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.
Hi,
I bought PowerGen 3.1A Wall Charger, when I use with original Micro USB cable that come with my Samsung Galaxy S4, the charging current is 1.9A, when I use with a generic USB cable, the charging current is only 700mA. (I have a way to test the charging current)
Does anyone know which Micro USB cable that carry fast current, such as 1.9A like original USB Cable that come with S4, or even better, carry up to 3.1A that this Wall charger provides?
Thanks All.

Faster charging is enabled in the kernel, not by a cable bro.
Hi,
you have to look for custom kernel with fast charging support. I am using faux123 with fauxclock app.

Does anyone have a confirmed working car charger for this phone?
My motorola car charger that I used for my GNex and GS3 isn't fully compatible with the G2. I get a message saying "slow charging" when I plug it in.
What do you guys use to achieve full charging speeds?
I realize there's a Q&A forum, but since this is directly related to accessories, I wasn't sure if it was better suited for this forum.
Nobody has a working car charger?
Both of these work for me.

the powerjolt is much more low profile though
That's just a generic list. The G2 requires a hi power charger

The powergen dual port works great. It has two 2.1amp USB ports, one that works with Android, and the other with Apple products (when using a data cable --> detecting USB vs AC charge mode). I have custom USB cables where I shorted the data pins so I always pull at AC charge rates regardless of the port type. In any event, this charger should provide you with the same capability as the OEM wall charger.
I have a 2amp car charger and it works fine, no message about slow charging.
the issue im runnin into is find a usb cable that enables fast charging
i have a dual usb car charger that put out 2amps per usb but cant.find an aftermarket usb to micro that can support more amps (fast chargin)
the oem lg g2 cable works...as well as the nexus 7 cable
i got this cable but doesnt charge more than 1amp

To short the data pins, I actually cut a USB cable, stripped back the insulator, re-soldered the +5V and ground wires, soldered together the data pins on the microUSB side of the cable, and stagger cut the data wires on the other side. Prior to the re-soldering, I slipped some shrink tubing on one end of the cable to re-insulate everything. Not for the faint of heart.
Background for those that don't know... Typically, Android phones look for little to no resistance on the data pins to detect a high current charger. Any other load triggers USB mode since most PC's are only designed to supply 500mA via USB. I assume this is a safety issue to prevent overdrawing a PC's port. Apple operates differently. They look for some nominal resistance as USB and switch to fast charge under open or some higher resistance. Most chargers >500mA are designed for the iPhone market unless they explicitly state other compatibility. Therefore, the data pins are floating. Any charger can be used at its max rating if you trick the Android phone with the homemade cable described above. Of course, then it becomes a power-only cable, useless for data. Clearly, OEM chargers for Android phones short the data pins internally so your OEM cable can be used with a wall charger (fast) or with your PC for data connections and nominal (slow) charging.
So the powergen mentioned above has two 2.1A ports, one labeled NA (non-apple) and A (apple) so you don't need to worry about mix-n-match devices and cables. Any USB cable will fast charge on the appropriate port. With my homemade cable above, my Galaxy Nexus will fast charge on either port.
Fast forward to the G2... Just got it yesterday and while in the car, I noticed my homemade cable only permitted SLOW charge on either port. Huh. Kinda a head scratcher. I ran in the house and got the OEM LG cable and both ports worked with FAST charge. So I tried one more thing, I grabbed a regular USB cable and observed the following: the phone went into FAST charge on the apple port and SLOW charge on the non-apple port. I can only assume that LG is detecting fast charge in a different way. The fact that a standard USB cable doesn't work with the data pins shorted at the charger but the OEM cable does makes me think there is something about LG's cable that allows it to pull max power from the charger. FYI, I plugged the OEM LG cable into a 850mA Motorola AC charger and it registered as SLOW charge.

I have pretty much the same thing, had a cable that would only do slow charge, so I stripped the wires back, and on the micro usb side I cut the green and white(data) and twisted them together. Now its fast charge no matter what charger I plug this cable into.... not sure why urs isn't....
My AT&T branded charger doesn't give me the slow charge notification.

Yes, but its not a 2 amp charger. We want a bigger fast charge vehicle charger...
I tried the USB plug in my car (Scion 2012) and two different Belkin cigarette/USB chargers today. The USB and one of the Belkins gave slow charging. The other Belkin did not -- worked fine. They were supposed to be identical, but I had suspected one was a fake. Guess I was right.
I just use the usb cable that came with their phone and plug it into my auto usb or the car's 110 outlet.

I'm not sure how to take advantage of the full 2A charge. Im using a recommended 2.1A/1A car charger for my nexus 7 that i installed in my dash.
My setup consists of a USB OTG right angle cable, a usb 2.0 male to male standard cable, and the 2.1A port.
Im also using USB rom
Under USB settings, it says USB fast charging, but my tablet is DISCHARGING quite quickly.
Is there a fault in my setup? much appreciated. Thanks:good:
So upon opening the phone and checking out its little handbook thing, it says they highly recommend using only ZTE cables and adapters to charge their ZTE Axon 7. I am curious how safe it is to plug this phone into my Tronsmart or Anker cables, has anyone had any issues with using anything besides the tiny USB Type C cable?
Also, what about using a long USB cable with the USB micro to USB Type-C adapter, does that work fine?
