Nexus 5 Random Shutdown Frequent Problem - Nexus 5 Q&A, Help & Troubleshooting

I don't understand how exactly can I explain the situation, but I'll be as specific as I can. Please try to understand and help me from this.
My Nexus 5 is on Marshmallow without any roots etc ever. Now, the problem goes like this:
Suppose I press power button once, then screen should turn on/off once. Now this which happens normally in any phone happens in mine for first few times, then it starts like if I press power button once to turn screen off, it goes from off and turns back on, I again press power button, again from on it goes off and back on, this keeps on happening until I try my luck for it to off, but then sometimes it happens like after so much pressing it eventually show me "power off" option on screen(which generally should open if I hold the power button). Now once I encounter this "power off", no matter what I do, I power off/not, it'll automatically turn off, and this happened atleast 10+ times till date. So finally whenever I encounter "power off" option, which sometimes comes when I try to turn screen on or sometimes off, but never I hold the power button, but finally even If I don't click on power off, it'll power off.
And that isn't yet strange till there, normally now "Google" shows on screen when device is powered on, but here after encountering "power off" it shows "Google" and turns off.
This problem has happened to me from maybe starting a week ago, atfirst I ruled it as maybe hardware problem, cause after 3 factory resets, nothing changed, but then when I did wipe system cache and data format from recovery screen, everything got resolved. But this too remained for 2-3 days, again same problem started after it, I this time cleared system cache from recovery, and this time too it helped somewhat. so I can atleast say that it isn't a hardware power button problem, but something which I don't know what, always creating problems from software.
Now this problem has developed itself, because now the power button is kinda working okay, but now the "power off" comes on screen automatically, I can say once-twice a day, and as explained 'n' times before, once I encounter this, mobile turns off.
So everytime I've to turn phone on after this, and pray that it doesn't repeat, but it's yet going on, and i'm so pissed off by this phone, I regret buying this, honestly as till now mentioned I tried whatever I could/I knew, but nothing, nothing's helping me.
Also the problem intensifies when phone is on charge & "power off" is encountered, then the phone goes to turning off and "Google" is shown, then it shows "Google" then turns off, then it shows "Google" then turns off, and this loop keeps on going.
Finally I hope i'm as clear as possible, if someone can please help, I can guarantee any kind of format will just resolve the problem for few days only, and hardware power button problem i'm not feeling it as formats basically help it great, but anyway if I'm going wrong somewhere/need proper explanation somewhere then please tell but resolve this asap.
Phone's from India and it's been 1 year since bought and atleast a month from the Marshmallow OTA update and this problem started randomly without me doing anything I guess from a week ago.

I think you should take a look at that power button.

It's your battery. I was having the same problem with my nexus, I replaced the battery and the reboots are gone.

Mine did this exact thing a couple of weeks ago. really annoying and couldn't put my finger on it, until i got so annoyed that when it came up with the power off notification I repeatedly pressed the power button for maybe 20 times, this resolved it for a few days, though to be honest, the best advice that someone posted, was that a sharp shock to the side of the phone that the button is on resolved it, been over a week now and it's been fine.
I put it down to the case i had on it, harbouring small dirt that was getting into the button housing and interfering.
try it out, failing that, perhaps a new power button, i did have one in my ebay basket, though i don't need to go down that route, not for the foreseeable anyway.
**edit
incidentally, i went down the software route too wiping caches etc. no avail.

