Hi,
My girlfriend has recently bought a Galaxy S. It has not been rooted or flashed. She's having a problem where the display is using 70% of the battery, even with the brightless set low, as shown under Settings -> About Phone -> Battery
Unplugged for 7h 15m 28s
Display - 70%
Cell standby - 10%
Phone idle - 5%
Android System - 5%
Android Core Apps - 3%
Android OS - 3%
Internet - 2%
Has anyone heard of this before?
What can we do to fix it?
Thanks
Scott

Likewise, the display is draining the most battery comparatively to other things. (I'm using the lowest settings)
Im not speaking from research (how other superphones behave), but wild guess - it is normal for all touch screens, especially bigger ones.
Touch or not - it doesn't matter.
Screen technology and size matters.
See 4" has around 4 times the area of 2" display.
How long was the display active for ? This is normal if you have it turned on a lot at high brightness settings.
i'm not surprised even if the 70% is true, because my HTC Athena is a power hog when i keep the screen on for a long time, the juice que sucked up in a couple of hours of use.
the SGS i9000 is having a better run for the power.
at least i can play 3D games (ASPHAL5) in it without worrying about running out of battery like with my old HTC Athena

See, you are kind of reading this information wrong, IMO. Yes, the display usese 60+% of power, regardless of brightness settings, if you have the display on. Here's the simple math:
Standby time (no sync, no 3G, basically, literally just standing by, screen off doing nothing: 24-25 days
screen on time: 4-7 hours.
You can see that the screen sucks SOOOO much more power than just about everything else your gf had going on in her usage, there wasn't a high usage scenario other than the screen. However, if you use something like GPS the stats will "look better" but you'll have less battery because it'll go from screen to 40% and GPS to 30% but your battery would be nearly dead.
Also, if she just went to sleep then Cell standby and Cell idle jump by 1-5% each and then you have "better looking" statistics.
This essentially means, if you use the phone with the display a large percentage of the time that the phone is unplugged, expect these percentages. I unplug my phone at night, when I wake up my display percentage is 0% (not necessarily better than 70%, because it's usage dependent), then I go to work, so I might run unplugged for 20 hours, use 8% of my battery with my display reading at 20% of the power used. Then, I'll go home and play with it and it's upto 40%, the moral is that it's good to know how much your battery is used on various tasks, but anywhere from 20-70% is normal depending on how much you actually have the display on while it's unplugged.
70% sounded right. There was a youtube VDO that dissemble galaxy s awhile back that really give a good perspective.
The CPU, GPU, GPS, memories etc etc almost fit on your thumb. They are so miniturised and so small. The rest are chassis, batteries and screens taking up almost all the space.
So it is no surprise that the screen should be what guzzling down all the batteries.
didnt know it uses that much...
She's having a problem where the display is using 70% of the battery. [...] What can we do to fix it?

The easiest way to fix this is by installing & running multiple applications that consume a lot of battery power. This should lower the percentage of battery power that the display consumes significantly.
(Only posting this because you already got more helpful answers in this thread)

Thanks, but that's the thing, I have a Desire and if used similarly (with brightness set highest) mine shows:
Android System 31%
Cell standby 21%
Wi-Fi 21%
Phone idle 16%
Display 11%
I thought the Galaxy S's screen is supposed to be more power efficient than the Desires so that's why it doesn't make sense to me. Again today her battery use shows:
Display 61%
Cell standby 17%
Phone idle 10%
Android OS 6%
Android System 3%
Internet 2%
So I think either my phone (Desire) is reporting the battery use wrong, her phone (Galaxy S) is reporting it wrong or the display is using more than it should? Now I had a similar battery % when I flashed a few 2.2 roms onto my phone, but people were saying that was because the drivers weren't correct. (I haven't flashed 2.2 recently)
Cheers

Hello,
Same happened to me, but I used live wallpaper. When I turned to the simple wallpaper the usage from 75% dropped to 50% -keeping all my other activities constant.
Chryssa
I don't think that the info displayed by android is very accurate.
I get about 55% too though.
Sent from my GT-I9000 using XDA App
Just press on the display-bit, and you can see how many hours/minutes it's been on.
19 hours since unplugged:
Android OS: 36%
Cell Standby: 25%
Phone Idle: 18%
Display: 14%
Wi-fi: 3%
Android System: 2%
Those 14% is 31minutes continious use...
31 minutes of Display time is nothing over 19 hours, hence the low percentage. Mine shows approx. 50% usage when it's been used say almost 2 hours and phone awake time 14 hours.
For the OP, if you don't tell us how long the display has been switched on ... all the answer will be just guessing
As everybody says, the display is always the bigger battery consumer unless you use your phone as a mp3 player or just a phone to receive call.
If you go on the web, play games, read mails, use maps ... the display will always be the biggest ( maybe the gps can go higher ... )
On my side I have 65% of battery left after 7h unplugged
50% of display for 1h4mn
21% of android OS
13% of cell standby
8% of phone idle
It's all down to the comparatively slow advancement of battery technology.
Screens are getting bigger, higher resolution and more power-hungry. Just the same as processors and GPUs need more juice, new wireless standards are introduced and multi-tasking becomes popular.
We've come from dumbphones (eg: the old Nokias) used almost solely used for calling and sms to phones that handle half the stuff in our lives, yet they're still using almost exactly the same battery technology to power it.
Simply put, the smarter the phone, the more power hungry it will usually be. And the Galaxy S is currently the smartest phone of the market.
Samsung compensated by fitting a larger battery, but they can't perform miracles with the aging battery tech.
Take a look at the x-ray scans and teardowns of the iPad; 80% of its internal volume is battery space to allow it to last for 10 hours! Sadly phones don't have the same space luxury without the rear getting chunky.
I'm hoping increased capacity batteries are released like the Hero had, as the Galaxy S is large but thin enough that some extra volume on the back wouldn't be much of a problem.

