How to do a "battery pull" - Nexus 4 Q&A, Help & Troubleshooting

Clearly we can't do a battery pull on the N4, however that always seemed to solve a lot of issues on my previous phones. Even restarting the phone doesn't have the same effect. Is there any way to simulate a battery pull, either via an app or some other method?

Hold the power button for about 15 seconds.

Pressing/holding the power button for 10 seconds until the phone reboots is entirely equal to a battery pull.

Thanks, I tried that and I assume it worked.

[Q] Any crash log?

I'm using G2 for two month. It's crashed like 5 times.
It's like when I try to wake it with power button, no response.
Opening keyboard, nothing.
So I first thought the battery ran out somehow. Connected to charger, no light.
I thought it's totally dead. but found if i once take off the battery and return it then press power, it turns on.
I wonder if it's hardware or some app causing this.
any way to diagnose?
Use Logcat from ADB.

Long Press to Power On?

Anyone else have an issue with having to long press the power button 20+sec after powering down for more than a few minutes to get it to turn on?
Just returned an 8gb unit for screen lift and wanting a bigger storage capacity. Know its hard to get a perfect unit and I have found a perfect screen but now every time I power down I have to long press the power button to turn it on. My other unit turned on within a few seconds. Normal?
I've had that happen on 3 of them already. I've just learned accept it as normal behavior. Some days it powers on quickly some days i have to power it by holding the power button for 20 seconds.

How often do you power down your device? I probably never, unless have to.
Btw, I don't need ours the button for that long
Every Android device I have had expects a long press to power on.
Nexus 7 is one of the faster - mine takes about 4 seconds.
I expect the delay is to keep a momentary press from accidentally turning it on (pocket call).
I was panicked yesterday. After powered down, I could not turned it on.
Usually it will take a few seconds, but yesterday was about 20 seconds.
So I guess it is "normal".
I will no longer freaking out next time

Happens to me too. Every time it takes about 10-20 secs to power on. Generally I switch it off at night!
Yes there are times when I just press for 2-3 seconds and its powers up. Sometimes, it just doesn't power up even after 10 second... But I got used to this issue and I just keep trying again and again.
This is something Google should fix

Just bought one today and have this issue, about 10-15 seconds. Weird randomness. The first boot it only needed a few seconds. When you're travelling like I am atm its good to be able to power off if i dont know when i can charge it the next time. I wonder if its hardware or software. Nice device anyhow, the screen is so so but at this price i wouldnt expect better.

I had the same issue and thought my battery died, but the weird part is if I plug it into the oem charger it wouldn't show anything either. Don't know if that's normal or not.

Same here, I purchased it, held the power for a few seconds to power it on and it worked. After a few days I decided to turn it on one day and it wouldn't power on til I googled the answer LOL
mine booted up super quick at first, started loading it up with apps, and after my 2nd full battery discharge i noticed that it took 10-20 seconds to turn on. i have a C8OK, very very slight left side lift (not enough to be a bother) and i had super minor flicker at low levels of brightness. Funny thing, i got LUX brightness app with the free 25$ and use the "sub zero" brightness setting, i like to save battery and keep it dim, this has eliminated ALL flicker for me. i was thinking it was hardware doing this as other tegra devices had flicker, but now i think it is something with droid settings/software. i would suggest all those with flicker to try this app.

Are you talking about boot up time or time it takes holding the power button before the device switches on
For switching on it should only ever maximum take 10-15secs of holding power as holding power for 10secs simulates a battery pull

[Q] Won't switch on....

So, my phone ran out for battery and died. Plugged it in over an hour ago, but the phone will not switch on. Anything I can do?

Nope!
Something similar happened a couple of days ago. Held the power button for around 10 seconds and a red notification light came on. I think it was flashing as well. About 10 or so minutes later the screen came on. This time the phone is just dead...
Have you tried any button combos like- power + volume up + volume down.
Also did the phone run out of battery normally or was there any battery drain?
This doesn't look good for n4.
Hold power and vol +/- to enter recovery mode and then restart.
But before make sure ur charger or outlet works.

