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!
I'm charging my phone for the first time on my PC and it's taking forever also.

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

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.

My nexus4 yesterday have the same error, only charge USB mode (original 1.2a , sony 1,5a and samsung 1.0a chargers) but today charge AC mode
May be when is hot only charge in USB mode?
Thanks guys, I guess I will try out the multimeter thing and report back. Finally got a full charge into it over night so maybe that was all it needed. I will report back with any solutions I find in case anybody else develops this problem.

Now my nexus start charging AC mode and then, randomly change to USB mode.
When the device is wireless charging on what mode is, USB or AC?
Sent from my Nexus 4 using xda app-developers app
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."
Sent from my Nexus 4 using Tapatalk 2
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.

Finally I have found my problem, was the original LG cable, with other Samsung usb cable works fine and always chage AC mode.
I have phoned to google support and don't change the charger or cable only, they change all the box (phone and charger)

This should be the better way. 2€ isn't worth to wait three weeks for a new phone...
Just mi thougths

Yes of course :good:
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 /:

Since I upgraded to 4.3, the charging time has incresed up to 8hrs. I flashed the latest rom 4.3Y but It didn't work. How can I fix this, please help. Thanks

I realize this isn't exactly a useful answer, but I've always noticed a slow charge with mine. Now on 4.3 it's even worse. Maybe it's just the norm.
Does anyone else think so?
Dont think so. Mine is charging w/o any issue. It should be the problem with the mini-usb socket on your N7 rather than 4.3.
what an usual charging time should be? I mean wall charger, all stock?

mine is about 2h30'
here is around 6 hours.. regardless of the usb cable or ac outlet. I read some other post where resoldering the usb socket on device helped. I am thinking though of sending it back if doesn't work properly from the start, it's only 2 weeks ago I bought it
Sent from my HTC One using Tapatalk 4
Yes, it should be problem with mini usb socket.

Well maybe the ROM or the USB cable, try to charge with another cable.
Try to wipe Battery Stats (in recovery mode)
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?

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

Has there ever been a cause figured out for the USB charging bug when on AC? I'm on stock 4.4.2. Not rooted or anything at the minute totally stock. It happens with my proper nexus charger that came with the phone and happens with other chargers too. The phone charges stupidly slow when it thinks it's on USB.
Oh and rooting and installing a kernel with fast charge isn't the answer I'm looking for thanks.

Hi so my nexus 4 is charging very slowy, I've this phone for 1 year and I don't know what's happening...Also that might explain (why but)...... if its because of my charger or what. But I need help like I'm just wondering why this is happening? Thanks. Also I don't know if this is happening because of the 4.4 update or something lol?

Apparently something is wrong if you see it charging slowly becoming ever since day one, I've felt that it charges really slow!
The only way to test your theory is to downgrade and see what happens. (as far as the upgrade is concerned)
If you have another charger, obviously that would help as well to see if the n4 charger is shot.
Sent from my Nexus 7 (2013)
I have recently started seeing this problem as well. I even tired a different kernel thinking maybe that would solve it, but to no avail.
I will try with a different charger and see if that would help.

When you go to the battery history (from quick settings for example), does it show (constantly or alternating) USB charging when lugged to wall socket? When i had this, i changed my USB charging cable (the charger is ok but the cable died quickly)
Charging slow is usually due to the charger, try another one that is at least 1A output (original charger is 1.2). Nokia ac-10x is perfect and pretty cheap.
Other causes can be bad charging port or sometimes even a battery drain caused by software.
Whenever you plug in the charger make sure that your Phone shows "Charging (AC)" in your battery setting. If it says "Charging (USB)" then unplug and replug it again. Keep doing until it shows "Charging (AC)"...... On USB charging it charges at 500mA which is half the charging speed of AC charging. I had this issue and I am doing the same to charge it quickly. It doesn't take more than 2h 15mins to charge.
