Samsung S21, at 3 years old now. Surprised it was that old to be honest. Got into the habit of buying the handset outright and trying to ride it into the sunset for as long as possible. Usually until the battery starts to give in or performance becomes an issue but currently no plans to upgrade or change. I would say the temptation to upgrade year on year isn't really there in terms of offerings or performances, which saves a good bit of money.
