Most people who sell their phone for cash focus on the model and storage size, treating condition as an afterthought. That’s a costly habit. Buyback platforms, trade-in programs, and individual buyers all use a standardized condition grading system, and where your device lands on that scale can make a dramatic difference to the final payout you receive.
This guide breaks down every condition grade you’ll encounter, explains exactly what evaluators look for, and gives you practical steps to protect your device’s position before you list it or submit it for a quote.
There is no single universal standard, different buyers use slightly different labels, but the industry has largely converged around four tiers. You’ll see them described as Grade A through Grade D, or as Like New, Good, Fair, and Poor/Faulty. The grading criteria are more detailed than most sellers realize, and even small cosmetic issues can push a device from one tier to the next.
| Grade | Common Label | Typical Value vs. Like New |
|---|---|---|
| A | Like New / Mint | 100% (baseline) |
| B | Good / Very Good | 70–85% |
| C | Fair / Acceptable | 40–60% |
| D | Poor / Faulty / Broken | 5–25% |
A Grade A device looks and functions as if it just came out of the box. The screen has no scratches, chips, or burn-in. The body has no dents, cracks, or significant scuffs. All buttons, ports, cameras, Face ID or fingerprint sensors, and speakers work without any fault. Battery health typically sits above 85%.
These phones often still have original packaging or accessories, although that is not always a hard requirement. Devices sold with original box and cable can attract an additional 5-10% on peer-to-peer platforms like Swappa or Facebook Marketplace, where buyers trust the provenance of the item.
This is the most common grade for phones that have seen regular daily use. A Grade B device is fully functional — every feature works — but shows minor cosmetic wear. Think light hairline scratches on the back glass, small scuffs on the aluminum frame, or micro-scratches visible only under direct light on the screen. None of this affects usability.
Battery health for Grade B devices generally falls between 80-85%. This matters more than most sellers expect. Research from The Tech Buyers indicates that phones with battery health above 80% can command 10–15% more than comparable devices with degraded batteries, because buyers factor in replacement cost and long-term usability.
A Fair-condition phone is functional but has visible damage that is hard to ignore. This could be a cracked back panel, moderate screen scratches, a small chip on a corner, or a noticeably worn finish. The device powers on, connects to cellular networks, and runs apps without software issues, but its cosmetic state makes it less desirable to secondhand buyers shopping for everyday use.
Grade C phones often end up with refurbishers rather than direct consumers. Refurbishment businesses purchase these devices at a discount, replace the screen or back glass, and resell them as Grade A or Grade B units, so there is still a healthy market for them. If you have a device in this condition, broken or cosmetically damaged phones can still carry meaningful value, especially on flagship models.
Grade D covers devices that are broken in ways that affect core functionality. A shattered screen that makes the display unreadable, a phone that won’t power on, water damage indicators triggered, a motherboard fault, or a camera that no longer works, all of these push a device into the Faulty category.
The drop-off in value here is steep. Data from SellCell’s 2026 Smartphone Depreciation Calculator shows that faulty Samsung phones are typically worth around 4.1% of their original retail price, and faulty Google Pixel devices often fetch just 1.8%. These are not typos, condition has that large an impact at the bottom of the scale.
That said, even broken devices are worth selling rather than discarding. Parts, IMEI value, and recycling programs all create a floor price that beats throwing the phone away.
The numbers are easier to understand with a real example. An iPhone 16 128GB has depreciated approximately 50.1% from its launch price when sold in Good (Grade B) condition, according to live depreciation data. Drop that same device into Fair condition, and you’re looking at a significantly lower offer, the gap between Grade B and Grade C on a $799 device can easily be $100–$150.
For Samsung, the contrast is sharper. SamMobile reports that most smartphones lose 20-30% of their value within the first year even in excellent condition. Add cosmetic damage or a functional fault on top of that baseline depreciation, and the payout can shrink considerably.
