Battery usage after jellybean downgrade Saturday

[racefan25]

This screen show says it all. This is 1 text message and one 1 minute phone call and nothing else. Did not check emails nothing phone was in pocket all 7 plus hours and not used. Look at the screen usage and OS usage for a phone at rest. Seems the phone is not sleeping when not in use. Dug a little more and found the phone is awake a large amount of time even though screen is off and in pocket. I have google now turned off and WIFI off and turning data off did nothing. battery was dropping 1% every 5 minutes it seemed at the very end Battery was at 15% after 10 hours of non use

This really burns me pay top dollar for a phone that you have to turn off every feature off to have battery last more that 10 hours on idle. I WANT ICS BACK NOW

I recommend investing in BetterBatteryStats to check for wakelocks.
You can set a custom reference point to check for partial wakelocks.
It's not free, but what I recommend.
I am sure there are other free apps that others can recommend also

Edit: your thread title...do you mean "upgrade"?
Here is a good read about it too:

I have read the factory reset post and hope to not have to do all that . I will look at the
betterybatterystats app

Its not THAT bad but id root, back up apps and data, reset then unroot.
Do you find that JB performs better and is it 4.1.2 ...or 4.1.1 mate

P.s. is there anythin that could be waking your phone?
U tried Cpu Spy to see if it hits deep sleep and Better Battery Stats or Gsam to see whats eating?

Low signal is a battery killer too - which you seem to have.
