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.

HOT charging temperature

I am charging it using the provided USB cable and adapter, but the phone is almost too hot to touch when I wake up some mornings. It quits charging because of it, but it still remains very hot. It happens irregularly and I cannot pinpoint the problem.
I am running completely stock AT&T.
Can someone help me figure this out?
Edit: some more info: The cell radio has turned off with this issue at least twice. It turned back on after a restart. Airplane mode was not enabled, so I am not sure why this would happen. When charging at night, I run the Sleep As Android sleep tracker, and it's on my bed, but I run it every night and I am not sure why it would only give me problems occasionally (every ~10 days or so). It's possible I bump it in my sleep, but would that cause this issue? When I wake up it is fully plugged in and too hot to continue charging.

Is there any wakelocks keeping your device running? Look into it. Something could be keeping your device running in the background. Or perhaps something is turning on your device.
Worst case scenario is that you have a defective device in which I suggest you go see an att repair center or call att so they can exchange it due to defective issues. The replacement will be free.

Well put, reminds me of a scenario I had on my SG3. When I had first gotten my SG3 awhile back it would give me temperature warnings every so often (2-3) days. I found the problem to be that a couple of my applications were running background processes that were very cpu extensive and keeping my device awake. This caused the CPU to ran at nearly max frequency throughout the entire night, thus over heating my phone. I wiped every application I had and reinstalled and set background permissions to not allowed for a majority of them; this resolved the problem.
I haven't experienced this at all on my SG4, but I still disallow a lot of my apps to use background processes unless necessary. I did read online that some of the SG4 devices did have a defective heat sync though, however I'd try removing all your applications until you're down to bare minimal stock and reinstalling and keeping an eye on what could possibly be running your CPU up when your phones locked.

I'm guessing that it has a spike in temperature, it turns off the charging, but it still is plugged in so the temperature keeps going up. Hottest I saw on it was around 65 deg. Celsius.
I attached a few graphs of this happening on different occasions (one portrait is the same day as the landscape). The fast drop-off is where I unplug it and let it cool and reinsert the charging cable, and it surprisingly does not get hot again. No restart is necessary, so I doubt there is much to do with the phone's CPU but I could be wrong.

[Q] S5 Dead Overnight

I have the SM-G901F version, 805 processor.
I finished charging my device last night at 100% and took it off before sleep, all was well. I woke up this morning, and it was dead at 0%.
Something similar has happened twice in the past and that is the screen refusing to turn on, and when it does it jitters a lot and says a certain app has crashed. The first time THIS happened, it said nova launcher crashed. The second time, same day, I locked the device while still in whatsapp and the same thing above happened but this time it said WhatsApp crashed, this leads me to believe it's not Nova launcher causing it but you never know. During the time of these crashes when the screen was off, I had rapid battery drain.
This is why I think overnight something like this happened, and since I didn't try and wake it up like the other two times the battery continued to drain. However, I have attached an image of the battery info suggesting that the phone app caused this.
*I close all apps before sleeping, all the time.
*Data off, blocking mode on.
*Never leave it on charge over night
*UK device, only had it for about 1 month.

...

android doesn't need apps to be closed manually.
sometimes its better to backup all your data and start fresh mate. that's will isolate the problem a bit more.

Wake time?

Hi, new owner of DT2 after returning my galaxy7 edge. I'm having an issue with wake lock. When I don't use the phone for an hour or so, and haven't touched it, my battery barely loses anything and the wake time under the battery setting reflects that. But when I'm casually using it - sometimes using it for two or three mins, then not for 29-30, my phone seems to stay awake a lot when the screen isn't on. I thought this could be a rogue app, so I'm running it in Safe Mode, but I still see the same trend. Does Moto active display cause the phone to wake every time it reads motion?
Attaching screenshots. The battery charts are when I had it in Safe Mode. The gsam readout was in regular mode. Based on how active the phone was, I would've barely gotten 2 hrs of SOT

Hi. Generally, Doze, the feature that allows your phone to barely sip power when your phone is not in use, will not kick in until around an hour. Yes, Moto display will wake the display every time it thinks you are trying to use the phone but it should still use only a tiny amount of power. Also, don't put too much stock into the projected battery chart. Sometimes, it is very conservative and other times, it is wildly exaggerating. Hope this helps.

