Longer Battery Life! - Galaxy S I9000 General

hi everyone,
i just wanna share my experience with my Samsung Galaxy S.
i have finally managed to keep the phone running with "normal phone usage" for more than 1 day
it is true that the multimedia features usage was to the minimum but still
2 Days, 16 hours and 43 minutes is an excellent number,
and still i have 15% remaining in the battery!!!
Check the screenshots below.
All what i have done is:
1- installed Voodoo lagfix
project-voodoo.org/download
2- installed Advanced Task Manager (ATM)
getandroidstuff.com/advanced-task-manager-android-download-v50/
And make sure to enable the Auto-End Running Apps features in ATM, i have used the 30 minutes frequency.
i am still unable to believe the difference that i got from this combination.
Voodoo has really fixed the lag issue and apps are running so smooth.
and with ATM installed the battery life has reached unbelievable numbers.
the installation for Voodoo was so easy and no complications, i have just used the update.zip file and it was so fast and easy.
check this yourself and tell me what you got from it.
cheers.
EDIT:
i forgot to mention that i am using ADW.Launcher instead of TWLauncher.

That's nice.
My record with light usage was 4.5 days.
In that particular case, I still had 50% after 3 days but made a lot of calls on day 4 so the battery went down quicker.
Key setting is to switch the phone to 2g when not needing 3g and also turn off the internet connection through the mobile provider and only use WIFI where available.

Very nice usage, but do you have push email active?

Congratulations abuatwan but i still think you could get longer from your battery. You say you have Advanced Task Manager running and set to start up every 30 minutes.
That costs power to start that up (as does any app) and when its killed whichever apps/processes its deemed to, if they start back up...well that's even more power lost lol
Android has its own task scheduler/killer built in and really all you are doing is battling your own system.
This will explain in much more detail, even if you don't understand everything mentioned read on and try to take in as much as possible.

I do agree though that with the galaxy, something needs to be done as it does in a way run better with a task killer (not counting the battles and power costs)
I use a free program called Auto Killer Memory Optimizer which tweaks androids built in task killer meaning you use your system as it should be
I've had mine running on 'moderate' preset setting for 2 weeks now and i wouldn't dream of installing any other task killer

The default setting for killing empty_app processes on Galaxy S is 48 MB. The moderate setting on autokiller is 40 MB, so you are actually *decreasing* the memory tolerance, making the memory management worse! I agree with you about the article, but with a strict setting you will see much better performance, try it.

My SGS keep 3 days max with normal use with disable the data connection with GSM and 3G

I do 2 days with browsing and stuff, seems my battery drains less quickly on wifi then it does with 3g or H =\ killing stuff with ATK is pretty handy as some stuff that i never use don't really mater to keep running in the background.

no, during this period i have turned it off, actually i have turned off the Auto-sync option.
i have played some games, used the browser (over Wi-fi) and used GPS but that was very minimal.

great,
if i can just change the default likker setings, i believe that will save lot's of battery
Definitely i will install "Auto Killer Memory Optimizer" and will try both profiles, the moderate and the strict.
Thank you

I do get this with my normal usage, 2 days and some hours - can't remember exactly. I have wifi on constantly, 3g when outside, autosync and push always on, autobrightness, no task managers or lag fixes.. Just stock JM2 :]

I have never managed to get more than a day's usage out of my phone. Today my display has been on for 1h37m and the phone has been off the charger for 5.5 hours, my battery is down to 66%.

good luck, in 3 weeks or so you'll need to do a factory reset because the SGS software/file system is a P.O.S

Ahh well that's new to me, Thank you Tyxerakias. I do wonder what else this app is tweaking then because using Super Manager memory widget i had noticed that i would get slight lag when swiping screens if the reported memory was showing around or below 70mb. The 70mb figure might be wrong as i use a lagfix but the point is that to me around 70mb showing = lag. After installing Auto Killer Memory Optimizer i would sometimes see as low as 50mb but still no lag. I got rid of the memory widget after that as it was just displaying useless info and taking up screen space.
I would be tempted to try the strict setting but my phone honestly flies on moderate and ive also heard if you set it too strict then it can end up killing off things like the clock which means your alarm will then fail.

