can anyone confirm a working fast charge cable? - G2 Q&A, Help & Troubleshooting

I've found a couple forums on this but no solutions. Can anyone confirm a working fast charge USB cable other than the stock LG 3' long one?
Here is the closest thread I found..

How to know which chargers/cables are compatible?

I want to know this for my car charger

Best buy sells 15watt rapid chargers for car and wall. . There like $30 each but they do a good job. Think the brand name is rocket fish. Just bought 2 a few weeks ago.

Thanks. But chargers are easy to find. What is difficult to find is a USB cable to work. You'll see in the thread I linked on the first post, lots of people are having challenges with finding USB cables to work even if a charger is well above 2 amps. Even using the stock LG charger, no USB cables seem to work except the one that came with the phone, to eliminate the "slow charge" icon and allow around 1500mA of current to be drawn from the charger like it should in a fast charge..
what cable are you using with your new charger? And do you get the slow charging icon?

I think it all boils down to the charging base... I have used the LG, various Htc and Samsung base units with all kinds of mini & micro USB cables without any issues... The base units are rated from 800mA~1.5 and have not had any slow charging issues... I've only experienced the slow charging when connected to the PC or some car chargers...

I used to run a 1.5' usb cable from monoprice and the GPS on my phone would discharge the battery faster than it could be charged. Now the phone charges so much faster.

I have yet to have a problem with any of the generic monoprice cables and wall charges I bought a couple years ago. Only time I get a slow charge notification is using my 1a car charger. My Optimus G and HTC One X chargers and cable work fine as well.

IT IS NOT THE CHARGER!!
It is something in the cable. And good luck finding one. If you use the included USB cable that came with the G2, then it will charge on ANY charger "normally" (fast charge). If you use ANY OTHER cable, it will slow charge.
I don't know what is in the cable or why it makes a difference, but none of my USB cords/chargers work unless I use the INCLUDED USB CABLE.
I had a thread on this already somewhere in the General Area I think. It REALLY sucks because I have TONS of chargers and cables. I have some at work, home office, bedside, 2 in my car, friends cars, etc. I DO use Wireless Charging at night and luckily the phone has a huge battery to last through the day.
There IS a problem here but my thread got ignored like, "I don't see a problem here, just use the included cable". Well yea if I stayed home all the time. My work makes me travel for work so I have to make sure I remove the 1 working cable and carry it with me EVERYWHERE. What a pain in the butt.
Has anyone tried on custom roms to see if perhaps it is something just on the stock software telling it to go Slo-Mo.

My Verizon non usb attachment cable charges fast. My OEM Spectrum cable does as well. My dual one amp car charger charges slow no matter the cable, and my works Motorola and Kyocera cable charges slow no matter the connection. I have a couple Samsung's I need to test. I do not own any generics. I have not tried other combos.

LG Spectrum cable does not work, slow charge, my fault.
However, the straight plug from my new Verizon car charger does work, the USB port also (ONLY with G2 cable so far[tested lg spectrum, Motorola, Samsung, and Kyocera. Older cables]).
Recap: So far ONLY Direct car charger or USB G2 cable has fast charged. Must be chipped or using some different wire combo?

Ok. I can confirm that the cable used for the Nexus 7 (2012) works.
Also, the original cable for the Samsung Skyrocket works.
Works meaning fast charge.
I can't gurantee that this is the cable, but my skyrocket cable does look like the top cable here:
http://www.ebay.com/bhp/samsung-galaxy-s-ii-skyrocket-usb-cable
(Charger looks like it too, but the charget won't fast charge G2)
Edit:
The Skyrocket was really picky about cables/chargers. If it didn't have the correct one, it would wakelock. Maybe there's something with the way it's wired that makes it good for the G2 as well.

It's something to do with pins 2&3 being bridged that enables a cable to support fast charge.
That adapter linked above is supposed to do that.

Yeah, I'm not so sure about that. It may be the software in the phone that is causing the issue. I had to replace my car charger so I picked up a rocketfish 3.0 amp charger. When I originally used it, it was ridiculously fast, literally 30% in about 30 or so minutes.
Now, here's why I don't think it has anything to do with the charger cables. When I got my phone, I kept putting off doing the first update because I wasn't sure if I was going to root this phone. During this time, I got very good charging speeds from my rocketfish 3.0 amp car charger and many of my other rapid chargers. When I decided I wasn't going to root, I went ahead and downloaded the update. Now, unless I'm using the cable that came with the phone, I get the slow charging message with every single charger. I went from 30% in 30 to about 10% in 30 on my car charger.
I may need to pull out my tinfoil hat, but it would be a pretty huge coincidence that all my charging woes began with that update.

