Hi guys,
it's been a year I have the LG G3 but since one-two months, it shows the USB like charging message "Slow charging..." when I plug it to the wall and in fact it is slow charging because I tried a new charger that shows me 35 minutes remaining at some point but mine showed 1 hour 35 minutes.
I did some tests and the problem seems from the cable, like I tried using the cable with a Nexus 5 and it showed "Charging over USB" instead of "Charging on AC" with my new bought cable. However, it was the original one that came with my G3 and it used to work perfectly.
So is there any way to fix this cable? Is it normal that a cable becomes unusable after a year? (knowing I usually take care of it well..)
I tried searching google and checking another thread here but I didn't find any useful info on how to fix a previously working cable.
Thanks.
Just get a different cable. The lg charger itself should be a 1.8 amp. I'm personally using a 2amp with the original cord, It would tell me slow charging but with the another cord it tells me fast charging as well. Cables do go bad.

so the option to not charge it is not ticked under power settings, and its set to charge via usb from advanced config and still no dice.
tried different usb ports and nothing
the led is orange, says its charging in power options
any thoughts?
Try a diffrent usb cable, some cables do not provide enough power to charge the phone. (guessing maybe they are old 1.1 cabels). But I know I have a few cables around that dont charge my phone and they also will not work with my portable external usb hard drive because they wont provide enough power for it. But they work just fine with my digital camera.
I´ve read somewhere that disabling USB charging is better for the battery life, so I have it disabled.
You've tried different USB ports, but were they on the different computers?
so i've tried different cables, different ports and 2 different PC's and 2 different laptops.
I know its not the cable i'm currently using because i plugged it into one of those A/C to USB adapters and charged fine.
I'm starting to think its my batter,
If you have tbattery installed, do u get values for all the boxes?
All mine except 3 or 4 are 0 :/
Well, you are not the only one having this problem. Mine is brand new. I started setting it up last night and had it hooked to the computer via usb. I installed a few .cabs such as google maps, myphone, and a few tweaks such as tether, disable sent notification, enable all camera modes, and manila start menu unlocker. While it was connected it said it was charging. When I went to bed I turned it off and connected it to another usb cable on another computer which is an a/c hub. I went to turn it on this morning and thought it was strange it was not fully charged. I continued to set it up a bit and take it for a spin. After a while I turned it off again and hooked it to the usb a/c charger again. I just tried turning it on and nothing was happening. I connected it to the usb again and it finally turned on, but I checked the battery level and it was at 0% and turned off. I have it connected to the a/c charger and giving it a little bit to see what will happen. One thing that seems strange is that the battery discharged more while it was off and attached to the usb a/c hub during the afternoon causing it to refuse to turn on at all. Any thoughts?

I think the odds are pretty good it's your battery. The orange light means power is going through the charging circuit, so you obviously have your settings correct.
I'm guessing you're in Austin or near? If you want to try popping my battery in it for a few minutes and see if it charges fine then, PM me and we can set something up.
the same thing is happening with mine. Sometimes it will charge, sometimes it wont. weird thing is that it only started doing this a few days ago... i know nothing has changed ROM wise, so only things i can think now is maybe the actual USB connector on the phone or the battery, but since I am getting a charge via wall chargers im not sure what to think lol
Just an update.
If i have the USB cable plugged in (and car charger to which doesn't charge as well ) after 15 min or so a warning appears saying that the current is too low to charge the device. Either closed unused apps or switch to a/c power.
I've ordered a 1800mah Mugen Power Battery. Gonna see if it resolves the issue, if it does then i'm gonna call at&t and see if they'll swap my battery for me.
I have found as have others here after reading some posts that if the phone is almost dead or battery is very low then it will not charge via the USB anymore. The orange light goes on and it says that its charging but the charging circuit seems to be protecting the phone and not letting the battery charge.
The only solution I have found, and it has only happened twice so far is to plug it into a wall charger and fully charge the battery. It will then charge via USB again and all is good. I normally only charge my phone with usb while connected to Activesync but once in a while you seem to need to top it up with a wall charger.
It is also highly recomended not to run Lithium Ion batteries right out.
How do you know it is not charging?
There is a difference in the wiring from a wall charger and a USB charger. There is a signal line in the wall charger telling it to charge at near 1000ma. In the USB cable that line tells it to limit the charge current to 500ma. That is the limit for current that you should pull from a USB port. If you are using the unit heavily, you may actually need more then the 500ma., those running the battery down possibly.
If the unit is idle, it will still take much longer to charger from USB then off of a wall charger.