why 3 weeks? are you referring to the Froyo update? and what is P.O.S?
Personally i wouldn't mind doing a factory reset if you ARE meaning for Froyo as flashing Froyo will reset it anyway...2 resets is no more loss than 1 reset if you are backed up and ready to flash

lol ahh i get it now, he means the file structure in the Galaxy. Samsung chose to use their own rather than a proper linux structure and i've seen many devs also saying how it was a very bad choice.
Well i've had mine for over 2 months now and no loss of data or anything yet so its fingers crossed here lol..........i will be backing important things up as a precaution too
Yes, that app is useful and i am confident you have noticed that

I don't use a task killer, they drain the battery.
I'm pretty sure you would get the same battery usage with screen on vs. screen on and movie playing. Playing a 2h movie drained my battery for 25%, screen on for 2h was about the same so...
I just use Juice Defender ultimate just to be able to select a few features:
- Activate Data/Wifi for 5min every 2h (would be better every 4/6hours but whatever...)
- Data / Wifi off when i sleep
- Leave data/Wifi on when the screen is on
Basically, my phone only syncs / uses data when my screen is on (or every 2h just to push emails if needed)
I noticed that this really really helped me. 3G and screen on really kill your battery

Opinion about battery life cyanogenmod 5.0.7

Hello. I need an opinion, i've been using cyanogenmod 5.0.7.
Just back to my home pc. After using for 1 day i must say that battery life is a issue. I really dont know what is. I've been monitoring all the apps. to see if there was any CPU change. Is LauncherPro responsible for battery drain?
In almost 13 hours the battery was reduced from 100% to 24% . My settings at SetCpu are:
Usualy have only 2G signal in order to save battery.
Sleepmode 128 as minimum and maximum. In normal use is 528 as Maximum and 245 as minimum ( i tested for 5 hours with 352 Mhz as maximum , anoying that the performance wasnt very good so i changed back).
Stock of new radio roms, have as default 480Mhz as minimum and 528Mhz as Maximum for what i saw in SetCPU last time i used the Sense UI 1.5 Stock by cursordroid. IT lasted me around 1 day and like 10 more hours with same use as this time.
I would request higly some opinion about this, so that i may know what to do in order to have a better battery life.
I used around 3 hours of music daily, near 30 min of internet (it varies according to my needs). Phone Calls (around 1 hour at max). Some text messaging. And 20-40 min of playing games and checking apps for fun entertainement (This i dont do daily but since was todays use i leave here) .
Also noticed as stated above about the Signal reception (reception is in maximum but call gets lost easily compared to a normal ROM and new radio (not sure if is only new radio)). Is alot worst than usual. I dont know the reason. But with sense ui worked perfectly well.
I think these are the most important issues wich must be dealt with in my opinion and i hope next release will be accounted.
Battery life and signal reception or if you can help, and sorry if this is not a issue of the rom, a possible solution.
Thank you!
Some battery saving tips:
- Go into spare parts and make sure the end call button makes the phone go to sleep.
- Turn off market notifications (Go to the market, then downloads, then hit menu and then notifications).
- Turn down the brightness as low as you stand it.
- Kind of an obvious one, but get a task manager and periodically kill apps running in the background that you're not using.
- Speaking of apps running in the background, lower the refresh rate of apps to as low as you can. Or simply turn off background data use and refreshing entirely.
- Turn off wifi/bluetooth/GPS when you're not using them.
- Use as few widgets as you can.

This is plain WRONG.
Do try ADW Launcher instead of Launcher Pro. It won't help with your reception issues though. I had the same problem with CM on old radio. The other was GPS (didn't work).

Apps running in the background = better battery? Please explain.
i'll try as you suggested. it is very important. i'm testing now the port for new radio. Reception is great compared to the one before.
Lets see how it works for now =) I'm waitig for new update seems there is some battery drain issues going on CM 507
Also try using CM 5.0.8 test 1. I've noticed improved performance. I came across one thread that also suggested the Facebook program was causing drain. By turning off all the Facebook sync and notifications, I'm highly improved battery life.

