Hi everyone.
Recently i lost my orginal charger that comes with GN.
And i decieded to buy a new one.it is samsung branded but for tablet and the output is 2A.
If im not wrong the orginal is 700mA.
Now when i put the phone into charge i feel a little lag and slow down while its charging.
My question is why such a thing happening.?

Original one is 5v 1A
| message swifted from Note, travelled in the air to gateway and wi-maxed to [email protected] |
The original charger output rating is 5.0V 1.0A....well have charged my note many times through LG and nokia chargers but never faced any lags or slow performance..

I am not sure with the note but I have experienced this with previous phones. using different charger of different diff rating damages the battery life

I use both, 1 and 2 A
Anyway the charging current is controlled by kernel.
If I remember right it is limited to 2A
(been a while since i looked into the driver code)
Once i had issues where when my touch response was very jumpy I mean was unable to type a single correct word.. Later on i plugged the charger directly to the wall socket and it was fine. It was a problem with the spike buster, some grounding issues and the charger was original samsung note.. Was able to replicate the same with dellstreak on the same spike buster..

So its safe to use 2A charger.
And is there any advantages to charge by higher amp?
I mean maybe faster charging time.
And the other question remains with lags and performance issue....!

Yes it charges much faster. However as stated before, it might have a negative effect on battery life.
Then again the price of a new battery won't kill us
For now my battery is still ok and I bought my Note last year...
Ok i switched the wall AC plug to another one. And no lags anymore.
I think it was that grounding thing our friend said before.
Currently im using 3250 battery gold.china made. Hope new charger wont couse any problem to this battry.

Just check in the beginning that it doesn't run hot while charging.
Acually it was hot with orginal charger while charging before.
But now its totally fine.

My friend bought an SGN2 yesterday and I saw that the original charger that came with it was 5.0V2A.. I was surprised but i want to try it out.. for sure it would slash the charging time in half.. >

yes it mite damage the battery
Yes the more amps the better so long as the volts match . Better a more powerful, than weak.
The phone draws what it needs no more
It will not screw the batt. It draws what it needs .underpower is worse . The charger could blow...not that way

In my experience using phone while its on charging progress will not effect the process and time with 2A charger.
In any case using 2A is best.
I bought an orginal samsung tablet charger which is match with other orginal accessory that comes with phone.nice....

Following Ohm's law, assuming we have the same resistance (the battery/charging circuit), the AMPs (current) would not rise as long as the Voltage wont rise..
So as long as your charger is pumping out 5v, the charging circuit on the phone would take control of the current.. 2A on the charger simply means it can pump out 2A max when the charging circuit demands that much.. I have a 12V 30A power supply and I'm using it to light some LEDs.. They dont burn out.. They only take the current that they need...
Simply saying, even if you have a 5v Unlimited Amp charger, It wont kill your phone.. The charging circuit will take control of the current limit.. If it senses that there is an overcurrent in the system, it will cut it off.. If you have a charger that pumps out more than 5v (I'm sure that is a non standard USB charger) then thats the time you have to worry..
thats a lot explanatory

so its safe to say 5V & any Amp is ok

Hey all!
Today I got the Official Samsung Craddle. This one to be precise. http://www.smartphoneshop.nl/product/199368/123781/5076/samsung-desktop-dock-for-sii-siii-note.html
However, I noticed it charges ultra slow. It goes like 1% per 5 minutes. Does anyone else have experience with this thing for the Note 2?
Should I return it?
And if so, which dock would u suggest?
Grtz,
Dancol
Anyone?
I can't comment on that product specifically, but I have 2 USB chargers in my car both with a 2 amp output, one's a Samsung product for charging my Tab, the other is a Griffin, both will charge my phone even when using the Sat nav, at about the same rate the actual wall charger works at, so there has got to be something wrong with your unit.
The only way of knowing for sure before passing judgment, is to get a normal car charger with the 2 amp output the phone needs and compare the charging time against it and the dock you have.

The dock says on the bottom 500~1000mAH. That is not enough then?

1 amp will be enough to charge, but will charge much slower than a charger with a 2 amp output.

Didn't know that would pretty much reduce my charge time to 20%. Normally it goes somewhere around 1% per min but with the dock it went 1% per 5 mins!

I have the same dock and it seems to be a limitation of the dock.
I use the charger and USB cake that came with the Note 2, but it still charges slowly (with the phone screen turned off)
If I pull the cable out of the back of the dock and plug it into the phone directly, it charges sit twice as fast.
I think the dock only puts out 1 amp, even with the 2 amp charger connected to it.

Hi guys!
I have recently bought a Nexus7 tablet which has a 5V/2A charger .
Can i charge the i9305 with the Nexus charger (5V/2A) or it will cause problems..?
Thanks in advance!

I'm not sure of the voltage of the I9305 but the more volts = faster charging but hotter and hotter means a shorter life for the battery but it should be fine, I would trade it for faster charging. For amps, I have no clue and please correct me if I'm wrong anybody.

I'm pretty sure that you are saying the opposite way.
You can use more Amp but not more voltage.
More Amp - charges quickly.
More voltage - could blow your device.

