I'm plugging it in twice a day because its charge literally won't last longer than 3-4 hours use. And by 'use' it can be as little as just streaming music to my APP's, let alone using the screen.
Besides which it's 2022, iOS should (and probably does) already have battery management features that prevent the battery being degraded by being plugged in too often.
Have to admit i'm half tempted to migrate to an Android device, after being an iPhone guy for 10 years now. There are literally dozens available with this ballpark screen-size, rather than being limited to a choice of two (iPhone SE3 / Mini). I'm struggling to believe any of them have a worse battery.
EDIT: Probably not too difficult to find an Android phone with a USB-C port as well, instead of lightning, even though on the one hand Apple was pushing USB-C onto us before we were really ready for it with the 2015 Macbook, but on the other hand seven years later they still won't fit it to a bloody iPhone.
