[Q] frequent shut down - diagnosis & concluion. pls review - Nexus 5 Q&A, Help & Troubleshooting

Hi guys, here is my problem, diagnosis performed (thanks to other threads on this forum) and conclusion.
Looking for a peer review to make sure I'm on the right track and not missed anything.
Much appreciated
Issue:
random shut down during regular use
phone outside warranty.
Symptoms:
no warning, errors or app closure before shut down
always a hard shut down. no reboots.
will usually not power up again unless connected to charger
when it does power up without charger, it will almost immediately shut down again
irregular battery % display eg.
-before shut down will show 80%. On power up with charger, will show 55%.​-another eg. shut down at 80%. On power up without charger, will show 15% then immediately shut down again. On power up again (without charger) will show 65%​
phone unusable. max usage is prob 20min before shut down.
issue coincided with upgrade to Android Lollipop
no signs of overheating or 'lumps' in the back
Diagnosis:
assuming v5.0 upgrade being the cause, waited till v5.0.1 and ugpraded (Without factory reset). problem persists
factory reset to v5.0.1, problem persists.
flashed android kitkat using the image off the android dev site, problem persists.
visually checked power button for any signs of 'sticky button' syndrome but button look and operate as expected
running with most frequently recommended 'battery saving tips' applied
conclusion:
Faulty battery cell. looking to perform something like this: https://www.youtube.com/watch?v=VSGNUrpwIno

I assume that this solved the problem? Was it a difficult replacement/repair? I am having a very similar issue, except is it coincident with (and I'm unsure if caused by or not) an upgrade to Android M (6.0 and 6.0.1).

Changing the battery in incredibly easy in my opinion. I watched several different Youtube videos and, when I found the clearest one I could, I followed along with the video to disassemble my phone. Having the right tools will help a lot.

why my asus p525 shutdown every few mintues?

my asus power turn off and i need to turn on every hour
why?
my power save setting its not set.
Well,
- Have you changed the rom?
- This is a new device, or used?
- When do you recognized this problem?
- You got this problem when the device is on the charger?
- Maybe the device got some water, sweat, or vapor?
- Try to remove the battery for 1-2-3 hours, then put it back and try to full charge the batt.
- Try to do a ROM update, with an official ROM.
After this, tell if the problem is still.
lvikel2, hopefully you mean real shutdown - not the sleep mode. I write so because you mentioned power saving for some reason.... So let's talk about the situation when your battery is fully charged.
Prior flashing the device and removing battery for several hours you should check one little thing - a small switch hidden under the battery unit cover. The cover has a special flange which pushes the small switch when the cover is closed properly. If the flange is broken or the switch under it is not good - you will get spontaneous shutdowns.
i have the same problem. I tried putting a small paper in that small switch and it helped me for a month again its happening. whats the use of that switch anyway. can i take it off. Pls reply me at [email protected]
I had this problem too. My P525 works fine until few days ago ... i drop it(i think this is then it bagin) but everything else is working good it dont suspend etc.. so back to my problem a pice of paper on battery probably slov turn off problem but some times device go to sleep mode (like you if puch power buton).
i have this problem too, any solution?

Weird Fuze Power Button Issue

I have been experiencing a periodic problem where the screen on my Fuze will be on, and it will not dim or go to sleep. Even if I press the power button it does not shut off. So the screen stays on completely and will, of course, eventually wear the battery down. While this is happening, it is not frozen - I can still use TF3D. The only way to get the screen to go off is to do a soft reboot, after which it will perform normally (including the power booting working like it should). This happens about once a day.
This generally seems to happen when the phone is charging. When I unplug it, the bar at the top still shows the phone as connected to the power. I also notice that the battery seems a little warmer than usual at the times when charging causes this to happen.
In searching the forum I found one other user who had this issue, but did not see any fixes. Coincidentally or not, that other user was using Blackberry Connect, which I am also.
Anybody else have this problem? If so, any proposed solution?
While I am at it, I have a Blackberry Connect issue as well. The phone will periodically (usually, but not always, in the middle of the night) just stop receiving Blackberry Connect e-mails, even though everything in the Blackberry software looks normal. Again, I need to soft reboot to fix it. If anybody has experienced this or has a solution, it would be helpful also.
Thanks in advance.
my button seams to have quit working all together, soft reset doesnt help, tryed the hard reset mabe im,doing it wrong. it never ressets data basicly has the same efect as a soft reset.
not sure if its a hardware or software issue at this point. it randomly pops up the are you sure you want to quit txt.
Battory compleatly drained overnight, put it on chager and power button works again. No settings where lost that i see, kind of rules out a hardware issue.

