Aren't all the major manufacturers clustered around roughly the same battery life?

Sure, there may be an hour or two's difference between equivalent models from different vendors, but it's nothing like the Garmin vs Apple watch situation - they're all in the same "it'll probably last a weekend, but definitely not a week" ballpark.

If you don't have concerns over security, don't care about AI, don't need niche apps, don't need tech/nerd apps, don't worry about vendor lock-in, I can totally see caring about battery life.

So how many days does your battery last? No that isnt a good question, How often do you run out of battery? No that isnt a good question, android users aren't running out of battery.

How did Apple convince you this mattered?

> Additionally, Apple isn’t an advertising company like Google.

What does "advertising company" mean? Apple does in-fact sell advertisements[0], and relies very heavily on marketing to convey their value proposition.
