5.24 hours of display with it on. 7.54 with it off. Explain? These were the only changes I made from yesterday to today. I calculated these times via percentages and battery used. If everything remains relatively constant, power saving mode is worse on the battery for me.

battery saving mode - you mean in the display options? Yeah, I disabled mine. I would think that constantly checking images to determine brightness would use more battery imo.
how is this different from auto-adjusted brightness? i assume auto-adjusted brightness uses the sensor, whereas this battery saving mode will change the brightness by determining the content shown on the screen?

Ya so it needs power to keep the sensors awake. I always disable such functions together with auto sync. Just do it manually if you want to conserve battery.

going further with that, what all does auto-sync entail? is gmail pushed, or auto-synced? i don't really use any widgets or apps that would require it (maybe google voice? i guess calendar and contacts...)
Either way, I wish I would have known about this considering it added two hours to my battery life.

Ya it's good to know. I think a lot of people may get tricked by the descriptions. It probably only saves battery if the screen brightness is set to maximum all the time.

It's auto synced by default with or without the widget. (Things may be different in 2.2) If you want to sync them manually, you need to go to setting>accounts and sync and choose it yourself.
Thanks for the tip!
just curious - are you sure battery was totally drained?
that other post about the batteries having more life than indicated (and i'm not referring to the icon up in the notification bar) http://forum.xda-developers.com/showthread.php?t=770207
i've been wondering how accurate the battery remaining indication is, the one in "settings > about phone > status" actually is
after the battery had settled in (used for 2 weeks) mine demos a 1-2% drain overnite consistently, except for the blue moon occasion it demos 11-12% - and the issue i have is, every nite when i take it off the charger, i check Flight mode, and kill any syncing as well as kill the GPS. I know an errant app could be trying to run, but i don't think so - i've got Startup Auditor, and all settings have remained the same - there's no reason i can see for the odd jump in battery drain
i know the radio's signals strength in the same settings > about phone > status is way off - even when showing 0 signal strength & 0 asus, i can still make calls with no issue. It's just got me wondering how off all those indicators are, whether battery, radio, radio signal strength, system useage numbers, etc
did you run movies etc after battery notification came up to see if battery was truly close to 0%?

I'm using battery indicator. It has been dead accurate for three weeks. I'm getting two more hours of display which translate to considerable more overall battery life.

the "power saving" mode is annoying, if only for the fact that i had already disabled auto-brightness, only to realize the brightness would change depending on what was being displayed on screen at the time. i left it on the absolute minimum brightness, because that is more than enough for me, and the fluctuations were making me scratch my head for awhile there (thinking, "hey, i thought i turned that off!")
makes sense now

The battery indicator for me is pretty inaccurate, I've had Youtube playing with the speakers on, i.e. headphones unplugged a good 10-15 mins after the battery indicator was flashing at 0%. Another weird thing is I get more battery life out of Bionix 1.91 than Fusion 1.1, but Fusion 1.1 supposedly has the leaking battery while idle fixed. I dunno what's going on with the battery indicator but I can't believe it to be very accurate.
And spare parts doesn't work. Any other way to check what's keeping it awake?

try installing aLogCat and see if there's anything fishy on the logs (namely programs trying to background update more than they should... Java exceptions can often be a source of resource leakage if not handled correctly by the program that throws them).
WatchDog is also a good tool to see what's taking a toll on the CPU. I once found out that WeatherBug would keep the CPU topped up if kept in an area without internet connectivity as a result of some mishandled code error or something.

Hi. I am having similar problems. I downloaded Watch Dog lite and have used Battery Usage to see that Android System is using much of my battery even when asleep (overall, it is about ~46% of usage).
I have Wi-Fi turned to "Never On When Sleep" (or whatever the setting is) and I've noticed that when I look at Battery Usage, the blue bar that corresponds with Awake is nearly identical to that of Wi-Fi. I've also noticed that when I hit the sleep button, and create a break in the Screen On blue bar, there is not an immediate corresponding break in the Awake or Wi-Fi blue bars despite my settings. Is this normal?
Any help would be greatly appreciated.
what I can't tell is the difference between awake and up time...with the evo it was blatant but I can't figure out if the phone is actually "awake"
I think "Up Time" is time from last reboot and "Awake" is time since the phone is pulled out of sleep (either by turning the screen on, syncing data, background data collecting information, or etc).
Hopefully I'm correct...

