For a phone reviewer probably this means something (not sure if it’s article worthy, but there, we have an article) , for a regular user 18 months should be the bare minimum to use a phone, I am aiming for 3-4 years if the hardware doesn’t fail and Its still getting OS updates.
For my next phone I will try to buy something which can last for 5 years if possible. I hope we will have more great sustainable options in the coming years.
