Phone randomly stops sleeping

My phone will randomly stop sleeping, this has happened pretty much since i've gotten it.
I will launch spare parts, running near 100%. Check partial wake lock, nope nothing. And nothing under any of the other menus in spare parts that would indicate it not sleeping. This will occur after a couple of days even after installing no apps, restarting does not fix, neither does pulling battery. It will just start happening and only way to fix is data reset / factory wipe until it happens again, but when it does start happening I might've not even be using it at the time.

Okay, i did actually finally fix it after months without factory reset, it appeared to be when 3g and Data-always enabled was ticked.

If this fixes my no sleep problem, I will name my first child after you.
I've been detailing the steps I've taken to resolve my no sleep issue on another forum, with the last action I took being a flash to factory ROM from huaweidevice.com, changing absolutely nothing on the phone for 24 hours, rebooting, and waiting another 24 hours. Without a reboot between charge/taking off charge, it would be 100% running. If I took it off charge and immediately rebooted, running would be more like 30% (ie: 'normal').
I'll give 'data-always' a go

Wooh, nah for example my running time is 8.7% and screen on is 6.1% so that is pretty good, thats over the course of about an hour

Okay im unsure now, was all fine yesterday, woke up at 7 to alarm, lost 2% overnight. then just put it under my bed but now that i've woken up i've lost 18% because it just stopped sleeping again. I didn't do anything except turn it on check battery, and turn it off. So back to being confused again

Still having this problem, for example. It was sleeping fine when I went to bed then at some point during the night just stopped.
Running 64.6% 10h
Screen on 10ish% 45 minutes
Highest item with partial wake lock in spare parts is like 5 minutes, no other indicators.
This is happening no matter which ROM i try.

Considering a stock ROM with exactly 0 changes still has sleep issues, its clearly a firmware "thing".
For me, it happens after being taken off charge.
For e.g. Last thing before bed I check my running time, and its somewhere around 35-40%. Plug into charger. Take off in the morning, goto work etc, check my run time and its 100% even without the phone being touched.
For the moment I just downloaded one of the "root only" reboot widgets from the Market. Its just part of my morning "get ready for work" routine to hit the reboot widget and reboot my phone.
Its a bit of a PITA but until new firmware is released I cant see a way around it.

Hey don't know if you've tested it further than that. But its much appreciated, that rebooting after charging does seem to work . But just wondering, if you know... does it only do it when charging via usb (computer) or AC or does it not matter?

I have exactly the same problem.

I also noticed that reboot helps, but only for a while. If i want my phone to go to sleep mode when the screen is off, i would have to reboot it few times a day... Turning WiFi/GPS/Auto-sync on/off does not have any affect on this.

As per your suggestion via email, I tried the Malaysian firmware.... It seemed that 'running' time was down alot, but battery life was still pretty average. That was doing nothing more than installing the Malaysian firmware and entering my Google account - no root, no launcher changes, etc.
The lack of Swype was a bit of a downer too
I gave it a whirl from 6:30am to around 5:00pm and 'running' was right down in the 10% range, but battery was still down to ~45% over that time in 'pure' stock form. DAMMIT!
Ah well. It was a good thought and hopefully it worked for you I'm back on roadhound + the OTA update as of about two hours ago.
I'm going to scour the SGS forums and see if anything there can be applied to the U8800 RE: battery life improvements.

Oh yeah sorry, try using something like juice defender to disable 3g when screen is off or something. 3g radio keeps it running, but it doesn't appear to be, this will stop the battery drains.
EDIT: That does work but its not ideal, turns out the u8800 and the u8800h use the exact same radio so im not sure now, don't know if there is any possible way to figure it out.

Sometimes i have 3g data connection running, but phone goes into the sleep mode when screen if turned off. So this is not the cause.

Oh no, this is just the case for the U8800H malaysian firmware seems normal for all U8800 firmware.

I'm not using u8800H firmware and i have this bug.

