Why is it that the sprint car charger charges the phone 3 times faster then any other charger.
I tried 4 other different chargers that put out 1A to 2A and charges the phone really slow and when I'm using it while it's charging it either stays or goes little below the battery level of what it was when I plug it in, then I tried the sprint charger and it charges the phone allot quicker and also will charge when using it while plugged in unlike the other chargers.

when the usb cable connect to my laptop is charging my xt860 without any problem.
but in my car it's not (with the iphone it's charging perfectly)
any idea?
Whatever car charger your using is not supplying enough power to charge the phone. A lot lf laptops will have a continuous 5v (just enough to chage the phone). But the car charger prob only puts out 4v and the iphone is alright with that (charge really slow) but the phone is picky (won't charge at all). All I can say is try another car charger.

thanks i will buy a new one
I grabbed a Motorola brand one off Amazon for $5 and have never had an issue. But any brand name microusb car charger should work as long as it puts out enough current.
Just found out that the LG USB wall outlet has a output of 5V or 1.2 amps while my apple and samsung USB wall outlet of 5V or 1.0amps
The regular wall charger for my sg2 had a output of 5V or 0.7 amps
Figure i give a heads up to those who wants to have a shorter charge time.
I got a 2a USB charger that I have always used for this reason sure in wont get the 2a but will at least get max that I can

The charge rate is fixed by the phone. You could have a 100A charger and the battery would still charge at 900mA (in the case of the SGS3 and Nexus 4). The charge rate from USB remains at 450mA

So if you use a 5V / .7 amps charger for the Nexus it should be OK right?

Yes, it will just charge slightly slower.
Does using a 5V 2a charger damage the phone's battery?

No. It's better to use a stronger charger than a weaker one. The phone will only drain as much as it needs.
If you guys have a N7 you can only carry the N7 charger as it will charge both devices as fast as they technically can charge.
Does anyone know why the One might behave differently on a car USB charger compared to a Galaxy S3?
I noticed my One was charging slowly or not at all when in the car. Using the power stat screen in the SystemPanelLite free version it shows the One is only connected at USB charge power, not "AC" power. However if I plug this same cable into my old Galaxy S3 it shows in SystemPanelLite that it is charging at full AC speed. I tried both the One and S3 default charging cables, no difference.
I'm using a car charger rated to put out enough amps for full speed charging, and it works great with the S3. With my One I tested it just plugging it into the charger that came with it (AC outlet, not in the car) and only then do I get full AC charging speed.
Anyone have ideas on how to get full AC charging speed on the One in the car? Any suggested car chargers confirmed to charge at full speed?
quick charge is disabled. you also need to make sure the charger is at least 1A @ 5V.
On previous HTC phones, I'm led to believe that the data pins on the USB connection are shorted inside the charger, and that's how it detects AC vs USB. It's not AC arriving at the phone of course, in reality it's 5VDC, with "AC" it draws 1A vs 0.5A for USB.
If the USB cable is not wired appropriately, the HTC One will slow charge so that it doesn't draw more than the USB standard 500 mA. Your charger needs to be wired accordingly so that the HTC One knows that the charger is capable of supplying more current, otherwise the device won't pull the extra current to fast charge. See http://forum.xda-developers.com/showthread.php?t=844284 for details.
Benpope and rumball have correctly answered.

Will this charger work with the HTC One @ 1A? http://shopamerica.htc.com/product/productpop.htm?prId=41645
Well at this point I'm looking for anyone who can confirm they have a car charger/cable combo working with the One that will charge at or near 1 amp.
I don't think my cable is at fault since I've tried multiple ones, including the AC one that came with the One.
Although my current car charger worked great with my GS3, I guess the One is more picky. So can anyone recommend one that will definitely do 1 amp with the One?
the data function on the car kit cable doesnt work as well...plugged into computer and charges but nothing else (to bad to, liked the length of the cord)

This is right, I had same issues with s3, resolved by buying a genuine Samsung charger. Before my Google maps drained more than it could charge. What's odd is that the s3 charges fine on his cable, unless different pins are shorted on an htc?

Have you used it and confirmed it charges the One at "AC" speeds?
Hi, im just wondering is there any benefit using a 2amp charger on the htc m8 , faster charging ? i know HTC are gonna release a faster charger which is 1.67amp , is it just the amp or it has some feature Quick Charge 2.0 built in you cant get with other chargers ?
the HTC One is rated to support Quick Charge 2.0 capable of accepting up to 60 watts of power – an increase of almost 100% compared to phones with Quick Charge 1.0. The 1.5amp charger bundled with the HTC One (M8), however, does not support Quick Charge 2.0. HTC is planning on releasing an optional 1.67amp charger accessory that will come with the technology later this year
Thanks
Yeah, it will charge a bit faster.

