Short answer
Trade-in value depends on model, storage, battery health, screen condition and whether it is unlocked. Back up, erase, remove Activation Lock and use the estimator on Find Next Phone for a current figure.
Values change quickly after new iPhone launches, so check a live estimate instead of relying on old figures.
What affects value
- Model and storage.
- Battery health.
- Screen and body condition, including lines or cracks.
- Whether it is unlocked and not tied to an iCloud account.
- Original box and accessories (small effect).
Prepare your iPhone
- Back up your iPhone.
- Sign out of iCloud and turn off Find My.
- Erase all content and settings.
- Remove your SIM or eSIM.
- Clean the phone and take clear photos.
Faulty phone?
A phone with a green line or a cracked screen still has value, but less. Compare the repair cost with the trade-in difference.
Trade in or keep?
If your battery is worn, a battery replacement may be cheaper than upgrading. If you want newer features, trade-in credit can cover a large part of the next iPhone.
