It's my (incorrect?) assumption that going from a 6 to a 6s would buy me another year worth of acceptable iOS speed. My best option may be to deal with the performance and get my 6+ refreshed by Apple. Thinking about it, I haven't added a new "must use" app in some time. Maybe refreshing my 6+ is the way to go.
