I've noticed my Transformer's battery being drained when closed (and docked), and every time I change the wifi disconnect policy to "When screen turns off", as soon as I exit the settings it goes back to never. Does anybody know how to keep it at "When screen turns off", or why it changes back (maybe an app)? If it is an app, I would love to see an update from Asus that established a hierarchy where user settings overruled apps.

It seems to be a bug. I have a similar problem. Though set to "never switch off WiFi" the connection is lost, when the screen is off for several minutes. Switching airplane mode on and off reconnects WiFi afterwards.
BTW, I use the TF without dock.
might not be the best sollution as it costs money, but I use the app "tasker"
I have set a rule, that 5min after the screen has turned off it turns WLAN and synchronisation off.
As soon as I have unlocked it it turns these back on.
Maybe the App JuiceDefender can do the same?

I can attest to juice defender working. Before I was getting a day idling, now I'm getting 2.5 days.

Guys
I have set my wifi sleep policy as 'when screen turns off'. However, on doing a packet capture on my wireless access point, I still see some data from the tablet. Also, emails to my tablet email address cause a lot more data and the tablet responds to pings too
Isn't the wifi sleep policy supposed to turn the wifi radio off?
Thanks in advance!
yes, it should but I think wifi is not shutting down immediately after screen off, only after a few minutes or so.
Yea I noticed the same thing... its killing my battery wish this worked properly

Found out that I need to disable Airsync to get wifi to stay asleep. My idle battery is 20% of what it was before since wifi would never sleep. Don't know if you have DoubleTwist airsync or not but I lose 5 - 6% per day now.

ah,where to disable Airsync?
thank you
Here is a question about Wifi sleep that seems pretty obvious to me, but in case I am wrong I will ask here.
You enable Wifi, which shuts off 3G (but keeps 1X active). Now Wifi goes to sleep (when the phone is in your pocket), and while Wifi is sleeping, someone sends you a GMail. I assume that you will NOT get any push notifications while Wifi is snoozing away???
You should have WiFi set to not sleep.

To expand on Beezer80's comment, you will have better battery life if you set your wifi sleep policy to never sleep. Your power is drained faster with repeated search and connect actions by your phone, so you'd be better off keeping the pipeline open all the time.
I've noticed if I leave wifi on overnight, it drains about 30% battery.
My wifi sleep policy is set to never. The only apps supposed to use network is autosync from Calendar, Evernote, Gmail, Google Voice.
I'm using Darkside CM7. Is this normal?

Im pretty sure it is. having your wifi on is just like constantly having 4g LTE on, except maybe not as bad. Your phone is constantly connecting to Wifi/ trying to find a Wifi signal, so even if you have wi-fi on, and your not connected to wifi atm, it will still drain battery. If your using wifi, turn your 4g off so it doesnt burn twice the amount of power. same thing vise versa.
Is there a way to let it activate autosync once every hour but have wifi turn off rest of the time to save battery? I don't have a data plan so I can only use wifi.

Hmmm, 30%? If you were using stock, that would be normal but you are using CM? Thats definetly weird, have you checked your OC settings, that might be it. Also, you might wanna try setCPU to underclock it, it really saves a bunch of battery.
Under CPU settings I have Governor: interactive, Minimum:245, Maximum 1024.
When I have wifi off, it only uses 1-2% battery when I wake up.
This is very annoying, I have spent the whole morning trying to find a solution for this issue. The battery runs out already fast as it is, and now the phone is not
Battery drained about 20% at night by itself. Currently draining about 1-2% per 5 minutes when idle. What do I do? I have looked on various different threads for a solution, but did not find anything to fix this issue.
How do I fix this?
Thanks, in advance.
Also some details.
I had my phone at home, I prefer the phone to use WiFi networks when syncing and updating, but to have phone turn them automatically off when not using them, that is when the phone is locked and not syncing and updating anything. But apparently it doesn't do that, it has WiFi on at all times for some reason. And I don't know if its related to WiFi, it doesn't appear to go to "deep sleep"

For me, it was the last Google Maps update. Try to disable "Reporting Location" and "Location History" under Location settings on Google Settings app(the one with the green icon). I had around 25% drain over night and half of it came from this.
Try it and see if this can help you.
:fingers-crossed:
Like above say, disable location, especially if you keep wifi on.
Leaving wifi on while sleeping itself is not good for our health anyway, so if you have data switch to 2G, its at least enough to keep internet messages coming while saving battery. And if its wifi wise, apply pm.sleep_mode=1 in your build.prop. AND, scroll up a little, wifi_supplicant_can_interval(something like that, from its SHOULD BE 15 change to 300-600).
Disable unused apps and use greenify.

Thank you for the answer, but sadly it didn't seem to do it. My WiFi is still always on, even though I have it set to turn off when phone is sleeping at WiFi advanced settings.
Although the phone entered deep sleep mode when I manually turned WiFi off, but I'm not sure if that was the case.

I understand, but I forgot to do so, I actually have an app that turns on air plane mode at certain time. But that still doesn't fix the issue that the phone doesn't enter sleep mode with WiFi on and doesn't turn it off, even though it's set to do so.
Also I did not quite understand what you were telling me there, as I got the phone last week and it's my first android phone. The app you suggested could cut it, but that means that whenever there will be an auto check for news sequence I will be downloading it with mobile data? Is there an app that could cause this?
I was about to update on this, but I just got notification about 4.3 update. :laugh:
I will update this post, if this problem still exists.
UPDATE : Of course, still the problem persists, Phone goes to sleep when I have Wi-Fi turned off. But when on, even though I have it set to turn off during sleep mode, it keeps the phone wake and drains the battery.

How is it related to my router exactly? My iPod disconnects from Wi-Fi no problem.
Thank you for trying though.
I had left my phone this night with Wi-Fi off, but mobile data and 3G was on, Lost 7% in 7Hours from 47%. Does this seem okay, or a little bit too much? By the time I answered 2 emails and made 1 short phonecall and checked on battery logs from 2 different apps, and changed my wallpaper, battery has dropped to 33%. I'm not proud.
The answer to your problem is JuiceDefender Ultimate, available from Play Store.

Unfortunately this is normal, the battery life is not the best feature of nexus 4. How many screen on time hours do you get averagely?
This fixed the Wifi always on issue for me.
Turn WiFi on: Settings, WiFi, Menu (3 dots upper right hand corner), advanced, uncheck scanning always on.
Hope this helps.
