Used iPhone Grades Explained: What A, AB, B and B/C Actually Mean

If you buy or sell used iPhones at scale, you already know that grades matter. However, the problem is that no universal standard exists across the industry. One supplier's Grade A is another supplier's Grade B. As a result, buyers get confused, disputes happen, and resellers spend more time managing expectations than moving stock. This guide explains what used iPhone grades actually mean, how to interpret them from any supplier, and how to communicate them clearly to your own customers.

Key takeaways

• Used iPhone grades describe cosmetic condition only. They do not cover battery health, functionality, or software status. Those are separate checks
• There is no universal grading standard across the industry. Each supplier defines grades differently, which is why a written grading guide from your supplier is non-negotiable
• The most common grades you will encounter are A+/A, AB, B, and B/C. Some suppliers also use C, D, and mixed-lot designations
• Choosing the right grade for your customers depends on their end use case, not just the price point
• At Refreshed Apples, every grade is precisely defined, published openly, and backed by a 60-point hardware and software inspection on every individual device

Why used iPhone grades exist

Used iPhones come from a wide range of sources. Some are trade-ins from mobile operators, some are corporate lease returns, some are insurance replacements, and others come from consumer buyback programmes. Consequently, the cosmetic condition of used iPhones varies enormously, even within the same model and storage configuration.

Grading exists to create a shorthand for that cosmetic variation. Instead of describing every scratch on every device individually, wholesalers and resellers use a letter or number grade to communicate condition quickly and consistently. In theory, this makes bulk purchasing faster and more reliable. In practice, it only works if both parties agree on what each grade means.

The problem with grading in the used iPhone market

Unlike, for example, diamond grading or credit ratings, used iPhone grading has no independent governing body and no enforced standard. Every supplier defines their own grades. Furthermore, some suppliers stretch their definitions to make stock look better than it is, particularly at the premium end where Grade A commands the highest prices.

Specifically, this means that buying Grade A from a supplier you have never worked with before carries real risk. The solution is simple but important: always ask for a written grading guide before placing a significant order with any new supplier. If they cannot produce one, that tells you something about how seriously they take quality control.

Used iPhone grades explained: what each one means

The following descriptions reflect the grading standard used at Refreshed Apples and are broadly representative of how reputable wholesalers across Europe define each grade. However, always verify with your specific supplier before assuming these definitions apply universally.

Grade A+/A (Pristine)

A+/A grade devices are in excellent cosmetic condition. In practice, this means only barely visible scratches that are difficult to see under normal lighting conditions. There are no cracks, chips, or significant marks on the screen or housing. The device looks close to new from a normal viewing distance.

For resellers, Grade A+/A is the right choice for customers who are buying the device as a gift, for customer-facing roles, or for any situation where appearance matters as much as functionality. It is also the right choice for businesses that want to present devices to employees as a quality investment. In short, appearance and perceived value matter at this grade level. Notably, Grade A+/A commands the highest wholesale price and typically the highest retail margin.

What to tell your customer: "This device has minimal signs of use. You would struggle to find a scratch without actively looking for one."

Grade AB (Great)

AB grade devices have light scratches on the screen and housing, along with minor scuffs. There are no cracks. Under normal use and at a normal viewing distance, the device looks good. However, under close inspection or in bright light, light scratches are visible on the glass and around the edges.

In terms of resale positioning, Grade AB is the most commercially versatile grade. It offers a meaningful price advantage over Grade A+/A while still presenting well to end buyers. As a result, it is the grade that moves fastest in most reseller catalogues and the one most B2B buyers default to for general employee device deployments.

What to tell your customer: "This device shows light signs of use. It looks good in day-to-day use but has some light scratches if you look closely."

Grade B (Good)

Grade B devices have moderate scratches on both the body and screen, with clear signs of use. There are no cracks. The device is fully functional but the cosmetic condition is noticeably used rather than lightly used. From a distance it looks fine. Up close, the wear is clear.

For resellers, Grade B is the right choice for buyers who prioritise functionality and price over appearance. Specifically, it suits buyers equipping field workers and warehouse teams. In these roles, devices go straight into a protective case and cosmetic condition is not a priority. It also suits markets where affordability is the primary driver and end buyers understand and accept the trade-off.

What to tell your customer: "This device works perfectly but shows clear signs of previous use. It is best suited to use in a case or for roles where appearance is not a priority."

Grade B/C (Fair)

B/C grade devices have heavy scratches and scuffs on both the screen and housing. They are fully functional and have no cracks, but the cosmetic condition reflects heavy previous use. Overall, these devices look worn.

In practice, Grade B/C suits buyers at the price-sensitive end of the market who need a working iPhone at the lowest possible cost. They are also popular in markets where devices are sold with screen protectors and cases as standard, effectively masking the cosmetic condition. Furthermore, Grade B/C devices are popular for parts, repair, and refurbishment businesses who will be replacing screens or housings anyway.

What to tell your customer: "This device is fully functional but shows heavy cosmetic wear. It is ideal for budget buyers or those who will fit a case and screen protector immediately."

APPLEASIS

APPLEASIS is a specific designation for devices that have been tested, inspected, and sealed by Apple directly, typically through Apple's own service and return processes. These are not graded in the traditional cosmetic sense. Instead, they are Apple-verified devices in mixed cosmetic condition, predominantly A+/A and AB grade.