None of the combos work. It's as if it's not charging...
Weird. Plugged it into my laptop to check if that worked. Nothing. Plugged it back to the mains and a red notification light started flashing. After about a minute the screen came on with the battery animation. I managed to switch the phone on now. The wallpaper was reset to the stock one, but everything else seems to be fine.

Red Notification light. Phone won't boot up

I ran antutu benchmark and the phone automatically rebooted. I ran it again, and got forced closed. Now It won't boot up. On charging it, the charging symbol appears followed by the red notification led. On booting while charging, I can go uptill the google screen but not further or bootloader mode. Please help!
It is rooted with cwm and faux kernel and Dalvik and Bionic optimized libs

In all honesty, you were probably right there, but you just didn't let it charge enough. I had a rlod the other day, I must've done it good this time because I had to let it charge for almost an hour before it would power back up. I can't remember though, if it actually chargers when the red light is lit, or if you need to unplug it and plug it back in so that it's plugged in with no red light, no power on, or anything. Let it charge while of with the red light on for about 20 mins. Then fiddle with it, unplugging and plugging back in, until you can get it to stay plugged in without powering it up or the red light coming on. Let it charge for about 20 mins like this too. Unplug it. Turn it on. Plug it back in immediately after seeing the google logo, let it finish booting and finish charging and you should be good. I've had around 5 - 7 rlod (mostly all my fault) and this method has worked every single time. I've never opened or rma'd my phone.

I'll try this tomorrow as it's 1 30 am here and I have a test tomorrow. Let's hope it works..
Btw I should mention, when I connected it to my pc, i got 'installing device driver' message with 'unidentified device' I mean is the phone already on? (although fastboot devices or adb devices doesn't show anything)
Thanks!
Sheep.... If its instaling drivrr on rlod then 49% of your phone being stuck at QHUSB_DLOAD mode. Good luck

What's QHUSB_DLOAD mode?
If the phone is completely powered off, your computer shouldn't even know when you plug it in, it shouldn't pop up with any messages at all. What your getting sounds a bit like the message people get when their phone is hard bricked, except reading from your first post, you havent done anything at all to even get close to a hard brick. Try holding your power button for 30 seconds. A real 30 seconds, count it out. When I turn my phone back on from the rlod (after doing all my rlod steps in the previous post), sometimes I have to hold the power button for a god awful long time, it has to be close to a full minute. Your phone might be frozen on some lower level (locked up bootloader maybe?) and might require holding the power button that long as well.

Its Mike Download mode for Samsung devices.its trigered by the 2nd bootloader when the 1st onde fails to boot.when on this mode.the nand turns into a pendrive(like) and can be all reformated(re send partition table).but we dont have all the files to do that.

Btw, would leaving it charging for about 5 hours cause any further damage? I mean is it advisable to do so?

Wish I had a four letter response. Was this after letting the phone charge? I would power off and let it charge until you wake up. (four letter word was in reference to QLOD and RLOD like the average layperson would know what that means! )

I'm thinking a hw or battery issue. It's strange (duh) that after that length of time that it would shutdown after disconnecting the cable.

I hope I don't have to open it up. Its nearly 3 here so im leaving it charging and will remove it in three hours. Will get back later.
Thanks!
So nothing worked.. I guess the only way left is to open the phone up.. Wanted to avoid doing that at all costs :/

Well i have been writing about this. In short you have to disconect the battery, and try to boot it again.fist try to hold the volume down when conecting the charger, it will restart bootloader , select to start. f that doesnt work, you have to disconect the battery, and wrtie an factory image ( nexus 4 occam ) . Try to boot the phone first when disconecting the battery, before writing the factory img. GL

Nexus 10 Frozen

Hello, I have a problem with my nexus 10, it froze on me with around 40% of battery left.
I can't turn it off with power button, nothing responds, so how can I turn it off and restart?

Hold the power button for ten seconds, go into fastboot and shutdown from there. Or just let the battery run down to zero

I had a similar problem once, leave it on charge for a good few hours and it should spring back to life.
