I just discovered this "feature" this morning as well. -_-
Did u find how to fix this?
I love the feature where the A500's battery doesn't last overnight with the screen off. I didn't think I needed to charge it overnight since the battery was at 95% anyways, so I just set it on the table next to my bed and went to sleep. Woke up this morning and it wouldn't power on. Pretty cool. Wonder what is draining the battery? My DroidX can sit on the same table for almost a week w/o being charged.
I haven't seen it, then again I play music from getting into bed till I wake up so ill try leaving it to sleep and see what happens.

Me too
Same issue here.
i have not tried the trick that I just found that seems to extend the batery life....I put the tablet in "airplane mode" , enable the WiFi and the battery looks like it is draining alot slower. There is power being used for "cell standby" even though is a wifi only tablet
Same problem here with shutdown on charge. Right now it seems fairly consistent-
I'm experiencing them same thing when leaving asleep for extended periods. It first happened while I was charging... now it happened again when I left for dinner and came back. I don't see any setting options for that
Same here. Thought it was a "feature" to keep from using as much battery.

So shutting off notifications seems to stop the problem for me.. except that I don't get notifications At least it boots pretty fast
Lets run some tests, shall we?

I don't think they're shutting off, I think they're crashing/freezing during sleep and not rebooting.
This is speculation by me, and could be different for different people.
Finding the problem:
The test.
Night/Bedtime
This is an overnight/while you sleep test and requires about 2hrs. of your time beforehand. Record your figures if you can and post them for debunking. A couple hours before bed and while you use the tablet during the evening, charge it. After 100% and once it's off the charger please don't use it for anything. We want to simulate the sleep process for about 90m before bed. So if you use the tablet even for a quick web surf, plug it in and getting back to 100%. We're going to allow ~3% for errors anyway but we want to be as close to accurate as possible.
90m before you're ready for bed remove the charger. Don't use the tablet simply set the brightness to auto and take note of your battery level and the time. 60m in take a look at that battery charge again and record the time and charge level. 90m in is the last check and after this whether you go to bed or not please don't wake the tablet. Don't worry if it seems to wake and go back on it's own. That's inconsequential for this test. Just put it somewhere that no one will bother it and resist using it until you wake up. Please
Morning/Wake time
Wake it up.
1. Comes on? Record the charge level and time for posterity so we get an idea of idle drain here on the thread. Everyone gets different values. You'll have to run this test at another time as your shutdown/freeze hasn't been reproduced this time.
2. Doesn't come on? Try a power on press. Comes on? Same as 1. Record the charge level and time and post it here.
3. Doesn't come on? Try a power on press. Doesn't come on? Plug it in and power it on. Now do the same as 2. Record the charge level and time and post it here.
I hypothesize a few different scenarios the summary of which is that I don't think they're shutting down, but this is mostly based on the assumption that the batteries are being charged while the unit is frozen. If they do not charge then my entire test would have to be re-designed. I surmise they freeze and don't restart so they either run out of juice or they're actually frozen when you try to power them on and the long press is rebooting the unit, not powering it on. If I am right then we should see that the batteries are drained as if they have been on all night. This is going to be very imprecise, but my idea is that we'll take the charge % of your bedtime check which is a 60m mark check and just times that by the amt. of hours you were sleeping.
So if you were at 95% when you touched the tablet for the last time, this would mean a drain of ~5% give or take ~1% due to your use while checking, per hour. You take that and multiply it by how many hours you've slept and you'd get X x 5 = 40% which leaves the tablet with ~60% battery when you wake up, again give or take 3% for errors, syncing during the night etc.
If you're seeing a somewhat accurate numerical representation of this formula then it means the tab drained all night.
If you're seeing something way off like the tablet still having way more than it should then it means at some point in the night it really did shut down on its own.
People who are actually saying it shut off probably just reboot the tablet without realizing it as it was on the charger when it froze. Since a power off/reboot press of the power button is roughly the same length as a power on press, it's difficult to differentiate sometimes.
Solving the problem:
I have had this happen twice and it was while I left GPS on.
I haven't had an android cell phone yet that hasn't frozen or reboot itself when I left GPS on for extended periods (aka overnight) so the first time this happened I instantly knew to check and I purposely left it on the second time to reproduce and the second time, the tablet ended up rebooting not freezing. If you're not technical the easiest way to know if your tablet reboot during the night is to leave a web page or IM window on the screen or leave music playing.
You may want to skip the above "finding the problem" tests and attempt this "solving the problem" test. As I mentioned, this is all speculation so I'm just trying to get to the bottom of it and I'm sure we can as a grp.
Once you rule out hardware though, then it's a problem. So if it is indeed NOT the GPS then we're at the mercy of Acer and Google because otherwise there'd be just too many factors to track down.
I'm getting this and i'm loosing a ton of battery somewhere in the process too. I think the above poster is right.
I plug in tabby. go to bed. wake up to pee. see tabby is 100% battery. unplug and go back to bed. wake up to go to work and tabby is powered off completely and battery is anywhere between 85%-90% in a matter of 2-3 hours after being unplugged.
Its likely a rogue app I would get a program like advanced task killer watch it and see what apps are loading in background after you kill all apps.look for apps you installed.not so much the ones Acer put on your tab.
With Ti backup freeze the first one you think should not run give it a day.if that's not the issue keep going down the list.
Had a similar issue it was a app I got from amazon.that was So CALLED FREE.they are not so I uninstalled everything from amazon. No more battery drain.
SOME APPS do not fallow the drained android or social rules
Watching the apps to be sure nothing is running CPU cycles allow the time I loose about 2 to 3 % batter life over night with wifi set to stay awake.
This is ideally from 11 pm until around 10 am the fallowing day.
Yes I sleep in alot giggles
re-flashed with Taboonay v.2.0/Richardtrips v.3.3 Kernel and it fixed everything.

