Hi,
I've juste updated my Nexus 4 to Android 4.3 and I've got a strange problem.
I've got an USB hub that was working perfectly to charge my phone (a little bit slower than a computer USB port or the official charger but still quick).
But now it don't charge. When I plug it the phone doesn't charge but when I remove the cable my Nexus play the sound like when you remove your charger when battery is slow. Anyone has an idea?
Charges fine here.
Did you try another charger?

Yes with the wall charger, a computer USB port or my Samsung power bank battery it works fine but not with my USB hub anymore.
And my girlfriend Nexus 4 is still in Android 4.2 and it charge normally.
Like if Android 4.3 need more juice than 4.2. Really strange.
Make sure that you are using the stock charger, sounds like that Android 4.3 needs more power.

This is really driving me crazy.
UPDATE :
If I let the phone charge on Receovery Mode or totally turned off it works perfectly like before.
I've seen on this thread :
http://forum.xda-developers.com/showthread.php?t=2378414
that perhaps it can be the new SUperSU for Android 4.3.
I'm still digging for informations
Mine is doing the exact same thing on latest 4.3.
Charged overnight on my wireless charge pad and it didn't move. Trying to charge it at work now via USB and it still wont charge?
I'll check that link you posted.
edit: I flashed the SU update from CF 1.43 and my phone is now charging? Link http://forum.xda-developers.com/showpost.php?p=43951641&postcount=5

I've updated to the latest SuperSU (1.44) and problem is still here.
Is it possible to be caused by some old files or settings from Faux Kernel from 4.2.2?
I really don't want to flash the full rom and lose all my settings and personnalisations.

Same here. Since 4.3 not charging on usb port when powered on, but charging perfectly when off.
I am still at work and can only charge via my computers usb port, but I expect it to charge normally with the provided charger at home.
Totally stock rom, so no SuperSU or anything to interfere.

Did you format system and do a clean flash

I think you better clean flash rather than unable to charge your phone....Could be the previous kernel messing up your phone

No, I have flashed this zip :

from this thread :
http://forum.xda-developers.com/showthread.php?p=43939424#post43939424
to revert back from Faux's kernel to stock and then I've used the offical OTA to update.
Mine is charging fine after the 4.3 update but I'm running completely stock unrooted.
I'm wirelessly charging using my Nokia DT900 charger as I'm typing this.
Also charges perfectly when connected by cable.
Noticed that I now get a sound alert when the phone is fully charged. I never ever got that before.

Get another charger or get a different kernel. Google likely added this to let phones charge more efficiently and prevent your charger from blowing up (the result of it drawing too much current).

I've flashed Faux's kernel 18 nad the problem is still here.
I'm gonna try to flash a full stock Android 4.3 tomorrow to see if it's a 4.3 problem or "my 4.3".

I currently have an issue charging when hooked to a PC, I was able to disable the "media device" option and then it started charging once I unplugged and replugged in the USB.
Steps to duplicate:
1) Connect phone to PC via USB with Connect as "Media device (MTP)" checked (Settings -> Storage -> Menu -> USB computer connection)
2) See that the phone is not charging.
3) Uncheck "Media device (MTP)"
4) Unplug and replug in USB cable
5) See that the phone is now charging.
6) Re-check "Media device (MTP)"
7) See that phone immediately stops charging.
Same here. 100% stock. No longer charges from wall at night (phone turned off).At 51% in the morning.
I'll try to do a full wipe.
Same problem here

I've got exactly the same problem. Updated my Nexus 4 to 4.3 yesterday. Now at work, I cannot use the USB charger from my work PC any more. Tried with different cables, same result. When I charge my Nexus 7 running 4.2 on the same USB port at the work PC it still works.
Can the Android Kernel somehow measure the amount of power delivered by the USB port and set the icon to 'not-charging'?
When I try a seperate USB charger (delivering 1.2A) it works again.

If someone as some free time and if it's possible (I don't know) can he try to flash the 4.2 stock kernel on the 4.3 ROM. It could answer your question.
After full reflash and wipe still wont load from wall charger when off. Have to try not turning it off at night because it seems to charge if powered on.

My Nexus 7 was working fine up until yesterday. I hooked it up to my iMac at work and copied the latest version of the rom I use, flashed and everything seemed good. I noticed that last night the N7 didn't charge and the battery was really low, so I plugged it into my charger.
--Nothing--
Hooked it up to my computer
--Nothing--
Strange thing is, if I shut it down and leave it off, it detects the charger being plugged in and appears to be charging. Also, my OTG cable seems to be working fine. I hooked up my Xbox 360 wireless adapter and was able to pair and use it with my computer. I've tried wiping and re-flashing, restoring from backup, all results are the same.
Can someone give me some insight?
It seems the battery is really low. Try to use the stock charger since it has higher current to charge
Doesn't matter what charger I'm using. If android is RUNNING, it will not charge not do any USB operations (except OTG) I can't read it on the computer, charge it off the computer, charge it off any USB charger including the stock one, adb to it, fastboot to it. But if I shut it down, it will charge when it's completely turned off.
It's charging same thing happened to me when I turned it on for the first time. After putting it on for some time remove it and after some time it turned on with full charge..
In my case i Don't know why it didn't turned on just after the charging..

