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

Mi4i features fast charging. Can you suggest a better charger than 5v-2a charger?
Apple iPhone charger shows up as a fast charger for me.
fast charging is supported but the charger in the box is a normal one. (5v2a)
can anyone try out with the proper fastcharge2.0? (9v1.2a)
Donnt have one...would definitely love to get the feedback from someone who tested it first hand!
how do you see it 'shows up' as a fast charger?
are there any indication?
Mi4i FAQ http://en.miui.com/thread-122548-1-1.html
50. Does my Mi4i have Quick Charge feature? If yes, then which version does it support?
A: The Mi4i has Quick Charge 1.0, which explains the slow charging rate some users have been complaining about. The Mi4i takes roughly 2 hours 30 minutes to fully charge for me

And FYI, http://www.gsmarena.com/charge_test-review-1239p2.php
Quick Charge 1.0 was introduced in 2012 and it made use of a 5V/2A charger, which could charge a phone up to 40% faster than conventional 5V, 1A chargers. That boost accounts for a 10W max charging power.

Thus the original 2A charger that comes with phone is the fastest charger supported.

Xiaomi Mi 4c Charging Analysis Part-2
I just bought Tronsmart TS-WC1Q and I must confirm almost the same results as with original Xiaomi charger for Mi4i. Charging current with Tronsmart charger is about 1,44A and voltage is stable about 5,2V. I'm not sure, if I can determine from these results, if its support QC 1.0 or 2.0. Next time I will try to measure the time from 0->40% of battery and compare original and Tronsmart charger. Anyway I think it matters also on the ROM/kernel you are currently using. I'm on RESURRECTION REMIX with Sensei kernel v1.3.2-dev kernel.
I m on cm13, it looks like qc2.0 is supported. I used a China charger (9v1.2a). It charged fully charged up from 0 to 100% in 1hr and 40 min.
i have tried
i have tried qualcomm's fast charging 2 it works well.
How fast is Mi 4i supposed to be? I've bought orico quick charger 2.0 and it does about 1.5 hr to be fully charged. Do I need to install something to make it faster?
I wonder if the Samsung Car charger Fast Adaptive which is the name sammy gave for Quick Charging 2.0 is compatible with the M9?
The wall charger version work from what I heard but dunno about the Car one
Maybe the output specs could shed some light on interoperability. I'd guess that between the differences of Samsung's Exnos processor and Qualcomm's Snapdragon there isn't much collaboration to build a common fast charging standard. Too bad, that.

General properties of batteries. Fast charge and discharge cycles cause them to break down sooner.
Guys, I tested the Samsung Adaptive Fast Charger and it was a no-go. I tried two different ones under ideal charging conditions and what I found was the charger would sync with the phone and boost to rapid charge levels, but it wouldn't sustain them. It kept prematurely stepping back down to slow-speed, lower amperage levels. So IMHO you should save your $$.
The QC2.0 certified chargers that I have found work 100% are the ZeroLemon wall charger and the PureGear 12v car charger. Both will lock the phone on at high rates of charging unless (or until) the phone heats up too much, then charging is throttled until the phone cools down some. My observations are that it will definitely throttle after temps rise above 100F and if you cool the phone down by (e.g.) holding it in front of the A/C vent, rapid charging resumes.
Ok so I tested the Samsung Fast Adaptive Car charger and it's pretty fast even with the screen ON due to the Car App, though better let the screen dim by itself or the phone will get hot.
Conclusion: I recommend this charger even though it's a little bit more expensive than Chinese cheap QC 2.0 that can end up DOA or be bad for your battery
My wall QC 2.0 charger works as it should once over 3 and the screen can be a little weird
It only says Huawei quick charge in the charger. I was wondering if an external battery with qualcoms quickcharge 3.0 will charge just like the huawei's wall adapter
Correct me someone if I am wrong
But this is not qualcomm or snapdragon
This is an Huawei entirely made by Huaweis technologies like the HiSilicon and Kirin
Thats why it only says Huawei quick charge
And external battery will depend how you charge it
But I think it should only work with qualcomm and not Huawei

Correct, not Qualcomm QuickCharge technology, but proprietary Huawei quick charge.
Anker makes some good 'auto sensing' chargers that will charge the H8 pretty darn quick, however.

