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!

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)

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 was having a problem where mine, with the charger that came with it would charge very slowly, once overnight only got to 80% in ~8 he's i watched it and sometimes would not even show charging on the lock screen. I switched to my HTC one s charger and it is charging with great speed. Issue with these chargers?

did your HTC One S have an adaptor like the Nexus 4 or any other phone now a days... I think thats the probllem. having an adaptor from USB to AC PLUG messes with these phones. Like I said before, above post.. buy an LG AC Wall Charger.. works great.

Hi,
What is your charge time?
Mine is 2 to 2 and a half hours.

Which battery and/or charger are you using? After coming from the S2 I have noticed a large decrease in charging time with my S4, so this is very surprising to me.

Well I tried charging from my computers use port at work today only rise 20% in 2 hours

...*facepalm*. You're not using original charger and you're complain that the one you use doens't works so well? Do you know that original charger is pulling 2000mA out, while your usb-port is pulling between 300mA and 500mA (depends if it front or back usb-port and the quality of usb port). Do the math, 2600mAh battery and 300mA / h. Full charge should take: 2600:300 = more than 8.5 hours.
With original charger S4 recharges from 0 to 100 in 1h 49minutes. If you take a solar charger it will charge even slower (like 48 hours for 0-100%).
Next time try to use your brain before complaining.

Your Samsung power brick has the cable physically attached to it? If not, you can just use a longer cable with the Samsung power supply.
The included power supply is 2 Amps, whoever is getting long charging times, make sure you use either the original Samsung power supply, or comparable in amperage supply.
Mine charges in 2 and a half hours.

Mine takes 2 to 2.5 h to charge from 0 to 100 percent. You should only use the new white charger, it's more powerful than the black one from s3, it's output is 2.0A ,old one is only 1.0A. Newer use other chargers as they may mess up your battery or phone.

I have to check the amps but based on google the Nokia Charger is at 1.3 Amps. I need to remind myself to switch the short Samsung to longer Nokia cables.
Is it safe to get a higher Amp charger, the one that the iPad uses to charge my S4? No drawback execpt for a faster charging time right?

Take it this way, grilling meat takes for example 45minutes to cook completely. You take it to some powerful furnace like 2000degrees for 5minutes then what do you expect from it to give you back? Well cooked meat or some burned meat outside and maybe raw inside?
Sent from my GT-I9100 using Tapatalk 2

put it this way... the s3 comes with a 700ma charger. it charges a bit slow. and has a 2100mah battery.
the s4 comes with a 2 amp charger. thats 2000ma. it doesnt charge slowly if you use this charger. i personally am going to pop it on this charger when i get home from work and then keep it on my 700ma charger overnight... no reason to waste that powerful output, it will simply waste electricity.
make sure:
1. you use the charger that came with it
2. you use a cable thats as long as (or shorter than) the stock charging cable. longer usb cables tend to charge the phone slower.
also keep in mind usb ports charge any phone slowly. the s4 will charge even slower on them because the battery is oversized compared to most.

I'm using note 2 charger and if I surf Web while charging, literally it is not charging at all.. battery is not going up or down.. Note 2 was not like this.. i could charge battery even if I play 3d game..

Yh so basically when im
Using my phone whilst charging it charges downwards.

It doesn't charge downwards. It's simply because you are doing something so intensive that the power from USB outlets cannot cannot draw enough power and so it compensates by using battery power as well.

seriously?

USB charging is only about a 1/5th of the power from charging from a power point.

Are you charging via the included Samsung charger or computer?
Computer USB only gives out about 0.5 -0.7A @ 5V which is not really enough to charge the phone while in use for anything.
For me, battery will drop even with the screen on.
However, USB charger gives 2A @ 5V which is enough to do some intensive things while not loosing charge.

I have samsung charger with cable (both white) and its the usb charger one not the fixed charger one

Try using this app to find out what current you're getting from your charger. http://forum.xda-developers.com/showthread.php?t=2076078
Stock charger and cable with stock kernel should show 1200 mah with the screen on. If you aren't getting that, try different cables in case you have damaged your stock one. Beware though... I have found some cheap generic cables perform very very badly. You could have different results with a non Samsung charger, sometimes they will work in a similar way, sometimes the kernel detects it as a PC connection and limits the charging current. It depends on the internals of the charger and if there is any resistance across the data pins.

Not true.
USB charging is ~500mA
AC charging is ~850mA, and with a fast charge kernel you'll get up to 1200mA.

[Q] Note 4 Car Charging?

Hey guys,
I just plugged my note 4 into my car charger (anker charger, oem note 4 cable) and couldn't get it to charge. It charges my note 3 no problem.
I also have no problems charging my note 4 with wall chargers.
Any help?

I've got the "Anker® 18W / 3.6A Car Charger with Built-in Micro USB Cord for Android" and it's actually CHARGING my Note 4 when using GPS navigation and playing music! My Note 2 wouldn't charge, but it would hold charge under the same conditions.
What model charger are you using?

I actually can't find it on the charger itself or even Amazon. It's relatively new, I thought it was a 2.0/2.1 amp charger (2x USB). Definitely Anker though.

Are you using both usb's at the same time? If so, it's splitting the power, so you'll get a slow charge.

and it charges my note 4 while running Waze and tethering my Radar Detector via Bluetooth (which also uses GPS)....and it charges my wife's S5 at the same time

Using an afer market 2.1a charger and an S3 cable, charges just fine.

Will the car charger also do the 50% in 30min charging ?

Doubt it. You need a special charger for that.

I believe Samsung has stated it's a 9v charger instead of the conventional 5v charger.

Did some more research and found this:

From the Engadget review, "I clarified with Samsung that it chose a proprietary solution instead of licensing Qualcomm's QuickCharge tech, but it insisted that you could still use QuickCharge 2.0-compatible chargers to achieve the same results."
