I've just bought an ipad.
I've tried the usb cable with that supply and the phone seems to be charging. Given that the ipad supply is 10w instead of the 5 of the defy, will it charge faster or will just burn it?

As an answer to my own question, it's been a week since I'm regularly using the ipad charger with the defy. I haven't noticed any drawbacks. No overheating, no screen oversensitivity. It even seems to charge a little faster.

You can charge. It is the voltage that must match (and for USB it is standard and equal 5V) And the wattage of the supply(charger) should be greater or equal to the device's wattage.

i don't know about that. i just plugged in a 22,000 watt 5V supply. the phone exploded, blew out two windows of my house and the battery is still lodged in my ass. do you think i need to go to the ER?
If I use the power supply from HTC the touchscreen's response is bad. Drawing gestures on my lock screen doesn't work good. But I'm using if for over a year now, and had no problems. Guess it could be worse for my battery.
Shouldn't be too hard!
You should be able to use the iPad power block with and USB cable... That's my understanding.

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.

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
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.

I've googled it and I'm getting very mixed opinions. Most say 2.1 of course is faster for charging. I am led to believe that because even the box to there car chargers say the same.
I would like to disagree but need help understanding why. Maybe I'm wrong and I have a faulty charger.
My charger has two ports. One is 1amp and the other is 2.1amp. My 1amp side seems to actually charge my phone faster than the 2.1amp side. Also with 2.1amp while in listening to music through Bluetooth using GPS and navigation all at the same time, it tells me my phone is dying faster than it's able to charge. With the 1amp side I'm able to hold a steady charge sometimes going up at least 2 percent during a 30 minute drive.
What's your opinions? This isn't the iPhone or Samsung threads so I'm sure we have some of the smartest guys/girls here on xda
Edit: sorry I'm a bit stoned atm so forgive me for my typos and I'll fix tomorrow.
.....don't judge. I live in Washington state. It's just as legal as buying a bottle of beer.

Ok sober now. So nobody knows why 1amp charges faster on this phone than a 2.1amp car charger? I've used several car chargers and it's the same issue.

It should be a no brainer that a 2 amp charger will charge your phone faster as opposed to a 1 amp simply because one has more output than the other. But I believe that because of the smaller battery the phones have, they need a smaller amp per second of charge. If not then it may destabilize your battery.
Thats just my two cents though. Dont quote me

Be careful with those 2 A chargers. I have seen a lot of threads with fried Ones because of chargers lately

HTC put a limit on how fast the phone can charge. The chipset supports rapid charging but at what cost (of the battery)? So to be safe HTC disabled that feature of the chipset. So even if you plugged it into a 4 amp USB connector, you are not going charge any faster than say 1 amp. Don't know what the specifications are on the optimal amperage...

Using a higher amp charger cannot damage the battery. The phone will only pull as many amps from the charger as it needs (probably 1.5 amps max).

could you possibly link to those threads? I have the dual charger 1&2.1. My results are opposite of op my 1a doesn't charge phone but the 2.1 gains charge while driving even while watching movie! id like to read up if it may be problematic! thx
Htc one battery originally is charged by 5V and 1A charger; Can 5v. and 1.3 A damage the phone?
One thing that nobody here has mentioned is the possibility that your charger might have been wired wrong and the side that charges faster is actually the 2.1mah connection instead of 1mah.
With all of the chargers from everywhere in the world that we get them from and they are supplied from, anything can happen that We don't expect.
Maybe you might want to get it tested with an OHM Meter to verify which connector is the Higher and which is the Lower.

The only thing that is different (as far as the phone is concerned) is whether it sees an AC style charger or DC style. No matter what, the phone will only pull what the charging circuit "says" to pull.

For some chargers, sometimes the 2 Amp port appears to be using the Apple protocol for USB power, so that port will only provide 0.5 Amps to most other devices. And when the1 Amp port somewhat over delivers, and can source 2 Amps if nothing else is connected and 1.5 Amps if the 2 Amp port is sourcing 0.5 Amps for a non-Apple device. Thus some chargers can support one high power non-Apple device (in the 1 Amp port) and one lower power device (in the 2 Amp port). FYI I use this charger bought on Amazon---Avantek. Worked really well, versatile and low profile.
