You're trying to draw too much current and the S2 charger is current limiting... which will make it noisy as the feed-forward converter is running outside its design limits.

its dangerous for the phone or charger? or its not that big of a deal?

Stop using the S2 charger. It is rated at ~700mA and your S3 is trying to pull 900mA.
Not a great idea.

use the charger that came with the s3
and u will be good to go
i think that if you use your s2 charger for ur s3 it will damage your battery (but i'm not completely sure about that )

I use an old HTC charger at home which seems fine. And I use the S3 charger at work. Never had a problem.

The s2 charger will not damage the phone it will output only what it is design to no matter what phone you use. That it can be consider normal and chargers do sometimes make some strange noices. My S2 charger did exactly the same noice you described. Also Samsung is not famous about its good quality chargers.

it's weird that the s2 charger is weaker. but it charges my s3 faster than the original s3 charger...

Screen Stops Responding While Charging

Hey guys I was wondering if anyone else is having a similar problem... let me go into some detail...
When I charge the phone with the original Samsung charger or with the oroginal USB cable via PC it charges fine... so not some major problem...
Today I tried charging my phone with a iPhone charger using the original Samsung USB cable...
The phone was charging and the phone was on and working... but the screen wasn't responding at all... tho the power button was as well as the capacitive buttons... but ofcourae since the phone was locked they wouldn't do anything cuz I wasn't able to slide to unlock... it also seemed as if the apple charger got quite hot... but I'm not sure if that's how hot it normally gets...
Now I know normally it says everywhere to use the original chargers bla bla but most chargers aare interchangeable as far as I imagine... have use other HTC or Motorola chargers for other phones... but I do know apple products tend tto act up when connected to other non apple products...
So my question is does anyone know If tthis is normal with trying to use a apple charger with other phones...??
What I was also thinking is the original chargers output is 0.7A while the apple charger is 1A... both being 5volts ttho... maybe that's the problem...??
Any ideas...??

I think there's your problem... You're giving the phone more current that it can handle and can make the phone to do weird things...
I don't know if its just me or there are more that think alike, but I like to think that Apple is Apple and has its connectors/chargers and there's the rest of the world with their universal adapters, so I wouldn't try to mix those two worlds together...
If you need an spare charger/cable, get a standard microUSB cable or charger for any brand and will work without problems. I usually charge my Galaxy S2 with the HTC Desire USB cable without problems.
That's what I'm thinking too... that apple products just don't mix too well with other products... like even their handsfree for the iPhone... if I plug it into my laptop it just restarts... everytime... its weird as hell...
And yea maybe your right... only thing is I like the size of the apple charger being so small and compact hence Ita always laying in my bag... thought I could use it to charge my headset and phone...
Another thing that kinda worries me is the fact that if 1A is too much power... I just ordered a New Trent IMP70D battery pack... it has 2 USB ports for charging... one rated at 1A and the other at 2.1A... hope that's not going to be an issue with being too much power... :S
Tho I have read people are using it with their S2 with no problems...

I had the same problem a while back using a 1A charger after my samsung charger failed on me. So now I'm using my sons blackberry 700ma charger (he lost his phone DOH!) which I think is the same output as the samsung chargers.

If you really want to use the iphone charger with 1A current, then flash siyah kernel and use voltage control app to tune and make your phone receive the whole 1A current.

Hmmm... interesting... I didn't know we could do that... but I rather not change the stock cm7 kernel... hear ppl have issues with compatibility ...

[Q] Can I use a Galaxy S2 charger for Galaxy S3?

It will affect the life of the battery or there is no difference between chargers?
Thank you!
Yes
But,
SGS2 charger rated @ 5V/0.7A
SGS3 charger rated @ 5V/1A
Meaning: Using the SGS2 charger with the SGS3 phone will charge at only 70% the rate > ie take longer..........
Edit: No, it will not affect the life of your battery, could even possibly extend it as the battery is affected by less heat generated.
Then I guess the same applies to using the charger of the SGS for the S III. That charger is also 0.7A.
(I'll be using it since it has a longer cord. The charger of the S III doesn't reach from the outlet to my night stand...
Just buy a longer USB cable that's all i did.
if anyone is ever stuck without their original charger i can confirm i have used my wifes old blackberry charger. my sons galaxy ace charger. and an iphone charger with micro usb cable plugged into it. all worked fine on both my s2 and now my s3. as long as it is micro usb and not crazy high amperage it should be fine.
So as long as amperage isn't too much over 1A, all is ok?

