Random Shutdown

When my phone is sitting idle (screen off) it will randomly decide to power itself off. Has anyone else noticed this? Any ideas on what could be causing it?

you mean randomly power itself ON, right?
if that is the case, it's normal, it just mean it woke up to connect to the internet, to get updates of news, emails, or whatever it was scheduled to pick up

nope. i mean it randomly turns itself off. this topic is being discussed over on the att captivate galaxy forum section.

interesting, so it's going from stanby mode, to complete OFF... nope never seen that happen to my i9000 model

yep totally powered off... completely sucks... looks like there are a bunch of ppl that have this issue with the captivate on att. $10 says its some lame piece of software that att puts on your phone that's causing the problem.

it's possible, i've read here a few users having crazy power issues (battery draining very fast) with their SGS i9000, but after wiping it out clean, to start anew, then the power problem is gone away.
so yes, a software could cause something weird like that.

Factory reset and so far so good
Hey guys,
I use a Galaxy S here in Hong Kong and I had the same random shut down issue constantly happen when my screen went off...
I tried everything, check temperature of cpu, etc. etc. and nothing worked, it just got worse and worse.
I even changed the battery to use the spare one that came with this. Still problematic.
Used SET CPU to limit the cpu to 400mhz, still problems.
Finally I did a factory reset and so far so good.
I only have the original system installed with the Remember the Milk app installed.
24 hours, no problems.
Installed AppBrain app.
Then I installed 3G WatchDog
12 hours, no problem.
Then I installed Paperdroid
12 hours, so far no problems at all.
If I run into an issue I'll post it here. But I think it definitely was a software issue.

Update - it randomly shut down on me
Alright guys, it shut down on my randomly today in the afternoon......
I dont know if it's the re-charging that screwed it up?
Because after my factory reset, last night was the first time i charged it....
Hmmm

This happened to me too - two days in a row until noon it would shut down two or three times - i uninstalled SetCpu and for now (24 hours) it hasn't happened again. I am not sure if it was the one responsible but it started happening after i installed two programs and i uninstalled them after it started happening. I uninstalled Visual Task Switcher first but on the next day it turned off again, then i unsinstalled SetCpu and it hasn't happened again - maybe some wrong profile settings but i didn't feel like experimenting

I had this issue once too in about 40 days.
I was reading an sms and then i turned into standby and put it in my pocket. Later, maybe 40 minutes i came home and my phone was completely off. I do not remember if i had to take out the battery before to get it on again.
I was wondering why it happened. Maybe it was caused by an app i had opened. Battery still was at 40%.
But since it only occured once in 40 days i doesn´t bother me.

Interesting you mention this as it just happened to me today for the first time. I took it out of my pocket and wtf? The phone was off. Very strange... Using the i9000 on the stock Eclair rom.

Should send back for warranty

software clash?
Well the phone suddenly switched off for me, but this time I turned off APPBRAIN and so far so good.
In fact, I came across an app called NoLED and since it kind of keeps ht phone on, while I have it on my desk, I'm able to be notified of stuff and so far with that, the phone hasnt' shut off.
I'm still experimenting with what works, but try turning off AppBrain and see if you still have the random shut off issue....

i use app brain all the time to keep my apps in sync
not the cause of the problem, that's for sure
my phone can last a whole day even with app brain running

OP, do you have MSN Talk installed on your phone? I have this same problem, seems to happen more when I am running MSN talk in a low signal area.

«try a new sim card. «Could be faulty. «i am on my 3rd phone and all of them had this same problem. «i bought a new sim card 4 days ago, and hasnt happened since. «but then again, this problem usually happens to me once every 3rd-5th day anyways, so i dont know if i am in the clear yet.

Me too, shutdown everyday
Hi guys
After upgrade OS to I9000ZSJG4, Phone random shutdown everyday.

Yep still shuts down
Tried keeping AppBrain off, still shuts down.
Used NoLED so the screen kind of stays on, still shuts off..
So far shut off on me after 40 hrs... this is really stupid.
I am this close to taking it back, but I genuinely think it's a software issue than a hardware issue...sigh
Anyone have any luck figuring this out?

Same problem no solution yet
Hi
I too have the same problem, haven't found any solution yet.
The temperature etc is all good, there is no pattern in shutdown issues.
I have tried factory reset and no new application, it still shut down while using in built browser.