Most apps that are in the background aren't running, they are sleeping and not using any CPU. For continued background activity the app would have to implement a service, which would be pointless for most apps.
I get 10 hours out of mine with complete eclair, and setcpu at 245 min and 614 max...Its stable and I do about 3-4 hours of music, moderate texting, and 115-30 min of web browsing of 3g...Oh and I only have about half signal.
507 was killing my battery... 508 seems to be better so far
actually after a experimenting 508 isnt that great either... it lasted about 11 hours... a listened to the radio most of the day and a few songs for about an hour... one phone call for about a minute... and its dead
the best Cm 5 battery life for me has been test 7...
Hmmm I look at it this way, if you clock to low it will take longer to finish whatever process its doing and will kill the battery faster, if you clock it to you, you will be poring to much voltage towards the cpu killing your battery...Idk if mines is best but its clocked at 614 and has been great so far.
I'm using CM 5.0.8 t1 and battery life is great: 24 hrs+. I DON'T use Facebook, Twitter, SMS or Market update check. I do sync Gmail, contacts, calendar and weather. I do use some internet, not a lot.
Wrong
Never use a task manager. Applications running in the background doesnt mean that they are running. The might be sharing resources with another ( or sharing threads). So never killl apps. Android has its own service manager which tells the phone to run on optimised settings. Killing a process will again require the other app to start again.
Uninstall your task killer and feel the difference

Correct, just like windows, and force closing some apps can cause the o/s to become unstable...

ATTENTION! Xperia X10 battery problem SOLVED once and for all! Not kidding

Hi fellow Xperia X10 owners!
Ive got my device now for 4 weeks and in the beginning my battery only lasted for like ... 5-6 hours max ? I got so annoyed i did some research on how to solve it, and to be honest.. ive seen MANY post and MANY solutions but none of them really worked or they were not explained detailed enough to make any sense .. after many useless tweaks i got my battery to last like 12 hours, and that is by just making like 1-2 phone calls and some messages, nothing more, left aside when i made photo's or used the web... so my device was still useless.
Then i started using "advanced task killer" and the auto-kill feature, but that didnt realy solved much so i installed "task cleaner" but that didnt do much either.
Now after 3 days trying to find out what the problem is, i finally came to the solution !!!
Many post suggest using "advanced task killer" but none of them really gave the perfect settings for it, well i finally found them out myself
The settings i use : Auto Kill Level ==> Aggressive
Auto kill Frequency => When screen off
Security Level ==> Low
And now for the first time EVER! my phone can last like 3-5 days without recharging!
Additional tweaks are: 2G only
disabling WIFI and Bluethooth
disable GPS and positioning
Disabling these 3 doesnt realy make any problems since you can access them quickly by using the "networking widget" so i dont care
also put screen brightness to auto adjust and all these other minor things you hear in all the other posts, i am not going to list them once more.
Ive made some photo's for you to see for yourself
I'm a new user so i cant post links yet.. so you will have to copy it
w w w.photoshack. com /index.php?cat=26302 (kill the spaces)
I'm not trying to fool you or anything, i'm honest
(its in Dutch btw)
Time since last Charge says : 4Hr 14min 11sec
And my battery level indicates 100%
At this moment it says 5hr 9min 10 sec and i just entered the 99% zone
i didnt really made any calls or anything, i just checked once in a while how my battery was doing so it was basically running idle but i am still Very impressed!
I'il let you know how it turns out tomorrow etc, after ive made some calls and stuff
Good luck to all of you and i hope your search to happiness is finally complete!
And yes i'm dutch so dont blame my spelling ^^
Regards, clintax
thx for your info, i'll try your setting now
interesting idea, but I think we need to go through the list of what it is closing down in case you want to keep anything running. I Will test your settings and see how it does.
I was just using Kill level - aggressive with security level - medium and it was doing ok. Nothing spectacular but at least I could go all day without needing a charge or battery swap.
i was wondering. What exactly did you auto kill on advanced task manager?
I keep looking and looking there is nothing particular i want to kill.
I'll try this out and see how it goes by tomorrow. And by the way are you using helix launcher, gde or anything? Or is this the only thing you're doing?
I set the level to medium instead of low, we'll see how it goes.
I've followed all of your guidelines, but when I set ATK Auto Kill Frequency to "Screen Off", it immediately turns the screen back on after turning it off. After letting it sit and naturally time out screen off, it immediately turns the screen back on... Vicious power-draining cycle.
Is there some other tweak that I'm missing in your post?
@clintax, I'm pretty sure that the real reason that you see this improvement is because you have basically disabled all your networking facilities.
I have wifi turned on (never turn off when plugged in), GPS is turned on (which is the best because it doesnt consume any power unless some app uses it), bluetooth is off (but can turn on on request via settings widget).
My phone lasts me over 12 hours, which is sufficient to cover a normal work day, I use it in the metro to read books, I check news and feeds occasionally. I use push email so that I get instant notifications.
Personally, I dont think using task killer applications to kill apps is the only factor in the improvements you report. Usually, whenever I check my battery usage, applications+android system are usually under 5% in total.
I'm pretty sure my battery will last longer if I follow your example, but my phone wouldnt be half as useful as it is now. I really dont mind charging it overnight.
Cheers!

