Smartphones are inconvenient in size and don't fit in pockets. There's no great solution for running with a phone. They're fragile and heavy making them easy to break when dropped. They act as a constant attention drain alerting you to every tiny thing that happens. They have terrible battery life.
You could go back to having a flip/candybar/slider phone with multiple days of battery life on a single charge that can use all of your messaging services and make calls. Add a few Uber shortcuts, a media controller, and a nice camera and you have the perfect pocket companion.
You could have a nice tablet for everything else like social media, multimedia, games, and streaming, - even one that is functionally a laptop if you're going to need a bag for it. Let it run in a low power mode so that it can drive streaming music to your bluetooth headset and you can use your cell phone as a basic media remote.
Basically run the iPhone/Apple Watch model, but with more devices with strict (but customizable) limitations.
If you go jogging, let the cell phone consume more power to stream music so you don't have to carry any other heavy gadgets to stream to your headphones. If you have a smart watch, let it stream cached songs and make calls in case of an emergency and ditch the phone altogether.
And you could even have a regular smart phone in the mix if that format is the best for the situation, but I really hate constantly needing my giant phone when I go anywhere.
