This is completely undiscovered territory for me, as I have been over and under the forums looking for a solution....
Here's the problem as it happened:
Every night around 10pm, I plug my phone in to charge, which I did the previous night. Normally, my schedule has me up and leaving the house at 4:30am except on weekends which I am normally up by 6am.
Friday night at 10pm, I plugged the phone in to charge as usual. The next morning I unplugged and checked the phone as usual and everything seemed fine.
I had left the phone to sit unattended for some time while I got ready to go out for the day, then grabbed my phone, put it in the holdster and left.
My day was quite busy and I never checked my phone for the first 2 hours after leaving the house. When I did it was unresponsive, so I did the customary reset and nothing.
I assumed a dead battery so I just waited until I was back in the car. When I plugged it in, I saw the red light and, assuming the battery was just dead I left it.
The phone has done nothing else since... just the red light.
I'm assuming this phone might be a goner but I wanted to put my feelers out. I have not tried MTTY yet and I'm assuming it probably won't work anyway.
Any help is greatly appreciated as I'm using a well-used and worn out Kaiser (my back-up) right now, same rom/radio/kernel/etc. to see if I can replicate what happened... (I know, flirting with disaster).
Apparently I didn't look hard enough because I found the thread for the RLoD and followed the instructions.
Charger connected, back panel off, battery out.
Hold power button and rapidly connect/disconnect battery from terminals by holding at an angle (may take up to 100 times to get it).
Red light goes out, green light flashes, phone boots.
BUT!...
Test the phone before you take it for the day.
I was unfortunate enough to not realize that the phone hadn't charged overnight and reset the battery counter to 80% at 3.6 volts.
I was lucky enough to grab a databackup.img and copy everything to the spare phone.
maybe there's a problem with the connection in the usb port.
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???
Bought a Kindle Fire HD 7 (first gen) back about 2 years ago. Has worked fine until a few months ago when my wife noticed it would randomly shut off. Battery could be 60,70,80 or even higher % charged. Once it would shutoff it would rarely boot up unless plugged into a charger for a while. Has anyone else had this issue?
I should mention it did this with untouched Kindle OS and also has done it with CM11.
Im wondering if this is just a hardware issue or if this is something that can be resolved via software/troubleshooting. There isnt anything important on the tablet so i can wipe/install as needed.
Any help would be great. Thanks

I'm thinking after two years your battery may be at the end of it's rope. You might try replacing it.
Thanks for the input. So last night i charged it to 100% and used a battery calibration app. Took it off the charger and started running stuff to keep the screen on and use the battery. Got to about 70% and it randomly shutoff. Tried booting into TWRP and was in for about a min before another shutdown. Was unable to start it up, would get to the CM load animation then it would die.
Then i did something either stupid or genius. I hit it a couple times and shook it. While doing this i tried turning it on and it booted. However after a few mins of use it wold shutdown. Did this a couple times where it would only turn on if i was shaking or "flexing" it. So this led me to believe this must be a hardware issue.
I decided to open up the back and make sure nothing seemed loose. Pulled the back off, unscrewed the battery and pulled out one end but not all the way out. Pulled some various connecting cables including wifi cable and plugged them back in. I booted with the back off sitting flat on a table and it ran without issue playing back a movie for at least 30 mins. I then put the back o and pulled up google maps and had that on/screen on for at least another 30 mins, occasionally pivoting and zooming in and out. That got me to about 45-50% battery.
I plugged it in to charge over night and will see if it now will behave. Im hoping it was just something loose. Will report back, Thanks
My best friend is having this same issue, and I was hoping if your findings have been positive. If so, we may do like you did and hopefully solve the issue.
So, here's what happened.
I have a N7000 and it's charger port stopped working a semester ago. So I bought a new one and replaced it. Everything went back to normal.
Now yesterday I was using my phone and it discharged (It discharges even while charging and browsing the internet for example), but I was talking with someone and I had to get back ASAP and conclude the conversation. So I took a older battery that's stuffed and pluged it in and finished what I was doing.
The thing is, now that I connect the newer battery (3 months old, original), I get stuck on a battery logo loop. The battery icon shows up with the circle that rotates in the middle, then the screen gets brighter, flickers a little (My phone always flicker at 25%~ battery) and goes black. Then it starts again and again in a loop.
The stuffed battery still works and is charging fine, with that said, I'm sure I don't have any problems with the charging port/cables/chargers.
I believe this has happened once before but I can't remember the procedure to fix it. Does anyone?
Thank you!

It almost sounds from what your describing like the charger block (not the cable itself) is not sending enough power down the cable, I would try either a different block or even a 2 amp charger block just to make sure.
I have a Moto X 2013 that, after replacing the battery with a supposedly new, OEM battery, refuses to charge past 3%. This phone is rooted and was rom'd with the Nougat xPerience rom, but I tried flashing it with Nougat Lineage as a troubleshooting test.
I replaced the battery last night without incident, and the phone booted and seemed to behave fine, and the battery had about 30% charge. The only issue I found immediately after replacing the battery was a battery app installed on the phone saying the battery hasn't been charged for -19000 hours, or something a long those lines (I can't remember exactly what it said, as I did not install the app, my friend did who I was fixing the phone for. I just remember it was some outrageously large negative number.). Thought it was weird, and maybe thought it was a software issue, so I booted to TWRP and wiped the cache and dalvik. Rebooted the phone, and the app reset to something along the lines of 500 hours. That is a bit more believable.
I plugged the phone into my laptop to let it charge (as it was the only way I could charge it at the time), my laptop saw the Moto, and the Moto said "Charging..." and "Android Debugging...", and thought it was working. I had to run an errand, and when I returned about an hour later, the phone hadn't moved a drop up or down. My laptop was asleep, so I assumed maybe it just stopped charging when my laptop shut off, and I was exhausted myself so I just let it sit on standby all night.
Morning came, and the Moto is dead. I plug it into the wall charger I was just using to charge my v10 with (brand new cord, made for data transferring and charging that I used once before with the old battery), and head to class, hoping it'll charge. Guess what? It didn't charge. Well, it did a little. It went up from 0% to 3%, and sat there. Annoyed, I unplugged and replugged in the phone. It came up with the white battery charging screen, switched to the Nougat "N", vibrated, then went to a black battery charging thing. Once there, the battery icon went up two squares, the screen flashed, and the phone died and stopped charging, then repeated itself a few more times until it went silent.
I started to think maybe my brand new cord was screwing up, so I grabbed another one I had and plugged it into my desktop. I had read on another thread that sometimes you can force the phone to jumpstart charging by plugging in the phone and holding down power + volume down for upwards of two minutes. I tried this, and it charged enough that I could turn the phone on again, but it wouldn't charge enough to do much more. I left it plugged into my desktop for a few hours, not allowing the desktop to fall asleep, and yet the phone was still not rising above 3 or 4% despite the fact that it says that it is charging. Oh, and the phone was on the whole time if it was plugged in, but the moment I unplugged it (Like the one time it got over 5%), it immediately shuts down.
I know I'll probably just have to buy another new battery for the dumb thing, but I am just curious to see if there is anything I can do to fix this, just because I cannot currently afford to buy another new battery (and my friend, who this phone belongs to, is getting impatient on getting it back.)
Thanks for any help!
I have the same problem, charging topping out at 3% with a "new" battery.
Did you change the battery? Did it work?
Thanks for your feedback.
(FYI, this phone is running the stock lollipop firmware.)
