Used Smartphone Buyer's Checklist: How to Inspect a Phone Before You Pay

Complete checklist for inspecting a used smartphone in person: screen, battery, IMEI, Face ID, cameras, and more. 10 minutes that can save you hundreds.

Most bad used-phone purchases share one thing in common: the buyer was rushed. Ten calm minutes of inspection at the meetup will either confirm quality or save you from an expensive mistake. Save or print this checklist before you go.

πŸ’‘ BEFORE THE MEETUP

Ask the seller for the IMEI in advance (dial *#06# or find it in Settings). Check it via the manufacturer's website or a reputable IMEI checker. Takes 2 minutes and can save hundreds of dollars.

1. Physical inspection

2. Software checks

🚩 WALK AWAY IF

The seller won't let you into Settings, rushes you, says "everything is fine, no need to check," or claims the iCloud account "can't be signed out right now". These phrases mean the phone is stolen or locked.

3. Battery β€” the most important check

Battery replacement costs $50–120. Sellers often omit poor battery health.

4. Full function test (10 minutes)

πŸ“Œ NEGOTIATION TIP

Found a defect during inspection? State the repair cost and ask for exactly that discount. Most sellers agree β€” it's fair and specific.