Hey guys.
This may not really be the thing you need but I was having similar problems and running 100% on without sleeping etc and came accross another forum where this was an issue (cant remember where)and as trivial as it sounds the solution for me was to go into settings/ applications/ manage applications and running applications and go down to media storage and clear the data. I do this now and then when I have this problem and it seems to help.... Maybe worth a try? It seems to be an issue with a particular media file. I also try to reboot my phone after every charge. Note that my phone is totally stock

Thanks for advice, but unfortunately this didn't help either. For some unknown reason, my running time is again 100% although the screen is off most of the time. In Partial wake usage, Android System is in the top of the list.

Oh, Android System partial wake lock seems to be a different issue, but maybe someone can help you out. Whats happening here is running = 100% yet there is no partial wake lock held. Quite unusual

Yes, it is confusing also because i have tried different ROM's with same result. I would have thought that all u8800 owners have the same problem.

same problem here...

[Q] Phone turning off by itself and renders itself off ever since

Hi all,
My first post here and I'm posting it at a pretty depressing mood.
I've just bought my phone from the states and brought it back to Hong Kong for my own use. Last night, I've been toying it for a couple hours with everything going perfectly fine, but suddenly the phone turned itself off. Everytime I try to turn it on the phone just turns itself back off again. I couldn't do anything.
Has anyone come across the same problem? I've done a hard reset but to no avail, the phone still shuts down right after turning on, it's pretty frustrating to turn on your phone just to see it telling you it's turning off, really frustrating tbh.
I've called google and requested for a replacement so problem's kinda solved for the moment. I just want to know if I'm alone here because I've pressed the operator a couple times and she refused to tell me if mine was an isolated incident or not, for obvious reasons.
I haven't done anything to the phone except installing a couple apps like Aldiko, whatsapp, facebook and a Chinese keyboard (since I'm Asian apparently). I've installed all of them in my old phone and none of them caused any problems so I just want to know if I'm alone and what do you guys think the root of the problem is, or solutions to it if there are any.
Thanks a lot!

Mine is happening the samething, glad Im not alone. My was running fine on rooted Modaco custom rom for a few weeks then all of sudden the phone auto shut down like it has its mind. I installed Cantonese keyboard and camera mod too and some other apps. Currently Im tracking down the source. Now I have franco kernel and madaco rom on clean install running with no other app install to see if it will shut down or not. If it does Im going back to stock to see if samething happen.
I have to boot it couple times until it doesnt shut down itself anymore. Sometimes it be stable for couple hours or couple minutes or instantly.

I have the same problem, Just got my phone from google everything is stock nothing has been changed and the phone just turns it self off and then i cant turn it back on for sometime.
Does anyone know what causing this problem?

Mine also turns off multiple times a day, sometimes by itself, sometimes during a call, often when taking a picture.
Today every single time I took a picture it would shut down.
I'm f*cking pissed at waiting 5 weeks to get a useless phone... and god know how long it will take to get a replacement if I ca get one.

Hi guys, I have the same problem too
I've used my Nexus 4 for 2 weeks without any kind of problem when suddenly it turned itself off. If I try to turn it on, the phone just turns itself back off again and I haven't solved the problem even with a reset.
But I've noticed that the battery doesn't charging even with the charging cable. I think the phone detects that hasn't enough battey level and for that reason turns itself back off.
Do you think it can be an harware or software problem?

Damn - i have recently been having the same problem! It only happens (so far) when i'm charging the phone overnight. I wake up and it's off and takes a few tries to get it running again. I'm rooted with stock. Does this mean we all need replacements? Ugh!

The exact same thing happened to me as well. I charged it overnight, unplugged it and it was off. I couldn't even turn it on again - I had to keep holding the power button for ~15 seconds plus try plugging/unplugging the phone to the charger etc. and it finally powered on. I orginally thought it may have been a kernel issue since I had just flashed Franco r29. However, looking at his thread, nobody had that issue.
I'm glad I'm not alone but this issue really worries me, especially if it is a hardware fault. Google will replace it but I don't feel like going through the fuss since God knows when the replacement will arrive. I hope this get's 'magically' fixed as it has only happened to me once so far.

