My GS3 takes about 3-4 hours to charge from 0% to 100%. I am on stock and am using the OEM wall charger that came with the phone. Is this normal?
Mine takes around an hour or two I believe it used to take around the same as yours but it doesn't last as long. But how long does yours last

Mine take over 2 hours from 5% to 100% using stock wall charger,,, 3 to 4 seen like a lot.
The answer is... it depends.
If you're charging with the phone on, it will take longer, if you're charging via a usb port, it will take longer.
If the phone is off and you're using the stock wall charger, you're charging at a maximum of one amp. If you have a stock 2100mah battery (2.1 amp-hours) and your charger is 100% efficient (never happens), the best possible 0-100% charge time is... 2.1 hours, it really is that simple
Now, you're not getting 100% efficiency, plus the way lithium batteries charge, at around ~50% capacity, the charge current steps down gradually from 1 amp to nearly 0 amps, so your real full charge time with phone off is probably going to be closer to 4 hours than 2. The step down is necessary to avoid over-charging. The logic (usually in the battery itself for phone batteries) to determine full charge is when the battery reaches 4.2 unloaded volts. Charging current will increase the voltage reading, so as it gets closer to full, charge current is gradually stepped down to maintain the 4.2 volt full charge state. As the current approaches zero and volts stay at 4.2, the charge controller knows that the battery is full.

3 hours is the average using the included 1amp A/C charger.
Charges 10% about every 15 minutes for 0% to 90%, and charges the last 10% in about half an hour.
(don't bother trying to charge using your computer's 0.5amp usb port, though; takes forever, especially if you're using it while charging)
There are reports that the charger that came with the s3 is garbage.
I was using the s2 cable to charge and it took approximately 1.5 hours.
Now it's taking 3 - 4 hours.

The charger that comes with the S3 is NOT garbage. I tested charging times against a "better" 2.1amp charger about a month ago and there was no difference. (If your custom kernel supports "fast charge", then there'll be a difference, but your battery will suffer. Better to stick with 1amp)

Flashed JB today. Phone currently charging. Started charging at 2%, now at 41% and it's been 45 min. Estimate completion time, 1 hour 45 min.
So the culprit is not the USB charger, but rather something I had installed on ICS. I suspect it is the launcher I was using, which was GO launcher. Prior to JB, i was using apex and it was charging a little bit faster than GO, but still wasn't acceptable. I think it was 3ish hours for full charge.
My current JB setup is pure stock launcher and apps.
With stock charger it takes my phone approximately 2.5 hours to go from 5% to 100%.

I can confirm that,my AT&T S3 has been charging with that charger for 6 hours and I am still showing a 50%,so I had to grab a Motorola charger and it went up from 50% to 73% in half an hour.
Freaking Samsung,there's always something.
I'm on Slimbean 4.2.1 RC1 w/ lean kernel and my phone will usually last (with average daily use) about 3 days on one charge. The rom/kernel supports fast charge so I can get it from 0-100% charge in under an hour and a half. On stock rooted rom I was getting maybe a day and a half of battery life. Darned AT&T bloat lol

So how do we decide the most efficient charging method possible? How do we look at the Amperage of the battery and the amperage of the charger and decide what's best?
Also what's faster? Wall charging or fast/quick charging to a USB line?

This doesn't mean you battery is "on charge" for all the time... once the battery is 100%, the charge changes to something called "trickle charge". At this point charge does not happen continuous, but like a trickle to maintain the 100%.
Pull the phone out at the end of 8 hours of charge, and notice how quickly it goes to 99. Pull it like 10 mins after it says full, and it takes longer to go to 99%.

Higher amps charge battery faster... but... at the cost of capacity... At approximate 10% more charge than the battery is optimized of, it kills the battery by as much as 30% sooner. So its not really worth that. At the same time lowering the amps by 10% increases life by about 20-30%.

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...

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

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...
How long does it take to fully charge your One-X?
Mine is already charging 3.5h to get from 40%to 80%....

Isn't that a bit to long?? My HD2 was completely charged in 2h..

I am no expert, so don't hold me on this one, but I believe your device charge should speed up due to firmware updates and also once the battery has been 'worn' in - just stuff I have seen about.
Can anyone else provide me their charge times? How long it takes to charge from A to B?
Pls mention with wall outlet or USB.
I've noticed this as well. My Arc charges in like 2-3h to full. the One X takes about 2 hours to get to about 60% from 30% (using USB).
edit: wall charging takes just as long.