broken fuze. powers on as soon as battery is popped in

So I've had my fuze a little over a year now, no major issues. Used mostly energyroms, but about December time I switched back to a simple non-bloated stock rom for the stability.
Anyway today at work I was texting, and I press the power button to put the phone in standby. And the screen remains on and usable. I tried again and it would not go into standby (power button physically feels normal, it does not feel loose or abnormal.) So i let it sit for a few minutes, then i look at it and a message poped up asking if i wanted to turn the phone off (like as if i was holding the power button)so i press no, then it comes up again a few seconds later and aagain and again. So I soft reset the phone.
The phone resets but takes a LOT longer at the att/htc splashscreen, then it hangs at the htc screen and does not make it to the wimo screen, but instead an error screen saying:
"The device is unable to boot because you have either turned off the device incorrectly or tried to install an applicationa from an untrusted source, press SEND to reset your device or press any other button to cancel..."
I think it went through the hard reset this time because when it restarted it asked to calibrate the screen and install stuff. it resets again sometime after that, still takes forever at the splash screen and comes back up to the error, only this time no matter what button i press it wont go away and boot into wimo. It seems like none of my buttons work (they wont light up now) when i slide out the keyboard, it is not lit up like normally.
And heres the kicker, my only way to turn on/off the phone is to take out/put in the battery. As soon as I pop the battery back in the fuze turns on. Is my phone toast? Ive tried to hard reset and the phone does not reach the bootloader, it goes straight to the splash screen. Same with trying to reflash it from my comp, raphealwrapper cannot find my phone.
I've only recently encountered the exact same problem on my Touch Pro, but stock ROM and everything. As far as I can tell, our power buttons are busted and probably need to be serviced. One of the contacts must be stuck in the 'on' position somewhere inside :\ As a temporary fix, I've been using AEButton Plus and remapped double tap end call key to turn the screen off, and removing the stylus to turn it on.

[Q] Screen won't turn on/can't boot

I think my problems began when I installed the OTA 4.2 update recently. The entire system bogged down and became pretty much unusuable. Often, I had to press the power button 3-4 times to turn on the screen if the screen timed out. Sometimes I would have to wait for at least 5 minutes before I could wake the screen again.
But since a week, I can't get my Transformer Infinity to wake up, at all. When I press the power button nothing happens. If I hold it for a long period of time (10 seconds) it gives a short buzz, but nothing visible happens otherwise.
I have tried pretty much everything I can imagine now. I have even tried to drain the battery completely (then absolutely nothing happens when I press the power button) and re-charge the device, but the problem persists. I have tried to start it connected to the keyboard dock and without, but for no reason.
Connecting the TF to a desktop computer doesn't seem to do anything either.
Please, can anyone give me a hint?

Sorry, but I think it's time to call Asus Tech support for an RMA.

Hmm i often have he issue with needed to press the power button a few times to wake the screen. Just thought it was 'one of those things' hope this doesn't happen.

Actually, I have had that problem for months, and I thought it was "on of those things" too, but it instantly got worse after my 4.2 update. Up until last week when it just stopped turning on again all of a sudden.
I have also tried plugging the MicroHDMI to a larger screen, but the screen just complains that there is no signal in the HDMI cable.
I have contacted my local ASUS support in a vain hope they can direct me at a solution that doesn't involve me loosing my device for a lengthy period of time and getting it back without my precious (un-backuped:crying vacation photos.

A lesson learn, I always keep all my stuff on sdcard, never on internal storage.
Same Problem Here
I just got my tf700t April 17, and I used it for a few days and did the updates before going on vacation for a week. After a few days on vacation, I noticed the volume rocker wasn't responding all the time. I tried to restart the tablet, and once it shut off, it never came back on. Same issues as original post... Screen doesn't turn on. If I hold the power button down for 10 seconds it vibrates, but nothing happens. Very upset to spend this kind of money on a tablet to not even be able to use it for a week. I will be sending it in for RMA... I have tried everything in every post to try and fix the problem, but the screen just doesn't want to turn on. Hope Asus will be quick about it!!!