Dear customer,
We have received the RMA application form with the serial number: B5Oxxxxxx. The form has been rejected.
You have advised us of the below:
"Dock drain issue. Dock only to be returned to have issue fixed. Please advise if this is the case as I read elsewhere only the dock is required in order to resolve this."
Unfortunately nothing was mentioned on troubleshooting.
Therefore we have to advise you to attempt the below:
(1) Make sure your software is updated to 8.2.3.13 or later.
(2) Dock the Pad into the keyboard dock.
(3) Go to [Settings] and select [Screen]? [MobileDock Battery saving mode]
(4) Press power button on the Transformer Pad to make the unit go to sleep.
(5) With the option checked, if your unit does NOT wake up with the tap of a keyboard, the new battery saving mode is enabled and working.
(6) If your unit wakes up by a key press in both options (when the box is checked and unchecked), you have the earlier design.
(7) If #6 is the result and you also require the new feature, please resubmit the RMA application form on the link: http://uk.asus.com/rma
Best regards,
Asus UK

Well the problem with that RMA form is twofold. For one thing there is a 150 character limit and secondly if you enter any characters like ( or ! or url's it will reject the submission. It's complete crap! I wanted to point to their own url aknowledging the issue in the description but it won't even allow that. I already discussed the issue in my emails to them but the plebs who read the RMA are obviously not reading the support emails that go with it.
Terrible support.
BTW it meets the criteria of numbers 6 and 7. I tried quoting that but it would not accept the form with the ( and ) characters. I do not know if fixing that also fixes the battery drain issue also though.
(5) With the option checked, if your unit does NOT wake up with the tap of a keyboard, the new battery saving mode is enabled and working.
What's funny about that is that option does NOT work period, at least it doesn't for me, enabled or disabled I am able to wake mine up with any key press and there was a thread on this with others complaining awhile back of same issue.
So could this be causing the battery to drain too fast where both the dock and tab are not staying in sleep mode correctly?

