First I would like to say I can't remember how the keys are called, all I know they are the menu and back keys, and that they should light up for a second and turn off until used again.
I'm having couple of problems with my phone being awake all times, battery drain and mostly overheating.
Some hours ago, my phone was reaching battery temperature of about 42ºC while screen off and apparently "nothing" abnormal running in background. After restarting the device, first thing coming to mind was to put it in the fridge for a couple of minutes to let it cool down.
The problem is, 2 minutes turned out to be some hours. When I removed it from the fridge, I noticed the hardware keys weren't lighting up. Restarted, still nothing. They work, but won't light.
What could it be? Maybe the low temperature did something to it? Or was it condensed water from the fridge? What can I do to make them go back fully functional again?
Issue solved, the overheating made it go back working once more.
Maybe try putting your phone in a bag of rice for 24 hrs to draw the moisture out

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.
My gf washed my phone. It had like 7% or less when it went into wash. Full cycle.
I took battery out, put in rice for like 2 days, then I put it in warm place, on dash of car in sun for 20 minutes at a time in between delivering pizzas, ect....
I throw away the battery, and I use one of my back-up HD2 batteries. I use the external charger to charge it.
I boot it up, and it works! Touch screen, buttons, internet, speaker, camera! EVERYTHING. The screen after 2 days even looks perfect. No discoloration.
One issue.....
Battery drain. It loses like 2% battery per minute, even in airplane mode and screen is off. It won't last more than 40 minutes with moderate to low usage.
I plugged it into USB via my pc when it was at 15%. An hour passes, and now it's 3%. I confirm that it is plugged in, and the "charging" animation happens.
It's not the battery, because it's brand new.
What is the issue? Is it a short? Can I fix this? The phone is 100% working condition except for the horrible battery life.
I appreciate anyone's insight into this issue....
but here is almost the exact issue posted two days ago : http://forum.xda-developers.com/showthread.php?t=1226979
you might find something there
Hmm. I never heard of that. I do know when I got mine wet it acted really odd for several days and worked itself out over time. Example: I would click open app drawer and it would call a random person or I'd click the end button and it would start the calculator.
I'm thinking there could be damage left over from minerals that may have been left over from being in the wash. Do you use alcohol to clean it up? In the thread above I gave a detailed description on how I fixed mine, worth a read I think.Have you tried to make sure you don't have any of the battery pins bent? I know they have to match up though because your able to turn it on and use it but sometimes something simple like that is really all that's wrong. I'm curious to know now myself what could cause this.

My Galaxy Note has been performing beautifully since I got it back in January. I typically get several days out of a battery charge - I'm a pretty light user. Two days ago I powered it off for a couple of hours. After turning it back on I made one short call, then nothing the rest of the day. I think it was indicating about 50% power remaining when it was powered off. That night, I was surprised to see it way down at 15%, so I charged it back up to 100%. I did note that I had left the Messaging application running, but that's all - no wifi, bluetooth or anything like that. Next day I was astounded to see that charge last only about 4 hours (according to the meter). Not only that, but the phone actually felt warm to the touch - something I've certainly never observed before. It was like it was running on amphetamines or something!
I was sufficiently alarmed by this to power it down again, remove and reinsert the battery, and power it up again. At that time it was charged up to about 75%. The weirdness continues - since then, about 10 hours ago, it has been almost locked on 75%. It may have made 1 or 2 calls in that time, but no other use at all. I do not have any of the power saving settings enabled, and I'm running Android 4.0.3.
So the question is - has anyone else seen any behaviour like this? Can it be just the battery monitoring getting out of sync? Can powering it down do that? It would not have bothered me too much if I hadn't felt the over-warm case. I find it hard to see how that could be caused by software, but it's a strange and murky world in there!
no updates installed of os.?
no new app recently installed?
Try andosensor and check battery level if its around the normal capacity when charging. Could be battery issue, could be a many things

I did update the OS, but that was a couple of months ago, long before this happened. I observed immediately after that update the battery usage seemed to get worse, but after a couple of discharge/recharge cycles, it got its act back together and has been fine since. That's why I was wondering about monitoring software getting out of whack this time - but couldn't see how software could make the case warm!
No new apps for at least a couple of weeks. I'll certainly have a look at Androsensor, thanks for the reply.
Your phone isn't going into deep sleep. Use an app called CPU spy to check this.
Mine usually recovers back into deep sleep after I reboot my phone.

Check for partial wakelocks. Otherwise, if you're complaining about battery percentage dropping when you reboot, that's because the battery monitor believes that the battery is not as charged as it really is due to high CPU load dropping the voltage.
Sighhhhhhh ...... the case:
- Playing Haning with Friends (Zynga) with phone plugged into charger
- Fell asleep, left game on screen
- woke up next morning, phone was hot enough to burn
- turned off, removed battery etc, allowed phone to cool.
- turned back on, so far (it's been about 4 hours since I woke up) phone randomly goes off
- doesn't seem to be linked to any particular activity or time frame - within 5 - 15mins it goes off, sometimes on a call it goes off
Is it a lost cause? :crying: Or something that I can do to fix it? Or something that will correct itself with time? Change the battery perhaps (though all the battery monitors say battery is fine hrmph!)
Opinions will be really appreciated.
Cheers,
Mex.

I'd try to change battery. You should find cheap ones online easily.
What about taking pictures with flash? My phone dies from time to time because of its (supposed) dead battery when taking pictures or when ringing.
Surprisingly enough, there are A LOT of battery threads in these days.. it's obviously a conspiracy
Maybe ur battery is completely dead?
Battery juice might have all burnt out.
My laptop dies 5 minutes after I unplug the charger.

Does the phone turns itself off even when pluged in?
If yes, then maybe its a hardware problem
If not, its definetely a battery's problem. In this case, try running complete discharging and charging cyrcles (2%->100%) and leave it pluged in for 8-12 hours, even if it says fully charged.
Any signs of swelling on the battery?
And when your phone goes off randomly.. What is its temperature like? I mean does it get hot and then turn off?
Thanx for all the feedback.
I discovered a couple of hours later that it is indeed the battery.
Doesn't go off when plugged in.
Battery monitors say the battery is fine but it can hop, step skip from 30% to 9% in a short whatsapp chat.
No bulging or heating, just goes off
On the up side I guess its a blessing that its not a hardware issue.
New battery it is then... What are the chances of successfully suing Zynga for the replacement lol, the game should come with a warning!!!
Tnx.

here is the situation, while i left my tablet in my backpack on the way to work, i noticed my backpack becoming very warm.
to my surprise, it was my n10 and upon inspecting, the device has already died 0% battery and cannot turn back on unless i plug in the charger. Mind that i did not do anything prior and it was left untouched since last night with the battery at approx 80%. And battery drain happened while it was in my backpack as the device was unusually hot when i took it out.
Now the weird thing too is that while it's charging, it completely froze to a black screen at least 3 times, everytime needing me to hold the power button for few seconds to reboot the device back.
it's the first time this happens on my n10 and it wasnt a result of a new rom or app i've installed as i haven't touched my current configuration for months.
anyone experienced this and know what might be the cause? battery dying/faulty perhaps?
