“Absolutely amazing service! Prompt response to the submission of the request. One of the best parts is that where other companies you sell devices to try and barter down the price for cosmetic reasons on arrival, with Optimise Marketplace they ask for detailed photographs before agreeing a price so that - provided you know the functional aspects of the device are working - you know that the offer is ‘as seen.’ Received a pre-paid postage label within hours, paid by bank transfer the same day it arrived! Phenomenal service, highly recommended, will definitely use again!”

About the iPhone 16 Pro Max
The iPhone 16 Pro Max has a 6.9-inch display, the A18 Pro chip, a 5x telephoto camera and the longest battery life of the iPhone 16 range. Every unit is tested, graded and covered by our 12-month warranty with 30-day returns.
It has the same cameras and chip as the 16 Pro in a larger body with a bigger battery. Camera Control, the Action button and Apple Intelligence are all here.
- Who it suits
- Heavy users who care most about screen size and getting through a long day on one charge.
- Worth knowing
- It's a big, heavy phone. If you're coming from a standard-size iPhone, the 16 Pro is the easier switch.

Before you buy
- What battery health will I get?
- At least 85% on every pre-owned phone we sell — Like New and Good alike. If you'd like the exact figure, ask us on WhatsApp.
- When will it arrive, and what does delivery cost?
- Delivery is free. Every phone is sourced, inspected and checked before it ships, so it's dispatched within 1–3 working days. Within 8 miles of Dewsbury we hand-deliver it ourselves; everywhere else it goes fully insured and signed for. A paid next-day option is offered on orders before 1pm, Monday to Thursday.
- Can I return it if I change my mind?
- Yes. You have 30 days from delivery to change your mind on a phone or tablet — return postage is yours to pay. If it develops a fault within 30 days, you choose a refund, repair or replacement and we cover the postage both ways.
- Can I spread the cost?
- Yes. Choose Klarna at checkout to spread the cost, for example 3 interest-free instalments. 18+, UK residents only, subject to status; late fees may apply.
- How do I claim the warranty?
- Message us on WhatsApp (07990 134610) or email support@optimisemarketplace.com with your order number, the IMEI and a short video of the fault, before sending anything. We reply within one working day, and on covered claims we pay the postage both ways. The 12-month warranty covers hardware faults in normal use; physical and liquid damage, third-party repairs and battery health falling over time aren't covered. Full terms are in our Returns & Warranty policy.
