I get always too much battery drain during night - Galaxy S III Q&A, Help & Troubleshooting

i like to keep my gs3 connected to wifi and muted while i'm sleeping but when i wake up i always get 8-10% battery drain (in 8 hours app), i come from a motorola atrix which in the same conditions i get no more than 2% drain over night.
i've tried many roms (omega, foxhound, ultimarom...), many kernels (stock, galaxsih, siyah, phenomenal medium and extreme...), and also some basebands (modem, radio) but i keep sticking with the XXLH1 'cause i get less drain with this one. but in any combination i always get 8-10% battery drain during night.
i've seen some of you say that you get 2-4% drain in the same context so i would like to know what am i doing wrong :/

im using the leaked stock 4.1.2 there now, and i had 3% drain in 11hrs between overnight and not using it this am.
seems v good for battery life so far. i know your pain though. its non usage time i want to be high batterylife. id expect 2-3 days from the phone when not playing games etc... im hoping this is gonna fix that now. most reports are good about battery so heres hoping.
in a few days will know more

How is it sleeping overnight? check settings > battery and check how much it's awake when the screen is off, then check better battery stats to see what is waking it up, I would probably say you have too much synced.

---

you're right, i have too much synced, 3 google accounts, plus facebook, twitter, whatsapp, skype and others but those are the same settings i had on my old motorola atrix and even there i got 1-2% drain, although i was on gingerbread.
i will install some battery stats application to see in details whats draining it so much, 'cause under settings it only says that idle and standby time are the draining reasons.
gonna try the leaked 4.1.2 to see if i get better results, thanks!.

Better battery stats is the best, but that is a lot to sync, I would imagine it's not sleeping well because whenever an app decides to sync it will wake the phone up, and let's not forget the S3 has a 1.4GHz quad core CPU, if it wakes and uses all cores it will drain the battery faster than a single or dual core CPU. I notice the Atrix has a 1GHz dual core, so you should expect a lot more drain especially with that much synced, honestly you shouldn't need Skype syncing unless you always want your skype contacts to be up to date in the contacts app, and Twitter just syncs to pull the latest tweets through, you can just do that manually every time you open the app.

Before 4.1.1 I got 9 hours 99% overnight no 3g or Internet, now it's 90%

does that mean that jelly bean is making you experience worse battery life?.
maybe it's because the atrix has 2 cores but if the gs3 uses all 4 cores to fetch or sync some data, that would mean it's not very well optimized for simple tasks, thanks anyway i'll try better battery stats

Android doesn't fully support multi-core CPUs yet, which is the main problem, all you can try if you need all the apps syncing is download a custom kernel and change the CPU governor this will change how the system uses the CPU and it can help.

Well for starters, Google Now should be disabled if you are concerned about battery life. Also check for and disable latitude and location reported from maps (they are getting activated by google now) Even if data/sync/gps are off google now constantly polling for updates thus draining battery.

With my HD2 running GB/Froyo for over 2 years, and methodical testing to achieve the lowest battery drain in standby (testing for 8hrs at night) the best I could do in AP mode was .35% per hour which is less than 3% over 8hrs.
I have owned and tested my S3 for 4 months and usually get 1% per hr and in AP mode....I get similar to the HD2 above at .35% per hour but I haven't tested to crazily.
I find it hard to believe and would love to be convinced, that any S3 owner can get less than 3% per hour drain without going into AP mode. Please prove me wrong and state your methods for all to learn.
Finally, I do not find the battery drain to be Linear. I am guessing that a battery charged to 100% sometimes may actually be a bit stronger than 100%. So doing a random single test may result in low drain numbers but that may be misleading. That same test performed at 20% level, may yield worse results if in fact my theory that the battery does not drain linearly...is true. But for consistency, I always perform the test at 100% battery and let it sit in the charger for an extra 2hrs before unplugging it. This way, at least the test is more consistent and more directly comparable.
I now have Green Power app installed and it is able to automatically turn off wifi/data in standby under conditions set by me, the user. I am performing some nightly drain tests. I would be thrilled if I could get between .35-.75% per hour. My first 2 nightly tests failed thanks to Slacker Radio....which held a Wakelock even though I bloody killed it!

I think this could be due to fast dormacy
http://www.androidnz.net/2012/06/at-your-own-risk-how-to-disable-fast.html?m=1 there is an app to disable this.
Read this link first though

A bit off topic but just reminds me of my old Nokia N95 because whenever I was in a network dead spot or just have no signal for whatever reason (Gif fgaff) the battery would completely run dry within maybe 6 hours, and you'd think because it has no signal it should last longer than the few days standby I normally got.
And I've never had a SIM in any of my Android phones that lost service for long so has anyone seen this happen on an Android or is it just a Symbian thing?

When a phone has no signal it has to scan all frequencies for a signal, this constant switching of frequencies drains a lot of battery, it also increases the power to the mobile networks chip to try to pick up even a weak signal, which also drains the battery faster, it happens on all phones.

Which I am running but 3% over 11 hours?
Any e-mail accouunts? What do you have enabled/disabled? What is syncing?
The best I have ever managed was about 1%per hour and that was with everything off apart from the cell.

Read the link I posted above about fast dormacy and if this is your problem then get the app fast dormacy from play store
If you're worried about wifi while sleeping also have sync turned off and location in settings and disable notifications from play store and disable notifications from apps also

Will give it a try but I have never seen it show up in BBS in the past hence never tried it (I was aware of it) and as far as I am aware O2 (UK) does support Fast Dormancy.
It is not that I an dubious about the 3% drop over 11 hours I just want to get to the same level!
EDIT: To get the 3% drop do you disable everything you mention above? I use Tasker to disable everything including sync, wifi etc...except the cell. But I do not disable play store notifications seperately.

This is what I have come to expect. 1% per hour is reasonable and typical. 3% over 11hrs...hmmm...I don't believe it.

I have messed with this before without positive results. But anyway, since it seems like you have it working...what is your typical % drain over 8hrs?

I usually turn mine off overnight but if I do want it left on I turn my location settings off and everything that requires wifi and don't lose much.
I'd suggest trying better battery stats from play store then after leaving your phone off overnight dump your results (in settings) and then go here http://forum.xda-developers.com/showthread.php?t=1179809 to ask about your results