Interesting reading about lithium based batteries
this is a quote from batteryuniversity dot com
Simple Guidelines for Charging Lithium-based Batteries
• A portable device should be turned off while charging. This allows the battery to reach the threshold voltage unhindered and reflects the correct saturation current responsible to terminate the charge. A parasitic load confuses the charger.
• Charge at a moderate temperature. Do not charge below freezing.
• Lithium-ion does not need to be fully charged; a partial charge is better.
• Chargers use different methods for “ready” indication. The light signal may not always indicate a full charge.
• Discontinue using charger and/or battery if the battery gets excessively warm.
• Before prolonged storage, apply some charge to bring the pack to about half charge.
• Over-discharged batteries can be “boosted” to life again. Discard pack if the voltage does not rise to a normal level within a minute while on boost.

And I also read that charge time should be almost 3h for a full charge(i suppose this is when device turned off). You could get about 70% charge in about an hour if I remember correctly.

using wall charger
Took me three hours with original HTC wall charger and original HTC cable (no extension) to charge from 4% to 100%. Terribly slow!
EDIT 1 : Apparently BWM doesn't show accurate power draw while idle on the One X for now, so my post has become totally irrelevant
I always install Battery Monitor Widget on all my Android devices and monitor charge and discharge constantly.
On my Desire Z, if it's below 70%+ I get a charge rate of about 750mAh from wall socket.
But on my One X, with the same charger (both are rated for 1amp, and both HTC), my charge rate drops to 450+ at 60% battery life.
It's probably a software issue, but charging the One X does take noticeably longer.
I don't think it is a software issue, as the battery pack is larger than before. Also when you are active the phone itself draws large amount of current and it definitely slow down your charge rate.

When your phone is idle with screen of, it shouldn't drain large amounts of power while charging. Can't imagine that has a huge influence on charge times tbh.
And for capacity, my HD2 was charged in about 2H for a 1200Ah battery, this 1800Ah One-X batt should be full in like 3h... not 5 or 6h...
The official wall charger took 2.5 hours to fully recharge the One X
Ok after an amount of charges, it now takes only 2.5h - 3h anymore for a complete recharge.
Official wall charger.
Did a charge on mine this morning from dead, took 2.5 hours to get to about 90%, left it for another hour but it didn't go up the last 10% stayed on 90 even after the extra hour. Off the wall

I'm thinking the same... I don't mind turning it off on a night for the first 2/3 charges but personally this is my only phone (don't have a house phone) so will be keeping it on through the night in case someone needs me in an emergency etc...
Was interesting to read that batteries prefer a partial charge and do not need to be fully charged; which is good actually as mines got around 18% left and I'm about to stick it on charge for the next 8 hours.
I went to sleep last night with the battery at 15%, slept for ~5 hours, woke up, and the battery was only at 50%. Is this normal? Does it take this long to charge for anyone else?
For reference I'm using an HTC charger from a previous Android phone, would using the Samsung charger make a difference?
Yes it seems like too long for too little of a charge. Give the Samsung one a shot.
Your using a charger that at very best pumps out 1amp
The default note 2 charger pumps out 2amps
In other words your charger will take twice as long as it should to charge your phone

It's from a HTC wall charger. I changed it to the Samsung charger that came with the phone. Will let you guys know how it goes when I go to sleep tonight.
Will the USB cable make a difference? I have a super long USB cable that I like to use instead of the short default cable that came with the phone.
I know about the 1 Amp / 2 Amp charger ratings, but unlike the original post:
I have my Motorola Xoom 10.1 plugged into the wall, and i use a USB OTG cable from the Xoom to charge my Note 2 overnight (so to only use 1 plug socket).
So i assume this is providing 1 Amp or even less to my Note 2.
I often have it charge my Note 2 from 5% or less all the way to 100% in under the 6/7 hours sleep i get.
Somehow the original posters 35% charge in 5 Hours seems very slow.
with my Samsung box set usb cable, it still takes 8 hrs to charge 100%. sometimes the red led is on but without a single percent charge. I am talking about charging with the usb connected to the laptop. if plugged in power, it takes less that 3 hrs for a full charge.
I remember my previous win7 was perfect, may be the new win8 is having some problem or not, I don't know?