I imagine it's possible, and honestly I haven't seen alot of people complain of that battery saving option not working, only once actually. I'm now curious how many of you also find when this is enabled it's no different than disabled, it still lets you hit any key to wake it? I did get an email back from Asus just this morning from when I complained to them about the battery drain and a couple others, I replied back to them pointing out this problem as well.
Enabled or disabled, it's the same for me. Keyboard will always wake the tablet up.
I've just test it, and even with the "power save" option check, the tablet wake up from sleep mode !
edit : Can this option be fixed sy software update ?
Ditto for me, the checkbox makes no difference.
Well they have sent an email now saying they will pick it up tomorrow for RMA. However they did not answer my question as to whether I had to send back both the tab and dock so I am going to just send the dock back and hope for the best. If they ask me for the tab I will have to think about it. If they return the dock with no repair done then no loss there either really (I do not use the dock that much to worry about it. I would rather it was fixed though just in case).

Checked here, as per directions, TF will not wake up by pressing any keys on dock/keyboard with battery save selected. It will wake up if battery save deselected.
TF and Dock both B6 models
3.1 Build 8.4.4.11
Well that seems to be VERY telling. The B60 models appear to have fixed that issue which most likely means the battery drain issue is also fixed on B60 models. I wonder if I can get away with just sending back the dock though. We shall see.
I got the same reply to my rma. My tablet does not wake up pressing a key with that option on. It's a b50k dock. Yesterday though the battery level dropped by 25% in 5 hours with the tablet docked and WiFi off...today only by 2% over the same length of time, and in both cases with the battery saving option on.

I believe there will be some users with dock labeled B60 that actually have a B50 functioning dock. We have consistent reports from a couple users of this problem.
But, this is likely more of a problem of ASUS quality control.
I have a B50K dock and the battery saving mode works. I have not used the dock yet enough to know if that will ultimately improve the battery life.
Have you tried to monitor the dock battery:
http://forum.xda-developers.com/showthread.php?t=1112391
undocked and redocked. Now the key presses on the dock doesn't turn on my transformer. But my battery still gets drained. I got a B40 dock and B40 tablet.
Nevermind. For some reason when powers plugged in to the dock keypresses on the dock doesn't wake it but does wake it when i'm not plugged in.

Were your tablet fully charged yesterday ...? 25% over 5 hours seems a bit much to me.

I don't think this is quality control issue,
from what I've gathered from the web and this forum,
it seems like there are 2 different kind of B50 out there,
the battery drain issue isn't really an "Issue",
I think they purposefully made some current go through the keyboard so the tablet is able to wake on key Press.
and maybe they change the design after people complain about the battery drain problem, so they change the design.
B40, B50, B60 doesn't mean anything, it just means the month the machine's manufactured...

