Not very fast, there's some convenience in wireless charging, but I'm not a fan of it.

Thermal battery throttling as of 38°C?
My Galaxy S10 (EU/Exynos, stock) starts to reduce charging power from 11W to 6W above 38°C battery temperature. Test have been made with different original fast charging power supplys and wireless chargers. When i use a fan to cool no power throttling at all. It's summer now in Switzerland and i stated much higher charging time. Normal?

Strange. My s10 is exynos as well and the option is there. I use wireless charging occasionally for convenience but prefer cable charging (set to standard mode). If plug in Samsung charger it says Fully charged in 1hour 20 minutes. With other charger (Huawei) it says 2 hours 30 minute. So I think it depends on the plug and its output power. Also I charging my phone when it is around 10%.
Oh and one more thing: if using wireless charging phone gets hot.

Means that Samsung reduces charging power as of 38°C to prevent more heat and therefore reduced battery life... makes sense.
