I update my phone now when the battery requires two full charges to 100% to last throughout the day. But there's no feature I'm looking for. My current phone is a 13 -- so I guess it lasted five years, which seems crazy long for it to be perfectly fine from a functionality perspective.

I would probably still have my iPhone 12 mini if not for what happened to its battery. Loved that form factor, but the battery went from bad to worse in just a couple of years.

Hopefully these models have a longer lifespan before the battery life forces a replacement. If they truly offer 36 hours, there's more runway before they hit the < 18 hours point at which many people need a refresh

I went from a 13 Pro to 17 Pro and the battery life has been great.

Same, I went from a base model iPhone 11 to a base model iPhone 16. Assuming the trend line holds up, I'm in for an iPhone 21 next!

I'm on a 12. Paid really not very much to get the battery replaced recently, and I wished I'd done it sooner. There's at least another year left in this phone now if I want it.
