Functional Grading
Grading & Condition
Functional grading is the assessment of whether a used or refurbished device performs as expected across core hardware and software checks, independent of cosmetic appearance.
Functional grading evaluates operational performance such as battery health, charging, camera, display touch response, sensors, buttons, audio, connectivity, and biometric components. In recommerce workflows, a device can be cosmetically strong but functionally weak, or vice versa, so functional grading is assessed separately from aesthetic grading. Reliable functional grading reduces return rates, supports transparent buyer communication, and enables more accurate condition-based pricing and warranty decisions.
