HD Turns Off/On at Random Times

Hi all,
This seems a rather frustrating way to announce yourself to a community (other than to Fallen Spartan - thanks again for your help) but I need some help. The problem:
A couple of days ago my phone started to turn itself on and off at random points. It will bring up the 'Do you want to turn your phone off YES/NO screen' and even if I say no it will reappear until I say YES. This also cause the hard on/off button to stop functioning. I have been rectifying it by pulling the battery out, putting it back in, letting it turn itself back on (note turning ITSELF back on), letting it boot up, from which I can turn it off. Leave it for a min and then turn it on again. As you can imagine however this is a painful process and one I'd rather avoid on a daily basis.
I have noticed a bit of a pattern and this error often occurs in the morning after taking my phone off charge (I leave it charging overnight). In addition I haven't installed anything in the last 48 hours (the start of the issue) other than the media player mentioned here;
forum.xda-developers.com/showthread.php?p=3248642#post3248642
and the new Dusk Theme....however it was doing it before this was even downloaded.
Anyone else experienced this and more to the to the point has anyone fixed it?
Thanks

No one....?

I had my phone in my pocket while jogging in the rain. The phone didn't get really wet, but from then on the power button is now "stuck". The button is permanently pushed in. (The button appears normal, but the contact inside the phone seems to be stuck closed).
The result is that the phone acts like I'm always holding the power button down. Here's what now happens:
- when I insert the battery, the phone automatically powers up
- when the phone finishes rebooting, the PowerOffWarning.exe application crashes (this is the app that runs when you hold the power button down for a second and you get the Power Down options/Slide2Shutdown (shut/restart etc.)
- battery life is drastically short - the phone runs on a full charge for maybe 3 hours, because the power button is constantly sending interrupts to the phone's CPU which in turn can thus never go into low power mode
- battery drains totally. Normally, when the battery gets low, the phone shuts down. Since the power button is pushed in, the phone is forced to wake up, using a bit of the remaining battery, but then shuts down since the battery's too low. This repeats until the battery is so dead that the phone can't actually power up enough to start the power up sequence.
- the phone constantly reboots when on a charger after the battery has been completely drained. Since the battery is so dead, when it's plugged in to a charger, the phone has enough juice to reboot, but during the power-on sequence the screen turns on which uses too much power, and the phone shuts down. This repeats until the battery has enough charge to handle this big load. It takes 5 minutes of constant rebooting before it charges enough.
I took the phone apart and examined the switch but I couldn't fix it. The circuit is available on eBay but it's really expensive (USD$140 I think).

@GreedyFly
Have you tried the basics like a hard reset or re-flashing a rom?

THIS!
This is a very similar, though slightly more extreme version of what is happening to mine.
@Stuntdouble yes I have I am afraid I have and played with various tweaks.
Any ideas if connector cleaner (something like Servisol) would sort out the connections or is it more likely to harm?

I have an almost identical problem after water "damage" Did anyone come up with a fix/repair???

the fix is to take the thing apart, to the point where you remove the power button PCB, and CO Contact Cleaner the hell out of it, press it while its detached a bunch of times (when i say detached, its still connected to the main ribbon but not clipped into the housing), clean the physical button plastics, and slap it all back together.
theres a picture of the power button circuit board out of the housing in the bottom link of my sig.

Brand new Galaxy SII, stuck on "empty battery screen"

Hello,
Just got my SGS2, I played with it for about 10 minutes and the battery died.
I figured it would because it was new and I hadnt charged it yet, so no big deal.
Then I plug it in.
For the last 45 minutes, it has been flashing this screen then going black.
I can't do anything

Return it and get it replaced.

There is literally no fix for this?

I wouldn't know, but no new phone is supposed to act like that.

Have you tried pulling the battery or booting into recovery? Also try another usb cable or wall outlet, maybe it's not getting a charge. Make sure the usb port is clean. I'm sorry but I don't have a definitive solution.

