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.

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

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
Ok so I got the Nook Color running exactly like I want it, rooted with custom rom and it is great however I have noticed something very odd. It DOES NOT charge when in use. I'm using the 1.9A supplied charger, and it's not doing anything except wifi on, brightness low and I just see my battery level dropping. It says it is charging, yet the number is droping.
Today I was making dinner at 30% battery. I turned off the screen, kept it plugged in and when I came back 30min later my battery was 25%. Sometimes it does charge, yesterday I did the same thing and was surprised it charged really fast.
It's confusing lol. Something I'm missing here?
Call 1-800-the nook and tell them you have a wonky charger. Do NOT mention anything about your custom rom. They should send you a new cable for free. I've had to replace mine too many times! Each one has been free.

Since this is a charging issue I will post in here. My nook charges fine, but even at 100% the light never turns green even after waiting 30-60 minutes after I notice it saying 100%.

I'd get it swapped. It's supposed to turn green, and it was B&N's decision to use a proprietary and delicate cable. I've read that any variation in the cable lighting indicates a wiring issue. I've swapped one myself.
I have the same issue but it's not the cable

I had/have the same symptoms you described but I found my issue wasn't caused by the cable (because I replaced it already) but rather it was an issue with the female receptor of the cable on the Nook Color itself. On my NC if the cable (when plugged in) is not at least perfectly evenly level with the NC it doesn't seem to connect correctly so that it either doesn't charge (or drains the battery) and sometimes the "n" on the tip doesn't ever turn green.
I discovered this as an issue with the internal recepter on the NC when I was transferring files on my PC from the NC. I noticed that when the cable's connector wasn't perfectly level or a bit higher than the angle of the NC the PC wouldn't see the device connected (it would blink in and out as I moved the connector where it was attached to the NC up and down a tiny bit).
Since my discovery (this is just on my NC - may not be the problem with your NC) I've been placing something beneath the charging cable just before it gets to the NC so that it's forcing the tip up at a slight angle. Now it charges fine every time I plug it in.

My nook color only charges when it is off, I know it is not the cable as it has been changed and, it works on my wife's nook color when it is on or off
Not sure if anyone post it already.
After using the phone for 2 months, I've just experienced the red led issue.
The phone just shutdown suddenly with 4X% remaining when doing benchmark that charging with USB. It just turned off and followed by the red LED.
At that time, I thought I was fxxxed!
I tried to plug and unplug from the PC but no luck, it just popped out the "Google" logo and then the red LED lit up and repeat and repeat.
Then I plugged in the PC again and pressed power on + vol up, it allowed to go to bootloader but soon it shutdown, which means the hardware has't died.
This time I plugged it in the AC charger, the red LED started blinking.
Luckily, charging animation appeared and the phone can be turned on just charged for few minutes.
After turning on the phone, only 1% left.

But I don't think It can drain the battery within a minute, so I decided to reboot the phone.
After reboot, I got 56% left.
Then, I got a conclusion that the red LED may be caused by the wrongly calibrated battery or overheat.
Sorry for my bad English
Or just a bad battery in general. Happened before on the htc phone I had.
Thanks for the screen shot.

Here you go this has been talked about before many times. I had the same issue happen to me and posted just like you and got some more thread links to more people that has happened too.
its just that benchmarks pull a lot of current suddenly from the battery and it cant keep up (try turning on a crt monitor while powered from a 360W ups.. the ups will turn off)..
so once the voltage in the battery drops because of the load.. the phone thinks the battery is dead.. so once you give a little time to recover and charge it for a little while.. the voltage will stabilize and it will all be a ok

There are multiple reasons for the red light. Mine got it while running antutu. Was totaly unresponsive, but could get into bootloader to fastboot the stock images back. No luck on that (still dead) so I had to RMA it
Just had this happen to me Friday night. The batterry went dead so I connected it to the charger and it turned on but then it rebooted and the red LED came on! :/

Happened to me on stock with the phone on the charger overnight. I couldn't even get into fastboot, but pulling the back off to reset the battery fixed it finally. It's such a common problem I halfway believe the LG-sourced batteries have an issue.

Theres a fix for that. Open back cover, unscrew battery connector, disconnect it, and connect it again. And dont screw it. Put the back over on and try to turn on device.

Hey this just happened to me my phone was showing fully charged and then just went black put it on charger and booted up. I'm in cm10 nightly with latest Franco kernal
Sent from my Nexus 7 using Tapatalk 2
This happened to me running the stock rooted ROM and Franco Kernel (Milestone)
The phone had died a few times, each time going to a red flashing light and would eventually power on. About a week ago, it happened again but the red light was solid and would not power on. The Red LED of Death.
I left it charging overnight for a few days and today managed to power it on. Before trying this jump-start method, I advise leaving it to charge for a very long time (several days). After around 12 hours it seems that the red light goes off. At this point I unplugged and plugged it back in, showing the red light again. I hope this helps someone else fix their phone.
Hi everyone. My Nexus 7 (WiFi 16GB) is almost unusable ever since the latest update. The tablet does not charge properly, it is very slow, and once it reaches 67% it stops and doesn't go up anymore. And it drains very quickly as well, it takes just under 4 hours from 67% to something like 10%. And even when I plug it in, I need to leave it alone if I wish it to charge, since it still does not charge (it does, but the discharge rate is bigger than rate charge, so it basically is discharging while charging). I tried flashing another ROM but I get Status 7 in TWRP, I have been getting it for a long time now every time I try to flash an update or a ROM, even though I flashed factory image on it, both manually and via some toolkit. I cannot do it now since I am not home for another week or so, and the only computer available to me is not mine.
Is there anything I can do at this point? I do not even know what is it - is it 4.2.2 or the battery itself (I tried turning it off and charging it while it is off, the same thing happens - very slow). Also, I should add that I am mainly using the original charger which came in the box, but I tried other chargers as well. It was bought from Play Store in November 2012, so I am the first owner.
Thanks

I'm in the same boat, although mine is unrooted and stock... I can't recall if this started since the last update, but it was a gradual slope down to where I haven't been able to get it to charge for the past day. at first it was just charging really slow, now it's not charging at all. I'm using the OEM charger and cord (tried another usb cord, but still nothing). When I plug it in, the charging indicator will come on, however it just doesn't charge.
I've tried all the fixes in the stickied post (plug into computer, then wall... quickly unplug and plug the usb into the charger repeatedly, turn off and charge... pop the back off and unplug and replug in the battery), but I think my (our?) issue is separate from what that thread is trying to solve.
One thing I tried is turning it off and plugging it in. the larger battery icon would show up, show that it's charging, but letting it go overnight like this, then turning it on, it's still at the same % as when I turned it off. Nothing is working.
I'm beginning to believe that my nexus 7 is on it's last discharge unless anyone has any suggestions. Below is a screen shot of my battery discharging even while plugged in. the short spike was after rebooting then unplugging and replugging it back in... but then some unknown time later it just stopped charging. the small spikes at the right are trying all the methods from the sticky thread trying to get it to start charging. I then turned it off overnight with it plugged in.. and it's the same.

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.

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.