followed your instructions but didnt get help. actually, my major battery drains on radio and standby. the 2 items always takes more than 50% of the total drainage.
look forward to the comments from all of you.
Didn't see any improvements either. I usually get 25h+ without running any task killers or start auditors, with 3g always on and medium to hard usage of the phone, which I'm pretty happy with. So I think its the settings of the data and radio that drain the battery, not the applications.
As a fellow Dutchman I'll share my part
Well I've tried most stuff already on my X10 and the only stuff I can really find that drains my battery are faulty apps (or at least in combination with the X10), GPS and searching for network when I'm out of reach (which is seldom).
I've currently disabled Beautiful Widget using the Startup Auditor, because at some point it starts killing my phone by running 100% and not letting my phone go to sleep. And this is what I meant by faulty apps (or in conjunction with the phone/OS).
3G is always enabled (what would be the use of this phone if you would disable all features which makes a smartphone useful).
Network based location enabled (now using it for the Weather & Toggle app).
No taskkillers running whatsoever.
Running Helix Launcher2 as home with seven screens.
Sending 20 to 30 textmessages, browsing the internet for 30 minutes (half with wifi/ half without), some calls about 30 minutes, toying a lot on the phone two hours plus, some Google Maps navigation 15 minutes with GPS enabled.
This will get me two days of usage easily.
Oh and running R1FB001 at the moment but had these results already with the R1EA016.
.
well yea, i installed helix launcher yesterday but i uninstalled it right away because i didnt like it so much.
Well to be honest, before i used the agressive settings etc on ATK, i used the same settings on the rest of my device
Wich are
-Only 2G
-No WIFI or bluethooth on
-Gps off
-autosync off
-dissabled auto-update, and put it on manual
-deleted the cash of moxier, timescape, mediascape in settings->my applications, and removed there icons from the homescreen
-screen brightness on auto
I suggest you take a look at this video from sony, wich explains it more detailed
(cant post links yet)

and my battery still drained atleast 3-4% hr if not more, it is only from WHEN i started using these settings in ATK that my battery life improved like 500%!
BTW as for what features it kills by doing so i dont know yet, but at this moment everything still works perfectly
At this moment i have 14hr 23min 31 sec and 96% battery left, i'il post another pic for you guys.

Well the important part off all this was Security Level ==> Low
it shows you like 3x more things running on you phone then normal, and i just killed them all except: Ignore list= ATK, Xperia Flashlight, Alarm, VizBattery, Handcent Sms and taskpanel, but i dont realy use taskpanel anymore
I am still trying to find out what it actually kills in particular but i heavent found any problems yet

I had two "battery cycles" where the battery lasted 48 hours with my normal usage (Moxier+Gmail in push, 3G data, no WiFi, some Bluetooth while driving the car, no GPS). I noticed that because I usually have a 24 hour duration, and at the end of the day, when I put the phone charging while I sleep, I still had more that 60% of the battery instead of the usual 15%! So I decided to not recharge overnight and so I get about 48 hours both times.
The third cycle lasted even more, about 60 hours!!!
However, starting from the fourth cycle... back to 20 hours, or even less... I have not changed anything, I'm not even using task killers... I really don't know what is wrong with this phone (the problem is not the battery itself, I tried with 2 original SE battery + the mugen).