I had the same issue after 2 weeks of use when i was on a business trip!!!. I left the phone plugged in overnight and it charged. As far as i remember id displayed full charge next day but actually it was not fully charged (i guess it was about 20%). So after a couple of recharge cycles it worked ok.

I just had this happen today on my ATT Galaxy S II. But what happened was I let the battery almost drain and I had a brand new oem battery that I had charging over night. So with the old battery in I rebooted into recovery wiped battery stats and powered off. I then put the new battery in and when I plugged it in it was stuck at this screen. It seems to be charging though and how you can bypass it is unplug it and just hold the power button down for like 10 seconds it will reboot.
But the question is.. will it go back to normal and show that it's actually charging for everyone? or did some get stuck for good? Since the thread is old I'm sure you guys have either gotten yours replaced or after a while it just started working normally again. So I'm curious on how to fix it. It's happening with both batteries on this phone now but work fine in another phone

May be let it charge and then calibrate your battery

Had the exact same issue when I bought mine... Turned out I had not plugged the battery correctly. Just try removing the battery and put it back.

I got it working again. I think thee might be a bug with CWM or CM when you wipe battery stats/recreates them. I restored to the bone stock rom and the icon started animating again. I restored CM 7 which was the version I wiped the bat stats and it stopped working again. I then just reflashed CM on top and it started working again go figure Thanks guys

I had faced that problem too.Just try plugging out and in the battery and start the phone.Make sure the battery is fixed into it's place.If it is still not working,continue the plug-out and in the battery and start the phone again.Try it for several times.It will work.When i was in that situation,i thought mine was BRICK.Hopefully replugging the battery fixed this problem.
Another situation is when i plug in a fully charged battery,it only shows 60 percent after booting.After replugging the battery,it just got right back to 99.

Good stuff - when I bought my phone, the first charge took so long.
Is it true that the wall charger charges the phone faster than the USB charger? (just something I have noticed).
Thanks

[FIX COMPILATION] RED LED: All 4 Scenarios - All 4 Fixes

Now i know this thread is a little repetitive but this thread covers the red led problem in detail and also covers various scenarios of red led.
I very recently had a red led situation and had to scourge through various threads to find a solution and every thread covers a different solution.
I Have merely scourged, understood compiled and explained in detail all the problems related to nexus 4 Dying out and their solution. All the credits go to every person who originally provided these solutions in their threads (a lot many )
RED LED: All 4 SCENARIOS - All 4 FIXES
Just Follow the steps and you will be up and running with your phone in no time
Description: What happened was, you were merrily spending some beautiful moments with your phone but suddenly, the phone died and the red led started blinking and you felt like your world came crashing down. Then you attempt to restart you phone but nothing happens and the red led blinks again...even stops blinking after sometime, and now you feel that the time of your nexus 4 has come.But fret not... read on.. and you will be reunited with you living and fire breathing nexus 4:laugh:​
SCENARIO 1:RED LED (OR NO LED)- LOW CHARGE
What actually happened: The battery drained completely (below a threshold level).This is different than normal discharge to empty and any attempt to reboot the phone results in the red led blinking or nothing at all indicating the battery is extremely drained.​Why it happened: Its a fault from LG. The Battery Calibration circuitry or logic is a little messed up allowing the battery to discharge below a threshold and then stopping the discharging rather than stopping it before.​Solution: Well this is the most non-worrying scenario to come out of. You simply pop-in the wall charger to the phone to allow it to charge. Initially red led will blink and after some time the charging indicator comes up on the screen. It may also happen that once you connect the charger, red led will not blink. Don't worry keep the charger connected. Ultimately the red led will blink and then charging indicator comes up(red led blinking may be skipped). Let it charge for a minimum of 20 minutes allowing the battery to charge about 15% before attempting to turn on your phone, other wise the phone may be stuck on the google logo while starting up.then charge the battery to full capacity and you are good to go.​
SCENARIO 2:RED LED (OR NO LED)- BATTERY CUTOFF
What actually happened:Again the battery drained below a threshold OR due to the messed up battery callibration and the phone circuitry cuts off the battery even when the battery has some charge left.​Why it happened::Fault at LG's side. Bad battery calibration implementation.​Solution:A Slightly Difficult but only solution is to disconnect the battery. You do this by opening up the back and only disconnecting the battery connector for about 1 minute..this resets the battery cut-off then connect it again..put on the back.. charge for minimum 20 minutes.. the battery charging indication should come up on the screen, let the battery charge fully and you are good to go. Search on google for nexus 4 disassembly videos to know how to disassemble the nexus 4.You just need to open the back(the most detailed disassembly video is from "LE55ONS" on youtube). Be cautious while opening the back by not applying too much force or pressure.​
SCENARIO 3:RED LED(OR NO LED) - BATTERY DISCHARGE AND CUTOFF
What actually happened: Again the battery drained below a threshold AND due to the messed up battery calibration and the phone circuitry ALSO cuts off the battery.This Scenario is a combination of of Scenario 1 and Scenario 2.​Why it happened:: Again the blame goes to LG's Bad battery calibration implementation.
Solution: A little more complex than the previous solution.You have to open the back and charge the battery externally. Just open the back, disconnect the battery connector. Now rip apart a micro usb cable and connect(use tape) the red wire to the +ve terminal and black wire to the -ve terminal.

