I have numerous chargers at home all of which have charged my evo, gs2, Nexus 7, etc.
Can these be used interchangeable in the Note 2 without harming the charging process?
Thanks
As long as the Voltage is the same (5V) there is no Problem. But you should have a charger at 2 Amper for optimal charging speed.
I just tried charging mine with the normal microUSB charger I use for every other phone I have had and it took 7.5 hours to charge from 5%-62%. I used the stock charger that was in the box and it charged it in 3.5-4 hours no problem. Seems like the charger in the box charges faster.
reading this thread made me curious, my NOTE II should arrive in about a week, I can't tell for myself yet, what is the A (amps) specification mentioned on the original charger?
as i come from HTC, my current chargers go up to 1 A current. witch is the double A a standard USB port will give unless crossover'd .
thanks in advance!
----
in the wiki thread i found the answer, the supplied charger delivers 5 V 2 A output to the device.

2A! Same as the Tab 10.1 charger.
Filling a 3100mAh battery requires some grunt.
i think even the usb cable makes a difference..
when i use the stock usb cable with the stock charger ..my s3 would charge up comparatively faster than with the other usb cable connected to the same stock charger.:rolleyes

It certainly does! :good:
All electrical cables have some resistance. Very low (but not zero) for quality cables, sometimes quite noticeable for thin and cheap offerings.
From Ohm's Law we know that voltage drop will be proportional to current. A cable with a resistance of just half an ohm will loose about 0.5% at 50mA. That's pretty much nothing. However, at 2000mA the loss reaches 20%.
dude use any charger, just don't use LG charger **** !!!!!
You must use the 5volt 2amp charger and cable provided or a replacement with the same output or youll either be waiting for ever for it to charge or do some damage.
I tryed using my note 1 charger rated at 1amp and guess what? It took about twice as long to charge.
Sent from my GT-N7100 using xda app-developers app
Some of my old 1 Amp chargers aren't happy at all, and will often decide to stop charging randomly.
I though it was something weird with my phone, but after switching chargers it never happened again.

USA official charger
This are the images of the official USA charger that will comes when they release the device in USA
And yes its a 2.0A charger, so the SIII charger isn't appropriate for NoteII.
this is the kind of charger used in Canada, USA, and Latin America, i bought this NoteII in Mexico from an authorized Samsung provider, of course factory unlocked 710usd, like 10,900mxn.
Has anyone tried a 3A charger? Just wondering if this would speed up charging even more than the standard 2A charger.

No, it won't speed it up. It's what the device takes from a charger, and not what a charger can potentially supply. If the device's charging circuit is spec'd for up to 2A current, that's what it will suck out of a charger, not more. You can connect a 30A lab power supply, and it will still be the same 2A (or less) input. To speed up the charging process, you need to mod the charging circuit of the device itself.
Greetings! I was wondering what is the maximum rated input current of the Xperia Z. There's no indication of it's rated input current anywhere on the phone. The supplied charger is rated at 1.5A and I was wondering if a higher amperage charger above 5V 1.5A (such as of those catered to tablets/ipad) would charge the battery at a faster rate before investing in one.
Anyone with any experience using a higher amperage charger on the Z could advice on any notable improvements in charging time as well.
Thanks!
Used a Nexus 7 charger rated at 2A and it charged fine with no detrimental effects. Charging time is about 1.5, hours from 10% to full.

While increasing the Amps will result into fast charging... the bad part is that it kills your battery life overall.
I've tried Sony charger rated output 1500mA
and Galaxy tab charger 2A
phone on, screen off
in 10 minutes charge, both added , just the same, 10% juice.
may try it longer next time.

Great findings! I guess it's safe to say that there is no notable reduction in charging times even with the provision of higher amperage chargers, and that the Xperia Z's power management IC can only take in 1500mA at max.