Yea something isn't right. I have a GNex, G2, Nexus 7 2012 and 2013. I always check for AC charging in Settings>Status. It will say AC or USB. When I got my Nexus 7s I replaced all of my chargers with fast chargers. For 2 years I've been fast charging. I got 3 different fast USB chargers on my desk, using the existing setup, Everything fast charges except the G2. If I use the included G2 cable, it will fast charge off all of them. The same with ALL of my home/office/car/travel chargers.
I can only get it to fast charge when I use the included USB cable.
Its something magical with that cable.

I haven't even unwrapped the charging base and usb cable that came with my G2, they still remain in the box. I have been using the charging bases from my Nexus 4, L9, Htc One X, Motorola Atrix and a GS3 through out my house and have mixed cables from god only knows where and all of them work. I get no slow charging from any combination. Even using mini usb cables with micro usb adapters attached and they all still work. I've checked all the output voltages and the lowest one is 800mA. Granted my D801 is rooted, but no custom rom as of yet.

Have you gotten an OTA update?
I'm on the Verizon model. The other guy here said he only started having problems after the Verizon OTA.
-sent from my LG G2 using XDA Premium 4

Here's my theory,
There are chips either in the battery, the transformer, or both. When the phone doesn't detect what's required, it gives a slow charge message and reduces the charge speed. I have had previous phones with batteries that had built in chips that I had to buy because the generic batteries without the chips wouldn't work as well. I haven't taken a good look at the battery, and the transformer seems abnormally large, when I get a chance and some spares, I'll probably take them apart.
My tinfoil hat is telling me that LG is trying to rope us into buying first-party accessories, but it may also be a way to regulate battery health. Having a non-removable battery, it may be a move by LG to extend the life of the battery as long as possible.
Also, I just rooted my phone and so far no change. I will try the car charger tomorrow.

No updates from Tmobile as of yet... I can only imagine the frustration though. You would think LG would have made charging the phone, regardless of the model more standard across the board.
Sent from my LG-D801 using xda app-developers app

800mA is a slow charge... You should average 1700mA. Our cable is five pinned (if that matters). I need grab the mA reader app again. Now we know there is kernel check for flux ect. I want to know if the cable is pre chipped as well for check and regulation, isn't too uncommon. I'm beginning to lean more on an over aggressive kernel check though or possibly a combo of kernel and certain chip model check. I just find it odd my straight Verizon car charger and only this cable is working for me. Gonna check car cable pins in the morning. Verizon here, OTA taken. Did not check before.

EVO doesn't respond when plugged in

Hi all, I know that this might be a stupid question but my EVO is non-responsive when plugged into AC power. I basically can't get past the lock screen when plugged in. Which really sucks when I try to shut off my alarm in the morning lol. So I know this must be a setting somewhere but not sure where to look.
I'm running Myn 2.2 rls 4 with an SBC kernel.
Thanks
That use to happen to me with my G1. It stopped doing it when i switched chargers.
It is either the computer, the charge cord, or both. One if my computers doesn't have the drivers for it and one of my cords weren't working. Damn you sexy HTC cord lol.
from my EVO using XDA app.
Yeah try another cord.
This happened to me if I use one of the cheapo after market chargers. The one that does the battery but also has a usb port. If I try to charge off that port, the touchscreen is useless (and it doesn't charge either)
Use the charger that came with the phone. If you still have a problem, off to Sprint.
Ah, so it's not just me then. I am using a cheap aftermarket charger. I'll see if I get the same result with the stock charger. Thanks for the info.
Yup, it's a grounding issue with your current charger.
If you are using an old computer that happens too. If it was working for you before then it must be the charger. If all else fails try a different computer or a ps3. If it charges there it isn't the charger.