then charge the battery with the original wall charger for not more than 10 minutes!.
then connect the battery back to the phone and now charge the battery via phone to the full capacity. and you are done​NOTE! Remember! since you are charging the battery externally, there is no charging circuitry involved to stop the charging when the battery is full.and you just need the amount of power required to boot up the phone. charging the battery externally for 10 minutes should charge the battery about 5-8% which is very much enough to boot up the phone. I WOULD SUGGEST FOLLOWING THE ALTERNATE METHOD BELOW
Alternatively, if you are a little paranoid over electricals like me, you can trickle charge the battery, means, instead of using the original wall charger that outputs 5v @ 1A, you can use old mobile chargers that usually output 5v @ 100mA. upto 250mA is fine. this way you can and have to externally charge the battery longer(without causing damage to battery) to regain 5-8%.
This solution was originally provided by http://forum.xda-developers.com/showthread.php?t=2250454&highlight=red+led Big thanks!​
SCENARIO 3:NO RED LED, CANNOT CHARGE, AND YOU HAVE TRIED ALL THE ABOVE SOLUTION
What actually happened:: Faulty unit
Why it happened: Manufacturing defect.
Solution: Unfortunately, you will have to RMA your device
***************That was all the causes of the red led and their solution.. hit Thanks if this helped or you found it helpful *******************
Cheers and wish you a happy life ahead with your beloved Nexus 4 :fingers-crossed:

reserved

Great!
Thank you so much.
But i wonder why it happens. The battery was at 85% whe the mobile suddenly went off then the red led thing happen.
It happens every month and dont know why.
Thanks for your excellent post. :good: :good:

[Q] Battery indication weirdness

Help!!!!!!!!!
I charged my Nexus 7 2012 32gb yesterday morning, and took it off charge in the afternoon. I lightly used it in the evening, and it probably went to bed on ~60-70% charge. My alarm went off as usual at 07:00 this morning, and as far as I can remember, when it woke me up with that alarm the indicator in the top right was in roughly the right position for ~60-70% charge. Come back to it 5 minutes later after getting dressed, I tried to dab the power button to wake it up. That failed. I tried holding it down, trying to turn it on (it randomly turns itself off at times, for the record, so I suspected that). That also failed. I plugged it in to the charger, and it displayed a black screen with the occasional fuzzy rainbow line flickering on the screen.
In absolute panic, I googled this on my phone, and everybody recommended to take it back to PC World, apart from this one person, somewhere, suggesting to unplug it, leave it alone for a while, and try to turn it on then.
So I did that. I waited half an hour, and tried to turn it on. It successfully worked, apart from the fact that it suggested to me it had 0% charge, which is frankly impossible. Nonetheless I plugged it in, and the battery interface in Settings seems to be doing all kinds of weird things. For starters, I've charged it for half an hour, and it still is on 0%.

