Hello all.
I have had Nexus 4 for 2 weeks now. Absolutely love the device. Doesn't really have any problem with it. Last night, my phone didn't charge when I plug it in the wall charger (LG charger with Kindle USB cable). So I thought I forgot to charge it. I plug it in the wall charger at work, a HTC charger/USB cable. It is still not charging.
But if I plug it into my laptop, it chargers and I can transfer files between the phone and laptop.
I haven't even rooted the phone yet. Locked bootloader. Stock everything and the latest update.
Noticed that there is something similar going on with S3. So this is not a Samsung problem. It's an Android problem.
Any help is appreciated.
EDIT: Nevermind.
I think it's the charger's fault. Glad it's not our phone though.
Have you tried using the wall adapter and cable that actually came with your Nexus 4?

the wall adapter was from LG. I don't think the USB cable is faulty since I can connect to Laptop ok.

You should try the wall adapter and cable that came with your phone just to be certain the phone is faulty. Different adapters have different current outputs and different cables are better Suited to handle larger or smaller outputs. The kindle cable you speak of I know for sure is not designed to consistantly output at higher levels. Also, Older Samsung wall adapters like the one that comes with the Epic never had enough current output to charge my HTC phones anywhere near as quickly as my genuine HTC wall adapters.

Is it USB3?
Where can I buy one to recharge my n7 in 2h30min?like original cable.
Mine is dead....

Its a normal micro USB cable, USB 2. A cable is a cable, most of them should work (all of them actually, a standard is a standard...)

+1 Look around, the Asus charger is rated at 2A and that's the "trick" for fast charging, modules/generic by others are often rated at .5A to .7A like those in (non-smart) phone days from Motorola & LG's or even Samsung's. The standard/universal micro-usb cable from HTC's are great (got like half of a dozen of them around) and their charger is rated at 1A and it will charge the N7 at a slower pace, but it's fine for overnight and so far so good, no problems (knock on woods - )
Oh, yeah, BTW - those generic ones from eBay or sold on Amazon as a bundle are just as good in that, they work too - dah dah. From what I know, practically all of these cables - branded or otherwise, are made in China ...
Do you have a cell phone? Most likely it uses the same cable. I charge my S2 and N7 with the same charger/cable combo. You can find one at almost any cell phone store.
Every USB Cable will fit as long as its a micro USB. loads of places sell them but eBay would be your best bet, PC World is a rip off

Cheap thin cables have significant resistance, and do not deliver 5 volts at one amp. If the drop is severe, the Nexus will go into slow charge mode, like charging from a PC.

I was also under the impression that the supplied N7 cable is a USB3 cable and the charger output is 5V @ 2Amps. If I use the original charger, I can substitute my Bionic cable and it seems to charge just as well. The supplied cable is quite thin compared to the typical usb2 cable.

USB3 is an entirely different kind of connector and has minimal PC support as of yet and is not backwards compatible. USB2 is almost universally supported by virtually every PC manufacturer.

AFAIK USB3 isn't entirely different from USB2, and actually backwards compatible. I have USB3 HDD Drive and can easily connect it to my old laptop or USB2 port on my PC. same with my USB3 card reader, i can use it on my USB2 with no problem. Downside just reduced speed, USB3 to USB2 will only reached max speed of USB2 capable of.
I have two USB3 ports on my desktop and they look nothing like the standard USB2 ports. I also have a USB3 hard drive and its cable will not fit anything but the USB3 ports on my desktop.
According to Tom's, there are significant differences even if you can plug one into the other.

Max speed will always reduced if you plug USB3 device to USB2 ports.

The first caption in the article you list says "USB 3.0 Type A Connector. Yes, it’s backward compatible with USB 2.0." which contradicts your statement about your hard drive and cable. You may be thinking about the micro USB Type B connector for usb 3, which is a different thing entirely.