Charging at higher amperage would generate more heat and this increase in heat would degrade the battery cells at an increased rate, thus reducing the lifetime of the battery in the long run
Well unless you value your charging time (or loss of usable time) more than the cost of premature replacement of battery, then quick charging is for you. Personally, given a choice, I'd rather not charge at a higher current unless necessary, especially when time is the essence. (;

I will post when I find the correct link.
Erm I'm fairly sure that whatever amp you use the phone will only draw a set amount I used a 2500mah charger with my old phone for two years no difference in charging time nor degraded battery life or iverheating , just meant I had one charger for everything lol
That's correct, it's impossible to over-charge or charge too quickly a device by using a charger with a higher current rating than the original charger. Current flow is a RESULTING property of a particular voltage applied across a particular resistance. Applying too much voltage will usually be detrimental, but you cannot SUPPLY too much current. The device will draw as much as it needs unless it is limited by the charger's maximum current rating first.
I've been using an old Blackberry charger rated at much less than 1000mA. It might take a bit longer to charge, but I love the long, supple lead that comes with it.

Can someone explain me this...
My Xperia Z came with (1) Power plug-adapter with USB port + (2) USB to Micro-USB cable + (3) Docking station.
The (1) has Output = 1500 mA written on it, the (3) has 1800 mA on it.
Questions:
Can the USB cable transfer more than 500 mA? From reading USB page on Wiki, looks like it can do 1500 mA - 5000 mA when not transferring data so I should not worry about the cable?
What is the point of including a 1800 mA docking station + 1500 mA power plug? Does the station only charge at 1500 mA when connected with that plug or am I missing something?
Thanks, sorry for noob questions

The charging chip it self support higher current by default, but the manufacturer chooses the charger depending on different factors, design of the phone, capacity of the battery and also their stock chargers available... they will choose the best charger to match... in most cases it will be rated lower than what the charging chip is capable of...
the charging chip has it's limits also... using regular USB cables will only provides the standard current... I've used same amperage chargers as the orignal but with different cable and charging was slower... when I switched to the original cable charging was faster and had the same time as original charger ( same amperage )
When you use the original cable and higher current charger then you will have faster charging...
My Xperia arc came with socket charger rated at 950mA and a car charger rated at 1200mA... and the car charger is really faster but only when I use the original cable, when I used a longer cheap cable the charging was actually slower... even when I'm charging non-Sony devices ( like my Note 2 ) when I use original cable ( wether Samsung or Sony one ) charging is always faster... I don't know why it might be a way to protect the standard usb cable from over-current as the standard USB current is 500mA, so the charger will normally send the usual current unless the device requested higher current then it will negotiate with the charger to send higher current the original cables might have something like impedance between some pins so the phone will detect them as original then they will negotiate the charger to send higher current or the charger might actually use the other pins to send higher current but the phone will only use these pins when it detect the original cable... if not then it will not use these pins and will have regular 500mA charging... I've always faced this when dealing with other cables... now when I want longer cable I just use USB extension cable with the original cable and it will work !

- Yes, the cable can easily transfer more than 500mah. No worries.
- It means the docking station is rated for a maximum of 1800mah - so if you buy a 2100mah charger, the docking station may get warm and if it fails Sony won't cover it under warranty. If you use the 1500mah power plug, then the docking station supplies the 1500mah - it's just a pass-through. The docking station itself doesn't really have additional circuitry.

Can now make some docks/charging clips using sugru and a usb cable
Not sure why the dock would be rated at 1800, unless they've fitted it with some circuitry, a simple micro usb to prongs would do.
I charge mine using the adapter that came with my note tablet which is 2a and also with the 2a output of an external battery pack.

Yes, they're right to write the 1.8A there.
because, not all microUSB survive to deliver more than an amps. They maybe melt. especially the cheap one that have very small and loose contact area.
the pogo pins too... Not so easy deliver 1.8A with pogo pins...
that's why intel processor, have 1000+ pins, but almost 300pins are for power supply only (GND and VCC). Although the chip is only 1.25volts, but the current sometimes about a hundred amps (Core 2 Extreme, Core i7)

