Good, the biggest reason I have to buy a new phone is the battery effectively dying. I’ve already decided that when my current phone needs to be charged at least twice a day then I’m buying a phone with replaceable parts, something like Fairphone. From experience my phone has at least 2, maybe even 3, years left so maybe by that time I have a lot more options to choose from.
Batteries used to be considered to be a part that needs to be replaced as part of regular maintenance, because they deteriorate pretty fast compared to the other parts. The fact that anyone ever thought batteries should not be replaceable astonishes me.
The batteries last longer now than the phone is usable with newer versions of the OS.
