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.

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

Next week getting a new Note 4 - and zerolemon 10,000mah battery!
I need to deep cycle battery 6-8 times to get phone to display the current vbbatt % correctly. The manufacturer for zerolemon says turn off fast charge and charge 12hrs each time.
That being said, with fast charge off, can I use a 5v 3.5 amp charger I see on amazon and possibly charge the phone faster than 12 hrs like normal is using a 2.1 amp charger?
Anyone tried this with let's say even the stock battery does the battery actually charge faster due to the increased amps or would it be a waste and still charges at the slower 2.1 amps?
I never deep cycled the battery and the longest discharge I got was 1 week with 16 hours on screen time...you just need to make sure you use an updated kernel with the zL fix.
The amperage rating is the max the charger can put out. The Note will draw the same amperage on either charger because they are both 5V.

But will the phone charge faster on 3.5 amps at 5v vs the 1.5 amp or 2.1 amp the stock charger puts out? I am getting ZeroLemon and need to deep cycle the battery a few times and am trying to have it fully charged in less than the standard 12 hrs - was hoping a charger with more amps would cut down on the 12 hrs lol
http://www.amazon.com/gp/product/B00WN86VYQ/ref=ox_sc_act_title_8?ie=UTF8&psc=1&smid=A3RPN0HBLXDN8Z
i just used the stock fast charger on my zerolemmon with fast charge on and i never let it go the full 1 hours. Ive had insane battery life with it so i dont think it matters

Your Note 4 will draw a maximum of 1.9A on a 5V standard charger and a maximum of 1.66A on a 9V Quickcharger. If you multiply these values, you will get your "charging speed" in Watts: The maximum is 9.5W on normal charger and 15W on a quick charger.
Using a higher rated normal charger (eg 5V/3A) will NOT INCREASE charging speed. The Note 4 will never draw more than 1.9A on 5V.
Using a lower rated normal charger (eg 5V/1A) WILL DECREASE the charging speed. The Note 4 will notice that it cannot get 1.9A from the charger and drop the current. Bad and/or long cables can also influence the charging speed negatively.
Also noteworthy: Quick charging will only work when screen is off. As soon as you turn your screen on, the charging speed when connected to a quick charger will drop from 15W to an extremely slow 5W. The only fix for this horrible Samsung joke is a custom ROM like CyanogenMod.
You can charge your Zerolemon battery nicely with the original Quickcharger that came with the phone. That will do 15W and is as fast as you can possibly charge.

Wow. Good info. Thx. Now a ton with a hack to draw more amps lol. Hmmmm lolol
Hi, i've just purchased Xiaomi mi 5 and i have question regarding charging the phone. It supports Qualcomm Quick Charge 3.0 however the charger that was provided only supports QC 2.0.
I notice that whenever i plugged the phone to the charger that supports Qualcomm Quick Charge, my phone gets hot. I decided to do a little test, so I used an USB Charger Doctor that can read voltage and Amp that it delivered to the phone. I've also using Ampere to monitor my battery temperature. I'm gonna charge for about 36 minutes using Aukey charger. It has 3 ports with only 1 that supports QC 2.0, the rest of the two supports up to 5 volts at 2.4 amps.
Here's the result:
9 volts, 1.35 amps = 56% battery charged from 8%. Battery temps reach 43,2 C. Juice added, 48%.
5 volts, 1.71 amps = 43% battery charged from 7%. Battery temps reach just about 35 C. Juice added 36%.
It's clear that qualcomm quick charge is faster than the standard port, however it resulting in higher temps. And i know the fact that Lithium batteries hate high temperature. So which is the best for battery life? Higher Voltage lesser Amps, or Lower Voltage Higher Amps? Thanks in advance.
Hello all,
I've recently ordered for my xperia z5 and z3 compact the following accessories for fast charging:
LG Fast-Charger MCS-H05ED
100-240V
50-60Hz
5V / 1.8A
+
Logilink CU0058 microUSB (USB 2.0 -- Max. Transfer Rate: 480 Mbit/s)
Does it replace the SONY UCH-10? Or is this better than UCH-20 at rapid charging?
I really hope I didn't messed up with this order, don't want any malfunctions on z5 - but original chargers weren't available in my country for same day delivery so I had to improvise based on tech specs.
it is only 1.8 A you need at least 2.1A to notice anything faster.
Look for a Qualcomm Quick Charge 2.0 (QC 2.0) certified charger.
@z5techno
You have to upgrade your charger. Fast charger not means higher ampere. Fast charger means higher WATT (ampere * voltage).
UCH-10 has 9v*1.700ma or 12v*1.250ma, 15.3WATT
You can use higher than this WATT, charger will adjust the max voltage and ampere that phone requires.
You can buy QC3.0 charger for future purpose, it can work with QC2.0 compatible phones. AUKEY and Blitzwolf are good choices.
Thank you for the detailed answer, @sceryavuz !
Until I upgrade to uch 10, I'll keep this LG charger - I'm pleased with this charging the phone.

Sony has locked maximum current at 1.5A so you won't notice the difference. With UCH20 I got 2h to charged my device, the time downs to 1.5h with UCH10 (QC2.0 supports). The result is same as UCH10 when I uses Anker PowerPort+ 18W 9V-2A (is my current adapter since it costs a half of UCH10 with better specs).

I use the iPad Adapter Charger for the Z5 and it gives me pretty fast charging speed
What is your S8 charging rate? (from 0% to 70%)
Mine is:
Fast charge adapter, fast charge on: 2.4A
Fast charge adapter, fast charge off: 1.6A
1A sony adapter: about 900mAh
Computer: About 500mAh
I tought "normal charge" with the fast adapter would use a lower rate. What do you think? I choose longevity (low current and low temp during charge, not going over 4.1v) over charge time, so i charge the phone to a max of 80% and at the lowest rate possible. I usually plug it in when i get home from work, and about bedtime is charged.
(My 3 year old Z1c still got 1 day battery until i broke the screen)
Fast charge adapter, fast charge on: 2.4A
Fast charge adapter, fast charge off: 1.6A

I think you mixed up your measurements.
Fast charge is 9V @ 1.67A (15W)
Standard charge is 5V @ 2A (10W)
