Screen brightness and battery life.

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.

Lol, now uninstall it, set smartass governor and see how meaningless that app really is.

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

Max Screen Brightness Battery Run Down: Test Results!

Hello all,
I've been suspicious of the power draw of the screen on the GNex, and so decided to figure out how much a difference brightness made.
This is to test the difference extreme brightness settings make to battery run times. Including text, browsing or having radios on will dilute the results. I'm only interested in the efficiency of the screen and its supporting infrastructure people!
Here's my testing method.
1. Charge phone to 100% using a PCs USB charging (should give a more full charge than the wall adapters quick charge, I think, otherwise no harm done). Leave attached to USB cable
2. Switch the phone into Airplane mode.
3. Switch off Auto Brightness and turn brightness to Max
4. Restart Phone. Leave it to settle for a few mins
5. Fire up "Just Pictures" and the image "TotalWhite.jpg" (attached). No other photos in the folder where it sits.
6. Disconnect USB charging
7. Start Slide show. Record the start time.
8. Every now and then (about 45 mins to an hour and bit) I quickly pop into settings and take a sneak look at charge level - don't want to get caught out!
9. Resume Slide Show.
10. Wait until the phone switches off, which is less than 2% charge​
Now, it's not a quick process as I'm going from 100% Batt until auto shut off. So I'll be updating this post in installments. Today is the Max Daddy Full Brightness White image!
Full Brightness, White Image:
100% 00h00m
85% 00h39m
60% 01h53m
35% 03h08m
0% 05h00m​
Pretty good I think!
Battery status stated that Screen was 91% and Android System was 9%. Screen on time was the same as the run time. It never went off.
There's a heavy set of disclaimers to go with this though: The White Image isn't quite the right aspect for it to display across the full amount. Check out the image "White Full The Phone.jpg" - it's pretty close though. Just Pictures isn't so full screen that it takes over the Android buttons - Anyone know a 100% full screen picture view BTW? Between the point where it comes up with "Please connect your charger" (15%) and 6% it said that message over the White image and partly dimmed the screen - I'm at work and was in the middle of something when it happened.
Minimum Brightness, Black Image:
100% 00h00m
85% 01h26m
82% 02h05m
18% 08h54m
0% 10h47m​
Battery status stated that Screen was 85% and Android System was 16%. Yes, that's 101%, but there you go... Screen on time was within a minute of the run time.
Again, some notes on the testing: From the "connect your charger" point (i think 15%) to 8 % it had the message on the screen. Just before the end I accidently touched the screen and ended the slide show for up to 15 minutes and the screen went off. Switched it back on and it was at 2%. It then lasted something like 30 mins before auto shutdown. Black isn't Black! check out my the photo "Black Dim The Phone.jpg" - ignore the strange black specs, it was 1 seconds exposure at F1.4, with the camera facing down - think there's some crap in my camera body/lens.
Minimum Brightness, White Image:
100% 00h00m
0% 10h20m​
Again, Battery status stated that Screen was 85% and Android System was 16%. That's the same as when I ran it on Min Brightness, Black Image...
Maximum Brightness, Black Image:
100% 00h00m
0% 10h52m​
Battery status stated that Screen was 90% and Android System was 11% (again 101% also probably due to some rounding going on). Screen was on 100% of the time, Android OS was awake for 100% of the time, CPU time 23 Seconds
Overview:
Maximum Brightness White Image: 5h00m
Maximum Brightness Black Image: 10h52m
Minimum Brightness White Image: 10h20m
Minimum Brightness Black Image: 10h47m
Well, well, what's happened here? Maximum brightness with a black image scored the longest run time - unbelievable, right? Yeah pretty much: On the minimum brightness black run I did check the battery stats a few times. The black image run had a greater Android OS drain (11% vs 9%) compared to the white image. As I switch the phone off in preparation for the test it's possible I inadvertantly bump charged the phone. In addition to this, I was trusting the phone a lot more in this, the final test and didn't check the battery status near the end, so perhaps drawing a lower current happily sitting there doing nothing other than displaying a blank image the phone managed to syphon off the last dregs of power, as opposed to spending CPU time with me rummaging through the settings screens for battery stats. Let's put it all down to being in the margin of error and consider the Black images to have the same run times, despite the Android buttons blazing away on Bright (but they aren't many pixels).
Conclusion:
Back to my original concern, that the screen was abusing the battery more than necessary. I'm mostly happy with the outcome - Black bright and dim screens draw substantially less than a very bright white screen on this phone, as it should. It's surprising to see that on dimmest setting the white screen got so close to the run time of the black screens. It's producing a lot more light than either black screen. It's drawing c5% more power than the black screens, but I would expect a lot more. I'm guessing that the circuitry to run the Screen and the small amount of power used to make the "Black" OLEDs glow dark dark grey draws only a little less than the white screen.
And that's a shame. I wanted to run an app such as "Off-Clock" to have a clock on the screen like the Nokia N8 used to do, but i'm thinking this will eat the battery in 10 hours 20 minutes. Only one way to know for sure....
My initial annoyance that Black never is actually Black whilst the screen has faded. Many of you good folks have pointed out (and after more Googling) that all OLED screens have this, although the reason for it isn't clear. It's either to ease the transition from black to lit by having the LED at the threshold already, power seeping into the circuit somewhere or something else. Who knows, maybe we'd get better run times if the screen was on full brightness but used PWM or a fast strobe to show a dimmer image!
That's all folks, discuss, and remember - continue testing...

