Buying a used iPhone: grades A+, A, B, C mean looks — not function

Buying a used iPhone: grades A+, A, B, C mean looks — not function

A higher grade ≠ a better phone to use.
Grade C ≠ a broken phone.
This is anti-scam guide Issue 04 — after “check first, then read local prices” — not a push to check out.

After Issues 01–03: decode the grade letter

Issue 01 covered price, battery, locks, after-sales, then local bands. Issues 02–03 added screen/camera function checks and battery/locks in depth. This issue tackles the next confusion: what A+ / A / B / C actually mean — and how to skip vague “almost new” / “near A” talk.

One rule: grade ≠ function

On the used market, A+ / A / B / C should describe cosmetic condition — visible wear on screen glass, frame, back, and camera ring. It should not imply a better battery, stronger signal, or “more expensive = more usable.”

Solid practice: every listed unit passes the same functional checks and should be fully functional; the letter only says how used it looks. Battery health and locks belong in separate fields — not buried inside a fuzzy “great condition.”

How this series splits the work

Grade C can show more scratches; dead touch, a weak battery, or Find My still on must not be waved away as “grade is about the same.”

Four grades: where to look

Aligned with the public grades page (appearance first). Ask for the standard, then match the real unit. Check four zones on every grade: screen front, frame, back, camera ring.

Grade C ≠ broken: under a proper standard it still passes function checks; you save the cosmetics premium. Common entry budgets often sit on Grade C / B iPhone 13 / 14.

Floor rules: function checks are the same set across grades; battery ≥85% (when stated) is a battery item, not “higher grade = higher battery”; cracks / deforming dents / liquid damage sit outside normal grade language.

In person / on video: verify the claim

1. Ask standard + letter — “Public A+ / A / B / C? Which letter? What wear on screen and body?” Vague “looks great” = unclear.
2. Close-ups under side light / backlight — screen glass, four frame edges, back corners, camera ring. Far beauty shots hide scratches.
3. Remove case and film temporarily — thick cases hide knocks; refusal lowers trust.
4. Label vs unit mismatch → do not pay — labelled A / A+ but smashed corners + dense hard scratches + deeply scuffed ring → ask to re-label / re-price, or walk away.

Five traps

1. Made-up labels — “near A,” “A-,” “almost new” without a public chart. Ask which standard and letter. Even A+/A/B/C without a chart and wear notes are just four letters — not endorsement.
2. Hiding battery or locks behind grade — clean looks do not replace Maximum Capacity screenshots or Find My / Apple ID checks.
3. Treating C as “buyer beware only” — “issues are normal / no function guarantee” is risk-shifting, not grading.
4. Far / beauty photos only — no side-light close-ups, no case/film removal → not verified yet.
5. Packing function defects into a “grade discount” — “cheaper because Grade C” while touch is dead or Face ID fails. Grade gaps cover cosmetics only; run Issue 02 before negotiating.

Grades + local prices: worked example

Issue 01 noted: Grade C / B iPhone 13 / 14 often sit around HKD 1,800–3,500. Cleaner looks move toward A / A+ — typically a cosmetics premium of a few hundred HKD upward, not a function upgrade.

• High-grade price + unit that looks like C → pause (mislabelling or inflated grade).
• “A+” far below local rates with unclear wear/source → pause (Issue 01 “too low” logic).
• Fair C price, older looks, function / battery / locks pass → saving cosmetics premium, not gambling.

EUR figures differ; the method does not. For band examples, see Issue 01.

Before you pay

• [ ] Standard + which A+ / A / B / C letter stated
• [ ] Screen front under side light / backlight matches label
• [ ] Frame corners (case off if needed) match label
• [ ] Back scratch / dent density matches label
• [ ] Camera ring close-up — no high-grade / deep-scuff mismatch
• [ ] Film / case temporarily removed
• [ ] Quote roughly fits grade + local rates
• [ ] Grade not used to skip battery screenshot, Find My / account, after-sales
• [ ] Function spot-check (Issue 02)
• [ ] Clear mismatch → re-label / re-price or walk away — do not pay yet

“Certified” still means endorsement

A shop that stands behind the phone means less risk on you. Solid endorsement usually:

• Publishes A+ / A / B / C · separates looks from function
• 80+ checks · battery health ≥85% · real-unit photos
• 6-month warranty · 14-day returns
