Do want to add that the S8 has wireless charging. I had a Nexus 6 and a Note 5, both with wireless charging - I can't go back. It is one those changes that impacts how I use the phone. I never need to plug into anything.
But you have to charge it in a special spot, while a regular phone can be plugged in anywhere to charge. I still don't get the wireless charging benefit, and I have an apple watch.
Wirelessly chargeable phones can typically be charged normally. What it buys you is convenience in that special place or two where you always charge your phone (bedside, work desk, etc.). I really liked it when I did have it and wish Apple offered it too.
