It's working very nicely with my n7 on their PA nightly of 4.2.2

Just showing you my battery backup. For people wondering about 4.2.2, this is it completely stock.

I've got very great battery usage, always had WiFi on

I just can't seem to get such great battery life. I'm almost 13 hours on battery with only 1 hour and 18 minutes of screen time and my battery is down to 68%. For some reason Android OS is using 40% (the screen is using 40% as well). I'm in the same boat as you in terms of wi-fi always being on, but I'm on M-Kernel and a custom ROM rather than stock. I really should give the stock kernel a go and see how that manages.

Other things can have a negative impact on battery life, I do have tons of apps, but I always manage which ones are running. Also clean installing a ROM is always safer and will probably give you some better battery life due to everything being clean. Many apps do have instances of running in background so it is helpful to check every now and than.

Also disabling GPS will give you some extra time per charge. I always disable it. And I keep WiFi location enabled.

Yea, I already do most of those things. I think my current ROM/kernel setup is just particularly bad as I drained 23% overnight whereas I normally only drain maybe 4 or 5%.

Sounds like a bad setup. I can get about 1-2% battery drain overnight (on average)

Definitely. Thanks to your pictures I might even just go back to complete stock android and see how that fares for battery life.

Well, after a little trial and error I've finally got this thing pinned down. I'm already at about 8 hours of screen on time (device on about 17 hours) and still have 24%. At this rate I should be able to get 10 hours of screen time no problem. Unfortunately I had to reboot at one point and it stopped logging screen on time so I can't really back it up with pictures
