Phone broken

My smartphone (iPhone) has been broken since early May. Strictly speaking, it stopped powering on and stayed that way.
Connecting it to a PC doesn't recognize it, so I couldn't even back it up.

The process took time, and the replacement phone still hasn't arrived.
As of late May when I'm writing this, still no replacement.
(For the record, Apple and the carrier aren't at fault here.)

Meanwhile I can't see messages, and SNS and app data are completely gone from view.
I also listened to music on the iPhone, so music listening dropped sharply.

Things I always stay logged into on PC, like Gmail, I can still check — but trying to log into other services often hits phone-number auth (SMS text codes), so a lot of them are unusable.
I was shocked again at how many web services in the world are tied to one phone number.

(※ I do have an iPad, but it's almost the same as a PC — without a phone number you can't log into services, and (this may be my settings) I can't check mail to my carrier address.)

That said, I already lived with almost no SNS, so losing those services luckily didn't mess up my life.

There are inconveniences, but once you're actually in this environment, daily life didn't change much from usual.
If anything, less unnecessary information seems to reduce the load on my brain.
Opening apps out of habit stopped. (I canceled various services because of this.)

I want to keep cutting unnecessary information.
When the replacement arrives, I'm thinking about how to spend less time on the iPhone.
Somehow I need to reduce the triggers for picking it up.
At minimum, things like:
・Install only the apps I truly need
・Forward carrier-address mail to PC mail
・Build setups so I don't have to check mail and app notifications (delete apps, change settings, etc.)
・Power it off when I'm not using it
feel necessary.

Extreme take: if the main use of a smartphone is apps, leave that to a tablet and PC, and treat the phone like an emergency contact device.
In that case, a dumbphone-like phone for emergencies might be enough.

In the modern world you can't cut digital devices completely, but I always want to reduce them to the limit.

For gathering information and entertainment, some slack near that limit is fine — but as much constraint as possible is needed.

I'm not pushing conspiracy theories, but phones and web products are brilliantly designed to keep people's attention and interest on the platform.
They definitely affect intellectual work. You end up chronically scattered. Focus gets blocked, reading, study, and thinking drop — body and mind both take a hit.

I need to build systems that cut information that isn't important to me with high precision.
For now, my room tends to get messy — so before the digital side, I should start with physical decluttering around me.
