My Nexus 7 is no longer charging while turned on. If I power it off it'll charge with the battery symbol. I can't even get my PC to recognize it while plugged in to USB. I'm using the stock charger and cable. Any thoughts?
I'm currently running Paranoid Android 2.54, however when this started I was on 2.50. I thought flashing a newer version might help.
Not charging
Plus 1 on this issue,
Running stock ROM and it updated yesterday to version JOP40C now it's only charging when turned off.
+1, same here, but now it won't charge as the battery got completly drained.
Still does not charge. This is a launch N7, curious if Google will replace it.

I just received a replacement seven this week for the same issue, mine stopped charging. I called google play customer service, and they didn't give me a hastle at all.
Were you rooted/running a custom ROM? I am, and with my N7 not getting recognized I feel like flashing back to stock might be problematic.

yea, rooted, custom ROM and kernel. doesn't matter though, it just started one day randomly. I finally did get it to charge BTW, by giving it a few firm smacks on the back. they didn't even ask if it was with root or if it was a custom ROM. if its hardware related, it won't make a difference. i sent it back with twrp recovery, rasbean jelly rom, and trinity kernel. i did wipe the data and the storage before i sent it in.
Yeah my Nexus' charging is messed up since 4.2. Battery seems to run down extremely quickly (around 30% in two hours with Spotify on and general browsing.) Plugging it into the wall with the official charger sometimes charges it EXTREMELY slowly, and sometimes just says its charges and still the battery is running down.
It happened to charge last night, and over the course of around 10 hours, I think I had 60% battery. Trying to charge now, and nothing, just losing battery. No idea what the issue could be. Tablet completely stock.

+1 on this issue. N7 isn't charging when turned on, no charging issues if turned off. It isn't recognized when connected to a PC. Whenever I try switching users, the darn thing restarts itself. It does the same thing when I try USB debugging. I am running 4.2.1.
Please help!
Investigated problem
After upgrading to 4.2.1 my N7 charged very slowly. Finally today I decided to investigate it, albeit inaccurately.
Plugging a 2A charger into my 120V power monitor, I noticed the following:
When the N7 was on, the power draw continually alternated between 0 watts and 2 watts.
When the N7 had been shut down from the bootloader (not from the OS) and the cable plugged in/out, the power draw was a constant 2 watts.
The max charging rate of the N7 is around 10 watts.
So it looks like the N7 is will charge either very slowly, or kind of slowly. What I find strange is that this issue only occurs on some devices. Perhaps later devices use a different charging controller?
Either way, would really like a fix for this.

From the way you described your test setup, you seem to be measuring the power consumed by the charger itself on a 120 VAC source. The wattage there should be low, albeit still higher than what you're seeing. Along that line, if you ever see it go up anywhere near 10 watts, then something has gone horribly wrong.
Also, the slow charging seems to be peculiar to 4.2 and above, indicating that it is not actually a hardware issue.
same!
Been having the same problem for a few days now, I was on stock 4.2 and updated today to a custom ROM based off of 4.2.1 and there is still no difference. Anyone found a solution yet?? Its quite concerning especially since I got mine from GameStop in the US then moved to the UK shortly after!
Just wanted to add, before this started I was having the same problem that is talked about here http://forums.androidcentral.com/google-nexus-7-tablet-forum/228706-nexus-7-problem-wont-charge-when-does-screen-goes-dead-pixels-fly-across-screen.html
I figured it was caused by letting the battery drain completely so I opened it up pulled the battery plug out, plugged it back in and charged it till it was full and it continued to work. haven't let it die since.
Same problem here, stock Nexus 7 running 4.2.1, roughly 2 months old.
It charges when the device is turned off, but will not charge when powered on -- started happening about 2 weeks ago (charged fine previously). This is using the stock brick and cable that came with the tablet.
I have to imagine that this is a software issue and that the next one will have a similar problem -- has anyone else swapped one out and had the problem disappear with the new one?

Past 2 days my Nexus 4 is not charging via Car Charger, i have original Samsung Charger, i also have USB port. i tried the USB cable i receievd with Nexus 4 from LG. No Luck, i can only charge my Nexus 4 at home.
I checked my usb lead and Samsung Car Charger to charge my Backup phone Galaxy mini, it works fine. Gaalaxy mini charges but not my Nexus 4.
I was thinking it might be an issue from CM Kernel. i recently installed CM10.1 nightly 13/3/2013 it was working fine before going custom rom. I have used every single custom roms in the past, i had no problem with charging anywhere before.
so i returned back to stock today and it is the same not charging.
I can only charge at home, but i use it alot and i need to keep it on charge in the car too.
Help pls thank you
Lower amp car chargers can't charge the Nexus4 faster than it discharges. I have a 2 Amp charger that works.
Having the screen on full brigthness while using GPS drains the phone really fast!
Does your Nexus4 not charge at all or does it charge slower than it drains?
It might be the kernel, I am using a Samsung galaxy S3 usb cable with a usb port car charger and I do not have any problems charging my N4. I am on Baked ROM and Franco kernel.
it has nothing to do with my car chager cuz it was working fine before.

