Battery anxiety is just too real.
I don’t think I mentioned it but my sister uses a 12 mini that she’s had since launch, but the way she makes it work is that she’s one of those people that uses a non-smart flip phone and just uses her iPhone in those situations where apps are required (e.g., Ticketmaster app to show tickets at the gate), using her flip-phone’s hotspot to connect her iPhone to the internet. Unless you have a similar use case or are close to chargers and external battery packs all day, I don’t see how you could make it work.
I remember battery life being “not good” back when I had my first 13 mini on iOS 15 but I don’t remember it being this bad, so I’m hoping the new OEM battery at least helps. I’d still love to use the mini, maybe on weekdays where I’m more likely to be at work during the day and home at night, and switching to the 16e for weekends and trips.
At least now I know I wouldn’t be happy with a 17 Air, if the rumored battery life compromises are true. My bank account thanks me
