Only alarms to wake up
I have stranger phone call anxiety and the other thing is spam/scam calls. Which thankfully my phone has been good at flagging/blocking.
Regarding notifications I used to have phones that either had LED blinking indicators or sound/beeping ahh, crazy used to just drop what I was doing to check it.
The kids that didn't survive were buried and no longer interact with us.
Neither of these calls often. Maybe once a year you get call like that. But when they call, you really want to pick up.
Can You guess why? Thats right - he also had a policy to not take phone calls from unknown numbers (especially foreign). They had to go to ours country ambassy in Spain (which took a while) and beg for help.
Since that day his father answers all calls :)
Only my close family are whitelisted.
Most time people call twice during an emergency. You could also say to call back again in case of emergency in your voicemail message.
I've added my family members to that exception list, and leave the phone on do-not-disturb mode 24/7.
I guess it basically comes down to: how likely is a call from an unknown number to be important for me? It turns out this is wildly different for different lives.
I know others probably can't do that, but it works great for me.
I deleted all apps that distracted me, Instagram, Facebook, Firefox, Email, Slack, Facebook Messenger, Telegram. I check the ones I care about on my laptop/desktop. I deactivated my Instagram/Facebook because I kept logging back into them and scrolling for a bit -- not for very long, but any free moment I'd look for entertainment there.
Any time I need some app, e.g. YouTube to show a video to a friend, or Uber to catch a ride, I'll download it and delete it once I'm done with my task.
I've found that my screen time has gone down drastically. I used to spend 3 hours a day on Instagram, Facebook, Hacker News. Now I spend closer to .75-1.5 hours, with about 50% of that being very difficult to trim down because it's mostly useful (1:1 texting, finding music on Spotify, using Maps). I still have HN, xkcd, and the NYT for reading, but that's not much more than 15-20 minutes of my day, which I think is acceptable.
I also put my phone in grayscale with reduced white point. This makes it much less enjoyable to read, and reduced white point makes it much more difficult to see/use, which reduces the time I spend.
It's a lot of effort, but it's so easy to get sucked into your phone. Every little moment when I'm bored I'd pull it out and look for something. It's so much more valuable to be doing nothing, and to not be controlled by little notifications on my phone when something happens.
I wish I could get an absolutely stripped down iPhone. I want Maps, Spotify, Messages, Phone, CarPlay, and that's about it. Maybe it would let me switch profiles for travel that has extra apps, or to some entertainment mode with a time-delay (e.g. if I wait 5 minutes I can open up Netflix). Something like the Light Phone [0] seems interesting, but not having CarPlay is a non-starter because I find it so useful. I suppose I could have two iPhones -- one for everyday carry that is barebones, and a second with the rest of my apps that I can keep in a drawer 95% of the day, but that sounds just so wasteful.