I am only going off what's on MY motherboard as far as connectors and they are visually different from the USB2 connectors. My USB3 HDD enclosure came with its own cable and the end that plugs into the USB3 ports on my MB does not fit the USB2 ports. Apparently, it shouldn't be that way, but it is.:silly:

I'm very curious to see what the connectors look like on your MoBo as I am not aware of any that have a non standard USB connector of any kind, as such a thing should not exist.
Would you be able to take a photo, for curiosity's sake?

I'm currently in L.A. until 2/26, so not until then. I was somewhat surprised myself because I assumed they would be backward compatible, but there is definitely something different on the USB3 end of the cable and on my motherboard that prevented me from plugging it into any of the USB2 ports.

It's interesting how my old microusb cable slow charges the phone.
Are there different microusb cables with different amp charge?

I saw someone mention that there's a pin removed and that's the detection method but I just don't buy it. I am using a standard, off-the-shelf MicroUSB cable plugged into my Nexus7 charger (2a) and it doesn't complain about slow charging at all. I'm not sure if this is anecdotal or not, but I have confirmed that a stock Micro cable + 2a charger will do fast charge.
When I connect my G2 to my PC, I get the message about how it will benefit from a 3.0 USB port. As far as I can tell the USB adapter it comes with isn't a 3.0 compatible cord. I was thinking about ordering one from Amazon. What do you guys think?
*UPDATE*
Looking at the connection, a 3.0 micro cable will not connect to this phone. Wonder why I get that message. I'm guessing that this is a misnomer my PC is throwing up.
My guess is this is just a generic warning Windows 7 likes to put out for anything it thinks might be usb 3.0 compatible

No other phone or tablet I have ever used has said this, even some new ones using Snapdraon 600 chipsets. My guess is that the Snapdragon 800 in our phones does in fact feature a USB 3.0 controller for it, but we probably just have the port for a 2.0 cable which is standard.
EDIT: found this:
LG’s G2 is equipped with the Snapdragon 800, a 2.26GHz quad-core Krait CPU paired with the Adreno 330 GPU. It supports USB 3.0, up to 4K video playback and capture, and supports Quick Charge 2.0 for up to 75% faster charging times.

I am seeing the same error. Based on the color of the USB on the supplied cable, it is not a 3.0 cable. However, the device is 3.0.
I am having issues finding a USB 3 to USB micro (not micro B) cable. It would be nice to have when the time comes to start moving ROMs from the desktop to the device :laugh:

Did you see the pic I posted above? A 3.0 micro usb cable has extra pins and it's a different shape. The chipset might have 3.0 architecture, but the port is only 2.0. Maybe on a future model this might com about, but not on this phone.

Yes, I did, and the emoticons in my post were not intentional, as they are supposed to be the letter B.
The cable you posted is not what we are looking for. We need to determine if there is such a cable as a USB 3 to USB micro. This is different than the pictured cable, which is UB 3.0 to USB Micro B.
I do not have my stock cable handy, so I cannot remember if it is USB 3 at all. Is the plastic blue inside the USB side?

I think you're a little confused. You refer to "USB Micro" and "USB Micro B" as if they are different connectors. They are not. Yes, people commonly refer to it as a micro USB connector, but only because they don't know or drop the "B". The LG G2 has a USB 2.0 micro B connector on it. It does not have a USB 3.0 micro B connector on it. The cable pictured earlier in the thread is the proper USB 3.0 A to Micro B cable. Obviously, it won't fit in the LG G2, because the LG G2 does not have a USB 3.0 micro B connector. This does make it very strange that a computer would pop up a message saying that the device would work better on a USB 3.0 port when it doesn't have the necessary physical connector to support USB 3.0 but, well, sometimes technology does strange things.