[Q] Bootloop when power button sometimes pressed

Hi everyone!
I think my bootloop problem may be a unique one because it only occurs whenever I press the power button (and I've kinda searched other threads and couldn't find a bootloop issue like mine). But before I explain in depth, here are my specs:
Stock 4.4.4 rom
Rooted, with xposed + gb
ElementalX 1.00 kernel
This problem is a randomly occurring one; when my phone is fine and I press the power button, it almost usually goes into a bootloop. It can either stay on the google screen or last all the way up to the x-boot one. Sometimes from the x-boot screen, it'll reboot again. So I realized that if I randomly press the power button a few times (usually trial and error), the problem goes away sometimes and I boot normally again. However, if I hit the power button again for any reason, the bootloop issue relapses.
Also another thing to note is sometimes when my phone is switched on and operating normally and I press the button, it doesn't always reboot immediately. Sometimes it behaves as if the power button is held down and the power menu pops up in the lockscreen... then subsequently it boot loops.
So I'm not sure if this is a hardware issue to do with the button itself (because I very rarely ever drop my phone. Perhaps about 3 times in the past 8-9 months since Dec 2013?) or it's a software issue...which will mean I've to reflash my stock rom.
Anyone with a similar issue please help! It's kinda driving me nuts cos I can't even unlock my phone without triggering a bootloop...:crying:

Might want to send it in for repair. Mine had the same symptoms about a month ago--spontaneously displaying the power menu, boot loops where I'd need to do a hardware reboot (or whatever it's called, vol up + power) and sometimes it won't wake the screen when I press the power button and act as if I turned it off. Tried to reflash recovery and change roms, same banana. Then suddenly it won't go out of bootloop, sometimes gets to the x-boot and sometimes only until the Google logo. Sent it for repair and lo and behold, hardware problem. I think this is really inherent on some older Nexus 5's with the wobbly power button.
I suggest you do a nandroid backup while you have the chance. Never had a chance myself

sigh, i reflashed stock rom and the problem persisted. i can't even stay on the bootloader screen without it rebooting itself all over again. i guess it's an old nexus 5 hardware problem like you said :/ thanks for sharing!

Sounds like the power button is getting stuck, or shorting out.

[HELP] Unrooted Nexus 5 randomly shut off, now frozen on Google logo at startup

I didn't drop it or get it wet or anything, it was just sitting on my desk and it randomly shut off. I've tried shutting it off and on again but it just comes back to the google screen where it sits frozen for about 30ish+ minutes before it shuts off, I can't turn it off otherwise, if I try turning it off it just turns itself back on so I can't shut it off. Is there anything I can do to save my data (or even better, fix my phone) or am I screwed? I also don't have USB Debugging turned on so I can't get stuff back that way either. My phone is not rooted and running stock android 5.1.? (Don't remember my exact version but I think I've missed the last 2 minor updates)

I has an issue with it a few months ago with the power button but it was stuck in a constant bootloop (I later found out that the power button was physically stuck, and a few hard flicks fixed it) , now it's just frozen on the google logo for 30-40ish minutes and then it shuts off by itself. Could that still be an issue with the power button?

Yeah, my LG warranty expired so I found a seller on eBay doing it for 25$ (replacing the switch inside)

I'm kinda confused on how this is the power button. On a working Nexus 5, if you hold the power button down the phone just continually resets, now it freezes on bootup and doesn't shut off for a really long time. Then after it shuts off, you have to manually turn it back on (then it just freezes again). I feel like this is could be a software issue but I might be wrong.
I've seen posts saying to reset the cache partition. Will that wipe the data on my phone?
I went into recovery mode (Does this mean the power button is fine, since I could successfully navigate the boot menu) and tried to format the cache and it says it was wiping /cache for about 20 minutes then it shut off and the notification light started blinking red and the phone wouldn't turn on at all when I held the power button. I assumed this meant the battery died during the cache wipe (Is that what the red light means, if so is that bad?) so I plugged the phone in. After about 30 seconds I could turn it on again, but it just holds at the google screen again. I'm really starting to freak out as I have some unbacked up data. Even if I can't fix the phone, is there any way I could save the data? I have a locked bootloader and USB debugging is turned off (Yes, I'm an idiot).
It does sound like a faulty power button. Since it's very cheap to fix, I would first find a local lab to change the button. At least rule out that..
If you can't fix the phone, you cannot get the data.
Also, be carful with bootloader and adb, so you don"t accidentaly erase your data.

