Confirm this has QC3.0? - Redmi Note 8 Pro Questions & Answers

I know that there is a teardown showing a QC 3.0 charge controller in the phone, but has anyone actually tried charging it with a QC 3.0 (and maybe 2.0) charger? Can you confirm that it does still charge fairly quickly? Don't really want to change all my QC chargers and powerbank. It will be a bonus if someone can test it with a Huawei FCP charger too as that charge my Mi8 Lite (QC 3.0) fast too.
Thanks.

will QC (2.0\3.0) will work with OP3?

hey there.. as the question goes.. if i have charger branded for QC 3.0/2.0 from qualcomm, will it charge fast the Oneplus 3?
cause SD820 should be embedded with that tech.
If someone can test it, and tell how long it charges.. would be great

You will not get fast charging with a QC charger, only up to ~2A.
OP3 does not support QC.
i currently own OPO, it doesnt have QC enabled, but i do charge at 5V/1A with QC charger.
OP3’s quick charge is VOOC, which belong to OPPO, not support QC
can anyone test to confirm, that at least we'll have 5V/2A?

Fast Charging Support

Hi all,
There's no mention of Fast/Quick charging anywhere about with this phone and every review I've seen specifically mention it's not supported.
I've just plugged my phone into a Qualcomm Quick Charge 3.0 power bank and the below icon has appeared. Is this a quick charge icon?
It definitely seems to be charging quicker than with other chargers I've used.
Yes, that is Qualcomm quick charge icon. It supports QC 3.0.
Mine says charging fast when plugged in so its supported.
And it goes really fast. I can watch youtube and the percentage will tick tock upwards every few seconds even when being used.
It comes with QC 3.0 charger... Hello...

The charger I received with my device definitely doesn't trigger the QC icon. I'm UK based and it's an EU charger through an adaptor so that might be screwing it up.

Yes, they give crap adapters from china always. Get this and a good cable. I have it. https://www.amazon.co.uk/dp/B075V42TN8/ref=cm_sw_r_other_apa_jpmQBbA9EPRB6

Portable fast chargers?

Any compatible yet? My old samsungportable fast charger bank from my s8 doesn't work with my pixel 3...
I use the Tronsmart Trim, it's PD 3.0 and seems to do the job pretty well.

Yes, I've no way of measuring exactly but the Pixel reports 'Charging rapidly' when plugged in to the portable charger.
Just got this yesterday from Amazon...was $25 bucks... Rapid charge works fine with the USB c to usb c PD charge.

Not Fast Charging in Car

So I have 2 Aukey QC 3.0 fast charging adapters for my car, however, neither work for the S10+. It either says slowly charging or charging. These adapters work fine with my S8+ so what gives? Did Samsung start blocking third party chargers or something, I've tried the factory USB C cable as well, so it's not that. Also, I use an Aukey QC 3.0 adapter at home which works perfectly fine, so I'm not sure if Samsung is only blocking 3rd party car adapters.
If anyone has a working fast charging adapter for their car, would you mind posting a link if its available on amazon? thanks
All of my current home and car chargers for the S9+ are working as fast chargers, might not be as fast as fast charge 2.0.

Has your car ever fast charged any phone?
Most cars simply fail at delivering that much power, fast charger or not

Yes, like I said, it works for my S8+. I have another adapter which is iRAG branded, that one works fine, so I guess I'll just re-order that one, if anyone is interested, it's this one:
https://www.amazon.com/gp/product/B073RQ915H/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
Surprising that the Aukey branded one doesn't work considering the S10+ still uses Qualcomm's Quick Charge 2.0, which is as old as the S6

Samsung S10 series doesn't use Qualcomm quick charge 2.0 rather its Samsung fast charge 2.0. There are a lot of confusion regarding QC 2.0, 3.0 to FC 2.0

Download Ampere from the play store, everything over 1600 mAh Is considered "fast charging".
You'll have more luck with generic fast chargers such as some made by Anker or your previous one instead of those marketed for QC 3.0.
My own wall QC 3.0 fails to charge over 1a, it doesn't even fall back to standard charge or QC 2, which would be around 1.5a+, meanwhile my Samsung charger and Anker Power core 2 do 2.2a+ just fine, there is clearly lack of compatibility with Qualcomm's protocol.

I use the Blackweb 5.4 amp car charger that I got at Wal-Mart. It has a 3 amp USB-C port that I use for my s10+ that I use and it provides fast charging. I also use the USB-C to USB-C cable that came with it.

LG makes decent products, even they can not compete with Samsung, but it helps to improve the diversity of the market!
did it work?

so did you get the Q.C 4.0 charger? did it charge faster? you might need a USB PD charger that can do at-least 21 watts.
LG is just imitating Samsung here, they did the exact same thing with my S8. I only ever fast charged that phone on my laptop.
I wonder if they're secretly trying to extend battery life, isn't fast charge rough on a battery?

I do have the fast charger in my car I cannot say it charges any faster but I don't know if it's certified by Qualcomm. I got it from Amazon
45W?
There seems to be disagreement between Qualcomm and LG. On LG's website it says G8 is QC3.0 in "Power & Performance" section of their Specs page, while QualComm lists G8 as capable of QC4.0 (but not 4.0+).

Which charger did you get and how well does it work?
Old post, worth insisting.
Bought G8, Korean, bit it's the same, only some different bands.
Like previously said I've read QC 3 on LG US website, but QC 4+ on Qualcomm.
I've bought two Hama wall chargers, 3 and 4+.
I also use the 65W PD charger of my laptop.
All three have same exact charging time.
So, how can this be?
Shouldn't 4+ be faster than 3?
If yes, than the G8 it's indeed only QC 3...
Has anyone tried a QC 4 charger yet? How does USB PD speeds compare to QC 3/4? I'm coming from OnePlus and debating about what charger(s) to buy. What's been the fastest chargers?
