Why does the Samsung Epic Super Amoled Screen uses some much battery life.

I was wondering why the samsung epic screen consumes so much battery life. I have my screen fully dimmed and on top of that the screen filter is around 50% and my screen still comsumes 80%-90% of my battery life. Is anybody working on any mode that will help this problem or is it because the samsung epic has a Super Amoled screen which comsume more battery life. Great phone I am just hope somebody can mode the screen consumption of the battery life. The battery is good with a custom Rom I just wish it could be even better.

You're missing the point. The fact the screen uses 80% of the battery means nothing more than that it draws more power than any other part, there isn't anything wrong with that. The screen is on so it uses power, pretty simple. Now if the radio was using 90% of the battery that would be bad.

Well that is true. I was just wondering if they cause make the battery consumption from the screen a little bit less taxing. I am grateful the the Radio is not comsumption a lot of the battery life.

Weird thing I had on my htc hero before an update was screen battery use was super high too (same levels seen here). Then after some update, it was a much more normal range (somewhere around 30-40% maybe?) consistently. I'm wondering if it's really that much of the power usage or just a bug in the reporting. Butt smoke is done blowing by me now.

The more it sits idle, the lower the percentage gets. It's a relative statistic.

Well, I guess its because the radio uses a lot less, it has to add up to 100 percent, and if you're using the display that time, then its probably what is using up the most battery

Lol I hadn't even noticed that one.
My screen takes up about 90% of the battery usage as well, but that is only since Froyo. On Froyo, the battery usage only shows Display at about 95% and Cell Standby at the other 5%. On Eclair it would show everything else that would run throughout the day like live wallpapers and whatnot. Froyo only shows Display and Cell Standby, but oh well, it doesn't mean that it's killing your phone quicker, since I upgraded to Froyo and got roms and everything installed, I get about twice the battery life.

I think you have to be NUTS to not like the Almond screen !!!

The battery life is good.

LOL!!! The joke is on me!!! I do love the display. I am just getting greed for more battery life that is all.

Yeah, as was stated above, it's just a relative statistic. The screen would naturally take up more of the total 100% allocable battery life. Makes sense, since the screen is always on when you do anything to your phone. Try restarting your phone, then play your music player for a while with the screen off. You should see that statistic change considerably.

The reason the screen takes up such a large percentage of battery life is because they made the rest of the phone so efficient!
I barely used my phone yesterday. It has been on for 1 day 17 hours since I swapped batteries and I still have a 36% charge. The screen has been on for 1 hr 59 minutes in that time, but it accounts for 71% of my battery usage. When you aren't seeing the TWS bug, everything else in your phone draws an incredibly small amount of power which makes the screen look like it is using a lot of juice.

its the price you pay for hd quality i guess

Screen filters use more voltage to apply so don't use them. And it is an app that is always running. This is an amazing screen.

Noled

Hi
Has anyone tried the NoLed app on SGS2. This is an app that simulates a LED indicator.
The display technology on AMOLED screens is suppose to be highly efficient since each pixel is individual lit. Furthermore, the black areas on the screen are where the individual pixels have been turned off. That is why the Samsung skin makes use of such a lot of black areas.
The idea behind NoLED is that when you have a missed call it will display a small number of lit pixels on the screen….again, because it is an AMOLED screen over 99.9% of the screen can be turned off….so the device should only be using a negligible amount of power.
However, I have noticed that this app consumes a lot more power than it should. If I get a notification during the night I notice that the whole of the screen is very slightly lit….you would not normally notice this….I only did because it was night time.
Furthermore, I have noticed that the graph of the battery usage declines significantly after this point.*
Anyone else got any thoughts?

Have been using it since day 1. I don't see it as a big power drainer. Whether I have notifications or not, I tend to lose 5-10% depending on how much display on time I have.

I have it on for 15 min or so. So it shouldn't drain the battery if I don't check it for a long time like during the night. CM has a great feature/tweak that lets you choose a time that the screen never goes on. Just have to wait a bit longer for it.

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.

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?

Most likely rounding bug.

Display, regardless of brightness, uses >60% of battery at all times

Regardless of what I have the brightness to, it seems display always uses the majority of my battery. For example, I recently flashed G-Lite and fully charged one night, set the display to about 30%, and left my phone idle overnight. In the morning (after about 8 hours) the battery was at 40% and display counted for 60%. The screen was definitely off. I had the phone on the stand next to my bed .
The G2s poor battery life really bugs me, especially after finding out how my GFs iPhone 4 lasts 20+ hours with heavy use.

You mean that the display accounted for 60% of the 60% power lost over night, right?
My opinion? Wipe and reflash if you can. Sounds like a weird random error. Are you running G-Lite 2.0.1, the latest version?

Correct. I am indeed running version 2.0.1.

Setting brightness won't mean much when it comes to battery life because our screens, unlike AMOLEDs drain the same amounts of power regardless of how bright or dark colors are displayed.
I'll have to agree with captainreynolds, try to reflash if you can. If that doesn't work you may have issues with the battery. Battery life is not entirely an issue with the G2, but with android itself, which tends to use more battery when compared to other mobile phone OS's.
Although, I still manage to go through a day with the battery with heavy overclocking (1,6GHz) and above-moderate usage.

Superwiped, reflashed, and still the same problem. Today I had the brightness turned down to probably 10% and after unplugging my phone lasted 5 hours. Display was 64% of the drain (40 mins on).

