Most iPhone reviews state that battery life is the platform's weakness, not its strength...

Here's an alternative way to look at it: I have a comparable sized phone and battery in the SE 2022, and I'm a light enough user that I only charge it 2-3x a week when it drops to 50-60%. I have a shortcut to notify me when it reaches 80% (for ideal battery health), so it's usually only on the charger for ~20 minutes at a time.

So, even though a Mini isn't great for battery life, it's also a small enough battery that quick charges throughout the day will top it off with minimal downtime.
