Recently I purchased my first tablet, ofcourse the Nexus 7 32 GB and I am very happy with it.
As soon as I started it, I received the notice that an update was ready to be installed, which I did (4.2).
After that I got another notice to install 4.2.1.
So far so good, everything worked very well....also the normal charging with stock charger and cable.
Then after about 1.5 weeks I noticed that my battery level didn't went down from 100% to xx%, even after playing games for several hours.
I am absolutely sure this wasn't the case before, I did charge well and battery-level went down normally.
So because I couldn't tell if the battery was empty or not (because it kept being on 100%), the Nexus went down ofcourse.
Well, I plugged in the stock charger and cable and started to charge it.
Battery icon (when Nexus is off) nicely went from first quarter (25%) to full (100%) when I unplugged it.
It booted up nicely, but then I noticed that the battery-level showed 0% and kept stating 0%. Even again after playing games for several hours (GTA4 and RR2).
Normally it should decrease in battery-level ofcourse.
So now I'm stuck at battery-level 0%, but strange thing is that the Nexus works fine besides this small problem.
I can charge it, play with it for several hours, reboot, deplete the battery, etc....
Only thing is I can't see the actual battery-level which is very annoying, since I never know when the battery is empty and needs to be recharged.
I searched internet using Google and also here on XDA, but never found a solution.
What I already did was :
1. Reflash stock ROM, using the Nexus Root Toolkit.
2. Flash CM 10.1 with CWM Touch
3. Tried to hold down POWER + VOL UP + VOL DOWN for 30 seconds
4. Tried POWER + VOL UP
Nothing I did worked.
Did someone had this problem before and was able to solve it ?

Hi,
I had this issue too when i purchased my nexus 7.
For solve the probleme I've remove the back of the tablette then unplug and replug the battery.
Don't had any other issue. its realy a nice tablette you have make a good choice.
Sounds like a problem with the fuel gauge chip... Not sure if you can fix it.

Try fully charging with power off then deleting your battery stats file...

That file only stores the data used to fill the battery graph... It has nothing to do with the actual calculation of battery percentage.

Oh well, was just an idea.. Thanks for enlightening though..

Check out this thread, there's people talking of a fix for PA for battery percentage stuck at 100%.. Maybe the same cause as your problem... Look from post #10047 onwards.. Makes me think its probably not a hardware issue at least.

In PA, is definitely a software issue and seems to be caused by paprefs. The issue that is commonly reported with the N7 across all roms is typically caused by the battery connector not being properly seated. Asus QC consistently has fallen short on this connector.
Sent from my Nexus 7 using Tapatalk HD
I have fixed multiple loose battery connectors using clear scotch tape. The problem is that they didnt use any adhesive on the battery for a batch of n7`s. Makes it possible for the battery to slide back and forth at least 5mm. When it does it pulls the internal battery lead right off the mother board connector. Tape the connector tight. Then tape the battery to that side. Do NOT tape over the copper tape. I even made a small strip of foam to place along the far side of the battery to remove the room to slide.
Easy fix for an annoying problem.

I can surely try to open the back and check if the battery cable is seated correctly, but I'm wondering....
If it isn't seated correctly, wouldn't that mean that the battery isn't charged at all ?
In my case the battery is being charged and depleted normally, since I can use the N7 to play games etc.
Only the battery-level indicator keeps telling me the level is at 0% and it says "unknown".
It's just annoying as I don't know when it's fully charged or fully drained.
Now I let it charge for a complete night and work with the tablet untill it dies on me.
Just to let everyone know, who might face the same problem :
I pulled off the back cover and found out that indeed the connector, coming from the battery going to the mainboard, was not fixed in its socket.
It was not completely out of the socket, just not firmly pressed.
So I pressed it firmly and put back the cover.
After restart, the readings are back to normal.
Thanks everyone for pointing me in the right direction.