The nearest phone-repair shop is like 45 minutes to an hour away from me so I want to be sure this is it. How exactly would a faulty power button cause this to happen? The phone isn't acting like the power button is permanently held down or not held down at all and I was able to get through the boot menu to the clear cache partition menu which requires use of the power button (And has the shut-off and blinking red light interrupting the cache clear made things worse), all that seems to be happening is the phone freezes during boot-up.

This sentence points all fingers at the power button
"I've tried shutting it off and on again but it just comes back to the google screen where it sits frozen for about 30ish+ minutes before it shuts off, I can't turn it off otherwise, if I try turning it off it just turns itself back on so I can't shut it off"
If you turn it off and it comes back on. it's the power button
Some symptoms of a faulty power button
If your LG Nexus 5 keeps rebooting for no reason to the Google Logo only
you cannot lock the screen
screen locks on its own
phone turns off for no reason during regular use
Lock/power Button is VERY sensitive to touch

The power button is not dead, it's faulty, and behaves erratically. Sometimes it works, sometimes it does not. It's an educated guess. If you put in a lab, and it's not the power button, perhaps they will know what else could be wrong. It's your call.
Just got back from the repair shop, it's not the power button, it's some unknown software issue. They can't fix it. Anyone have any ideas?
This is very odd. I am not aware of any software issue that can prevent a physical shutdown of a phone. Was this a reputable lab?

The phone shut itself off after a period of time, but holding the power button just restarts it. They replaced the power button just to be sure and it didn't fix it.
When you connect the phone to a PC does it show up? Can you copy your data? If not, I don't think you can save the data.
One more thought: If you put the phone in bootloader state, does it still shut down or restart by itself?
I just talked to the phone repair people and they said they just found out it's not software, a circuit in the motherboard got fried and they only way they could fix the phone would be to swap out the motherboard.
That is a 200$ reapair. Before you do that or give up on your phone try my guide here http://forum.xda-developers.com/google-nexus-5/help/nexus-5-stuck-boot-loop-lollipop-t3098632
I had a different problem but was also told by the local LG lab that it was the motherboard. It wasn't,
If my guide does not help, it probably is a hardware issue. See if the lab has an insurance deal. Over here they suggested to sell me a one year insurance for 150$ , and change the motherboard. That would have saved me 50$....

I think my power button assassinated itself

So heres the situation. I woke up, and tried to press the power button once, which i do to get it to show the lock screen, that didnt work so I hit the home button and didnt think anything of it. Eventually it occured to me thats not normal, so I tried holding the power button to see if the reboot options would pop up, and again nothing. So without thinking I took the battery out, put it back in, and as Im sure you can guess, nothing. The phone is rooted and has TeamWin recovery, but I did that the same day the Marshmallow update was available, so its been working fine for weeks, then all of the sudden this happens. Im 100% positive its nothing I did rooting the phone weeks ago, I just wanted to eliminate that as a possibility.
So as it stands, my phone is off, adb wont recognize it while its off, so rebooting into recovery that way isnt a option, getting into recovery pressing the hard keys isnt a option. Anyone else had this issue, or know of a quick fix solution? Im open to anything, that doesnt require taking the phone apart. Because I dont want to, because I hate going there, but Ill take the phone to sprint if I have to.
Also, when its plugged in it shows the charging screen.
In short, its not bricked, its not stuck in a bootloop, basically, is there a way to turn it on, aside from the power button?
Any and all help is appreciated, and thanks in advance.
I actually just got it to turn back on, then I was hit with a constant "Unfortunately NetworkSystemProvider has stopped" and its 4am, I dont feel like messing with this, so I did a factory reset, and if this doesnt work Im either going to throw it off a overpass, or just turn it back off and wait to take it to sprint, because if I had a hard time getting it to turn on Im sure they will to.