Chargers

Any risk in using a different charger than the original samsung one to charge the sgs2?
I use a combination of blackberry charger at work, universal micro usb charger downstairs at home, universal car charger and official charger upstairs.
Any concerns with this?
I've been doing that for ages. I use the droid, SE x10 and iPhone chargers with no issue.
As always YMMV
I am using htc's charger which has a higher rating than samsung charger. No problem at all...

I use a Sony charger to charge my S2 , I have not even removed the Samsung one from the box , As long as you use a branded charger will be fine.
I've tried to use Nokia's 1200 mA charger, It did charge the phone but whenever i connected that charger the phone would slow down terribly. So, whatever you use, try to keep it around Samsung's charger's 700 mA.
Ive found that the standard charger is rubbish! I had my galaxy s 4 month and it broke, my wifes galaxy 3 did same and now i dont even bother with the one out the box, just use the usb cable and the adapter i got with my tab.

At home I use a Lenmar AC-to-USB 1A charger I picked up at Fry's for around $10; in the car I use a 1A Cygnett 12V-to-USB charger, also from Fry's. Both charge the device at least as well as the OEM AC charger; the car charger appears to charge the SGS2 even when I'm running CoPilot Live.
I use the iGO charge anywhere.
It's a tad pricey, but since the GS2 battery life isn't great (my only complaint on the phone), the charger is great for it since it has an internal battery that charges up when you put it in an outlet so you can charge the phone without needing an outlet. Great for in school or walking around, just put it in my bag and press the button and it charges.
I'm using my BlackBerry charger with no issues, I just do it for convenience as the charging time is the same as the standard charger.

I have been using the HTC charger, 200 mA (input), Output 5V --> 1A.
Whenever i connect my phone to charge and try to work on it, i see my screen lag terribly. Haven't tried it with the supplied charger though due to the low voltage that came with it.

200ma is way low, less than half the 500 ma usb standard. Get a new charger. Most of the chargers you are going to see will be 500 ma I would go with double that.
Some (bad?) chargers will disable touchscreen
I have a couple of usb-chargers off ebay and they give some trouble.
When connected, the touchscreen will not work anymore.
This is mentioned in the manual btw.
Guess the SII is a little sensitive.
Yeah, ebay chargers are a crapshoot. Head to walmart or similar and read the power specs, get something that puts out 5v at 1A LPS. This will charge much faster than the often usb based standard 500 mA chargers and the battery will not be harmed at that charging level which is what many stock HTC chargers put out nowdays. Do not get anything less than 500mA, this is the usb standard and works but will be slower to charge. El Cheapo no name chargers on ebay and such may have the spec but may or may not actually put out the juice. You can usually tell this because the phone will have problems like the ones mentioned right here. The stock charger does not put out any special juice, juice is juice. If a charger puts out to spec the phone will work while charging.

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.

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

How to know which chargers/cables are compatible?

I had an HTC Thunderbolt before I got the LG G2, so I had tons of $5 USB micro cables and wall/car chargers sitting around. Well apparently none of those cables are compatible with the G2 and when using the USB cable that came with the G2 with the car chargers I have(the $5 ones from Frys) it only "slow charges".
If I get some cheap cables/chargers from Frys or Amazon, how can I know in advance if it is compatible to allow the standard charging capabilities of the G2?
Thanks,
Craig
I'm getting the G2 in a couple of weeks and I have the generic T-Mobile car charger. I can only hope it works because it's the only one they sell.
eta-On the T-Mobile site it says it's compatible. I guess I will find out soon enough.

How much Current does your car carger supply? Most car chargers are around 0.5A. I think the G2 needs something like 2A in order not not "Slow Charge". The G2 has a fast charging rate.

I'm pretty sure it's a .5A.
BUT what about the cables? it wouldn't even work at all with any other cable besides the one that came with the G2.

It should be 5 volts, 2 amps.
From the AnandTech review:
The G2 can negotiate a 2A charge rate on my downstream charge port controller and charges very fast in that mode. Of course the PM8941 PMIC also includes some new features that Qualcomm has given QuickCharge 2.0 branding.

You should also be safe with chargers rated above 2A, as long as they are 5V. The device will only pull as many amps as it needs.