That makes sense. B60 being June.
Just a crazy idea based on what I've been reading on the forums, and what Asus has said. If you have proof to prove me wrong, please provide it.
Asus said on facebook that they would be contacting people regarding the dock charging/drain problem. Asus just contacted a bunch of people about the MobileDock Battery savings mode. It is both a hardware fix (earlier versions of dock) an firmware update, which is exactly what people have been expecting to fix the dock drain issue.
Most B60 docks don't have the drain issue, from what I hear. They also can use the battery savings mode.
I've yet to see someone say they can use the battery savings mode and not have dock battery drain problems or vice versa. If I am wrong, please correct me.
My B60 dock can't use battery savings mode. When checked, tablet still wakes up from keyboard. I also have the dock drain problem.
The dock drain problem is related to a low power state for the dock, which is exactly what the MobileDock Battery savings mode is supposed to remove.
My guess is that the dock never exits the low power state. If the battery savings mode is used, the dock never enters the low power state, and thus the dock drain problem is fixed.
Maybe I'm crazy, but I don't think Asus is ever going to admit that there was a problem. They definitely don't want to issue a recall notice. Most people probably don't know they have battery drain issue, because you can not see the dock battery level on stock, without installing the dock battery app. I know I would have never noticed the battery drain problem until I went on a long trip, had I not found out about the battery app and the problem here on XDA.
However, Asus would do something like this MobileDock Battery savings mode fix, fixing the problem silently, and waiting for it to go away without making a fuss. Here is my proof, directly from the letter from Asus most of us got:
(7) If #6 is true and you also require the new feature, then please contact your local ASUS service center
I also think that the mystery dock firmware, which updates from 209 to 209, may play a part in it. People in the USA and Europe have been receiving this update. They also have MobileDock Battery savings mode working, and lower battery drain on the B60 docks. I've had 4 Chinese B60 docks, all of which had the exact same battery drain rate, MobileDock Battery savings mode didn't work, and in china we never got the mysterious dock update. I'm gong to flash my B60 TF101 to the WW firmware and see if I can get the mysterious update and get MobileDock Battery savings mode working.
If that doesn't work, I'm taking my TF101 to the Asus service center to get them to fix dock battery savings mode. I have a feeling it will also fix the dock drain.
UPDATE: I took my B60 tablet and dock to Asus service center, and was told specifically that fixing and enabling the MobileDock Battery saving mode would fix the dock battery drain problem. He also told me about which parts needed to be replaced and the software update. Will elaborate more when I have time.
i have a feeling that to test this energy saving mode, you have to wait a certain while before the dock actually goes into power saving.. when this mode enabled, i can wake my transformer instantly shortly after the screen went blank. however, if i wait several minutes i can only wake it by using the powerbutton. also when you close the unit, by putting the screen down on the dock, th screen goes dark immediately, and when opening it, also after an hour or so the screen goes on immediately, regardless of the powersaving mode. so the dock also has some kind of switch build in to sense the position of the tablet. so i think the powersaving mode actually works, but only kicks in after a while. i have b60 tablet and b70 dock, purchased yesterday seperately...
I originally thought the same thing. If you wait a while after putting the dock/tablet combo to sleep, when you wake up the tablet, it has to re-mount the external sd card on the dock. This would mean the the dock was effectively disconnected/powered off.
However, the instructions from Asus are:
(4) Press power button on the Transformer Pad to make the unit go to sleep.
(5) With the option checked, if your unit does NOT wake up with the tap of a keyboard, the new battery saving mode is enabled and working.
(6) With [MobileDock Battery saving mode] checked, if your unit still wakes up by a key press, you have the earlier design.
Since Asus provided these, I have to use it as my basis for testing.

I completely missed that! You have a B70 dock!?!?!?
It's pretty clear that the battery draining is directly related to the keyboard not powering off at all. The broken docks have no way to turn off the current to the keyboard, which is where the battery drain is going.

So the obvious question is: Do you have a dock battery drain issue? With the tablet powered off and connected to the dock, does your battery drain? You can use the dual battery widget to test.

i will tell you tommorrow, because both tablet and dock are almost empty, i'll charge them fully this night and will test it when i wake up. I leave the tablet powered off for two houres connected to the dock, is that enough to notice any drain?

Check the box it came in, because the serial number should be on the box.
You should have a peace of tape with s/n on the dock, at least it is on the new device. Also s/n is on the tf's box.

2-3 hours should be good. If it drops more than a percent, you have a dock drain. If it only drops one percent, might just be the battery going from 100% to 99%, they tend to do that really quickly.
this is weird because my tablet and dock are b50s and i have NOT gotten any updates, and my setup works as asus explains it should, ith it checked, the kb doesnt wake the tablet.
however, mine does suffer serious lag, when typingin web forums like this...
ok i tested my tablet/dock combo for battery drain. when fully charched, in normal standby mode, i loose 2% per hour. when completely turned off dock battery went from 96 to 95 in 2,5 houres.the 1% drop could be explained by powering op the tablet ofcourse. so i think i'm safe with my b70 dock
Where do we enable the battery saving mode???!

