Okay, so my nexus 7 got completely discharged a couple of days ago. Now when I try to charge it using an AC charger (even tried the one that came with it) it starts up, then powers off due to insufficient power and keeps repeating this cycle indefinitely. Its not charging up and I have no idea what to do.

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.

Hi all,
Have anyone encounter the nexus 4 charger emit noise when the phone is fully charged?
But when I turn the phone screen on, the noise will be gone and back again when the phone screen is off.
Thank you.

Can you reproduce this with a video?
Sent from my Nexus 4 using Tapatalk 2
Maybe it's a feature?
Hmm.. Will try to take a video. Doesn't seems like a feature. It produce some high pitch sound. When I switch off the power, the phone screen will take some time to wake up, normally it should auto wake up immediately as what I observe from nexus 7.

I realized that the original charger when charging makes the device hot and slow.
But i have a galaxy tab 10.1 charger that keeps it cool and charge fast

My Two cents
I don't own a nexus 4 but mine dies the same exact thing. Usually when the battery is full. My guess is the phone is rejecting the charge. But when You turn the screen on, the charger powers the screen and possibly the speakers, so it stops.

Have you got a old Xperia sitting around? Bring them to us!
Thanks for the comments. I hope my charger don't fail on me. Just want to confirm did anyone use a nexus 7 charger to charge nexus 4? I read through forum, though the nexus 7 using 2A than nexus 4 1.2A. The phone will charge fine without damaging the battery or the phone, since it only draws the amount of charges needed.

Charger buzz not only when fully charged, but the whole cycle
Hi guys, I am using paranoidandroid latest build and Franco M1 kernel. So yesterday night, as soon as I plugged in my nexus 4 for charging, it went from 30 to 100% in seconds and showed as being charged! It happend twice so far and restarting fixed it. But when I restarted, it started charging from 18%.
Is it a bug in the kernel or the ROM? Should I be worried?

AW: Charging went from 30% to 100%
I had that happen 3 or 4 times since January, once on stock rom as well. Unplugging and waiting a few seconds before plugging it in again always fixed it for me. I'm using AOKP and franco kernel at the moment.
Sent from my Nexus 4 using xda app-developers app
That happened to me as well. Both on stock and on franco's kernel. It just seems that our N4 sometimes gets a little glitchy when it comes to reading off the battery percentage. As long as it's not happening consistently, I wouldn't worry at all:highfive:.
Do you have a nexus 7 I accidentally plugged my nexus 7 charger into my four and that happens instantly jumps to 100%.
Sent from my Nexus 7 using xda premium
I'm using the regular charger from LG. Hopefully its just a bug and not something hardware related.
Sent from my Nexus 4
I think its usually caused by using a charger other than the one supplied or when you have just used the usb and then put it into the mains shortly after.
I'm stock and in rooted. Use stock charger. Happened last night to me. Unplugged a few times and it worked. Weird

known bug, im using only stock charger and it happened few times, i used restart and recharged it
Just reboot and charge again
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.

Exactly what it says. How long does it take on average to charge your nexus 7? Thanks.

Using a 2.1A charger and not playing on it while it's charging, probably 3 hours top from 0%. That's roughly what it was with mine about a week ago, I think I have the battery history still logged in battery monitor widget pro, if I do I'll dig em up for exactness.
About 3 hours from empty to full charged with stock charger on mine.
Sent from my Nexus 7 using xda premium
With the stock charger, about 3 hours, maybe a little over.
Yep bout 3 hours here also for a full charge.
Sent from my Galaxy Nexus using xda premium
Hmmm actually mine is charging from 0% to 100% in 3.5-4 hours... weird
I bought the stock dock,and sometimes charging is super slow if I don't get it seated perfectly. That problem aside, does anyone use the dock, and what are their charging times please?