The g2 can have good battery life, first thing is your battery having these issues no matter what rom? Have you tried flashing a diffrent radio? Does you girlfriends iphone allow her to buy a new battery from ebay for a few bucks and install it herself with out any trouble?

Iphone heavy use for 20+ hours?? With blutooth, wifi, games, txt, videos, web browsing?? Heavy the whole time? I think not. I'm not an android fanboy or anything but that's a lil off.
As far as battery life does it do the same thing on every rom you try no matter what?

This is so annoying. I call Tmobile and they claim 4.5 hours is normal for the G2. On top of that, I can't get a replacement even though I have insurance because it isn't broken, despite the fact that the display is draining an alarming amount of power from two different batteries, regardless of brightness (yes, I have set it to 0% brightness and it only makes a few percent difference on display consumption).

so do you know what radio your on and have you tried changing to a different one?
try typing *#*#4636#*#* into the dialer change settings to gsm only. i know your problem is with display but just curious what affect this has on your battery

Are you running a custom rom? If so you could try flashing back to stock froyo then see how your battery life pans out, or u could unroot then root again.
If worse comes to worst I can recommend an extended battery for better battery life.

Could re-rooting fix it? I've been rooted since I got the phone in Dec '10

You are confusing the brightness (%) with what colors are displayed. The brightness absolutely affects battery life, as I can get up to 30% more time between charges by going from "Auto" to 35 or 40%.
What you are thinking about is the actual colors displayed, such as black versus white. On an AMOLED screen, displaying lighter colors consumes more power than than darker ones. So having dark wallpapers and interface screens can actually help with battery life. Maybe one of the reasons that the AOSP Android theming uses so much black?
With LCD type screens, the color makes no difference. The same amount of backlighting is being used regardless of whether the screen color is black or white. This is completely independent of the brightness %. So you can be displaying black, and still have the brightness at 100%.

Rooting is just giving SU permissions. Just giving yourself SU permissions again shouldn't change anything.

i too have this problem. i have read somewhere, a topic on xda, saying that its the connectors and flex cables in the phone. something about wear spots on the flex cable makes the plastic rub off and you end up seeing bare metal on the cables.
try sliding out your keyboard half way, and look at the flex cable. do you see any of the metal hanging out?

[GUIDE] Getting the best battery life

Hello,
I've been using this device for about 5 months now and the battery life for me has been great so far, but there's so much you can do when you need the juice in your battery last longer. In order to help those who want to get the best battery life out of their phone, I've compiled a list of things I do to make my phone last longer.
We'll go from the things most effective to the least and mind you, all of these can be done without rooting of using ADB etc. So let's start
'''Turn on Gray Scale'''
As we have an AMOLED screen, turning on grey scale will give you an improvement in battery life of around 25-35 %, and it's especially noticable if you use your phone in high brightness mode.
'''Dark theme'''
Dark theme obviously saves battery on our phone, there's and awesome guide on XDA guiding you to do it without rooting or using any theme engine.
'''Set brightness to 50%'''
Our eyes don't perceive brightness linearly, so 100% brightness will take around 50-70% percent more battery than 50%, but going much lower won't help either cause increasing brightness from 0-50% results in around 20-30% extra power draw.
'''Restrict background running of less used apps'''
You can restrict an app from running in the background and this setting is baked right into the App Info settings,
Go to app info and tap on battery usage, from there, restrict the app.
'''Enable data saver'''
This can be enabled via Quick Settings menu and this can drastically save battery if you're mostly on Mobile data.
'''Turn off Auto Sync'''
It is long known that doing this can save a bit of battery.
'''Enable Battery Saver'''
Pretty self explanatory.
'''Change minimum width'''
Set minimum width to anything less than 400, this leads to less information being displayed on screen which results in lower usage of GPU, and thus better battery (somewhat)
'''Reduce animation duration scale'''
This will speed up everything and improve battery life just a bit.
And that's it from me, if I remember anything else, I'll make sure to add it, and please make sure to tell me anything that works for you, I'll happily add it.

If you want to get absolutely the best battery life out of your device, you must install a custom kernel. I'm using Fenix currently.
Also, turn off printing service. This idiotic thing is turned on by default. It keeps sucking battery for no reason at all. I'm not using stock ROM now but you can find it by going to: Settings>Bluetooth & Devices (or something similar)

Can you post the link of the thread for enabling dark mode I would like to try that.

Another tip - switch to airplane mode, mobile network is one of the biggest battery consumer..
But seriously, how does greyscale mode save the battery? Instead of glowing one of the subpixels for displaying a color, all of them must be shining to provide different shades of white color. It might even use more power.
Width change and animation duration scale have some very interesting thinking behind them, it will have absolutely no impact on the battery.
Dudes, just enjoy and use the phone. Why do you want to cripple your experience just to gain extra few percents of battery per day? If you're living of the grid, there are much better phones for such a lifestyle.

There's an XDA article comparing battery saving with AMOLED on black and grey theme, you might want to check it out, or you can also watch a video by Mrwhosetheboss to see how it went for him. As for animation speed and DPI, they have the least effect on battery life as I've stated above. Kindly do some research before you start making claims.

As for animation speed and DPI, they have the least effect on battery life as I've stated above. Kindly do some research before you start making claims.

Where exactly in the article does it say that monochrome display saves power over colored one? Actually it's you who started with unique claims, so please provide some proof.
