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.

Wifi Sleep when locked not working
Hello, I have a problem, my wifi sleep policy is turned on to "when screen turns off" but when my phone is locked, the wifi is still on! I just pressed the lock button after 5-10 mins but the wifi is still on.
How long does it take for you for the wifi to turn off?
Any suggestions?

Not a suggestion as such but I'm reading that using the wifi sleep policy is detrimental to the battery life. Can't confirm as I'm still experimenting.
Yeah battery life is destroyed if you use WiFi sleep policy. Set it to never for best battery life. It's counter intuitive.
But to answer your question, I think it takes closer to half hour for sleep policy to kick in. You would notice WiFi off if you woke up in the morning etc or after long periods like hours of inactivity.

I'm having the opposite issue. As soon as my screen goes off I lose WiFi connectivity and get disconnected on adbWireless which is a huge pain for me when I'm developing... Maybe I'll enable sleep policy and see if that fixes my issue! Lol! I'm on stock 2.3.1

There's an option in Settings>Application Settings>Development to not turn the screen off when charging, that should solve your adbWireless problem so long as your phone is charging.

this is exactly how it works on the Galaxy S
there is an option in settings to keep WiFi on when the screen is Off in the SGS
but not sure if the NS has the same option (still waiting for my phone to arrive)

That's only if I'm doing adb over USB. I hate wires
I went to my wifi setting to make my wifi sleep once my screen shuts off but the setting doesn't stay. Is there a fix to this by any chance? Want my wifi to always sleep when my screen shuts off......

What do you mean it doesn't stay, it changes the setting to something else? When you have wifi set to sleep on screen off, it doesn't sleep immediately once the screen goes off, it takes awhile. I use "sleep when screen off" and I get great battery life.
Wait so is it good that my wifi turns off when my phone sleeps or not?

it depends on what you want
if you want to maintain connectivity then it's no good
if you want to save power, then it is good

Once I turn my screen off than turn it back on after a while my setting goes back to never even after I change the setting to shut wifi off once I shut off screen. Weird bit it does. I read in another forum that it saves battery but my setting keep changing back.

I've the same issue. I've try various app from the market for fix that, but all is the same. It's a hardware problem? The router will can cause this problem?
Thanks
Not sure if this is just a CM7 (#21 nightly) problem but I have the wifi sleep policy set to "when screen turns off". And yet it never seems to sleep. Does this happen for everyone?
EDIT: If this is due to some rogue app keeping the wifi alive, how do I go about tracking it down? I take it there would be a log somewhere?
Ahh, that policy still has a time out of 15 minutes or so after the screen turns off. Is there any way of changing this delay?

If i sleep the device overnight I lose about 10-15% battery. Wifi on, bluetooth off. my girlfriends ipad 2 only loses about 1-2% with the exact same settings. anyone know whats up? I don't own a dock.
stock 3.1, no root.
How about other options? How often do TF synchronize with Google (Gmail, maybe Google+ etc.) and other services.
Define "wifi on." What is the sleep policy for wifi?
Wifi policy is set to always on, which seems to be the same on the ipad. I have never turned on the ipad and had the wifi off, and it gets push notifications while asleep, which I want. And yes it is syncing to multiple services, but again ipad-esque settings.

My WiFi Policy is set to When Screen Turns off and I get notifications when tablet is off. Disable Syncing to Picasa, there's a bug with it and causes problems. Disable syncs for things you don't need.
Find a battery logging app and tell me whats the highest amt of battery usage per app?
Just checked, wifi is like 90% of the usage, so ill switch to screen off. Bet that fixes it.
Won't this affect apps like groove IP where it needs to be online to receive calls?

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?

Lately my battery just drops every 5 minutes. The phone is new. So I decided to try something. I turned my wife off last night and my battery only dropped one percent. So it seems wifi is using resources. Is there anything I can do to solve this? I am using a stock untouched phone.
P. S how come the Sub-Forum section is so cluttered and not alphabetical order? Finding the phones correct forum is a real pita.
I suggest to download Wifi traffic monitor app like this one https://play.google.com/store/apps/details?id=vn.wada.trafmeter or anything similar, to see what app is using wifi the most. You also can save battery by set wifi to never scan and never wake when screen is off. This will prevent any apps from using wifi while your screen is turnoff.

OK so my top app is chrome/Google. That doesn't make sense.... Because the phone drains fast when screen is off and wifi is on. I don't have unlimited data so I always keep that one off.

You need to set wifi "Keep Wi-Fi on during sleep" to NEVER and "Always allow scanning" unchecked.
