Five changes that matter more than the watch itself
The most common question after the last post wasn't about the Garmin or the Apple Watch. It was some version of: do I need to buy the expensive one, or was it the setup? It was the setup. Every change below works whether you're trying to go watch-only or just want your phone to leave you alone more. None of them cost anything.
Cut your notifications down to a named list, not a category
Most phones let you mute by app. That is the wrong unit. The right unit is people. Pick the five to ten humans who get through regardless of focus mode, by name, and silence everyone else by default. Group chats, work Slack, promotional anything: off unless you go looking. The list is short enough that muting it feels like a real decision, not a setting you forgot about.
Delete complications before you add them
A watch face with twelve complications is a phone home screen with worse typography. Every glanceable widget is a tiny invitation to check something. Keep the ones tied to a decision you actually make in the next five minutes: time, next calendar event, current heart rate if you are mid-workout. Weather, stocks, and step count as a permanent fixture are things you can check on purpose instead of being shown constantly.
Solve 2FA before you need it, not during an outage
This was the single biggest source of friction, and it is the one thing worth fixing before you change anything else about your phone habits. Print your backup codes for anything that offers them and put the paper somewhere you would actually find it at 11pm. Move what you can to a hardware key or a watch-compatible authenticator. Do this now, while you are calm and have your phone, not later while locked out of your bank.
Decide about the camera on purpose, don't just lose it
Photos are the real cost of leaving a phone behind, not messages or maps. Decide in advance rather than discovering it mid-week: carry a small dedicated camera, accept you will take fewer photos and be fine with that, or keep the phone for this one function and turn everything else off. Any of the three works. Drifting into "I guess I have no camera now" is the version that actually annoys you.
Make the health data answer a question, or stop collecting it
Sleep, HRV, and training load are only useful if something happens because you looked at them. A number that sits in an app you never open is not tracking anything, it is just background battery drain. Pick one weekly moment to actually look, and pick one thing you will change based on what you see, before you decide the metric is worth tracking at all. If nothing would change, turn it off and get the battery back.
None of this requires the watch that started the last post. It requires deciding, once, what gets through and what does not, and then leaving that decision alone instead of relitigating it every time something buzzes.
