GNex Screen Power Consumption Study

[jkc120]

These are all real-world usage situations. Not all black, not all white, not all of any one color. This is average power usage per minute throughout the day using the same apps every day for roughly the same amount of time. I know that when I use web browsing more one day the power usage will be higher that day and I expect it because web pages are mostly white. I do imagine if you siet it to all-white, the difference would be great, but that wasn't my purpose in the study.

Ah sorry, I missed your info on the test procedure. So normal usage each day, but do you have a lot of inverted apps installed? Just curious how much I might improve if I were to use the inverted gapps. Mostly I use the built in messenger and gmail, so those are the two I'd want inverted. But I don't think there's a 4.0.4 inverted messenger yet nor a gmail from gapps 3/17 that's inverted.

I figured I would step in here and relate a brief exchange svt and I had about this issue in a very unrelated thread.

After seeing how much of a differenc it makes having white or black backgrounds in apps, I'm now searching for alternate apps that use black backgrounds. Will consider re-theming others that do not have suitable alternatives.

I noticed this a long time ago and switched to a dark background. Also, I have tapatalk set to the dark display style. And it really is the white that kills it, not so much with colors.

I play a soduku game with a white background that crushes my battery relative to something like angry birds.

Yep, I can play the Sims or Angry Birds and not affect the battery a ton, but the same amount of facebook or web browsing kills it if I have any brightness whatsoever. Really toning down the screen brightness helps a little, but white still kills it.

Exactly what pupkact quoted. After seeing the difference I applied the dark handcent theme, downloaded Plume for twitter and applied dark theme, applied a dark wallpaper, and will be looking for other dark options.

I CANNOT overstate this...white screens KILL the battery, even on dim. I need to find a way to make the screen in the browser black while web pages load.
