These three terms get used loosely — sometimes interchangeably — by sellers, but they mean different things, and the difference affects both price and how much risk you're taking on.
Refurbished
A refurbished iPhone has gone through a formal inspection and repair process: diagnostics, replacement of worn parts (commonly the battery), cosmetic cleanup, a factory data wipe, and functional testing before resale. The seller stands behind that process, usually with:
- A grading system (like "Excellent," "Good," "Fair") describing cosmetic condition
- A warranty, typically 90 days to 1 year depending on the seller
- A stated battery health minimum
Apple's own Certified Refurbished program is the gold standard here — units come with a new battery and outer shell, a full one-year warranty, and the same accessories as a new purchase, usually at 10–15% off retail. Third-party refurbishers (Back Market, Gazelle, Decluttr, and similar) are typically cheaper but vary more in quality — check their specific grading and warranty terms.
Used
A used iPhone is sold as-is by an individual or a marketplace like eBay, Craigslist, or Facebook Marketplace, with no guaranteed inspection or repair process. What you see is what you get — the seller may or may not disclose battery health, screen condition, or repair history accurately. Prices are usually the lowest of the three categories, but so is your protection if something's wrong.
If you go this route: insist on the seller showing you Settings → Battery → Battery Health live (see our full guide to checking battery health for what the numbers mean), confirm carrier-lock status with the seller before paying, check the device's warranty status through Apple's Check Coverage tool, and use a payment method with buyer protection.
Open-Box
An open-box iPhone is technically new — it was purchased, then returned unused or barely used, often because the buyer changed their mind rather than because anything was wrong with it. Retailers resell these at a discount even though the phone itself has full or nearly full battery health and no wear. Open-box is usually the best value of the three if you can find it, since you're getting near-new condition without near-new pricing — but availability is inconsistent since it depends entirely on what gets returned.
Quick comparison
| Inspection Process | Typical Warranty | Battery Condition | Price vs. New | |
|---|---|---|---|---|
| Refurbished | Yes, formal | 90 days–1 year | Often replaced | 20–40% off |
| Used | No | None (marketplace-dependent) | Unknown/unverified | 30–50% off |
| Open-Box | Minimal (returns check) | Often full original warranty | Near-new | 10–20% off |
The right choice comes down to how much you value certainty versus price. If you want the lowest possible cost and are comfortable doing your own verification, used marketplaces can work. If you want a guarantee behind what you're buying, refurbished — ideally Apple Certified or a reputable third party — is the safer bet.