AW: [Q] Charge with 5V/2A..?
In principle, the battery would load faster at higher charging current when the battery is capable of fast charging. If not, could reduce the battery life. I believe according to the charging control of Samsung, a current limiter is installed that can always draw only 1 amp. So it brings no benefit to using the charger of the tab. It may also be that the charging control of the current is limited so that is not loaded. The phone should not be harmed.

Should be fine for short term use.I've used half amp one amp and one and half amp car chargers wouldn't go any more than two amps no need to..may degrade battery a little so what there cheap enough to replace lol..easy peasy.. I live in tents an caravans 24/7 use leisure battery's not problem with amps just volts..bless solar panels..
The phone take what Amp it needs.. No more than its made for. 2A is only what the maximum out is for the charger.
You could make a charger with 50A, the phone still dont take more.
The volt is the value that need to be fixed though.
All phones charged via a usb needs 5V, no more, no less.(Usb =5V allways) Most batterys now days is something like 3.7V. Correct me if Im wrong.
Any way, you need a couple more volts in the charger than the battery to charge it.
Answere=Yes.. go ahead and charge.

I have had an HTC HD2 and used it's charger to charge my SGSII and now my SGSIII.
The time taken to charge with that is about the same as the SGSIII charger.
The charging circuits on the phone are smart enough to know that you are charging from a mains' adapter instead of an USB output from a computer and thus adapts the current draw from the system.
I previously did tests on the HD2 regardsing charging times and even with bigger supplies that the 1A one from HTC, it did not charge any quicker.

That charging circuit is made to cooperate with the battery and the rest of the phone.
So only difference you will notice is slower charge time if you are using a to weak charger that cant deliver the right amp.
As mentioned earlier you could use a 50A charger with out any faster charging time. Amps is allmoust of no interest if its not to weak.
Look at electricity as water. Amp is like how many liters of water a sertain pipe could deliver. Volts is more like how strong the flow is. To mouch pressure will destroy the flower. But with Amps you could pretend that the flower demands a certain amount of water and it will not suck more just becaus it could get more.

My HTC One showed an warning message about not using the right charger! I was using the charger from my Samsung Note II. I thought HTC encouraged customers to reuse existing chargers? Anyone else seen this message before? I'll use the HTC charger now in case I mess-up the battery.
Its because the note 2 uses a higher amp 2 i think to charge.
I think it was the carriers that wanted to reuse old ones. But its best to use the one that came with your phone.

It's pretty neat that they warned you when you used a different charger cause if something messes up the battery, your only option is to replace the phone.
I certainly wouldn't want to use a charger that's running at 100% above the systems designed input level. I've been in a room when a L-Ion went boom.

has anyone tried charging from the usb port on a pc yet?
As soon as you plug the phone into a PC it is charging.. Much lower output. Never gonna be an issue
I think its fine to use different chargers , as long as it doesnt overcapacitate ur battery. Note 2's 2amp charger might be bad for the battery because faster charge times wear the battery faster

The phone decides how much current to draw, not the charger.
Imagine the phones sucks the energy instead of the charger pushing it.
Interestingly I didn't see that warning yet besides charging my One with fourdifferent chargers (old HTC, original One, Nexus 7 and a Sony one...)
How about using galaxy S2 and S3 charger I got both, is it safe for HTC one ?

As someone says, phone decide how much power to draw not chargher.
Chargher just transform 230V AC to XY V DC. 2A is just max power he can provide.
But phone will draw 1.5, 1.7 i don't know how much cuz i don't own it yet.
Only problem is if you have lower power chargher then phone want to charghe is that charhing will lest for hours.

Charger acts like sophisticated pressure regulator.
Its task it to take 100-240V~ convert it to steady 5V DC and provide current. How that current is used is responsibility of device internal circuitry.

WHOOOOOSH
Basically I want some advice from people on here.
I've broken my charger, the one that comes in the box. The plastic strip out of the port on the side has snapped off. (I use a 3 metre USB cable in it due to weird plug placement in my room, so the weight may have played a part)
What I have got is a HTC B270 charger from my One S I still have and a TomTom charger that can replace it with.
What I want to know is simple... Is there any pros or cons to using them when I can buy a replacement for a fiver off Amazon?
I'm being serious before anyone shoots me down, I know certain chargers charge faster than others and such.

Is it safe to use wall adapter with more current than the standard 5VDC/0.7A rating for the i9000?
I have in mind 5VDC/1A or even 5VDC/2A. I have seen that several high current product vendors/suppliers do say they are compatible
As I undersatand, the technology of the batteries has the intelegence to request the current from the wall charger, therfore if more is desired than more will be supplied...
If there are any technical or experienced person than please help us understand.
Thanks'
Hi,
I use a 1A charger occasionally without any side effects, but I think as a replacement charger, it might shorten the life of your battery.
Mine is about 4 years old and still holds a full days charge.

Since I assume that the phone Battery has a charger circuit that regulates the current needed then having a high current reserve on the AC charger should not be an issue. The AC charger should even run cooler.
