I have noticed my battery losing about 8-10% when in deep sleep. It's set to keep the wifi connected constantly as default . Is it better to keep it on or off whilst the device is sleeping?

Off to save battery otherwise it keeps searching .

If your not to worried about getting messages early hours of the morning, just turn Wi-Fi off.

"Losing about 8-10%" over how long?
The problem with setting WiFi to sleep when the screen's off is that the phone will still try to auto-sync overnight, meaning that it will use mobile data instead. Ironically, that may use more battery life (and mobile data) than having WiFi on permanently. It doesn't drain that much power.
Additionally I don't think it will keep searching for other WiFi networks as long as it's connected to one already.

I think it`s high, i lose about 3-4 percent at night, about 7,5 hrs. Have wifi on and full sync. Maybe you ought to check if other apps are causing the drain. Install cpu spy from the market if your phone goes in deep sleep.

Been using s3 abt 2 weeks solid fone but i got one issue battery life on it sucks! funny thing when im using it for the web, video,etc the battery holds up pretty well but its the standby time thts killing it. I charge my fone full everynite wake up next morning and the battery's down to 56% jus on standby!! with nfc off s-voice off just wifi on. Am i only one experiencing this or is this normal?
you have something else going on i lose 2% overnight...try airplane mode see what happens
I think your charger may be broken lol. You charge it every night yet your phone is at 53% when you wake up? Anyway, assuming you sleep 8 hours and that your phone was at 100% that is less than 50% on 8 hours. You probably get 17 hours standby time, not the best but not the worst. Try airplane mode

think you are alone... Yesterday, beach day: From ten o clock with 100% brightness, about 40 minutes surfing with dolphin browser, total in amount 35 minutes facebook, 30 sms, 9 calls all about 2-6 minutes and some recording of the soccer game; the rest of the time the phone was on standby. Coming home with 80% left....
what says your battery settings? what stands by "battery in standby"? How much takes "android system", how many apps are listed in total? Do you have battery save mode on?=> Try to turn it off. Do you have auto brightness? Turn it off, set the display to 40-50% and make a widget on home with settings to 100% so you can read under heavy sun. You are outside the day?=> turn the wifi off....
Tell us more and post your results, the comment that your device is a bucket full of crap is bull**** because the S3 has one of the best battery and settings in smartphone business!...

My S3 depletes 1-2 % overnight.

no-one can give you a legit answer as you haven't bothered to tell us anything about what rom/kernel you are using, what you have installed, whether you have any syncs switched on..
why leave wifi on overnight? thats gives apps the chance to update in the background
have you looked at bbs stats?
fail thread imo
You sleep with your wifi on? what do you expect to happen? Also try rebooting before you go to bed.

now i would like to know how you get that because mine drops from 100% (99%) to 95% in just an hour on 3g but nothing else..
I think you have a defective battery. Mine just drains 2-3% in a 8-10 hour overnight standby.
I hate when people assume something sucks when it's their own doing that's causing the problem.

Stop using Wifi, do not leave it on. Wifi is the culprit.

I still suspect this may be router related though. When I had my crappy Netgear, I would get strange periods of battery drain on my SGS2 when WIFI was left on. That just about all disappeared once I upgraded to an Asus RT-N16 running Tomato, and now, I don't get any drain on my SGS3 as well when I leave WIFI (set to "Always On" under Advanced WIFI Settings) idling.

I too think it's router related. It can possibly be due to Wifi dual banding in some routers that support it. Faster internet with less battery life.
Hello. I picked up my s3 this morning after having charged that night. I unplugged it at about 1 in the morning, with airplane mode on, bluetooth off, and WiFi connected. When I woke up though at 10, the battery had dropped down to 80 percent while in standby, with no recent apps even running. I'm not sure if this is normal or if it's a battery problem but it's quite annoying, because it drained 20 percent in 9 hours of standby. Any help is appreciated.

I will drain the battery and charge to full again tonight. After I check it in the morning, I'll note what the battery stats say is draining it. I don't want to do it right now because it's been influenced by my usage today.

This looks similar to my problem, and happens only when connected to certain WIFI-networks.