What is a micro cable that's not a B? You mean a micro A?
The stock charge cable is not 3.0.
Can't you just check the transfer speeds?
The Lg G2 micro usb is not a Hdmi port, but it still supports it, through a MHL adapter. So maybe it also supports usb 3?
I am wondering if we can disassemble the phone and replace the USB board with a board that has a USB3 port soldered to it. Then of course also cut out the outer case shell to have a bigger hole. Wouldnt look as nice but it sure would be nice getting much faster speeds since both the chipset and storage system are easily capable of so much more.
Also, this is what a USB3 micro-B connector would look like on a phone:
The micro USB port is not MHL incompatible. It uses slimport like the Nexus 4.
Based on the service manual and the physical configuration of the port I believe that this phone has a USB 3.0 port, but we just don't have a cable or adapter yet to access the rear pins. Attached is a sketch I made showing what the port looks like. The service manual on page 468 supports the physical configuration of the port (3 pins on each side of central standard usb 2.0 5pins ). I am hoping the Nexus 5 will have this port and help LG push out the necessary adapter. I hope we can get some official confirmation on this at some point. I would use USB 3.0 for transferring or recording video directly to flash drive. There is also a potential for 4K recording like the Note 3. So big files would be common place while recording a 4K. 4K streaming from a G2 to a ultra HD tv has already been demonstrated at a trade show in August.
So yes, I believe a micro USB 3.0 port could be added, but by no means would it be easy, or look right. Best just hope for an adapter.

The LG G2 definitely does have a USB 3.0 connector, but unfortunately it is a proprietary non-standard connector. See my previous post. I can not find a cable with this strange new connector anywhere.

When they are saying its an A cable or B cable, they are really talking about the what the end connector will be. Think of the A connector as the standard usb connector you connect to your computer or to your wall charger. Then think of the B connector as the tiny usb connector you connect to your cell phone or tablet.
Companies sell A to A usb cables or A to B cables (which is what all cell phones use). A simple wiki search on usb will help clear things up.

You're saying it is USB3 compatible, then is this why the plug feels very tight to fit into the connection port? Sometimes it even makes a bit of a cracking sound, as if its not connecting properly, before finally fitting properly.
Looking into the connector, it does look a bit different from my Razrs connector.

That is probably for the most part because it new, but can't say for sure. My Google Nexus was getting quite loose, and I know it was tight in the beginning. It doesn't have anything to do with the proprietary USB 3.0 connector because if the plug is ever released it will be about twice as long as a standard micro USB 2.0 to reach the extra pins. I still can't figure out anything more about it.
Unfortunately from comparing various tear down of the LG G2 and the FCC teardown pictures of the Nexus 5, the Nexus 5 looks to have a standard micro USB 2.0. Definitely not as wide as a standard USB 3.0 and not as deep as the LG G2 proprietary USB 3.0 connector.

Still, there's something off about the charger on the G2. It doesn't match my Razr one, but the Razr plug fits in the G2. The other way around works, but is very, very tight.
Where did you find the breakdown of the G2? I've been looking but didn't find anything.

It is also driving me nuts to see if 4K video recording will ever be possibly. I would like to record 4K directly to a USB 3.0 thumb drive.

Both cables included with the 6p are too short for my use cases. I've bought a C to USB 2 cable but I'm having trouble finding USB C cables longer than 6ft. Also I've noticed that there are plenty of issues with cables that are advertised as rated as one thing but really another
I like the one+ cables. I know they are not over 6ft but just a suggestion.....I have a USB extention cable....USB A male to USB A female that I keep in our minivan. It allows any charging cable to stretch across the entire vehicle for long trips when kids/passengers battery is low on any device. They are cheap and worth using if you are using a USB A to USB C....if it's C to C then I'm of no help to you lol
Isn't there a issue with the cable in that it's 2a vs 3a? And yeah primarily concerned with c to c to replace the one packaged with the phone

A cable is a cable, but will be rated to carry a certain amount of power with a certain amount of losses. The longer the run, the more the losses.
Longest I've been able to find are 6.6ft. Cable Matters is one that uses metric and so is a little longer than a 6ft cable. PECHAM C32 [2 Pack] 6.6ft USB 3.1 Type C Cable USB-C to USB-C Male Reversible.
