>I doubt any phone battery is lasting 5+ years.
Just coming up to five years on mine and it is still at 87% capacity.

Edit: I just googled it. Apple claims that the iphone 17 should handle 1000 full charge cycles before reaching 80% capacity
I also believe apple’s claim is assuming optimal conditions. Real life is going to do a fair bit worse. So likely 700-1000 cycles for 80% if the pattern holds up.
If you are using “needs replacing” to mean “the device will be non-functional or risk permanent damage”, you can go significantly lower than 80%. In fact, I think most devices could go down to 0% battery health unless the battery swells.
I follow the estimate that lipos lose 2-4% capacity per year without any use beyond recharging for safety. If the battery sees daily use that number gets a lot worse.
My guess is everyone else is the perfect mix of hardly any use and winning the battery lottery.
Really it mostly depends on how heavily you use it, and maybe to a lesser extent charging habits (charging slowly, not charging to 100%, etc).
Big phones are overrated.
