Conserve batt? First, are your OPO rooted? If yes then easy, as you know Android are meant for enthusiast who like to tweak their phone according to their preference.

For me, I'm running stock kernel. So basically I just denied the Google Play Service wakelock, plus Xposed Lion Tamer (previously know as unbounce).

Basically to me, I charge my OPO 2 day once with 35-40hrs usage on 5hrs SOT. Compared with my previous N2 its really heaven and earth.
