    How much is my iPhone 15 Pro Max worth?

    Two generations on, the 15 Pro Max remains one of the strongest performers in the used market — it was the first titanium Pro Max and buyers still actively look for it. Battery health tends to be the deciding factor at this age, as many handsets have now passed a full charge-cycle life.

    • Storage tier (256GB, 512GB or 1TB)
    • Battery health after two years of use
    • Titanium frame and Action button condition
    • Genuine Apple parts vs third-party repairs

    Does iPhone 15 Pro Max storage affect its value?

    We buy the iPhone 15 Pro Max in 256GB, 512GB and 1TB. Higher-capacity examples remain scarce second-hand and consistently attract better offers.

    Can I sell a damaged iPhone 15 Pro Max?

    Yes. Cracked glass, degraded batteries and camera faults are all bought on this model, and it is old enough that repair parts are readily available — which usually means a better offer on a damaged handset than you would get on a brand-new model.

    Can I sell a network-locked iPhone 15 Pro Max?

    A network lock is not a problem — carrier-locked handsets are still bought, and UK networks unlock free of charge on request. An account lock is different: the device must be signed out of the previous owner's Apple Account, with Find My and Activation Lock removed through official methods. We never bypass security and we do not buy devices reported lost or stolen. Phone locks explained.

    Where can I sell my iPhone 15 Pro Max?

    Post it to us from anywhere in the UK, or sell it in person at 41 Church Street, St Helens, WA10 1AX or 48 Lowther Street, Carlisle, CA3 8DP. Both counters are open Mon–Sat 9:30am–5:30pm · Sun 10:00am–4:00pm. Bring valid photo ID — it is required for every second-hand purchase.

    Every valuation is confirmed after we have inspected and tested the handset. We never quote a final price sight unseen, and you are free to walk away at any point.
