Nexus7 is turning itself off during overnight charge

I was wondering if anyone else was having this issue.
I've charged my Nexus7 overnight on three occasions. Plugging it in before I went to bed (~1AMish) and getting it on my way to work (~8:30AMish). Out of those three times, on two of them, when I went to get my tablet the unit was powered off. I know for a fact that when I plugged it in, it was on, and no one touched it in the meantime.
The most recent occasion was this morning.
On all three occasions, the unit still had 40-50% battery life left.
On two other occasions, I've charged it during the day for a few hours, and it was fine.
Additionally, I've never had the unit turn itself off overnight when it wasn't plugged in. And I'm using the charger/cable that came with it.
Lastly, the first occasion was on the stock kernel/rom, and the second was on the motley kernel (but stock ROM).
So it seems like something is causing the unit to power itself off if it's on the charger for too long. This is concerning, because the only thing I can think of is that it's overheating and shutting down as a protection mechanism.
Any thoughts or ideas?

Plugged mine in for the first time last night at 11:30. Slept till 8, hit the power button and everything was fine.
Basically, no issues here.

Was it fully charged when you switched it back on? I ask because I shut mine down for the overnight charge last night (plugged into a laptop, not the wall - there's only one socket near the bed and my battery-sucking phone gets that juice), and when I woke up it had only gone from ~30% battery to 55%.

I had this happen to me on the first unit I had... I was actually using stickmount to transfer some data and left the usb adapter plugged in for about an hour and when I picked it back up it was DEAD.... I could not get it to boot up at all until I did the recovery (power/volume) method and then everything was fine but I returned it anyways cause of a defective screen... I am now on my 3rd unit from Sam's Club and I think I might have a keeper...? (Knock on wood) :fingers-crossed:

Yes, it was at 100%.
Keep in mind that charging via computer's USB port takes much longer. Maybe your laptop went into sleep mode and shut down power to the USB port?

Nope, my fiance's phone was plugged into the same laptop and it was fully charged in the morning. And as a general rule, I've never known the computer to automatically sleep while on AC power, even when the screen is closed.

Thank god i'm not the only one experiencing this. My nexus 7 always seems to turn off after I leave it overnight plugged in for charging. I thought it was a kernel issue but i've switched kernels and i still experience it. Still unsure as to what is causing it.

Same here. Its odd it only seems to be for an extended period of time. Also my battery was indeed fully charged. Should I exchange at Sam's?

There is nothing else wrong with the tablet. I have a feeling it could be some sort of hardcoded feature where if it notices that you're plugged into the wall charger with 100% battery and the tablet is in deep sleep for a certain period of time, it automatically shuts down.

Ikr. First time it happened to me I was like wtf? It might to stop the 2 amp charger from overcharging? My unit is fine, I think the sound is just right. I might get that squaretrade warranty though.

Well, I feel a little better that I'm not the only one with this "problem".
The question is, is this a "problem" or a "feature". I guess we won't know unless we ask Google/Asus (good luck getting that answer) or enough people respond saying that it happens to them too. But if people start saying it does not happen to them, it makes it more likely to be a problem....

This happens to my phone due to overheating. The tablet does run hot when charging. See if there's a temperature logging app and run it overnight.

It would be nice if it would just cut off the battery charge and run directly on A/C. But I guess I would rather have it power off than explode.

isnt bad to charge it overnight like i believe from 1% to 100% chrge is like almost 3hrs fully chrged.. i just alarm myself for 3hrs to check if its fully chrged already then unplug it

True, it's not good to constantly charge the battery once it's full.
Most devices however have a built in charger kill switch once it reaches that point. Laptops for example will switch to A/C power and only start recharging the battery once the level drops to ~95%. I believe my phone does this as well (SGS2).
I guess I'm OK with it turning itself off, assuming that it really is a safety feature. My main concern was something was wrong. It would have been nice if they mentioned this in the 100pg Nexus Guide eBook though .

