Brightness setting - T-Mobile Samsung Galaxy S II SGH-T989

just curious what is everyone brightness setting and how is your battery life

i like mine at 30%
battery life good, as you can see in the big battery life topic

30% seems to perfect for me too
just enough to hide the lines, and gets around 15 hours with a ton of use.

you forgot to mention at that setting it makes the images more vivid
while you can save more power by having it at 20% or even 15%
but then the images looks like any other regular SLCD display, or even pale if you set it lower than that

I love in Arizona where the sun can be very bright so most of the time i'm at near full brightness

55% brightness is perfect for me. I found it's the correct setting if you use the stock browser at manual brightness also. Meaning if you turn off auto brightness in the stock browser you can't match the brightness setting with the screen. If you ever tried it you can get exactly 50% on the screen, but the browser only goes slightly below or slightly above 50%. It's a minor detail, but it urked me every time I opened the browser, and the brightness changed.
Anyway, at 55% brightness I get about 18 hours of battery life, and within that my "screen on" time is anywhere from 3 and half, to 4 and a half hours. Depending on what I'm doing. Basic browsing last longer. Games shorter.

I always keep mine at 100% to really use the Super AMOLED screen to its greatest capacity. My battery life varies, with consistent usage, I get a good 4 - 6 hours. I'm currently using the Juggernaut ROM

In a bright room I just leave brightness off. It seems sufficient enough as it is. Outside in sunlight I use 30%.

[Q] Auto-brightness

Anyone else notice that the screen brightness is ALWAYS at 100% when auto-brightness is on? The only thing that changes is the keyboard backlight. It will either be on or off, depending on the lighting I'm in. The screen, on the other hand, always seems to be at 100%.
That's not true for mine. Granted, it doesn't change much, but it is definitely not full brightness most of the time unless I'm in bright sunlight. I'd be happy if I could set the range. It's usually brighter than I need it to be.
Mine is also always at 100%. I just use a widget to toggle 2%, 50%, and 100% without Auto as a setting. The screen is actually efficient enough that you I've gone all day at 100% without really draining my battery too much. Right now my phone has been unplugged for 14 hours and the battery is at 55%.
Yea mine is like that. I see no difference between auto and high. It doesn't even go down at all.

display battery usage?

the diplay on the screen is what takes the battery up the most according to the battery usage setting. its on the lowest brightness and still always gets around 70-90% battery usage...
is this a bug? or can i lower how much display uses for battery life purposes?
im currently running regenecide 1.1.1 with the stock ef02 pastel blue for ec05 theme if that means anything
it says displays been on for over 3 hours and been last unplugged for 13 hrs and 14 mins with 30% left.
There is an app called screen filter which will help you lower your brightness. Also try using a dark theme. My port of erebos is pretty blacked out, even the dialogs.. I try to have as much black background with light text as I can, which helps with our samoled screens. And of course screen off time should be at its lowest.
cd's or tapes?

[Q] Battery question - How much 'Display time' do you get?

Hey guys. First thread.
On average, under battery use, my (AMOLED) display uses around 75% of my battery. I can usually get around 3 hours of display time before my battery dies.
I'm running Cyanogenmod 7.0.3, I've got SetCPU on 245min 614max, ONDEMAND.
The kernel is untouched, but I will consider changing it soon once I find one thats good with battery life.
So then, how much display time do you all get? As this seems to be the main battery eater. This basically reflects on how long you've used the phone too.
By the way, brightness levels fluctuate between 75% and 100%. So yeah its always bright too.
Thanks in advance for the posts. It's appreciated
I've never found Battery Use to be accurate on Gingerbread roms for some reason. It always seems to take a high percentage (around 50%?) despite the phone being used maybe 10 minutes a day and lasting without a charge for up for 2 days 12 hours.
Froyo (when I had Sense) didn't have Display taking up a high percentage and looked more accurate of how the battery was being used.

