ON battery life, I would love some kind of dumb phone/ ultra low power mode that we can set when we just want watch mode at certain times and nothing else. I imagine that would give us a week of battery.
On the other hand, I just use my cheap Timex (with years of battery life) unless I need/want the more advanced features of the Apple Watch Ultra. I've been of two minds about the Ultra (and the Apple Watch generally). When I'm really using it like on a hike, I really like it. For more day to day stuff I mostly have notifications turned off and I rarely get legit phone calls when my phone isn't handy.