I've used the 2.0A charger that came with my Galaxy S4 and didn't really notice the phone heating up to unusual temps.
You can use a 10A charger if you have one (and it works with your power outlet), the phone should never draw more than the maximum it draws.

I originally used the charger I got with my M8, but then switched to a 2.5amp charger. According to GSam, my time to charge from around 80% to full is around 15 mins, but with the original charger, it was around 30 mins.
So from my experience, it does charge faster. From what I have read about QC2, the technology is in the processor in the phone. The charger can be any type, as long as it is able to deliver up to 60 watts.
See here - http://www.zdnet.com/qualcomms-quick-charge-2-0-offers-75-percent-faster-charging-7000026519/
The tech is actually in both the phone AND the wall charger:
From http://www.qualcomm.com/chipsets/quick-charge
"While Quick Charge 1.0 rests in the devices only, Quick Charge 2.0 resides in both the device, offered as a standalone IC solution or as part of the PMIC (power management integrated circuit) of Snapdragon™ 800 processors, and in the AC/DC wall charger."
The one you link is worded a little ambiguously:
"Qualcomm hopes to take things further by integrating Quick Charge 2.0 technology into standard micro-USB AC/DC wall chargers. These chargers will look and work like standard chargers, but will be able to deliver Quick Charge to compatible devices."
I tripped on it a couple times when reading it too, but it's implying that the tech does not currently reside in standard chargers, since they're still working on integrating it.
guess i will get the HTC fast charger when out and i bet we should get compatible quick charge 2.0 chargers too
Thanks
The amperage of the charger makes no difference, the device will only ever draw the power it requires to charge, no more. so a 5a charger would be no different to a 2a charger if the phone only draws 1.5a for example. find out what the device needs to charge and get as close as you can to that size for protection reasons

Yes, it will charge it faster. I used my 2amp charger and it did charge it faster. The phone may have some protection built in to protect the phones hardware. But the battery can handle much higher charge rates and the battery shouldn't start heating up till 20-30 amps. Yes, that's right.
I use Li-poly to race electric RC's and we charge them up to 50 amps. This charger will --->http://www.hobbyking.com/hobbyking/store/__46368__iCharger_308DUO_1300W_Dual_Channel_8s_Balance_Charger.html
Most people only charge at 5-10 amps, but to get peak performance, you will need to create a bit of heat and that doesn't happen till 20-30 amps.
Since I jumped from my old note 3tothe m8 I was able to keep the charger and it's a 2A one. Will I get the full 2.0 benefits with it or must I wait for the HTC one?

You will get whatever amp the M8 can take. i assume its 2A
I have a 2amp charger and i use it for my M8. i only see about a 30 min different from using a 1amp charger.
Its not just Amps, quickcharge 2.0 Also bumps up voltage. I tested multiple combinations with my htc one M8, here are my findings:
Quickcharge 2.0 18W Aukey (with regular micro usb cable): 9v/1.1A (~10w)
Quickcharge 2.0 18W Aukey (with data cut off cable): 5v/1.52A (~7.5w)
Wall 5v 2.4A charger: 5v/1.52A (~7.5w)
Stock 5v 1A charger: 5v/0.99A (~5w)
Car 5v 2A charger: 5v/1.3A (~6.5w)
some old 5v 700mA charger: 5v/0.7A (~3.5w)
MacBook Air USB port (2013) (with regular micro usb cable): 5v/500mA (~2.5w)
MacBook Air USB port (2013)(with data cut off cable): 5v/1A (~5w)
Ipad charger rated 5.2V/2.3A : 5v/1A (~5w) (no clue why its so sucky)
Also I noticed m8 once connected to charger (non Quickcharge 2.0) slowly increases charge current. if voltage drops below 4.92v it drops it back to these fixed values, whichever is immediate lower: 3oomA, 500mA, 700mA, 1A, 1.3A, 1.42A. 1.52A
these values are as per multimeters.
my car charger is tricky, it sometimes just falls to 1A instead of 1.3 as it border lines V to 4.92 while at 1.3Amps. (it is rated for 2.4A)

Hi. This was asked before, try searching.
One thing I've noticed when I had the stock rom on my Note was the insane amount of power the Note took, the bad charging cable, and stock charger. Never was able to charge it while it was on. I ended up getting a heavy duty charge cable and a 1 Amp (1,000 mAH) charger. Charges much better now.
