Used some other long ones, drainage > recharge.
My Stock and short one no problem.
Tried a long logitech one, no problem now.
My N7 was recently not charging. I was using the original cable and original adapter (and tried all possible combinations of some others I had available). I was worried that recently flashing a kernel caused some sort of issue (it had charged since flashing the kernel, so I wasn't too worried). I removed the back cover, unplugged and replugged the battery cable from the motherboard, and now it charges correctly (in that it actually displays a charging icon on the screen).
Not claiming that this is a panacea, but perhaps it may help others who have the same issue as I.
One of the kernel tweaks available in most kernels is "Enable Fast Charging on USB". Not sure what this actually does but using Battery Monitor Widget notification went from USB plugged to AC plugged. Charging went from 479mA to 875mA. Now I don't think this actually shorts any pins but I think there must be some kind of USB handshaking going on. Maybe Nexus usually detects USB and only lets in 500mA max. (Why, I don't know--must be some USB standard. ) Changing the setting in the kernel apparently changes what the Nexus allows for current. Hmm. It also disables data transfer over the USB while in this setting. Maybe it does short the pins after all. Naahh, couldn't... Could it??
This could possibly have some effect if plugged into an Apple throttled port?
Don't know. If I get one of those chargers with an iPort I'll give it a shot.
