So I just ordered this charger and it charged my phone from 4% to %100 percent in exactly 3 hours!
http://www.amazon.com/gp/product/B0051ZJA64/ref=oh_o00_s00_i00_details
Wow, what a great improvement over stock which takes 6+ hours. This makes me believe, that even though the stock output is rated at 1000ma and this charger's output is only rated 700ma that this charges works correctly!
If you have a 1800mah battery and you charge it at a rate of .7A, it should take it exactly 2.57 hours to charge, (1800/700). With stock it should take less, because 1800/1000 = 1.8 hours, but it takes 6+ hours to fully charge! Something is f'ed up with the stock charger or phone's software...
Yeah. About that. I just got my E4GT yesterday and noticed it does charge extra slow compared to my O.G. Epic.
My wife stayed with hers, maybe I will try charging my phone on hers. I wonder if that would make a difference...

At first my charging was extremely slow but now it'll charge from 2 to 100 in under three hours

I use the Palm charger from my TouchPad. Will go from dead to fully charged in about an hour and a half.
What's you TouchPad charger's output in mah? I think I might have to splice into a spare USB cable and check how much current is actually used by phone when on stock charger...pretty sure it is nowhere close to 1000mah.
2000mah is the output from the TP charger.
According to BatteryMonitorWidget, it estimates avg mA charging at 270mA using the stock charger that came with this particular phone.
I have my original charger from my Evo 4g and have noticed that it charges my phone a lot faster then the stock one that came with the phone. :-( weird

That sounds about right! I'll see if I can test this with my AMP meter tonight and tell you all for sure on stock vs new samsung charger that I've got.

Yeah, at 2000mah it should charge in less than one hour...I would say your actual charge current to be around 1200mah...
i would be careful with these chargers.
i have dealt with a lot of Li-Po's in the past and there was a formula to how fast you should charge them.
i imagine it is the same deal with Li-On.
charging outside such formula could kill the life of your battery or worse.
Seems like i must have gotten lucky as a ton of people are having problems with their phone or chargers.
I just charged my battery from 0 to 100% off the stock charger in 2 and a half hours and i also havent gotten any of the dodgy input problems using the phone while charging.
I went back and took a longer look at the battery history when charging. When starting the charge at 65% it starts off around 828mA, then 540mA, then 360mA, so it looks like (as expected) the phone knows how much current to pull to charge the battery safely and it adjusts based on how full the battery is. Not saying it does this for the charger included with your phone, but that is the behavior for the charger included with this phone.
These are all estimates provided by Battery Monitor Widget because there is no real-time mA current meter in this phone (according to the author)
Ordered one of these. Stock charger takes a lifetime to charge the phone.
My GF got Nexus S 4G and it's stock charger also takes 6+ hours to charge, so there's something wrong with the chargers I guess...
The pins on this charger must me different than the stock charger. Just because the stock charger is rated up to 1Ah doesn't meant the phone or batteries circuitry allows that much output. The resistance and length of the USB pins on the cable are what determines the output of the charger. Simply using a different USB cable with the stock charger will get you faster charge times.
Using a 2Ah charger will get you nowhere, the circuitry doesn't allow that strong of a current. Just a bit of an FYI. Save your money and save your phone, use a different USB cable.
Also, how is the charge time holding up? I doubt you're getting a saturated charge with that charger.

