There have been quite a few people that have come into one of the IRC channels for this phone with complaints of very slow charging batteries. There have been a lot of theories regarding the slow charging, but after testing for about a week I think I may have a possible solution.
Many stated that they were using USB ports on their computers or USB hubs, while others stated that they were using the wall adapter's from their old phones. The problem with this is that, although USB 2.0 ports have 5v output (the same as a wall outlet), they only MAX out at 500mA (milliamps) or .5amps. USB 3.0 ports output at 900mA, so this is almost twice as much as 2.0...but still more than half as low as the wall charger. Also, not all wall adapters will handle the same electrical output. They range anywhere from .5amp through 2amps. The one that Samsung bundles with this phone is 2amps.
So, if you are experiencing extremely slow charging while connected via USB to your computer or hub (or even using the wall adapter for your old phone) then you may want to charge your phone via the supplied wall adapter. I realize that its probably inconvenient as most like to connect their phone to their computer while they are at it, but you can't have it both ways. And for anyone that thinks that their USB 2.0 ports are somehow magical and their phone charges more quickly than others through this method, it's not possible as 500mA MAX is the industry standard.
I tested my, and my girlfriend's, phones for the last week, and this is indeed very much the case. Laptops can put out slightly more amperage, but it is negligible.
Charging tests were performed on 2 different laptops and 2 different desktops (one through a hub and one direct to the USB port on the PC itself).
Charging from dead via USB took ~8 hours (one actually took about 12 hours during one of the laptop tests) to fully charge from dead.
Charging from dead with the supplied wall adapter on either phone took ~2-3 hours.
Charging from dead using the wall adapter from the HTC Evo 4G took each phone ~6 hours.
I realize that this will vary in some degrees from user to user, but I think for the most part it will be correct. I also had two friends run similar tests (one used the Evo 4G charger and one used the Evo 3D charger) and their results were very similar.
Most of this is probably common knowledge to many people, but for those that didn't know, I hope this helps.
Umm...the charger included is rated at 1A?

i have no charging issues, what i have found is that the charging light wont go on after low battery warning unless i power off phone and then reboot.
and to stay on topic..
2-3 hours a/c charger
4-6 hours usb or d/c
light use gets me 2 days on battery - stock / no root

Hi,
I have noticed my phone charges much quicker via the USB on my PC. It takes about 2 hours to charge fully, while the wall charger takes 3-5 hours to charge like 40% or something.
The specifications for the wall charger are:
INPUT: 100-240V ~ 50/60Hz 0.2A
OUTPUT: 5.1V=== 850mA
I do'nt know what the specs for my USB port are? Can I check it in the BIOS? I have googled and found it's something around 5V 500mA, so technically my phone would charge slower...
This is how the wall charger looks like (you can unplug the USB-cable and use it on the PC since it's not a standard USB-mini connection).

Well the 500mA is the minimum spec for USB, basically they say its at least 500mA so that manufactures know how much power to expect and can design devices to run at that amount of power or less. That being said, USB can be anything above 499mA, I have seen a laptop put out 2000mA before even. So yes it is quite possible that your computer could put out over the 850mA of your charger. It probably won't say what its capable of delivering in your BIOS, if you really want to know you could try to find the specs for your computer/mobo/usb chipset. All that being said, you could always get a different USB wall adapter if you wanted to charge faster w/o a computer, just because it came with the one you currently use doesn't mean you have to use it (it is just a powered USB port after all).

Thanks, I will have to look into this, since someone else was implying my charger is broken...

Seems like your wall charger is defective, normally It takes about 1.5-2 hours for working wall charger to make the job done.
Standard PC USB port output is 5v==500mA, so it's strange that you can fully charge 1140 mAh battery just in 2 hours.

Interesting to me, though maybe already known:
I could not find my GT10.1 wall charger the other day, so on a whim I tried my Fascinate's wall charger (with GT 10.1 cable). This wall charger seemed to charge the GT 10.1 with no issue.

$0.43 + $3.48 shipping on Amazon - pretty cheap way to get a back-up to stick in my backpack.

As should any USB type charger. My iPhone charger and my Jawbone Icon headset charger worked as well but takes longer to charge due to the lower current rating.
Agree with MisterEdF.
I have the same plug with my Nexus S and my Epic. Both WILL charge but it's slow as hell and there's definitely the Red X letting me know that it's not the 5v2a charger the tab would like to see. Can't see why the Fascinate charger would be any different...
I believe that is a .5a charger and our tabs come with a 2a. The most it really can do is slow the battery drain. It'll take at least 4x the amount of time to charge.

I dunno. Over a ~couple hour period the battery went from 24% to ~50%. Not as fast as the stock charger, but certainly not zero.

It will slow the drain if you are using it but if you simply want to charge it over night it should be fine in a pinch.

And so will the B&N Nook Color charger. Essentially, any one will work but the standard, lower capacity ones might take forever to charge. The Nook Color charger provides ~1.9A @ 5 Vdc in place of the more standard sub-1 Amp chargers.

