After 2 years of regular usage for my 12 mini I can confirm battery life was a problem. In fact it was the main reason I got a new phone.

Realistically I would have been fine with a non pro model but I ended up getting a 14 Pro for the high refresh rate.

I've used it on a couple of headless machines over the years primarily as a host for docker containers. It's been mostly great but those few times it has broken was really annoying. Nothing I couldn't fix and never needed to reinstall though.

That being said I'll be reconfiguring soon and I thinking about switching away and using Debian.
