Do you have wifi set to stay on or off during sleep? I notice it takes a good few seconds to reconnect to wifi upon wake. Does data also stay on while the phone is asleep? In that case will keeping wifi on during sleep save more battery compared to just data alone? Thoughts?
I don't know how to override this without tasker or juice defender

Out of curiousity, which scenario would waste less battery?
Scenario 1
While at home leave wifi on and set wifi sleep status to never
Scenario 2
While at home leave wifi off and let phone idle on 3g, only turn on wifi when doing something data intensive and then turning off wifi as soon as I'm done.
What do u guys think?
Depending on your 3g signal at home. If its a poor signal it would draw a whole lot of battery juice

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
Recently I had started to lose wifi connection randomly, even when my tab was a foot away from my router. It was default 'never'. I switched to 'when screen turns off'. For the last 24 hours I did not lose connection. Shouldn't it be the reverse? I mean the screen turns off and wifi not.

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.
