Charging speed

[XDA_RealLifeReview]

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Redmi Note 8 Pro can charge. A higher rating indicates that it charges extremely fast.

Can anybody please confirm that the phone does support the QC 4+ and not only QC 3.0 by testing charge with different chargers ?

Xiaomi said RN8 Pro support QC 4+

Xiaomi said RN8 Pro support QC 4+

Yes they said that. But some articles said only QC 3.0 is supported

You prefer to trust Xiaomi itself who made this device or other articles who said Xiaomi lie about charging speed and some articles said it support QC 4+

it's too much time considering the fast charger

it's too much time considering the fast charger

it took less than an hour for me from something below 30% to 99%.
edit: i can provide a gsam battery image if you like to.

Note 8 pro does supports 18W fast charger. The charging speed is pretty good for me.

I did a test with my device. So at 4% battery, I put it in airplane mode. I used a 30W charger, with a USB Tip C - USB Tip C ports. It took 107 minutes to fully charge. Until 80%, the charging speed was about 13% per 10 minutes. After reaching 80%, the charging speed decreased. The phone reached 81% in 60 minutes. I logged the battery percentage and charging speed percentage every 10 minutes, and I included in a excel graphic. I attach this file. Maybe someone more tech savvy can understand more about the inner mechanism and if it is QC 3.0, 4.0 or whatever.

I have a QC4+ charger and a usb power monitor and it only shows QC3.0 on it`s display as the charging method on my 8pro.

I found it funny that using an old 10w charger takes about 15 minutes more to charge my device.
I keep using the old one as it produces less heat, and theoretically should prolong battery life.

Average charging speed with the fast charger provided with it, is 1 point rise per minute.

Which app is preferred to measure the current speed specially in Watts?