I love you for doing this. Please don't stop.

Some tidbits: The whole phone was warm, front and back. Not scary hot, but like a nice hand warmer. The screen shots were actually done after I connected the charger and restarted the phone. You'll see the graph shows it starting to charge, but all the stats are for when it was last on the battery - in the test.

Thanks for testing this.
How do you define min brightness?
The black color, do you mean #000000 hex color code?
That will last days!

Not too scientifically - I made it black in MS Paint. It's a JPG. I tried it out in portrait and landscape on full brightness and I can't see the edges of anything on the screen, so it's as black as the rest of the black in Gallery. If you have a better way, then I'd gladly take a 16x10 black image if you think it is more black.
Min brightness will be using the brightness slider in settings. I haven't rooted the phone so don't see any way to get it lower. I tried the app "Dimmer" but it's the same brightness as far as I can tell as min setting. Also I figured the min setting was relevant to more users than something they can't easily get to (or probably see on screen!).
Do you have any suggestions? I want to root, but my home PC can't see my GNex. It's being a pig about it and I haven't got Broadband ATM... Hope to root as soon as I can.

Just a quick input. If you just show a picture for 5h how does the cpu perfom in this time? Isn't it really bored?
In addition if you switch it to air plane mode it doesn't use any power for transmitting a signal. I know this point is really tricky due to the fact that not everybody receives the same signal strength.
Isn't there a more realistic way to test it? Like a combination of stability test and the white picture?
Or a slide show with specific pictures, for example a picture with lots of green, one with a lot of red, one with blue, one with white and one with black?
I really like the idea but if we could create something like a standard which tries to simulate real usage that would be great for future testings.
So that we could say something like:
Galaxy Nexus with Vanilla Android -> 5h with XDA battery benchmark
Galaxy Nexus with CyanogenMod 9 -> 5.3h with XDA battery benchmark
We could compare different settings and see how good they perform based on a "standardized" procedure.
Hmm is this probably a bit too much?

I like the idea of a standardized battery procedure for XDA.
Only thing is, i feel like just web browsing would give a better idea, mostly white website sites and it uses data and CPU/GPU still to give real world usage results.

Hi Nebucatnetzer, I get what you're going for and think it would be a great test. My original goal was just to see how much of a drain the screen was. I used it on Airplane mode as I do not want to have any other drains diluting the result. As you say, signal strength changes, and so this becomes an uncontrollable variable. I'm only showing a white image as it's the most uniform full power test of the screen I can think of. As the display is RGBG, maybe a greenish white would draw more, but I can live without that - web pages are predominantly Plain White and Text in ICS is white.
I actually think that 9%/10% drain for Android OS may be a bit high for 5 hours. I think Just Pictures may be the cause for it as it does every minute change the image in a slide show... to itself...

It was one of the things which annoyed me the most here. Everyone says he has the ultimate tweak to save juice but you never really could measure it.
We probably have to skip the data part due to asimilar signal strengths.
And it would be really cool if we could find something which works for every phone.

Hi! I'm not trying to do a real world test as such. I'm trying to find out how much of an impact a white screen has compared to a black screen. I have a suspicion that the Black screen will draw more than it should do. I've been using my phone on Auto Brightness and at night, min brightness and have found the screen is caning the battery. There's more to the screen than the AMOLED - there's also a MIPI Framebuffer controller, plus whatever interfaces that has to the rest of the phone.
I'm aware that ICS and the other internals of this phone seem quite efficient, so any savings I can make on the screen (which really does suck the juice) should translate into big run time gains... Surely...Right?
If it turns out that there's very little different in battery life between a Black screen and a white screen, then I'll crank up the brightness to revel in its retina destroying beauty. If there is a difference, then i'll stick with my black homescreen background....

The black screen shouldn't draw any power virtually as long as its truly black. SAMOLED functions where black doesn't turn the pixel on so no energy is used. I think the black test has been done by someone, you can probably google it.

We we aren't criticizing you specific we just hijacked the thread a bit sorry for that .

would be good if someone could make a benchmarking program which pumps out signals in a set pattern on all devices at set frequencies and at a few different power levels. It would't need to wait for a response from any cells or WiFi routers, just talk to itself and only itself. Maybe this would need too low level access to work, below root.
Then you'd have your predictable Radio part of the test. If it's even possible.

Well, I hope a black screen will draw considerably less. We shall see. Or it will be a revelation... Or everyone will get to witness me finding out that my phone is defective. Hahaha... oh...god I hope not...
I may run the black test overnight. It should last the night. If it doesn't I can always hook it up and check the last "On Battery" status as I did earlier. Then I can run two tests tomorrow!

This sounds more than difficult. Not a clue how one could do this.
As soon as I have my device I'll probably start a thread where we can think about a standardized (what a stupid word) battery test.
Curios how your second test goes.

