A very wierd Nexus 7 experience

I was one of the early pre-orders and received my Nexus 7 last Tuesday evening (7/17).
Like most users, I checked it out for problems: screen, mic, etc.
Everything checked out fine.
I did some customization, downloaded some apps, tried out all the new features.
Everything worked well.
I had connected it to my PC, no problems. Rebooted it, no problems.
After about 6 hours, I put my Nexus 7 to sleep (not shutdown) and
started to prepare to go to sleep myself.
After about 5 minutes or so, I decided to download one more app.
I tried to wake up my device -- and it would not wake up!
I tried a long press on the power button -- still no good.
Thinking maybe the screen had gone bad, I tried to connect
it to my PC to see if it could be recognized -- no good!
Yikes, could my Nexus 7 have died? I decided to try
to charge it, plugging the charger into the wall. No little
charging icon showed up on the screen
I decided to just let it charge overnight and see what happens.
The next morning, the Device still would not power up
I called google play and told them my story and they
said they would start the process of sending me a new
Nexus 7.
I started looking on the Forums, to see if anyone had
the same experience. Some people suggested that
I hold the power button down for 30+ seconds.
I tried, 30, 60, 90 seconds ... still no good.
Over the following days, while waiting for my RMA process to play out,
I would periodically pick up my Nexus and try the power button -- no good.
Today, 9 days later, on a whim I decided to again plug my device
into the charger. Believe it or not, the charger icon went on!!!!
After charging it for about 90 minutes, I booted it up and everything
was working again!
The replacement Nexus has not shipped yet, so I have a few days
to see if this problem occurs again.
My guess is that my device got into some hardware freeze situation.
The battery finally ran out of juice which caused the machine to
completely shut down -- which allowed me to re-charge it today.
Any other thoughts?

>Any other thoughts?
Maybe you can give the hidden reset button a try the next time?
NB: For the unfamiliar, a video teardown showed a reset button at top of the unit, but no hole through the casing to access it.

I did do that at one point. However, if I did it at a point
where the battery actually had run down I still would
have needed to re-charge the device -- which I did not
even try until today. Nice to know though.

I haven't had any issues with my nexus whatsoever thus far. I really hope these are anomolies.

Sounds like the ever so familiar sleep of death that occurs on custom Roms. It requires the reset button or let the battery die

I'm kinda glad I didn't get my Nexus 7 yet. LoL!! All these issues ppL are having.

Phone powering off at 70% battery

Hi all,
My Nexus 6 GPE has been powering off after about 2 hours or so being disconnected from the charger every morning. The phone has 70% of power (going off of this last time it has happened, usually it is around 50/60%) and it goes into battery saver mode and says it is powering down. When I try and restart. sometimes it goes and instantly shuts down, other times it shows the battery is completely dead (ie the empty phone icon), with this last time I was able to get into recovery and stay on and the bootloader and in recovery it says I have 60% battery left.
This all started when I flashed the latest software (LMY47E) and the latest bootloader/radios. I used Nexus Toolkit to Factory Restore it and it is still doing the same thing, sometimes it doesn't even give warning before shutting off. Has anyone come across this before? Do you think it is software or hardware related?
Thanks for your help

Did you try this?
http://forum.xda-developers.com/nexus-6/help/dying-17-battery-t3062050

I did try that, it seemed to work but then turned off again. I did it about 3 more times, so far it hasn't shut off again, it was around 52% when I did it last and it came back up as 27% so I am hopeful that worked.
Has anyone else experienced issues because Qi charging? I have almost exclusively always charged this with a Qi Wireless Charger.

I have been having the same issue. Just did the "fix" from the other thread and before reboot it read 98%, after boot it says 77%. Crossing fingers.

UPDATE:
Nope, didn't work. After it went to 50%, it shut down and won't start on it's own unless it is plugged in. I'm back to step one.

That sucks. It seemed to work for me. Phone drained to 5% and automatically shut down. Charged it to full without booting, so if it still behaves, it fixed me.

Dacian like i just wrote in the other thread:
The "fix" i posted plus no more charging with Qi chargers worked for me.

