It's all about the tail scenarios. Sure, my daily life is OK. But what about when traveling or spending a weekend day bopping around doing errands, getting a bite to eat, then going to a friend's house? I never want to think about charging my phone until I go to bed.

Yes that's it. I'm dumbfounded by the people arguing about the common life.

It's when you need the phone the most that battery life matters and it's usually when you are very far from your common routine/habits.

When you are in holydays in a foreign city, constantly taking pictures, looking up stuff, using GPS to find places, this is when battery life is the most needed and relevant. Inconveniently, it's exactly the times where it will be hard to find a convenient power sources, exactly when you don't have time to wait in a single spot to let your phone charge and precisely when it's a pain in the ass to have to deal with external batteries and other half-assed inconvenient "solutions".

It makes a huge difference.

But Apple doesn't sell useful technology anymore, they are in the business of selling high end luxury fashion, that sometimes cosplay as technology, so whatever I guess...

When you are doing all those things isn’t your phone in your pocket and therefore not draining battery?

When travelling how? By car you have a cable charger or wireless charger in 99% of cars I’ve been in

Planes have plugs Trains have plugs Ubers have plugs

It seems like that is a once in a while occurrence for you

In which case you’d be better off with a thin phone the vast majority of other days and pack a thin MagSafe charger for those once in a blue moon travel days and it would just be slightly thicker than a thick phone while the vast other days you’d have a thin phone