The things that it's say are draining it according to the usage stats are: WiFi, android os, phone idle, and android system.

Hmm. This could be my problem, but I'd need to try out some other WiFi networks to make sure.

Maybe caused by ~LG8 OTA combined with dual-band WiFi network?
I posted this over in another forum, but copying here to see what you all think...
..............
I don't know this for a fact, but I've read some things that lead me to believe the issue may (again, not confirmed), MAY be related to the recent ~LG8 OTA push. The root (no pun intended) cause is related to how the SG3 interacts in 802.11n band Wi-Fi networks that utilize multi-band (i.e. 2.4Ghz combined and 5Ghz running simultaneously).
One of the "features" of ~LG8 was to remove Advanced options for Wi-Fi networks, switching the connectivity logic to "automatic." If a GS3 is in a multi-band 'n' Wi-Fi network, it MAY be switching back and forth between bands, thus chewing up battery without actually pulling any data.
This is unconfirmed, so don't shoot the messenger. Can any of you validate whether or not the Wi-Fi networks where you see excessive drain is indeed a multi-band 'n' network?

This sounds like it could be a possible cause. I'll have to try out some multi band n networks in the next few days or so and see if there's any effect.

might want to turn down the screen brightness to under 50% if it isn't already, and set the screen timeout to a lower setting, 30 seconds to a minute. other than that, disable all the bloatware and you should get at least 15-20 hours.
Check screen on time and write it here.

I am using app called deep sleep battery saver. It puts your phone in deep sleep whenever you are not using the phone. In whole night only 1% battery used. I get minimum of 1 and half day of battery backup.
I see mine only drains fast when i am using 3g data connection.

Battery issues are very hard to troubleshoot over a forum. Turn off anything you don't need, i.e. WiFi, GPS, Bluetooth, etc. Looks like your screen is sucking a good bit of battery. I use my phone as a WiFi hotspot at work and it gets me through the night. Not sure what your specific issue is. Try one of the battery saving apps.
Ever since I got my SGS3 last year, I noticed that WiFi would drain battery rather than save battery. For whatever reason I always got better battery life with WiFi off rather than on.
I noticed a lot more wake locks too. I don't know if it was because with a solid WiFi conneciton, apps tend to refresh a lot more than they normally do.
Enter the HTC One. I have noticed the same type of effects. I've only had it for 2 days but I am noticing better battery life without it.
So I want to collect some data using a poll. Do you get better battery life with it on or off?

It goes inactive, but it doesn't actually get 'turned off'. If I don't have it turned off, what happens is when my wifi goes to sleep then mobile data goes back on. I don't want that.
of course you get better battery with Wifi turned off. but doesn't Wifi consume less battery than cellular data? my balance is to keep Wifi on ANYTIME i'm in a trusted wireless network and manually toggle off cellular data when I'm using Wifi.
It burns battery when it isn't connected and on but I get better battery with it on and connected

So I've been enjoying my ultra for the last couple days. Battery seems great. But losing percentages of battery at standby caught my eye. My phone would die when I wouldn't even be using it. So yesterday I found the culprit. Mobile network on all the time kept draining it. I disabled it and enabled wifi at work and home and now the battery lasts for days. Just a quick tip.

In every phone that's the main reason for battery drain on standby.
You could set Stamina mode to disconnect some functions you don't use while the screen is off, and leave on just the one that are vital (for you).
Anyway, another reason could be the signal strength in your area: if it's not strong enough, the battery drains because your smartphone is constantly trying to get the best signal (between 2G, E, 3G, H and H+) for its connections, and that is VERY battery consuming.

And if you could install better battery stats, you could see that none of the app used mobile data...

I'm pretty sure my phone is using it. If I disabled it and it improved my battery life. Then I think it was working pretty hard even on idle or even off.

Where are you located? Big city? Small town? Do you have a strong signal all the time? It'll use way more battery if the signal is weak.

I got it when I am home. Poor H+ signal and 3G signal, so it always switch between H+/3G/E and it result in bigger battery drain. I go in the center and keep mobile data open and no problem.
