[Xiaomi Redmi Note 3 [Snapdragon] ROMs, Kernels, Re] cat4443:
Well I did complete my intensive research as well as my own experiments... So here are my results regarding QC on Snapdragon.. and Franco kernel...

First of all the kernel do support QC 2.0 (? I know we all know that but still for noobs)

Now most important RN3 PRO also support QC 2.0 the circuit, the processor and the battery do support QC 2.0

(It's a 100% confirmed fact)

But the charger and the software does not...

So some tweaking enables it ... Definitely Yes!!!

But as every coin has 2 sides.. This too has..

Read on what I did to come to this conclusion..

Well I went out in the market bought couple of quick chargers ...2 quick chargers borrowed ( I know I don't have to mention it but I have to write something ??...Please tolerate me) ...

Well these were

1) One Plus dash charger

2) Pixel XL fast charger

3)Moto G5 plus turbo charger

4)Le Eco Le Pro 3 quick charger

The test conditions were

AC on for an hour at 24℃... The room temperature was 23℃ .. I am on Pure Nexus .. All apps were closed.. Data wifi auto rotation...Sync.. Location Bluetooth etc..All off

The device temperature was 32℃ and I had a sponge soaked lightly in water....

I made sure the temperature was not high as high temperature causes the quick charging go off so that your phone don't become GALAXY S7 (?? I find this line funny)...

Now I did use all the chargers 1 by 1 and the phone was started charging from 3%

1st- The One Plus charger

It took me exactly 2hr 23min to charge that thing with a dash charger (I know it's USB TYPE C I just slashed the end and attached a normal cable...I think that might change the rate..) now I had a check on voltage and the phone started with 3.6V and then rapidly It went up to 5V in just span of 4mins !!!!! But then after 20 mins again back to 4.0V and at this moment the temperature was 45℃......

2nd - Pixel XL charger

It took me exactly 2hr 12min to charge from 3% to 100%

Now this time the phone started from 3.8V and went up to 4.6V in just 4min.. and after 15mins it went to 8V....And after 23min It was on 11V.. Interestingly temperature was at 41℃ ... But then after 28min the rate went down to 3.9V!!! (I thought it would have went to 100 in 1hr 50mins..But ....No)

3rd-Moto G5 plus turbo charger

Well this time I didn't expect good results but I was shocked..

Well the phone went from 3% to 100% in 2hr 18min!!!! Wow...

It started with 3.8V and raced up to 4.4V in 6mins

Then 7V in 26mins and full 12V in 34mins ... but this time the temperature was 47℃ and again the rate slowed down..I had to turn the charger off as I don't like a GALAXY S7 (?????)

4th- Final Le Pro 3

I expected some good results and the results were really pleasing this time I used a converter

It went from 3% to 100% in 1hr 58mins !!!!!!! Well I don't know how the rate started from 3.9V then 4.2V in mins then 5.2V in 17mims then 9.6V in 26min and 12V in 34min and this 12V was constant form around 8mins!!! Well this time I cheated ...I reduced AC to 20℃ soaked the sponge with chilled water and place the phone between Ice bags (I took care guys .I didnt place the phone touching the ice bags ?? I have some sense)

Well the temperature of phone was 45℃ ...But rate never reduced

Disclaimer- I didnt use and voltmeter....It was Pure Nexus stock charging info... And the time results are genuine...I did use a stopwatch and the times mention are completely original.. Apologies if I gave some wrong info with half knowledge..overall the kernel is great it took very heavy usage to reduce the charge to 3%... The phone do support QC but It's not good for the health of that beast....I mean 45℃+ is not a comfortable rate and moreover the rate was never steady as temperature matters... So I think it comes in handy at times but I prefer stock charger

One more thing the QC sign in MIUI beta version is true ...It is QC sign as per MIUI moderators...But they say it don't support stock charging though the symbol appears...If you need some more assistance am here.

Cya.. Chao ?