i did not have any problems before using the CM
as soon as i flashed CM10.1, this problem started. i changed back to stock and still same problem
I'm also having problems with charging my Nexus 4 in the car. I have charged my N4 everyday going to work for the last 3 months. But last week it stopped working I'm also running CM 10.1 nightlies since day one if that has any importance.
The car charger works with my old Nexus One
I have bought another car charger that works(verified with N1), but doesn't charge my N4. Both chargers support 1 Ampere.
I can charge my N4 with AC-adapters
I can also charge the N4 connected to my computer using USB.
Any ideas?
bumping this. any solutions? same boat here
I have same isdue, but not all the time. I noticed my N4 stops charging with my car charger, the original charger and the wireless charger when it comes too hot. (after playing a game for example)
The only way I found to make it charges again is waiting for it to get cooler and then replug the charger. I think it might be an hardware security that stops the charge when the battery is too hot because when my N4 has a normal temperature it charges normaly evdn on my 1A car charger
BIG bump here!! My N4 stopped charging in my car randomly around when 4.3 came out....!! Any ideas what's up?!? Annoooying......!
Just in case I drive a 2010 Prius.... Worked fine since the N4 was first released.

Left phone charging overnight and woke up this morning at 53%.
Using Stock USB cable and ac adapter charging through the wall.
The charger is usually fine and I wake up at 100%. Once or twice I'll wake up with around 73% which is fine.. but at 53%, aint nobody got time for that.
Anyone else have same experience? Any fixes?. Running PA and Franco latest.

Just recently started having this same problem. When I notice it happening, I can see the charging indicator flipping on and off rapidly.
I use an HTC charger from my old desire and haven't had any issues.
Not even took the nexus 4 charger out of the box.
Try a different charger.

I had this problem with the stock charger and cable. Ordered a new (and official) LG USB cable and still had the same problem. Oddly enough, if I use the USB cable from my old Atrix charger with the LG stock charger, the issue disappeared and I have not had it happen since.
No idea if this is a problem with the charger itself, or just cheap USB cables
I had this problem 2 months ago. It's definitely the charger. I replaced it with a cheap travel charger and have no problems.

Stock charger is useless, use a different one... preferably without detachable USB cable. Seems like you're getting what I used to before I changed chargers, "USB charging" when you are plugged into a wall outlet.
for me, the charger was fine. The cable is what is failing. Maybe it wasn't made to usb spec. Sometimes when plugging in, I notice it starts USB charging and not A/C charging. I installed a battery widget that tells me what charging mode it is in so I kept a watchful eye on that. After using a different cable (with same charger), I've never had this issue again.

Are you on stock rom? When I first got my nexus it was on 4.2.1 I noticed that if I left the phone on the charger or was using it while it was charging the % number would go down.
Flashing a custom rom and kernel fixed these issues.
Changed the usb-AC adapter to my iphone one while using the same usb wire and its working fine now.
Mine started doing this yesterday but wasn't using the stock charger. I rebooted the phone and used the lg charger and cable and phone has been fine sine.

I had this issue before where the stock battery graph would sometimes show USB charging even though I'm using the wall charger. It would sometimes flicker between charging and not-charging as well.
I replaced the LG USB cable to a generic micro USB cable from ebay and the issue hasn't repeated ... so far.
So I have a rooted s4 running PAC-man rom on ktoonz kernel but before that I was on infamous alpha and using bioshock 2.0 kernel. Just a couple days ago I've noticed my battery has been really slow to charge. This morning I noticed it was actually losing battery life while on the charger. I tried calibrating it and draining dead then letting it sit.... Well it's been turn off on the charger for over an hour. When I turned it on it was only at 18%. During this time of my typing this.... It's dropped to 17 while on the charger. How can I tell if it's the battery or the charger. I only have one of each so I can't use different one. I've included some screens of my battery. i also noticed when i plugged in my phone to the computer the computer gave me a this would run better using a 2.0 usb.....thats never happened to me before

Try using a different charger first. If that doesnt help try a different rom . also try charging with wifi and screen off
I've done all of them and so far the same result... But i had a buddy of mine bring over his s4 charger and it charged fine..... When i use his die hard calibration says AC plug in. With my charger it says USB..... I'm not really sure how to fix it other than buying a whole new charger

Sounds like there is a cracking in the solder of the data pins inside the charging block. They are shorted together to tell the phone that it is plugged into a regular outlet. What seems to be happening is that there is a faulty connection with them making the phone think it is on USB and making it only pull 500mah.

As a short term fix till I get a new one can I use fast charge with my kernel to trick it into thinking it's not broken?

Three days ago, my phone stopped taking a charge.
Thought it was the charging port.
Yesterday, it was charging but not actively adding battery percentage, ie charged for an hour; still at 8%.
Thought it might be something with fast charge.
change settings. no change.
did a factory reset. no change.
tried a spare battery. no change.
used another spare battery that was charged. watched the battery life drain.
turned phone off. plugged into charge. now the battery icon and the safestrap boot screen are alternating but it takes a charge very slowly. but not while powered on. and the battery is no longer draining so fast.
I guess the next thing to do is reinstall system?
any other suggestions before I do that?
Did you try a different charger and cable?