I want to add my own observation -- mine was almost fully charged, I plugged it to my computer's USB, turned the screen off, walked away. A couple hours later, the Nexus 7 was turned off. But I was shocked to find that, pressing the power button couldn't turn it on. The first thought came into my mind was that my computer did not charge the Nexus 7 and the battery ended up completely drained. So, I plugged it to the wall charger, left it on for a day. 1 day later, I tried to turn it on again. No, it didn't work. I was panic and decided to Google about how to reset and checked if I could wipe it and sent it back for a replacement. I found that pressing the power, vol up/down button at the same time can force a reboot. I tried that and bingo, it booted into the bootloader. Before I wiped, I decided to try to boot back to the Android OS. Surprisingly, that worked. I was happy and decided to ignore this incident. Then, today, it happened again. This time, I immediately used the power + vol up/down trick to reboot, and that booted me right back into Jelly Bean. I checked the battery status and it's fully charged, which meant my computer was charging it all along. For some reasons, the Nexus 7 would just turn off itself. And, in my case, pressing the power button alone would not reboot it.

Sounds like to me that it's hard locking, not "powering off", and you're forcing a reboot. Long-press of the Power button should do the same thing.

I can't say I have much to offer in regards to this issue, but am I correct with my observation that everybody experiencing this issue has experienced it while their N7 was plugged into a computer of some sort for an extended period of time? Has anybody had this happen when plugged straight into the wall outlet?

Here's another update with an interesting 'twist' since my last post.
I've charged it twice in the meantime. Once was, again, overnight, and I woke up to find it powered off. A simple "on" press brought it back on.
However, on Saturday, I used it heavily and was down to about 40%, so I plugged it in around 11AM. I meant to grab it around 3PM when I went out, but forgot about it. Got home late, and went to look at it at about 11PM (12 hours later). It was charged to 100%, running off the A/C power, and still on.
This is weird, because if I leave it plugged in "overnight" for 8 hours, it will almost always turn off sometime before I grab it. But when left plugged in during the day for 12 hours, it stayed on. I wonder if it handled the situation different based on the time of the day???

[Q] Is my Nexus 7 dead? Please give me options to charge/turn on

Good evening everyone, I have a Nexus 7 8gb, but the thing is, I cannot turn it on now.
It happened as follows:
I was using it every now and then, mostly to read and play.
I was using the charger to charge my cellphone too (XTC Explorer) as it was a lot faster, being 2amp/h.
I updated the cell to 4.1 and at the same week noted the battery wasn't running that long, but blamed it to the rom.
The cellphone also took a lot longer to charge with the nexus charger, yet again I blamed the rom.
I noticed the Nex was at 8% while reading so decided to charge it, but I guess I forgotten.
The next time I wanted to use it it wouldn't turn on. I figure it had no battery.
I plugged the nexus charger to the nexus a whole night and in the morning it still wouldn't turn on.
I figured something must be wrong with the charger, so I tried with the cellphone and nook color charger, but both are .5 amps/hour.
It wouldn't charge, neither connected to the pc (also .5a/h via usb) so I tried a psp go charger, as it is rated at 1.5 amp/hour, much closer.
I connected it at night and saw the charging icon (white on black battery with the ray) and left it overnight.
The next morning it wouldn't turn on either.
I've bought it almost two months ago and I really enjoy it =) but now I'm desperate.
I cannot call google play for the warrant because I'm in Argentina, and I don't believe they will ship me a replacement, nor anything. This one my brother bought from them, but he went back to US a few days ago, and I didn't think of giving it to him to RMA.
I tried keeping the on button, for 5 secs, 30 sec, 90 secs, 120 secs, and no dice. Also tried holding the Up Volume key to restart it, but no chance.
Please help!

Had a similar issue to this over the weekend after not charging for 2 days and the battery going dead. I let it sit on the original charger overnight and for some reason it did not charge. It kept booting and shutting down once it booted due to a low battery warning. It eventually got to the point where the screen would go to fuzzy lines and light but no boot.
To finally get it working I did a combination of a few things but don't actually know what got it going.
Put it on a different (kindle) charger and let it sit for an hour or 2, did several hard resets holding both just the power and also the up/down volume and power all at the same time for up to 60 plus seconds. I switched back to the stock charger and did an additional hard boot by holding just the power for 30+ seconds and it started booting and charging.
I did however put it on the charge again last night and noticed this morning it was still at half battery and didn't get a charge. I ended up putting it on a mifi charger this morning and it's charging again so don't know what is up with the stock charger. Also, have all the latest updates to 4.2 as far as I know as there have been charging issues reported with earlier versions...

Try this, it just saved my device:

try holding down the volume DOWN and the power key for 10 seconds, then release the power key and keep the volume down key pressed, and it will force the unit to restart into the bootloader from any stage, its effectively like pushing the restart button on the front of a computer and constantly pressing the delete key to get into the bios.

