## The question

With newer iPhones out, older Pro models get cheaper on the used market. How much do you save by going back a generation or two?

## What to weigh

Compare the same storage size: a 128GB phone and a 256GB phone of the same model are priced differently, and the table lists them separately.

Check the battery health figure in the listing. A lower-priced phone with a worn battery can cost more once you add a battery replacement.

Make sure the listing says unlocked (or your carrier) and that the phone is not iCloud-locked; an activation-locked phone can't be set up.

Newer models get software updates for longer, which is part of what you pay for in the price gap.
