Battery status stuck at 0%

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.

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.

Nexus 7 Won't Turn On

Hey everyone,
I've tried searching, but no luck, so here's my issue.
My nexus 7 was around 25% battery last night so I plugged it in for the night.
Woke up this morning and the backlight was on, but the screen was off.
When I unplugged my n7 the backlight turned off. Hitting the power button had no effect.
I then tried pushing and holding the power button for roughly a minute, nothing.
I have disconnected the battery and still no response from the unit.
I plugged it back in for roughly a minute as well, still nothing.
Unfortunately I don't have access to a charger right now.
Is it possible the battery is dead even though it was on the charger all night?
Sent from my SAMSUNG-SGH-I747 using Tapatalk 2

Weird.
Just plugged it in to my car charger and it booted up. Battery is completely dead, so I guess with the backlight staying on all night it didn't charge.
Now why would the backlight stay on if the screen is off...

Don't go flashing different roms and kernels now like most of the idiots here, it could just have been your charger being faulty or a bad connection to the tablet overnight. if the problem happens again then you can investigate further.
BTW, were you charging from your PC/Laptop with a USB cable or through a wall adapter? i've had issues in the past charging my Nexus 4 and 7 not charging overnight on my PC

I feel like a broken record but since I've fixed a ton of n7s with loose battery connections, I would recommend checking the internal battery lead to make sure its not loose. Asus didn't do a good job of making sure all n7 batteries were secure and this allowed the battery to shift and pull the power lead out. Some clear scotch tape on the connector and one on the battery (avoid the copper tape areas) will eliminate this problem if that's what you have.

I ran into this problem. Initially, my Nexus 7 didn't start. When I plug in the charger the screen would flicker from time to time but there's no indication of charging. So I decided to open it up to see that the battery cable has loosened. So I managed to fix it and use it happily thinking that it won't happen again.
Since last week, the same issue happened. I thought it was the same issue and opened it up to see that the battery cable is firmly in place. So I got a shock. I removed it and re-inserted it again to see if it fixed it. But nope, it won't turn on. And now it's been a week and I don't know what to do It's nothing wrong with the loose cable cuz now it's firmly in place.
Now when I plug it in to charge, the screen will just flicker (as in the back light will turn on and off in 5 sec intervals). What do you think I should do? I tried holding the power button for 30 secs as well.
I bought this new from eBay and still under warranty. But I live in Sri Lanka. So when I bought it, I had to ship to a friend in the US and had to wait till he came down. So it's not easy for me to ship back and to receive another device. Hopefully I can find a solution to fix this myself.

Make sure that the cables between the battery and the connector are intact and not broken. One or two people reported a broken cable.
Does it boot while plugged in to the charger with the battery disconnected ? You could simply have a bad battery.

I checked again. The cables aren't broken. They are all in good shape.
It doesn't boot when I plug in. Actually it doesn't show anything on the screen. If I look closely I can see static flicker on the screen from time to time. Just like the static in TV but much much less. Like only a few of those in certain places.
When this happened the first time I opened it up to see the loose cable. So fixing that helped it then. But now I dunno what's causing it.

Might have to try a different charger, maybe something stronger. I JUST had that problem with my GF Nexus 7. It wouldn't boot with her normal charger and the screen would flicker like a TV. I used my Nexus 4 charger and it worked.
She had left the battery fully drain for over two weeks and I think the battery didn't appreciate it.

Phone Dead (even more than a brick)

(fixed)I let my phone die because I wasn't near a charger. Now my phone is completely dead. I try to charge and nothing happens. It won't boot with lit black screen....nothing. It's like having the battery taken out.....
any known fix?
edit: (fixed) I waited and nothing happened so a bit after that I held the power button for 40 seconds then unplugged the charge and while still holding the power button plugged it back and the red/orange light came on. I then let it charge for a bit until the light turned off then I powered it on and worked. I experienced the problem once before but it did the red/orange light problem. It had never fully died like that before which freaked me out.

let it charge for atleast 30 minutes

nothing so far :/

i've had the same problem before.. the best method for make sure that n4 works again is simple, just dissasembly the back case and replace batery connector port and replace it back.
just follow Nexus 4 Teardown from iFixit.com
just remove the battery connector port. you don't need to remove all the battery.

Nexus 7 doesn't charge/turn on

Last time I used it I picked it up only to see that it had 2% battery left and before I could get to the charger it automatically shut off. I figured the battery just died so I put it on the charger, didn't see if the screen/battery indicator came on since I have a cover case on it, and just left it there for the rest of the day/overnight. The next day I took it off the charger but it wouldn't come on and still hasn't. I used the original ASUS charger that came with it, tested it on my N4 and it charges, but no indication of it working on the N7. It's been about a week and I've tried all the button holding combinations to try and wake it up. It's the 2012 Nexus 7. I need help.
Also, I've never messed with the bootloader, I am unrooted and running stock. I last updated to 4.3 OTA and I read some of the bogus things that happen after the update and didn't think it would happen to me but the tablet is literally bricked.