Wrong. If you connect a 2.1A supply, you'll see no difference.
Charging rate is set by the phone, as long as the power supply feeding it doesn't "brown out" under the load.
2.1A, 3.1A - doesn't matter, the phone will draw less (I'll need to drain my battery down a bit to determine how much less, it's often less than whatever the wall charger is rated.)
There is a possibility that when it sees voltage on the pogo pin connectors, it increases charge current to a different value than on AC via the USB port. The ext charger handling in the pm8921 driver is really convoluted and difficult to read.
Hi,
I've got my phone with samsung's charger of 1A (bought it from an open store locally - it was the cheapest), so I ordered a Sony Ericsson charger of 1.5A which charges up much faster..
My question is, could it goes even faster?
I've seen some Galaxy Note 2 and S 4 charger of 2A like these:
http://www.ebay.com/itm/2A-USB-Wall...S_Cell_Phone_PDA_Chargers&hash=item5658d7a0bd
http://www.ebay.com/itm/OEM-2A-USB-...l_Phone_PDA_Chargers&var=&hash=item51aabf953a
Could our phone handle it and charge it with the whole 2A power? could it ruin the battery with that high Ampere?
I'm asking this because I've ordered a docking station like this:
http://www.ebay.com/itm/261247762140?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
Which says 1.6A, so I was thinking perhaps theres stronger chargers out there for it..
Thanks!
im not sure about this but i believe the charger that comes with the phone is a 2 amp charger
It can handle 2A through USB port.
Via the charging dock, it can take 1.8A. Is that dock you are linking to an original part?
I have two DK26 docks and both say 1.8A, not 1.6A. Although if you connect a 2A charger to the dock, it'll be fine, it just won't be using the whole 2A input.

The Dock I've linked is a chinese copy, not the original, the one says 1.6A on description on Ebay, Does your original DK26 dock comes with charger too? What input and output is it says on each one? (picture could help much)
Also, how do you know it can handle 2A through USB? is that for sure?
Thanks for both!
The docks come barebone. No chargers included.
The charger included on the box of the phone is rated at 1.5A.
I have a Nexus 7 2A charger and an old Nokia 1.2A charger aside from the included 1.5A charger. All work fine either via USB or via the dock.
I can't notice any mayor difference on charging times, though. 1.2A charges almost as if not as fast as the 2A one. Iphone's 1A chargers do seem to take like 4 hours to charge the phone compared to the standard 2.5h I get from other higher rated wall chargers.
There are no 2A Sony chargers as of now.

It should handel 2.A but I won't remand it. I don't think it's good for battery. But one thing is pretty sure. The phone will heat more up as the charging circuit have to dissipate more excess power. Can not affirm it as I don't exactly know it's made but I'm just saying...
"I know that my English isn't perfect, but I still hope it's comprehensible." Send over the cool Xperia Z
The downside would be possibly shortening the usable life of your battery, because the higher amp charging will likely heat the battery to a higher temp.
There's no free lunch.
To me, waiting a bit longer for charging is worth it to ensure the longest charge cycle life, particularly since the battery is sealed into the device. If it was a cheap and easy replaceable battery, maybe.
Amps don't matter unless it is lower than the specification
Think about your car battery having 700amps but your car stereo is fused for 20amps. Your car stereo gets its power from the battery directly. There is no power regulation. Your device will take only what it needs. It won't effect the life of your battery. Think about the charger you plugged into the wall socket. A wall socket can generate enough current to melt metal. Lower power draw is cooler but really just make sure the voltage rating matches and the amp rating isn't too low. USB should be 5 volts anyways. The big issue with amperage, can the charger handle the draw? Example would be a 3000watt car amp drawing power from a 18 gauge speaker wire. It might work but the wire will heat up since it isn't designed to carry that much current.
In short for USB the charger amperage can be higher than the device needs but probably no less than 1/2 the rated amps for the device.
As above, you could plug in a 200A charger and the phone will still only draw the same current as from a 2A charger.
The amount of current drawn by the device is firmware controlled to protect the battery from heat damage.
The stock charger is 1.5A so the phone must draw no more than that.
It's all about cables too. I have a 2 amp TomTom charger hooked up to a 3 metre long USB cable but it charges slower than the standard 'in the box' charger Sony supply at 1.5 amp.
More cable and wrong core rating = more energy lost or wasted. I actually had to ask a sparky about this one, but it's true. Cable length, rating and core make all the difference.
For instance.
If you hooked up a 3 amp charger (I had one for an old phone) to a cable that can only handle 1 amp then you will only get 1 amp into the device, probably melt your cable too over time.
Honestly, the best bet is to use as near as dammit to the original rating on the included in the box charger. Electricity is a funny thing, it can screw your phone up in ways only time and noting the battery life will show.

