I have the exynos variant of the s9 (if that is at all relevant). I've been really disappointed eith the charge times ive been getting. it takes about 2 and a half hours to charge the phone with the fast charger that comes out of the box (and yes, fast charging is on.).
How long is the s9 SUPPOSED to take to fast charge?
