the mi max 3 supports QC3.0 charging, but does it support the PD charging standard that google have been pushing for as the open standard? would be interested to know if there was any benefit in faster charge times.

I just purchased an LG G7 ThinQ on Verizon in the US, coming from an LG Optimus G Pro, purchased in 2013. It's being shipped right now, so I don't have it to play with.
With that said, I'm a newbie to quick charging. I see that the phone comes with a QC 3.0 block, and that the phone is listed as being QC 4.0 compatible, as per Qualcomm's website.
I'm looking to order all new cables and chargers to take advantage of the higher charging speeds that this phone can allow. I'm not understanding though whether I'd be better off buying a car charger that is QC 3.0 or has USB PD. I realize that the USB PD would be the way to go for laptops and larger items, but for our phone, is there any difference? I do realize that I'd need a dual-ended USB C cable for the PD charger.
Also, has anyone tried using a QC 4.0 charger on the phone, and although Qualcomm says the phone has the 4.0 hardware, has LG enabled us to use it?
So the LG chargers can deliver 9v 1.8A.
The phone will recognize my 18w and other 45w PD charger, but I haven't managed to see any difference in the charging speeds, and more annoying, charging is pretty slow when screen is on.
I wanna buy a USB meter (PD compatible) to see what's the phone actually asking for, but I assume that it just sits at 15w max.
The reason I have a PD charger is because it allows you to have longer USB-C cables and it's compatible across more devices, like I can fast charger my Huawei Mate 10 pro with it, you can also charge iPhones with it.

This thread could be useful for you too: https://r.tapatalk.com/shareLink?ur...share_tid=3787343&share_fid=3793&share_type=t
USB PD is an entirely different language than QC 2-4. They negotiate and handle power different from each other. If you plug USB PD into a QC device it should default to 5v, 1 or 2 amp standard charging.
Use only QC 3.0+ equipment. That will get you the rapid charge you're looking for as it speaks the right language for the phone. I dont believe LG has enabled QC4 standards in the firmware although the chip supports it.
LG G7 is also wireless rapid charge, i get an almost QC speed on a 15w ravpower and umdigi wireless pads. Took me a few to find ones that were quality and charged fast. Most of the "10w" chargers dont actually put out 10w so they dont charge fast.

QC 4.0 is actually compatible with Power Delivery, Qualcomm did that in fear that Google would make PD mandatory.
And there can be handshaking between previous QC devices and PD chargers, since the most basic profiles are kind of standard (max 9v 2A).
So in this way I can fast charge a S8, the LG G7 and any other QC device with the PD charger and I can charge other PD and QC devices with my Huawei fast charger power bank (it's based on QC 3 delivering max 9V 2A).

Funny i was just reading an article about that. I suspect that would be a firmware compatibility issue again, as in: did LG enable it.
Great feedback and perfect timing

I just wished that phones would support higher charging rates via the PD standard.
I'm mostly sure that neither the S8 nor the G7 are taking full advantage of the max power output of their charger for long.
I thought that the charger might be under delivering, but connecting my PD 18w charger results in the same situation, I still need to measure it (need to buy a USB meter to have more details).
But using the same 18w PD charger I can charge the Mate from 20 to 50% much faster than I can charge the G7.

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%).

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?
While the Redmi Note 8 supports 18W fast charging and Qualcomm QC 3.0 can it support the Mi 27W Charging ?
i think it don't support 27w ,but even it does you don't wanna lose your battery
If you want to get rid of it just send it to me ^............^

Only support until 18W
Hello, can Mi 10T support charging speed higher than 33W? Does anyone know the cap on fast charger and can we use the 65W gan chargers to charge it upto 65W?
I've read somewhere that it can work with 65w chargers but I can't find that link, so take it with a grain of salt...
33W max, 65W charger won't make a difference.
My question is about fast charging. What it's the maximum accepted by the device? XIaomi charger is 33W on it's quickest mode. According to the device chipset (Snapdragon 778G 5G) it supports QC 4.0+.
It supports more wattage than 33W? And QC 4.0+ chargers with USB type C cable on both sides?
Nobody?
Since the advertised charging rate is 33W there is no reason to believe that a higher speed is possible.
