Yes I have a charger in the car, downstairs in my house upstairs in my house in the office and have a portable anker charger if I fly or go backcountry skiing for the entire day
A charger is like $50
Why would I carry around a brick in my pocket instead to save a few chargers
How does that make any sense
Also my iPhone 14 Pro lasts a full day 90% of my days on 1 charge
I use my iPad or MacBook most of the day for work or am driving
When you go travelling and do not want to carry around a backpack, and 1 day of heavy video recording, watching youtube on train plus 1 year of lithium battery degradation. That's when I want larger battery.
Most planes and trains in Asia don't have chargers. Maybe your country does. Your country is not the norm. Places that do have chargers are swarmed by people with tiny batteries desperately trying to charge up. And those charging spots charge about 1% every 15 minutes.
As someone who's been all around the world and goes places every week, I'd take a battery that lasts all day and charges when I sleep over needing to stop and try to get another 5% of charge wherever I can and constantly being on the lookout for chargers.
Also, people go into nature. We take hikes and walks in the park. It's nice to have a map there. It's also not easy to charge in the middle of the forest. And there are lots of people outside and needing good batteries. Nobody is staying home 90% of the time.
Aside from desiring a longer battery life, you'll likely be shocked to hear that some of us (non-iphone users) still use the Aux jack and the SD card slot too!
Those who commute to and from work by car can charge in the car
Those who work in an office can charge at the office
Those who are at school can charge at school
