Refurbished Phone Grades Decoded: What A, B & C Mean
Why Refurbished Phone Grades Are a Complete Mess
Buy a Grade A refurbished iPhone from one UK retailer and you might get a handset that looks genuinely mint. Buy a Grade A from another seller and you could unwrap something with a faint scratch across the back glass. Same label, completely different standard. Nobody's policing this.
Unlike food labelling or financial products, there's no UK-wide regulatory body setting rules for refurbished device grading. Each retailer - from big names like Back Market and musicMagpie to smaller independent resellers - writes their own definitions. That's fine when they're transparent about it. The problem is when they're not.
We see this constantly through our platform. Devices sold as one grade often arrive in a condition buyers associate with a lower one. And when those same devices eventually come back through OnRecycle to be resold or recycled, the grade they're assigned by our recycler network can be a full tier below what the original seller claimed. That gap costs people real money.
What Grade A, B and C Should Actually Mean
Let's start with what a reasonable, honest grading system looks like - because there is an emerging consensus, even if it's not enforced. Most reputable UK refurbishers broadly follow this structure, with some variation at the edges.
Grade A (or 'Excellent')
A Grade A device should be cosmetically near-perfect. Under normal lighting, at arm's length, you shouldn't be able to spot any scratches, scuffs or dents. Some sellers allow for microscopic hairline marks only visible under direct light at a specific angle - that's acceptable. What's not acceptable: visible scratches on the screen, chips to the frame or worn coating on the back.
Functionally, everything must work. Battery health is where things get interesting. A genuine Grade A phone should have a battery at 85% capacity or above - ideally 90%+. Some sellers push Grade A phones with batteries at 80%, which we'd argue is Grade B territory. Always check the small print.
Grade B (or 'Good')
Grade B devices have light but visible signs of use. You might see minor scratches on the back, light scuffing on the frame or the odd small mark on the screen - nothing that affects usability, but things you'd notice if you were looking. Think of it as a phone owned by someone who was reasonably careful but didn't use a case.
Battery health typically sits between 75% and 85% at this grade. All functions should still work perfectly. If a seller is listing a Grade B phone with any functional issues at all - a dodgy speaker, a temperamental charging port - that's not Grade B, that's Grade C at best, and arguably shouldn't be sold without full disclosure.
Grade C (or 'Fair' or 'Acceptable')
Grade C is the honest acknowledgement that a phone has lived a life. Expect noticeable scratches, possible deep scuffs on the frame and potentially some screen marks that are visible during normal use. The device should still function correctly - Grade C is a cosmetic category, not a functional one.
Battery health here can be 70-80%. Some sellers include a note that the battery may need replacing sooner rather than later, which is exactly the kind of transparency buyers deserve. If you're buying Grade C, you're trading looks for price - and the saving should be meaningful, not a fiver off Grade B.
What About 'Grade A+' or 'Like New'?
Some retailers have introduced a Grade A+ or 'Like New' tier above standard Grade A. In theory, this means the device is essentially indistinguishable from new - sometimes with original packaging, sometimes with original accessories. In practice, it's a marketing label as much as a technical one. A phone described as 'Like New' should ideally have battery health above 95% and zero cosmetic marks under any lighting condition. If a seller can't back that up with specifics, treat it as Grade A.
Questions to Ask Before You Buy Any Refurbished Phone
The grade label is a starting point, not a guarantee. Here are the specific questions worth asking - or at minimum, checking the product listing for - before handing over your money.
What is the exact battery health percentage? Not a range. Not 'good condition'. The actual number, ideally with a screenshot from the device's own battery health settings. Apple devices show this natively in Settings > Battery > Battery Health. Android devices vary, but reputable sellers will have tested this.
Has the device been network unlocked? A refurbished phone locked to EE or O2 is worth significantly less than an unlocked one - both to you as a buyer and later when you come to sell your phone through a recycling comparison site. Unlocked status is worth checking explicitly.
Are the parts original? This matters most for screens. A refurbished iPhone with a third-party replacement screen can trigger a 'non-genuine part' warning in iOS settings, and some recyclers in our network will grade it lower as a result. Ask whether any components have been replaced and, if so, whether they're OEM (original equipment manufacturer) parts.
