What is the purpose behind the wifi sleep policy. I flashed to gingeritis and it recommends setting the sleep to 15mins for battery life. It appears to go back to the 3G/4G radio when wifi goes to sleep which I thought was counter productive and wiFi was better for battery life. Can any explain this to me?
I can't say this works for everyone, but I have "enable always on mobile data" disabled, so when I don't use my phone for 10 minutes or so it disables mobile data. If I have the WiFi sleep period set to 15, then it will disable all data in 10-15 minutes. Very useful if you have extended periods of time where your phone remains off.

HTC supplies a data widget that I use every day while I am at work. Go to personalize, then browse all HTC widgets and the data widget I use is the Data Dashboard. Its 43/58 on my phone but mine might not be right on as I remove a few of the widgets.
While I am at work I just click the mobile setting on the widget to turn data off while still maintaining my voice connect so I can receive txt and phone calls.
As for the OP I keep my wifi set to never sleep no matter what rom I'm on. This way when I'm at home my phone doesn't have to look for the network its always connected to my wifi access point. I have always heard the same as the OP that having wifi on is much better than using the network as far as battery life is concerned.
Setting wifi sleep policy to never is best for battery life. Letting the phone switch back to 3g uses more battery than just letting it stay on wifi all the time.

I'm a truck driver and I'm a heavy user.
I did too before I made the changes below. These all work with the Stock Rom.
1. Installed No Lock (so that I don't have to swipe the screen to unlock, just push the power button)
2. Set screen to turn off in 30 seconds.
3. Installed Brightness Widget (allows changing the brightness from the home screen
4. Installed Screen Filter (lets me really darken my screen at night.
Try those and see how you do.
5. I then flashed the Infused Rom (I now get up to 10-14 hours)

Also, Turn off GPS and Wifi when you're not using them.
Battery
After much experimenting and monitoring of battery use I find that the biggest drain is the screen display, so go to settings-->display-->brightness and lower the screen brightness as low as you comfortably can. Also when you you are not using the phone make sure the screen is off, I have trained myself to automatically hit the power button every time I put down the phone. If you listen to music through your phone make sure the settings on your music players allow the phone to play when the screen is off and turn the screen off while it plays.
GPS also drains the battery, so I keep it turned off when I don't use the Nav. When I use the Nav I know the battery will drain at a rapid pace, nothing you can do there, even if I have the phone plugged in to car power while using Nav it still drains the battery! Drains slower than unplugged navigating but still drains.
If your watching videos then your S.O.L. there's really nothing you can do that will increase battery life enough to make a difference during video playback.
I get 10-12 hours with regular use and stock rom. Worst was 8 hours best was 24.
Thanks for all the advice this has really helped my battery

There was a recent post that showed a shortcut for changing the screen brightness from the homescreen without any additional software. First, turn off auto brightness. Second, tap and hold the menu bar at the top. Third, slide left to reduce the screen brightness and right to increase screen brightness.

It seems that Samsung ****ed up and included phone CPU/screen/etc usage when measuring battery charge current.
This means that the 600 mA stock battery charge current limit isn't just going to the battery, it's split between battery/screen/CPU. If screen/CPU/etc go above 600 mA (Navigation at full brightness seems to be the most common way), battery starts draining.
It also means that unless there's something I'm missing (which I could be since the MAX8998 datasheet is super-ultra-secret), our phone isn't going to be able to do proper charge termination - if the screen is on/CPU is running, it will cause a falsely high battery charge current reading, which will cause charging to fail to terminate.

look in about phone battery use to identify the biggest battery user, it should be the screen. anything else and there is a problem.
the cell standby may go high on froyo rom, turning on flight mode and turning it off will correct that, it's an android bug.
on gingerbread the android os or android system may hog battery occasionally. some think it is the wifi sleep policy but it pops up on me without setting the sleep policy. the fix for that is to pull the battery for a couple minutes and put it back in and restart the phone.
next manage the screen brightness
install a custom rom, there are issues with certain firmware keeping sensors active wen they shouldn't be.
turn off unneeded sync options (i find that auto fetching my email uses a lot especially with my gmail already set to sync),
use wifi when you use the internet if possible, turn it off when out and about.
monitor cpu useage of apps that are cached in the task manager
kill apps that use cpu
if needed turn the max cpu clock down to 800mhz
set "use wireless networks" for location when possible for general location (limited to city level at times)

Actually, high cell standby is OK if the phone is screen-off often.
Cell standby is always my top user - but my phone is sitting on my desk with the screen off frequently, in a location with weak signal. Weak signal makes cell standby usage go WAY up.

I use awesome off to turn my pad on and off so I don't have to use the power switch all the time. I always do this so I don't have to go through the whole boot up process when I want to use it. I noticed that when I wake up in the morning the pad is dead or almost dead. Is there a better way to put this to sleep at night? There is always so much stuff running that kills the battery. I read on here somewhere that someone was not even losing 1% by putting it in some deep sleep. Is there a mode for long time sleep that does not use battery or run any processes? But without shutting it down all the way.

Toasted Marshmellow?
Can't you just set the tablet to sleep in 5 or so minutes after being inactive?
You can have the tab cut wifi off in sleep also.
I don't do the wifi off in sleep tho...sometimes it doesn't reconnect after a wake up.
I don't know what awesome off is...I'll have to check that out.
My tab just goes into sleep after 10 minutes when I set it down.
The problem is awesome off. It won't let the pad sleep and is constantly checking for movement, light levels etc. Dump it and use the power button to turn it off and on.