Sounds like you are good to go. I think the 2% per hour is standard for standby mode with MobileDock Battery saving mode disabled. That's what I usually get on my B60. You might want to check to see if MobileDock Battery saving mode is enabled. If it isn't, enabling it will extend your battery time, and you only lose the ability to wake the tablet via keyboard.

The following is a step-by-step guide on how to verify if your unit can support the new optional battery saving mode:
(1) Make sure your software is updated to 8.2.3.13 or later; and your mobile dock is updated to 0209. ([Setting]>[About Tablet]>[Build Number] & [Mobile Dock version])
(2) Dock the Pad into the keyboard dock.
(3) Go to [Settings] > [Screen] and select [MobileDock Battery saving mode]
(4) Press power button on the Transformer Pad to make the unit go to sleep.
(5) With the option checked, if your unit does NOT wake up with the tap of a keyboard, the new battery saving mode is enabled and working.
(6) With [MobileDock Battery saving mode] checked,iIf your unit still wakes up by a key press, you have the earlier design.

So to elaborate on my visit to the Asus service center. Also this conversation was in Chinese, so some details may be lost in translation and due to my poor chinese language skills.
I told him about the dock battery drain and non-functional MobileDock Battery saving mode on my B60 tablet & dock combo. I also showed him the letter from Kimi_Q in English. He was able to understand the important parts of it.
He verified what I told him on the TF101. He then went and read his Chinese version on the instructions regarding MobileDock Battery saving mode. He told me to fix it he would have to order parts to fix my TF101: one week for delivery, and 1 or 2 days to fix. Said he would call me when the parts came in and to bring back the dock.
Then he said (with a lot of gesturing to help with the language barrier) that fixing the MobileDock Battery saving mode would fix the dock drain as well.
I asked him about the parts. He said something about a part on each side of the dock's hinge, that feed electricity to the tablet. After looking at some pics on the inside of the dock, there is a cable running into the hinge on each side. So I think it these cables that need to be replaced. I asked about a firmware update. He said I already had the latest firmware (209), and that the fix was software related, not firmware.
I'm sure I could go back and ask some more specific questions, if people want all the little details. He seemed really eager to talk with me. Also there was were no other customers in the service center, which is quite common here.
The Asus customer service and repair center's in Xi'an are awesome. They usually test the computer right there on the spot, if not they get back to you in under 24 hours. Also, they will talk to you all day about your computer and problems with it. It is so much better than dealing service centers over the phone. As soon and I have a problem, I just drive down to the service center and they get right on it. Just awesome.
Oh, I also asked him about the mini HDMI-to-VGA adapters. He didn't know anything about them, so Asus must not be selling them yet.
link to what asus said on facebook?
My tf wakes from keyboard touch, but i have t battery saving mode on. dock is 50 version
I have also tested. gps off wifi off. battery save mode on.
completely charged. completely shutdown.
after one night of sleep. tablet 100% dock 81%. so there is definatelysomething wrong.
I didn't want to create another thread for this, but I couldn't find anything solidifying what exactly is going on with the dock and battery drain.
So apparently, according to asus, we should be able to enable a feature "MobileDock Battery Saving Mode" that is intended to fix the battery drain with the docks. If i'm not mistaken, when we enable this feature, the TF is only supposed to awaken from the press of the power button and not from just opening it or pressing a key. I have confirmed that mine does not do this. With the feature enabled, it still turns on whenever I open it or press a keyboard. This is were the confusion comes in (unless i'm wrong about everything else, then I'm just really completely oblivious), if my TF isn't doing what its supposed to in order to conserve battery life while in battery saving mode, then does that mean I am sol?
Is the only viable option to RMA it? (i'm well out of my return period)
If so, then does that mean that this is a hardware issue? or is there a possible software fix that may come along?
Also, one more thing, would something as simple as undocking the tablet when not in use remedy the issue? If so, then i'd much rather do that then go through the hassle of returning it and waiting god knows how long to get it back (although I do live in Texas and I heard there is a repair center down here) when the battery life is still relatively good.
Any updated info would be greatly appreciated. Again, sorry about creating yet another thread over the same beaten horse.
Thanks in advance.
Afaik if your tablet is waking up from a keyboard press with the option enabled you would have to RMA it if you would like the feature to "work."