I tried that, didn't use Qi charging to get it back to 100% and it still shut off. Can you use Qi charging again? I didn't spend $700 on my Nexus 6 so I couldn't use all of the features. I own 4 Qi chargers so that I didn't have to plug in my phone at all unless I was doing something through ADB.

No more Qi charging since I tried the mentioned workaround and no more problems with my N6 shutting down too early.
But I agree: not a solution if you use Qi stations a lot.

I think I'll just warranty it and if there comes a time where this starts happening again, hopefully there'll be a fix from google for it or something. Thank you for your help.

You're welcome. Good luck and keep us posted!

my phone was doing the same exact thing...first started off shutdown at 20 then 40 now 70! phoned motorola for a replacement : "sorry we cannot send replacements but we can fix it"...WTF?!?! a phone like this?! why the F would i want a repared faulty phone?!? Motorola never again never...

I have the same problem (now shutting down at 65%), i already call google for replacement but untill now i never had confirmation

I have the same problem. Nexus 6 shuts down. Displays blank white battery. Cannot be turned on without plugging into power source. Upon powering up it shows plenty of power.
Possible helpful info:
1. Recently manually updated to 5.1
2. Recently started using Qi charging
I did not notice a problem until both of those -- of the two my suspicion is the wireless charging but it's a total guess
I've tried all the suggested fixes and none worked.

Phone dies when it hits 5% battery

So, multiple times now my Note 5 has died within a minute or so of hitting 5% battery. The battery percentage will quickly plummet to 0 and shut down. However, when I plug it in and it shows the charging while the phone is off screen, it shows approx 5% battery. I assume this is a software bug and there isn't anything I can do about it until the next update. Either way, I wanted to see if anyone else is having this issue.

Don't let it get so low anyway. It shortens the battery life.

Yes, thank you. The phone had only ever hit this low a small handful of times.
Regardless, the phone's behavior is not normal. It reminds me of the Galaxy S2 that I had for all of a month in which I was certain was a defective unit. The entire battery would not last more than two hours of use as it would plummet like a rock -- especially in the last 50%. Similar behavior in the note, except --thankfully-- it's only at the last five percent and the battery appears to still have that five percent inside it. The phone just seems to think that it doesn't and shuts down.

Turn off your phone, and then turn it on pressing and holding Volume Up, Home, and Power button at the same time until you see a warning. Then press Volume Up to continue, and navigate using volume keys and select wipe cache/factory reset with the Home button, then reboot.
Please note that by doing this all your data will be lost.

I likely won't restore my phone unless I get super annoyed by this. I'm going to wait until the Marshmallow update to see if this improves with it.
I just watched the phone go from 8 to 1 percent. It wasn't doing anything and I was just staring at it. This was the first time I had ever plugged it in right before it turned off. When I plugged it in, it shot right to 7 percent. I then unplugged it and watched it go back down over a few minutes. This is very odd.

Why do you damage your battery this way? Keep it topped off always as much as possible. Letting it run low shortens it's life. This is a known fact with Lithium Ion batteries.

Sounds like a bug. Easy fix with update
Sent from my LG-H815 using Tapatalk

Did you try just wiping the cache without wiping the whole device? My suggestion is charge it to 100%, unplug charger, wipe cache (While phone is off, press and hold Vol Up + Home + Power buttons, release Power button when you see the initial Samsung Galaxy logo), power down, plug charger back in to make sure it stays 100%, then switch phone on.

People (edit: same person both times ) need to calm down over the fact that I occasionally use my battery to 5%. I mean, really.
Yeah, I imagine it would fix with an update.
Shadow, I'll try that. Thanks.

Download Battery Calibration from Play Store.

Same **** here. So annoying!

I knew there HAD to be others experiencing this. Do you have an AT&T model?
I'm currently attempting the battery calibration app route. Most seem to be root only, but I found one that didn't need that. The instructions were to charge to 100%, then use the app to calibrate, discharge fully, then charge to 100%. I'm currently on the last charge -- it discharged over night.
Hopefully this works.

It seems that the battery calibration app has done the trick.

I have this issue as well

XT1097 turning off when the battery is less than 30%

My Moto X 2014 works perfectly, all of its features.
Only one thing is bothering me when the battery is less than 30% cell turns off and when religo it shows that it has more than 20% battery but when it finishes the boot turns off again.
Someone has gone or is going through this problem?
My phone is with the original ROM, unlocked bootloader and custom kernel to be able to root.

