Help Screen using 70-80% of battery?

Everytime I check my battery stats the screen is using between 70-80% of the battery, even when I have all the settings at the very minimum possible (eg. 0% brightness, 15 second screen time out, etc.) Anyone know why this could be?
 
Hello francisfoglian and welcome to AF. :)

Have you hit the update button? It should be taking up way less battery than that if you have the settings down that low. Usually if I do that it'll update and tell me what amount of battery is really being used. Hope this helps. :)
 
could you get us a screen shot of this?
also, tap the screen area to give you more details about how long the screen's been on and such. and a screen shot of that would be nice too.

I will say that most likely it's because you unplugged it from your charger recently and that's what it's displaying.
remember that the screen drain at 70-80% means of the already drained power.
so if you had your battery at 80%, the 70-80% on screen means 70-80% of the 20% battery used has been on your screen.
 
I dunno how I'd get the screen shot onto my Mac since the stupid thing won't connect but my phones been on 14h 18m 25s since 100% charge, on and off the charger, 13h 41m 3s just on battery and the screen is 3h 9m 53s of this time. It's current settings are Auto Brightness, 1m screen time-out and on Dynamic, but this is only 6% more than when I've had it on 0% Brightness, 15 seconds screen time-out and the Standard setting. Does that help?
 
It's probably displaying what percentage of battery it has used up. As GoldenDiamond said, if yo have 80% battery and 20% on screen then that is how much battery your screen has used.
 
So my phone is on 6% left right now, so of the 94% that has been used all ready the screen made up 86% of that? That would explain why it doesn't change when I play with the settings. I still don't understand why it's so high though I use Facebook, Twitter, Instagram and am messaging pretty much flat out yet the screen seems to be the main reason I lose battery :/
 
If the screen is on constantly, it will be a massive %. Its the biggest power draw on your device by far.

We'd really need to see a screenshot of the main battery stats page and teh screen on page (both necessary for us) to see whats going on.

Ensure Motion is turned on in settings and within there "Swipe palm to take screen capture" Then you swipe the side of your hand from left to right over the screen to take a screen shot.

It has been my experience that no matter what you have your screen set at, it will almost always be the main user of battery unless you're constantly streaming from the internet or something. It's all relative anyway. My screen is a HUGE percentage of my battery usage but it doesn't matter because I get MANY hours of usage with my extended battery. I happen to keep my screen on 100% brightness because that's what I need in order to see best. I expect it to be the biggest battery hog but it doesn't really matter to me since my battery lasts as long as I need it to.
 
It's a lot easier to screen shot just holding down the Power and Home buttons simultaneously, I'll recharge my batter over night with the phone turned off and take a screen shot every few hours and then post them up tomorrow :)

I really struggle with that method ;)

Indeed. Also the figures Android uses to calculate the Screen usage are estimations only. So the graph can show a lot more than it actually is. Its very amateur.
 
Ok so this is when I turned the phone on after taking off the charger at 100%

Is that more helpful?
 
Unfortunately not really. We really need you to press the Screen row and shot that screen too, otherwise it doesn't tell us anything about context
 
Hmm. That's quite a lot of screen on. Yeah I wouldn't say that is necessarily bad. I would expect it to be a bit lower at 0% Brightness though but not sure what can be done about that.
 
I'm one of those people who's on their phone pretty much flat out so I don't expect it to last more than 12 hours I just thought surely the screen can't be using that much off my battery compared to all the other things I'm doing.
 
Yeah it can be. everything is optimised to use as little power as possible. Its just theres not much that can be optimised when it comes to screen.
 
Just keep an eye on it is all I can suggest at this point. Nothing seems excessively wrong presently.
 
Yea, the other things you described basically use no power themselves. Your power is really going to the screen.

Try loading up a large game from the play store ( right now theres a free one that looks like itd hit your CPU pretty good, "Death Dome" ) and let that run for awhile. You should see that game and probably android itself jump up higher. If it does, then everything is normal, it's just that your regular usage has nothing drawing much power besides your screen.