That is just fine! It's just the percentage guys.
Think about it this way.
Compared to the energy consumption of the display other things uses much less energy.
However on my Galaxy S, I played 6 hours (almost 3, 720p Movies) continuously. Isn't it just awesome on a device having 800x480 Crisp Display that only weighs 118 grams?

With brightness set to auto-brightness or max or min?
@OP - this is very normal. I always get the same type of readings.
Except when I talk(voice call) for a very long time.
Mine also same display always use up more then 70% and the battery can't even stand for 8 hrs, with very minimum usage 1hrs wifi, 20 min call, 1/2 hrs 3g, 1 hrs navigation(with charging). Have got battery replacement from samsung but still the same I read a post some where for UK set, the guy get 1 to 1 replacement, battery can last for 2 days for it new set, just wonder is it the flaw set we having that cause our battery drain? My friends told me that for his set from morning till after work (9 to 8 pm almost 11 hrs) battery only drop 10%. I really hope someone can help us to prove is samsung selling flaw set so we can claim 1 to 1 exchanges.
Hi all just wanted to do a comparison for battery life. I think that the biggest factor is having your display on and what kernal you use. So fill this out please so everyone can know battery life based on rom/kernal combos. :]
Samsung Fascinate
Rom: JTs V.7 DJ05
Kernal: Stupidfast 1.54
% battery remaining: 1
Standby time: 14h10m
Screen time on: 4h12m
Screen brightness setting: Auto
Setcpu: no
Settings: N/A
If you think theres any other factors to add just let me know.
I like the idea. Hopefully it is practical, so many variables. I would suggest streamlining the report a little bit, adding time spent without signal to standby, and changing SetCPU to be Extras: (only list items if you have them), live wallpaper, launcher, setcpu
Also I would add
Most used: Map 13%
Swyped from my i500.04 (bh &1129) using XDA App
Reports:
System: blackhole 2.2nf, jt 11/29 novoodoo
Extras: live wallpaper (Ocean Waves), adw, auto brightness, buzzbox news, accuweather quick, tweetdeck, google voice, goldenstorm Blackish v07 theme
Updates: Gmail (push), tweetdeck (twitter & facebook every 60 minutes), Buzzbox News (wifi every 30 minutes, vzw every 2 hours), Accuweather Quick (Default)
Report 12/3:
Display on: 5:23 (4% battery left)

standby: 11:12 (27% without signal)
Most used: display 69%, voice 8% (0:07:50), standby 8%, system 4%, idle 3% (5:20:56), dolphin HD 3% (0:17:22)
Report 12/8 (Total: 15:44:36)
Display on: 3:56:18 56%, (4% battery left)
standby: 15:44:29 15%, (35% without signal)
Most used: Media server 6% (0:46:30 - ran pandora a while off of speakers), System 4%, Voice 4% (0:2:40)
Thats awsome soba (gets off to try that combo now)
Ill just be stoked when we get froyo in twelve million years.
Froyo has increased battery life on my X by like a good 5 or 6 hours.
I charge my fascinate nearly twice as often

Hey soba would you say that Bh has bettery battery life than JT?
Well note that I am running JT's kernel. In terms of the ROM, of course I am very happy where I am, but not because I believe the battery life is superior. I did run super clean 0.5 no voodoo, but not long enough to make a proper battery life comparison. In fact, I believe comparing different installations to get a handle on battery life or perhaps some practices that might improve it is the intention of the thread.
Samsung Fascinate
Rom: JTs V.7 DJ05 with NexTheme v3.0
Kernal: 1203 Voodoo
% battery remaining: 69%
Time since unplugged (full charge): 12h 26m
Phone Idle: 11h 40m
Display on: 46m

Most Used: Display - 34%, Cell Standby - 34%, Phone Idle - 22%
I'm using Beautiful Widgets, set to update weather every hour, along with LauncherPro+ set to update Friends widget every hour (Twitter/Facebook). No Live wallpaper, minor gaming (maybe 10 min). Today has been a light usage day as I was busy with other stuff and had less time to play with my phone.
BlackHole 2.4 w/ DJ05, jt 1129 no voodoo:
4 hours, 1 minute display. 24 hours standby. 3% battery left. Just a rough estimate, didn't take formal report. Subjectively same battery life as 2.2 w/ IRC dj05.
im trying to compare battery discharge results using "battery monitor widget" app. the lowest sustained batt discharge i got from my note is -51ma while on standby with all connectivity off except voice. ive only installed battery widget monitor and antutu for now aside from stock apps. no config changed from stock 2.3.5 except syncing my google contact, mail and calendar
in comparison with my old moto defy, defy is reaching -13ma/-17ma as its lowest with live wallpaper, facebook and a lot more apps and config changed but still getting the abovementioned battery discharge result. defy is still at stock rom 2.1.
what's yours? would just like to compare since i noticed that sg note's battery discharge is faster while on standby.
I've gotten as low as 9, but I guess 11-12 is normal. I drop my connection to 2g unless I need 3g.
Unless mistaken, the Note is not fully supported by this widget and the mA reported is estimated, thus not really precise and fully reliable.
However, overnight (about 8 to 10H on standby with flight mode ON) I loose 2 to 4% of battery. It's really good !
