happy to report that battery life on 4.2.2 is stock-like.
after 25 hours with Wifi on, bluetooth on, ~2hrs on-screen time, down to 15%.
also, no additional mods, battery saving apps, or kernels - just the ROM straight up!
the key for me (I think), was after installing the ROM, I let the phone automatically power off (drain down to 0%). I then plugged it in (still off) until it reached 100% (took about 2 1/2 hours), then I turned the phone on.
right now, I have 2 small reservations (which appear to common among all 4.2.2 ROMs): audio record on camcorder still not as strong as 4.1.2, and when a received call ends, the phone screen does not show up after I pull the phone off my ear. I'm sure there is a build.prop setting for that.... just need to research that....
but really really nice work tim!
I probably would check out 4.3, but from what I read, the only significant feature of 4.3 over 4.2.2 is better bluetooth connectivity, and my phone connects just fine to my car for calls.
I'll sit back and wait for KitKat (4.4) to arrive....
