Since i updated my device to 4.2.1 charging my nexus 7 really get slow..... It takes 6 hours to 7 hours to fully charge. Im using the cable and charger that it came from the unit.
Is there a fix for this one? Thanks.

AW: Is there a fix for slow charging issue?
Check whether the device charges in USB mode. It can happen for some reason I don't know. In this mode it charges much slower. I once had it happen when on AC.
It's on AC. It takes 6 hrs to fully charge from empty. =(

What do you mean by rebooting it? I have the same charging problem. It needs about five to six hours for me to charge fully. How did you solve it? Is it really the problem of android 4.2.2?
Just try rebooting it or restart the device while charging. Im using battery widget reborn app, to see how many hrs left to make my nexus 7 to be fully charged.
Here's what i do,
Plug the charger then check after 2 mins on the app battery widget reborn how many hrs left to be fully charged, if it's says more than 4 hrs or greater than that. Hit the power button and restart your device. Once the device booted up, check the remaining time left on charging if it's improved to 3 hrs or less to fully charged your device.
Try it. It's working fine for my nexus 7.

I tried the app you mentioned. But the remaining time it indicates isn't equivalent to the real time used. Maybe this app doesn't work for my device, it still needs four to five hours for my nexus being fully charged. Anyway, thanks for your reply.

Or you may try to go to bootloader, then turn it off.. Unplug the charger, then put it back in then turn on your device.. It works for me.

I'm having some trouble with my Nexus 7. I foolishly discharged my battery fully. Now, when I plug it in, it boots up immediately, and then powers off with static after a few seconds, so I can't charge it properly. Do you know a way I can force it to charge without booting?

The problem is that for me it doesn't go to the charging screen, it tries to boot, crashes, and tries to boot up again. I'm pretty sure it won't charge much this way and it doesn't seem very healthy.
That's odd um try if you have twrp go there and see if it says the battery is charging, if not can you get into your bootloader okay?

My nexus 7 was fully charged and I put it in the rack in the night. Next morning it shut down completely. When I switched it on, it showed battery 0% says 0% the same c thing happened today as well. Its a new device. Any idea??

Sure.. Here is the screen shot..

Some app or service is draining your battery. Get BetterBatteryStats to narrow it down.

I installed battery saver app.. I will check if it can do any good..

Like someone said before it's a rogue app and the only way your going to get the battery drain issue to go away is to figure out which app is doing it and then get rid of it.

I think the best solution for you is to factory reset or re-install android on your device once.
It will be easier than finding out where is the problem. as screen snap shows most of the battery is drained by "android OS".
It was just my opinion you can take it if you want.
My battery usage. Even though my screen on time was only about 2 hrs most of the battery was drained by the screen. So there music be something very wrong in your case.
I don't know about android virus but that might be an option.

Gonna follow along and disable my daydream as well since I'm having the same problem you are with it actually draining while on the charger (Stock ROM, Franco Kernel, OEM wall wart with gold tipped USB cable). Tis quite annoying to have to either keep the screen off or power down completely in order for this bad boy to charge...
Wow check that out has anyone's device done that? Stock charger, batt went from 50% to full in round 5 mins...?!
Sent from my Nexus 4 using xda premium
Then, after you reboot, the percentage stays the same?
Nexus4 modded with cyanogen.
mine done that once... but it was trolling me.
After reboot? Nah.. it dropped to 28%!
Fastest discharge in history too.
Fail

My N4 did that once even worse, went from 7% to 100% in under 10 minutes, I was do confused. I had to run out so I grabbed it and took it with me, battery went to 97% after about twenty minutes then phone just shut off. Plugged in and had the red led. I plugged in and booted to recovery and let it charge a few, then booted up and it was at 3%, has been fine since.

Do you by any chance have lightflow installed...? I recently had my Nexus 4 going from 29% to 100% in perhaps 10 seconds and I have never seen this before and I have had the phone since december but have just installed lightflow about a week ago - after a restart everything was back to normal though....
No lightflow here...also hasn't happened again either so it seems random.

Im on stock 4.2.2 with Matr1x kernal...mine takes too damn long
This isnt a new device so not the first run obviously... And had this problem on full stock aswell...using the original LG charger.
Takes around 5+ hours to full charge from 25% to 100%
Its not a biggie since i plug this is in before going to sleep and by the time i wake up in the morning (around 7 hours ) its fully charged...but i just want to know is it a hardware problem only in mine?? Or a common issue??

next time you charge, go to the phones main settings, about phone, status.. check if its connecting/charging as usb or ac. usb takes longer to fully charge than ac.

about 3+ hours on the wall charger i guess, 5+ hours if i was plugged into my laptop. try another charger with the right amperage. or try another usb chord with that charger.
Mines about 2 hours wall 3 hours USB...

It only takes 3 to 4 hours to charge my phone by using the original LG charger.
around 2-3 hrs with wall charger and 6-7 hrs with USB.
3 to 4 hours charging from the wall and about 6 charging from USB. I'd suggest swapping out the charger your using and see if that makes a difference.
3.3 hours from under 20% to 100

Seems like it varies device by device... My cousin's nex 4 takes around 5 hours...
And i think ROM and the kernal has nothing to do with it
Bdw im so glad to see such a helpful community here...never expected it

The LG original charger that came with the phone kept randomly ticking from AC to permanent USB charging on the wall. I switched chargers and it stays on AC now.
there's been a few issues with the stock charger, some are inferior to others, I charge mine while I sleep, but my old lg charger is alot better, same with iphone charger
Mine takes more than 3 hours on wall charing

Wall charging: 2h20m from 8% to full of course.

My friend recently bought an imported nexus 4 from eBay(on my advice). He's having a strange a problem. The device works normally till the battery drains below 50%. But then it suddenly turns off and doesn't turn back on again. When he connects the charger, it's stats charging from 0% again. The charging process is also normal.
Anyone had this type of problem?

Whats the rom and kernel?
Sent from my Nexus 4 using XDA Premium 4 mobile app
Try charging it to 100%, disconnect charger, reboot and check if it already lost some charge during reboot. If yes charge full again.
I had something similar (not a total drop, but a fast drop when below 50%) a few days ago and this helped. I don't know why, though.

I think you should try both suggestions.
Also inform us what is the ROM and Kernel he is using.
Keep us updated.