[Q] OTA update to Lollipop: Terrible battery life, very slow charging

I just got the OTA update from KitKat to Lollipop (5.0.2) yesterday and I've noticed terrible battery life and very slow charging since then. My phone is always in its charger overnight and when I remove it from the charger in the morning it usually easily lasts until I put it in the charger at night again. During the daytime I do a lot of stuff on it (whatching youtube videos, listen to internet radio, whatsapp, internet browsing, making phonecalls etc).
This morning I removed it from the charger and hardly didn't do anything on it for the first two hours. When I wanted to send a whatsapp, I noticed battery had already fallen to 70% in only 4 hours or so - 4 hours of doing nothing while the phone was in energy savings mode! Half way through the day, with only some whatsapping, battery had fallen to 20%. When I connected it to the charger, it instantly dropped to 8%. After about an hour of charging, it was at 17% and said it would last another 6 hours before the phone would be fully charged. Usually I charge my phone in 1.5 - 2 hours!
When I did the update, I didn't do a factory reset and I would like to only do that as a last resort.
If I look at te battery statistics, I don't see any app using an obscene amount of battery life - the highest being Google Play services with 15%. But what I do notice is that "Cell standby" is responsible for 29% of the battery drainage.
Before I do a factory reset, anyone any tips?

This is directly from HTC tech support. To recalibrate battery and HTC charger when battery rapidly or erratically discharges, this procedure clears all battery stats, coordinates and normalizes charging.
Turn off Fast Boot in settings. Power off phone.
Plug phone into HTC wall charger and charge for two minutes or more
While charging, hold down volume up+volume down+power button and continue holding
Phone will turn on and off repeatedly every 15 seconds or so while continuing to hold all three buttons
Keep this going for 2 minutes, then release buttons WHEN THE PHONE IS ON
Now, let phone charge fully normally (with phone either on or off--doesn't matter) and battery level reporting, charging and battery life should be normalized.
Do this every month or so to keep power system healthy--even if everything seems fine. Also, don't leave phone on charger overnight for best long term battery life (according to HTC tech support: "The first thing they tell us." This is true even though charging is supposed to turn off when battery is at 100%)

Battery recalibration ... Many techs say it's a placebo. But, I will follow this manual, just in case.
I do confirm, though, that with L 5.0.2 charging takes longer, phone drains faster with the same as before apps and usage, phone is often hot, and I've started to get regular 'can't charge, your phone uses more power than available from charger'.
Re phone uses more power than available, it happens with all three original HTC chargers I have, so I have to use the charger from an Asus tablet (1.5A output).

I haven't done the recalibration thing but I did some measurements and I now know why it's charging so slowly, just not what is causing it. The phone isn't switching to high charging mode and keeps charging at around 400mA. This means that when using the phone, it's draining faster than it can charge. I also think it's not switching to standby mode causing the high drain. Often the phone gets hot when it's in my pocket (when it is supposed to be in standby mode) meaning something is still draining the battery fast.
I will do the calibration thing and see if that helps.

I just did the reset thing (holding power + vol up + vol down) for two minutes. It's now charging but I can see it's still not charging in high mode. It's still charging at only 400mA.
Edit: Phone says it wil take 10 hours to charge (it's at 30% now).

Annoying, I know, but I'd factory reset the phone just to make sure the update has 'taken' correctly

Sounds logical. How did you find it out? Instrumental, or through a phone menu?
I have checked Setings/Power. Mine says Charging on AC, which supposedly means high charging mode.
PS. Again, whatever it might mean, when I get a 'phone uses more power than..' error, I connect the phone to a 1.5A charger (compared to original HTC 1.0A) and it solves the problem. I'm not happy with this solution, though.

