone taking 30% of the battery which i think is the culprit, have a look at my screens:

If you already have found a solution please let me know

my phone was just used for whatsapp like say 5 mins. rest staminamode on and in 41 mins i lost 5% earlier i would loose just around 2% max for the same stuff. i think there is some issue with the stamina mode. and one more intresting thing from 100% to 99% in a single minute again the same thing stamina mode on. and i dont have much apps installed, and have already disabled facebook , weather widget all the extentions etc.