Hi all,
I have a Nexus 4 phone for 6 months, and I love it. But yesterday i got something very very annoying. I almost cant charge my phone. I plug my N4 at wall, with original cable and charger, but after something like 30 seconds, it says I have usb connection, and doesnt charge. The temperature is ok, i already tried factory reset, but nothing works. I see that it doesnt charge even if device is shut down. I tried other cables, but the problem persists. I can connect it via USB, and I can access and modify files, but it slow charge, or even discharges.
I am afraid its a cell phone problem, because where I live, I dont have RMA service.
Thank you very much!

In chronological sequence, I posted three images of what happens. It says battery health is good.
If it's not cable fault maybe it's from the wall charger.
Can you try with other wall charger? i.e Samsung, LG, Asus...
If you've installed a custom kernel you could try to enable the FastCharge hack.

I tried a Samsung and a motorola cable, same thing :/
I have rooted phone.
with clock work 6.0.4.7
Installed Android L Preview ROM for Nexus 4
Everything runs fine.
Problem/Error.
While on charge it is showing charging on USB even while connected to the socket it should be Charging normal/ Ac Charger/ charging.
disadvantages: device heating up. Charging slow.
Turning of the phone.
Charging while turned off, starts charging then it reboots into the recovery. after few seconds.
Please need help.
FIXED.
Flashed 4.4.4 Nexus 4 stock rom.
everything working fine.
Rooted and had nothing wrong with the recoveries or anything the Android L rom i flashed had issues. waiting for a fix.
try a different charger or chord, most likely its one of those items fault.

Thanks for the reply bro.
Everything worked just fine before the root and the Rom installation. The charger and the chord works fine on other nexus 4. Used samsung s3 charger chord as well it detects it as "Charging via USB" not "Ac charger" and if i charfe after shutting down phone. It boots into the CMW it self after dew seconds and stays there. Device heating up both ways.
try a different charger. they go bad and often. if its not producing enough voltage, then the phone will see it as usb. itll see anything as usb if it doesnt provide enough volts/watts.

Did a reset from CMW now while turned on it detects as AC charger tho charging took long. Turn off it boots into the CMW recovery it self.
Me too, using the stock charger it will charge as USB; but when using car charger, it will charge as AC... stock ROM + kernel.... try different USB cable also same, I suspect is the charger having some problem...

I've seen this question pop up a while ago but it doesn't appear to have been solved. Someone mentioned that the KTManta kernal might have solved this but I couldn't find that answered anywhere in that thread (here). I am using the USB OTG cable to control an IR Droid USB transmitter in a permanent kiosk installation and I need the pogo connector to supply power so this can run 24/7.
Any help is much appreciated!
UPDATE:
Wooo!!! Just thought I'd give the kernel a shot and see what happens... it works! I have a separate USB voltage meter that confirms, as well as seeing the battery % increase while being used, and my IR Droid is also working.
Just install the above mentioned kernel, plug in the USB Y OTG cable into tablet, external power supply to the male USB end of Y adapter, and external device (mine being the IR Droid device) to female USB end. Plug second power supply (I used the 2.4a (12w) iPad charger) into pogo connector. Win.
Ktoonsez, your next few beers are on me, good sir!!
UPDATE: The latest KTManta kernel (04-06-2014) breaks root (SuperSU) with the stock rom. In my case that is v4.4.4 so I've had to revert to my nandroid backup. The issue has been known for a long while but it seems the dev is prioritizing his kernel on other devices. Obviously this means I'll not be testing any time soon.
Interesting, I've wanted this solution for a long time as I use an USB Ethernet adapter from a room with poor WiFi reception. I'll see if it makes any difference if the OTG USB device is attached to a powered USB hub or not and report back.

