ICS Wifi stays on while on sleep

Hi guy, my wifi won't turn off when my Xoom is on sleep. I have set the settings of 'keep wifi on during sleep' both to 'NEVER' and 'ONLY WHEN PLUGGED' but nothing happens. Wifi stays on and keeps draining my battery life. I am running rooted with the latest version of nightly 62 and I've been having this issue since 55. I have reinstalled, flashed, factory reset, wiped my Xoom.
Is anyone else having this issue? What should I do?

From my experience, wifi stays on for a little while longer after device sleeps. However, some apps in background may trigger wifi back on again. So I turn off wifi when i go to bed. Actually i notice wifi itself will not drain much battery, 1-2% for 10hr. It's the host apps sucking the juice.
I am not an expert though.

OK i've also checked it out and as you said wifi turns off after some time. My main problem now is that my battery life won't last more than 3-4 hours on wifi.
I have posted my battery stats with use of web browsing and watching pictures on gallery...

What do you mean "no more than 3-4 hours"? In your battery chart, you can get more than that even starting from 75% battery.

What I wanted to say is that I think my battery won't last more than 4 hours with wifi on and some serious usage.. from my stats as I can see I've been using it 5 hours but I only had screen on and browsing the web. I think there will be a huge difference if I am watching a movie or playing a game.. I don't have the time to check it now but I will post my results in some days..
According to my previous battery graph do you see any problem or something less from what your Xoom battery holds? Does this battery drain seems normal to you?

I think you'll find it will stay on for about 15 minutes. There is some setting in a system database (using a sqlite editor) that can be changed to bring this down. I doubt Wifi is what's draining your battery. Are you synching email via activesync or running other stuff in the background?

I am only using my yahoo mail from the EMail app. I don't know if it uses activesync. I have set it to check emails every 30minutes.

wifi not turning off
Edit: I found the wifi sleep option in ICS. Google sure did a great job of hiding it. See attached picture for anyone else having wifi staying on during sleep issues.

So there are three options
Keep WiFi on during sleep
1) Always
2) Only when plugged in
3) Never
What option to set if i want Wifi to turn of after some time of when phone sleeps. Previously i had set the option to 15 minutes but that option is not available in ICS and i m having a hard time understanding how these options work on my sensation.
Can anyone explain what each of these options do ?

My guess:
1) Always: WIFI always on no matter awake or asleep
2) Only when plugged in: WIFI always on only when plugged to power
3) Never: WIFI will be off if asleep (my current setting)

That was it

Thanks, I had not seen the option to turn wifi off during sleep.

Bear in mind that (irritatingly) applications can seemingly change this setting.

For an app to change wifi sleep policy, it needs the WRITE_SETTINGS permission.

[Q] [ICS] Disable wifi when screen goes off ?

Hi everyone
I just flashed Android Revolution ICS Rom and I'm quite happy with that so far ! The only thing I cannot find is how to automatically disable the wifi antenna when the screen goes off...
Any help would be much appreciated

You can try in wifi setting and set wifi sleep policy to "screen off" out you can get Auto Airport Mode by Dan

Well I just took a look. Guess they changed it a round a little
In Settings under the WiFi, click on More and there's an "Airplane Mode" try that.
Or try Auto Airplane Mode (this is what I use and it work great)

hit menu (3 dots in top right) when you are in the wifi menu hit andvanced then hit "Keep wifi on during sleep" and change to only when plugged in or never

Wow... wouldn't have found it by myself
Thanks a lot !

I'm noticing the native setting for disableing wifi when sleeping is working poorly. It takes a while to turn it off and then when it restarts the service does not seminar to be able to obtain the IP address and I have to manually turn wifi off and then on again for it to obtain an address. Very strange because the auto airplane app has no such issues.

I have just found out that:
(under GB) "Advanced > Wifi Sleep Policy > when screen turns off"
is NOT the same as
(under ICS) "Advanced > Keep Wi-fi on during sleep > never (increase data usage)"
It is supposedly to be the same thing but it is not.
As osho741 observed, it takes a very long time to turn off and most of the time it just does not.
I think this is one of ICS bug.

It does turn off fine here after around 10 minutes but it takes at least 30 seconds to activate and connect.

Is there any specific reason youd want to turn off the wifi during sleep? In my experience it doesnt drain enough battery to bother turning it off.
In my case with wifi on and a few apps running that uses wifi all the time, the tablet drains around 15-20% over 12h while sleeping.
That gives at least 2.5 days batterylife if you keep it sleeping... I cant imagine you would have to have it turned on (sleeping) longer than that. In that case you could just shut it down completely when youre not using it

you should give juice defender a try. it revolves around battery optimization, but it isn't a task killer, it just lets you make whatever setting you want concerning turning off services like wifi, bluetooth, etc.. its highly customizable, so you can set it to turn the wifi off entirely while its asleep, or to keep it off, while turning on in whatever time increment you set, long enough.
i have mine set so that the wifi turns off and stays off entirely when its in sleep mode, but if i have a online radio app like pandora or 8tracks running, then they override the sleep settings, and keep the wifi on when the screen is off.or, when i use certain apps that don't need internet to run, like kindle or certain games, the wifi automatically turns off and remains off until i close the apps.
i really like it and i think its made a huge difference in battery. Before if used it, my transformer would drain 15-20% percent overnight with the wifi left on. now, it drains maybe 2-4%.

Turning off wifi during sleep makes a huge difference.
It really saves a lot of battery for me.
And juice defender, while it might help, but on my phone, it causes a lot of wakelocks.
You can check this with bbs.