[Q] Nabi 2 Reboot/Charging Problem

On my Nabi 2 I completed the OTA to 1.9.37, root, and gapps install - had the upgrading message on every boot but fixed that with the new gapps package (thanks a lot to all the great developers on this forum!)
However I still have a problem since the root process that I haven't seen addressed so far after searching the forums.
After my putting the Nabi 2 to sleep and plugging in the charger, it will fully charge and turn the battery light green as it should, shortly after that the device then powers off and requires a reboot/cold start vs. just a quick click of the power button to return from sleep mode. It does reboot fine and has a full charge - all other operations are normal.
Any suggestions on how to eliminate this power down/reboot after charging?
Thanks!
I've been having the same issue and have yet to find a solution. My sons Nabi already had the latest update so I just rooted it and then later did the Gapps fix to solve the constant "optimizing apps" issue. Now I've noticed the charging problem.
Just wanted to bump this thread as I have the same issue. I thought it was the hardware because I two tablets (one for each of my boys) with the same exact setup and only one exhibiting the problem.
I have noticed that I have to long press the power button twice, leading me to think that the device is on but unresponsive and I am turning off then back on to get it up and running...
I think my next step might be to completely restore to factory setup and see if it goes away...
On a side note anyone experience issues with fooz kids videos not loading??
Anyone has found a solution to this? I seem to have exactly the same issue. If i plug the charger in on a working system it freezes. Two times long press to do a reboot.
Mine lockup most times when plugging the charger in or leaving it charging on with screen off. Has done it since the beginning. There was a report that for it locking up while off turning the wi-fi off before hand helped. Otherwise I haven't seen a sure fire solution.

Galaxy s6 soft keys flashing

Hi guys,
My girlfriend has a galaxy s6 running marshmallow. The soft keys are constantly flashing/blinking whenever the screen is turned on. This also causes the device to lag, draining the battery.
I've tried factory resetting the device, and running it in safe mode suggesting it's not software related.
I also installed the the app "Galaxy button lights" that allows the control of the lights, this does stop them flashing, but the device still seems to be running slowly.
Thanks for any advice in advance.
Hi did you find a solution to this as I am having the same problem. Power mode on stops the constant flashing but the phone still lags and it flashes when I charge my phone. My power button also phantom presses :/
I have the same problem. Did you find a solution?
Me too. Turning off the buttons seems to help... it drives me less crazy... but it still feels like there is screen lag. I think this started after I installed the last system update.
One of my co-workers suggested that it may be caused by moisture inside the phone. I set it in the sun for a while, and the problem seems to have gone away.

This happened to me like 4 months ago, it hasn't "dried" till now However if i press hard on the lower left bezel - next to the app switcher button my phone works. I have a theory that the contact has become loose under the phone or so?
Hi, I have the same problem for a long time I installed a couple of firmware and the same thing on the factory software always happens, now I use custom rom and it works without problems, it means only on the factory versions I have a problem

Nexus 5 - Sleep of Death? Once going to deep sleep, phone dies.

Hi there,
I have been struggling with a problem the last few days, and have been reading quiet a lot. I got two old Nexus 5 phones, one had a broken screen, the other one had the display glitching problem - related to the flex cable. So I opened them and put a working one together out of both.
So far so good, everything seems to be working, with one exception: Once I press the power button, the screen goes black like its supposed to. If I wait long enough and try to wake the phone, its not responding. The only thing that helps is long-pressing the power button to hard reboot it.
So I did read a lot, about the power button malfunctioning and the batteries dying on the Nexus 5. I ruled out the power button problem and its working like it should. I ordered a new battery, which is not perfect, but has an estimated of 1800 mAh. I monitored the voltage of the battery with different apps, even logging them to see what happens right before the shutdown - but everything seems normal. So this could not be the problem either.
I am currently running the latest LineageOS, but I experienced the same problem running the latest factory image google released for the phone. I even tried different kernels. So I thought, it might not be software related. But since it always happened when the phone starts to enter the deep sleep , I tried to google some about this and found the SOD ( Sleep of Death ) problem for the Nexus 4. Since I was out of ideas, I installed an App called "SOD Killer", which creates a wake lock preventing the device from sleeping. Et voila - the problem is gone.
I could not find discussion on the internet relating to the nexus 5 concerning the sleep mode and the phone dying once it goes to sleep. Am I missing something here? The SOD Killer wake lock solution is a good temporary fix, but I would like to get to the grounds of this.
Does anyone have an idea what could be causing this strange behavior? Thank you in advance,
joha
What I forgot to mention is that once the phone is connected to a power source, the problem does not appear. That is also the reason why I wont get any logs via adb. ;p
I will try to get some logs with an APP and root once I get home - maybe there is some information about the problem causing this strange behavior.
I managed to get a log while the phone died when it wanted to activate sleep mode. But I am not that good in figuring out what in the log might be pointing in the direction of the failure. Any ideas?
I dont like the
Code:
09-21 12:11:51.977 E/BatteryStatsService( 786): no controller energy info supplied
parts in there. What might be the problem here?
Thank you so much in advance!
Does no one have any idea? I guess its hardware related somehow, when the phone tries to enter deep sleep. Anybody out there that knows, what the phone is actually doing when entering deep sleep which might be causing it to die / become unresponsive? Any idea is highly appreciated - I love that phone.