I did a factory reset on my phone and left the phone sitting for about an hour. The awake time was still represented about 30-40% of time on. My phone has been getting about 2-3 hours of SOT over the course of a 12 hour day. Seems like the awake time is really eating the battery. I wonder if others are having this issue. I didn't have the phone before the Marshmallow update, so don't know if that's the culprit.

I have noticed then when I keep the phone aside overnight.. idle condition (wifi off, location off, data off) and go to sleep.. I wake up with a drop of 8-7% drop in battery, is it normal? Because none of my previous phones showed such a drop in battery. Anyone else facing the same issue?

Deep Sleep issues?

My phone has not been able to get into deep sleep. For the last few days that I've checked GSam, it's always been at 0s of deep sleep. Just checked right now and after 21 hours, my phone has gotten 10s of deep sleep. I've done a search and looked through many pages of posts on some of the various battery discussion threads but I haven't been able to find anything. Does anyone have a possible remedy for this or explanation of why it's happening? Is anyone else having trouble going into deep sleep?

Mines is the same, I assume it's because I charge my phone every night, which is really the only time my phone would sit still inactive long enough to actually enter doze.

I might of fixed my draining battery issue so maybe you guys can try it out too. My issue was my phone would not go to deep sleep and would stay awake even when the phones display was off so something was keeping it up. I tried all the different methods out there including the package disabler and doing the hard reset with the cache reset. I was browsing the developer options in the settings screen and looked at my running services. I noticed that my contacts and a. Program called com.qualcomm.location had a message next to them saying restarting while all the other programs just had a countdown of how long they were running. So I clicked on each and pressed stop and I also re-downloaded the package disabler and disabled the com.qualcomm.location. after all that I synced my contacts again and just did a simple reboot and after that my phone was able to deep sleep. Now my battery is not draining like it did. So in my case those 2 apps had an issue and kept trying to reset itself so the phone was never able to sleep. I would recommend looking at your running services in the developer options. go into the running services and see if anything is trying to restart itself over and over again

So I did finally achieve deep sleep. I tried a few things from the temporary battery fix thread and I wasn't able to pin point one thing which worked, THEN, I restarted my phone and it wouldn't go into deep sleep again. I tried wiping the cache and restarted and suddenly it's going into deep sleep again....
I'll keep an eye on it and will update if anything interesting happens.

I finally charged my phone prior to going to sleep and it finally did dose last night, the phone has to be stationary to enter deep sleep

Doze and deep sleep seem to be too different things. My phone will sometimes doze without going into deep sleep. What's really weird is that sometimes my phone will randomly stop going into deep sleep and a clearing of the system cache immediately fixes this. There have been at least two times I can confirm I *only* did a cache wipe and the issue was remedied.
Does anyone have any idea why this is happening and why clearing the cache helps?

Anyone figure this out? Also is everyone on stock? Im rooted and on superman rom, this is happening to me every day now after i charge it over night. I have to restart my phone to fix.

same for me on Galaxy s7 flat exynos sm-930f, no root, stock rom
very annoying
if you find a solution suitable for me (without root) please let me know

same here to me stock exynos s7 when plug off the charger in the morning have to restart the phone otherwise battery dies half day

I figured out that for my phone it defenitly is somehow connected to the fast-charging function.
When using the fast-charger the phone doesn't go into deepsleep anymore.
It happens as soon as the phone touches the fast-charger, it doesn't even need to fully charge for this to occur.
When charging with everything else, incl. Qi nothing happens, but as I said, after the fast-charger was connected - no deepsleep.
At least that's what I observed, no guarantee that this affects everybody.

It is the same issue that has been discussed for a while in "high android system battery drain" thread. Read up last few pages.
