does mi 8 support mi 9 27 watt wall adapter from mi wireless charging bundle ? Then I want to know charging speed difference in mi 8 original charger vs mi 9 original charger.i was planning to mi 9 original charger for mi 9 but I saw mi 9 shiped with 18 watt charger same watt as my mi 8 adapter.so I want to know will the charging speed be the same or faster in mi 9 adapter?
almost September 2020, and I have news for you ...
I'm using google translator because I speak Spanish, sorry.
August 30, 2020, I have stable miui 12 from xiaomi.eu.
I have the charger of the xiaomi mi 9 (the one that comes with the wireless charging base) and the charging result is as follows:
using the antutu app it says the estimated capacity is 96%. In 65 minutes it has charged from 3% to 87%, it is not as fast as the xiaomi mi 9 (change my mi 9 for a mi 8 and money) but I think it is charging at more than 18 watts.
According to Antutu, the temperature of the battery is 36 degrees and that of the CPU is 39, but before these temperatures were between 45 and 50 degrees.
I wait for your comments about it.
Thank you.
Yes it does, and it should be faster compared to 18w one that came with mi 8. (27w>>18w)
Currently doing a test to compare it with the Mi 9. Have both the Mi 9 and Mi 8 and I have the 27W charger. Currently testing the Mi 8 from 55% to 100%, doing the same with the Mi 9. Will update on this.
EDIT: 27W doesnt work on the Mi 8. It took 55 minutes to get from 55% to 97%.
I have tested my Mi 8 with USB-PD 2.0 and 3.0 Chargers.
QC3 18W - charges about 1,5% per minute at 2400mAh
USB-PD 27W - charges about 2% per minute at 3200mAh
QC4 is based on USB-PD with a few super awesome secret features, if you ask Qualcomm.
What's needed is a USB-PD (or QC4) Charger that delivers 3A at 9V.
The Charger needs a USB-C Port and you need to use a USB-C to USB-C Cable without any adapters.
But don't get too happy right now. I present you the problems:
1. 27W Charging only is faster up to 60%. With a charge rate of 3200mAh at 60% the battery voltage reaches max and the phone needs to cut the charge rate down. At 70% the charge rate is down to QC3 18W at about 2400mAh.
2. I tested this in a room at 22°C. Battery temp at 24°C.
After about 10 minutes (20% charged), the Mi 8 is getting too hot with more than 34°C. The charge rate immediatly cuts down to 2700mAh. After a few minutes it cuts down to 2400mAh and we are back to 18W QC3.
I have to admit, I already tried to charge my Mi 8 with a tiny USB Fan cooling the phone while charging at 3200mAh.
Yes, that works, but.... I mean.... Cmon, I am not gonna start building me an aircooled charging station.
Btw: I am on Xiaomi.eu weekly Rom. Not sure about the official Rom, but isn't Xiaomi advertising QC4 for the Mi 8?

With 27 watt adapter , charging speed still suck like 18 watt adapter:3 but device is cooler and it's like no heating at all. That's the only difference.
Well, QC3, QC4+ and USB-PD, they all charge at 9V.
QC4+ and USB-PD are just able to charge with about 30% more amps.
The high temperatures, when charging, results mostly of the transition of the 9V the charger has to send over the USB-Cable, in order to keep the amps low enough in the cable, to a max of 4.4V the battery needs.
This causes the battery to heat up, exactly like high CPU temperatures heat up the battery. Its a small device, thats all.
What I want to say is:
You are wrong. 27W chargers do charge faster, about 30% faster.
You charged from >55% to 100%, of course there is no advantage in comparison to a 18W charger.
You are right. Charging speed still sucks at 27W chargers.
I really appreciate the 27W charging. During the day, when my mi 8 is down to 30%, I can charge it for 10 minutes to get back to 50%. Thats a lot and most of the time it's enough for the rest of the day.
Every night, I charge my mi 8 with a 5V 1A charger. No need for fast charging there.

