not charging via usb?

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.

Why is my 5x "Charging slowly"?

Just got my 5x today, and it does "rapid charging" when I connect with the charger in the box, but when I connect using other USB cables/plugs (one supports QC 2.0, the other is a regular charger but supports 2.1A charging), I get a message that the device is "Charging slowly."
Are there other certain specs that a cable or charger has to have to take advantage of rapid charging?

Fast charging on USB-C is apparently very picky when it comes to cables. I havent't tried charging from the USB-A cables that I bought, but the reviews for one that I was considering said that the cable limited the charging capability to 500mA. I know little about qcomm's Quick Charging but I do know that it requires feedback from an enabled device before it will allow full power. I wouldn't be surprised if the lack of that feedback from the N5X was limiting current from the charger, but it definitely looks like a quality cable is the first step to success. Notice how thick the factory LG cable is...
Most cables limit current by a significant amount. Even factory ones. That's why the OnePlus One charger was so popular. The wall dongle was nothing special (2.0A) but the cable was thick enough to actually let it output that current. The only difference now is that our phone will actually tell us if it's hooked up to a crappy charger/cable.

Thanks for the reply, I'll have to do some hunting on Amazon for another cable and see what happens.
Appreciate it if anyone else can chime in too.

the Nexus 5X does not support Qualcomm Quick Charge, at all.

Thanks, I know QC is not supported, I was just offering up that I tried one, and that I tried multiple charges that support 2.1A charging.

Interestingly enough, if I use either of the QC certified chargers that I got along with my S6 (which only output 2A) I get rapid charging. Using an Anker QC charger (also 2A) I don't, and using a different charger (can't remember the brand at the moment, but also 2A, but not QC), I also get slow charging.
Hmm...

Original cable charger causing "Slow Charging" message

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.

Problems with Quick Charge

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.

Charging Problem Solved "I Think"

I have been having problems charging my LG V20. When driving and streaming music with Waze I notice that I'm loosing charge capacity, so I have to only use Waze when absolutely necessary, during traffic jams or finding a restaurant or store etc. I keep getting intermittent "Slow Charging" or "Use OEM Charger & Cable" messages. I don't have the OEM charger or cable so I have been purchasing chargers & cables. I bought a 4 port 12V charger with QC 3.0 expecting that to solve my problem. The charger didn't change anything. So I bought a few USB 3.0 cables and just one time I got a "Fast Charging" session. I read a review about a charger like mine and the review rated the charger as poor. So I bought another QC 3.0 charger and went out to the car with the new charger and all my C type cables. Went through all 5 of my 3 ft cables and once again I keep getting intermittent "Slow Charging" or "Use OEM Charger & Cable" messages with the new charger. Bummer. I also have two short 25cm cables that I tried in desperation and Wow, both of these short cables produce consistent "Fast Charging" sessions. With both chargers! The 25cm cables are too short to reach where I mount my phone so I just ordered a 50cm Ugreen USB C Cable 5A Super Charge Cable. I'm hoping a short (less resistance) high quality cable will solve my problem. Any suggestions on another brand 50cm cable I should order as a backup?

You need to check the voltage and amperage of your charger and then see if you can find some specs about your device and look for what voltage and amperage charger it is supposed to have. The power output of the charger is more relevant to charge capacity than the length of the cable being used.

How do you explain multiple charges working in quick charge mode only with the short cables I have and not with any of the other cables, other than a problem with the cables?

Did you do any investigating to determine what voltage and amperage charger is required by your specific device? Did you compare that to the chargers that you have in order to verify whether the chargers you have are correctly rated for your device? That is a more important detail than you realize.
Yeah, I know what you're probably thinking, "I've never had a problem using a different charger to charge other devices that I have used/owned, how can it be an issue now?"
The answer to that is, not all devices are equal.
Maybe the charger is rated lower than is required by the device and when used with the longer, higher resistance cords, it can't provide enough power, but when using the short cord it's lower resistance might be enough to make up the difference. I've had this issue on a Kindle tablet, the charger for my phone would not charge the device quickly enough unless the device was turned off, it would even give the "may not charge" message when I would plug it in, but when I bought the proper charger for it, VIOLA!!, it charged correctly. Well what do you know, the correct charger and cord actually charges it correctly, imagine that, who would have ever thought that using the correct hardware would get the correct results. I'm being sarcastic, but you get my point.
It has more to do with how much the charger itself can provide than it does the length of the cord.
For example, if you had the original charger and the original cord, it would provide the correct amount of charge, but if you were to use a 10ft cord with the stock charger instead of the 3-6 foot that comes with the device, you would see a reduction in how much power it supplies, even more so if the charger is plugged into a drop cord/extension cord at the same time. I've had this exact issue on a couple of devices.
Another example is if you have a charger that is rated below what the device requires and you used the 3-6 ft stock cord, it could decrease the amount of power supplied by the charger block because the charger can't supply enough power to overcome the resistance of the stock cord, but when using the shorter, lower resistance cord with the lower rated charger, the cord's resistance could be low enough that it allows enough power to be supplied.
I'm not saying that it is 100% the issue that you are having, I'm saying that it is something to look into because it is more likely to be your issue because it is common for devices to charge faster, slower or not at all when using a charger that has a different rating than required by the device. Other possibilities are a damaged USB port on the device or the software has become corrupted, you would probably need to flash the stock firmware to fix the corrupted software.
