I've always been told to keep it on 25-30%, as opposed to automatic. Supposedly auto uses more battery, but i've never really tested it, to see how drastic the difference is. I'm good with it at 25-30% anyhow, so I just leave it there all the time.
I can't stand auto. I always just set it at the lowest acceptable brightness level. At night I have it pretty much all the way down, during the day it's up a little higher.
I figure it would be better to just stick with low light. It's amazing how things are when you turn up the brightness. Until you look at how much battery you used.

As long as you cab see the content in your screen it should be fine, I just to control my brightness but I got tired of it and get the almost the same result in battery life without wasting my time doing it myself

I have been searching for 20 mins and can't find an answer (first time using the app so may have missed something).
I was wondering if anyone had any data on brightness % and power usage. People seem to go to great lenghts to change the brightness levels but I remember something on last years Google dev. con. videos on YouTube that said it didn't make as much difference as originally thought. (i can't find the video either lol. Bad search day here).

The biggest improvement in battery life (IMO) comes from setcpu. I also keep my screen at 40% which I suppose helps some. I've got a Mugen extended life battery and setcpu set at around 537 max (on demand) with the screen off. I get 2 days out of my battery... And I use my phone a lot.

The bad thing is that on Sense roms, I have yet to see brightness going lower than 30%, even in pitch dark. Aosp does far better job as long as brightness is concerned. Setting it at low value is not an option for me either as it renders your phone unusable in direct sunlight.

Every rom has it listed under its changelog, usually it is smartass for sense roms. It isn't by accident either, some have reported lag waking the phone up. I haven't across almost all roms available, and even if I did I'd still prefer 20% less performance over 20% less battery life.

Why dont u test it wiht currentWidget or so? Okay, i did it:
0% -> 125mA
25% -> 150mA
100%-> 280mA
So what do we learn? Brightness and/or Screen has a big impact and probalby most people here trying kernel tweaks and whatever to improve the battery dont understand math.

Agree. Just check the battery usage, you will get the idea.
On mine, display usually uses 40% - 60%, with data always on.
Apologies for the late reply. lost internet connection for a week then forgot I posted it
Thanks for the replies guys. I eventually found the video, took ages lol
(youtube.com/watch?v=OUemfrKe65c).
According to what they say in this the screen actually doesn't account for that much of the total battery usage (mainly due to the screen being off most of the day) overall given everything else using battery.
i.e. coming up with a way to keep the device asleep for longer when turned off would completely out strip any adjustment to the screen brightness in terms of battery life.
So things like lower cpu when in standby can be really good but only when not getting data transfer (as this needs to be done very quickly as its expensive).
As adjusting screen brightness is easy to do I think that is why so much time is spent on this. In reality though it seems like it is only going to give a limited battery life increase.
But if you put low cpu, the cpu needs more time at low to do the same that a fast cpu, thats why the setcpu apps its a bit crap. I think that set low the brightness of the screen save more battery than putting the set cpu really low... (just my two cents)
I leave the brightness on my phone to around 30% for better battery, and i can see it ok in the daytime. I have recently had it up at 100% and noticed how quick my battery goes dead.

Very true.
I guess ideally you want the CPU low when its not doing anything and high when doing data transfers etc (to speed up the high current draw activities).
I guess a good app would be one that puts the phone in airplane mode for 90% of the time when inactive. Only coming out once every so often to check for text/data etc. I can see that giving better returns than anything else. from what was said in the video a phone in standby doing nothing would apparently last nine days (as apposed to one normally). Given this data I guess its possible to double the battery life with this kind of app.
I may have to have a go at writing one

I agree that turning the brightness down makes sense and saves battery. It just seems a disproportionate amount of time people spend over brightness vs better ways of extending battery life.
I guess the rewards also depend on the amount of time you use the phone as the more you use it, the better reward from the screen and the less from the standby solutions
So I've always used my phones with automatic brightness, but it seemed like this one would always be really low. The only time I would see the brightness change at all was when I'd take my phone out in the day when it was sunny. So I decided to switch it to full brightness on all the time and haven't really noticed a big difference in battery life. Plus with such a great display it looks so much better with the full brightness on. Any of you tried this and notice a big battery drain??

Im the opposite of you. If i have my brightness pass mid, my battery will be drained in no time. So i am forced to use low. I cant even use Auto Adjust, because that will also use a lot of battery. Mid and higher, my battery drainage will be around 59%-65%
For me full brightness really kills my battery. I I used to do full brightness but after going on my quest to improve my battery life I ended up sticking with ~50% brightness

The display is (generally) the biggest drain on your battery, so adjusting the brightness level accordingly definitely has an effect one way or the other. If I'm not in direct sunlight I leave my brightness very low, usually around ~15-20%
One of the biggest battery savers I found was a new watch my wife bought me. No more turning the display on/off throughout the day just to see what time it is
After I changed it to minimum setting, my GNex survive from morning until the end of work without charging at all and it's still have 56% battery (normal use: up to 50MB data download, messaging, one or two calls, 9 hours or more screen time).
Is it normal that brightness is the most heavy resource eating the battery?
Um... yes.

