Huh? The only thing I've found so far is discussion of people fixing some battery life issues by disabling Oppo's lockscreen.
Battery life overnight for me is spectacular. I lose 4% overnight typically on omni. Battery life "out and about" last Saturday was poor, but mpdecision wasn't running (all cores always active) and as much as I have disliked the interactive cpufreq governor in the past, with a 2.3 GHz, ondemand's tendency to jump to max freq is a little too much - since fixing mpdecision and changing governor to interactive battery life has seemed good in all cases.
But if you want to take a look to evaluate its worth for the Omni project, get in touch with Zeus or Adam on the Oppoforums and ask to get invited into the conversation group.
From what I saw though it reduces the radio and wifi consumption by a good deal (at least on ColorOS).
