Charging speeds is really the only area Samsung really lags.
I also have the Oneplus 6T mclaren edition which has a 30w warp charge. Its really nice not to worry about battery being low because you can plug it in for a bit and get easily enough battery for the rest of the day.
EXACTLY... Like my M20P. I could just do a last minute charge in the morning before i take a shower. And leave with 90%...i know i know it isnt safe bla bla bla. Hahaha.
