Spoilers: a very impressive +3 hours of screen time by using dark themes instead of bright ones on SAMOLED.

Minor tangent: I'm not sure how he defends his contention that SAMOLED > LCD by noting that he didn't test anything but SAMOLED in the comments. I realize he wasn't testing anything else and I'm perfectly willing to believe that SAMOLED is more efficient but he still claimed X and when asked for evidence punted.

Sadly, the Android Modding community is usually short on throughly testing findings in a scientific way that goes beyond anecdotal evidence. When you inquire about such things or comment, you either get indifference or at worse, hostility from those that start to think you're better than others for wanting to find out the truth from statements. Some users start to confuse curosity and questioning with outright hostile interrogation and lay on comments like "if you don't like what this guy is doing, then don't use it or read it." Sure there are trolls that really do cause problems, but those that honestly want real answers or to help get thrown in with them at times.

Granted that it's not all like this as some groups out there and developers really do care about such things (like Cyanogenmod). However, that's typically not the mode of operation. For example, kernel modders that think it is a good idea to disable fsync by default. On top of that, they generally do not give an option to enable it for end users. Result was lots of data corruption when people pulled out their batteries.

This is just my observations from being heavily into the modding community for around 2+ years helping to administer one of the larger modding forums. I try to push for factual information as much as I can and to lead by example when possible through any code or mods I might publish, but the community is pretty set in its ways still. I do think my efforts aren't in vain when I get the occasional positive feedback from users, so it keeps me going. However, there are just too many non-developers mixed in with a minority of actual developers and end users cannot seem to discern between them.

>I simply timed how long it took the battery to drain 5% with the screen always on at various brightness levels and while viewing an all white or all black 720p image fullscreen in QuickPic.

This is absolutely best case scenario, ignoring all other battery factors.

Best case scenarios for time, but honestly thats not what is important in these stats. Rather its the % difference between the two. The total life of a cell phone will always be different between devices/users, the % difference solely from the bright/dark difference should stay generally the same. Assuming most of the time is spent going through the UI(which is doubtful tho).
