I don't know if it's a kernel/rom problem, or a hardware controller that's at fault, but ever since I got this phone charging in car chargers, computer usb outlets, and even alternate wall chargers has been painstakingly slow!
It takes forever to charge, and takes a dedicated powerful wall outlet to even do anything.
Anyone else experiencing this?
The default Samsung Provided Wall outlet charger provides .7A of power, while USB provides .5A of power max. Also what percentage do you charge it at, and can you take a screenshot of your battery usage graph?
The 3rd party chargers that designed for iDevices are not recognized as AC chargers and will be charging at USB mode which is much shower.

According to Entropy512, here is the quote:
Improved battery charge algorithm for faster charging - Initial research indicates we have an alternate battery charger chip (MAX8922) that differs from the MAX8997 used in the I9100. We DO have an 8997 also - but on our device for some reason Samsung decided to use an alternate chip instead of using the 8997's built-in charging. This means we have far fewer options (90,400,660 mA) in terms of charge rates compared to the I9100 (from 200 to 950 in 50 mA steps). So we might not be able to implement any fancy charging algorithms.

So if I am understanding correctly we were limited to 660 mA at max and unless some way to change it is found, there is unfortunately no use from more powerful chargers .

Perhaps you have either a faulty battery or a faulty charger.
Here is a link where you can buy a new battery and wall charger for under 8 bucks for both with free shipping!
Check it out here: http://www.ebay.com/itm/1800m-BATTE...045605?pt=PDA_Accessories&hash=item43aa9a4465
Put your phone in to power saving mode and see if it charges faster.
Other wise exchange it under warranty.
I've experienced that this devices charges significantly slower then my previous devices.
I found it odd when I saw the stock a/c USB adapter outputs at .7mA so i did a starch and found an article out there with a statement from Samsung stating that their devices are designed to charge slow because it's healthier for the battery.
I don't know if the charging current is restricted by some code in the kernel or a physical chip in the main board.

It is true that slow charges do increase the overall life of the battery. Also not charging it all the way or discharging it all the way will keep the life of the battery. If you discharge the phone all the way down, it will take much longer to charge than charging it back up from 20% or so.

Can you please post the output voltage and amperage for the battery charger on that accessory? Should be either on a sticker on the bottom of the device our written in fine print on the charger.
Also just to double check, it does not charge a docked device, just the spare battery?

Physical chip. However on other GS2s and original GalaxyS phones, the chip was fairly controllable by the kernel.
Ours isn't - it has three settings. 90, 400, 660 mA.

It is 600mA, and it just charges the spare battery.
I strongly advise against buying third party batteries or chargers. The Galaxy S 2 (AT&T version) uses a battery with NFC technology. Using anything other than an OEM Samsung battery, or an NFC compliant battery could cause damage to your device.

A lot of chargers will be rated less than the stock charger. Especially cheap car chargers. In that case the phone can only draw at the charger rating.

The values listed on the charger is the max output it can provide. If the setting on the phone or the hardware is set up to only pull 1A, then it will always pull that unless that is more than what the charger can provide.
That being said, you should be able to take the battery out and charge it faster separate from the phone. I've always read, though, that charging a battery faster ( i.e. turning up the current) will/may reduce the life of the battery

I have a Touchpad charger and it can be used, though I noticed that the phone got hotter than normal, IMO. The phone comes with a 1.0A combo wall charger with USB cable. Interestingly the Samsung stand and battery charger that comes with the spare battery comes with a .7A charger but the charging unit itself is 500mA/1A on the input with output at only 4.2v @ 450/900mA.
Wondering if anyone has tried it? I remember reading that the wall charger from my Tab 10.1 was more powerful than for the phones because it would take FOREVER to charge. Wonder if it's compatible with our S3?
Anyone?
I believe that anything that charges on USB is just getting 5 vt, so any charger would work with any phone/tab if it is charging through USB. I would guess that the wall chargers are also putting out 5vt and would therefor be fine with any mini USB plug charging device.
Easy to check, plug it in and see how it works. (Buy insurance first )
Yes,
I have been using my tab 10.1 charger since the first day I got my sgs3.
It DOES charge faster, about an hour for a full charge from <8%
No problems I have noticed, and I am using blazer rom.

Any modern device will limit its own current draw to what is needed to do the job. While it is certainly possible for a charger to be underpowered resulting in slower charging it should not be possible for a charger to be overpowered. That is, there is some maximum charge speed the phone is capable of and that limit is expressed as its maximum mA draw. a charger that sources under the max mA will be slower than one that meets or exceeds it. A charger that exceeds the max mA will not charge any faster than any other charger that also exceeds the device's max mA regardless of the differences in their source capacity.
So, if that makes sense to you then you should know it ought to be safe to use a powerful charger and that if faster charging results then the stock charger is in fact underpowered for the device it was paired with.
Disclaimer: Any engineer worth his salt is going to current limit the charging circuit on the phone. However, if this were not the case then providing increased charging capacity will most certainly damage the device.