I have exactly the same problem!! Can you please help me. I tried what you said - removed back cover, pressed the connector hard, and switched on again. The problem is still there. Can you look at this picture - http://android.hdblog.it/wp-content/uploads/2012/07/Nexus-7-Teardown.jpg and tell me if the connector are the red and yellow wires on the left, on the side of the tablet closest to the camera? If so, how did you press it? Could you explain those steps once again please?? Much appreciated!

Make sure you put a piece of tape on the connector to secure both pieces together and also one on the battery to prevent it from shifting. The newer n7's had a battery that didn't fill the space for it...allowing it to shift and pull the connector free.

I had exactly the same issue. Word 4 word.
I took the back off my n7 (take the SIM holder off 1st, makes getting the back off much easier) and noticed the battery connection was loose. Unplugged fully, replugged and got my battery % back! :thumbup:

First off, for everyone that has battery-related problems, please check my thread:
http://forum.xda-developers.com/showthread.php?t=2090826
It provides "fixes" to a number of battery-related issues.
Second, the cover is really easy to get off. Just use your fingernails. Start half-way down one of the long sides (I forget which, but try both - your fingernails will easily slide into the seam). Gently snap off the cover from your starting point. Slowly work your way around. If you go slowly/carefully, it'll come off rather easily and without breaking off any tabs. It snaps back on easily as well.
In my post, I recommend that you apply a small piece of electrical tape on the battery connector, as they have shown over time to come loose for a number of N7 owners.
In all but the occasional rare case, N7's with battery-related issues are easily "fixed" and do not need to be returned for replacement. Just read my thread. It'll save you a lot of time and frustration. It'll also might save you from a needless return!
Good luck and report back.

Strange. my tablet is doing the weird battery bug. Battery stuck @ 100% for quite some time, even after a whole day of idle and @ home usage after work.
Realized it wasn't dropping.
This morning, I opened up the back and checked out the battery. It was glued down so not shifting around, but I noticed there were fingerprints on the copper material. Odd thing is I bought this tablet new. Box was sealed and everything.
So far I unplugged the battery and plugged back in. Haven't turned the device back on just yet. Might wait a couple hours and see.

Yup I stumbled upon your thread after a bit of searching. The tablet was actually rather new, just purchased a week ago. Was charging and draining fine for few days of ownership, and all of a sudden it started acting up. I realized it was too good to be true seeing 100% battery % after a whole day + gaming on it @ home.
This may or may now help anyone.
I was using my phone and it just **** off on me. I wasn't flashing a rom or "tinkering" with it. I am rooted but was stock. No kernel. Connecting wall charger or connected to PC would just result in blinking red light.
I removed back cover (be careful doing this) and disconnected battery from mother board. Connected it back up and BAM...all is well. No loss of data...turned back on on the state I had left it.
Maybe this will help someone....
I'm 80% sure this has to be cuz of stock charger

did you try first just holding down the power button for like 10+ seconds? I get the red blink of death a lot in my car, I believe it is related somehow with thw wireless charging and it is shorting out or something with another component of my car. Anyway holding down the power button for a while reboots it.

And then the other 1000 that weren't charging or did use a different charger.
I don't believe it's the stock charger
I tried 5 different wall chargers (including stock charger). Three different USB cables on three different PC's. No change in results. Red blinking LED remained. I tried all combination of powering it on...Red blinking LED remained. I literally tired everything for 4hrs straight without any results.
Removing the back, disconnecting battery and reconnecting did the trick. It has been working perfectly for 6hrs now. Charges fine, no issues.

Very easy. Took about 3 minutes. I also had access to cell phone tools...basically a plastic separator tool (wont scratch or brake anything). You could also use a guitar pick or a plastic silverware knife.
I just received a Nexus and it is doing this exact thing.
I plug it in with my Samsung Tablet charger (2.0a so plenty of power) and get a SOLID red LED. After about 5 minutes, the Red LED turns off. If I try to power it on (power, vol down and power, all 3 buttons) with AC attached the Red LED just comes back on solid. Unplugged, nothing happens - no matter how long I hold down the buttons. Nothing is working!
Did I get stiffed with a crap device?

