Google Nexus 7 battery life test

How is Google Nexus 7 battery life? Nexus 7 has 4325 mAh built-in battery. Based on Google official specification, Nexus 7 can perform 9 hours of HD video playback or 10 hours of web browsing or 10 hours of e-reading or 300 hours of standby on full charged. However, I am not getting this kind of battery life on my Nexus 7. Of course, most of these specs have no background applications running while we have in real life. So my Nexus 7 battery life is shorter…

Screen time on

I am still running stock firmware on Nexus 7 (with root access). No other modification yet. Not much application installed as well. But I do face several wakelocks and need to time to troubleshoot. Or I should try out custom ROM instead. Anyway, the biggest battery eater is Nexus 7 IPS screen. So keeping display backlight at minimum should help to improve Nexus 7 battery life a lot.
