Normally I keep a phone until severe hardware failure (spicy pillow, broken digitizer, not charging…)

The only thing that has gotten me to upgrade was the Boox Palma 2 Pro for it’s e-ink display specifically, due to eyestrain from reading on LCD, and my Galaxy A23 5G i received as a gift having its display start falling out (and fear of future storage/ram prices)

(technically almost a phone due SIMs only being supported for mobile data, but i use a flip phone for SIM-based calls/sms anyway)

with windows 11 it depends a bit, there’s cpus you were able to install win11 with some workarounds but that due to missing cpu instruction sets can’t run newer builds

so the latest win11 major update running on a machine below official system requirements is no guarantee of the next one doing so as well