If you are asking me, I know it was not charging because I also had the "not enough power to charge message" and the phone went from about 15% when I plugged it in to stone cold dead by the morning. The whole time it was pluged into a computer I have used repeatedly to charge it with. I then put it on a AC charger and it went to full charger in about an hour and a half or so.
When I plug in my power adapter to charge the tablet more often now I get the Slow Charging notification that says battery is charging slowly due to low electric current of TA/USB connection. Any one else seeing this? I am using the stock charger supplied with the tablet. I have tried this on several AC outlets in several different locations. It does not seen to affect the ability to charge the tablet it just charges it a little slower.

Thanks for the reply. I am starting to think my power adapter is not putting out the correct current it should be. I will try using a different 2A charger and see how it goes.

You might also try a different cord!
You may try to install "battery monitor widget", it will tell you charging in USB mode or AC mode.
I also find the stock LG charger slow charging, the widget shows I'm only charging at around 1100mA max. While the charger itself label said Output 1.8A max. I can't reach this level yet.
If I charge with a stock nexus 7 charger (which is 2A rated), it'll get worse...just reach around 800mA max.
I'm still not sure what's wrong with the charger or the tablet itself...
I can say that the cable that came with the gpad does charge faster than a thinner cable I had. Both were tested plugged into the stock LG charger.
Sent from my LG-V500 using XDA Premium HD app
When I pulled my g pad out of the box and saw the stock charger was below 2A I put it back in the box. I charge my tablet with the 2A charger that my note 2 uses.
I've seen this problem intermittently with the stock LG charger and today it seems to have become a permanent fault. Swapping to my Note 3 charger things are back to normal once more. Swapping back and forth repeatedly the LG charger triggers the warning and the Note charger is fine. It looks like the LG charger is a bit rubbish. I'll press for a warranty replacement.
I have noticed mine recharges really slowly as well. Using the stock charger, and the battery app previously mentioned, it gives me about 1.1A from the stock charger. Using my Vita charger rated at 1.5A I get about 1.4 into the G Pad. It seems their charger just stinks.
I sent them a support query to see if they will replace it without hassle, if they want me to send it back I'll just buy something else instead.
Edit: Heard back from LG, they want me to send the whole thing back to them or return it to Newegg. Not sure why they won't just ship me a replacement charger, it would be much cheaper for them in the long run.

Further investigation revealed the original cable to be at fault, as it would not make a data connection with either of my laptops. Another cable from my old Galaxy Note worked perfectly. Even so there is still a question mark about the charger as well. Today I spoke to an LG support rep who promised to send a new charger and cable. They should arrive within five working days. I had read of mixed opinions on LG's support, but so far it all seems encouraging.
Hey guys, I'm not getting my N5X to report "Charging Quickly" (or Quickly Charging) when I plug it in with my OEM cable and adapter. My friend also has the phone but his OEM cables DO cause the phone to state that it's "Charging Quickly". I tried moving it to different outlets but it's not working. Is anyone else getting this issue?
Additionally, my OnePlus charger/cables do cause it to say "Charging Quickly". Do I need to send this back?
Logic... if it charges right with a different charger, it's not the phone. Try the OnePlus cable with the 5X wall adapter, and the other way around. Or, try a different C-C cable with the 5X adapter. Find out where the problem exists.
How low is the battery? My understanding of the rapid charging is that it charges more quickly the lower the battery is. As it gets close to full it will slow down. Not sure if this affects whether or not the "Charging Rapidly" message is displayed.