Wow, the performance is just amazing. I suggest you start to use the phone instead of keeping it idle. Then you can share with us how the battery performs, thanks.
Which version of Advanced Task Killer are you using? as i have just checked mine and do not have the option to kill when screen is off
I have version 1.7.4 build46

Ok, so with the settings I used over night, I had a 5% drop over a period of 7 hours sitting idle.
Auto Kill level - Safe
Kill Freq - When Screen Off
Security level - Medium
BT, WIFI and APN - disabled.
I had a 1% drop in like 6/7hrs.. fell asleep whilst using xda, 3g was still running an all..
I just use taskpanel
Wifi, gps, bluetooth & auto sync off
also Adw launcher
Edit.. Firmware 016 (only cause I can't remember the rest lolz)

Memory Booster (120 mb-180 mb)

Anyone used this app? I tried it and it boosted my memory from 123 mb to 180 mb.
i know "if you have free memory you're wasting it". but in my opinion this combined with advanced task killer will improve battery life a lot.
its on android market, just type memory booster
Lol I experimented with these kind of apps, my opinion is that they are pretty much pointless.
I simply tell things not to auto update and removed unused junk.
Did the trick for me.
Swyped from my rooted X10i using Tapatalk.
I'll bite. How will having more free memory improve battery life?
You don't need third party apps. You have to determine which app is eating your battery life. The only thing memory booster is doing is disrupting Android's memory management processes.
Sent from my SAMSUNG-SGH-I897 using XDA App
if it could activate the full ram potential of the handset then it would be worth while but i dont see the point in the extra mem for app's.
Like I said I simply stop stuff auto updating and therefore save battery life as no apps are active, merely sitting in ram.
Swyped from my rooted X10i using Tapatalk.
I only kill programs when I want my phone in standby because I know I won't be using it. Or with programs that can still run in the background and stay active when they shouldn't.
Other than that, don't be a frequent task killer. It's not an iPhone, it's an Android phone. As much as I loathe my Xperia X10 it's far better than an iTurd.

Way to try to prove your cool by trying to inject irrelevant crap into the discussion. Especially ****e you obviously know sweet fa about. You do realize that when you get down to the nuts and bolts the memory management is almost identical in iOS and Android? Only difference is how it's exposed to apps. My gf has my iPhone 4 now, trust me, calling it an iTurd just makes you look a bit special - and not in a good way either.
P.S. task killers made sense on phones like mt3g that were memory limited, when you went to launch a big app like gallery it popped up straight away if there was free ram - when memory was all spoken for, the system would have to kill a bunch a tasks, so it'd hang for a while before launching your app. Can't say I noticed the need for that on my X10.

It isn't the free memory that saves battery. It's the applications being "killed" that otherwise would need some battery power as they lie in the background doing things. Even sleeping applications have some "attention" from the kernel and that will drain (slightly) on the battery too. Every drip-drop counts.

And every time you want to use an app, will have to be reloaded in memory wasting more power for that task.
Anyhow, do it your way ...
The rest of the world is just stupid.
This constant debate of whether app management apps work or not is really irrelevant. Some work, some don't. Just try and find that out.
Once I listened to posters here and decided not to use ATK because of the reasoning that Android is efficient by itself. Wrong. My battery kept draining fast. Once I started using ATK and modifying the program here and there, my battery's energy consumption actually slowed down and I can go through a whole day without charging. My settings? Put ATK on safe mode and auto kill every half hour, and ignore SE's own backup app (for some reason, killing SE backup caused a disruption with the data/signal for a second).
So for everyone, just try and see whatever is recommended works.
Exactly my point. I used to use atk with similar settings to yourself and experienced greater battery drain.
I get better results with my method.
We all use our phones in different ways so it follows we would experience differing results.
Swyped from my rooted X10i using Tapatalk.
I'm trying to figure out how some people drain the batteries so fast. I have my phone set up as a wifi accesspoint, I'm using bluetooth, autosyncing my gmail and calendar but still I get more than a full day use out of it. If I listen to music over a bluetooth headset constantly I can't last a day but the juice in my headset tends to run out faster.
I can't for the life of me figure out what people do. I'm not using any task killers or what have you but still get between 18 and 24 hours of heavy usage.
I was using a task killer before reading on here about how they are useless and whatnot. But I find my phone freezes up more now that I am not using it. The battery seems to be around the same. All I do is text and use facebook and it seems to freeze up when texting or typing half the time. I am kind of wondering if it's because I text so quickly..
Just to clear things up a bit:
Many applications out there are bad.
Applications that are some real heavy battery hogs, even when prefetched in the background.
Those bad applications keeps downloading adverts now and then, executing instructions while in the background, and so on. Those applications doesn't have any sleep/standby routines , or the routines are empty.
Some applications are so badly written, they're running at "full speed" no matter what. Those extremely bad applications keeps the CPU at full speed even when in standby mode.
A good sign of this is when the phone gets hot, even when not used. It's the CPU that heats up the device.
The programmers of these bad applications have no whatsoever experience with Androids "sleep and standby" functions and therefor left them empty or half-done.
This is why killing applications helps for some, and not for others.
It all depends if one got one or more "bad" applications installed.
And Android aren't too smart either. It'll just prefetch, to what it seems, a random bunch of applications.
For me Android prefetch apps I rarely use, and skips the applications I use everyday. Weird?
If one would keep the device clean and keep those bad applications out, (of which noone can tell if it's a bad app or not. There's nothing visibly wrong about them) one wouldn't need a separate task-killer. Or if EVERY single application out there where perfectly written, accordingly to the Android model.