I did have this problem once, but it resolved by plugging it in for a few minutes, plugging out, waiting a few seconds and repeat until the screen shows the charging icon. After a few of these, it was working again.

I had a similar issue this weekend. To get it working, I left it on the charger for a few minutes and then while still on the charger I held in the power button and then the battery charging icon came up. I was also going to recommend checking the USB cable but you've already tested that. Still trying a different cable wouldn't hurt things either. Well I hope something in that rambling helps.

last week i got this issue twice. try this method, first plug your charger at least one hour, its okay if the screen just dark (better if you got something like little flicker or flash). then plug off your usb charger, then plug in again, right after you plug your cable press power button + volume down and wait.
maybe it will hit and miss, but this is the only method that i have tried and works.

Agreed with this one.
I had a situation where I was playing Magic 2014 plugged into the charger, but the game is so CPU intensive it drains the battery faster than I can charge it. I thought I had enough battery but at some point the tablet did an auto-shutdown right in the middle of a game, while still plugged in too. This also resulted in some crazy screen flickering and scary noises, which subsided when I unplugged the charger. When I plugged it back in, seemed to be dead as a doornail.
Anyway what worked for me was to unplug, plug in the charger and immediately hold down power+vol down after it went in. This brought me to the bootloader screen and I was able to get started.

Happened to mine a couple times since being on 4.3. Seems not to like getting completely drained. Anyway, after charging for a bit to make sure it had some juice I plugged it into my computer and held all three buttons. It booted into the bootloader. I selected reboot device or whatever it is. Then moved it back to the wall charger to let it get fully charged.

I have been using my nexus 7 2012 for a year now .. it worked brilliant .. but now this horrible issues has sprung in from nowhere .. the battery wont charge up, or rarely it does,, but very slowly. i am running stock 4.4 unrooted . i have checked my ports for dust, swapped several cables and chargers (also used the original charger and cable). but with no luck. Surprisingly the problem appeared suddenly, one day it charged normally , the next day i left it on charge at 60% and returned to find it on 59%.. help me .. this is driving me crazy

Install the Battery Monitor Widget - should give you an idea of charging/power consumption. I'm assuming you've tried using the stock charger and cable?

I think your battery connector is messed up. U might have to open your tablet and disconnect then reconnect the cables.

]I too have this same issue....
I have the official dock and never had any charge issues until yesterday....
While it's in the dock, it clearly shows it charging and yet the battery meter appears to be losing charge...
I have tried with the original cable and plug among other cables and yet nothing...
The only way for me to get charged is to turn the unit off and yet it still charges painfully slow...
Anyone with a solution other than opening the thing up and hoping it's the plug?
I am running 4.4.2

Mine's having the same problem. It seems to be a hardware problem.. It's charging very slowly or can't be fully charged.
* I have other devices running 4.4 without charging problems.

Mine started with the 4.4.2 update....
It's very strange... If I turn it off and charge... it charges (again) very slowly.... 3 hours and I went from a 2% charge to 59%...
Doesn't matter if I use the dock or plug it in direct.....
So, to me... I would say a software problem... I just don't want to do a full reset and re-install if I don't have too...

my wife's was all the way dead today after not being used and wouldn't turn on. left it plugged in for 30 min and it powered on with only 2% battery. i t is stock unrooted and everything was all good until 4.4.2 is now charging very slowly. I switched to a non oem usb wire with the asus charger to see if it helps. it is the only stock android in my home (out of 7 devices) and I plan to keep it that way for now.

I've been having this issue for about a week and its not fixed. Anyone here can link me to the post where the guy DC/rc his cables? I'll try anything

N7 is very easy to open and close back.
I had the EXACT same issue 2-3 times this year and disconnecting the cable and reconnecting it back fixes it EVERY TIME.
The battery cable is short and the battery is loose so movement pulls the cable out. Not all pins are touching so it results in poor contacts or no contact at all.
Its a design flaw that can also be fixed by sticking a folded paper under the battery.
Voilà!

Tried unplugging and replugging but it's still the same. I think it's my charging connector though. It randomly disconnects when I plug it into the PC. Tried with 3 different cables even the stock one. But I'm not sure if it's the port or the battery. It charges up to < 60 slowly but it doesn't go beyond that and starts draining. Thinking of selling it and getting a flo instead

Tried unplugging and replugging but it's still the same. I think it's my charging connector though. It randomly disconnects when I plug it into the PC. Tried with 3 different cables even the stock one. But I'm not sure if it's the port or the battery. It charges up to < 60 slowly but it doesn't go beyond that and starts draining.

Just a thought, but another possibility is that the ribbon cable to the USB/headphone jack flex assembly has worked loose to the point of intermittent connections. See "step 10" of iFixit's N7 teardown
Or, if the connector itself is mechanically damaged, maybe there is some way to buy just that Asus sub-assembly. Anyone have a source?

Edit - wow, folks are selling them on eBay for US $50. yikes.

I have the same problem, I purchased a nexus 7 charging dock from Amazon and it charges flawlessly. The dock charges using the 4 pins on the side of the tablet. BTW...The charging dock is under 24.00+ Shipping.