The Honor phones are not Qualcomm Quick Charge compatible. The Huawei Quick Charger that comes with the phone supports both Huawei Quick Charge and Qualcomm Quick Charge 2 according to its specs. So if you have an external battery that supports Qualcomm Quick Charge 3.0, you won't get the 3.0 speed from Huawei's charger, but it probably is quite fast (since I would assume your external battery also accepts Qualcomm Quick Charge 2).
Anker and Tronsmart QC3.0 and other proprietary fast charge speed up H8 charging, opposed to standard 2A chargers. Seem a bit slower than original charger but not by far.
Huawei uses their own fast charger.
OnePlus do the same.
When you already in this situation just try it out a d you will see how fast it will be.. and then let us know how it went.. maybe you will help someone.. I would also like to know if it will fast charge and if how fast
Any Qualcomm Quick Charger (1.0, 2.0, 3.0) will recognize that the Honor 8 is not compatible and will default back to the maximum amperage the phone's internal circuitry will allow. Not sure if it's 2A, 2.1A or what... but it basically doesn't matter what the charger is capable of if it's NOT a Huawei Fast Charger. It's speed will be dictated by the phone. Huawei's Fast Charger is the only charger that can get you the fastest charging speed on the Honor 8 and does so without heating up your device, which is the safest way to fast charge.
Huawei Fast Chargers can be found on eBay all day long for $10. There's very little reason to buy anything else since it too can charge Qualcomm QC phones and batteries.
I've tried charging mine with Aukey PB-T10 powerbank, which supports QC 3.0 (but not Huawei FCP). To my surprise, the phone shows "Fast Charging". Similar power draw between original charger and this one (9V, 1.2-1.4A), based on USB Doctor. And similar charging time too.
I've also tried with a QC 2.0 charger and it's just normal charging.

Wow, thats nice. Can I have the link? Is it this one?
Yes. This is my personal finding and nowhere an official statement :fingers-crossed:
A good QC3.0 would give very similar charging times as the original charger. I've not been using the original one and use one QC3.0 at home and another at work and they're pretty dam fast.
They added qc4, but it's more like qc3 with just 18w(9v 2A). I hope a kernel mod will allow the phone to get 27w which will charge the phone completely in approx 1h 30m to 1h 40m rather than 2h 15m with the 18w charger.
Whatcha think nerds?
I think that's a bad idea as they will have specified a battery suitable for 18W charging ...
Battery should last for ages, anyway. It's 5000mAh, very close to pure AOSP, and the display is by no means large.
If you endlessly play with the camera motor, it might drain a bit faster, but otherwise, I suspect this will have the best battery life of any phone in the small flagship class.
I'm fine with QC3.0, since I've used that a lot.
But if it does come with QC4.0 then I couldn't be more happier.
With the battery capacity it has, I don't think I need to charge it all the time so QC3.0 is something extra for me.
The sustained speeds should be higher due to the battery size but I wouldn't personally want to risk modding the charging speed. Sounds like they made the insulation layers pretty small to get the capacity at the expense of charging rate.
My main concern is how well it sustains the speed and the temperatures (QC4 should be decent in that regard) because any maximum speed will drop off a cliff when it gets to 70-80% anyway.
Does it have 4.0 or 4.0+? I've seen some spec sheets saying it has 4.0+

It's really difficult to even find data on what the difference of those two are in real world scenarios. If I'm not mistaken the + version requires two PMICs (whereas it sounds like it was optional before) and I think the Zenfone might just have one. Asus themselves advertise 4 without the plus. If you ask me, Qualcomm should just have called it 5.0 to avoid the confusion especially because Qualcomm's own marketing material is very vague on this.

I'd be surprised if the battery didn't get dangerously hot if it's done.
The separator wall of cathode and anode on a battery that can handle faster quick charging would need to be thicker.
Asus chose 5000mAh with a smaller separator to keep size down. In the same size, ASUS could have chosen, like many others have, to have gone with a ~4000mAh battery with a thicker wall to support 30W+ fast charging.
It comes down to trade-offs based on physics. I'm always game for experiments though
Did a very little test. on org charger and cable
Battery on 65% did give 7,5 Volts and 1,65-1,70 Amps
Hello, today, I bought this phone and I plugged it into charger for the first time. However, in my opinion, the phone warms up relatively high compared to my previos samsung S8+. Have you got any experience whit this? Maybe I am too much perceptive and it's normal. And maybe it is the difference between Quick Charge 2.0 (s8+) vs Quick Charge 4.0 (asus)

The difference between quick charge 4.0 vs 4+ is that 4+ is compatible with USB PD (power delivery) which is the fastest charging standard, its what i think OnePlus and Samsung use for their tech. 4.0+ was revealed in 2017 a year after 4.0. It's lame but unfortunately Asus's zenfone 6 current batches do not support 4+ (however 4+ charging is still backwards compatible with 4, 3, and 2.0, that's why when @MishaalRahman tried their QC4+ 27W charger it didn't charge any faster, it just downgrades to 4.0 charging speed)
there's a chance a refresh of Asus's zenfone 6 may happen with 4+ release. Doubt it..but who knows
4.0 is still supposed to charge faster than 3.0 but I personally don't really see that increase in charge speed. Could be because of the size of the battery but either way I'm still happy with it because the large battery just means less charging (for me personally) since I just mostly do google searches and text, and once in a while use snapchat/ig. Its the perfect phone for me, I bought it yesterday to replace my Pixel XL (gen 1).
