Hello,
Picked up my phone after 2 hours of sport and noticed the battery had gone from 50% down to 10%. I actually had a missed call and the screen never went back to sleep, completely draining the battery
Does anyone else have the same issue and any idea how to fix it ?
Thanks for your help
I used to had this issue with my nexus one, it turned out it didnt go to sleep after a misscall or wake because there was a game running in the background.
Not sure if this is the same issue with you
I'm having problems with It shutting off overnight while charging. Anybody else having this problem?

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.

had this on my tab for 2 days and reflashed back to stock because battery life was awful.
I've noticed that after rooting my 10.1v, if I leave my unit unattended for long periods of time, it turns of itself completely!
It's frustrating because each time I try to turn it on after a few hours I have to wait for it to boot up which takes a few minutes.
I can confirm it's not turning off because the battery has run flat, because I have tried fully charging it, then leave it in my bag, come back later it's fully shutdown, when it comes back up the battery is still at 99%.
Anyone else experiencing this anomaly?

I had similar problem...
I just un-installed some Apps and now its ok...
I guesse some app was having problems... Honeycomb compatibility issues..

Which applications did you uninstall?
Hi all,
I have updated to new FW 8.6.5.21 yesterday. After update, I still saw that can go to deep sleep mode. But after full charge, old problem still happend, never go to deep sleep mode again.
I have no dock.
Does anyone know how to fix????
There was a post about this earlier. Here you go.
blessedswine said:
For those of you that have a transformer that wont deep sleep whether its on or off the dock, doesnt matter you can get a app for that. its called Auto Airplane Mode, and it puts your transformer in airplane mode each and every time you turn the screen off, i have noticed a huge difference in battery life after installing this app. using Cpuspy my transformer went into deep sleep for 10 mins max a night for the last week. installed Auto Airplane Mode and the transformer goes into deep sleep within a min of turning screen off now. I already had the wifi set to turn off when screen is off and everything, the only thing i did was add this app.

Airplane mode wasn't the answer before and isn't the answer now. I haven't charged my transformer since the update so don't know if it is happening to mine but if it is the same as before then it isn't radios that is causing the problem its a bug in the OS that never lets it go into deep sleep after charging. A reboot after charging usually sorted it until the next charge. That is so long as you don't have a dock because the tab thinks it is being charged when on the dock. I hope they haven't introduced this bug again because it was a real PITA when it had it before.

I also installed Auto Airplane app, but I think it is not the solutions, still no deep sleep. Because I have no dock, after charging, I reboot but still no deep sleep. Now I have to charge everyday
Mine is fine. Deep sleep verified with cpu spy.

Mine keeps disabling the setting : turn wifi off when screen turns off.
This update is ****ed up!
mine goes into deep sleep perfectly now since the update, it wouldnt before unless I used the auto airplane app. Battery life is much better now.
mine wasn't sleeping, till i did a factory reset. now its sleeping as it should.
I am having the same problem since the update. CPU Spy indicates that it is in Deep Sleep, but I am having constant battery drain in AND out of the dock. Battery says that wifi is doing the damage. I have it clicked to sleep when screen timesout. Auto Airplane Mode worked. I am not happy though. I should not have to use it.
Mine doesn't sleeping whether install Auto Airplane mode or not. I'll try to factory reset....
Happy to say mine is still OK after the update. It till goes into deep sleep as it should.

Lucky guy....
I tried fatory reset, but nothing change. Still not sleep...
How come my transformer instead of going into a completely dormant sleep mode it goes into a sleep mode where every one minute according to the clock it flashes on the screen for a few seconds just to show the time on the lock screen???

Damn, this looks like the problem I'm having: when I check what's draining the battery, the first place with 58% is Screen! I didn't see the screen flash, though.
Upd. Yes! This is exactly the issue I'm having! I checked - the screen turns on from time to time, not every minute, but still... so no deep sleep for me here

Need to check permissions on your apps as they change with updates. some apps keep the TF from sleeping others wake it up periodically to check for mail or other syncs. Need to check them all as some things you might never expect like free games keep it alive.
I'm really stuck with this problem. After full reset and only one app installed (Dual Battery Widget) Transformer spends some time in deep sleep, then suddenly wakes up. You can see it on the attached screenshot. I have no idea what happened around 3 am when the device woke up and never went to deep sleep after that.

I think mine have the same problem. Sometime it go to sleep mode, but I don't know when. Event after reboot, no application running, still not sleep....
I had this problem with mine, it turned out to be some of the apps kept waking it, and then it wouldn't go back into deep sleep. I uninstalled some of them and haven't looked back since. Specifically Facebook was a big problem, even with no syncing.

The only app installed is Dual Battery Widget (I did a factory reset). Could it be the reason?
Maybe with this you can see more.
So it happened again. Fully charge the TF for a trip. When I get to my distination (8hrs later) turn on the TF and its dead. No power and no chargers. This thing is pissing me off!
Anyone know why or how I can fix? I do have the wifi off when screen is off.
How is that possible?
Did you not shut down your TF?

It looks like you are having the reboot during deep sleep issue that started with the upgrade to ICS. The reboots can be stuck with the screen enabled and the processor actively trying to complete the boot, which drains your battery.
Short term, I would avoid leaving the TF powered up unattended for long periods.
That will prevent the total battery drain. For a longer term work around, you can try an app called Wake Lock, which you can set to prevent the TF from going into deep sleep, and eliminate the deep sleep reboots, which has helped some users, including me.
The app should be set to restart on Reboot, and select the Partial Lock, then select the Acquire Lock setting, on the red bar, which will switch to green, and indicate that it has acquired. You can also set it to show its icon in the Notification are, so that you have a visual assurance that it is working. Then just exit the app, and it will work in the background.
You can monitor that it is preventing Deep Sleep, using the CPUspy app.
I would then watch carefully to see that you aren't experiencing any more reboots during Deep Sleep.
Long term, ASUS is researching instability with ICS, and we hope to get a true fix. Until then, use of Wake Lock may help you.
Others may have other opinions and explanations, and they may be right, but this has cured my problem for the last 11days. Good luck.

No shut down. I would charge the TF to 100%. turn the screen on to see if its 100% charged and that's it. Then 8hrs or so later when I want to go use the TF, its dead. Can't even turn on.
Can this be the reboot issue or an application that is running and not letting my TF go to deep sleep? Help!

Your response makes no sense. You say TF was shut down then you say TF might not be going into deep sleep. If you power the TF down it will go off and use NO battery. you will get some battery internal discharge but TF will not come on an use battery. Try the same test shutting it off.
Ok...try again. I would charge the TF. Then check by pressing the power button. The screen goes on and shows 100%. Then press the power button to turn the screen off ( not turning it completely off).
When I want to use the TF, it won't turn on, as if its completely dead.
Suggestion?
its either a) you get a RR and get stuck in a bootloop, b) you got some app running that drains the battery, such as Winamp or c) your device is broken (not likely).
