After iPhone 18: compare used 15, 16 and 17 quotes
Updated 2026-09-14
Apple announced iPhone 18 Pro and Pro Max on 9 September 2026, with initial availability from 18 September. For a reseller comparing older models, the useful next step is to request fresh, comparable quotes. The announcement alone does not prove a price drop, a new supply of used phones or a best buying date.
Start with the order your shop needs
Choose the exact iPhone 15, iPhone 16 or iPhone 17 variant, capacity, quantity and destination. State whether you can accept mixed colors or grades. Keep alternatives on separate quote lines so a cheaper configuration does not obscure the comparison.
If your request is for the new models instead, use the iPhone 18 Pro / Pro Max guide and ask about availability. It is not a confirmed stock listing.
Compare the same fields on every quote
| Field | What to align |
|---|---|
| Date and validity | Issue date, expiry and whether the units are still available when you approve |
| Exact device | Model and variant, capacity, color mix and quantity per line |
| Version and SIM | Purchase market, A-number, physical-SIM or eSIM requirement and destination-carrier compatibility |
| Condition and battery | Written cosmetic standard, minimum Battery Health, parts history and replacement-parts rules |
| Unit status | Network lock, IMEI status and Activation Lock, with per-unit identifiers |
| Quantity and evidence | Minimum order, permitted mixed lots, inspection results and evidence supplied before shipment |
| Total order cost | Currency, unit price, freight and insurance inclusion; identify destination charges separately |
| Commercial terms | Payment stages, dispatch timing, risk transfer, warranty and dispute process |
BiteLot’s grading standard, inspection process, model-code guide and ordering terms describe the checks and terms to use in a request.
Read price differences before choosing
A lower unit price may accompany a different battery threshold, version, quantity or freight arrangement. Ask the supplier to identify each changed field. If the specifications are different, treat the offers as alternatives rather than evidence that the market price has fallen.
If the same specification costs less in a later dated quote, that establishes a difference between those offers. It does not establish a market-wide trend. Keep both versions and confirm the actual lot and expiry before payment.
Send a request that can be quoted
Include the exact models, capacities, condition and battery requirements, quantities, destination and SIM needs. Mark acceptable alternatives explicitly. Request the quote date, validity and freight scope in the reply so you can compare the total order on the same basis.