I don't know where "if you open the lid and it turns on" got mixed up with the button press test. Asus never said anything about opening it and it shouldn't turn on. It turns back on because of the magnets.
Does yours pass the button test? If not, it will need to be RMA'ed or exchanged. (If you feel the need, don't fret, your dock is still perfectly good)
I have the battery drain problem. I am thinking about adding a physical on/off switch to the dock to disconnect the battery. Of course I would need to find a switch rated correctly for the power consumption of the dock and make sure what ever I do looks good.
My B70 wakes when I lift the lid up, but no battery drain. It was 100 when I went to bed and 100 when I woke up. No tablet or powercord on the dock.
Yes, the "MobileDock Battery Saving Mode" is the fix to the dock battery drain. If "MobileDock Battery Saving Mode" isn't working, you have to do a hardware upgrade via RMA. I have a B60 which is waiting on the parts.
The dock battery drain was caused by the dock having a low power state which never turned off. The "MobileDock Battery Saving Mode" turns off the low power state. I don't think it is anymore complicated than that. If you RMA, and don't turn on "MobileDock Battery Saving Mode", then you will probably still have the dock battery drain.
ok, thanks for clarifying that for me guys. My dock does need to be returned because it does turn on from a key press when battery saving mode is enabled, but I think i'm just gonna go ahead and keep it.
I undocked it last night and the dock only lost %1 battery in over 10 hours which is good enough for me. Ideally I don't wan to have to undock it as much, but it seems like a simple remedy to a over exaggerated problem.
thanks again guys.
My findings...in the main thread... http://forum.xda-developers.com/showthread.php?t=1112835&page=87
Prior to ICS my tf101 would last a good 3-4 days on a fully charged battery with my normal usage during the week. Yesterday I installed ICS went to sleep with just over 50%, it had suffered some heavy usage yesterday, and woke up to a completely flat and switched off tablet this morning. This is very unusual performance for my tab.
When I installed ICS I did a factory reset to clean up my tab so only have a pinch of the apps I had previously installed. One thing I did notice is on the battery tab of system settings the tablet was awake 100% of the time were traditionally it would only have a blue mark were it was in use on the awake line. Battery usage data is unavailable, too, so cant see what is causing tablet not to sleep.
Any suggestions?
I would wait until it settles a bit more, plus wait for a custom rom. It probably has some bug, seeing as it is the first ICS for our device.
I also notice some battery drain last week
on HC and ICS
right now i reverted back to honeycomb
ill update you later
if anything changes to me
MyZine Widget
Got rid of the MyZine widget and my tablet now goes to sleep in standby. I noticed, when browsing the running apps list, that the app kept 'restarting' so it could buggy or at the least was having a problem with my tab.
Prior to ICS my battery drain was crazy, especially if I leave wifi on. Not anymore, it's back to normal consumption like I had before the last HC firmware update.
I had the same problem this morning.
take cpu spy to have a look if the tablet goes into depp sleep.

i had to reboot and then everything was fine...
I've still got problems with my tab. Returned to it after a few hours non-use and it had shutdown itself. Battery Drain still seems an issue too. I'll install that app and see what it reports.
Check WiFi disconnection policy and if GPS is disbled.
Here I am trying to get answers to exactly the op's problem. Everything went smooth installing ics. Even wiped data.
Woke up this morning to a very dead battery. Went to sleep at 83%. Interestingly, the battery graph show nothing after about 80%. No indication on the graph of total discharge...and no app usage. Just straight from 80 to zero.
I can't determine if it's a hung app or what....I've installed almost nothing. And it looks like the tablet drained while it was OFF!

