I own a Nokia 8 for 4 days now, really like the nice clean look and specs of the phone!
One thing though, fast charge doesn't seem to work!
When I plug in with the supplied adapter I see fast charge appear on the lock screen, followed by Slow charge->fast charge->slow charge->charge.
Takes over 2 hours to charge the phone from +/- 20%
This doesn't seem right...tried it with several USB C cables and with another 3.0 adapter, same results every time.
I've been on Oreo since first boot, so I don't know if this is an oreo specific issue.
Fast charging never seams to work for me. Never see Fast or slow charging. Just Charging from 24% 3 hours to full.
Using standard charger.
You have to realize that fast charge doesnt mean you will get full 100% in 30 minutes.
You will get 50-60% in 30 minutes because thats the point of it, you get up in the morning and go to work and you realize holy sh*t my battery is dead, so you plug it in and you can get more than 50% in 30 minutes, like thats the whole point.
If you want full 100% you need like 1 hour and half, I think its normal (if not someone correct me) they need to prevent battery damage and also you can notice if you go full 100% the battery drain is much slower than if you just charge it for 30 minutes. So all in all, the fast battery charge is only good if you are in hurry and you dont have time to fully charge your phone.
I am using Anker PD charger on my N8 and charging speeds are pretty good. I have never seen rapid charging on my phone. Not even with official charger. I am not using the official charger because of lack of power slots on my desk and the Anker PD charger is all set up from 6P days. This thread is the first place I even realized that the phone is supposed to show rapid charging on QC3 charger! My power bank is QC3 capable and even that shows the regular charging message on the phone. Would keep an eye out in future to see if that changes.