Importantly, APPLEASIS devices come with a 30-day warranty covering iCloud and MDM issues but no cosmetic warranty, because cosmetic condition is mixed across the batch. For resellers, APPLEASIS offers the strongest possible hardware assurance at a price point that reflects the mixed cosmetic reality. Notably, Apple itself verified every unit.

What to tell your customer: "This device has been tested and certified by Apple itself. Cosmetic condition varies but hardware has been verified at the source."

What grades do NOT tell you

This is the section most buyers overlook, and it is worth reading carefully. A grade describes cosmetic condition only. It does not tell you anything about:

• Battery health: a Grade A device can have a degraded battery. Always ask your supplier for their minimum battery health guarantee. At Refreshed Apples, every device across every grade carries a battery health of 80% or above
• Functionality: a grade says nothing about whether the camera, speakers, Face ID, or charging port are working correctly. This is why independent hardware testing matters separately from grading
• Software status: a device could be graded AB and still have an active iCloud account, an MDM profile, or a blacklisted IMEI. Always confirm that devices are iCloud-free, MDM-free, and carry a Clean ESN before purchasing
• Original parts: some devices in the used market have had screens or components replaced with non-original parts. Ask your supplier whether they verify OEM parts status

In short, a grade from a reputable supplier is a meaningful signal. A grade from an unknown supplier without independent certification is just a label.

Which grade is right for which customer?

As a reseller, choosing the right grade for each customer segment is one of the most important decisions you make. Here is a straightforward framework:

• Retail consumers buying a personal device: Grade A+/A or AB. Appearance matters and these buyers will notice cosmetic flaws
• Corporate employees in office roles: Grade AB. Looks professional, priced sensibly for volume purchases
• Field workers, logistics, or warehouse teams: Grade B. Functionality matters, appearance does not. Devices will be in cases
• Education deployments: Grade AB or B depending on budget. Students are not typically precious about cosmetic condition
• Budget market or price-sensitive buyers: Grade B/C. Fully functional at the lowest entry price
• Repair and refurbishment businesses: Grade B/C or mixed lots. They are replacing components anyway

What to watch out for when a supplier's grading is vague

Unfortunately, not every supplier in the used iPhone wholesale market defines grades carefully. Here are the warning signs worth knowing:

First, watch out for suppliers who only offer two or three grades rather than a detailed scale. A supplier who grades everything as A, B, or C is almost certainly compressing a wide range of condition into too few categories. Second, be cautious of suppliers who cannot provide photos or video of a sample batch before purchase. A supplier confident in their grading will show you the stock. Third, ask specifically about battery health. If the answer is vague or the supplier cannot give you a minimum percentage, that is a red flag. Finally, ask whether testing is done in-house or through an independent platform. In-house testing with no third-party verification is the supplier grading their own homework.

How Refreshed Apples grades used iPhones

At Refreshed Apples, every device goes through a 60-point hardware and software inspection before it is graded and listed. We use Phonecheck for independent certification, which means every device has a verifiable test record that is not produced by us. Our grading system covers five tiers: A+/A, AB, B, B/C, and APPLEASIS, each defined precisely and published openly on our website.

Furthermore, every device we ship is data-wiped, iCloud-free, MDM-free, carrier-unlocked, and carries a minimum battery health of 80%. Our 30-day warranty covers functional defects and is extendable to 2 years. For resellers who need to stand behind the stock they sell to their own customers, knowing your supplier's grading is independently verified and precisely defined is not a nice-to-have. It is the foundation of your own reputation.

Frequently asked questions about used iPhone grades

What does Grade A mean on a used iPhone?
Grade A, also written as A+/A or Pristine, means the device has minimal cosmetic wear. Only barely visible scratches are present. There are no cracks, chips, or significant marks on the screen or housing.

What is the difference between Grade A and Grade AB?
Grade A devices have only barely visible scratches under close inspection. Grade AB devices have light scratches visible under normal conditions and minor scuffs on the housing. Both are good cosmetic conditions. However, Grade AB devices are priced lower and represent the most commercially popular grade in the wholesale market.

Is Grade B still worth buying?
Yes. Grade B devices are fully functional with no cracks. They show moderate cosmetic wear but perform identically to Grade A devices. For buyers prioritising value over appearance, Grade B is an excellent choice, particularly for field deployments or budget-conscious markets.

What does MDM-free mean?
MDM stands for Mobile Device Management. An MDM profile is software installed by a previous owner, typically a company, that can restrict or monitor the device. An MDM-free device has had all such profiles removed and can be fully configured by the new owner without restrictions.

What is a Clean ESN?
ESN stands for Electronic Serial Number. A Clean ESN means the device has not been reported lost, stolen, or unpaid on a carrier contract. A device without a Clean ESN may be blacklisted, meaning it cannot be activated on certain networks.

Does grading include battery health?
No. Grading describes cosmetic condition only. Battery health is a separate specification. Always ask your supplier for their minimum battery health guarantee before purchasing. At Refreshed Apples, every device across every grade carries a battery health of 80% or above.

What is APPLEASIS?
APPLEASIS refers to pre-owned devices that have been tested and sealed by Apple directly through Apple's own service and return processes. Cosmetic condition is mixed but predominantly A+/A and AB. Hardware has been verified by Apple.
