I’ve had an iPhone 12 mini since launch and the battery life has become pretty abysmal. However, I’m reluctant to replace it with a newer, bigger model. My battery health is sitting at 86%, which really doesn’t sound that bad, but I feel like the actual battery life is way worse than when I bought it. Has anyone replaced their battery around this percentage, and did it give a noticeable boost?

Yes, and yes. I did this with an iphone 8, I think, which basically gave it a few more years of functionality before the advances to cameras and processors became too great to ignore. I used a kit from iFixit which was pretty easy to use.

FYI: I think the way to gauge your battery is to look up the number of charging cycles it has had. If it's over 1,000, that battery is past its operational lifetime.
