Not to be labor the point, but I do think battery life has taken a huge hit after the update. I have followed a bunch of the advice and nothing yet, no improvement. And I did the factory reset a few times as well. The latest is turning off Google Now which has been disappointing anyway, so what's the point of leaving it on? [...] We'll see if that makes a difference.
I'm still waiting to hear from 1 person with bad battery life that did a hard reset, did not install any apps, ran their phones for a few days, and still have horrible battery life.
Anyone have any idea what could be causing "Android OS" to be kept awake for over an hour? I also installed System Monitor and it only confirmed that "system" was using my battery, but no more details beyond that.

I installed GSam about a week or two ago to check what was waking my phone constantly. While my screen is off(probably an average of 35-40 minutes per hour), Maps(I'm assuming for Google Now) wakes my phone an average of 75 times an hour for an average time held awake around 7 minutes. That is just a bit ridiculous and I wonder if it is supposed to be running like that or just a glitch that needs to be worked out. I have observed this both on the stock JB ROM and MeanBean.
Same here. I guess it's expected, but I don't know why. It might be an interesting experiment to try disabling the Maps app. I wonder what would happen...

I mentioned this in another thread, but I did a hard reset after having terrible battery life after installing the JB update. I managed to go throught 35% of my battery in less than 3 hours with the phone in power saver mode and in standby. When I reinstalled my apps I left a few rogue apps off that Carot was picking up on and I notice a slight bump in battery life.
I think the problem may be that JB is some how causing rogue apps to run/pull data more that they where before the JB update.

Do you have location history turned on? It is on by default if you have Google [Spy] Now on (has been discussed many times in many threads)
No way. I've been on your side with the anti-Location History as i already knew how much of a drainer that is from ICS. My battery life isn't bad by any means. Just trying to pinpoint all this cpu waking. I'm going to turn Google Now off tonight and see what the difference will be tomorrow.
It will be interesting to see if you find any difference with it on or off, with location history already off. Our premise might be that there should be no difference... if there is, then things will get messier (could be confounds, combinations issues, something else that Google [spy] Now does, computational errors, unrelated apps, etc)