You know, I'm looking at my battery history (using battery monitor) and i see the period that the phone was shut down and then when i powered it back up this morning and i notice the battery temp is extremely high so it probably has to do with the phone shutting down due to overheating, which obviously shouldn't happen. I wasn't using the oem charger, so I'll switch to that for the time being and keep an eye on temp. Hopefully it's a software bug and not a faulty battery because it should definitely be cutting off charging when it reaches 100%.

[Q] Charging Problems

I have noticed 2 problems that only seem to have occurred after upgrading my Nexus 4 to Android 4.4.
Sometimes, for no apparent reason, the phone will simply refuse to charge. At first I thought it might be the micro USB port going dodgy but I've ruled out a hardware issue since simply rebooting the phone fixes the issue every time. I've also tried different chargers to see if that made any difference.
The second issue is that when the phone has finished charging the phone screen turns on (as it has always done), the problem is that every 2 or 3 minutes it flashes on again, and again, and again. So at night my phone screen is constantly turning itself on and off. I always thought it was stupid that the screen turns on when it has charged or removed from the charger and wish I could turn that off anyway.

Stock ROM, unlocked but not rooted. I haven't tried resetting due to the hassle of having to reinstall all my apps and setting everything up again.

Hmmm.. Is there any way the apps and it's settings be backed up EXACTLY like how they are and then restore after factory resetting the device?
Not to mention, all this WITHOUT root and being COMPLETELY stock?

Random shut down

Today I picked up my phone up to send a text and it was no longer powered up. It had randomly shut down.
When I switched it on again I noticed it has lost its battery stats so looks like they were reset or lost. There were no user apps installed on the phone either.
Have you had a similar experience?

You could try to reset it or take it back. Could be defective!!!

Was it somewhere it was hot? Maybe the phone got too warm and hit the shutdown temp?
Honestly hard (read impossible) to tell you what happened. Have any more info / logs?
I haven't had any issues with heat or shutdowns at all. I get 6+ hours SoT every single day at 75% brightness. 100% stock and unrooted. I use my N5 for all the modding aspects like V4A, Xposed, etc. I want this one for Android pay.
Anyways my uptime has been running since I unboxed it on 11/9/15. No issues.

I actually had it reboot in my pocket yesterday on the first day i had it but I already installed a custom ROM so no testing it out now.

It was only room temperature. Here in England at 18cc so not too hot, but good point.
I read about the same thing happening with a N5 and it turned out to be a defective mother board.
Guess I should return today then... Bummer

If you just got it, might want to see if it happens again. I had one random reboot the first day and its been fine since.

My phone has started doing the same thing. Twice in 3 hours.

Same here...... 3 times reboot..... And now 2 times shutdowns.

I started having random reboots after I installed greenify. I tried several settings but had the same problem. It rebooted 5 or 6 times a day. I uninstalled it and haven't had any more problems.

I had my phone shut off yesterday and wouldn't boot until I plugged it in (it was at 80% battery). I then noticed that once it booted, it had deleted all of my paired Bluetooth devices.

Was just having the same problem but it was happening every 30 seconds to a few minutes. Deactivated greenify's device admin ability and now it's gone. Hopefully it stays that way, though if it comes to uninstalling it, that's fine since there don't seem to be as many background apps running on the 6P compared to my verizon LG G4.
Nevermind had to uninstall it.

Shut down, and a little warm
My nexus 6p shut down nearly every day, I just picked it up and it was shut down, I looked under battery and I could see it has been shut down for hours.. hope somebody knows anything about this problem.. I don't think a hard reset will help, because when I got the phone I installed all the update to Android 6.01 (MMB29M) and then I did a hard reset to make sure the phone was as good as it could be..
But maybe I'll try one more hard reset, just to be 110% sure

I'm having this problem too. It happens a couple times a day, and I think it always happens right after I pull it out of my pocket and try to unlock it. I'll feel the vibration from the Nexus Imprint fingerprint sensor, but then the screen doesn't turn on. So I try the power button, and nothing happens because the device is suddenly off. So then I hold down the power button to turn it on, and it boots normally.
Someone mentioned this happening with stock software, which makes me think it's a hardware problem, so we'll need replacement devices. However, I do have Xposed and GravityBox installed, so I need to rule those out first by removing them for a while.