Any tips for a better battery life...?

What settings is everyone using to get the most outta there desires hd battery!?
I know it will take at least 4 cycles to get the best outta the battery, but at the moment I can literally see the battery draining, its not good! I lost 30% within an hour and half! :0(
I'm using advanced task manager, and it never seems to kill all running apps straight away when I hit end all!

1. Dont use task killers...it doesnt work with Froyo and it doesnt help...uninstall it.
2. Empty the battery to the 0% and leave it on charge when phone is off all night.
3. Turn it ON and use it untill it die again...then again turn it off and charge it for 3 hourse. Turn it on...its calibrated
4. Use 2G if you dont need 3G
5. Use max 70% of display light
6. Use only must have online update programs
Thats all...I did that on HD2 and I didnt have any problems for all day...and I used it normaly. In stand by it was 1,5% per hour... with mp3 was 10% in 1hour...etc...
Have fun!
How come task killers don't work? How do I stop apps from running in the background now then without a task killer? Won't this kill the battery more??

No it wont...its like using a notebook... if you have notepad, browser, and solitair opened...but not working with them...they will not use your processor and energy...it will only use your RAM memory... And thats the same with android..BUT after some tome (for example 6hours) if you dont use some app...the phone will automaticlly turn the app off. And in any posiblle way you would never use more than 400MB of 765MB RAM ...so memory is not a problem

My first post here on XDA so hi
Now, I'll just correct you a little. Your example was pretty much correct and a nice one, but Android OS doesn't kill tasks when amount X of time has passed. Android kills tasks when it needs more RAM (=when there are too many processes running), it kills the least used process. Android OS usually runs loads of different processes, the cool thing is that they don't consume any battery because they are not actually used. These processes are stored in the phone's RAM memory, whether there is something stored in the RAM or not, the RAM chip uses the same amount of electricty. Thus processes that exist but are not in any applications' use, don't consume battery. Therefore you don't need a task killer, in fact a task killer reduces your battery life because it kills the processes and then the phone has to restart them, and this cycle continues over and over.
So which is the best way to come out of an app? Back button or the home?

Both are as good, it makes no difference.
I have found that turning auto sync off when not essential saves my battery quite a lot. If I need to check something ill refresh that app. Once I'm near a place I could charge ill switch it back on.
Just a suggestion. Try it and see how it goes for you..

How do i turn off 3G and use 2G network? And how do i turn on 3G when i want to use it?
For some reason after a hard reset everything seems to work fine. Sms messages receiving in time (had installed task killer which i think made the problem possible) and all of a sudden 3G and HSDPA is available. So battery life all of a sudden is less to so how do i change this?

You can go to settings/wireless and network/mobile networks/network mode/gsm only
You can also install extended controls widget wich has a widget wich takes you directly to that screen. A direct switch is not available in this ROM.

Welcome on XDA!
Do you have a source esp. regarding this piece?: the cool thing is that they don't consume any battery because they are not actually used.

Thus processes that exist but are not in any applications' use, don't consume battery
Circle battery mod
This is still kinda on topic, but I find it's much easier to get a feel for battery life, or what's using it all up, if you have something that actually gives you values all the time. I have a circle battery mod, but a percent meter or widget is just as good. It's nice to have it in your face, instead of either intuition or constantly going into your settings to look up the value.
Just my two cents!

