As of now, it is on 0% and has been for the past 5 hours. I've also tried other usb cables and a motorola milestone charger/cable and still no luck, please help me.
thanks

I had the same problem. Check the charging unit and make sure the two sections have clicked together.

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.
ASIN: B006BGZJJ4. Item model # 53-000156
Works great on the Nexus 7 as well.

I got a six foot mediabridge cable from Amazon, very sturdy and works fine.

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.

None of my 2.1a chargers work.

Just for the hell of it...... pry the back cover off and make sure the battery is firmly plugged in. This happened to mine and now all is good

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

Nexus 7 Won't Charge

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.

having the same issue and wanted to use the device but right now its dead and useless. any other suggestions then going out and buying a dock for it?

I had the same problem after installing M-Kernel. Removing M-Kernel fixed it for me.

[Q] Nexus 7 Charging Problem

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?
Sent from my HTC One using Tapatalk 4

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)

USB Charging

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.

Nexus 7 SLOW CHARGING

Hi my nexus 7 is charging at a pathetic rate . I left it to charge for 5 hours from 7.00am to 12.00pm and it only charged from 5% to 12% .
It all happened a few days ago . I charged my nexus 7 to 100% (stock rom used for few months alr )and wiped the battery stats . Following that I drained the battery till 0% . After rebooting , the slow charging problem surfaced . I have already did a clean wipe and reinstall of stock 4.1.2 using nexus toolkit , the problem is still there . Help ?

in my country it happened to many people. you should take the nexus to ASUS reparing service and ask them to replace the USB port. it will be ok

Warranty is over . Asus will probably rip me off for it.
Btw just to note charging is substantially faster when connect to pc . It charges from 5% to 31% in 2hrs .

Whether out not your warranty is over depends on where you live. If you're U.S. you are probably out of luck, but you may not be elsewhere - an increasing number of countries now have two years as standard, despite what the card in the box may say.

I have the exact same problem. Started going down hill after install vanir. I thought flashing to stock fixed. it might have for a while. Cant live on stock anyway. Otherwise I don't know what to do with it.

Check your account syncs in settings. I use two different accounts with Google (that real name policy uses a very odd definition of real name,) and if what syncs with each account isn't set just right the poor thing will get stuck awake and trying to sync forever because the awful Google+ will forbid some things without telling the device to stop trying. That absolutely rags the battery.
It's certainly not the only possible cause, but it returns, unbidden, often enough to be worth checking for.

Your situations seem different from mine ...
Anyone has a fix for this ?

I think my nexus 7 has a bad USB port as was suggested in another thread. A closer look it appears to be severed. Android tuner shows a negative flow. Its been fun anyway.
You can maybe PRESERVE IT BY CONNECTING CHARGE CABLE TO ADAPTER??

Another thing I didnt think to try was just use a restricted user profile and charge with that.

I fixed problem with "Wug's Nexus Root Toolkit " flashing 4,4,2 and bootloader 4.23(wich i think was my problem becouse it freezing some times when i was in it).
happy flashing and flash it from bootloader, not developer option.

I had all kinds of charging issues for awhile, turns out the battery cable had become loose. Just pop off the back and check that the battery cable is plugged in all the way and seated firmly. The battery itself was also loose and sliding around in its compartment (probably how the cable became loose in the first place), which I resolved with some electrical tape.:victory:
Hopefully it's not worse than that, good luck.

I created a thread about a similar issue. I have the Asus dock. Charging on there is brilliant. Charging via USB is pathetically slow

So it could be that your charger is not powerful enough ... Tablet need more than phone usually. I know that because I use the same charger for my Nexus and a Samsung SIII and the time it takes to get from 5% (typical ) to 100% is quite different!

I had this slow charging problem on both mine and my wife's N7. Checked, opened and adjusted the battery connector a few times through few weeks but it did not solve the problem. Later I found out it was the usb ribbon connecting to the mirco usb port behind the speaker was loosen even when locked. I cut and stick a small piece of tape on the back of the ribbon, thicking it slighty, relocking it back in place. Solved the charging issue and both devices are charging back on time properly.

I'm having crazy slow charging recently on my Nexus 7 and I'm trying to figure it out myself.. USB or Dock charge the same; about 300-400mA, that's it. USB speeds. Using the stock charger and cable.
I recently went to AOKP so I wonder if it's something there but I can't figure it out.

I've found that different combinations of USB cables and chargers make a big difference. I have a very long micro USB cable I like to use for charging because the couch is far from the outlet, but attaching that to the Nexus 7 or Nexus 5 wall charger yields a slow charge. If I play a game like Magic 2014 while charging that way, the battery goes down as I play. However some of the short USB cables that came with devices produce a fast charge with both the N7 and N5 wall chargers - the battery actually moves up while playing the same game. So I've resorted to using an old-school AC extension cord and plugging the good cable into that so it can reach the couch.

I had this issue for a long time. Tried all the chargers and ROMs I could get my hands on.
Decided that it should be an hardware problem.
I opened up the Nexus 7 and re-soldered all the USB contacts.
I removed the flat cable that goes from the USB PCB Surface mounted connector and cleaned the contacts on it and re-plugged it.
I removed the battery and cleaned the contacts in there with electric cleaning spray.
I re-soldered the battery contacts on the PCB side.
My nexus 7 now goes from 0% to 100% in about 3 hours.

Do you have a video of how to do that? I've bought a new battery thinking that the problema was in my battery. Did not work well, still with the low charging. I don't want to spend more money. So, do you have a toturial of how you did it?
Thanks