Sorry for the link....I could not get the damn picture posted for the life of me...despite 45 minutes worth of my time.
i also woke up to a dead battery this morning. it was 50%+ when i left it on standby, wifi & gps switched off. i would have expected minimal drain on HC.

Prior to ICS my tf101 would last a good 3-4 days on a fully charged battery with my normal usage during the week. Yesterday I installed ICS went to sleep with just over 50%, it had suffered some heavy usage yesterday, and woke up to a completely flat and switched off tablet this morning. This is very unusual performance for my tab.

Try this
Go to settings /WiFi /click three dots in upper right corner/Advanced/ uncheck keep wifi on during sleep.
go to recently used apps and close all ( swipe to right)
put tab to sleep for a while
Come back and turn on.
go to settings
battery
tap grey battery level graph to expand
check individual bars to see what was on and off.
Looks liks some apps are keepi9ng WiFi and GPS on and draining battery.
It would be really nice in future update to have a setting like below:
Setting
Sleep setting
On screen off close all apps except ( here you get to choose apps to leave open)
I'm glad I am not the only one with battery drain issues. I thought I was doing something wrong.
Several days ago I charged my dock and tablet fully. I then turned off the tablet, closed the lid and didn't use it for a few days, when I went to run it again it was totally dead. I would have expected it to at least hold something of a charge in a completely off state.
Yesterday I left the tablet and dock on but just turned the screen off and again this morning had a drained dock.
Just seems like no matter how I try to settle on a way I still see more of a drain than I would have expected.

I will have to take a look at that setting myself and see what is up with it.
Yes, it would nice to have a sleep setting button for some helpful settings.
Have there been any firmware updates for the dock itself, or is that not possible?
I'm having the same issue dock was at 80% last night get up this morning and it's at 6%. I set wifi to off during sleep to see if that helps any.

Have to close apps that are keeping stuff on. Look at permissions. More and more are adding "prevent "Function X off during sleep."
As soon as I got the update installed I turned GPS off and set WiFi to never sleep, woke up this morning to only 4% battery drain. The tablet went 12 hours and went from 40% to 36%, i also had apps open...
apps open: engadget, camera, browser, gmail, market and settings..
no battery drain yet, updated yesterday and only 5% drain during the night with apps open
Help!
Same problem here. I noticed high battery drain yesterday and didn't think to leave it plugged in.
This morning, it wouldn't turn back on! I've left it plugged in in case the battery drained too far and will try to turn it on later on.
With HC, the power button was buggy (had to press really hard) and seemed that that went away with ICS (well except for now). Don't know if this is related.
Same issues with me. Except my tablet won't wake up when I push the power button. I have to hold and reset it. Here is the kicker: I will get a 20% power drain over 9 hours on top of it. So not only does my tablet not turn on after it being asleep, but I get a power drain as well!
My Settings: Stock ICS off a completely reformatted device, Keep Wi-Fi on only when plugged in, screen timeout is 1 minute and MobileDock Battery Saving mode is on. My battery usage indicator does not work... I have to get the very basic info from my battery widget.
Very disappointed! This was the one thing I wanted fixed the most. I hated using the airplane mode app. It severely affected performance.

Maybe we are all having the random reboot problem.
It makes sense if you think about it.. Mine would randomly go into reboot in sleep and the device would get stuck on the Asus loading screen. So when the device cycle through the loading screen for an entire night, you would find a dead tablet by the morning.
So far, I have encountered 2 random reboots, the only way to bring the device out of the boot screen is to hard reset it by holding down the power button.

balor you most likely got better battery due to custom rom
custom roms tweaked the battery for couple days use.. asus claimed like 9 hours on the tablet.. and like 19 with dock keyboard. custom ics roms inc