[FIX] Battery drain from Awake bar constantly on

First and foremost, this will only apply to you if you have seen the following symptom:
You go to Settings -> About phone -> Battery usage -> click on the graph above and see "Awake" as a solid bar instead of (mostly) lining up with the "Screen on" spotted bar below. Here's my previous thread of when I discovered this issue when my "Awake" bar showed solid for an entire 8 hours when my "Screen on" would show frequent off/on's:
http://forum.xda-developers.com/showpost.php?p=13938317&postcount=772
I found my SGSII was getting decent battery life, but idle was certainly worse than my SGSI. I couldn't figure it out for the life of me what could be causing it given I was running the exact same apps as my SGSI 2.2.1 handset, but the solid Awake bar did not sit well with me.
Observations:
1) After 8+ hours of solid Awake, I would have no apps running under Settings -> Applications -> Running services except for those that I normally would expect in the background... Settings, NoLED, Google Voice, Swype, etc.
2) I noticed that under this "Running services" screen, if you hit Menu and select "Show cached processes," there are actually other cached processes that are in a semi-dormant state. Are they running or are they not? Hmmm....
3) After a system restart, the Awake and Screen on would line up once again.
Suspicion/Hypothesis:
Some app that I normally have running... even if I completely exit out of, it would sit under cached processes and somehow still keep the device awake.
Testing:
First, wanted to see which app when normally running would keep the phone "Awake." After a few days of testing, isolated it down to eBuddy, which is a chat client I used to have running nonstop on my Froyo SGS. So, after several hours of running eBuddy and seeing a solid Awake bar, I exited out of eBuddy properly (Menu -> Exit), ensured it was no longer running under Running services, and tested it for another 4 hours. Sure enough, with the device mostly idle and eBuddy shutdown, the Awake remained solid/on!
So, I then revisited Settings -> Applications -> Running services -> Menu -> Show cached processes, I saw eBuddy was still cached and taking up memory. So, I clicked on the process and chose Force stop. Afterwards, I let the device idle for a few hours more, and the Awake and Screen on lined up once again.
Conclusion:
I'm not sure if this is a Gingerbread bug or eBuddy bug or a combination thereof, but something changed in the code from Froyo to Gingerbread. Probably has to do with this caching feature, but there ARE apps out there that will keep your device constantly on even if you do properly exit out of them.
Solution:
I used to run "Advanced Task Killer" on my SGS with Froyo but never bothered with Gingerbread because people much smarter than me on here have said time and time again "it's not necessary for Gingerbread, you're wasting time/battery life." Well, that still may be true, but given there are these rogue apps that will cause Gingerbread to stay constantly awake, Advanced Task Killer is the best solution at this time.
(It may not be pretty, but hey, it works.)
So, I installed Advanced Task Killer, did a fresh boot, put all the system apps and other apps I don't want ever shut down (Email, Swype, Settings, etc) on the ignore list, turned the kill setting to every hour, and let it sit. I can say for the past 2 days, my idle battery life has improved significantly. Normally by the end of my work day, I'd be skimming along around 40-50%. (Keep in mind, I use the phone primarily for business, which means 2 push E-mails, 2 pull E-mails, constant text messaging, and lots of phone calls.) The last two days, I have been easily at 70-80% by the end of the day. For instance, right now at 4PM CST, I am still at 82% remaining battery.
Also, keep in mind, I have just about EVERYTHING else I don't need frozen/uninstalled through Titanium backup. This includes but not limited to WIFI Sharing, all the hubs, all the readers, all the SNS junk, AP News, Accuweather, etc.
And the most telling bit that the fix is working: My Screen on and Awake line up perfectly with no more solid bar for Awake. And, this is even after running eBuddy last night.
I know this won't help everyone, but hopefully, it will be of use for some of you. Good luck!
If you're managing to kill apps that keep the phone awake, does it prevent you from receiving messages on eBuddy when the screen is off?