There are a few ways I can measure this. I have a "Charger Doctor", one of those inline USB voltage/current meters and I have an "Energy Meter" which measures wattage going out of a 110/220V socket. Both confirm each others measurements. The Charger Doctor says my phone is being charged at 5.1V at 0.4A, and the energy meter says the charger consumes about 2.5W which is about right (the charger looses some energy through heat and the Charger Doctor consumes a bit of energy as well).
But...
To be sure, I tested a few different (but identical) chargers and changing the charger made no difference. But - and here comes the strange part - I tested about 20 different USB cables and with only two my phone charged at 1.0A (which I assume is the M7's max charging current). With all the others it charged with 0.3A-0.5A. Only with those two cables it charges in high charging mode. So apparently something changed in the charger detection. Before the update I was able to charge the phone in high charging mode with other cables as well.
Also, it seems like it's now discharging not as fast as before, but I will be sure tomorrow after it has fully charged and after I've used it all day.
Edit: Yep, charging is at it's normal speed now. It's at 60% and the phone says it will be 1 hour and 1 minute until it's fully charged.
Edit2: Of the two cables it charges at 1.0A with, one is the original charger cable that came with the HTC, and the other is a cable that came with a Duracell Power Bank.

Well, after the three finger calibration, charging seems faster, and I think battery holds longer (or maybe I want to think it does, because still not sure).
One additional observation is in about 20% cases my phone is stuck during boot until I connect or disconnect the charger for a second. By connecting or disconnecting the charger, something triggers the power state and the phone boots normally.
So yes, you may be right about new power management in Android 5.
(I'm now on IC7.0.0 + ElementalX 20.0, HTC M7 Int'l))

Well, even though charging times seem normal now, it is slightly erratic. I can see the percentage making jumps up and sometimes down while charging.
Also, battery life still is very poor. Battery now lasts until halfway through the day while before it would easily last all day...
Is there a way to revert to KitKat? Other than a lot of annoyances I haven't noticed a single advantage using Lollipop.

Factory reset
I had terrible battery problems after T-Mobile upgraded my HTC One (M7) to Lollipop. The phone was constantly awake and churning with the GPS probing for a signal every few seconds. I'd lose 50% of my battery in a couple of hours. I went through the battery recalibration suggested by HTC support, but it didn't work well. Finally I did the factory reset. It worked perfectly! Now my battery life is better than ever and the phone will go well over 24 hours on a single charge with normal usage. Recovering from the factory reset was easier than I anticipated. Google Play Store remembered and reloaded all my apps automatically. The only headache was having to log in to everything again. Well worth the effort.

I did a factory reset as well and it looks like it has improved battery life. I'm still on my first day after the reset so I won't be able to really tell after I've used it for a couple of days. But like I said, the hard reset seems to have made a difference.
It has been 15 hours now since I unplugged the phone from the charger and it still has 43% left. But I just noticed a few minutes ago that two energy settings were set different than before the hard reset. Screen brightness was set to auto (when before I had set it to it's first dim setting), and data connection was set to switch off after a long period of inactivity. (while before it was set to always on). I've changed those settings and see if that makes a (big) difference.

Tested it for another day and battery life has definitely improved quite a bit but it's still nowhere near what it used to be with KitKat.

when i woke up this morning my m7 was 100% it's now 11;10 and it,s now 70%

I'm getting exactly the same problem.
HTC support said they never heard about such a problem and their conclusion is to send the phone to be repaired
I don't know how to rollback to previous version and it doesn't looks like to be a new fixed version on the way.
Or at list I haven't heard about it.

I also noticed it doesn't make much of a difference if I turn on energy savings mode.
With KitKat, my phone would easily last the whole day without energy savings mode. Now with lollipop I have to hook it up to a charger in the evening - even with energy savings mode enabled.
The thing that sucks the most is that my phone drains in alarming rate when playing a game, or listening to online radio or watching youtube videos. 30 minutes and battery drops from 100% to 50%. And the phone gets really, really hot. Before lollipop, it would drain perhaps from 100% to 85% and the phone would not heat up at all.
There are so many annoying bugs/features with lollipop, I'm considering an iPhone for the very first time ever as my next phone. Mind you, I've never been a fan of Apple stuff. But Android is just getting ridiculously bloated and simply doesn't work very well anymore. It looks like every update makes my phone less usable. And I hate the fact Google thinks it's perfectly fine to disable/remove stuff that people have come to depend on. Like my notes (amongst man other things). Google in all its wisdom has removed the Notes app making all my notes inaccessible. The only way to get my notes back is to install some third party app from the Play Store and have it transfer my notes to the cloud. First of all, I don't want a third party app handling my notes. And I most certainly don't want my notes stored in the cloud. I travel quite a bit and I don't have internet access everywhere I go, making my notes inaccessible again.