9 hours and still 50%+ is also a blatant lie unless you have a 812948712mAh battery ducttaped to the phone...
I can get 9 hours of screen time no prob! (if my phone is plugged in the whole time) :cyclops:
Just look at your battery life report after 1 day of usage. Its blatantly clear that the screen is the biggest battery drain on the device.
Also calling BS on 9 hours of screen on time.
Yeah I think he meant... 9 hours overall not screen on time. That would only be possible on 0% brightness on a black screen.

The screen is huge for a phone. It uses battery to light up.

Dude that's first-day stuff. Brighter the screen = more power being used. Avoid auto brightness too, all that constant adjusting of brightness is no good for your batt either. Just toggle it as needed :thumbup:

Or if you have one of those roms where you can slide your finger across to manually adjust the brightness when needed, it helps save a little on battery life. But the days when you could just check the auto brightness box and be all good (ics) are no more now that jb is here. Even with that checked, you still have a screen that's bright as heck and devouring your battery.

I can't relate to any of that. Auto-brightness is fine, always has been. And there is no difference in screen brightness from ics to jb.
I read almost everywhere that auto brightness is not good for battery but never tested it.
May have to do with the sensor. I've never liked auto brightness, personally. I usually set mine at like 30% during the day and 0% before I go to bed.
Auto is too dim for me so i set it around 79%. Higher brightness hurts my eyes but maybe I just need to get used to it?

I turned off auto and set the brightness to 100%. I love a bright screen. So far 17 hours on battery, 2 hours screen time, and still at 50%. Good enough for me.

Turn off the lights.
I keep it always on 100%. Only when I need to save the battery I lower it.
Would love to get more input.
I simply use auto brightness. Bright screens look better but they strain my eyes too much.
I keep it at 50% and thats super bright for me... Keeping it 100 sounds insane
Sent from my LG-D851 using Tapatalk
Apparently I'm in the minority so far. I hate screens that are too bright for the setting they're in. I keep mine at absolute minimum (0%?) unless an increase in ambient light makes it hard to see. Then I increase it as little as possible until it's at similar visibility as it was before the ambient light increase.
i keep mine at 50% also, i could see doing 60% if i really needed it but anything over that would be overkill IMO.
I use auto
auto 100%
I use Lux app. Check the PlayStore and see if it might work for you.
You guys no you can adjust the contrast.
Sent from my: T- Mobile LG G3
80% most of the time. I adjust when/if I need to.
Usually <50% indoors and >70% outdoors. The best way to make it learn what you like is to use LUX app.
Do you guys leave always on display on? Should i leave it off the save battery?
I turned mine off. Kinda pointless IMO.
I don't think it is a substantial hit. It turns off when in a pocket.

Only you can decide what amount of screen on time you want and what gets sacrifices to get there. I'm easily getting through the day without turning it off and I like having the information. If you like it and you're getting the battery life you want by all means leave it running. Shiny new toys would just be new toys without the shiny.
I have it on from 6am to 10pm then off while I sleep. I find it useful at times during the day.

I have it on, not a great batt drain, it loolks awesome, thknk about this, You want a great device, full of functions, real unique charateristics, , so? why all rhe compñaints about battery life? if so concened boit batt life, go get a chimese unbranded set
I turned mine off the day I got it. Reason for that since it uses AMOLED screen which means over time you'll get burn in (actually it's really burn out) which can't be fixed. From what I understand it moves slightly to prevent that. Still why chance it?
I have mine on all the time, but honestly I find it can be distracting often. I have gotten to the point of NOT wanting my phone to be bothering me 24/7, and have found actually turning it off for days at a time is a good thing. But that's kind of a different point... fact is, the AOD is something that attracts the eye and attention, and I find myself turning my phone face down or away from me so that I am not constantly looking at the AOD. Not the phone's or AOD fault, just how this works. It is nice to have the option of AOD and I don't think it effects the battery life much.
Mine is only off at night because I like to sleep in the dark. All day long it's super handy to be able to glance down at the phone to see the time and other info, plus it looks cool.
I keep it on 24/7. The battery consumption is too minimal for me to loose the information it provides if I were to disable it. As long as my device can last two days on a single charge I'm happy.
under what I would class reasonable use I'm getting from 6am till midnight and still having 40%+ of battery so can't really complain as it's not running the battery down enough to the point where I would want to save battery.
Love this feature and never turn it off. Makes a great night clock.

Battery consumption is definitely minimal. Two great things I learned from this thread: you can change the color, and you can set on/off times. Sweet.

It can auto-off AOD when in the pocket or facing down.