Any USB wall wart that is 1.5 amps - 2.1 amps (1500 - 2100 mA) @5 volts will work. The more amps the faster it will charge. In a pinch you could use a 1000 mA charger, it will just take longer.
Alright im confused.. Which is faster mA or A?
And by the way im not asking about the power here but a replacement.
Thanks for the infos though

Congrats, you passed electricity 101.
Keep in mind that batteries can be fickle creatures. Sony delivers the XTZ with a 1500 mA charger. Based on that alone, it's probably best to replace the original charger with another 1500 mA charger. While you can certainly use more than 1500 mA and it will certainly charge faster, in the long run you may end up shortening the battery life. There are only so many charge cycles to be had in any given battery and quick charging can put an extra strain on a battery that wasn't manufactured to suck up power that quickly.
In a pinch, use whatever you have on hand or can find. For everyday charging, its best to default to what the manufacturer recommends.
The Apple 12W one works perfectly fine and charges the tablet so much faster!

Without doubt the best charger I've used for the money. It keeps up with battery drain on heavy use (Full HD video+Net+ others...at the same time) Stock charger does not. At first glance it does seem expensive but does the job very well.
I sent Sony a link to the Apple website for these as it's much better than the POS charger they give you with their £400 "Flagship" tablet. Well worth the £15 price tag.

Well, yes and no. Watts, Amps and Volts are all different measurements for different things and it can be quite confusing to figure out to the uninitiated. Watts is a mathematical calculation based on Ohm's Law. Watts = Volts x Amps
All USB devices accept a maximum of 5 volts. USB standards cap the max power delivered to a device @ 5 volts. Most standard USB ports deliver 5 volts @1 amp. Newer computers and specially designed charging ports can and do deliver more than 1 A via USB but they all deliver a maximum of 5 volts.
12 watts divided by 5 volts = 2.4A
If you look at your charger you'll see the output amps listed as 2.1A or 2100 mA.
Sony's included charger only delivers 1.5A or 1500mA, so yes it charges slower and when the tablet is under high load, has a hard time keeping the battery at 100%.
The real concern here, is what effect does delivering 2.1A of current to the battery day after day have on the useful life expectancy of that battery? I don't know the answer because I don't know anything about the battery that Sony uses. It's possible, if Sony, used a top quality battery, that charging with 2.1A will have no effect at all and Sony just wanted to save a buck or two by including a weaker charger in the box. On the other hand, Sony may have deliberately used a battery designed to accept 1.5A and included an appropriate charger.
As I said in a post above, apart from the battery overheating while charging (if it wasn't designed to charge @ 2.1A) and a reduced useful life of the battery, there shouldn't be any real problem using a "slightly" more powerful charger - up to a point. Charge with too many amps and the battery will probably explode or at the very least melt, potentially causing a fire if left unattended.
When talking to Sony, the question you need to ask, "Is the battery rated for 2.1A or only 1.5A?"

Definitely. More current (which is what Amps measure) means faster charge times, as long as what is being charged can accept the current being provided. You should be fine, but what do I know. PM me in six months and let me know if your battery still last a reasonable amount of time - then we'll know.

You're kinda right, but kinda not....
The charging circuitry inside the tablet is what regulates the charging current, not the 'charger', it will have min and max currents (the thing we plug into the wall that we all call a charger, is really just a power supply, there's no charging circuitry inside it.) That's why it doesn't charge from a standard usb port (which is 500mA) so, if it's charging faster with a 2.1A power supply, then it's obviously designed to do so.
Let's say, for example, the tab can accept a charging current of between 700mA-2.5A. Obviously, the charge time will be slower at 700mA than 2.5A, however, if you were to plug in a 5A power supply, the charging circuitry in the tablet will still only draw the 2.5A its designed to. So, don't worry about giving it too much, it's not possible.
Now, I don't know what the min and max charge currents are, but I can tell you that mine will charge (very slowly) from a 700mA LG charger.
And also, the dock for the tablet states an input of 1800mA,
So, we can assume the min is at least 700mA and the max is at least 1800.

technaudio,
That's my age showing. Back before some smart guy invented the wheel, we gave a device power and if we gave too much a fuse would blow. I didn't mean to imply that the charging circuit was contained in the wall plug but at the same time, I failed to appreciate that the Tab was designed to prevent an over current situation.
...now let's see what happens when I give this puppy 15A AC...damn, melted the usb cable...

I guess using modified"boeffla or googymax " kernels will let your phone charge much faster
Maximum rating of the charger is irrelevant, the phone will only draw a safe amount. If you override that limit then you may blow the internal charging IC or rupture the battery.
Don't post questions in the general section.
The S3 can't charger faster than 1A, it will only draw what it can, I've used a HP Touchpad 2A charger since the day I got the phone, it still won't draw more than 1A. You can use custom kernals to draw more, but you'll find lots of stories of people who did it and fried the charging board.
I tested using 1.1Ah, and for the storioes I've read, it's the maximum value you can use with security.
Hi, you can have more than 1A, but you need to change the limit with boeffla (i made it for the USB charge)

Hi, i am getting a new charger for my tablet pc which uses a 5.35V 2A output charger and was wondering whether i can use this to charge my galaxy S3. so that i do not have to carry 2 chargers?
IS it advisable?
My S3 came with a 1A charger, my wife's S3 came with a 2A charger. I used her charger a few times and it worked fine. As of last week my charger is working fine, if I use hers with my phone I only shows "USB" in the battery info and takes forever to charge. I don't know if her charger did damage to my phone/battery but that felt strange, so I stopped using her charger.