Unfortunately I purchased this from ebay - just my luck it comes back in the play store the week I finally get one at a decent price! I'm going to leave it charging overnight, but I don't have high hopes. I'm really bummed out.

you gotta carefully take the back off and disconnected/reconnect the battery. that's your only hope.
I noticed my Belkin car charger started wheezing and the phone displayed the charging icon on and off. But disconnected before anything happened..

If you have paid with paypal check if you have buyers protection.
Then first contact the seller and if he ignores you then contact paypal about the issue.

I'll have a try.
Did anyone tried to not panic and just put the phone for a couple of hours into charger?
if the battery is completly discharged, connecting it to charger for 10 mins will not make the device run, trust me it works the same on Nexus 7.
Put the device to charger for at least half of day (6h) and then check if the problem still appear, if yes then RMA the device (openning it up may break the warranty).

This isn't the problem in a lot of the cases. I've had it happen to me now 10+ times. Sometimes the battery is almost full-charge. I can't RMA the device because I bought it at home (Wisconsin) and now I'm living in Germany.
For anybody wondering, you can buy a nexus from somebody else (as in the e-bay case) and transfer the warranty to your name.

This a "lot" of cases, are simply people who panicked and cant think straight (this is most common issue at Xda developers, especially when rooting phone ). The long charging test is the first thing you should check, if this will not help then its battery fault and need to be RMA'ead. But in most cases i'v readed , it was simply that battery was discharged fully, and phone needed time to charge it back to run device...
You still can RMA your device, it will just cost u more to send/recieve it from Google/LG.
And yes, if you bought a N4 purchased at google play and sold to you, the device ID must be transfered to new owner (old owner can simply send an email to google play). In case it will not be transfered and you will try to RMA te device, the original buyer will get it , not you.

The way the story goes:
My girlfriend drops her N4.
The screen breaks and I replace it.
About two weeks pass and she gets the red light of death.
I do some homework, read few threads, watch few videos and try everything I found before I take device apart again.
Try pushing all the buttons I read about, while plugging the charger, while unplugging and standing on one foot and singing "Mary Had a Little Lamb" and other voodoo. No success.
Taking the back cover off and unplugging the battery. Connecting it back, closing the N4, try to power it up but no signs of life.
Suddenly I realize the device is very hot. VERY hot. I start taking it apart again, unplug the battery and let it cool. After that I plug the battery back again leave the back cover of, to check if the powering up process made it so hot. Well, no. After about 15 seconds I begin to feel the heat.
I decide to blame the battery from my own N4. I take my own N4 apart, try to get the battery out, but while doing it I damage the battery and it starts smoking. So now my device is officially dead too. My N4 battery goes to the trash and I think "whatever... I'll try her battery on mine.". I plug it in and the N4 stays cold for few minutes, I close the back door and it powers up flawlessly and now runs for few hours.
Since I she bought the N4 in the US she had no warranty here where we live, so that's the reason I changed the screen myself which voids any chances for RMA even if could figure a way to get it back the the US.
Meanwhile I ordered a new battery for myself.
Do you guys think it the logic board that's dead (If so, should I replace it?)? Maybe other part that just does short circuit? Maybe the battery got f***ed during the screen replacement and it just took time to kill the entire phone with overcharge or something? Any other ideas I didn't lay my mind on?
Thanks in advance for your replies!

so judging from your experiences it is not a dead battery that causes the red light of death problem?
i am wondering because i too have red light of death on my 2nd batch nexus 4 (ordered 11/27/12, delivered december 13 2012) and i too took it apart and removed battery for charging, this did nothing but i have a new nexus 4 coming from rma and i would like to swap the batteries and see if that will help because i would like to wipe the phone im sending back but idk if thats possible