Battery %100.-0% in over night

I charged my battery. Took it off the charger and turned off the screen. When I woke up the phone was off and I dead. I am on cm12.1 fairly recent update. I updated a couple days ago. I just want to know if anyone else had this issue?

Only time thats ever happened to me is when I was camping in the woods. Like it was searching for a signal all night and killed the battery.

I had something similar happen to me over the weekend. I mostly use a Choetech Qi charger, and pulled it off the charger Saturday morning before heading out for a day of motorcycle riding. After the ride...~6hrs later my phone still showed 100% battery. As I was catching up on emails etc..the phone just shut itself down. I rebooted...then it shut down again within 30 secs of use.
While it was still off, a quick press on the power button popped up a battery image showing 0% battery. Within 2 seconds of plugging in a charger...it jumped to 100% again. But the phone would not stay on, unplugged at all. I tried wiping the cache hoping that would clear out the battery monitor, but not luck there. The only that worked was turning the phone off, plugging in the OEM Turbo Charger, and letting it charge over night.

Do you have any app monitoring battery usage like betterbatterystats or gsm battery monitor?
sometime obviously kept your usage on while you slept. not normal. either searching for a signal all night, or a misbehaving app, etc. y

I do not have currently have any 3rd party monitoring app. But it's probably not a bad idea. I just think that something with the wireless charging eventually whacks out the battery calibration. As long as I can "reset" everything with a night on the Turbo charger, I can deal.

Radon,
I'm seeing nearly the same problem, but mine is at 80% not 100%. I tried doing a full charge on a standard (non-Turbo) charger overnight, and it changed things, but still not in an acceptable state. Did you try using a standard charger? Or did you only try the Turbo charger?
Verizon and Motorola are telling me I need to do a factory reset and/or get a new phone, but I'm trying to do my research first.

Clear the app cache (Go to Settings->Storage then click on Cached data and hit OK). Then reboot into recovery to wipe the cache there (note it'll take upwards to half and hour so don't freak out if it looks frozen). Then turn the phone off and leave it on the factory charger overnight (or for a while after it reads 100%) with the phone still off. This clears the cruft to fix misbehaving apps, then calibrates the phones understanding of what a full charge is. You also might want to delete any apps you no longer use, especially ad-ridden games, system hook apps like keyboards, and things that track location or status which might keep the phone awake.

After I shattered my screen on my last turbo and got a replacement I've been having issues with my battery. It would randomly die and wouldn't respond or let me turn it on without connecting to a charging cable. Sometimes it goes from a good charge to 39% and turns itself off but often, like I observed today, when I looked at my battery trend it actually went from 75% to 8% in an instant. Not sure what the cause is. Could the battery be discharging somehow??

Weird Battery issues

So my turbo just turned 2. For the past 6 months or so been having some weird issue. I was on RR Remix for a while, then went to CM14 by BBH27 for a while, and then back to RR, and now on ComputerFreak Stock. I don't have any issue with charging the phone. Quick charge works just fine.
I have had issues where the battery will just be dead even if it was at like 50% and confirmed charging.
I thought maybe it was my stupid charger (I have another that I have yet to test) but then last night, after charging my phone before I went to bed i unplugged it. I woke up around 6:45 to find my phone once again dead. It looks like around 2 am the battery just fell. Dead. Just gone. I go and hit the power button and i got 1%. The battery graph looks as if i turned the phone off. For the most part my battery last all day 12+ hours with some good usage too.
I'm getting ready to flash back to stock now that full stock MM is out now to flash and see if that makes any difference.

For what it's worth, my Turbo would just straight up shutdown when I was on RR. And not go through the shutdown process, just crash to a powered off state. It would happen if the battery was full, low, or anywhere in between. I don't know if that's the issue you were experiencing, but I suppose it's possible.

My daughters is having the same issue.
Anyone have a solution?
I've tried clearing caches, battery recalibration, etc.
Going to see about doing a fully clean install tomorrow if she is okay with it.

When this happens and the phone just shuts down, does the battery percentage immediately jump back up when you plug in a charging cable? I was having that problem when using wireless charging a lot. It turned out be a battery calibration issue. You can re-calibrate by holding the power button and KEEP holding it when the "Power Off" dialog pops up. The phone will eventually reboot itself then leave it overnight on the factory turbo-charger.
One warning - Since the marshmallow update, performing this procedure seems to wipeout your BT connections.
