How the software support score is calculated
The maker's published update promise: promised years of os upgrades (55%, required), promised years of security updates (45%, required).
Based on the maker's published update policy at launch.
| Input | Weight | Required | Scale: value → points |
|---|---|---|---|
| Promised years of OS upgrades | 55% | yes | 0 years → 0 · 1 years → 15 · 2 years → 35 · 4 years → 70 · 6 years → 90 · 7 years → 100 |
| Promised years of security updates | 45% | yes | 0 years → 0 · 2 years → 25 · 4 years → 55 · 6 years → 85 · 7 years → 100 |
Worked example
The Google Pixel 11 Pro XL is #3 in the current software support list. Its software support score of 100 comes from these inputs:
| Input | This phone | Points | Weight | Contribution |
|---|---|---|---|---|
| Promised years of OS upgrades | 7 years of OS upgrades | 100 | 55% | 55.0 |
| Promised years of security updates | 7 years of security updates | 100 | 45% | 45.0 |
The contributions add up to the score. An input that is not confirmed is left out and the remaining weights are scaled up to 100%, except where the category counts an unknown input at the middle of its scale (shown as "counts as 50").
