What your phone is really worth: how the price is set and why it falls

What pushes the price up

· More internal storage — the gap between 128 and 256 GB holds even years later.

· The original box, cable and proof of purchase.

· Battery health above 90%.

· Remaining warranty — especially with a carrier.

· Sought-after colours and models with a physical SIM slot.

What pulls it down

· A screen or battery replaced with non-original parts.

· Signs of opening and misaligned panels.

· A carrier lock.

· A missing box and accessories.

· eSIM only, for buyers who want a physical card.

The depreciation curve

The biggest loss comes in the first year — often 30–40% of the launch price. After the second year the fall slows down. A new model release drops the previous one's price almost immediately, so timing matters.

A practical approach

Look at several current listings for the same model, same storage and similar condition. Your reference is the average of what actually sells, not the highest asking price.

If you would rather not deal with listings and meetings, we can buy the device outright or take it against the price of another one.