I've had the phone for two weeks now and so far this happened twice.
The only two things that come to mind:
- enabling SRGB in the dev settings
- using a bluetooth headset
Has anybody pinpointed whether this is a HW or SW issue!?
How common is this ... I've seen ppl complaining in this thread and in Reddit also on random reboots as well
Thx

Still happening...
I am having the same issue. Did the reset to factory with no help. Phone was not hot, was sitting on my desk with 81% charged battery. This is the 3rd or 4th time in a week it just shuts itself off for no reason. Has anyone found anything??

I'm having this problem too, now on DVP 3 it's even worse. But I notice today that alarm clock works, but the screen won't. So I think is a SW related, the screen won't wake up, and after a while if you press the buttons the phone reboots. Anyone have e ideas how to fix this?
Enviado de meu Nexus 6P usando Tapatalk

facing this problem since may security update, on purenexus , dirty unicorn and rr rom. dont know if it hw or sw or simply power button getting pressed accidently.

I think I need to reopen this post, coz' I've been facing thif problems for so many times this week so I google around and come to this post.
Has anyone come to a workaround or point out if it is software or hardware related yet...? If it's hardware then I think I'm gonna go for a replacement then!!!

Note 4 Randomly Turned Off Won't Turn On Anymore

Hi everyone, after trying everything I could to fix this phone I don't know what to do anymore so I'm here asking for other options.
So the story is, I was just using my phone as I usually would that day and it just randomly turned off and won't turn back on anymore.
(it randomly turned off before a couple of times but it would always turn back on)
- It won't go into recovery mode or any other of the 'modes' (I tried all the different combinations of pressing the keys).
- It's not a battery issue as I've tried my battery on my brother's phone (he has a Note 4 too) and it worked fine and I tried his battery on mine and it wouldn't work.
- I tried the 'drain' method (removing the battery and holding the power button for a minute or more).
- I tried using multiple cables to charge my phone nothing worked.
I didn't drop my phone, wet it, root it or anything and it was working fine the day it happened until it just powered off by itself. When I plug it in my laptop it would make
a sound indicating I've plugged something in but nothing happens. It was version 5.1.1 model SM-N910F.
TLDR; Is there a way to somehow recover the files in the internal phone memory?

This is happening to me as well, also started in February. I'm suspecting a hardware issue. Tried it ALL but rooting. In the past 30 minutes my phone has booted and rebooted itself till it died. If someone can confirm it is a hardware issue. Maybe it's time to unite and get it fixed for free. ~Tamarnouche

Recovering data from a brain dead phone may not be possible, as it probably need some internal component replacement which may erase the data(Mostly). Have u tried connecting it to pc? Better give it to service immediately. Good Luck.

My phone has done exactly the same thing, happened in February too, initially it did the random freeze then started to reboot itself, went back to stock software and full wipe but no improvement; now it will only boot if I leave the battery out for a prolonged period, otherwise it doesn't respond to the power button at all.
I occasionally see MMC Read Fail on boot but not all the time so presumably the internal memory has a bad contact or is failing.
Can it be replaced?

I have the same problem with my Note 3. Only if I keep the battery out for a long (over 24 hours) time I can see the boot logo. So if you find a solution to this kindly don't forget to tag me, will really appreciate it.

I was wondering..
I came across this Forum group since I was looking for boot problems with my SM-N910T3
I hope flashing pit will resolve this..
I recently started to have some low level issue and was hoping it was partition/boot related and not hardware.
Randomly phone boot directly into Download mode with error;
ddi: mmc_read failed
Often I have to pull battery and hold down /power / home for 10 sec to boot up again.
Thanks