I came here to say pretty much the same thing, you will only see the benefit if your battery is low. So charging from 20% to 60% will show some increase in charge speed, from the there the heat protection mechanism via the kernel will slow down the charge rate. Its truly not a good idea to charge your phone too fast, as heat will decay the battery much faster.
Although it's nice to have the option if you are in a hurry. My charger is next to a large fan ( works fine, stays cool)
BTW, here is a great informational article concerning prolonging the battery and avoiding heat: https://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

The Mi 9 charges in around 55 minutes from 0% to 100%, the Mi 8 took 55 minutes to get from 55 to 97%.
Just wanting to say that it just isnt as fast as the Mi 9. The 27W charger does charge a bit faster, but only upto around 50%.

0% to 100% in 55 minutes is impressive. Although just from the numbers, with no personal experience, it's hard to believe. This would be a charge rate of at least 4000mA.
Can you do me a favour?
1. Can you try charging your Mi 9 with a QC3 18W charger and tell us how long it takes from 0% to 100%?
2. Can you try this app: https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en_US
and tell us the charge rate of the 27W charger and the 18W charger of your Mi 9?

Thank you, I was so close to believe charging next to a fan is the first sign of a serious smartphone addiction.
Can't wait to tell my psychiatrist about it

I don't know, flashing ROMs on multiple phones weekly can be quite addictive, and you knowv they are all getting charging next to the fan.
But hey, at least we aren't on drugs.

I hope you did not get the feeling that I was assuming that you were lying about the charge time.
Maybe you found out your charge times weren't what you first think there were and that's why you did not answer to this day.
Maybe I was wrong not believing you.
Everybody makes mistakes, it doesn't count who made them. What really counts is to make mistakes in the first place. I don't know any other way to improve.
Long story short: I want to apologize. Please come back and tell us about the charge time of the mi 9 with the mi 8 charger in comparison to the mi 9 charger. That would make this thread complete.
I am really interested if the mi 9 got any advantages in it's charging hardware. I can't find anything about it but it seems that the mi 9 really charges a bit faster than the mi 8. Looks like there are improvements made in the mi 9.

Hey, sorry I forgot to do it! Haha, my friend is currently using my Mi 8 because his phone's broken. I will ask him if he can bring it back to me when its nearly empty so I can compare.
I saw that the Huawei P20 Pro on Android 8.0 got support for Quick Charge 3.0. Does this still apply for Android 9.0? How can i check that Quick Charge 3.0 is working?
In my experience, installing AccuBattery seems to be a good way to test this. If AccuBattery shows a voltage much higher than 3.5v and a current higher than 1500mA then you're charging at 18W speeds or above. (on Mate 10 Pro, a QC1.0 10w charger charges at 3.7v and 900mA approx, while a QC 3.0 18W power bank (mi power bank 2 20k mah) charges at 1800mA approx and the bundled Huawei super charger charges at 4.3v and 4,000 mA approx.
Also make sure to use the Huawei 5A cable for best compatibility.

Does it take an hour to max out your phone? Then it's working dude..
Does anyone know of a good UK charger that would fast charge a Mi note 10. Its 30 Watts (10v 3a) I believe.
Thank you.

If you can buy Anker quick charge 3, USB c to USB c charger is very fast
I'm a bit puzzled myself regarding the suitable charger for the Mi Note 10.
Xiaomi specs say: "Supports 30 W charging. Packaging includes an 30 W charger"
Well, the phone runs Snapdragon 730G in which specs say: "Qualcomm® Quick Charge™ Technology Support: Qualcomm® Quick Charge™ 4+ technology"
So I'm not sure which charger should I buy.
QuickCharge 4 charger? 30W charger?
Helppppppppp
Help with the charger anyone?
Do I need to buy a QC4 charger?
Hello,
Did anyone try to charge the phone with more than 55Watt?
In the spec list it says that it supports quick charge 4.0+, but the snapdragon 888 supports QC 5.0+
What if I buy the mi 11 ultra charger? Do you think it will charge with 67 watts?
11 pro does, not sure about regular11
From my Research, it supports power delivery 3.0 and Quick Charge 4.0+ , So it should be able to handle up to 100watts, but I am not sure, I did not test
Quick Charge 5.0 requires a device to have two batteries and each battery consists out of two cells. (For us end-users this will of course look like one battery, we can't see how it is actually composed). Now, I now the Mi11 has two batteries but not sure about the cells.
I use my xiaomi 67 watt charger with qc 5.0
however it still charges only with 50 watt
Not work more than xxx way, doing support from mi ultra