I ended up getting a used motherboard from ebay for about 100$ and replacing it. Still works like a charm.
But I can't promise you anything, since it may be any other part that causes a short circuit and burns it. I just took my chance.
For me unfortunately the RMA wasn't an option.
I am having problems with my Nexus 4.
History, replaced screen after phone was knocked out of my hand, probably damaged battery while trying to remove it, but everything worked once it was back together.
Screen broke again, and while working on that, I noticed the battery had swollen so ordered a replacement of eBay.
All back together now, but.
1 Phone does not state "charging" when connected to AC or USB charging, although the battery icon has the lightning bolt in it and the %charge does not drop while messing with the phone.
2 Phone does charge using wireless, but slowly, and status swaps back and forth between charging and not charging and the % will move from e.g. 40% to 35% as it says charging or not charging.
3 USB works for connection to PC.
I charged the new battery overnight, wirelessly. It got to about 90%, so slow charging, but seems to work. Phone is usable, everything seems to work. I connected it to PC and was able to use Nexus Root Toolkit to backup, the reset the phone, no change in charging behavior.
Booting into safe mode made no difference either. So it seems it is not software/firmware/apps that are causing the problem?
I guess next step is to open it up again and remove and remake all connections and check contact posts? Should I order a third battery? Or a new motherboard?
I searched here, but could not find anyone with the same problem.
Any and all help appreciated. Thanks in advance, guys.
Opening and rechecking connections and coating with contact cleaner has made no difference.
Phone typically needs Volume Down and Power button pressed to get it to start, then Power Button to select start option, then seems to run okay.
Battery still not reaching 100% charged, generally 70-80% after a full night off, using wireless (my Nexus 5 charges happily on same charger).
Ordered a cheap battery from China, not really expecting that to be the problem, but no other clues or suggestions for now.
Any update?
My battery is ****e now, lasts 3-4 hours and I need to turn off the phone and charge. It takes 4+ hours to charge when switched on. Charging via the PC you can forget it, it drains the battery if anything!
I'm thinking of buying the battery on eBay and doing my research on how to fix myself.
Phone not switching on and Battery issues
Hi,
I have been facing quick drainage of my Nexus 4 battery since past few months. Recently I had been keeping it on charge almost the whole day, and a full charge would last only 2-3 hours! Further, the charging was taking a lot of time too.
Today, my phone had already switched off due to low battery when I put it on charger. After the white charging icon appeared for a few seconds, the phone wasn't charging at all. I have tried 4 different chargers, but to no avail.
Can someone help me? Is there a guide on how to change the battery?
Any help and urgent help appreciated!
Zany!

It's possible some hardware was damaged when you took apart and put back together your phone. The USB board is a possibility, as is the back cover itself. These parts are pretty inexpensive, if you want to try buying a replacement, but that's just a shot in the dark.

Buy a new battery. Li-ion batteries are only good for a few hundred cycles or so (~500 cycles is the expected lifetime), and the N4 isn't exactly the best in battery life, so you can reach the point where your battery turns to crap within a year or so (or less).
Go to ifixit.com and look at the teardown. All you need to replace the battery is a T5 TORX driver (for the screws at the bottom), something thin and plastic (like a guitar pick or a plastic knife - they do make professional tools for this) to pry the back cover off, a tiny phillips screwdriver (like for eyeglasses) for the battery screws, and something to pry the old battery off of the adhesive holding it in. Double sided cellophane tape works fine for keeping the new battery in. When prying the cover off, go slowly. A little at a time, don't rush or force things. Or you might flex too much and crack the back glass. Don't forget to take out the SIM tray first.

Today, my phone had already switched off due to low battery when I put it on charger. After the white charging icon appeared for a few seconds, the phone wasn't charging at all. I have tried 4 different chargers, but to no avail.
Can someone help me? Is there a guide on how to change the battery?

