Isn't it just a USB power plug ?
If so it will be surelly faster than charging from your PC but I wouldn't pay 17 dollars for it. I mean, it's identical to the s2 orignal charger only with a removable usb cabble right ?

That looks like the charger for my old Captivate. My SGS2 charger does not look like that. OEM chargers should be faster than generic chargers because Samsung hardware doesn't allow the generic ones to charge as fast.

Yeah you are right but why they have called it a Rapid charger ????

Okkkk buddy... Then why they have given it rapid tag...doesn't it stand for fast charging???

It looks like a scam!

if you have your samsung original charger a custom kernel you might want to change the USB voltage settings while charging.
The problem with fast charging it is because it reduce the battery life. Its cool to charge the phone fully in no time but in short-mid term it is not something you should do

doesnt harm the phone or battery???

Not on short term.
But if you do that everyday the battery will suffer and will loose effective power.
Also if you force an higher usb port voltage on the phone make sure you dont use a computer usb port as electrical issues may occurs.

The sgs2 doesn't even use the oem at full capacity (1000Mah) it only chages @ 450 Mah because of samsung's software limiting the input. Use a custom kernel such as siyah to enable faster charging @ 650 Mah which speeds up the charging to about 2-3hrs

mate the best cure for slow charging times is a desktop charger and a spare battery you can even take it to the next level and get
2x 2000mah batteries
1x genuine samsung desktop battery charger/stand
thats what i do and its so nice not having to wait the 3+ hours it takes from empty to max , i abuse the phone , then just swap batterys and put the empty one on charge
seriously samsung gave us a removeable battery and a micro sd slot something thats getting rare these days in high end phones so grab a spare battery and a memory card and make the most of them lmao
edit
i spent approx £50 on batterys and a charger from amazon and its the best thing i done i literally never have to have my phone plugged in at all

Mate..how much time desktop charger takes for 2000mh battery ????

it will take approx 3-4 hours from flat to full , if you have 2x 2000mah batterys one can be charging while your using the other one
its what i do and it works great

Chargers?

ok guys i just got my travlers pack charger with the extra battery now i see the charger has 5v with 0.7amp i look i the charger with my phone it says 5v with 1.0amp , so which charger would give me a faster charge time? Thanks.

Is there any alternative for the fast charger used with xperia s ? Which can be bought from flipkart maybe?

Just find a usb charger with the same amperage. Its just a power supply, the phone smart charges itself.

What the heck is smart charging?

It would be good to get a 1.5A charger which I dunno

What I mean is, it doesn't matter if the charger is for a Sony, Samsung, Motorola. If it has a usb port and is close to the same amps as stock you can use it.

Sorry for the half message.
True ,I understood your message , I just don't know which will be the cheap and best USB charger which gives at least 1.5A output
Sent from my Xperia S using xda premium

Just go to the store and read the labels to see which charger has the best specs for the best price. I use a Nokia charger on my phone that I've been using since I owned an N85. It goes to 1,2A. My Xperia S didn't have a charger in the package, just a USB-cable. But that Nokia charger works a lot better than most Samsung chargers I've seen (those are tiny and only go up to 500mA). Tiny chargers might look easier to take along, but you better get one that's a bit bigger and saves time on the socket.
Can't really help you on choosing a particular model, we're from completely different parts of the world. Just know that you can't really do anything wrong, the worst you could do is buy a charger that's a bit slow if you don't look at the specs.

sony fast charger (ep850)
sony have fast charger and work good for xperia s
just go to store and buy ep850 sony
ep 850 charger have 1.5A and very good i buy it and and it work very good
sorry my english is bad
thanks

1,5A is too high for a phone, 1.0A or 1.2A will be nice. the original charger is 0.85A and car chager is 1.2A

[SOLVED] Charging problem

I have read somewhere that when you charge your phone and you use it that it still should charge.. But when I use my phone while charging it discharges and pretty quickly too.. Is this caused by a bad battery or is my charger broken?

If it takes too long to get a full charge when using the power socket you might want to try to check your battery.

Are you using the original charger and cable? I thought I'd read somewhere that not all USB cables can handle the 2 amp current. I'm not sure how accurate this is.

Original charger? The original charger can provide 1.0A, check what's written on your charger. USB cable could also be the problem. Other tips is to lower the brightness, it will save battery.

I had this problem couple of months back. Changed the charger and that fixed the issue. Try changing the cable or the charger itself.

Thanks I got it figured.. I had an USB extension cable because the orginal cable is kinda short. But apparantly the extension cable couldnt handle the amps

[Q]Charging

Hey guys, I'm having a problem. So recently, I have been noticing that my charge is much slower, then I realised that even though the charger is plugged to wall socket, the charge speed is as of a USB charge. Any suggestions on what I should do?
Sent from my GT-I8150 using xda app-developers app

Maybe the battery calibration will do the trick ..

Pristine way right? How that can be happening? Maybe you can use fast charge from google play, as sir arco make it compatible with his roms. But actually it is not necessary to do that as you plug in to wall socket. But you can give it a try.

No. That's battery calibration apps. This is fast charge app: https://play.google.com/store/apps/details?id=nz.org.winters.android.gnfastcharge
Before connect to charger, open the app, give superuser permission then on it. The plug your charger. It should change to ac charge. Actually it function as if we want to charge it using usb and plug in at laptop, or maybe in car that have usb. So we don't need charger that can plug in the car. Give it a try. Cheers

LoL. Another beliver in myths and little green ghosts inside an Android phone. No offence meant, but it´s a pain explaining over and over this is just a myth and giving real facts many people still ignore even after being proven why it´s a myth.

Don´t belive in what some apps are you showing. Take a DMM and check the voltages yourself. Your charger should output 5V and your battery should have 4.2V when it´s fully charged and something between 3.0-3.6 when discharged.
Myabe your charger is dying or its the battery. Either way no software will fix this, nor whiping battery stats which Android is doing on each reboot, nor green Android ghosts.
First check the voltages and try an other charger. Secound if needed replace the battery against a new one because it may also be the battery which is dying where it´s internal resistance is growing and so reducing the charging current.
The max charging current should be around 0.7 x capacity as charging with higher currents will decrase its lifetime.
It´s not worth using FastCharge. Neither for the lifetime nor for the risk to get your battery exploded, as this is growing too with higher currents.
Currently cargers are dirt cheap. You can get one with 1Ampere output for around $3-4. A replacement battery costs about $10-20.

I recently bought a new battery, which ironically is $39 for a non-original battery, whereas the Samsung battery was charging $52... I think the cause is the charger, it has been relentlessly supporting me for one and a half years and I think its time to say goodbye to it.

Yes, I have had already a lot of chargers dying. Disassembled them all and they all are using the same circuit. They are made dirt cheap and it´s production costs will be about 50 cent. The only better quality circuit I came across was from a charger made by Sony. This one was even worth to be repaired but if it comes to the other cheap ones I´m just throwing them away and replacing with new ones.
Just wounder why the batteries are so expencive in your area.
