My 12 mini had noticeably worse battery life than my 13 mini (current phone). So, the previous poster‘s experience sounds 12 Mini related specifically. Of course, battery life will be shorter with a smaller phone because of a smaller battery, but there was something about the 12 mini that really made it stink.
The previous poster here, typing this from 12 mini, which I like a lot, btw. 😉🖐️
I have no doubt that a new 13 mini will have a decent battery life for light-medium use for the first year or two, depending on one’s charging habits, etc. No question about it.
What I wonder, however, is a smart upgrade strategy for my 12 mini when it starts struggling with its usual tasks. Right now it still works fine, running the latest iOS 17 PB and I really have no reason to upgrade as yet. It’s original battery is still at around 87% (Apple-Coconut average) and I can get through the day with a few short top-ups.
So my upgrade options would be:
1) getting 13 mini while it is still being sold - ok, but very minor improvements over what I already have and two generations behind;
2) getting a regular 6.1” iPhone 15 - this will give me a much better battery, better camera, a Dynamic Island to play with, a USB-C to “rule them all” with my iPad and a more precise GPS. So pretty good, really;
3) not upgrading for as long my 12 mini is going, hoping Apple might give us a mini refresh at some point or bring back a 5.8” form factor, the later would be great.
So, basically, I will wait for the Apple event on 12 September and decide what to do then. I would not rush to buy 13 mini now, as Apple might still keep selling them and, even if not, there will be plenty of carrier and reseller deals to clear their shelves.