Interesting question. I had Advanced Task Killer running all last night, and I woke up to messages in eBuddy in the morning. So, my immediate answer to you would be "no," but this will probably take more testing.
Maybe, I'll set ATK to an aggressive 15 minute kill, and have someone message me after 15 minutes of idling with eBuddy running...
I have noticed that with eBuddy actively running, you cannot select it under ATK and kill it. You must exit out of eBuddy properly (Menu -> Exit) for its active process to shut down. Little did I know though... it would still float around in your "Cached processes" afterwards and keep your device Awake!
Well I've been using ATK since this morning and I can't find any change in Android OS ..
It's still high..
Anyway ATK reports that all the games I downloaded from gameshub are active..
And even if it kills them, they appear again in like 10 minutes.. It's really wierd

I don't use game hub, but I do have a bunch of games on my device, including the larger Gameloft games. And, I can say for a fact that I do not have any of them ever running in the background.
Something else is keeping them alive, and has nothing to do with ATK. ATK will only help to kill cached processes, but if something is launching them again, that's what you need to look into stopping.
Well.. I do not like tools like the Advanced Task manager.. BUT looking at battery drainage it seems to do wonders!
8 hours of light usage (display 45 mins) --> 75% battery left
3g on (with JuiceDefender à 30 mins) + sync (so I receive whatsapp messages & mail etc)
Listened to music / radio for about 1-1.5 hours
Android OS is sadly still at 36%, Display at 22%
But this I can live with !
Thanks!
[edit]
It would obv. be nicer to be at 80+% without that Android bug... Ah, and I did delete / freeze all that Samsung crap with Titanium, didnt really help much! I can also recommend getting CPU spy to see how much your phone actually is in the sleep mode (around 80% for me!)

Yeah, I wouldn't run ATK unless I absolutely have to. Like I said in my first post, it is a "brute force" method of ensuring apps are completely closed out and there are no rogue cached processes keeping your device awake. Since I've installed it, the "solid Awake bar" phenomena is completely resolved... and in return, I get much better battery life.
And yes, this is of course on top of freezing just about everything Samsung and anything else I don't need or care to use.
Couldnt agree more!
One questions, what is your "Android OS" % at?

Uninstalling/freezing rogue Samsung apps is a must
ONLY THE COMBINATION WORKS and it works well indeed.
Mmm bizarre! I was waiting for the hordes of people telling you that 'task killers' are unnecessary and stupid.
Thank you very much for your findings.
On my SG2 The android System process is eating almost all my battery! any solution for that?

Glad to hear it's working for you guys. With Advanced Task Killer running in the background, I haven't had the "solid Awake bar" reappear again... my Awake bar is always segmented and match up fairly well with my Screen on bar.
Idle battery life is very much acceptable now and definitely no worse than my SGS.
I've always enjoyed your posting and i'm glad you didn't just jump on the bandwagon like everyone else. This is definitely the type of posting we need where everyone work together to solve/identify the issues at hand.

Appreciate the kind words. Like I said in my first post, many people much smarter than me/in-tune with Android have said it's unnecessary. But, you're right... there are way too many "DO THESE STEPS AND IT WILL FIX EVERYTHING" posts on here with 0 to little evidence to back up the claims. In the end, nothing beats thorough testing and proven results.
I for one hope 2.3.4 resolves this bug... ultimately, I'd like to not have to run ATK altogether. But for now, this is a solution that works.

It works with Freezing/Uninstallin Samsung "bad apps" (WiFi Sharing, Social Hub, etc.). I suggest you emphasize that more in your initial post.
ATK itself helps but ATK is always late (30 minutes or one hour).
That's what I recommend to freeze/uninstall without crippling core functionality:
1 WiFi Sharing and WifiManager
2 Samsung apps (Social Hub, Days, Yahoo Finance, AP News, Games Hub, Readers Hub, Music Hub, AccuWeather)
3 Voice Command Uninstalled using Titanium
It's based on my testing using OS Monitor / ATK - those apps tend to wake up phone for no reason even when you don't use them.
Now it's 24 hours with 4 hours of screen on, no Juice Defender etc.
It works better than SGS (one) despite huge screen and excellent speed.

Well, freezing and ATK are needed to reach 2 separate goals:
1) Freezing: Needed to completely disable apps you plan on NEVER using.
2) ATK: Needed to completely close out apps you DO use when they stay cached/rogue in the background and keep your device awake.
So I do agree with you, freezing is absolutely necessary, but it really is the bare minimum. You still need ATK on top of that to actively seek out and kill battery draining apps.
I can confirm, OP solution works great on me. Thanks..
