The 12 mini had really poor battery life. I have the normal 12 myself, and even that one has underwhelming battery life, but the mini was way worse. Don’t know about 13, but I would hope that recent advances in chip efficiency and battery technology would allow for making small phones with good battery life. Just please make it a little chonkier if you have to.

The Fairphone is interesting, but it is also enormous unfortunately

Well, I can’t speak for everyone else, but I can’t go back because they don’t sell any small phones.

I switched recently, and it is really good. It doesn’t have public transport yet (for the most part), and I rarely drive, but for walking, hiking and biking it is very nice. OpenStreetMap is shockingly well developed, I had no idea this existed. It has almost all the local businesses in my area, really did not expect that. It doesn’t have restaurant reviews and stuff though.