Apparently the SGS3 limits the charge rate to 1A max on AC charge.
SiyahKernel plus the extweaks app have an option to increase this limit.
Personally, I have never tried it, and don't particularly wish to.
So to answer your question, theoretically, the phone will limit the charge rate to 1A whether you're using a higher capacity charger or not. Most likely to protect the battery and charging circuit from damage.

I'm using the S1's one at the moment...same thing really, as the above poster said, might charge slower though.

This is wrong mate.
You CAN use the charger from the S2 even though it is rated 0.7A. It actually is capable of putting out more than that. You can use current widget to check this.
I have checked and on the S2 charger, the S3 draws 0.999A same as on S3 charger..
However, using it for prolonged periods will probably result in a damaged charger. I would use it only in emergency.

I never said you couldn't, just said it would take longer
My official SGS2 charger IS rated at 0.7 A (yours may be different), confirmed but not tested with a ammeter, which would be much much more accurate than any widget.
Can't borrow one from work unfortunately...

Apologies... Just read ur post again.
It won't take longer either as the S3 draws what it needs. The S2 charger will give out 1A although not sure how long it will last longterm.
I've used "current widget" and on quite a few phones now and it's pretty good. It might not be 100% accurate but it's not that far out. On my S2 the different charge modes in Siyah kernel could easily be seen in current widget. Same with my S3... Current widget reads same whether I use my new or old charger..

Is that safe? From what I get from http://en.wikipedia.org/wiki/Usb#Power , no more than 0,5A is expected to travel through a USB cable.
Is the cable we get from Samsung perhaps made for the 1A? It is quite a bit thicker than most other USB cables I have...

Yes , the device will only take what it needs.....no matter what the output amps are.
Devices are built to limits their input current.
Sometimes I use data cable from old Samsung to transfer data or charge.Still no problem.:good:
I've only ever used my S1 charger or my old S2 and now S3. Every so often I use a Nokia cable paired with my galaxy tab 10.1 charger and haven't had any problems.
Sent from my GT-I9300 using xda premium
Most devices won't draw more than they need. I've used anything from a 0.3A charger through to a 2A charger... in my experience the S3 doesn't charge any faster on the 2A, but it definitely charged slower on the 0.3A (perhaps because it was limited to a max output, I may have to see what this "current widget" says.
Here's the catch though, it will charge faster on a higher amperage during heavy use, than it would on a lower amperage.
how long s3 make to do full charge, i bought un old one, & after 2 hours il indicates 75% only??
I charged mine for about 2 to 3 hours.

i am using a 'Sony xperia x10i' charger with my S2 and there is no problem as such for now
So IMO it doesn't make much of a diff with S1 and s2 chargers for now as long as they are micro usb for u
can anyone please tell charger specifications of s1 and s2
Google.

I use the same micro USB charger for many different devices both at home and at work. The handset (kernel) is what determines the load that it pulls and as long as the charger can deliver it no harm is done* (to the charger). I have yet to find a handset, even through custom kernels, that can draw more then the charger can supply (assuming charger is in the wall and not connected to a computers USB port).
* If you are playing with the charging current on a kernel then you can damage / explode batteries and burn out main boards on handsets.

charger melted

This is the charger for my galaxy tab 10.1
Is this common?
Whats the best option now I dont trust even a new one now as its not that old anyway.

I'm interested in this as well. My charging is getting crazy hot and I'm worried that I may end up in the same boat.
I think, any 5V USB charger will do if enough Amps provided

[Q] does galaxy note 2 charger fit gs2?

my galaxy s2 charger doesnt work anymore so i decided to order a new charger from ebay and the question is will gnote 2 charger harm or cause any damage to the phone because of the twice higher output (1 and 2 amp) i know that the phone might charge faster but im scared that it will ruin the battery.
thx guys

Yes,you can use a Note 2 charger
The phone will use as much current as it needs. I think the s2 is limited to 650mah
correct me if im wrong anybody.

Yes u can use....stock max input is limited to 650mah unless u have used a custom kernel with the input current increased
