Does mi a2 really support QC3/4 - Xiaomi Mi A2 / 6X Questions & Answers

I have read several topics about this and still doesn't understand. I was one step from buying QC3.0 from KUULAA before had a bit of test.
Im running pixel extended rom, that can show on screen charge info. The stock charger is out of question. I also have chargers from mi 4 and samsung s5e. And both of them showing 10W charging - 2.4A and ~4.5V. Then i got for test 2 more adapters - one from Pixel 4 and Redmi note 9 pro. They suppose to be QC3+, allowing 18+W charge. Yet - both of them showed exactly the same numbers ( tested with 10% battery).
So the main my concern - im not even talking about qc4, i didn't even saw that qc3 charge that suppose to be 18W, not 10W.
Maybe there is not support from rom? or is this support should come from kernel? Since sd660 allowing QC3/4 but it's own specs

Will a Lenovo P2 12V fast charger work for Note 4

Hey there guys
I am a audiophile who wanted to go for Lenovo P2 just for the sound quality it delivers through headphones. But due to my recent expenditure my budget has taken a hit and I don't think I will be able to afford it any more.
The other reason I wanted to go for it was because of it's fast charging capabilities. Redmi Note 4 runs the same Snapdragon 625, so I was wondering if I can use the Lenovo P2's original 12V charger to fast charge it. is it doable or will I be ruining the phone ?
Sometimes I still think I should still wait and just go for P2 its just that I just love my music ... But I love Xiaomi too, I have bought xiaomi phones for all my family members. I don't care about amoled display and stuff ... I just love quality music and good battery life and terrified of overcharging my phone through conventional slow chargers. (I never sleep with my phone on charge)
Sorry bro it won't work.....
The kernel of RN4 doesn't support fast charging(although the processor does)....
You will need to flash a custom kernel to enable fast charging just like radon kernel in case of RN3....

Did u buy lenovo p2 and does it have audio issues with headphones...
I am having sennheiser urbanite on ear with 18 ohm impedance.
it will not work and even if it is enabled it could damage the phone because the components of the phone were never specced/made to support quick charging.
This is the first time that I'm reading about "overcharging" your phone over night. I've been using smartphones for 7 years now and have charged them overnight about 90% of the time, save for those days with heavy usage when I ran out of juice in less than 12 hours. Care to explain what you're talking about?
OP, wait for 8.5 MIUI update. it is going to enable QC/fast charging mode.
625 supports fast charging but it was not enabled by MIUI. In latest update 8.5 it's going to work as per features mentioned. Check Mi 5 device. for reference.
But "Mi 5" is already quick charge 3.0 enabled at the beginning, comes with a fast charger plug out of the box.. Just look for the specs everywhere

But OP using Redmi Note 4 Snapdragon Mido version.
Also SD 625 supports quick charge but it's not enabled by Xiaomi in MIUI.

There was news earlier about MIUI 8.5 with fast charging support in MI forums. Also MIUI 9 coming in few weeks I don't know MIUI 9 will support fast charging or not.

You need to do some research regarding overcharging. Hopefully this article below will enlighten you.
https://www.google.com/amp/www.androidauthority.com/battery-myths-688089/amp/
Quickcharging isn't that good long term for your battery. While it's safe if it's supported officially for your phone, it really shortens the lifespan of your battery. The amount of cycles basically. It'll start to last less and less much faster than just charging it normally.
I know it's bad for Li-ion batteries, and I think it's even worse for li-polymers because they last even less cycles in the first place.

Mi Mix Factory Charger/Type C USB Question/Issue

Hey guys,
A few weeks ago I made a thread about my Mi Mix NOT detecting on any PC despite trying different Type C usb cords and the factory one.
I've never really timed how long it takes to charge my phone and recently I downloaded this Ampere app that measures the voltage and mah.
My Mix was at 40% and I plugged it in and left it in for 20 min and checked the app. It said something like 3.7 voltage and charging at 120mah minimum and 190mah maximum.
From what I'm reading, thats really bad.
So I plugged my phone in with an Anker Type C usb and a charging block from an LG 5.
Phone was now charging at 1600mah ish.
I'm assuming there is an issue with either my charging equipment AND / OR the charging port of my Mix. I've already ordered a new charging port from aliexpress 3+ weeks ago because of my PC unrecognized issue.
Anyway I just want to confirm that getting 120mah- 190mah on the stock charger is NOT normal?
I've ordered this https://www.amazon.ca/AUKEY-Charger-Samsung-Qualcomm-Certified/dp/B00RJO6AHM
and another Anker Type C cord to replace.

I don't have it with me, but I think the original Chinese charger that comes with the Mix is a 2.5A/5V one.
I've never used it, don't trust the Chinese chargers, rather have used an original Xiaomi EU approved (CE marked) charger that came with a Redmi Note 4.
That charger is "only" 2.0A/5V, so you don't get any "fast charging". But the Mix will still get fully charged in max 3 hours, which is fine for me.
And I figure the battery will last longer, it gets quite hot when charging at higher rates.
I know because I tested on a Mi Note 2 which came with a 3.0A EU approved charger. That charger works fine, really fast, and I trust it from a safety point of view - much heavier and thicker than the Chinese one.
But I charge the Note 2 with the 2.0A charger also, to spare the battery.
Normal charging current is 1500mA and up, depending on the chargers capacity. It will be less towards the end of the charging cycle, when the battery is nearly full, and sometimes also in the beginning, for some reason.
Don't understand why, never figured that out.

well it sounds like my factory charger is messed. 190ma when it should be getting at least 1000ma. I hope that the Aukey charger I ordered is safe for it, I've done some reading with other xiaomi phone owners and they've purchased it but I haven't seen a Mi mix owner review it. It says its CE approved.