I had an HTC Thunderbolt before I got the LG G2, so I had tons of $5 USB micro cables and wall/car chargers sitting around. Well apparently none of those cables are compatible with the G2 and when using the USB cable that came with the G2 with the car chargers I have(the $5 ones from Frys) it only "slow charges".
If I get some cheap cables/chargers from Frys or Amazon, how can I know in advance if it is compatible to allow the standard charging capabilities of the G2?
Thanks,
Craig

I think that only applies to Verizon phones. I think they do something to make other chargers not compatible. I have had that issue with different phones throughout time and everytime it was always a Verizon phone. Never have I had that problem with any other carriers phones. I could be wrong but Verizon always does extra things to their phones to be a pain in the ass so its not impossible.
european open has this, too, no org htc or logitech or samsung cable is willing to give its juice through, or better, lg ignores it

I'm getting the G2 in a couple of weeks and I have the generic T-Mobile car charger. I can only hope it works because it's the only one they sell.
eta-On the T-Mobile site it says it's compatible. I guess I will find out soon enough.

It works. I have both models of the T-Mobile car chargers and both work.

Actually, I have the Verizon G2 and can attest that NONE of the gazillion USB cables I've had for various purposes over the years (including my Galaxy S3 and S4) will allow for the Fast Charge feature to work with this phone. They only support the slow charge, which pulls only about .5A of current, even if using a 2A charger... Further, I have several cables that dont allow ANY charge whatsoever. They charge my S3 fine (also Verizon), but when looking at battery monitoring apps, they only show as USB connected, but still are discharging..
I'm actually trying to find where I can buy a USB cable that will support Fast charge as I lost my original one... Any one know?

The BlackBerry q10 charger and the nexus 4 usb cable combo is what I use. They charge the phone just as fast, if not faster,than the stock g2 ones.
The only time I get the slow charge notification is when I use my pc to charge the phone.

Who is your carrier?
The Verizon model detects anything other then a USB 3.0 charger and forces a slow charge (500mah).
Only the Verizon does this. Only the included cable works. Its not the bricks but the CABLE. We are discussing this in detail in another thread.

Have Fast Charge Working
I have the Verizon version of the LG G2. I have found a couple of ways that it will fast charge. I have been able to use a Nexus 7 charger and USB cable. Also found a car charger that will fast charge: GT Max USB car charger that has both a 2A and 1A USB ports. But it will only fast charge with the heavier USB cables. With the lighter cables (USB sync cables) it will slow charge.
Also found an app called CurrentWidget that will show the battery charge rate. This has been very helpful in determining the right combination.
My N7 charger works but only when using the stock cable. In fact, fast charge (ie normal charge) only works with the stock cable. I have not found another cable that fast charges.
My car has the data pins shorted and will fast charge, but actually doesn't charge at all. A 2 hour drive and my battery was actually lower while on the charger. Goofy.

Just got an LG G2. This thing charges slooooow

Bought it used off eBay so not sure if I have OEM parts, but I went from 37% battery to 70% in 4 hours. Slowest charging phone I've ever used.
I did a Google search and found this is a common problem and you need the correct charger and cable. My problem is I can't find any recent information on this and with the stuff I read, there was never a clear answer given.
Has this issue ever been figured out and if so, what charger and cable do I need to get?
The original charger is rated at 1.8A so look for that.
Check your lock screen if it says slow charging.
Ok so I used my moto x USB cable and the g2 turned into the fastest charging phone I've ever had. I didn't know a cable could make a difference. Same wall charger.
So is there a certain type of cable that I need?
It's just the way the pinout is on the cable I believe, if the phone sees it as a standard USB cable such as those used to connect it to a PC, it will go into slow charging mode as to not overdraw the USB port on the computer. The stock charger, and from some other phones, allow the charging at the full ~2A rate.
It isn't a 'problem' at all with the phone. As with any device, technically you should always use the accessories made specifically for it to get the best functionality. Or, at least buy a 3rd party item that is made to the same spec.

As you've discovered, the G2 (and many other USB devices) can request far more than the 500ma provided by traditional computer USB ports. For non-Apple devices (they broke the spec -- thanks Steve!), shorting the D+/D- pins will indicate to the device that it's plugged into a high power port, allowing it to request far more amperage.
There are specific "USB charging cables" that short these pins for you, if you don't feel like rolling your own. I bought this one:

You haven't experienced slow charging until you have a nexus 7

It's your cable. Almost guarantee it. All cables are not created equally.
