My original charger is lost so I need to buy a new one . At this point I am charging with my friend's charger .
I will not buy the original one as that is costly . So tell me which charger I should buy for comparably fast charging
You need to find a charger which has the same kind of ma rating for similar charge speeds, the current (ma) is basically the limit on how fast it will charge.

I still recommend the original charger They may cost a but more but it will ensure you that you are using the correct one

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
| message swifted from Note, travelled in the air to gateway and wi-maxed to [email protected] |
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.. >

And take the battery as well with it in half the time!!

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
Using CM10.1 (06-14 nightly) on my One (International), connected to a Belkin 1A USB car charger with a decent quality USB cable. The phone discharges slowly in general use, and quickly when using GPS. Looking in battery settings it shows "Charging (AC)", which would suggest that it's drawing the full 1A for charging. I didn't notice this problem on stock Sense, although it's been a while since I used that.
Has anybody else seen anything similar on their One? Is there any useful information I could get from a logcat to give to the CM devs?
Thanks in advance,
Jon
OK I checked on stock and it does drain similarly. Should I just get a more powerful charger or could I have a hardware problem? Tried with 2 different 1A car adaptors.

Have you got a clamp meter or know someone who has one? That will tell you how many amps are going into your phone. It does sound like the charger though as your charger at home should be similar voltage/amps to the car charger only the AC charger needs a transformer and rectifier to step down the voltage and change it from AC to DC, car chargers just step down the voltage a little (12v-5v) so require little additional size. Probably easiest to swap out the charger, they're pretty cheap

I think you need a bigger charging maybe the charger is not able to provide the needed ampere.

Thanks guys. I've ordered a 3.6A charger which had reviews saying it worked well for high power usage Android devices. So hopefully that'll sort things out. I'll post back my results.
OK, tried with the new charger and a good USB cable, and all is well. Even with GPS and Spotify running together the phone still charges slowly.

It's probably not about the Amp rating of the charger. You probably had a cheap charger unit that couldn't deliver the amperage the phone needed either cos it was using cheap parts or something. A proper 1amp charger will still do as well as your new 3.6A charger

Yeah that makes sense. I just thought that if I got a massively over-specced charger then it would at least manage 1A Would have expected the Belkin one to work properly in the first place but never mind.
Hi,
Can anyone recommend a decent USB cable for my sons N7?
Need to get a replacement, but the ones i currently have are not beefy enough to charge properly.

Same problem, can only find pathetic skinny fragile things.
I have used this cable without any probs
AKASA part no AK-CBUB05-10BK
bought from CPC order code CS20881
Try a flat ribbon cable, Amazon Uk have them http://www.amazon.co.uk/s/ref=nb_sb...onics&rh=i:electronics,k:flat micro usb cable Various lengths and colours. I use a standard 1.2mtr blue one that I bought last year.
I'm using Logitech cable for charging (got it with the mouse) and Nokia cable for PC (they are always connected, that's why separate cables), so get one of those.
I've only had problems with 3 years old Samsung cable because it kept falling out (it stays in on my SE phone)
I really doubt beefyness of the cable affects charging though. I charged my tabled on just about any cable I've found laying around in the house with no problems
The reason as to why your charge cannot keep up is most likely due to using a charger with lower amperage (i.e 1amp/1A).
As long as you purchase a 2amp charger and compatible usb cable, then you shouldn't have any more issues with draining the battery faster than it can be charged thanks to the 2amp charge rate.

Thanks for the reply guys, this is using the Asus charger that came with the device, just that the original cable split, so I need a replacement.
Have looked at the cables, might get one of the flat ones as they look good.
Cheers,
Paul.
Just to let you know I bought the flat ones and they fit and work really well.
Thanks for the replys all.

Trick is to get a short a cable as you can. The impedance really effects charging. The difference between my stock and a 6' cable is like a 60% drop.

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.

Need your feedback before i purchase a high current wall charger.

I lost my xperia z' s charger and so I brought a samsung note 2 original charger, since it is a 2000mA charger it can charge xz faster than its original cahrger ( xz can support 2 - 2.1 A charging current at max), and then due to loss of my usb cable along with the charger, I bought a 1.5 mts china cable. Ofcourse it do the charging, but its charging time is slower than what I get using a 1 mt high gauge nokia cable.
So this is what I learned, to get proper charging, we need to use original charger and a good quality high gauge usb cable too.
But since I wanted a lengthy cable of about 1.5-2 mts, I am going to buy a high gauge lengthy cable. Now here is my question;
Do anybody knows an app which realy works on xperia z which can detect the charging current properly?? I tried current widget, samsung charging current apps, and few others, all those apps shows some random numbers which changes randomly ( eg :- 300,206,540,750) , some does shows -ve values also, which totaly make no sense since I am plugged into a 2A charger!!
Thanks in advance.

Try Android Tuner app by 3c(available on playstore)
In app>>battery manager>>status shows the battery flow also the current capacity and a lot of other info
Also a negative value does makes sense...once your battery is fully charged the current flow is "cut-off" to prevent overcharging the battery and eventually damaging it.

I already have that, think its not correct, coz I used a 2amp charger, ( note the charging current) this is why I asked. I think the stock kernel is not reporting it correctly???