Oh man, I wish I knew about it breaking root before installing!! I was wondering why it was saying I wasn't rooted... Is there a way to fix root while on this kernel?
I'm having some issues with the tablets now that I didn't have before - the most basic seems that it won't boot (won't even start the Google logo) if I have both OTG device and Pogo connected at same time when the tablet is off. I did solder my own right angle tip onto the OTG Y cable though, so I may have messed something up... I'm going to be doing some more testing over the next couple days and I'll keep this up to date.
"Is there a way to fix root while on this kernel?"
The root issue with KTManta's latest release is specifically with the stock ROM from what I've read in the N10 KTManta thread. So it would seem that installing a non-stock ROM then installing the KTManta kernel would be the only way to get this kernel and root. I'm unwilling to do that for this single feature. There were comments that root was still working on an older KTManta release which if I can remember is from Dec 2013. I've no idea if that release has the charging features you see with the latest release.
If you go the custom ROM route then read the KTManta thread to find out which custom ROM's are working. Don't quote me but I thought the OMNI ROM was one that worked, please confirm that for yourself.
From my experience stock with the XPosed framework is more stable than any custom ROM and I've tried many.

So there were a few other issues that I found out while testing...
If you have USB plugged in, then reboot, the tablet freezes while trying to boot. It doesn't even get to the loading screen.
It seems a bit buggy as to when it wants to work and when it doesn't, and all the while the tablet says that it's charging so it is hard to test, but I was using a USB volt meter to see if the pogo was actually taking power or not.
The next thing I want to test is using a powered USB hub, instead of a Y cable. Has anybody done this successfully? Does it need the modified kernel? Does it ACTUALLY charge, or just say that it is?

I use a powered hub to access an Ethernet adapter while concurrently having the pogo plug attached. The result is that the tablet drains slower as the Ethernet adapter is drawing power from USB Hub rather than the tablet. The tablet does not get charged in anyway despite the false charging icon indicator. This is why your post was so interesting to me until I discovered that root was lost. I can live the charging and OTG limitations but I can't loose root.

I tried this the same way as SupremeTaco described.
My nexus 10 runs the latest Omnirom 4.4.4 with latest KTManta kernel.
I plugged in the OTG Y Cable, which was connected to a charger and a usb SD-card reader. Then I plugged in the Pogo charger and to my surprise, the Nexus 10 charges yay! (I saw the battery percentage increase as I was using device with screen on)
SupremeTaco thank you for this great tip, I have been looking for a solution for a long time. I can now charge my Nexus 10 16GB while using a Meenova reader with 64GB microSD card - which is extremely useful :good: :good:

I'm glad it helped! But be careful as you may have issues booting with the USB plugged in. Let me know if this does happen to you... it may just be the version of the kernel I was using but I gave up and am looking for another solution at this point, since I must leave the USB plugged in 24/7
Pogo works great

Sorry for the slow response,
I did some testing with both KTManta kernel and the stock Omnirom kernel and indeed booting with USB plugged in does not work. The culprit seems to be the OTG Y-Cable and specifically the power supply part. If you disconnect power from the Y cable but leave everything else plugged into the tablet, the tablet will boot. Perhaps you could have a power switch for the Y-cable and switch it off only when booting?
Also, I have discovered that Pogo charging with Y-cable also works on stock Omnirom kernel. So it seems that the kernel does not affect the charging capability with this setup in anyway, so we are not limited to using KTManta. However the booting issue does not seem to be a kernel-related problem.
Edit: I also confirmed charging in this way works with franco kernel r16 (so it will probably work with all other franco kernels and any other custom kernel)
Hello everyone.
So there's been a quite few roms around the last weeks enough updates and all that. I noticed that on all roms(literally all of them cm11,cm12.1,RR,MOTION ROM) I get a wakelock named msm_otg after I fully charge my phone and disconnect my charger. This wakelock disables deep sleep and doesn't let the phone sleep on screen off. Is there anyone that can confirm this and maybe we can try a fix? Only fix at the moment is to reboot the device but I don't see a reason why I should always reboot my phone after I charge it. (my device is gti9301i)

I think i read somewhere this wakelock is related to when you plug you phone to a computer. Do you charge your phone using pc?

@zigbye82 nope I use stock charger :-/
The only solution, as for now, is to restart your phone after being charged.
I would suggest that you try charging using a different cable or charger and see if problem is still there. For me this wakelock is high when i charge with usb but goes away when i disconnect.

Confirm! This wakelock is related to change state in the internal memory and usb state. Change the cable and check your kernel. In Cm11 and Cm12.1 there is no problem. Ive got this wakelock when using my phone like external flash drive. Don't worry
If you keep getting issues, just reboot right after unpluged the device.
Their whose attempt to resolve this in last public Samsung source. Did it work I don't know?
Recommendation goes for kernel makers along with rom maker's to disable the future on kernel side (as it's been done for CM13).
For those who would say that they need USB OTG I would say it never whose handy anyway as thanks to not power compliant USB controller QC traditionally used it requires external power source & cable with a plug for it.
Using any cable or charger won't change this! All do I admit that charging module placed in cellular modem section can be itchy (from jamming l at full charged to celullular network collapse until whole module is automatically restarted & when that fails to happen even causing kernel panic [making phone to restart]) so use quality cable's/charger.