I have Nook color power button donate that I got when I had my old rooted Nook color with flaky on off switch. It was in my google apps when I was loading apps on my infinity so I figured try it and see what happens lol It works remarkably well on my tab and does put it into deep sleep . See attached. I have not used my tablet much in last day but you can see that it does put it to sleep and turns wifi on and off and also reboots. Also BTW I then tried it on my rooted ICS leak Bionic and it gives reboot function instead of the long drawn out shut down then turn on process. It does not speed up any of these functions as far as rebooting.
Could be the "wifi location drain"-bug with google maps. From reading the forums it seems quite a few people have it without knowing it. You can of course disable wifi while sleeping, but this will not cure the main issue.
Turn the location settings on in google maps, then make sure that unneeded check boxes are disabled under location settings menu and you should be fine after that. The interesting part here is that google maps will drain the wifi even when the settings are not enabled, perhaps because you can't access the underlying menu without first enabling it. So only after you first enable this setting in maps will it work correctly.
Hopefully this helps, it did for me ..
Yoop,
I watched the awesome off YT video and it didn't look as though the tablet was being sent into full sleep.
I guess with it just grinding away essentially not shut down into a battery save mode it would die.
Doesn't the Tegra3 have a 5th core for minimum power processing or fast wake up?
I have my Tf700 rooted but locked. I have been trying to just put the tablet to sleep rather than shut off (long boot times). With the sreen off and using Auto Airplane Mode by Don, my tablet is draining by 15 percent overnight (9 hrs).:crying: I'm using Battery Stats Pro. It shows that 'Cell Standby' is using >90% battery.

"90%" Does not mean it drains 90% of your battery.
It means 90% of the current battery drainage belongs to that process. So 90% of the 15% battery drain comes from Cell Standby, the remaining 10% are other processes (usually Screen.). So something else is draining your processes.
Cell Standby is the same as Idle Processes on Windows: Nothing.
It should use about 1-3% per night even without 3rd party airplane mode. So, based on not using that, which of these do you have enabled:
WiFi (Especially the "Keep during sleep" setting. Even with WiFi toggled off, this keeps running undetected. Same goes for USB Ethernet.))"
GPS
Power saving, Balanced or Performance mode?
Power Saving in settings
Auto brightness
Location services (settings --> location services), any of the settings in this menu.
Ever used a USB Ethernet adapter?
Using any overlay apps? (handwriting, graphic effects, alarm etc?)
Does the tablet's location get very cold overnight? Lithium-Ion batteries hate the cold, drains them 10 times as fast.

Idle is called "Tablet idle" on my TF700. "Cell Standby" sounds like the connection to a mobile network, which should not even run on a wifi-only device.

This was my first idea as well -- your 700 doesn't even have a cell connection, so this is a strange entry. Try using BetterBatteryStats or something alike, because the standard Android report of battery consumption is notoriously vague, and most of the times downright incorrect.
This harkens back to my SGS2 tweaking days in which loads of users were clamoring for tweaks to get the Android System consumption down from 99% -- "it is killing my battery" -- even when they had less than 2% overall consumption overnight. LOLOLOL!
These are high-powered devices, people -- if you'd want two weeks of standby time, you should have hunted down an old Nokia Communicator.
I still find a 15% drop in 9h of stand by time a bit high. Mine is a lot less than that...

Hm. Regarding the USB Ethernet adapter: Did you ever set the option "Keep during sleep"?
Reason I ask is because the moment I turned this on, it started draining my tablet+dock in a day, even without the adapter. Turned keep during sleep off and it went back to 1% a day. Never showed up in any battery monitor.
jcp2, do you have the TF700KL model version??
I will plug the usb ethernet adapter back in when I get home and see if the option "keep during sleep" is checked.(I only used the usb adapter twice.) I have the TF700T model.
Update.... I docked the tablet and plugged in the usb ethernet adapter. "keep ethernet awake during sleep" was checked. I unchecked it. I will let it sleep overnight and check the battery usage in the morning.

Great news everyone! After following ShadowLea's advice about the unticking the USB Ethernet option for "Keep during sleep" (Which is only visible if you have the USB Ethernet adapter plugged in BTW) I am very happy to report that my tablet lost only 2-3% over a 9 hour period overnight. :victory: Thank you very much everyone, especially ShadowLea for the heads up! :highfive: :good:
Glad it's solved

Same problem here, except even more extreme. My battery dropped from ~90% Tab + ~30% Dock to 24% Tab and a dead dock overnight. The culprit for me also appears to be cell standby at 90% of usage.
I do not have the KL model and so there is no cell radio, and have never used a USB to Ethernet adapter (didn't know that I could, I might try it out now that I know).
Keep WiFi on set to never
GPS Off
Power Mode in Balanced
Power Saver enabled after 30%
Location & Google Search the only location service enabled
No overlay apps.
Kept inside at a reasonable temperature.
I'll try turning off the Location & Google Search, but anyone have other ideas?
EDIT: See screenshot http://db.tt/ph1d0FVT
I keep Airplane mode checked
GPS off
location settings all unchecked
under ASUS customized settings: check "mobile dock battery saving mode" and also check " disconnect network during sleep" , Uncheck "enable smart backlightlighter adjustment"
These settings cured my battery drain problem. Good Luck!
There is a known bug with Location Services that causes battery drain, as it keeps checking for a signal, even with WiFi and the app off. Turn it off

I can not tell, some of my Tasker stuff is about battery conservation (turns off mobile data and switches to 2G at home and work, switches to 3G and turns off the wifi outdoors, puts the phone to airplane between midnight and 5AM etc.) or messes up my battery stats (for example keeps the screen alive when USB debugging is connected) Of course it needs some juice, but it conserves me even more.
Mine takes about 15 seconds also
