Iphone 13 is at 89% useful life now. Not bad after 2.5 years of fairly heavy use. My wife's iPhone 13 is more lightly used, she is also at 89%.
I suspect I am doing better then her because I slow charge with a 10 watt charger, battery never or barely gets warm. She uses a mag charger, it charges fast but wow, that phone gets warm.
I would love to get a new phone in the coming year and hope Apple comes up with something new. Im getting bored and wish for maybe a nice flip phone that someone else posted like a Samsung Galaxy Flip 6 OR a non flip phone but stellar camera like the Xiaomi 14 Ultra which I would LOVE in an iPhone format.
Except for those two I feel the "magic" is all gone in these phones of all makes. I guess we hit the limits of what can be.