What's the returns window? Under the Consumer Rights Act 2015, you have 30 days to return a faulty item bought from a UK retailer for a full refund. But 'faulty' has a legal definition - cosmetic disappointment doesn't always qualify if the listing described it accurately. A seller offering a 30-day no-quibble return on refurbished stock is giving you meaningful protection. A 14-day window with restocking fees is a red flag.
Is there a warranty? Twelve months is the minimum you should expect from a reputable UK refurbisher. Back Market offers a 12-month warranty as standard. Some sellers offer 24 months. Anything less than 12 months on a device above £150 should give you pause.
How Grades Directly Affect What You'll Get When You Recycle
Here's the bit most refurbished phone guides skip entirely: the grade you buy at affects the price you'll get later. And the gap is bigger than most people expect.
From the thousands of devices sold through our platform, we consistently see recyclers apply their own grading assessment when they receive a handset. Their grade - not the one it was sold to you under - determines your payout. A phone you bought as Grade A that has developed a few light scratches after a year of use will almost certainly be assessed as Grade B by a recycler. That's not unfair - it's accurate. But it means the resale value you're banking on might be lower than you planned.
Take a Samsung Galaxy S24 as a real example. On our network right now, a fully working Galaxy S24 in excellent cosmetic condition fetches meaningfully more than one with visible scratches. The difference between a recycler's 'working' and 'good' condition categories on a mid-range phone can easily be £20-40. On a higher-value device like an iPhone 16 Pro, the gap between top condition and 'good but scratched' can be £60-80 or more.
The practical takeaway: if you buy a Grade B phone at a discount, don't mentally price in a Grade A resale value two years later. Grade your future self's expectations alongside the phone itself.
Battery health compounds this further. Our recycler network - which includes companies like Gadget Reclaim, SellMyPhone.org and Vendi - will factor battery condition into their assessment. A phone with battery health below 80% at the point of recycling will attract lower offers, or the buyer will account for a replacement cost. Buy a Grade B phone with 76% battery health today and by the time you're ready to recycle it in 18 months, that battery will have degraded further. The maths matters.
The Brands Where Grades Matter Most
Not all phones are equal when it comes to how much grading affects value. Premium devices hold their value better, which means the difference between grades is amplified in cash terms.
iPhones are the clearest example. Our data shows Apple devices average around £255 across 258 models on our platform - and at the top end, an iPhone 17 Pro Max 1TB fetches up to £1,191. The spread between a pristine example and a scuffed one at that value level is substantial. If you're buying a refurbished iPhone 15 Pro or 16 Pro as an investment in future resale value, Grade A is worth paying for. The premium you pay upfront is likely to be recovered - or exceeded - when you come to recycle your iPhone later.
Samsung flagships follow a similar pattern. Google Pixel devices average around £163 across 73 models on our platform - respectable, but the depreciation curve is steeper than Apple, meaning the grade premium is harder to justify unless you're buying a recent Pixel 9 series device.
Budget and mid-range phones from brands like Xiaomi and OPPO average £62 and £57 respectively on our platform. At those price points, the cash difference between Grade A and Grade B is small enough that buying Grade B makes straightforward financial sense - especially if you're likely to upgrade again within 18 months.
How to Check a Refurbished Phone's Real Condition When It Arrives
The moment the box lands on your doorstep, run through this checklist before you do anything else. You have 30 days under consumer law, but the sooner you identify issues, the cleaner the return process.
Check the screen under bright, direct light at multiple angles - not just straight on. Scratches hide at oblique angles. Run your fingernail lightly across the surface; you'll feel micro-scratches before you see them clearly. Inspect the frame and back panel in the same way, paying particular attention to corners and edges where drop damage concentrates.
Then check battery health immediately - on iPhone via Settings > Battery > Battery Health & Charging, on Samsung via the built-in device care section or a free app like AccuBattery. If the battery health doesn't match what was advertised, that's grounds for a return, full stop.
Test every function: cameras front and back, speakers, microphone (use the voice memo app), charging port, Face ID or fingerprint sensor, all physical buttons and the SIM tray. A five-minute check on day one is worth far more than a three-week dispute later.
Finally, check the IMEI against a blacklist database - there are free tools online. A stolen or network-barred phone is worthless, and it'll be flagged immediately if you try to recycle it through a legitimate comparison site. This isn't paranoia; it's basic due diligence on any second-hand device.
