Just got an LG G2. This thing charges slooooow - G2 Q&A, Help & Troubleshooting

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:

Charging from USB?

I keep getting a red X Through my battery when plugged into my laptop to charge, is this normal? I really dont want to plug into the wall to charge
Really hope this doesn't become the case and that it will charge off of any USB charger...in particular like the one in my car that accepts USB Devices.
My friend has a galaxy and has the same issue, idk if its our laptops or what
Okay this has been address. please search but ill answer for you.
This device uses 5v 2a to charge. Hence the wall unit. you computer is 5v 1a or 1.5a (its not enough)
The device will maintain and in some cases when screen off slowly charge when plugged into computer or usb adaptor with the red "x" through it.
you can find a usb adapter cable which has a switch to allow you to charge while connected to a computer. its a data and charge switch. search for it. i think its on ebay.
also you can find on amazon or google shopping wall chargers for the p1000 which work for like 8$

Having this Y-cable will also help with the fact that the USB cable that came with the tablet is so sort. I have a lot of 5V power supplies around but they are all from 50ma to 1a. Can't believe this thing needs to much power to charge, I would think that 1a would be enough just to maintain it when in use.
OK, I got a couple Y/Split cables and I still have red X when plugged into two USB ports, I even tried two ports that are on different controllers... as well as two USB3 ports in my laptop. I even tried my desktop. No luck.
Has anyone gotten this to work?

The red x will show up if you are charging with anything under 2A. If I remember correctly usb 1 puts out 100ma and usb 2 & 3 put out 500ma. Even with a Y adapter you will only get 1A. If the screen is off then you will charge the battery however with the screen on, you are using the same amount of power that the usb is providing. Therefore the x because the battery is not charging.

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 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

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.

Slow charging

Would that help if I get the slow charging icon in notification bar?
Even just posting on here it's discharging not doing anything else
AFAIK, the G2's definition of "slow charging" is any time it isn't getting (close to) a full 2A from the charger. This doesn't mean the phone isn't charging, or that it's going to take an excessive amount of time to charge. Other chargers will work fine. The Snapdragon 800 CPU supports fast charging, but the opposite of that isn't necessarily "slow".
One thing to watch out for is temperature. If the phone/battery is warm, unplug it for a little while, and maybe even turn it off to let it cool down. If it's too warm, it won't charge very well. I found this out the hard way recently when I left it on the original charger overnight, and it still hadn't gotten to 80% by morning.
Right OK thanks but should this really happen with original charger?
original cable too?
Yes original everything
Mine doesn't show slow charging if I use the original cable. I tried another cable with original charger, and it shows slow charging.
It seems like the "slow charging" depends only on the original cable which comes with the G2. I have used another USB cable with the original G2 wall plug and I still receive the indication of slow charging.
Why would LG do that? I could understand that the wall plug has to deliver a certain ampere but it shouldn't depend on the cable... (only apple would do such thing )

You have to remember that the 1.8 amp charger that comes with the phone would be considered a rapid charger for other phones. Which means the cable would have to be able to carry that amperage. The cables will always matter. If the cable is unable to carry the appropriate amount of electricity, a bigger, better cable is needed. It applies throughout electronics, not just to apple.

can anyone confirm a working fast charge cable?

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?

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.

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.

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.

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.

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.

Faster charging using USB TypeA

Hello XDA members,
I would like to ask you if you know a if it is possible to charge my Nexus 6P with the usage of my USB 3.0 OTG Cable and a Male-to-Male classic USB 2.0 Cable ...
At the moment my phone is charging with 0.2A maximum, even with a 2A wall charger ...
The only working charger is my classic Nexus 6P TypeC-TypeC ..
Have a nice day,
George.
I don't know about the first part of your question regarding the OTG cable, but can say that any compliant USB-A cable is limited to 2.4A in the absolute best of conditions. You may find an answer in the Accessories sub-forum where most of the charger and cable discussions are.
When you say your phone is charging at 0.2A using a 2A wall charger, that may be normal. Are you measuring the input current when the battery is completely dead, or closer to full? The phone itself limits the charging current by it's built-in charging profile, so it will only accept full charging from 0-40% then taper off to zero as it approaches being fully charged. See the 6P charging graph. Even with the stock USB-C to USB-C 3A charger, you're only getting less than 0.2A amp during the last 10% of charging. Not only that, but the phone keeps accepting even less current for almost an hour past 100%.
Here's a solution for my problem, first let me you clear the problem/ my case:
I want to use my Nexus 6P as a Android desktop computer.
I already found a way to charge and use multiple USB devices (using a USB hub)
for more info check out General Section I have posted a guide so you can do it too.
I also bought a chromecast because sadly we cannot use HDMI, there is no DisplayPort on our Nexus 6P.
Everything were working perfectly except the fact that my phone was discharging, while actually charging with a 2.0A USB 2.0 wall charger.
Here is the solution:
FInd a way to power up a 16V case fan (those fans that are a inside your desktop case) and make a stand for your phone, COOL YOUR SNAPDRAGON BABY!
Phone is still charging slowly, while the temperature is at 24Celsius stabilised!
Have a nice day,
Have fun with this it is suuuper cool gadget-like creation if you consider doing it too,
George.
