FYI, using a higher amperage charger will be faster, but at the expense of shortening the overall life of the battery cells.
LG spec'd it to 1.8 amps for a reason. Besides, if the phone is an all day device like everyone is claiming, just plug it in when you head hits the pillow, right?

Battery health isn't an issue now that the battery is removable

Someone correct me if I'm wrong but if I remember correctly, all modern phones/tablets won't draw higher amps than they're rated for. For example, if you use a wall adapter that can pump out 2.4A but your phone is only rated for 1.8A, it'll draw 1.8A and charge at its maximum rate. Likewise, if you plug in a device that's rated for 2.4A into a wall adapter that can only pump out 1.8A, it'll only draw the 1.8A and charge slower than it would otherwise.
Using a lower amperage to charge your batteries will prolong their life but like shook187 said, now that the batteries are user-removable, battery longevity has become a non-issue.
How does a higher amperage charger charge faster then?
And I'm willing to bet 10% of removable battery phone owners have ever actually purchased a replacement. It's a theoretical comfort point. I personally have 3 Samsung batteries for my Note 3 and rotate them every few days. I never run out of juice and they aren't worn out when I eventually sell the phone.

Lots of variables involved in determining charge "speed". Again, this is from what I remember (based off of my own Google-fu), but charge speed not only depends on the wall adapter's amperage rating but also the length of the USB cable that you use and its AWG (amongst other things). The phone has a set maximum amperage draw rating and it will not (unless damaged or modified) draw beyond that. If a phone were able to charge faster and faster because you used a wall adapter rated for higher and higher amps, you'd have a lot more phone fires and explosions hitting the news.
My assertion that using a higher amp charger is pointless is, of course, assuming LG or other OEMs don't include wall adapters that are under specced for the phone (e.g. a 1.6A charger for a 1.8A phone) or that the wall adapter, cable, phone, or battery isn't defective . Using a higher amp charger in some cases may very well increase the rate of charge, but there will be a limit to how much it will improve.

Perhaps AlwaysSmile's phone is drawing 1.8amp from the 2.4amp charger, and the reason it's faster is not the higher current but simply that the 2.4 charger is good and the 1.8 faulty. If the 1.8 were good perhaps it would charge as fast as the 2.4.

First time I charged mine it was very slow, I was using a usb extension cable that in have always used with other phones because outlet is too far from my desk.
I removed the usb extension and and bought a extension cord for the outlet itself, problem solved.
Now mine goes from 10% to full charge in under 2 hrs easily.

from 20 % it takes me 5-6 hours to get a full charge.
my lg g2 took as long as wel.l maybe an hour less.
are u charging from pc or wall charger i use pc i hear best results in wall charging
Wall, from PC it takes for ever, its not meant to charge phones from PC.

Guys, again I don't know what the reason here is, but when I used the charger for the G2 it worked perfectly fine, now once I plugged in the G3 it started making fun, so you guys wanna tell me that the cable got damaged from one second to the other? That's odd!
Now that I have a 2.4Amp charger and I thick USB cable that came with it, it just charges in no time! I have no idea how but that's the fact, before you know it the phone is fully charged!

I mean that if others are not having the same issue it's not a design issue. you have something defective with the phone, charger, or cable. If it were just because the included charger "sucks" then everyone would be having the same issue.
If ur not using the stock charger that came with it then that's ur problem right there. The stock charger has a higher charge rate and charges it faster then other chargers

I'd give it a solid week or two for the battery to get broken in. If you're still having trouble I suggest trying another factory charger. (If you can get one.) If you're STILL having trouble maybe contact LG for a new battery or simply swap it out with a new one. With as much crazy tech as LG has put into this phone there are bound to be a few hiccups along the way.

First, the G3 is neither slow nor particularly fast to charge.
AnandTech | The LG G3 Review
"In this test, the LG G3 trails behind both the One (M8) and Galaxy S5 in charge time, although it's quite close to the One (M8). This is strange, especially because the LG G2 has the same battery size. However, this can be explained by the change to charging protocol, as it seems that the G3 doesn't support Qualcomm's Quick Charge technology. Instead, signalling is done over BC 1.2. As we'll see later in the article, this is due to the charger chip used." - from the article
^^^ That means that you probably won't see it charge at a faster rate when it's closer to dead.
Second, the reason a 2.4A charger could theoretically charge faster than 1.8A even though the phone might only pull 1.8A max is efficiency. The LG charger might only be, say, 90% efficient (I'm really just making the numbers up) which means it's not actually putting out 1.8A, more like ~1.62A. If you get a 2.4A charger that's capable of even 80% efficiency (again, making that number up) it'll put out realistic ~1.92A. That would mean that it could give the phone a bit more juice.
That being said, .18-.2A is not going to make the phone charge in half the time some of you are saying that it takes. If you're actively using the phone while charging there is a possibility that your phone won't charge at all depending on what you're doing. If you're plugging in it overnight for 5-6 hours and using the stock LG charger that came with the phone there's no reason it shouldn't be fully charged. Something is defective. If a new charger fixed it, than your charger is most likely defective.

The phone will only take as much amps as lg designed it to. I have an 8 amp charger and my note 3 still only charges at 2a.

I have found that if you tilt the plug slightly towards the bottom it goes in perfectly. Trying to put it in straight I felt like the plug was hitting an obstruction.
