Charging time & is QuickCharge 2.0 supported?

Hi all,
I have read from several reviews that the Redmi Note 5 Pro supports QC2.0, just that it only ships with a 5V 2.1A charger.
Is it true that the RN5 Pro supports QC2.0? Also, how long does the phone take to fully charge with the included 5V 2.1A charger?
Planning to upgrade from my Redmi Note 4 as the battery life on this MTK model has been horrible, so any information is appreciated!
Thanks.

QC is officially supported for Redmi Note 5 Pro. QC2 is officially inbuilt however charger provided by Mi does not support QC hence you need to buy a additional charger to enjoy this feature.

Quick Charge 3 and 4 on Redmi Note 5 AI?

Is there any kernel in development for Quick Charge 3? And also, Wikipedia writes that 636 supports QC 4? so is there any chance later on we can get it? Modded?

Any chance of fast charging?

Qualcomm 3 Fast charger works as quick charger. When you see a lightning within a circle, it means quick charger works.

I think other part not support high voltage so not safe QC 3.0 and QC 4.0

The included charger is not quick charger, but I have one with Qualcomm 3.0 from different smartphone, that works.

Yeah. ANd it works in QC 2 . Not 3. there are many cideos in YouTube that test it out

Weird. I have LeEco Le pro 3 with Quick Charge 3.0, and it shows the circle with Lightning in it (in the status bar). That means Quick Charger works. By the way, I use non-stock USB cable, so I use Quick Charger 3.0 with better cable. I tried different cable with Quick Charger, it doesn't work.

Completely off topic, but im also using Pro 3, and thinking about buying redmi note 5. How do you compare phones? Which one feels better?

I like Redmi better, even it is slightly taller than Le pro 3, it has better (much better) camera, bigger screen and headphone jack but to play games, Le pro 3.
I have Le pro 3 Elite with 6gb ram and 64gb storage, but without SD-card, it feels "tiny" and since I download and flash different roms in it, it's getting full easily. It feels too powerful for me and cannot use its fully potential since the games, I play were casual games without demanding graphics.
Redmi has 3gb ram and 32gb (my device), but it has SD-card reader, so I can store roms and stuff in SD-card and use internal for most programs and games.
Le pro 3 has not updated it's rom since Android 6 or 7, but Redmi Note 5 has arrived with Oreo in it MIUI 9 and planning to upgrade to MIUI 10, but still in Oreo.

Redmi note 5 supports qc 3.0, I tested it myself. It can charge 0- 50 in 35 min with my qc3.0 power bank

There's two different variants one is limited to quickcharge 2.0 so even if you use a quickcharg 3.0 or 4.0 charger it still only gives you 2.0 speeds the second one can use quickcharge 3.0 speeds.

The specs the AI version has a lower megapixel count but better camera
https://www.gsmarena.com/xiaomi_redmi_note_5_ai_dual_camera-9120.php
if your specs match that you have the AI which supports quickcharge 3.0 speeds anything else is the pro version which that article suggests only supports 2.0 speeds both will work with quickchargers that are 3.0 fine just speeds will differ.

Quick Charge support ?

Does this phone support QC 3.0 or just QC 4.0 at India Only.
What Happens If I plug it into a QC 3 charger ?

I saw some news say that Xiaomi A2 lite is not sold in India? From what I heard then Xiaomi A2 support QC 4 in India and QC3 globally. Mi A2 lite only support QC 5V 2A. Not sure about these information.

What I've read the Redmi Note 6 Pro supports QC 3 in all markets, given its the same device on diff rom, it should support while it doesnt include QC 3 charger, Anyway I ordered mine along a QC 3 charger, at least it will not fry it.
And yest, it dont sell at India only the Mi A2 ("heavy")

Quickcharge 3.0 is supported by the SoC, so it should be supported unless Xiaomi disabled the functionality. I did see in one review that it does work.
Quickcharge 4.0 is only supported on the newer Qualcomm SoCs.
Quickcharge will not ruin your device, it acts like a 5V/2.1A charger unless the SoC tells it to charge at a higher voltage 9/12V.

I must test this..Official page says only 5V/2A charging..

qc 3.0 charger test with mi a2 lite
I bought qc 3.0 charger and made a test with my mi a2 lite. I did not see any difference with the 5v/2A charger.
Probably xiaomi disabled qc 3.0 support in mi a2 lite

I confirmed today with a QC 3.0 charger and a voltage/current meter. Device never went above 5V or 2A.
I wouldn't call it a deal breaker, this device will charge @ 10W(5V*2A) to a 14.4W(3.6V*4Ah) battery, so roughly a 2 hr charge time (1.25 hr to 80% and 0.75 to charge the last 20%).

Wireless charger
Does Mi A2 lite support wireless charging?

No It Does Not Support Wireless Charging.

When my Mi A2 Lite is charging it says 'Charging rapidly' and just almost exactly 2 hours from 0% to 100%. For a 4000mah battery that's not bad in my book.

So definitely there is only Fast Charging (5v2A) and no Qualcomm quick charge any version support. Hope it will be supported with new OTA bump to Pie

Mi A2 Lite will say 'Charging Rapidly' on the lock screen. I'm perfectly fine with the 2hr charge time, as 45-60 minutes of charging with this giant battery & 625 lasts longer than my Pixel XL ever had.

Can i charge my a2 lite with VOOC (4A) ?
Is it harmful for my device or is there any chance to blust the battery?

about the Quick Charge 4.0+

I want to optimize the charger's time speed by buying a new and trustful charger, but I don't have a clue about how many watts this Quick Charger 4.0+ on the redmi note 8 pro supports... someone may give me a little help? ?

Looks like even though the processor supports qc4.0, Xiaomi went with a qc3.0 Battery Charger chipset.
https://www.xda-developers.com/redmi-note-8-pro-teardown-confirms-quick-charge-3-0-support/

what!?! so it isn't QC 4+ ??
guess gotta see what's its maximum watts support for QC 3.0 then ;---;
