Now even at 80% original capacity, a Samsung can still last me throughout the day given that I am not watching videos constantly. The Iphone 6 back in the day would go to 40% in 3 hours, then suddenly to 5% in minutes.
Plus most people replace their laptop with a phone now. So the big screen size is a must.
I've gotten my EDC down to 1 leather ID sleeve with my credit card and drivers license in it, and my phone. This is probably still thicker then it should be, but it's soft so I don't feel the bulk or edges.
