Hello,
i have a galaxy s2 with checkrom revo4 snd kernel siyah 2.5.1. i am pretty satisfied with the battety except with wifi.
if i leave wifi on, my phone will run out of battery in 10-12 hours even with minimal use (screen on time is about 1 hour). that means the battery drains 7-8%/h when the phone sleeps.
i saw some people phone which lasts 30 hours with wifi all the time (not sure he is on an extended battery).
so i really want to know if this kind of draining is normal? if not is there anyway to diagnose the problem and fix it? thank you very much.
i attached a screencap of my battery usage.
Do you have a d link router?

Bottom line keeping your wi-fi on is going to drain your battery way faster. I'm not sure why you would need to keep it on for 10 hours.. even 30 hours.
Perhaps the stats you saw lasting that long had all other radios turned off? That is the only scenario I can see something like that working.

not always. If wifi is always on but not connected then it will be constantly scanning and draining battery. But if its connected, (i.e at home), then it can save you battery depending on how good your network reception is. I get poor reception at home from my network and so if i turn wifi off but leave the syncs on the battery is working hard to try pulling in enough signal to work. I leave wifi on and i lose virtually nothing overnight.
edit: just to add i use checkrom v4 too with speedmod 18 and dont have any issues
I've been having exactly the same problems with this ROM and pretty much any kernal. Haven't been able to find a cure.

There have been a few threads where users have had similar issues wifi draining battery and the d link routers causing this.
Do a search for them some users suggested updating the router firmware, another flashed dd-wrt and for them that stopped the drain.

I keep getting contradictory information. Some say that the Kernal affects wifi performance not the modem, others say its the modem that affects wifi.

There's no option to set it to turn off automatically when the screen's off on my phone in the WiFi sleep policy menu. An app called Tasker can do it though, as well as setting it to turn off all data when the screen is off, etc.
My fix with an updated DLink DIR-615: change WPA2 Protection from TKIP+AES to AES (TKIP only did not work with my i9100). In G Only it seemed draining even less (quick test), but I got this router for N+G and it seems working now.

My battery doesnt last at all with wifi. I can lose like 30% with it on overnight. Is this normal?

Turn off wifi and data. Then grab a metal coat hanger and prod it in the head phone socket in the top of the phone.
Really good signal and no no loss of battery at all.

Wifi alone will not cause a 30% drain, wifi uses less power than 3g so your problem lies somewhere else. Have you looked at better battery stats, sounds like you've got wake lock issues.

Sometimes i leave the phone turned on during the night and wifi enabled.. I lose not more than 5% ... so i think your problem is something else
How would one fix wake lock issues?

Search for BetterBatteryStats on here/Market & install it. Let it run for 8-10 hrs/overnight/whatever. Read the first 10/last 10 pages of the BetterBatteryStats thread on here so you can get an idea of what information/screenshots you'll need to post so the guys who regularly post to that thread can maybe help you identify/reduce/eliminate the wakelocks.
Wifi *can* drain loads. There's a bug that causes certain routers to keep the phone awake. My dlink dir 655 does this - kills battery in a couple of hours idle. My netgear doesn't...

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?

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.

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

Hi,
first sorry for my English, I'm sure I'll some mistakes.
Is it normal for my GS3 to scan for Wi-Fi networks every 5 seconds even when I'm connected to a strong home network?
I think it's drain my battery because I noticed when my WiFi is turned OFF I lose maybe few % of battery, but when WiFi is turned on I lose above 10% overnight.
It's really annoying and don't know what to do...
Home I'll get answer.
Thanks!

Sounds perfectly normal to me, your phone is updating the available wifi around you, mine does the same. Leaving wifi on will use more battery than with it off, obviously.

I agree with you, but WiFi shouldn't drain so much battery. For example, last night I slept around 6 hours, and battery goes from 99% to 92%. I think it's little to much.
Are you sure that on your galaxy s3 when you go in WiFi settings every 5,6 seconds device scanning for new wifi networks?
Yes its normal that it is scanning every 5 seconds.
Al my android devices do that.
