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 PTA Mobile Tax and DIRBS Registration Work
Understand IMEI registration, device valuation and why unofficial PTA-tax estimates can differ from the PSID amount.
Read the complete guide →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 × 30% + physical-condition score × 25% + verification score × 45%.
Applies the displayed mathematical relationship directly to the values entered. Users should verify units and any institution-specific interpretation.
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.
How to interpret your result
Create a simple used-phone risk score from battery health, physical condition and verification checks. Read the main result together with the supporting values rather than treating one number as a guarantee. The disclosed method is: Inspection score = battery health × 30% + physical-condition score × 25% + verification score × 45%.
Input guide
Check battery health using device diagnostics where available.
Rate physical condition only after inspecting the frame, display, ports and cameras.
Use verification completeness for IMEI, PTA, ownership, account locks and functional tests.
Scenario comparison
| Scenario | What it demonstrates |
|---|---|
| Worked baseline | Battery health of 85, physical condition of 80 and verification completeness of 100 produce an inspection score of 91 out of 100. |
| Hidden repairs check | Water damage or non-original parts may not be visible externally. |
| Identity checks stress test | IMEI status and ownership evidence require direct official or documentary verification. |
Common mistakes to avoid
- Ignoring hidden repairs: Water damage or non-original parts may not be visible externally.
- Overlooking identity checks: IMEI status and ownership evidence require direct official or documentary verification.
- Failing to test test duration: Intermittent faults may not appear during a brief meeting.
Confirm current price, specifications, warranty and approval status directly before purchasing a phone.
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.
