Personally I've downgraded my phone intentionally, from an iPhone 14 Pro to an iPhone SE 2020 (the previous iPhone I had). It's slow, it overheats, the battery is short. But that's what I want -- the friction makes me really consider every use of the phone, and the occasional slowdowns frustrate me just enough to reconsider taking it out of my pocket for everything. It kind of "works" for me. Might get a battery pack though hahah