My Xoom must give out some good Amperage if i can get a 100% charge in 6/7 hours then.
The "only" thing that matters is the voltage.
The included charger puts out 5V(+-5%) and 2A.
Too little voltage, and it won't charge.
Too much voltage and you will burn a fuse or the charging circuits in either the phone or the charger.
The phone chargers (no matter what brand it is) are within the limits, so don't worry.
The current (Ampere) shows how much power your charger can deliver at a given time, but the phone itself decides how much current it can take.
A standard USB-port (1.1) gives out 5V and 500mA.
I've built LED cables based on this.
USB 2.0 and higher are supposed to be able to give up to 1500mA under certain circumstances.
My motherboard has a pair of special USB-ports which can recognize cameras, phones, etc. and charge with a higher current and even without having the computer turned on.
While charging through USB-ports a full charge takes ages for me, 6 hours while sleeping will never even charge close to 100%.
On the other hand, charging though the adaptor that came with it or any other adaptor that can pump some juice is blazing fast... 3-4 hours and it's back to a 100%.
Okay, this will sound too silly but this worked for me! Encountered and suffered from the same problem..
It used to take 8 hours to get fully charged...but in time i noticed this silly and weird thing...should work though..
Before putting the phonw on charging, kill all running apps...then when you plug the charger-DO NOT TURN THE SCREEN OFF BY YOURSELF...let it sleep automatically. And it'd get charged lighting fast...it worked for me!

If i put my Note 2 on charge where its at 25% battery, in 30 mins my battery gets charged to $85%! And you should ALWAYS use the charger that comes with your phone instead of a charger made for another phone. The HTC charger is designed to charge that HTC Phones battery. Each charger is different in the sense it provides different amounts of power. The Note 2 battery is huge so the Note 2 charger is designed to push a specific amount of power to it to charge it in a reasonable time.
For e.g. If you use the iPhone 4 charger to charge an iPad, in 5 hours it will charge the iPad to approx 50%, and if you use the original charger to charge the iPad the iPad will be more than fully charged. Thats because the iPad charger is designed to accommodate the huge battery inside the iPad.
Also i read an article not too long ago that said that alot of science goes behind these smartphone / tablet chargers and how its dangerous for the charger and device / battery if you start mixing and matching chargers.
My $.02 cents!

from 0% do 100% 2hours 30min. its very fast for 3100mah baterry.
I use my iPad3 charger to charge my N2. It juiced up faster and my N2 does not heat up when it is fully charged.
I use my iPad3 3.1amp in car charger as well when I drives around

Now here's the kicker... It's currently unavailable...but two days ago when I wanted to make this thread is was not even listed on Amazon, so possible restocking ? I don't know.
I killed my battery to the point of total shut down by about midnight Saturday night. When I got up about 930 am I was fully charged. Now I know we've seen longer run times leaving the charger on after 100% pops up, so to speak to that I am on 94hrs run time and have forgotten how to check Screen On Time...
I am now at that dreadfully annoying -10% level. So I can use the phone all day on 100% brightness but it will chime in all day to warn me of the coming Powerpocalypse to come :laugh:

If you rooted your device you can put an xposed module on that will eliminate all low battery warnings.
On your setup, I don't really see the difference between it and using the OGP's standard high-power charger. The cable isn't going to do anything, as far as I can see. And the charging port is 8A/5 ports — from what I've read it adapts to the device to allow it to pull what it needs within that allotment, thus I don't see the OGP pulling more than 1.8A. So, my question to you is, you've tested the standard 1.8A charger against your setup and you get X hours reduction on charge time?
FYI, I don't have the ZeroLemon pack. Thinking about it but might upgrade my device to the GP2.
I have, it took a day and a half.

36 hours to charge?
Most using this pack state around 12 hours. Seems something is wrong if it's taking 36 hours to charge with the standard charger that comes with the OGP — normal battery charges in less than 3 hours. I've seen where some zerolemon packs hit 100% but are actually only half charged, thus causing increased charge times. . . . strange stuff.
Using Yoobao 2 Amps wall charger
My zerolemon (9000 mAh) only took 10 hrs to charge. And standard battery (3140 mAh) took 2 hrs using Yoobao 2 Amps wall charger.
I was hoping someone could tell me where to find 4A or 5A wall charger near Jakarta.
My zrrolemon zero lemon takes about 12 hours to charge AMD my standard battery takes about 2-3 hours using the stock charger

Anyone else notice that with the supplied charger charging ins't what it should be. My iPhone 5 charged almost twice as fast as this phone. I find it kind of annoying. I did order one of these chargers hoping that solves the issue.

The supplied charger is charging rapidly no doubt.
I guess not less than 1% per minute - particularly when below 70%..

