No need to be sedentary as there are fast charge mobile charging pacs, battery containing phone cases, fast charge vehicle chargers, and wireless chargers in more and more retail businesses. Before wireless charging was available for Samsung phones I carried spare batteries, a real nuisance as far as I was concerned. A pocket full of spare parts. And after wireless charging backs were available for Samsung phones I purchased the the backs and spare batteries. But wireless charging and vehicle chargers removed the need to ever use the pocket full of spare batteries. Batteries sealed in the phone allowed for metal and glass phone construction most folks were asking for, no need to have a spare battery or two for each model phone a person uses as well as separate battery chargers for each battery size. From the fact that the Note 5 is the most popular phone in the US beating out all others including iPhones I would suggest that either most of us are "sedentary" or most of us prefer the advantages of a phone with a sealed battery over a phone with a removable back cover to allow batteries to be swapped out.
