thanks for the info, yep its in there and clicked together, still not charging properly, i think its a dead battery issue

Have you tried using a different charger or tried charging through your PC to eliminate potential problems with the plug and cable? Just a thought.

Try to jiggle the cable in certain directions such as up down left right and see if it starts to charge. If it doesn't, return the sucker.

I have found the N7 is picky with cables' the default one that comes with it works fine but doesn't seem to want to charge through my car charger.
My epic4g cable doesn't work and neither do any of my other USB cables.
Same with the charger, it has to have a dedicated live connection and no USB splitters with multiple ports.
I need like a good 4-5' USB cable to use tablet comfortably while charging.

I'm using a white 5ft cable I bought f/Amazon for my kindle fire.

Works great on the Nexus 7 as well.

I am now having similar problem on 16gig. It will not charge from the power adapter at all, but will charge from a PC using same cable.
Same behavior on my alternate cable that I use for phone.

My car charger doesn't work either but my computer/tv/printer/tivo/wall/everything else works just fine... it must be a voltage issue with the car charger.

I remember reading that the charging issue some of you guys r having is a confirmed hardware problem, due to poor quality control. Asus was in such a rush to get the first few batches out that certain faults made it into a select number of batches. Other people who have had this hardware problem either could only use the Asus adapter, or that might not even work. You should try to get it replaced by your seller. I'll post the source in the morning if everyone's too lazy to Google.
Cheers

possible fix
I've read on other forums that it is the usb port. I my experience it is a intermittent connectivity or the wall wort isn't putting out enough amps. I bought an iGo Green for the iPad, put the tablet in Airplane mode and it will work fine while using it. Last night I shut it all the way down, let it charge overnight and woke up with a full battery.

Seems like only high output chargers work. All my 2.1A chargers work with Nexus 7, but lower output ones do not charge even when Nexus 7 says it's charging.

My 8GB arrived Monday , 1/2 charged pluged in to the 2A charger it says its charging but the battery just drops. Turned off and left overnight and its still no more than 20% charged.
I need to find an app that shows charging
check output of charger, check cables, check charge on phone vs tab then send back to Google for a replacement grrrr

I have the same problem, how do I fix? I have the 16 gb version.

The N7 seems to be having a lot of problems with charging. A couple times when my battery has been completely dead, I have had a tough time getting it to begin the charging process. One time I watched it begin to charge, then boot up, stay on for about 20 seconds, turn off, and then not charge. I have no idea what's going on. I always eventually get it to work, but something doesn't seem right.

Remedy
Google Play telephone support had be factory reset my Nexus 7 8GB. After the reset, the battery began charging. A major nuisance having to redownload everything, but it does work. Good luck

My Nexus 7 literally takes hours to charge

My Nexus 7 battery takes forever to charge. And this is even when I use my stock cable to the wall charger. I know it takes around 3-4 hours to charge it from dead to full but for some reason mine is only HALFWAY full at the 4 hour mark and I usually have to leave it on the charger the whole night/day for it to be fully charged.
I have no other defects on this product except for this one. And I never dropped it or anything and I'm currently running 4.1.2.
Please help. I know I can't be the only one with this problem.
Definitely use the oem charger (2 Amp compared to 500-850 ma for most) and the supplied USB-3 cable. It will charge faster. After the long initial charge up to 100% mine has been charging pretty well. If I'm down around 10% it can take up to 4 hrs to charge, but the battery is huge compared to most phones. It sounds like something isn't working normally for you. Have you tried turning it off, then charging?
Yes sorry I was unclear in the original post. I'm using everything stock when I charge my Nexus 7. I don't use any other cable. And yes I completely turn it off when I'm charging but yet it still charges horribly slow.
I would test another comparable charger just to make sure it's not the charger or cable itself.
There is a lot of threads that talk about the charger and the possible ones you can & can't use (Nexus 7 is picky). I use a HP Touchpad USB plug and a cable. It does the job well :good:

Do you keep it on while you're charging it? If so that will definitely make it take longer to charge since it's using power.

I keep mine on, so I can check the % on screen. And long as you don't use it while it's charging, it won't take longer.
Trust me I keep everything that I charge off so that it can charge faster and not be using any power while charging. It seems no one else has gone through this from this thread though. It sucks that I have to get a new charger when the stock charger should be still working fine and perfectly.
As far as i have read the informations on / in box. It said to use the OEM charger only. I didn't really measure time when charging, but it always took maybe 2-3 hours max to charge the device completely.

Nexus 4 charging (USB) when plugged into wall?

Hey guys, noob here. Tried to thoroughly research this issue before posting but I cannot figure it out. When I first got the phone I fully charged it with the wall charger and it charged at normal speed and when I went to the battery menu it said charging (AC) Later on I plugged it into my computer so that I could put some music on it and ever since then when I plug it into the wall it says charging (USB) and its slow as hell to charge. Basically unusable for day to day use. So far I have tried multiple chargers, factory resets, and restarting the phone with the charger plugged and unplugged. Also, when I plug the phone into the computer now it just charges and does not show up as a device or anything. I have contacted Google about a replacement, but god knows when I will get one. Any help would be greatly appreciated!

Bro, the PC USB output is much less than 1.2 ampere output provided by the wall charger.... Lessee ampere means slow charging.... Charge with wall charger
Sent from my Nexus 4 using xda premium
Sounds like there is a setting for the USB connection like with the HTC Flyer where you tell it the kind of connection you want to use. Whether you want connect to pc or charge only. For the Flyer it will charge a little when connected to a computer but if you want to just charge it via the wall charger you need to select charge only.

