Hello, I've built a USB Y-Cable myself, I plugged a USB stick in without powering it... So the nexus alone wasn't capable of powering it... I plugged the other site into the wall socket... The nexus crashed somehow and it showed a black screen... I immediately plugged it out and turned the nexus on. Still working and charging also works... Hopefully nothing was damaged. Does anybody know what went wrong?
Was there any kind of resistor preventing from pushing current back into the nexus thru the cable? Because that could've been what happened and if it was , you might want to be careful not to fry it! Why going thru all that trouble instead , If you want to power a HDD you might want to get a USB hub for that. There like 5 bucks on eBay.

No I dont think there was any resistor... It still works, what could be broken? Yeah I've got tons of them at home but lazy me...
OTG cables are supposed to be a bit special. A stick should be no problem to power from the Nexus. Even portable harddrives work. If the otg cable is correct the Nexus usb port should be put in host mode which then feed your stick with power. If it does not power the stick, host mode is probably not active and it probably will not work anyway. The kernel needs to be patched to allow host mode and possibility to charge at the same time. There is a patched kernel for Nexus 7 for Cm10. I have looked for this myself for my Nexus 10 since I want to power a portable harddrive and charge from my car charge.

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 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

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
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.

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)

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 /:

Hi guys,
Is the data cable included with the N10 the same as all other micro usb data cables?
Can I purchase a data cable off ebay and it work the same as oem or do I need a specific kind/brand?
Does anyone have a link to a "good" cable?
Lastly, I just ordered this thing, should I be OK using it?

I don't want to gain charge time as this thing takes forever to charge.
i have many micro-usb charging cables and have yet to find a bad one. I have some from HTC, HP, Samsung and Nokia.
AAAlan
After some research it seems as if the N10 cable is USB 2.0 which explains why it looks different than my wife's Mytouch 4g cable.
Nexus 10 will charge off any usb cable I guess. You might not be able to transfer data using a usb first gen cable, and the charging rates might differ, but you can use any OK looking usb cable.
Of course if the cable is something out of the jurassic era plus chewed off by rats it might not work.

Try charging it from another charger it or a PC. Sounds like your charger is probably faulty.

Yeah you could try a factory reset. Failing that, re-flash the stock ROM. Failing that, RMA it.

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.
I have tried 3 different chargers and my nexus will only charge when the charger is forcibly pushed into the port, which is not possible to do for a long time, what can i do to fix the problem as at the moment my nexus has been rendered useless.
Also if i cannot fix the micro usb port does the new nexus 7 dock need the use of the micro usb port or do the pogo pins charge the device on their own
Thanks in advance
Just get the dock... It's a much better way to charge it IMO.