No its not. Especially when your using the phone and its on 5% plugged in. Takes forever to reach 6%.
I'm having literally no issues with charging from dead to 25% in about 15 minutes. 2 hours to 100% im very happy with the speed of charging and this is using my m8 charger as the m9 one is still sealed in box.

I've been using the GS4 charger, with a high output cable. The Samsung charger is 1.5A where the HTC m8/m9 charger is 1.0A
the supplied charger is definitely giving 1.5 amps to mine. charges up pretty quick. with a quickcharge 2.0 charger it's crazy fast to charge.
One thing to note is it will take a faster charge the lower the battery level is, which means more heat. if you're also gaming with it, you could be bumping against the battery charging cutoff temperature. I only ever saw this happen on my Tegra HOX+. IIRC HTC has the notification LED blink in alternating green and orange/red when this happens. I'm guessing you would have mentioned temperature in the OP if this was the case, but I figured I'd bring it up.

Just spread your arm, pick whether HTC M8 or M9 charger, and read upon it.. 8)
Both M8 and M9 chargers are - 1.5 Ampere.. furthermore both handhelds are charging fast - otherwise if the cable is a problem..

Sorry, meant it was 1.5a for HTC and 2.0a for the Samsung one. Didn't have them on hand to check.
iPhone 5 battery is 1,440 mAh... M9 battery is 2,840 mAh. 50% charge of Iphone battery doesn't equal 50% charge of M9 battery, in terms of charge time.
I believe the rate of charging to decrease while you use it to prevent the phone from overheating. (My M8 does this as well)
My stock charger is fast, and my quick charge 2.0 is crazy fast.

If you are using your phone and charging at the same time, it will take longer to charge....
as someone who had a nexus 6 with turbo charging. this is bad. charging is so slow.

Yeah, this. I got an HTC Rapid Charger 2.0 for it just to be sure since I knew with certainty it's Quick Charge 2.0. In retrospect perhaps not the best move considering I'm essentially incentivising HTC for not including one in the box from the get go, but whatever.

Yup i got the same issue gonna take me 6-11hrs to charge and its very slow charging
I had a similar problem to OP. The second night I had my phone I plugged it in at 11 pm with about 5% battery left and went to bed. At 5:15 the next morning (6 hours later) it was only at 85%. I can't tell if there's still a problem or I just think there is because I'm paranoid about it now. I haven't run my battery down that low since, and looking at the charge current with Ampere seems somewhat inconclusive. I may have to run it down and then keep an eye on it while charging to see what's going on.
Something IS wrong with SOME M9 phones (I think)
I have one of the "bad" ones. Mine takes hours and hours to charge, whether on the cable and plug that came in the box, or on any others that I have around - some I know are 2 Amps. I think there is something seriously wrong with some of these phones, based on what I am reading in this thread, and on my own example. I have had my M9 for just a few days.
I'd like to post a follow up to this thread after having the phone for a couple of weeks now.
I've had several occurrences where my phone didn't fully charge overnight. The worst was a few days ago, I plugged it in at 5% and the next morning (6-8 hours) it was at 1%, it actually lost charge. I noticed before unplugging it so I looked at the history in Battery Widget Reborn and it showed the battery level just slowly dropped from 5% to 1% without any jumps or dips. The battery icon at the top of the screen showed it was charging but it died at that point so I didn't get a chance to open Ampere.
I think it's the charger (and/or the cable) that came with the phone. I've tried several other chargers that have all worked reliably:
- The QuickCharge 2.0 charger that came with my wife's S6 charges my phone really fast.
- I have a Kmashi external battery that also seems to charge it relatively quickly.
- Two older chargers that are several years old (both rated 5 volts at 0.7 amps) charge it from around 30% to full in 3-5 hours.
At first I thought it might have been a wakelock problem, but the battery has been dropping so slowly when the phone is just sitting in my pocket that I'm confident now that it's not wakelocks. I don't know if HTC is likely to send a replacement, but I'm going to stop into the Verizon store that I got the phone from to see if they'll replace it.

My phone is also odd when charging.
Half of the time it takes 6 hours or more to charge. If I look at GSAM battery monitor it shows a charge current of around 350mA. If I then unplug the charger and reconnect after 15 seconds I get over 1300mA charging current, most of the time. (It takes GSAM a while to show an accurate reading). Occasionally it will take a few tries to get it right. Once I get a good reading over 1300mA the phone will charge in 1.5 hours like it should.
Something very buggy about this phone's charging circuit. I get the same behaviour with all chargers and cables, even my battery bank.

I use a 2A tablet charger from my hp touchpad. Charges from dead to 100% in 45 minutes.
