Realistically you can buy something like a Fairphone that lets you replace most parts that wear out or get damaged, which definitely increases the overall longevity of your phone. Or that CAT phone that's supposed to be super durable if you're prone to breaking your phone. Or if smart phones aren't your deal you can maybe find the old reliable Nokia 3210, that phone does not break and the battery can be replaced.
If you have phone longevity issues then stop buying phones that are not designed to be used for a long time.