[Q] Service management (google maps)

I found that removing Google Maps has made battery life much much better but am sad that I don't have the app for when I actually want to use it. Is there any way to force the service to never run unless I have the app open?

The app doesn't use a noticeable amount of battery life for me.
Do you have GPS enabled in "Location" settings ? Also, go to Map app's settings and uncheck "report from this device" under it's "Location settings". See if that helps. I keep the network and wifi location reporting on, it doesn't seem to use much/any battery for me. I only turn GPS on when I am actually using it as such (like when I used the Navigation today).

I have turned off all location settings. For some reason it still sucks a massive amount of my battery. With maps installed my battery dies in 6 hours with very little usage. The last two days without it I've managed to make it 13 hours and still be at 50% by the time I plug it in at home. It took a ton of narrowing down the problem but maps is definitely it.
I'm running AOKP on my Galaxy S3 with the latest 4.1.2 gapps installed. Not sure if the rom would have anything to do with the way maps operates though.
Edit: I also have GPS turned off at all times until the app is running (tasker turns it on when I open certain apps).

Something is killing my battery - please advice

Hi guys,
since a few weeks it's the same sh*t with every Omni-Nightly and franco.Kernel.
Everything is working fine for 1-2 day.
But then the cpu usage increases (i don't see any reason) and won't go back to idle again.
I tried several cpu monitor apps but none is showing me which app is causing this issue.
Please help.
And please don't blame facebook.
My cpu behaves the same way even no facebook app is installed.
If you need further information please tell me.
Thanks a lot for your help!

go to the main phone settings, location, now press google location reporting.. turn off location reporting and location history. your location will still work without these. no go back to the location option, and turn the mode to battery saving.

i've got this issue since 1 or 2 weeks.
i can say for sure that it's not any location services fault.

i see google play services showed up on your battery stats. normally, you wont even see it there, but you are at 71% and so far its taking 6%. its not the location services per se, they work fine with those options disabled. but it is a well known battery drainer.

you're right that those services are draining the battery, but in an acceptable way.
when i don't have the isse with the increased cpu usage i've 4-5 hours sot @ 12 hours overall uptime.
so i guess in general everything is working fine on my device.
but i don't know what and why is causing the high cpu usage :crying:

I'm no good at understanding BBS stats, but what is daemonsu?
There seems to be something keeping your phone awake and attributing its drain to "Android OS" which could be many things, including Widgets.

I could help, but prefer gsam screenshots. Unfamiliar with BBS.
Also, for starters....and please trust me here...just turn location services completely off for one charge cycle and see what happens. Also, Google settings app....go into android device manager and uncheck both options.
See how your full charge goes like that. If its still bad...its an app doing the damage, or a very weak signal.
Try it, and it will narrow down the problem. ?

Option 1. go back to 100% stock Rom see if it behaves the same
option 2. hard reset your phone and check battery usage with no apps installed
option 3. put your phone on airplane mode and see if battery still drains the same way using wifi. Usually if I have bad reception my battery will drain like crazy. My personal experience using my Nexus 5 I can't tell how much my battery is going to last day by day sometimes I get over 12hrs other days I'm lucky if I get 8hrs.

Wifi draining battery??

I've only had my nexus for a week now and I'm trying to hunt down the reason I'm getting poor battery life. At first it was nlp wakelocks but that went away on its own somehow. Now its my wifi draining battery, in 8 hours of idle overnight it went from 100% to 79% and wifi was the top usage. I've never seen this before on any phone with any rom so I'm not sure what to do about it.

Hi,
Try Settings/Wi-Fi/Menu/Advanced/ and untick Scanning always available...

This is what I did to improve my battery:
1. Location Services : If you are not in a neighborhood with a lot of wifi spots you will most likely feel this draining your battery life. Under settings make sure that Location Services is set to battery saving and not High accuracy.
2. Widgets : Weather widgets, games eat battery by constantly fetching information . Check the settings for these widgets and make sure they are using wifi and not updating the weather information every 30 mins or so. I keep my settings to update weather information every hour to keep it reasonable. The Gmail widget sometimes eats your battery too. I removed the widget and used an icon in the dock at the bottom to check my email. Another thing I noticed was that some widgets are just more battery intensive than others. For example I found HD widgets consumed nearly twice as much battery as Chronus on the home screen but both displayed the same information.
3. Restart your phone : Sometimes residual processes from closed apps could cause issues. Restart your phone if you haven't done it in a while and it should clear up any unnecessary things.
4. Keep wifi on during sleep : I made sure my phone uses wifi even when its sleeping. 3g / 4g eats the battery like crazy if you turn off wifi when your phone sleeps. This should be a default setting as pointed out by some users. In my case it had been changed probably when I was tinkering with the phone. You can find this setting in the Settings -> Wifi -> advanced -> Keep wifi on during sleep.
You can also use apps like Greenify , Tasker , and Llama.
5. Don't use Automatic Brightness : Turns out if the sensors are constantly looking to adjust brightness it takes up more battery. I set my brightness at around 60% and it works just fine throughout the day.
6. Use wifi over 3G/4G/LTE if possible
7. Switch off wifi when using Data: Android doesnt switch off your WiFi when you use data because Google wants you to use it for Locations and help build their database of networks.Switch off WiFi completely when using data to save a good chunk of battery.
8. Turn off Vibration on touch : Typing uses quite a bit of battery over the course of a day. Try switching Vibration on touch off.
9. Use Franco Kernel: : This will require rooting your device however it makes it a lot more power efficient.
10. Turn down the Facebook refresh rate : Make sure it updates not very often( every 3-4 hours) or never. IMO your phone is better off without Facebook or any other battery hog social networking apps.