I had a similar problem on my XT1096 but the threshold was more like 20%. It would hit between 20%-15% and just turn off. I actually got Motorola to replace it under warranty cause I thought it was a battery problem. My replacement has done it once already. I never figured out what the problem was. A factory reset made it go away for about a month. Then it started happening again pretty regularly. That's when Motorola replaced it.

Thanks for your reply, awaiting more comments/solutions.

Yeah, mine did this @ 12-9% threshold... which really wasn't too bad, but not reliable for general day to day use. You can try calibrating the battery [Google: Calibrate your battery], and seeing if that helps. It didn't for me. Long story short; i went to ebay and bought a broken Moto X 2014 for $30 and i swapped it's battery in my original. I bought many "authentic" batteries on ebay and guess what, they were fakes and never worked. If you chose to go this route, the MOTO X is pretty difficult to open properly without ruining the back. I bought an additional wooden back from China via Ebay. I no longer have this problem, the phone gets to 1-2% before it dies now; which is much more reliable for my use.

Charge phone to 100% leave plug in turn on phone wait till boot animation shows then hold Power button until it restarts, do this three 2 times.
Repeat later on if you have to.
It should work.

Wow, haven't tried that! I'll check it out tonight. Thanks
My solution is calibrating it with this and I get it to work again. So, is there something physically wrong with my battery and this is just some kind of patch?

I tried this and it actually made it worse. My phone would consistently shut off at around 30% (oh, and I can get MAYBE 5-6 hours out of it before it shuts off, so I can never go anywhere without charging cords, VERY annoying!!), so I tried this. For one, the phone shuts but doesn't restart when I am holding the power button during the BU animation, it just shuts off and no matter how long I hold the power button, it doesn't restart. One of the times I did it, I DID get a green LED shining inside the slot at the top which serves as the earpiece for the phone. That time I had to hold the button a LONG time for it to restart. The end result of all of this is now my phone shuts off at around 40%!

Try downloading ampere app and seeing the health of your battery

This is definitely battery problem my friend...nothing can be done except replace battery ...my entire state doesn't have a good customer care to replace this sh#t battery and now am going to change this stupid phone ..am done charging all the day and sudden turn off s too..

Stock Nexus 6 won't turn back on.

Maybe I have horrible luck with Nexus devices but my Nexus 6 turned itself off and will not turn back on.
I was listening to youtube music on my bluetooth speaker and it shuts off(had about 75% charge) and became none responsive. after couple of music Holding series of buttons plugging in original/multiple Samsung cables has no effects on it what so ever. I had opened it and checked if battery is ok but battery isn't the issue. Any suggestion before I sell this as is on eBay?

And when you Holding the Power button for 10 sec?

What's it say when you plug it into a pc

Something similar happened to me when i was listening to music on YouTube. The touch screen stopped working, I could turn the phone off and back on again but the touch sensors weren't working at all. So i unplugged the battery and kept it out for couple minutes and plugged it back in and everything started working once again. But when i restarted the phone, it wouldn't turn back on. I kept using different wires and chargers and the screen lit up after around 20 minutes. I held all the buttons while messing around with chargers. You could try letting it charge for a bit and put it in recovery if its possible.

OK worth a try. I am going to open it up and let it sit for a day.

If nothing works, your motherboard might have shorted out maybe from condensation or maybe a faulty connection. If the screen doesn't turn at all no matter what you do and there are no vibrations when getting into the bootloader then you are out of luck as its most likely the motherboard. But if there are vibrations or any sound then its the screen. I'm not gonna say it with certainty but you could possibly get a new battery and see if it's the battery(I know you said its not the battery but unless you can actually see inside the battery you cannot say its not the battery). The way i see it is you can buy a replacement battery for $20 tops and if it ends up working then you saved the phone but if it doesn't then you lose $20 max and you can sell it.

It looks like you've read my mind.
I had replaced one with supposedly OEM end of last year., but it won't hurt to spend like $20 and see if it isn't battery issue.
Thanks,
