What Are Refurbished Grades?

At CELLSHARK, we believe buying a refurbished iPhone should be simple, transparent, and trustworthy. That is why every device is carefully categorized into condition grades, helping you clearly understand the cosmetic condition, battery quality, and overall value before making your purchase.

Our grading system focuses mainly on the appearance of the device, while every iPhone remains fully functional, professionally tested, unlocked, and ready for everyday use.

How Are Our Grades Determined?

Each refurbished iPhone is professionally evaluated based on multiple important factors, including:

  • Cosmetic condition such as scratches, dents, and wear marks
  • Screen and frame appearance
  • Battery performance and battery health
  • Overall technical functionality
  • Previous usage history of the device
  • Results from our inspection and refurbishment process

Our Refurbished iPhone Conditions

Refurbished iPhone condition grades from Premium like new to Fair budget friendly
Premium Condition

Like New

Premium devices are the highest-quality refurbished iPhones available at CELLSHARK. These iPhones show no visible signs of use and are almost impossible to distinguish from a brand-new device. Every Premium iPhone is fully tested, unlocked, and equipped with original Apple parts, including an original Apple battery with battery health above 90%. This condition is ideal for customers who want the best refurbished experience with top cosmetic quality and excellent battery performance for intensive daily use.

Excellent Condition

Lightly Used

Excellent condition iPhones may show light signs of previous use, such as small scratches that are barely visible during normal use. Despite minor cosmetic wear, these devices are technically perfect and provide the same reliable performance as higher-grade models. Fully tested and unlocked, Excellent condition devices come with verified parts and reliable battery performance, making them a perfect balance between quality and value.

Good Condition

Visibly Used

Good condition iPhones show more visible signs of use such as scratches, scuffs, or small dents, but remain fully functional and dependable for everyday use. These devices are professionally tested, unlocked, and equipped with verified Apple parts to ensure reliable performance at a more affordable price. Good condition is an excellent option for customers who care more about functionality than cosmetic perfection.

Fair Condition

Budget Friendly

Fair condition devices have noticeable cosmetic wear from previous use, including visible scratches, dents, or marks. However, these iPhones are still fully functional, tested, and guaranteed to work properly. Equipped with verified Apple parts and dependable performance, Fair condition devices are ideal for customers looking for the lowest possible price while still enjoying the Apple experience.