Do you have to use the white charger that comes with it or can I use my old desire hd black rounded one. I'm just thinkng that the voltage or ampage or whatever it is may be different. Looking to keep a charger in the office you see. Also does it make a difference in terms of battery life and general goodness for the phone if you charge connected to your pc. Much obliged

No you'll be fine with both. Both will state their outputs on them, and both will be 5VDC at 1A. Generally any charger with a micro usb plug on the end will be charging at 5v. Charging current capacities vary. My wife's blackberry charger also works, but only has 600mA output current so charging the phone could take 40% longer. I've been using my desire charger on my onex.
The main reason to keep with HTC chargers, is that the cheap ebay Hong Kong stuff generally have cheap AC/DC converters in them, and are poorly regulated. This can cause a number if problems witha smart phone, such as heating and damaging the battery, and touch screen interference.
Charging froma PC USB output limits the charging to 500mA, so obviously will take twice as long as your HTC wall charger to get a full charge.

I've been using the charger for my HTC Desire with my One X since I got it - simply because it was already plugged in I've had no problems with charging.
Not working with Moto charger

Well, I am in the situation now that somehow the One X will not accept the Motorola Atrix (US) charger (I am in Singapore, but chargers "convert" automatically in my experience). It works fine though when plugged into the PC, but obviously will take a very long time to charge that way.
*edit*
It worked with the Moto charger once the battery charge was up to about 20%. When it was 2%, phone would only accept USB (or, potentially, the original HTC charger which I did not have at that moment).
Hello,
I discovered a weird issue with my phone this morning. I woke up and the battery was sitting at 64% after charging overnight. That seemed a little weird so I tried doing several different things (battery pull, clear the cache, etc...) to see if it would correct the issue. It did not. I just got done draining the phone completely and then plugged it in. In about an hour's time, it charged 2%.
The only thing that I have not tried at this point is a full system restore :crying:
Has anyone else experienced this issue? Do you have any ideas of things for me to try? I am willing to try anything before using a full restore as a last resort.
Thanks,
LBS
EDIT: Well, I dug out an old blackberry wall charger and cable and it immediately fixed the issue. I think its a bad LG charger and USB cable. I guess ill toss them.
I've experienced this. Does your battery stats page look a bit like this?

What charger AND USB cable are you using to charge the device? While I was using the bundled LG charger at the time, I was using an old HTC MicroUSB cable I had from a previous device when I encountered this problem. When I used the bundled LG MicroUSB cable instead, the device charged normally.

I've been using a 3rd party 6 foot long USB cable with a third party rapid charger. Last night my wife needed to borrow a USB charger, so I gave her mine and used the LG provided charger and cable for the first time last night. I hadn't really thought about it. Maybe its a bad charger?

Could possibly be that. I think the G3 might be a little picky with chargers and such you use with it, I'm not too sure as I've pretty much used the G3 wireless charging dock to charge my G3 (and that is very picky with what you use with it, if it's not at least 1.8A then say hello to constant beeps and errors, my old 2.1A Nexus 7 charger seems to power the dock fine.)
Changd the usb cable
Desktop chargers have become of my favorite tech accessories to use this year. It wasn’t until recently this year that I have become accustomed to using a desktop charger for juicing up my devices. These days there are so many gadgets to be charged up by via USB connections. That’s where a desktop charger comes in handy! CHOETECH has a 50 watt 6-port rapid USB charger to help you get all your devices all charged up.
Specs:
Input: AC100-240V
Total Maximum Output: 5V/10A
Charging Port Output: 5V/10A(max)
Quantities of the charging port: 6-ports
Dimension: 88.4*29*71.5mm/ 3.4*1*2.8in
Weight: 158g
After testing and using this desktop charger as a daily driver charging unit, I was please with the results. The cool thing about this particular charger is that it is a smart charger, which means that it can detect the type of charge (voltage/power) that goes into the device(s) plugged up. This helps prevent overheating and overcharging that could potentially damage your devices. Not too mention this CHOETECH charger is fast! The quick smart charge is definitely the selling point for this charger.
Having 6 ports is very convenient. Personally, I have about at 3 devices that need a daily charge; my phone, bluetooth headset, and home wireless phone). With that said, in my house my wife also charges her phone, we plug up the iPad and the PS4 controller needs charged as well. Needless to say, there are many devices in my home that gets plugged up daily or every other day.
I like to have two desktop chargers setup at my desk and entertainment center. The desk has my PS4, phones, tablet, bluetooth keyboard, and other devices here and there that I use a desktop charger with. On my entertainment center there is a media device, phones and tablets get charged up. Both in my opinion make great places to install the desktop charger.
The build quality is rather nice compared to other companies chargers I have used. It has a matte finish and is compact in size. There is a small orange LED light to ensure that the charger is working and plugged into a power source. The cable is long enough to use on top of a 4 foot high entertainment center. The only thing I would change about this build is the bottom needs to have some rubber stoppers to help it stay in place and not slide around. Other than that, this thing works great and I would definitely recommend checking it out.