I had the same thing happen to me while skiing in Whistler last weekend. It died twice. I attributed it to the cold. I normally use a 3000mah battery up there, but left it back the house that day. Afterwards while charging in the car and even charging it at home it died prematurely again. It was the eBay aftermarket variety 1500mah knock off. I have since changed back to the Samsung OEM battery. I haven't had an issue with it since. My assumption is that the knock offs in my case cannot handle the heat cycles of charging and then the cold as well as the original. Or they have a limited lifespan, well below OEM specs. I am now only using the 3000mah battery on the weekends to hedge my bet on the quality of manufacture, as it seems to be from the same factory as the 1500.

Gets hot and uses battery while idle

Recently I have noticed on several occasions that my phone have gotten hot and started eating away the battery. One time I had around 30% battery and the phone was laying in my pocket. I felt the heat through the pockets and took it up to see what's up. It then had 0% battery and turned itself off.
When looking at battery use in settings, it's hard to pick out one specific application that might do this. If anything it would have to be "Android system", right now it's tied with the screen on 40%, but I charged the phone an hour ago and I haven't used the screen much.
Edit: I should add that the same thing just happened, from 99% to 89% then it stopped. That's why the information above about battery usage is relevant.
Do you think it might be hardware-related, like a partial short circuit or something, or is it most likely a software thing?

Bump. 10 signs.

Had mine for a few days, have not experienced anything like what you describe
I have though felt the screen get hot when turned on full brightness and reading a e-book on it (white - black text)

Well this is while it's laying in my pocket, with the screen off, so it's not the screen. (it's the battery that gets hot)

Take it back.
[Funny story that probably isn't relevant. I had a dodgy micro sd card that made my phone drain battery super fast and as a result my phone got incredibly hot. Took it out and it's back to normal.]

Sounds software related to me, your android system should definitely not be 40% of your battery. It sounds like some rogue app/process is utilizing your cpu and thus your battery very heavily. If you select the "Android system" in the battery usage list, does it not give you a further breakdown of what is included in that that is using your battery? Also, what does it say for the cpu time for the android system?

May be firmware bug
I've had this happen to me a few times when I was running the original firmware. In some early firmware there was a bug related to switching between wifi and 3G, which would get it stuck so that you couldn't toggle wifi on or off. The times this happened to me, it was also stuck in the wifi bug (although I had the wifi bug and it didn't drain the battery).
I now run the newer firmware (JG4) and both problems have stopped.

I've had this problem with my asian i9000 since the beginning. The app called Top showed me that it is ksoftirq/d that is running and System Panel showed me that the cpu was running at 100% at 1ghz.
At first the only solution seemed to be restarting the phone. However some information shared on this forum led me to try restarting wifi which also works. For that thread search for "ksoftirq/d."

I have had the "stuck wifi" bug, but I'm not sure if it was happening the last time this happened. I'll check it out the next time.
There's no official firmware update on Kies for Norway yet, so I think I'll wait for one.

Had exactly the same problem and tracked the culprit - it was Fancy widget in my case. Removed it, installed Beautiful widget and all is well since
Sent from my GT-I9000 using XDA App

That might actually be it. If I'm not mistaken Fancy Widget had 30% battery consumption when I checked. I deleted it just to see if it would make a difference. So far so good.

Some details:
Fancy Widget will hit the 100% cpu on auto-refresh if there's no data connection available (either wifi or cellular). It seems there are 2 bugs with Fancy Widget; it ignores "auto-refresh off" option and it tries to connect to server even when offline.
A dirty work around would be to set refresh time to let's say 12 hours and make sure to manually refresh at least once every

That makes me even more convinced that Fancy Widget is the culprit. I usually have cellular network disabled (APNDroid On/Off Widget) to save battery and my wifi connection keeps loosing connection, probably due to some software bug in XXJF3 stock firmware.

Overheating and battery life.

I don't know what all your experiences are, but I noticed the past few days that my epic is getting hot on the back.
I also noticed that my battery is draining more so than usual. When I got the update last week my battery life sucked, but now since this overheat thing it's gotten worse. It drops a lot even when in standby.
I do not have gps, wifi, anything else on. I am not rooted. Didn't do any battery tweaks. This is completely stock di18.
This is normal use with 3g. It's getting annoying and I'm hoping someone has an answer. Thanks!