Aukey has a good reputation, but I prefer the Xiaomi original EU approved chargers, just because they are "Xiaomi". (and I am located in the EU, of course.)
There "might" be some sort of intelligent interface built in that especially suits the Xiaomi phones.
No particular reason to believe so, just color me superstitious.

i understand you. It is typically safer to always go with factory rather than aftermarket. But in my case, my phone is not charging correctly as I'm only seeing 190ma on the amp meter.:crying:

That can and does happen on certain custom ROMs and rapid charge doesn't kick in all the time. I can also say I had this issue on lg g5 and the charger proved to faulty on this occasion. So try the new port with old charger see how it goes. If no improvement try a different charger, the ones that come with the phone are very good. IMO

the new charger and cord are getting me fast charge now!
Bought a CHOETECH 50W 6-Port Desktop Charger last year and attached it to my bedside table; one of the best purchases I've ever made; quickcharge 3 on two ports and one power adapter in place of the 3 or 4 individual chargers I used to have. Bargain.

OnePlus warp charge comparability ?

Does anyone know/Think that the OnePlus warp or warp charge 30 power adapter would work with the Realme X2 pro ?
I know it will not be as fast but I can get one for free from oneplus referral points and it would be UK 3 pin.
Realme says the phone is compatible with other charging technologies like quick charge.
I will test it with my Oneplus 6T charger once I receive the phone and of it works I will get another one from Oneplus

I need a UK adapter but have purchased one so will be using the vooc charge occasionally when needed,
As these batteries only have certain number of cycles I would prefer to charge the phone with something else on a daily basis.
I'm interested in maintaining the battery for a few years so would like to keep it somewhere in the 45 to 85 range which has worked well for me with all recent phones I've owned

I hope you're right, because i haven't understand if supervooc is good or bad for this phone.
So, you can buy any qc 3.0, i like Aukey

I don't think it's necessarly bad for the phone but I don't trust it either. I have read in many reports it is quick charge compatable and I've heard that the OnePlus dash charge has worked also. I personally have no issue with these slower charge speeds and actually prefer them.
I will use the 50 watt in times I need it otherwise I will use the other ones
There is 2 batteries in the X2 pro and from what I understand the 50w is split between them both.... So it's more like 25w per battery as apposed to a single battery taking a full 50w. I personally wouldn't worry about it and enjoy the rapid charging.

The phone has 2 batteries... Each charging at 25w so it is ok

Not necessarily, whether there's two or one battery,each will need to be maintained to some degree or they will degrade
I always charge it over the night with an old and slow adapter from my LG g4, if I need a boost, I use the vooc One, did the same with the previous huawei mate 10 pro for 2 years and battery is still as good as the first day [emoji6]

I got a warp charge 30T charger from OnePlus but am yet to try it. Ive decided to just stick with the 50 watt for now,I can tell you that my OnePlus 6T charger worked fine,charging at full speed around 27 watt(or whatever it is)

Question Has Redmi crippled this phone's charging capabilities?? - Redmi Note 10 Pro Slow Charging

I'm planning to buy the Redmi Note 10 Pro considering how feature packed it is for the price . But a bothersome fact I've noticed in multiple youtube reviews, especially the Indian variant is that the phone is charging only at a power close to 25W when the charger is 33W and the hardware present inside is more than capable of doing that
Is it hardwares or software issue? Or is Redmi purposefully limiting the charging speed?
In my European variant, The in-box adapter says "27.0 Watts"
so in some variants came as 33 watts and other with 27
No problem here with the UK variant using the supplied 33w charging brick and cable.
Poland (So EU version?) here, 33w charger in the box. Charges 33w without problems. Official dist.
Edit: Got SS for You

Accessories Huawei 65W charger.

Hi guys ! I have Huawei 65W charger. Can i use that with my Mi 11 Ultra ? I was thinking is here why not to use it but I don’t want to fry something inside with long term usage.
This is a picture with the official xiaomi eu 65w charger. You can compare it as well to see the differences
It probably won't charge at 65w
I have a huawei super charger from my mate 20 pro (40w) and if I plug it into a Samsung or a realme or xiaomi etc it charges at about 10w
Huawei phones can detect the correct super charge brick and even using a non huawei cable will probably cripple your charge time
Thank you guys !
As far as I know (I have yet to recieve my device, but I do have a compatible 65W charger) it should be able to charge at 20V 3.25A (65W)
Worst case scenario it will just charge at the minimum speed available. There are all kind of handshakes and confirmations that happen before power is delivered from the charger to the phone.
Keep an eye on the battery temp... avoid draining battery below 20-30%
I have for example a type c charger brick from my hp elitebook laptop.
It has the same V/A ratio to do the 65w charging as the original xiaomi charger i posted above.
It does not work charging at 65w with the mi 11 ultra.
Be careful what charger you use and also the cable is very important !
I also use this type c adaptor to 3.5 and type c adapter ( to charge the phone and listen at the same time ) also this is the cable i use with my charger.
Hello,
I believe the CN version comes without a charger, does that apply to international version as well? In all unboxing I've seen of international version they came with a charger, want to confirm by anyone who got his international version since mine still needs 2 weeks to be here. Anyone can confirm please?