One pattern that shows up consistently across the resale market: unlocked phones in any condition sell for more than carrier-locked equivalents. If your device is still tied to a carrier, that alone may reduce your quote before condition is even factored in.
Knowing the checklist that buyback platforms use gives you a real advantage. Most grading assessments cover:
That last point is important. A phone in perfect physical condition that is still linked to a previous owner’s account will be graded non-functional by most professional buyers. Before submitting any device for a quote, it’s worth making sure the account lock is fully removed, steps for this vary by platform and operating system.
Yes — and the relationship is more nuanced than most people expect. Premium brands like Apple hold higher baseline resale values, which means the absolute dollar loss from cosmetic damage is larger on an iPhone than on a budget Android. But the percentage drop from Like New to Good is fairly consistent across brands.
Where brand matters most is at the faulty end of the scale. iPhones in non-functional condition still attract refurbishers and parts buyers at better rates than equivalent Android models, simply because the demand for genuine Apple components, screens, cameras, and battery assemblies, remains high across repair shops globally.
Sometimes, yes, and it is worth doing the math first. A professional screen replacement on an older iPhone might cost $80-$120 at a third-party repair shop. If that repair moves your device from Grade C to Grade B and adds $150 to your quote, the repair pays for itself. If the repair costs more than the grade difference, skip it and sell as-is.
For cosmetic improvements short of repair: a microfiber cloth to clean residue, removal of a screen protector that has deep scratches (the screen underneath is often cleaner), and a fresh case removed before photos — none of these cost anything and they improve first impressions on peer-to-peer platforms. For platform buybacks, the physical inspection is what counts, so staging photos matters less than the actual device state.
One more thing worth noting: common mistakes that lower your phone’s resale value often have nothing to do with physical damage. Missing accessories, forgotten account locks, and delayed selling timing — waiting too long after a new model launches, are factors that reduce your payout just as reliably as a cracked screen does.
Grade A (Like New) means the device shows no signs of use, no scratches, no scuffs, full battery health, all functions working. Grade B (Good) means the phone is fully functional but has minor cosmetic wear such as light hairline scratches on the body or frame. Grade A phones typically fetch 15-30% more than Grade B devices of the same model, depending on the platform.
Yes, significantly. A cracked screen that affects display visibility or touch function pushes a phone into the Faulty or Poor grade, which can reduce its resale value to as little as 5-25% of its like-new price. Even a cracked back glass without screen damage will usually drop the phone at least one full grade tier.
Battery health is one of the most scrutinized factors in the grading process. Devices with battery health at or above 80% are typically accepted into Good condition tiers. Phones with battery health below 80% may be downgraded or offered a lower quote because buyers factor in replacement cost. Phones with 80%+ battery health tend to earn 10–15% more at resale.
It depends on the repair cost versus the grade difference in dollar terms. If a screen repair costs $80 and moves your offer from $120 to $240, the repair is profitable. If the same repair only adds $50 to your quote, it is not. Always get a repair quote and a resale quote first, then compare the numbers before committing.
They can, if the device arrives in a different condition than what was self-reported during the initial quote. Most reputable platforms will give you the option to accept the revised price or have the phone returned. This is why accurate self-grading matters — overstating your phone’s condition wastes time for both parties and can affect trust ratings on peer-to-peer platforms.
Yes. Phones that no longer power on still have value as parts, for component harvesting, or through specialized buyers who accept non-functional devices. The payout is lower than a working device, but selling is still better than letting the phone sit in a drawer. Platforms that accept any-condition devices are designed specifically for this scenario.
Understanding how phone condition affects resale value is not just useful knowledge, it directly changes how much cash ends up in your pocket. Grading systems exist because buyers need a reliable shorthand to price used devices quickly, and learning to read those grades from the seller’s side gives you a real negotiating advantage. Whether your phone is in pristine shape or has seen better days, accurate grading, honest disclosure, and smart timing will always yield better results than guessing.
