I been on AOKP and cant really complain about my battery life .The other day I had
very light use,actually the lightest use I have had on my GN .
I had my monments of use as you can see from the graph when it flatlines to where it takes dipps, or is gradually sloping downwards.
Most of the use came from viewing my emails,sms some bluetooth use,and light web surfing ,light use of tapatalk, a few phone calls, but still kinda surprised me that I got 31 hrs out of stock battery before it got down to 10%