Ive dealt with 1,2, and 3 cell lipos ranging from 150mah to 5000mah, and every one of them either say to be (or ive been told its recommended to do so) charged at 1C. so a 500mah battery should be charged at .5A, 1000mah at 1A, 5000mah at 5A, etc...
my lipo charger displays a bunch of info as the battery charges and it definitely drops the current as the battery gets closer to being fully charged. if its the same with li-on then I would imagine that .18A should be the most you would charge this battery, but Id rather it take a long time because unless things have changed recently, doesnt the slower you charge the battery prolong its life cycle as well as extend how long it lasts each charge? I only charge mine at night when I am sleeping so who cares if it takes longer than an hour. if I get into an emergency situation I have the cig lighter charger and in the worst case I even have one of those crank flashlights I can use to charge the phone in the event my car battery shorted out or something...
Ok, don't be mislead by the title thinking that I'm here to complain about such and such, it's just for your attention.
So, to the topic, since I've owned many a phone, I absolutely love this phone. Everything is top notch, from camera to the current tablet ROM that I'm using. So what's my problem? The battery, I hate it, it does a brilliant job of staying alive, but it literally takes me 3-5 hours of charging to get 90-100%
Many can look pass this, but I can't, I just wish there was a quick way of charging rather than leaving it on through sleep. Probably be changing my phone soon because of this, but to what...
Sounds like u have an issue. Make sure u are using the charger that came with the phone. Others are not strong enough and that could be your problem.
Take a look at the charging slow battery thread
http://forum.xda-developers.com/showthread.php?t=2112811
Look at your charger label it should say something like Output/Sortie: 5.0V with a solid line over a dotted line and then 2.0A. If it is less than 5.0v and 2.0a then it will charge slower. Never use a charger that is higher than 5v or you could damage your Note 2. If your charger amps are say .5a then it is a quarter the rating of the default charger and will be correspondingly slower. Also if the chargers voltage is say 3.5v then it will also be slow to charge.
Im coming from a G2 and both have the same battery capacity and the g3 takes way longer to charge.
I have data and everything turned off. Its been about an hour and its only charged about 38%.
I was using the original wall port to charge but that took way longer, now im currently using a 2amp samsung wallport.
Anybody having issues with charging?
Two hours to fully charge a 3000mAh battery doesn't feel that crazy to me, I dunno.

2 hours 80%
With my experience, using the stock G3 charger works the best it seems.
When I first got my two white G3's last week, I set both of them up to charge next to each other. One was on the stock charger and another was on a normal HTC 1amp block (from my HTC One M7), obviously the stock charger was just a tad over 2x faster.
I then changed out the 1amp block and used my Note 3 2amp block and the Note 3 charger was about 33% slower to charger than the stock charger, quite surprisingly.
Bear in mind, the stock charger says it is rated at 1.8amps.
They were both setup and tracked with % increase in charger over a 2hr period, over two separate days, both with same services, brightness and other comparable settings to track as even as possible use and drain/charge.
Also of note, I saw that the battery for the G3 is a Lithium Poly and not the normal Lithium Ion batteries, was were in my Note 3, that might make a difference, but I am not entirely sure (haven't had a chance to research LioP batteries over LioIon).

That actually isnt so bad.
I came from Nexus 5 with Qi chargers, so I'll be comparing my experience to that.
Is anyone noticing the phone STOPS charging at 100% via the powermat and doesn't trickle charge to keep it close to 100%? I charge my phone overnight and I'm waking up to ~70% charge and charging off (no indicators of charging on phone or powermat). My qi mats all kept trickle charging at 100% so I wouldn't lose battery.
Now the ***** part - I swear the first few weeks with powermat, I was waking up to 100% charge and suddenly it's changed.
So what are other people's experience with this? There was a lot of discussion about qi chargers that behaved differently based on brand. Some did trickle charge, others didn't.
The further I go using an att g3, the more I want to sell it and run to t-mobile.
I'm curious if anyone has been using Qi charging with their TabPro? Anyone's comments would be appreciated.
I used a micro-usb Qi coil receiver between my TabPro 8.4 and the Poetic case for a few weeks without issues.
But then something happened to cause the Qi charging pad to overheat. I ended up having to have the TabPro 8.4 replaced by BestBuy as the TabPro would no longer charge at all, even trying different micro-usb cables and 2.1 amp power adaptors. What was even stranger, was the battery continued to drain even after powering the TabPro off! I'm puzzled as to what was damaged, but the end result was the battery went from 41% charge to 7% charge overnight even though it was powered off (not sleeping, but powered off) and not connected to a charger. When I discovered it was at 7% I removed my account info, but even with the charger plugged in, the battery went down to 3% while working on the TabPro. When I checked on it an hour latter it was dead. If I plugged in the charger, after about 20 seconds it would flash the green battery for about a second, then it would go out. No boot, no charging, even after leaving it charging for 24 hours.
So I'm very reluctant to try to use Qi wireless charging on my replacement tab. I suspect the Qi charging pad failed and overheated. There is a spot about the size of a dime where the plastic partially melted on the charging pad. The Poetic case and the TabPro look fine, and the charging pad still acts like it is working. Very puzzling. Any ideas or cautions?