The first photo shows it on its lock screen, plugged in. Note it asks for me to plug it in a charger, but in the top right it alleges that it is plugged in, due to the lightning bolt. Weird.
Take picture 2. 0% charge, same as what the notification drop down says. Then "Unknown". Wonderful. Normally,that should say charging, or not charging. But "Unknown"? That doesn't sound good.
Then picture 3. The battery usage graph. My understanding is that batteries discharge on a gradient, often a steep one, but not exactly the cliff drop here.
What on earth is going on, and do I really need to take it back to PC World, or can it be fixed?

EDIT
I've got advice elsewhere and my fix was simply turning the device off, power cable out, then booting it to the Android Bootloader. From there I selected the shutdown option using the volume and power keys, and waited till I was sure it had shutdown. With the off device, I plugged in the power cable, and then turned it on normally. Problem solved.

Nexus 4 Not powering on at all. Battery dead or phone dead?

Hello. Recently I decided to pick up my old Nexus 4 again and try seeing what happened to it.
I was using my Nexus 4 one day and dropped it from my bed, about a foot or so, and it just cut out.
I opened it up to find out that the battery cable had snapped because I had done an earlier battery repair, and forgot that I should have let the cable slack a little bit.
A few months later I get a replacement battery, and tried booting on the phone. It would get to the lock screen and say the phone is critically low, and shut off.
TWRP said the battery was at 80% charge, but the UI was flickering a bit. I asked the XDA Discord and was told it was a storage failure.
A few more months pass by to now, and I decide to try and revive my N4. I want to see if maybe the battery was seated wrong, it could've been.
I reseated the battery and tried plugging in the phone. Now, I get a solid red light, that changes to flashing, and then nothing. or a flashing light that stays flashing.
I have not gotten past this. Is the battery toast, or is the phone toast? Can I test the phone without buying another replacement battery? Thanks.

You can try getting a V+ measurement from the battery to get an idea of it's condition.
If it won't charge it's cable or connectors may be damaged.
Even if the battery failed it should take some charge. Obviously it's producing some voltage but maybe not enough to boot.
If the battery seems to take a charge allow it the charge overnight and see what it's voltage level is. If it still won't boot it's either the battery or hardware damage, but doing this would give you more information to make a call.

I've left it on the charger multiple times, and the phone seemingly doesn't do anything. never gets warm. I tighened down the connector screws and am using a cable I know works. I'll try to get a measurement from the battery.

Check the other ribbon cables, port jack/pcb, mobo etc. carefully for damage or looseness.

UPDATE:
I was able to get the phone booting, but now when i try and start android it immediately says "Power Off" "Shutting Down"
now what? bad battery? it's plugged in, it shouldn't do that.

May be the battery as it may draw quit a bit of current when booting.
More than the charger may be able to sink.

Yeah try that. Eliminate the cheap possibilities first. Seems like a battery or power issue.

well that might explain it

Yay!

Phones working, forgot to say this on Monday. Although the battery percentage is fluctuating after charging overnight under LOS 15 and 17, no clue why.

New battery's dead. I'll try and get another.

I know this thread's old, but i'll just update my results with this:
She's cooked.
I got the new battery, worked fine for a bit, but the battery percentage was completely jank and would go up and down. Not too long later, it doesn't even boot. I'm guessing the EMMCs fried. If I find a smashed up Nexus 4 locally i'll for sure do a mobo swap since mine's in really good shape physically.