That IS EXACTLY CORRECT. you get a cookie.
My NS4G is having problems sleeping, as well. Seems to be awake around 25% of the time, whereas actual screen-on time is about 10-12%.
I was having a problem with fast battery drain on my SGS2. I would get 15 hours if lucky from a full charge with light - moderate use. My most recent charge looks like it has doubled the time.
What did I change? I did a factory reset and manually installed all my apps, NOT using titanium backup. I had used titanium backup to restore apps only, that were from my previous phone (Nexus1). I have never used titanium backup for system settings, only apps, but it seems even that is unreliable. I've now stopped using titanium backup completely.

If you notice a higher battery drainage than normal then you have to see what application you've installed lately. If you can't find it then the only option is to do a Hard Reset. That has worked for me, IF your battery is drained by some app which you've installed lately.
Regards.
I am sure battery drain has to do with the apps we installed and the settings we use.
We are in a fortunate situation that my wife and I have both S II, hers is 2 days older from the same shop, so I assume both devices are from the same batch. Hence no hardware difference.
I installed a lot app and played with lots of settings and if my wife like it, she "demand" to install it on hers too, so hers is a more controlled env.
For some reason my battery drains a lot quicker than hers. I still have to find out which application / settings cause this.
For an experiment, we did not use both phones for a full day (very difficult), so all the drain is due to background processes.
There are several dips in the graph, but those are explicitly usage of the phone for a while. The big last drop on her battery was because she was playing a game for more than 3 hrs.
PS.
A collegue of mine (also an SII) had his battery run out quickly, until he found out his culprit: Settings->Location and security->Use wireless network was ON.
You can see the effect of this as the "almost horizontal bar" in my wife's battery when we turned it off.

I wonder if having 3rd party launchers like launcher pro drains the battery quicker. I installed launcher pro without ever having really tested the battery life of the phone with the standard launcher.

The screen shot on the left is your phone correct? It looks like something is waking your phone up and leaving it in an awake state for far too long. Your graph represents over a day's time and I see those huge chunks of time where your screen is off but your phone is awake; I'd say some program is what do they call it *wakelock* every now and then.

it's not just the apps that was just installed. It should include apps that are updated. I had this issue on SGS I when beautiful widget was having issues with updates causing the phone to use more battery power than usual
Morel likely to be a bad app, or a bad app setting causing the app not to close properly then drain power than the mere fact you restored it via titanium.

Turning off data packet doesn't allow any application going on line (unless you have your wifi on) and cannot download e-mails, synchronize anything, etc..
This saves your battery a lot.

Yes, that is also what I suspect. It is just to find out what which application / settings this cause.

Of course the updates are included. There should be an app/good optimized app which will allow us to close the apps and thus Auto Sync and Background Data to off when we are not using them, especially at bed time. The in built task manager's RAM Clearance function is crap and frankly I haven't found an app which will optimize the RAM without force losing the apps/widgets. Tried 'Gemini App' but I doubt! This 'Sync' stuff is the main responsible part of high battery drain.

If i can Root my 9005 - i intend to use Greenify,, as my battery is very poor (stock i'm lucky if i get 8-9 hours light/moderate use)
Is it a rated app,, can i expect big battery gains?
Thanks.
Depends which apps you have installed and how you use them. For example facebook drains much battery so you coukd greenify the app but if you do so you wont recive notifications anymore from it aslong you arent actively using the app.
In other words it prevents apps from wacking up.
As someone who already always manually force-closed all running apps, all I noticed was an increase in free time, as greenify is faster at it.
I didnt notice any increase in battery life.
If you don't manually force-close your apps, it'll probably have a bigger impact.

It seems to help mine. I run it with the Xposed Module that adds features that still preserve the notifications from Facebook, etc. I also have it set to boost mode for it to work faster.
I also haven't noticed much of an improvement. Many people swear it's a miracle app, for me it only turns off notifications.
True battery saver: green power payed version (on Google play). Set the phone to sync once at 4h and turn off wifi and mobile data on screen off. Awesome app, I tell you.

I do all that myself manually.... Sync always off and I turn Wifi or mobile data on when I need it, and turn it off when I'm done.
Cheaper than buying an app, too.
The real saver for me has been LUX. With our climate and the time I spend indoors, a brightness between -20% and 4% is more than sufficient. Now THAT saves battery! With brightness at 4, I loose 1% per 15 minutes whilst browsing! With it at 50, 1% per 5 minutes. At 100%, 1% per 90 seconds.
And when i use it in the dark, - 70%. I barely lose any charge at all whilst being an insomniac. It's been 20 minutes, still on 55% charge, which it also was 20 minutes ago. WiFi on, eWeatherHD update on, Tapatalk, Facebook and Firefox in use.
(if websites used less of that eyesore white, it'd save even more.)

