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.
I have seen many posts about the poor battery life on the ADAM when in heavy/normal use. I have seen very bad battery drain just in standby/sleep on all the roms I have tested (Stock Newest build, edenx, and now CM7). SetCpu currently doesn't support profiles but I wonder if the processor still runs heavily even when in standby.
I should note that i usually turn off WIFI when not in use and also background data sync.
Pixel Qi Wifi.
As usual, after unplugging the device in the morning and not touching it for 8+ hours, it has about 50% battery left and battery history shows Phone Standby using all the battery. I guess these quirks will not be resolved until Honeycomb if ever.
Which do you mean "cell standby" or "phone idle"? I have the same model and the battery still drains more than expect overnight, but notas much as 50%. Did you apply a fix to remove cell standby?
Phone idle is what is reported. Here is a more specific example: on battery power for 10 hours today in standby with wifi off and background sync off and the battey is down to 55%. This is not a huge problem but I dont like to leave it on the charger constantly when not in use.
Kill the "phone Idle" <- that's really draining and if you don't use SIP on a WiFi only you can de-install phone and phoneprovider
2 other things you could try,
Install from the market:
"autokiller memory optimizer" and
"Juice defender"
They seem to help for me.
or use BEAST ROM 2.2. My ADAM batterie status is after 23 hours on 36%.
Hi guys,
Hope you all doing great.
Guys i have LG V20 n using from last year. It was working great without any issue. Battery timing was awesome. Giving me 5:30 to 6 hours screen on time. Almost day and Half on normal use. 2 days back something happened no idea what. Now phone idle using more then screen on time and wifi is always on even its off. I tired to uninstall app, then factory reset but still same.... No luck.... Any solution ??
Go to your location setting use the tab in upper right, click setting and turn wifi scanning off.
I tried this but no luck
As i mentioned i tried everything thing, like location off, wifi and Bluetooth scanning off, play services off, Almost everything is off, but still same. No luck...

Try to install battery monitor application (I use betterbatterystats) to find out what is causing your idle drain. But to be honest, I've never got 5-6 SOT. My idle drain is about 0,7% per hour with greenify, managed Google play services wakeup, custom kernel, kernel adiutor and about 80 apps on board.
I'll try and help the best I can..
Within the last year or so..I have been reading about this issue quite often. That is, people posting about "Phone Idle" having high percentage in battery stats. And then they are off to hunt down the culprit. The truth is, "Phone Idle" is NOT eating up your battery. Phone Idle is just that.... Time the phone has spent being idle (being still, or CPU/Battery not being used). Or in this case, percentage of total battery "usage" that belongs to "Phone Idle". In actuality, phone idle isn't "using" anything. The "usage" for phone idle is really time NOT used. A higher percentage is better. If your phone sat for 2 days straight without being used...the phone idle % will be real high. Also, you can't "Greenify" phone idle. You only greenify phone idle when you greenify other apps.....think about it.
And as for Wifi. The Wifi radio on this phone is a bit more power hungry. It doesn't even include any power saving options that some phones, like my Samsung S4 has. My S4 used on average from 2% - 6% depending on signal strength. The V20 can use from 7% - 11% ..again depending on signal strength. If you leave Wifi on overnight and it's in bad proximity to the router..10-11% is normal.
What is your average signal strength for your 4G and cellular (calls)? CDMA has 1X, I'm not sure what GSM uses. If it's in the high 90's and higher, that right there could be chewing up your battery. Phone radio often doesn't even show on the usage list.
How often do you need to charge? Also how much time between a charge and what is your usual screen on time now..after you wrote this post? Phone idle is only at the top because the "idle" time now exceeds the amount of time you have your screen on. ......don't take this the wrong way but some people think the phone idle is actually something that's draining the battery. It's not..it's just placed within the list. Ignore the Mah it shows for it. That just assumes it's some app and it tries to convert everything into mah..and I really don't know how accurate that is. But it obviously doesn't apply to Phone Idle. Speaking of...what is the amount of phone idle time?
