Compared to my S8 it does not charge fast, is there a setting I need to enable for fast charge?
I thought this was a fast charge device

You have to turn off battery care or else the last 20% charges very slowly.
According to my research, with battery care it charges fast(8V 1,5A) until 50% of the battery, then it goes 5V 1A.
Are you using a Quick Charge enabled charger or the standard one delivered with the phone?
I did some tests today at work, charged from 0% to 90% with battery care ON, and bluetooth ON.
0:00 - 0% - 8,6V 1,3A
0:04 - 5% - 8V 1,3A
0:08 - 10% - 8V 1,3A
0:18 - 27% - 7,7V 1,3A
0:26 - 33% - 7,7V 1,3A
1:00 - 73% - 5,3V 1,3A
1:19 - 85% - 5,8V 0,6A
1:30 - 90% - 5,5V 0,6A
0:00 - 0% - 8,6V 1,3A
0:04 - 5% - 8V 1,3A
0:08 - 10% - 8V 1,3A
0:18 - 27% - 7,7V 1,3A
0:26 - 33% - 7,7V 1,3A
1:00 - 73% - 5,3V 1,3A

I don't have this phone but try installing Ampere from the Play Store. If you see it charging anywhere in the 2000+ mA range it's doing Quickcharge. Keep in mind it does so up until 80% I believe. At least that's what my Axon7 does but I believe that's how Qualcomm Quickcharge 3 is designed- to rapidly charge until the last bit to maintain battery health. Notice the numbers in the person's measurements above how it ramps down after 80%.
Also, if you purchase any 3rd party chargers make sure to only buy models Qualcomm says are certified for Quickcharge. There's a PDF on their site that lists all of the certified chargers.
My Axon7 will charge at around 2300-2400ish mA until 80% and then drop to around 500mA for the remainder. I also might have to reseat the cable if it's not kicking in.
But that last 20% is by no means quick. That's why these fast charging technologies advertise them with slogans like "15 minutes for 2 hours charge" or whatever. The slogan only applies to the quick charging timeframe - you will get a couple of hours if, say, you began charging at 25% . If you want to get a full 100% it'll still take an hour or more to trickle charge the last 20% or whatever.
Personally, I bought a certified Quickcharge 3 charger for my car and 1 for the house, the OEM charger I use at work, and at night I use an old charger that isn't Quickcharge. It's really mainly handy for the car when you need to get that oomph when you're out and about.
