So before I go to bed I always turn off my phone and plug it in the wall charger that came in the box. This morning I woke up, turned my phone on and it only charged to 47!! Has this ever happened to you?
Btw I'm on the march 3 build of paranoid android, faux 7r2 mainline kernel, latest PA gapps and the new bootloader and radio.

I don't turn my phone off but I did have one night where I plugged it in and the charger did not seem to work at all (woke up w/ ~40% as well).
Stock, unrooted here.
Had this happen to me once or twice and mine kept showing its charging after I unplug it. I found it only does this with the stock wall charger so I bought a new 2.1 amp wall charger and now it charges without any problems. I think the stock wall unit has a high rate of defection.

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?

My nexus 4 was all fine till I flashed the r22 kernel.
My phone had about 22% battery left, so I plugged it in to wall, and I started using it at the same time
To my surprise, after 2 hours of being plugged in to wall, the battery has discharged to 19%! And I've been only using Whatsapp with lowest brightness! no heavy usage!
So I left it there to charge without using it, and it reached 95% in about 7 hours! (usually it took 2 to 3 hours)
I reverted back the kernel and the ROM and tried again, with no success! It goes through the same behavior.
Any Ideas? Is something wrong with my device?
are you using the original charger? my nexus 7 discharges while plugged in if I'm using my nexus 4 charger

Could be the cable? Im using its cable but plugged to the pc.
I am suffering from something similar since updating OTA to 4.2.2. I'm using the official charger and always charge overnight but twice in the last 6 days the device has not been fully charged in the morning. Looking at the battery graph it reached 100% in a few hours but then slowly discharged despite still being plugged in. I use the Clock Daydream in Night mode (and always have, since I got the device in November) so I'm going to disable that first and see if the problem exists. If so then I'll try a different charger. If that fails then it's factory reset time.
it is strange that after reaching 100% plugged it in to wall if i use it to listen to music or something like that still plugged to the wall it discharges to 99%.
This makes no sense to me a phone discharging while plugged to the wall
same thing's happening to me. not really that bothered but I want my phone to charge and not discharge when I play music. ;(

Yes, I've had the same experience since the OTA 4.2.2 update. Went from 8% to 1% while running nothing but XDA app at lowest brightness. Stock charger. Never had it happen before update.

That's your issue, your PC's usb only supplies 500-+ mA for charging. The nexus 4 original charger is 1.2mA.
It's the stock charger, it sucks, try re-plugging the cable several times (check in battery, if charing says "AC" instead of "USB)

Once your phone reaches 100% it stops charging even if it's still plugged in.

Until reaches about 80%, then it starts again (not completely sure if it's 80%)

this. they must've "overlooked" the charger lol
Similar issue.
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.
Thanks

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.
Since the update, anytime I want to charge my phone in my truck, I have to reboot it while it's plugged up for it to charge. I only have to do this on the stock rom. It's been this way odex/deodex, multiple flashes.

Mine started doing the same thing shortly after updating and then resetting...mine would only flash the battery icon and show it was discharging from the battery in settings and still the same even rebooting while plugged in my truck...no charging. I have a different charger and swapped them- it works fine. I was just figuring it was my charger, but makes me wonder now...
I'll have to try old the charger on my wife's s4 and see if it does the same.
UPDATE: Nope. Not the phone itself or software causing issue, for me anyway. It was a faulty charger.
I have a none rooted Nexus 10. Just recently updated it to 5.0.1 from 4.4.4. Ever since the update the battery barely chargers. For example, last night the battery was completely dead, so I threw it on the charger. After about 6 hours of charging, it went from 0% to 29%. I know that the charger itself is fine, I used to use it as my charger for my Nexus 5 and it never slow charged it like this. Could this be an issue from the update? I've attached a pic of the battery status.
Just an update, since I first posted, the tablet has been plugged in charging. Reached a high of 33% and is now DOWN to 26%. What could possibly be going on ?
I got the same problem... Slow change.. Any idea?
Hi,
I had a similar issue recently. All I did was use another cable with the stock wall charger. I was using stock cable + stock charger and had these problems, then I picked up my Kindle cable and put on the charger and it was fine again.
Battery had an estimative of 7-9 hours to charge got down to 4-5h.
All the best,
~Lord
