Hi,
Has anyone tried to charge the Note 3 with a Qualcomm Quick Charge 2.0 charger and does it charge significantly faster?
The reason I ask is that our phone's processor, Snapdragon 800, is listed as supporting Qualcomm Quick Charge 2.0:
https://www.qualcomm.com/products/snapdragon/processors/800
The technology works by ramping up the charging voltage when the battery is low, and slowly reducing voltage as the battery fills up.
This is exactly the same technology which the Note 4 uses and dubs "Adaptive Fast Charging".
The latest Qualcomm Quick Charge 2.0 chargers charge at:
12V * 1.5A = 18W
9V * 2A = 18W
5V * 2A = 10W
(voltage is reduced as battery charges up).
You can see the voltage/amperage of the charger written somewhere on the charger.
Chargers that are 5V/2A only (e.g. stock charger) are not quick charge 2.0.
This is not to be confused with USB 3.0 charging (which is only ~5V * 1A = 5W from PC), or 2A chargers (5V * 2A = 10W from 0 to 100%).
Our Note 3's chipset supports this, but it won't be very surprising if Samsung disables this on the firmware or kernel level.
If anyone has tried charging the Note 3 with a QC 2.0 charger, your input is much appreciated!
I haven't used that charger, but I've been charging at nothing but 2A for quite some time (via kernel settings). It seems like it charges up pretty damn fast, and I haven't noticed any ill-effects from it....
Note 4 charged with quick charge, discharges faster too, so I think it's useless if the battery life decreases.
Maybe it's a problem of the note 4, but I don't think so.

It charges at double speed at <80% (or similar, varies depending on when it throttles to 5W/2A).
Essentially, you can charge up to 60-80% within half hour, as advertised by Qualcomm.
That's extremely useful if you simply want to add 30% to your battery life with 15 minutes of charging before leaving the house, etc.
The difference is more obvious with half hour: 50-60% charge versus 20-30%.
Hi, to which kernel are you referring to old ? Some chancethat it is vcompatible with stock Lollipop ? Thanks
Checked with a multimeter, maximum I can reach is 5V on a Note 4 charger even I am charging from 10% and screen off
Samsung disabled this. Didn't try on 5.0 anyway.

To my knowledge, the Note 4 charger is not a Qualcomm Quick Charge 2.0 charger.
It is a Samsung-proprietary variant for the Note 4 only, and unlike other QC 2.0 chargers only toggles between 5/9V instead of 5/9/12V.
Note 4 however does support the Quick Charge 2.0 standard as well.
Please do correct me if I'm mistaken.

If I remeber well the stock charger from Note 4 has 9V/1.5A and 5V/2A

Yep, but the Note 4 charger's adaptive charging is proprietary and restricted to Samsung's Note 4 - it's not a Quick Charge 2.0 charger AFAIK.
Anyone actually tried charging the Note 3 with a Quick Charge 2.0 charger?
e.g. http://www.amazon.com/Tenergy-Unive...d=1421031846&sr=8-1&keywords=quick+charge+2.0
No, but a friend in work has a note 4, I will test tomorrow an post back.
Any specifics you want testing, results with various apps etc?
I don't think so that is supported, but some1 got to try it...

Fast Adaptive charger comes with galaxy s6 i tried this charger on my note 3 but fast charging is not work on note 3 and this charger is intelligent itself to deliver required amount of current to mobile my phone charged simple on 1200mAh to 1800mAh regular current delivered to Note 3 by Fast Adaptive charger when i put it on s6 it automatically detect it and on fast adaptive chrging it gives 9V ,1.97A to maintain high speed charging but not on Note 3
boomWow!
Years later, I've tried my Nexus 6's FastCharge 2.0 AC adapter and it charges significantly faster.
Doesn't charge any faster on stock firmware, checked using ampere , charges at the normal 1200mah with screen on which I believe is the max with the screen on surely there is someway to unlock it
yes it supports you can buy Tech Sense Lab 3.4 Amp Dual USB Car Charger
The ampere app shows my Note 3 charge at a 1.8A from normal 1.2A steady flow, this is with Qualcomm 2.0 QCharge... It is probably the max rate for the device.. It is fast, especially within the lower band of the battery capacity.
With Qualcomm QuickCharge 2.0 the voltage does not ramp down, only the current does. The whole point of QC is to overcome the resistance inherent in many micro-USB cables, and that's done by boosting the voltage. My Note 4 charges at 5V/1.7(ish) amps on a non-QC charger, and 9.4V at the same current on a QC 2.0 charger, and that voltage is maintained throughout the charge with the current ramping down.
My girlfriend's Note 3 does not charge at increased voltage on my QC 2.0 charger. It just does 5V charging.
Measurements were made at the output of the charger with a USB digital multimeter.