[Q] Battery Life Issue

I am having battery drainage due to the display (unlike most people who are having battery issues because of the android system). I've tried dimming down the brightness and putting the screen timeout to the lowest possible but the display still sucks up most of my battery. Can anyone help me with this ?
I think that would be normal. It's a 4.5 inch touch screen; it takes a lot of juice to be so pretty ...
Under settings - about phone - battery usage - display, what is the time on vs. % of battery usage?
I've been off the charger for 30 minutes and display use is at 76% since I've been browsing news and xda non stop.
If your screen on time is low compared to it's battery usage, it's a different story. Sounds like you've tried the usual fixes.
Well I've been off the charger since 12 last night so it would be 12 hours. But the thing is that the display usage says 51% and the actual time on for display was only 2 hours.
and also my battery drains 1% about every 30 minutes with the screen off.
2 hours of screen on time sucking 51% of the battery sounds normal to me, even across other Android phones on GB. Touch screens use lots of power.
Maybe someone else can chime in with something I'm not getting, but it seems normal to me.
This is a screenshot of my E4GT after 33 hours off the charger with normal usage. I don't play games, but I do text a lot and had a few calls as well. As you can see, the screen was on 20% of the 33 hours, meaning 6.6 hours etc etc and I still had 9% battery life at that point.
I am loving my phone!
Doesn't that 20% mean that the display used 20% of the battery power, not that it was on for 20% of the time? If you select the Display, it actually shows you how long it's been on.
I just feel like my battery should last longer than it does. I used to own the moment and that would last me three days with moderate use. ButI guess that this phone is more powerful it would make sense not to last three days. If only that would happen haha

Screen-on makes the phone hot and sucks battery quickly on my LTE Gnex

I always notice my Galaxy Nexus gets quite warm when the screen is on. I was unsure whether this was due to CPU/data usage or something else. Then I noticed that if I leave the screen on while charging, the phone is warm near the top. (Even after fully charged overnight.) With screen off, a fully charged phone is totally cool.
Overall the batter life seems quite short on this phone. Even with just light usage like reading articles, the batter seems to drain quite quickly.... and I have a feeling it is the screen that is doing this.
So I did a very unscientific test: 10 Minutes screen timeout, both set to auto brightness indoors, screens look about the same brightness level.
Galaxy Nexus LTE: Started 68% and ended up at 63% .. had been 63% for a little while so I bet it was about to tick over to 62%. Top of the phone and screen was quite warm. That ends up being 30% battery per hour just to have the screen on and at low-moderate brightness.
Droid X: Started at 94% and just ticked over to 93% right before turning off. Phone totally cold to the touch. Comes out to about 6% per hour.​
On my Droid X, I could sometimes get 4 hours of screen-on time on one battery charge -- this would usually happen with light usage like just reading wikipedia articles, etc. Not data intensive stuff. I haven't had the Galaxy Nexus long, but it seems getting over 2 hours is tough. (Both phone I keep on auto-brightness, and it actually seems like Droid X keeps the screen brighter in general.) This is with the same usage patterns and I have the same software configured on both .. syncing the same way, etc. (Touchdown Email and full Google syncing, plus weather app and a few other things.)
In airplane mode on the Droid X, like on an airplane, I used to be able to watch videos for like 5 hours using MX Player easily and have batter to spare. (Hardware acceleration.)
At the battery drain I'm seeing on the Galaxy Nexus, a full charge battery would be dead in about 3h 20m just by having the screen on and the phone totally idle! That can't be right. The screen brightness is pretty low on auto brightness and that's just abysmal.
Anyone else seeing this on their Galaxy Nexus?
Just another test -- all phones on airplane mode. (All radios off) Brightness matched as closely as possible. (Fascinate was slightly brighter than other two but it has a smaller 4" AMOLED screen so I figured it was ok.) All phones on battery status screen.
Droid X Started at 89% ended at 88%. Phone totally cold.
Galaxy Nexus SCH-i515 Started at 56% ended at 52%. Phone warm at top.
Samsung Fascinate SCH-i500 - Started at 93% ended at 92%. Phone totally cold.​
Fascinate is running ICS 4.0.1 with a gingerbread kernel. Forgot which build of ICS.
Anyway, this can't be right -- only 24% per hour at this rate with all radios off for Galaxy Nexus but even with that, just sitting there idle at the battery status screen would kill the battery in a little over 4 hours.
And I had the Galaxy Nexus on auto brightness but the when I unchecked it, the equivalent manual brightness was about 10% from the left on the slider. (Very dim as I'm inside my apartment right now.)
I will try again with the slider at max brightness....
*SIGH*
OK, WTF! I set my Galaxy Nexus to maximum brightness and did the test again.
Start 52% and after 10 minutes 49%. ​I don't understand how the usage is less with the screen at maximum brightness! Phone is only very slightly warm at the top too. Much cooler than previous tests. I wonder if this is the auto-brightness feature causing excessive CPU cycles?
Will try again with brightness set to 10% (similar to auto brightness) but with auto brightness unchecked....
Start 49%, end 47%. Only 2% drop in 10 minutes. Phone feels cold at the top.​
One more try with auto brightness enabled again:
Start 47%, end 45%. Phone feels cold at top now. ​
I don't know what is going on... anyone else seeing similar things?
(PS I have LTE disabled since I get a very weak signal in my apartment as it is and I didn't need it hunting back and forth.)
I can kill the phone in about 2 1/2 hours at full brightness as well.