Did you even read his post? The phone thinks its charging over USB when its plugged into the wall and is charging slowly. Something is definitely wrong.

Sorry I guess I should have phrased better, I am aware that USB charging speeds are way slower but the issue is that when plugged into a wall charger, the phone thinks it is charging through USB and charges ridiculously slow.
Is this happening with the charger and cable that came with the phone? If so, I'd try to RMA it. Google should have stock to cover warranty purposes.

Yep. Happening with the stock charger any every other one I have tried. Got an rma for it and the shipping estimate was the 25th but now it switched to pending. Don't know if that is good or bad
Try a factory reset, settings > backup & reset > factory reset. Missed it in your original post but it wouldn't hurt to try it again if you're gonna RMA it.

Get a multimeter. Check for continuity on the middle two contacts of the USB charger. (While unplugged)
You should have continuity. If you do, blame the phone. If you don't, blame the charger.

Mine says USB right now. It must be temperature based. Odd they would change it from AC to USB. I would have gone the warning message route. E.g. "Stop using your phone if you ever want it to charge. 'AC - slow' charge now enabled."

Or borrow another charger to test the same issue. You could even see if it's the cord or adapter by swapping them as well.
I let my phone cool off. It went back to AC charging. Definite temperature issue. Just odd is says USB/AC and not hot/cold.

Glad you guys are able to solve your charging problems. My problem definitely goes deeper than a heating up issue. I have left my phone on charge without use for hours on many different charger setups (mix between LG, Motorola, and stock adapters and cables) and cannot get it out of USB mode. Still No sign of my replacement phone either. I also cannot get more than 7 hours of battery life out of the thing even with data, GPS, and sync off and screen on the lowest brightness. I think I just got an all around lemon /:

[Q] Nexus 4 Charging Very Slow

I am not sure if anyone else is experiencing this but I am seeing that i'll charge my phone for somewhere between 5-8 hours using the original wall charger and cable but it will not fully charge. It gets to about 70-80%. Is this happening to anyone else?
Any other details? Rooted? ROM?
My phone fully charges from 10% to 100% in about 2 hours or less
Sent from my Nexus 4 using xda app-developers app
5-8 hours is definitely not normal. It fully charges from 0 to 100% in 3h 45min Max and even that is a little bit of a stretch. For me its more like 3hours.

Check your chaging status. If it says USB, thats your problem. Without further knowledge of your setup, I cannot advise you any further
Just happened to me, plugged into original charger before going to sleep, woke up and it shows only 80%. Plugged into Samsung charger, now up to 90% in 20 minutes.

Stock everything. It's happened about 4 nights now.
I find that sometimes my stock charger detects as USB instead of AC. You can see if it is charging that way in the battery details in the settings. When it is stuck on USB it is way slower.
Sent from my Nexus 4 using xda app-developers app
Yeah and if you want it to charge a little bit more faster you turn off the device
Check about phone, make sure it says Charging (AC) and not Charging (USB). If it's USB then thats the reason why, use another charger.
My stock charger that came with N4 went to USB but then for some reason, after I replugged it, it went to AC and has been AC ever since.

I'm not entirely sure wether this is a "good" answer but are you charging by USB meaning plugged in your computer or laptop?
Because I've had it with several phones that if you put it in your laptop it doesn't charge or very very slowly. In the PC it goes faster but not as fast as straight from the wall.
Try plugging the charger in a wallplug, see if that helps? And also if you really want to charge by PC, flash a kernel (see Franco's thread) and put it on "Fast charge USB", then it should go at the same speed as wallcharged. (dunno how on stock rom)
-------------
If you meant that you've charged by plugging it into the wall in OP, then I'm sorry, I don't know Or just a faulty charger.

Do you have a custom kernel installed? Maybe there is a faulty setting in there. Worst case scenario is RMA, but try having the phone plugged in and then power the phone down. Once it's off, press the power button (don't hold it) and see if a battery animation comes up. If it does, then keep it plugged in for a few hours and see if it charges any faster...
try a different cable. For me, the cable went bad. when connected to the oem wall wart, my phone would sometimes be charging USB, sometimes A/C. After changing the cable (not the wart), always charges A/C now.
Install a battery utility and verify how much current it is drawing.

Nexus 7 charging seriously slowly

My nexus 7 has had charging problems before but they seemed to fade away and I was using it perfectly fine until recently it seemed to refuse any charge from the AC adapter. So I connected it to my PC and it went up so slowly over 10-15 mins to go up 1% which is far too slow. I'm still using the original adapter but a different cable and I've tried other adapters as well and they would charge my device incredibly slowly as well for 30 mins before refusing any charge. I've tried everything XDA and other sites have recommended but the problem is not quite the same as mine. Is there anything I'm doing wrong or should I buy a dock if its a faulty OEM? Any help is much appreciated.

Try switching off and charging by using the original adapter and cable!
It still doesn't seem to be charging. Any other bright ideas?
Sent from my LG-P880 using xda app-developers app
Had a few problems with charging mine. I found problems can occur in pretty much any aspect, so test each one by changing it if you can!
Kernel, ROM, charging adapter and USB cable.
If none of these work, its probably the charging port/connection in your device. Have a look at it closely to make sure the connection is as secure as it should be.
Failing all of these, pop the back off the device and take another look at the connection. My port somehow seems a bit larger than my cable so I force it a bit tighter every week or so - possibly bad in the long run but definitely works for now