Time for a new battery. See above.
My battery have started to swollen up a bit but not alot (around 1mm or less, but it is noticeable when not in a case, it can wiggle a bit from side to side but not alot at all).
I have already ordered a new battery if it is expanding more, but yet battery life is pretty good in standby but not getting more then 3hours of SOT. but since im mostly using the N4 for email's and texting its not a problem for me to get through a full day.
I'm having the exact same issue but I've never taken the phone apart. In the 20 minutes its been off charger it's dropped 11% screen off in my pocket. It also gets hot and shuts off.

That could be software/ROM related. It sounds like somethings keeping your phone going full blast instead of letting it idle.
Yup, trying going back to full stock (should always be first step if possible), and then you can go from there. If it doesn't happen, than it was a software issue, and if it still does than it is definitely a hardware issue. Best of luck.

With a swollen battery I strongly recommend you stop actively using the device. Swollen batteries can explode and that would not be good at all. I advise you to please not use the device anymore.

Third battery (original, suspect replacement, now China sourced replacement) has been working well, phone back together and preforming as new for the last few months
I've been having a few issues with my Nexus 4 on 5.1.1.
Twice in the past month I've had random Force closures of all aps. Facebook was the worst. But then it goes on to all other apps including the launcher.
First time that happened I did a factory reset and things went well. Yesterday it happened again while it was on another charger and I can get my phone to boot.
The screen backlight looks like is on when it's plugged into the charger and will go out if I hold the power button down for 5 to 10 seconds.
If I hold the power button down for 10 seconds when the charger is connected the LED flashes red till I take my finger of the Power button.
I've let it charge overnight (12 hours) and I've tried holding both volume buttons with the power button.
As well as Volume up and Volume down separately with the power button.
Is the phone dead? anyone got any ideas on how to bring it back to life
I've got a screwdriver set on order as I don't have fine enough star screwdriver to remove the internal battery connection. Which is my next step..
I think you are right to try replacing your old battery. Be careful while scraping it out where it is glued in not to tear it up too bad because it can 'splode. Might want to use a plastic card for that. I used a metal shim, an iOpener, and am much better now...

I'm going to try just unplugging the battery from the board first before I attempt to replace it.
Think it's time for an upgrade anyway.
Got my eye on the "OnePlus-X" as my next phone.
Removed the battery and stuck my multimeter into it.
It's got V output of 3.61 volts but amps drop off a cliff to zero as soon as I touch the contacts.
New battery arriving tomorrow.

I went into recovery mode and did a fectory data reset and wiped all the cache. Pliz help me proceeed. I kind have a hunch that its a software thing. did yours start working ater change of battery?

yes dude. i can go to recovery without it even being plugged in. I m pretty frustrated. I plan on giving it to the repair centre but he will charge me a bit high. Doesnt matter will let you guys know if I do find a solution.
Well my "new" battery arrived yesterday.
And it's getting sent back today!!
Got it through Amazon and when the battery arrived it looked ok but would not charge. I took it out to check the contacts and the ribbon came away form the battery! Looks like it was not soldered to the battery properly (if it ever was!) Just glad it didn't cause a short and kill the phone or myself.
Getting one from a different supplier tomorrow. Hopefully this one will work!

Please let me know! I've ordered a third battery just now. The first one was an aftermarket one, the second one was apparently a knock-off, this one was smaller than the original one.
The third one is hopefully a genuine LG one since the reseller is listed on LG their site.
Dam!!
Replacement battery arrived today. Looks good.
Installed it and the same thing is happening!
Screen backlight goes on. does not seem to be charging!
Now thinking the motherboard is buggered!
But I'll keep the phone on charge overnight just in case...
Damn that sucks to hear man. Hope it works tomorrow!
Now just searching freebe sites and eBay for any damaged cracked nexus4's I could scavenge from