Instead of the black screen test, amoled screen, you could do a white background with black text. This would give better overall real world stats.
Text generator http://www.lipsum.com/feed/html

Second test - black on lowest brightness - is underway.
Some bad news, which you may already know about: Black isn't black. It's very dark, but the phone isnt switching all the pixels off. I took a photo with my SLR in the dark but can't upload at the moment, will upload tomorrow.
Just took a sneaky look at the stats.
85% 01h26
The draw is 85% screen and 16% Android OS. Yeah, I know they don't add up, but that's what it says.
So far, the draw is higher than I expected for lowest settings with a black image. Odd. The phone isn't warm though, like when the screen was showing a white, max brightness image. It's cold.
Sure hope it doesn't start moaning about running flat whilst i'm asleep...

Last check before I go to sleep: 82% 02h05
Same split of 85% screen and 16% Android OS. Who says percentages have to add up to 100?

[Q] Screen gets hot?

The hottest part of device is upper third of a screen, is it normal? I read a lot of complaints about overheating but I didn't see anything about hot screen. Also, in attachment is what CpuTemp shows for apps. Is it ok? Temperature goes up to 140 F with 4G browsing only. Thanks

Turn the screen brightness down and see if that helps... It did for me, about 60-70% brightness made a difference

I never set brightness higher than 50%, and screen gets hot even on 20%. It seems like heat comes from CPU but I'm not sure if it's normal that the screen is the hottest part

Yes, the cpu is facing screen, so a lot of heat is transferred to it.

Im outside alot and at 100% brightness its like lava in my hands so i figured 60 would be sufficient... I guess its typically 50 or lower when indoors now that I checked. Are you on stock firmware? You may try scaling back your CPU to 1958mhz max and 300min with ondemand governor...

It doesn't use much battery compared to Adaptive Brightness off unless you keep your screen at something low like 10% or less the whole time.

I've always, even with previous phones, used manual brightness. Partly because I am usually happy with brightness to be kept at, for this device, at 15% and if I need to adjust Ill use Brightness Control. I also feel that battery life must surely be better as the sensor isn't constantly being used to gauge how bright the screen should be and lastly always found autobrightness to increase/decrease the screen brightness randomly, e.g. Say in my living room and it'll just increase/decrease slightly.
So ultimately I'm very happy just to manually adjust

Mine is set to.20% with auto brightness enabled. At most times it hovers very close to 20%. I guess if i disabled auto brightness i will get better battery life. At the moment i average 7 hrs SOT.

Question Charging light never goes green

Hi. I contacted Asus about an oversight in their software. The charging light only goes green at 81% so if you set the charging limit at 80% the light will never turn green.
If you'd like this fixed please leave a comment.
Here is a link to a zentalk post if you'd like to make some noise there.
https://zentalk.asus.com/t5/rog-phone-6/charging-light-never-turns-green/td-p/365409

"Fixed"? Depends on how you interpret the light indicatior. ASUS gauges relative to total battery which I bet a lot of users are happy with and find logical. It btw also has the advantage that if you temporary disabled your charge limit to juice up to 100% without protection but forgot to switch back, it's a nice reminder that you may want to switch the limit back on again for better battery life.
What they could do is making both options selectable. That way both groups of users are happy.

If it turns green at all levels over 80%, then it is so by design. They are using the 'greater than' logic instead of 'greater than or equal to'.
What happens if you set the limit to 79%? Does it then turn green at 80%?
And what difference does it make if you just stop charging at 81% instead of 80%? Why bother with such insignificant detail?

Yes because I have the charging limit set to 80%. So essentially I don't get the green light at all.

It can only be set to 80% 90% and 100%. Also the battery would never reach 80% if the limit is 79%.
If the phone knows it has reached the charging limit it should display a green light.

So you get green light if you set the limit to 90% or 100%, but not when you set to 80%. Correct?

Pretty sure it's an oversight. Mode 2 does what you mentioned. Only showing green at 100%.
Mode 1 displays green at 81%.

It is a very minor change required at their end. Just set it to 90% and forget about the theory of charging till 80%. There is very insignificant benefits from that practice. Different OEMs seem to have different thresholds for this theory. Samsung gives an option at 85%.
I always charge my phones to 100% every single time. My phone batteries have never given me problems in 4+ years.

The idea is that when the battery degrades I'll raise the limit and get a bit extra battery. Thats that ev do

You will hardly see any benefits of sticking to a practice like this on your phone which you would most likely replace in about 4 years time.

Would have been nice on my last phone tbh
For now I'm using gsam to send out a notification

Mode 1 and Mode 2 do exactly as expected and as described.
It's just a matter of how you perceive the charging range. They use the actual 0-100% of the entire bat capacity to reference the indicator off. You would like a relative scale based on your selected max charge - which also has merits, but they haven't gone for that or built that in as an option. Adding it as an additional mode could probably do the trick. Either way, a tiny detail...

When you have one feature make another unusable it's not a tiny detail I'd say.
If mode 1 displayed green 1%lower it would be fine
