Strong inspection result
91 / 100
A score cannot reveal hidden repairs or prove ownershipHow this calculator helps
Turn three parts of a used-phone inspection into a consistent screening score. Battery health and physical condition matter, but identity, PTA, account-lock and functional verification receive the largest weight.
How to use it
- 1
Check battery health using device diagnostics where available.
- 2
Rate physical condition only after inspecting the frame, display, ports and cameras.
- 3
Use verification completeness for IMEI, PTA, ownership, account locks and functional tests.
Formula and methodology
Inspection score = battery health ร 30% + physical-condition score ร 25% + verification score ร 45%.
Worked calculation example
Battery health of 85, physical condition of 80 and verification completeness of 100 produce an inspection score of 91 out of 100.
What can affect the result?
Hidden repairs
Water damage or non-original parts may not be visible externally.
Identity checks
IMEI status and ownership evidence require direct official or documentary verification.
Test duration
Intermittent faults may not appear during a brief meeting.
Limits of this estimate
The weighted score cannot authenticate a device, detect hidden damage, verify legal ownership or replace official IMEI/PTA checks and professional inspection.
