A clean listing photo of a used iPhone 15 cannot establish the condition of the unit you receive. What matters is whether you can activate it, use it reliably and understand any previous repairs. Apple publishes guidance for buying a used iPhone. Here is a practical order for those checks at delivery or in-store.
1. Confirm you can use the phone before judging its finish
If the phone shows “iPhone Locked to Owner” during setup, ask the seller to remove Activation Lock before proceeding. Apple advises against buying a phone in that state. A Hello screen shows the device was erased, but you still need to complete activation to confirm that your own account can use it.
For an online order, learn the return window and the process if activation fails. Do not exchange this check for a promise that a password or unlock will arrive later. Ownership-related steps must be completed by the legitimate owner.
2. Review parts history and battery context
Open Settings > General > About to look for Parts and Service History. Apple distinguishes “Genuine Apple Part” from “Unknown” labels; a tidy exterior does not prove that nothing was replaced. Ask what was repaired and request documentation when available.
Then check Settings > Battery > Battery Health & Charging for maximum capacity and important messages. A percentage alone does not promise all-day endurance. Consider the phone’s age, service messages and asking price together rather than applying one supposedly perfect battery threshold to every purchase.
3. Test the features you actually use
Take photos in bright and dim light with the main and Ultra Wide cameras; record a short video and play back its sound. Test Face ID, earpiece and loudspeaker, Voice Memos, Wi-Fi, volume buttons and the Ring/Silent switch. Connect a USB-C cable for charging and connection; the shared connector does not give the standard iPhone 15 the Pro model’s USB 3 speed.
Inspect the display on light and dark backgrounds for discolouration or dead areas and test touch near the edges. If a feature cannot be tested at handover, document that with the seller and understand the post-delivery inspection window. A model stock image is not proof of the exact used unit’s condition.
4. Inspect the body and SIM compatibility
Remove the case, if present, to inspect the frame, back, camera area and charging port. Light scratches differ from dents or gaps. Water resistance can diminish with wear or repairs, so do not test a used phone by submerging it. Apple also explains how to check Carrier Lock under Settings > General > About.
If you need a physical SIM, eSIM or travel connectivity, confirm the exact device variant before buying. Regional configurations can differ; ask for the specifications of the unit being delivered, not only the generic “iPhone 15” model name.
5. Compare the actual unit and its return terms
Match capacity, colour, battery condition, parts history and included accessories to the price of that exact configuration. A lower-priced unit needing an early battery replacement or having an unverified feature may not save money. For an online order, retain the listing description and read the current returns policy before payment.
The used iPhone 15 at TECHBUY page shows the listed options and live pricing when you visit. If you are considering Pro, our iPhone 15 versus 15 Pro guide handles display and camera trade-offs separately from this condition checklist.
Conclusion
Use this order: activation rights, parts history, battery, functions, then appearance and price. No guide replaces inspecting the exact unit you receive. Sources: Apple’s preowned iPhone guidance and Parts and Service History.
