Actually, I think the camera & battery life are currently the most important features on a smartphone. I take all my pictures with my S8, casual or vacation and I'm thrilled if the next models are coming with a even better camera. Battery wise, I think that by now the minimal accepted performance is a full day on a single charge, with normal use, 4G and Wifi. Upgraded to the Samsung flagship every 2 years in the past 8 years and battery life was always within this acceptable limits.
