So when I'm at home it can easily last a couple days. If I'm traveling by air, or other rare occasions where my phone gets heavy use, I have a slap-pack battery to stretch it out. I'm more likely to resort to that if I'm traveling and I forget to charge it: it's obviously not as much battery as a bigger phone, but for 99% of days, it's more than fine.
It serves my purposes, and fits in more pockets than the big bricks do. I wish Apple would learn to count as low as several million, and go back to accommodating the smolphone niche, but their current policy seems to be that if a product doesn't sell enough units to supply one to every resident of a mid-sized European country, it isn't worth manufacturing. Pity.
Right now for example, it’s at 44% after 24hrs from 100%. This is pretty sufficient for me
