My N7 shows charging when connected with wall charger but actually its its not charging because battery is draining as it does with out charging.
following are my findings
its happening with both wall charger and PC usb port
wall charger is fine because its changing other devices
USB cable is correct because its working with other device and i can transfer files to N7 when connected to PC
i charge my device by using pogo pins 1and4 with wall charger. i test the connectivity between pogo power pins(1 and 4) with micro usb power pins.it seems that -ve pogo pic connect with -ve micro usb pin internally but positive pin pogo pin shows no connectivity with usb jack +power pin.so it seems that +ve power pin of micro USB jack is defective. Please help me how to fix that.
I'm currently in Karachi Pakistan and N7 was bought from USA from Google play store on September 1st. Please advise should i send it back to USA again to claim warranty or try to fix it buy opening it and replacing port because apparently +ve terminal of port is not working.

I can't locate a usb bob to test ultra-tiny pins on mini? usb so it's hard to triage this issue.
I bought sync/charge and charge cables from BoxWave...they work perfectly and allow me to charge my 8525, S9, 820 and Holux GPS from a battery pack, wall xformer, car charger usb, etc.
I then bought charge cables from JAVOedge.com and they don't work...they do charge my friend's 8525 though.
The JAVOedge cable won't charge my 8525 but will charge my Holux GPS.
Both charging cables are 2-wire and charge/sync cable appears to be 3-wire.
Although JAVOedge doesn't charge my 8525 when it is powered up...noticing another forum thread I powered 8525 down and now it DOES seem to be charging...at least orange light is on.
I recently bought Targus ultra-slim hub, VEC414S and Tumi Universal Slim PS....yet can't get a lockdown on exact usb charge-only cable reqts.
Why can I connect ANY device via USB directly to computer and it always charges with vanilla usb....yet same usb connected to powered standalone usb hub or charger/battery no workee. Is this due to 1A from computer usb and only 500ma from hub?
Any ideas? I'm confused without approp. BOB to check pins with multimeter.

So this may be a silly question, but I've just received the T-Mobile MDA (HTC Wizard) second-hand and without a charger.
The Mini USB port on the bottom allows ActiveSync and charging from my notebook's USB port, but when I try to charge using an AC-to-USB adapter it doesn't work... I've tried two different Motorola phone chargers and a generic one that came with my Jawbone that has a USB female connector on the adapter and you supply your own USB cable. I've used the same cable I was using when attaching to the PC, but no luck.
Interestingly enough, I did get it to charge with the same USB cable once at an airport by plugging it into the Southwest Airlines chairs with the USB power plugs...
So does anyone know? Does this phone require a special sort of charger?
you need a charger that is rated 1.0Amps.
usb is normally 500mAmps, not enough to charge your phone.
I setup a self-powered USB2.0 hub which has a 2.5AMP power adapter. I used a dual male (split) to single female USB cable and plugged the TAB USB cable into that.
This same dual cable & hub works fine to power an external USB hard-drive which won't work with just a single cable for power. I would think with 2+ AMPS it should charge the TAB "normally" (with no "x" on the battery indicator) but it does not, the "x" remains. All other devices have been removed from the hub.
Anyone else been able to get a normal charge off a PC or USB hub with a split cable? It's such a pain to have to put the TAB on the wall charger then switch it back to the PC.
when the screen is off the device charges, despite what the battery display says.

Correction, it trickle charges. Very slowly.

I understand that but I was under the obviously incorrect impression that if you used a double male USB to single female USB cable you would get a normal charge since there is more power available. Is the charge rate dependent on the TAB seeing power on a specific pin of the cable telling it that a charger is connected and not a cable to the PC? I'm connected to a self-powered hub with a big 2.5amp power supply and nothing else connected to it.

If your connect both your pogo cable and your mico usb cable to your pc they won't charge at the same time. Drivers at the kernel level detect that both are connected to the tablet and only let one charge to prevent power draw overload. In this case it would charge from the pogo charger as it can recognize that the pogo charger is delivering a safe amount of power while simultaneously cutting down on charging time. You can however connect your pogo charger and have the tablet charge while the micro usb cable is connected to transfer files to and from your tablet, use adb etc. Let me know if you still have questions.

I would double check that comment. I have a pogo plug and OTG cable with Ethernet adapter or SD card reader attached. The icon that indicates the device is charging shows BUT it is not actually charging. I confirmed this under both Android 4.3.x and 4.2.2

Very interesting, the point I mentioned above is as least theoretically what is supposed to happen when plugging on both charging sources. Just to clarify your device doesn't charge at all when you have the pgoo plug and OTG cable with Ethernet adapter or SD card reader attached?

In theory yes but Google didn't include it in the Android rom. A developer for the old Nexus 7 did add the capability but never for the Nexus 10. I doubt very much that the next version of the Nexus 10 will include a pogo plug connection.
Hi guys, so I recently installed a Nexus 7 into my car however i have a question regarding the charging as my car is sat there all week not being used. Obviously I've got a OTG cable, would it be possible to charge the tablet from powerbank using male to male USB cable, as the micro USB is plugged into the loom. My plan is to let it charge when using the vehicle then if needed plug the powerbank in once a month to bring back up to 100%, as I cant find a male micro USB into 2 Female micro USB's Please help
