What Are Refurbished Grades?

At CellShark, we believe buying a refurbished iPhone should be a transparent and simple experience. To help you choose the device that best fits your needs and budget, we use clear cosmetic grades for our smartphones.

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 across several key areas to determine its grade:

  • Cosmetic condition, such as scratches, dents, or signs of wear on the body
  • 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 cosmetic wear, such as very fine surface scratches on the screen or frame, which are barely noticeable during normal use. Every device is fully functional, professionally tested, unlocked, and equipped with a dependable battery above 85% battery health. This condition offers a great balance between minor savings and near-perfect appearance.

Good Condition

Visibly Used

Good condition iPhones show more visible signs of use, including noticeable scratches or minor dents on the frame and back cover, which can be easily hidden with a phone case. The screen remains intact with normal cosmetic scratches that do not affect readability or use. Every device is fully functional, professionally tested, unlocked, and equipped with a reliable battery above 80% battery health. This condition is ideal for customers who prioritize functionality and savings over cosmetic perfection.

Fair Condition

Budget-Friendly

Fair condition devices have noticeable cosmetic wear, including deeper scratches, scuffs, or dents on the frame and screen. These marks are purely visual and do not affect the functionality of the device. Every Fair iPhone is fully functional, professionally tested, unlocked, and has a reliable battery above 80% battery health. This condition offers the maximum possible savings, making it perfect for budget-conscious buyers who want a fully working device at the lowest price.