I would suggest to remove some bloatware comes with the ROM / firmware itself.
It safes much battery though.
As well as turn on location, and on it when you want to use it.
And I freeze some apps which is running in background (which greenify can't detect it), which I don't use it as well.
and change to a good kernel.
it will really have a good deep sleep, never up if I never wake it up.
the apps running in background is only messenger apps like whatsapp, viber, and that kind of stuff. I never freeze this one and never put it on greenify as well.
So far so good.

I might look into that app. I go with the "free" lol DIY manual turn data/wifi off thing too, but sometimes I forget and I see wifi on when I had turned it off or so I thought. some apps are worth the couple dollars or so and I might very well get this one. Thanks for the tip on it. I like too that it automatically turns on wifi or data such as when you go to read an email or something.
You can also give these a try:
- Deep Sleep Battery Saver
- Juice Defender
- Tasker (You can configure it to auomate nearly anything, from 'turn on wifi at this and this gps location' to 'shut up completely between 2200 and 0800'. Does a lot of non-battery related things too, like launch a specific app when plugging in headset, or automatically move photo's from internal to SD.)

I'm pretty sure that I don't have this issue. Yes, the percentage in GSam maybe high, but I don't believe this reflects what is happening.
First of all - I don't have bad battery life. Usually my over night drain is less than 1%/1h.
Second - the issue appears sporadically.
Third - in the provided thread I don't see the issue appearing in stock battery monitor, while mine appear.
At last - my battery drains faster only while the issue is present and before I restart. After that it is back to normal ...
@Spo0f
Just some suggestions maybe you're using 3g I always have that turned off and switch it on when I use it my guess is that some apps are causing your drain after a call maybe like you said if you're not fimiliar with greenify I suggest you use it to stop all those apps and system apps also uninstall all those bloatware you don't need or at least freeze them if you don't mind lower the resolution to 1080p with nomone app use power save or disable dvfs and use an app to lower and raise the CPU to save juice when not needed....
Thanks for the suggestions, but as I said - this problem appear sporadically - home when using WiFi as well as outside when using 3G.

My overnight drain was also very low, but that was because the faulty device on the network was asleep at night too (my desktop).
If you're not rooted, use the PC version of Wakelock Detector at the end of your day and post screenshots of your highest drainers for the various categories. In my case, the device was being woken up by something on the network and it showed.
Bear in mind that actively downloading something in the time period will also raise wifi power used but more stats will help.
The fact that you're still experiencing a lot of drain even when outside suggests it might be a rogue app
One phone call today and after it the phone stayed awake.
Because I had issue with the PC WLD the screen shots are from 11 minutes after one of the disconnects. The device was awake all of them.

I also checked out my battery behaviour this night and was very disappointed. Although my phone was in flight mode and every peripherals and services shut down, today morning my phone was crying for energy. So I made a quick investigation in my power diagram and found out, that "Android OS" requested a wakelock during the whole power-on time. So I installed "CPU Spy" to check in which states the phone was really over the whole charging period. I couldn't believe my eyes. Although the kernel should do it's job good, cause most of the CPU times are in lower freqeuncy states, the deep sleep mode was never activated.
Therefore I installed an app called "Wakelock Detector" to check out which apps could cause that. I found out, that S Health had a big amount of wakelocks and also active-time, so the first thing was to disable S Health. After some minutes I checked back, but nevertheless still no deep sleep time in "CPU Spy".
So I searched around and found another one arguing about the wakelocks and that they could be the products of some programming issues concerning WiFi. The should be gone, after turning off WiFi and rebooting yout phone. And it seems that he was right. I waited some time and hooray, "CPU Spy" listed the phone state "Deep Sleep" the first time as an active state and also with the major active-time. So at least that was some step ahead. (I have to remark, that S Health was already unfrozen at this time, so S Health should not be responsible in any way.)
The next step was to reactivate WiFi, leave it on and set the phone on standby. After some time I checked back again the phone showed even more deep sleep time. So that was an improvement. I reactivated everything and waited some time... Deep Sleep all over the time. Can't figure out for now, if it was S Health, WiFi, or anything else that caused the wakelock for sure. At least the reboot helped. I'll check that out on a long-term test, maybe I get some further conclusions.