Hi everyone.
I recently got the Xperia Z and noticed the original charger packs a 1500mAh speed (which got me confused because I thought AMP referred to charging speed), but anyhow. I also bought a power bank (external backup battery) and the thing has 2 ports, 5V 1AMP and another 5V 2.1AMP. So I was wondering if the Z can take the 2.1AMP speed without damaging the battery. What do you guys think?
Thanks.
You won't harm it instantly no. Over time, yes.
The battery lives better if you charge it slowly, I charge mine with 500mA when I go to bed. I'd use the 2ma if you were really rushed.
My Stock charger is 1800mA btw. (Dock)
The phone will automatically limit the charging current (amperage), so the battery won't be charged too fast even if you use a 2A charger. I do not know at what amperage the XZ limits the current, but I suppose it's somewhere around the 1500mA of the standard charger.
On the other hand, charging with very low currents may also damage the battery. I read somewhere that prolonged use of a charger with less capacity than around 0.5c (c=the capacity of the battery; 2330mA) might be bad for the battery. Therefore it isn't recommended to only use the USB port of your computer (500mA).
So, for repeated use over long periods of time, a charger with a capacity of over 1165mA (0.5c) is recommended.
Well I don't know what to believe anymore :x
You can safely charge with almost any trusted-brand MicroUSB charger. As long as it's not broken or a cheap chinese knock-off or anything like that. It will output only as much as the phone will accept.
EDIT: 2.1AMP (as you state it) is 2100mA (milliamperes). That's it's current output. It does not refer to "speed" per se, but a battery will charge faster with a higher output charger. A 1000mAh battery will charge from 0 to 100% in one hour if you use a 1000mA charger. Or in half an hour with a 2000mA charger. That's the theory.
In reality, phones and batteries will have safety circuits that limit the charging current so that the battery won't get damaged. It simply will not charge faster than what's safe. If, say, our XZ is limited at 1500mA, then it won't let in more than 1500mA. No matter if the charger is rated at 1500mA or 2000mA. The phone will, however, accept less than 1500mA, but when the current sinks below a certain limit, the phone won't charge at all. That lower limit might be somewhere around 400mA. If your computer's USB port gives out considerably less than 500mA (which is the norm), then there might be something wrong with the port and the phone won't accept it.
For comparison, the Samsung Galaxy S II won't charge at any higher than 700mA. No matter if you connect it to a 700mA or a 2000mA charger, it will only take 700mA and that's it. The stock SGSII wall charger is 750mA.
The XZ, having a bigger battery, will charge at higher than that. I'm guessing 1400-1500mA because the stock charger is 1500mA.

Awesome then, thanks a lot for your help
Let's face it. It's always best to go with the original charger. If you use a non standard charger the best practise is to use one that has a similar amperage. That said, my Power Bank case puts out 1amp via the dock pins, so... And it's made for the Xperia.

Hi! I bought a wall charger from Aukey that allow to charge up to 3 devices at the same time, what is great since I'll be able to charge the phone and the tablet at the same time! According to the manufacturer the charger is able to adapt the output to the needs of the devices! So my question is, can I use this charger to charge the GWR without damage the watch, since the output of the original charger is only 0.85A!
I think it should be fine. I have used my charger a couple of times without issue for my GWR and now my Huawei

It is completely fine. The charging circuits of these devices (watches, phones, tablets etc) takes only what it is allowed by the limitations set to the charging IC circuit when supplied with 5v power over USB. I have an USB amp meter and the GWR barely uses half of the original chargers 0.85a capability. I've used my OnePlus One charger (a high quality 2A charger) to charge my watch as well occasionally, which also charges my Nexus 7 2013 regularly and that never takes more than 1A~ from this as well.
I've been using a Aukey Charger for a couple of months and no problem so far. The current regulation is supposed to be made by the device, not by the charger anyway ...
For those who wonder, I also checked if our G Watch R has QC 2.0, but it doesn't. It still charges at 5V on a QC 2.0 slot.
