Ideally, you’d only ever get a new phone case when you buy a new phone. However, wear and tear, accumulated gunk, and other factors might speed up your need for new phone accessories. You can try to stave off replacements by regularly cleaning the inside of your case to prevent crumbs and dead skin from accumulating and, you know, not driving over your phone, dropping it in a toilet, and letting your kid watch YouTube on it. But we’re all human, and those are some seriously unattainable goals.
