[Q] Charging issues - Verizon LG G3

I just picked up a Verizon LG G3 used...didn't come with the original charger all of my 2amp chargers are INCREDIBLY SLOW, like an hour for %1. I am stock but rooted. If I were using a crappy charger I would understand, but this is so strange. Any suggestions? Perhaps apps that force fast charging? I am new to the rooted scene... Thanks!

Rooting has nothing to do with it.
Either the phone is bad or your cable/charger.

i just got my G3 today and i am seeing a similar issue.
while setting up for about 2 hours, i gained maybe 4%.
turned off, it looks to charge pretty quick, went from 58% to 78% in less than a 1/2 hour.
while the screen is off, it seems to do, ok, not sure i would call it fast. gained 7% in 20 minutes.
i appreciate any thoughts, even if its a "mine isnt slow like that".
i bought it new from swappa (new), and need to figure out if i have an issue.
Thanks

Try to find an original lg charger man the g3 is the pickiest phone I've ever had with chargers(and cable) , everything except the oem charger that I've tried does the slow charge or the not charging thing. I have tried other quality chargers with it as well and they are slow so just try and get an oem one and see if that fixes the issue

those results were with the oem charger included in the box, also similar results while trying my g2 oem charger.

If it's charging slow with the oem cable charger combo it's a possibility it maybe a defect in the charger but again it maybe a hardware issue, get it swapped thru warranty if you can.

Very odd results here...
My Verizon LG G3 charge was quite low last night, so I plugged it into an LG OEM 1.2amp charger with a Samsung cable. It told me that setup was not supported, and it refused to charge At All, so I changed the cable to a gold-plated Monoprice one (excellent cables...I bought 10). No difference, still would not charge at all and it was down under 10%, so I was getting worried.
Then, on a whim, I plugged in an old HTC 1.0amp charger with the Monoprice cable. Fast charge ! Switched in the Samsung cable, still fast charge !
Less amps, not OEM, but fast charge. No charge at all from the LG 1.2amp charger, which was either from my N5 or N7.
All combos worked at A/C charge speeds on my Nexus5.
After the G3 charged for a while and got up well out of the Danger Zone, I plugged it back in to the combo it had previously told me was incompatible and refused to charge from. Now that it was at 50% or so, that same combo charged the G3 without any complaint !
It is beginning to look like there is some flaw in the G3 charging detection circuitry, where it will refuse to charge when very low from a charging combo that it will charge from just fine if it has more battery available.

From what other users have told me the G3 is just very picky when it comes to what charger you use. Mine is the same way. My Sammy charger from my S4 will only charge the G3 slowly.
Something on the Kernel side of things is my guess. It's not something that's terribly wrong with the phone... Just a pain in the ass.

My Samsung charger cable does the slow charge thing on my g3 as well.....yet this dinky cable I had to buy at a rental c as r counter after forgetting my cord on a trip works perfectly. Some cables I bought at 5 below won't work at all....but worked fine on other phones.

I'm using the stock cable but off my Macbook Pro usb 3.0 port. When using the phone it does not charge but actually drains the battery (very slowly). How do I determine if the phone is good to keep?

Mine charges when connected to my MacBook Air.
Also depends on what you are doing on the phone. Get a high quality cable.