I haven't had any problems with battery life on my Note 4, and I quick charge mine frequently. Must be a problem with YOUR Note 4.
My adapter is 9v 2a and i can say it charger significately faster. Alot faster.
Stock charger takes anywhere between 3-6 hours where as mine takes 2-3 hours max.
I have got a replacement battery(chinese one) but is equivalent to the stock samsung battery.
Also i am using a ported rom from the s7 edge so fast charging could possibly be enabled within the kernel especially if the cpu supports it

Any suggestions? I'm looking for something that can do the quick charging in the car, is that even possible? Can it be done with a dual port so my wife and I can use the quick charger at the same time?
http://www.amazon.com/Charger-PowerIQ-Technology-Samsung-Motorola/dp/B00M43S18Y/ - Would this one support quick charging in the car?
Also,
http://www.amazon.com/Anker®-Extra-Premium-Android-Samsung/dp/B00NPP7TVU
This is basically the same cable that came with my S6 just longer correct? The included cable is too short to plug in near my night stand.
Any charger that is a 2amp charger... and any cable.. i have tried all my old cables on the s6 charger... all allow fast charge... and its charger is 2amp.... same as nexus 7 and all other newer devices... so just go with a 2 amp charger and enjoy the fast charge. And yes they make dual port 2 amp chargers... usually 1 port is 2 amp and second one is like 1 or 1.4amp... i have 2 cheap ones from amazon myself... will test them with the phone tomorrow and update you.

any cable will work, but not every 2.0A charger will work. i tested it with a 2.0A (not the Samsung one) charger and "fast charging" did not show up in the phone.
AFAIK, you have to use one of Samsung's OEM chargers or one capable of the Quick Charge 2.0 standard for adaptive fast charging.
OP, i only did a cursory search, but i found this dual Quick Charge 2.0 charger that might meet your needs: http://www.amazon.com/dp/B00TGD79X8?psc=1
Interesting, I didn't think to check for QC 2.0. I was thinking the Anker one did that. Thanks!
That being said though, anyone have experience with any of them with how they hold up?
Verizon sells one, it is their generic branding, it's the only one that I have seen or tried that is marketed that it is QC 2.0, works great even has a built in LED flash light basically. Sucks that it is $34.99 though.

From my understanding Quick Charge 2.0 is a Qualcomm Snapdragon 801 (or newer) processor feature. The Galaxy S6 is running Samsung's Exynos 7420 processor which features Adaptive Fast Charging. I don't know how they vary in terms of performance, but I do know that when I plug in my Quick Charge 2.0, my S6 recognizes it as a fast charger. Battery went from 40% to 63% in 13 mins so I'm assuming both charging standards are compatible lol..
Try this car charger, worked great for my Qualcomm based phones.

i'm reasonably sure it's the same standard. the Note 4 (Snapdragon 805) is listed on Qualcolm's website as compatible with QC 2.0. however, if you look at Samsung's website, it only lists Adaptive Fast Charging. Samsung just rebranded QC 2.0 as their own Adaptive Fast Charging. you can use all devices interchangeably.
also, the OP wanted a dual port QC 2.0 charger. that one only has 1 port w/ QC 2.0
I have already Anker 2 amp car charger in hand and i was thinking it wont be fast enough , i have seen video where quaclom demonstrated that Quick charging is faster than 2 amps charging , and judging by the fact that Samsung is providing comparable charging time with stock charger i was thinking that it is more than 5V 2.0 Amps .. too bad i am waiting for my phone to arrive.

I just purchased this.
I purchased this one from amazon when I had my Note 4 and I can confirm it works great with the S6. http://www.amazon.com/gp/product/B00P9UILUM/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1

Yep. Your right sir. Just tried all my 2.0 / 2.1 amp chargers... not quick charging... guess ill grab some qc 2.0 amp chargers from amazon for car and backups.

This is the one I was looking at, thanks!
Recently bought a Choe 15W fast charger and when i use it, the battery recharges at 2.5A which is significantly faster compared to my samsung charger at 1.5A. I also read that quick charge 2.0 should not let the current to increase above 2A. Is this normal? The temperature is also higher at 44 degrees celsius compared to 41. I thought E8 should have quick charge 2.0 implemented based on gsmarena.
quick charge 2 works at 9V/1.67A
its not about the amps only
it means your charger is not quick charge 2.0
dont use it
Hey guys I just wanted to know that if our device supports quick charge 2.0.? Because Qualcomm says that our processer supports quick charge 2.0.? If it does where can I get a quick charge 2.0 charger? ?
Thanks in advance

I'm just taking a wild guess, the stock Mi charger is QuickCharge 2.0 certified...
Nope, NO Quick Charge 2.0 . Our phone sports quick charge 1.0. Well i get a full battery in 2hrs and 12min . But Phones with quick charge 2.0 charge very fast i have seen nexus 6p charge in 1hr!
probably we need to use latest caf .....
Hi, the unit comes with just a basic 1a charger, i saw in qualcomm's website that snapdragon 450 supports quick charge 3.0, i was wondering will a charger with quick charge 3.0 work for me or it will only be a waste of money?
