"Refurbished" means very little on its own. The grade attached to it means everything. Here's what cosmetic and functional grades actually describe — and what to check before you buy or sell at volume.
Cosmetic grade vs. functional grade
Every credible refurbisher scores a device on two independent axes. Cosmetic grade describes how it looks — scratches, scuffs, screen wear. Functional grade describes how it works — whether the battery, cameras, sensors, radios and ports all pass test. A device can be cosmetically flawless and functionally broken, or vice versa, so the two are always assessed separately.
The cosmetic scale: A, B, C, D
- Grade A — excellent. Little to no visible wear; looks close to new under normal light.
- Grade B — good. Light, visible signs of use — minor scratches or scuffs, nothing structural.
- Grade C — fair. Clearly used, with deeper marks or visible wear, fully functional.
- Grade D — heavy wear or cosmetic damage; usually priced for budget channels or earmarked for parts.
Some operators add a "Grade A+" or "like new" tier above A. The labels matter less than the written criteria behind them — which is why consistency, not vocabulary, is the real differentiator.
Why functional grading is the part that bites
Cosmetic disputes are annoying; functional ones cost you returns and reviews. A proper functional grade comes from a documented test pass — battery health percentage, display and touch, front and rear cameras, Face/Touch ID and sensors, speakers and mics, Wi-Fi and cellular, charging and ports. At De Novo, every unit runs through 70+ functional checkpoints before it's graded.
The same grade should mean the same thing on unit one and unit ten thousand. If it doesn't, it isn't a grade — it's a guess.
Five questions to ask any refurbisher
- Are cosmetic and functional grades scored separately, and documented per device?
- What's the minimum battery health for each grade?
- Is data erasure certified, with a per-device certificate?
- Can you trace a grade back to a serial number and its test results?
- How are grade overrides logged and audited?
If the answers are vague, the grade is decorative. If they're specific and traceable, you can build a business on it.
