Phones
You don’t really need an 8-core CPU and 12 gigs of RAM for making calls and browsing the web, which is what 95% of people use their phones for. Not even buying such phone for the sake of longevity is worth it since most manufacturers drop support for their phones after 5 years at most.
A Xiaomi smartwatch. I never found any good use for its “smart” features and I had to charge the fucking thing all the time. So I ended up dropping it after a year in favor of a regular digital watch.