The only thing I can think of is maybe the Qi charging pad failed to deliver 2.1 Amps to correctly charge it (I don't think they even make 1 Amp coils yet? - though I could be wrong.) , maybe the tab went into charging mode but it was really discharging since not enough current was going in that it needed to charge + keep the tablet running so in the end maybe it destroyed the battery since it went completely flat which is usually a bad thing for l-ion battery's
Usually when android says the battery is at 0% the battery really has about 20% remaining for protection of the battery and preventing it from going completely empty (l-ion can really be drained to 2.5v but android reads 0% around 3.4v or 3.2v if i remember correctly as protection from flat-lining the batt), however if it was under charging mode I'm sure it would override this as it thinks it's plugged in so it's not paying attention to the battery, but really the batt is draining to compensate for the underpowered charger, that would be my guess maybe constantly using the Qi charger the battery circuitry changed the battery status from lv 2 (good) to ~ lv 4 (bad) since it wasn't receiving the current it was supposed to and the circuitry thought something was wrong with the battery cells or the battery just went bad since it was always under a charging / discharging state never reaching 100%.
on a side note
I found this tablet to be very fussy when using other chargers then its official one, I have tried several chargers and they just dont function like the stock one for example
HP Touchpad charger 5.3v - 2.0A - Very high quality charger and even won some awards for beating out other chargers - I found this would sometimes not fully charge the tablet to 100% it would idle around 98% (I have two of these chargers) - Charge current starts around 1800 mAh drops to 200 mAh when battery gets full don't think its enough to top it off. (charges at 5v)
10,000 mAh Power-bank (5v , 2.0A), found out this would not fully charge the tablet either it would get to 80%, upon further inspection the 2A port was only delivering about 1 Amp of current according to my amp reader (voltage drop to 4.98)
Samsung official charger (5.3v 2.0A)- though seems to start at a pretty high 5.60 volts (higher then other chargers) , and charges at about 1870 mAh , always reaches 100% with this charger. (I have two of these chargers since I bought another one as backup - both do the same thing)

That could be the case. Yet, for two weeks, the Qi charging had no problems taking the charge to 100%. It would charge a bit over 15% an hour. The Galaxy Charging Current app reported between 670 and 750ma charging current using Qi charging.
At this point I'll likely never know, but it could be the battery itself simply failed on the tablet. My question is mainly to see if anyone else has used Qi charging, and what their experience is. How can I display the battery status (you referenced lv 2 (good) to ~ lv 4 (bad))? The battery app from the Play Store does display "battery health" but I've only seen it say "Good".
On your side note, I occasionally plug the tablet into the USB port on my computer (measures 5.10V), and it charges at about 10% an hour while sleeping, and has repeatedly charged the battery to 100% when I leave it connected. I have an EnrePlex Jumper Prime 4400mAh that measures 5.18V, and charges at 1.5A. It has charged the battery to 100%, though will run out of juice if the battery is lower than 40% before I use it, it measures 5.18V.
I have an old Galaxy Tab 2 10.1 that I often charge via the computer's USB port, although it takes a long time, and it's battery is still fine after almost 3 years.

The battery app from the play store probably does the same thing just shows a status as a replacement of the health, you can see the status with logcat occasionally you will see something like this ---
you might need root for some of these commands., you can use Terminal Emulator , adb shell, or sshd to access these commands.
Logcat::
1.
"D/BatteryService( 934): level:83, scale:100, status:3, health:2, present:true, voltage: 4091, temperature: 234, technology: Li-ion, AC powered:false, USB powered:false, Wireless powered:false, icon:17303447, invalid charger:0, online:1, current avg:-378, charge type:0, power sharing:false"
2. (shell)
dumpsys battery
will output something like this
Current Battery Service state:
AC powered: false
USB powered: false
Wireless powered: false
status: 3 < - unplugged
health: 2 <- health:2 would translate to good , health 1 would be excellent (though I have never seen a 1 status , 3 poor, 4 bad
present: true
level: 83
scale: 100
voltage: 4114
current now: -140
temperature: 248
technology: Li-ion
3. (shell, you can check out other files in the /sys/class/power_supply/battery/directory but be careful not to modify them)
cat /sys/class/power_supply/battery/health