I don't think it has to do with battery level, I've had mine at 95% charge and put it on the charger and it's said "charging rapidly". Of course, the "charging rapidly" message isn't exactly a definitive statement about how much current is going in to your battery.
I found this out the hard way the other night. Check that the cable is firmly plugged all the way into the charger (it's a tight connection). My cable wasn't plugged in all the way into the charger, and I couldn't figure out why the status was just "charging" instead of "rapid charging". Once the cable was inserted all the way my "rapid charging" message reappeared.
I actually prefer a slow charge at night, I think it less stress on the battery, no need for quick when I'm down for hours anyway. I actually just got a couple USB-A -> USB-C cables today, will use one on my old bedside generic daily charger, which is not rapid charge.

Well, that'd be hard to do considering the OnePlus cable is USB Type-A to Type-C. But thanks for the effort.
In any case, I tried plugging the Type-C cable "harder" the OEM adapter. Still no luck! Might just have to get a new one!
This is in regarding my several week old HTC10, which I got off ebay. Phone is S-Off and running stock US unlocked firmware.
The phone is not able to negotiate quick charge with the original HTC charger.
If I use my old HTC charger (from the HTC ONE - 5V 1A) or my ipad charger (5V 2A) or my computer USB port (5V 0.5A), the phone will charge, although slowly.
If I attach the HTC 10 charger when phone is 80% or more charged (ie not really using quick charge), the HTC 10 charger will work, and phone shows "charging rapidly".
But if I use the HTC 10 charger when battery is less than 80% (presumably when the phone is asking for higher volts) I get this:
phone shows "charging on AC" for half a sec or so,
then "charging rapidly" for half a sec,
then "discharging".
This repeats every second or so, and the phone barely charges. (Certainly much slower than my 0.5A computer port.)
I suspect that the phone is having problems negotiating a charging voltage with the charger, and cycling on & off repeatedly as it tries.
I guess this is due to either a bad charger, a bad cable, or bad firmware or hardware.
I don't have other USB C cables or Quick charge 3 power brick to experiment with.
Anyone has any idea of which is likely the culprit?
This is not a deal breaker as I plan to use mostly my 1A charger to slow charge in order to preserve battery longevity. But it would be nice to figure out why quick charge is not working.
Thanks all.
Update: Borrowed a Samsung Quick Charge 2.0 adapter, and it worked with my current cable. So I guess the adapter is faulty.
My HTC 10 is about 1 year old, and I've never saw it show the "charging rapidly" message. It always charges normally, but I think that, somehow, the quickcharge thing is not engaging.
To clear my doubts, I've purchased a USB tester (model J7-t), and found out that the phone is charging at 5.08V 1.45A, with factory original charger and cable. With another charger (a regular 2.4A charger) and another cable, it charges at 5,22V 1.45A.
With phone turned off, it charges at 5,10V 0.96A.
I've tried some tips from other threads, like turning the cable over (I assume turning over the USB-C part of the cable), cleaning the USB-C port, restarting the phone, to no avail.
It has no problems connecting to the computer for data transfer, it also charges from the computer USB port.
It's running stock Oreo with stock kernel, rooted, bootloader unlocked and S-ON. As it is, takes over 90 minutes to go from below 20% to 100%.
Is this normal? Anyone knows why it's refusing to quick charge?
__________
EDIT: I suspect that the culprit is the cable itself, a HTC brand cable that came with the phone. It may not be compatible with Quick Charge technology.
I researched a bit about cables, and ordered a couple of these - https://www.aliexpress.com/item/Bli...r-Cable-1m-1-8m-Mobile-Phone/32833209044.html
BlitzWolf USB-A 3.0 to USB-C model BW-TC9. The description page says that it has a 56kΩ resistor, allows data transfers up to 5Gb/s, supports Quick Charge technologies up to 3A, and is sturdy enough to tow cars without breaking. Not that I would ever tow a car with an USB cable ...
Will update this post when the cables arrive and I test them.
__________
EDIT2: Cables have arrived, they're some fine piece of hardware. But the phone still refuses to charge at anything over ~5V and 1.45A. I've also ran another set of tests with a QC3.0 compliant car charger, to no avail - still charges at ~5V and 1.45A. I'm starting to believe that it's some problem with either the phone itself or the ROM/firmware.
I am using xiaomi quick charger and it shows 2870mah charging current at early stages of charging. Charging current was slowly decreased when battery percentage increased. is after 90% it shows below 1000mah and below. I am using ampere app from play store.
