The Used iPhone Inspection Checklist

Quick answer: Every used-iPhone horror story traces to a skipped check. The non-negotiables: watch the seller sign out of Find My in front of you (Activation Lock makes an iCloud-locked phone a paperweight — no exceptions, no 'I'll do it later'), check Battery Health in Settings, and verify the phone isn't carrier-financed or blacklisted (ask for the IMEI beforehand and check it). Then the hands-on twelve: screen genuineness warnings, True Tone presence, all cameras, Face ID enrollment, speakers and mics, charging port, buttons, and the parts-and-service history screen that modern iOS conveniently keeps for you. Fifteen minutes of checking beats months of regret.

★ BRING TO THE MEETUP

USB-C Cable + Power Bank

Test charging on YOUR gearA dead port hides behind 'it's just dead'

Sellers' cables can be chosen to mask a flaky port. Test charging with your own cable and power bank — solid connection, no wiggle games, charges immediately. It's also just handy if the phone arrives at 4%.

★ IF BATTERY WAS THE FLAW

Battery Replacement Path

Great phone + tired battery = negotiationFix costs less than the discount

A phone that passes everything but Battery Health is a negotiation opportunity, not a walk-away: price the battery service into your offer and you often land the best value on the page — a healthy phone below market.

🎯 Which Should You Buy?

Seller won't sign out of iCloud? → Walk away. Immediately. No story changes this
IMEI check shows finance/blacklist? → Walk away — that debt or flag follows the phone
Everything passes but battery? → Negotiate the battery service into the price
Parts history shows swapped screen? → Genuine-parts swap: fine at the right price; unknown parts: bigger discount or pass
Marketplace instead of in-person? → Same checks on arrival + the platform's return window is your meetup

Pro tip — do the Find My sign-out LAST, after everything else passes. Run the whole inspection with the phone still signed in — you need it functional for the tests anyway. Only after everything passes does the seller sign out of Find My, erase the phone in front of you, and hand over a factory-fresh device you watched become unlocked. That ordering also protects the seller's data — which honest sellers appreciate and scammers can't fake.

❓ Frequently Asked Questions

How do I check if a used iPhone is iCloud locked?

Have the seller open Settings — a signed-in Apple ID at the top means Activation Lock is active. They must sign out (Settings → their name → Sign Out) with their password, in front of you, before money moves. A phone erased but still activation-locked shows a lock screen asking for the previous owner's Apple ID.

What battery health should a used iPhone have?

85%+ is comfortable; 80% is the service-recommended line. Below that, price a battery replacement into your offer — it's a known, fixable cost on an otherwise good phone.

How do I check if an iPhone is stolen or blacklisted?

Get the IMEI (Settings → General → About, or the dial pad code *#06#) before meeting and run it through a carrier or reputable IMEI checker for blacklist and financing status. A financed phone can be blacklisted later when payments stop — that debt follows the device.

What does Parts and Service History show?

Modern iOS lists whether the battery, screen, camera and other components are genuine Apple parts, unknown parts, or service-replaced. An honest repair with genuine parts is fine; surprises in this screen are negotiation leverage or a red flag.