Do you have any email accounts configured in the mail application?

This happened once or twice - I rebooted the phone and all was peachy.

Sounds like you have a rogue process wearin it out.

Yeah my phone overheated yesterday while charging....this phone has a few more steps to go before it really beats my hero...
Sent from my SPH-D700 using XDA App

I partly found out what the problem was, but it seems you guys are ahead of me. I had some process keeping my CPU running at 95-100% nonstop. I still haven't figured out what the process was, as now it is back to the normal 5-15%, but I'll have to keep an eye on it now.

the task manager widget turns red and it shows you what process was causing it...for me it was the xda app...a few times.

I think my problem was not backing out of WordFeud. I didn't notice anything on the task manager though. Hasn't happened since that one time.

this happens to me when i'm plugged in and using gmail. screen flickers and then shuts off. the screen-off battery indicator shows the batt. gauge and a little thermometer sign next to it indicating it's too hot.
wtf?!?! this has to be a defect. anyway, is there any official word on this? any pr from sammy/sprint?

i have read elsewhere about some epics resetting themselves a few times a day which could indicate an issue with heating (at least on a pc). so if you think it might be hardware its possible. otherwise keep doing what your doing, monitor your processes for anything thats eating it up, go to about phone > battery use > cell standby to see your time without signal. the higher this is the more battery use. also, might want to consider a startup manager to prevent the 2 DRM files (search forums) from running as this can affect batt life too
you can also use setcpu even (free on here, search it) to throttle your cpu down when it hits a certain temp.

This is very interesting... My wife and I both have this phone, she has had this happen several times after the last update (I though she was just crazy). Me on the other hand... No problem!
I need to look into this a little deeper.

The only time my epic's battery gets hot is during heavy use or gps. Gps/Nav makes it heat up like a mofo. But other than that... *knocks on wood* Its all good, no problems. As far at battery life, I am rooted and using SetCPU to turn down the processor while the screen is off, helps a ton. Not using anything other than that... was using juicedefender but then I started not getting calls or text...

One thing, I learned, that didn't help my battery was putting my phone in the locker at work. That thing must have killed my TWS and ate my battery alive.

i feel like this thread will start to die but i had a weird somewhat related issue last night. i too have had maybe 3-4 times where i woke up to my charging phone with the red LED and a screen that would not turn on, battery pull, worked fine.
however, THIS morning my phone would freeze like 30 seconds after boot EVERY time. tried a few things to no avail until I wiped, reinstalled my ROM (aosp 0.4.1) and the data from a previous backup (which was the way i got that ROM to first boot successfully according to tips in that thread).
so this worked, but i couldnt figure out why my other steps wouldnt. had to be something in the data partition of my system at the time, since changing that worked. the only thing i could think of is that app watchdog which someone mentioned to track processor usage by apps. anyone else ever experience this?

I have experienced this once when I was playing Robodefense while the phone was charging. My phone tends to get a little warm when it charges, and hot if I run something intensive while its charging. Wondering if this will be an issue when I use this phone for GPS nav while plugged into my car.

"I'm having this problem too...I didn't get any warranty for this either. Any reasons onto why this is happening...I woke up this morning and picked up my burning phone lol the temp was at 50C so I took out the battery and let it sit for 15 mins...it went down to 30C, then after not touching it for another 15..it was at 17C...very odd...what should I do, this crap is going to die within the next hour I'm worried it will fry the hard drive or something. Need help! " - I wrote this on a diff. forum a couple days ago
I dont have anything on, no wifi, gps, or any 4g (lol only if I could find it)...I even got rid of my facebook/twitter/weather updater widgets. The only thing that updates is email, and that's only if I click on it. The battery has been dying a lot faster and I charge my phone next to the window now because its like 20 degrees outside here in Chicago, so that brings down my phones temp lol....and today, my phone's battery life went from 100 to 5 percent in about three hours of barely using it...wtf?!
Also, another problem...sometimes when I lock my phone and unlock it after taking it out my pocket or something, the screen doesn't seem to respond...I keep swiping my finger over it to put in my password and it wont do anything and it only works when I slide up my phone for the horizontal view. This happens like 4 out of every 10 times I open phone.
Very embarrassing especially if your trying to get someones number down, I stopped showing off the phone now ...lol

[Q] A500 shutting off overnight while charging!!

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.

Bizarre battery usage behaviour

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.
