Independent testing
How much independent testing exists for each smartphone
Of the 8 smartphones we track, 8 have been physically measured by at least one independent lab and 4 by three or more. Below is every one, ordered by how much independent hands-on evidence stands behind it — densest first.
A coverage record, not a ranking of which is best.
| Product | Independent labs | Metrics measured | Outlets on record |
|---|---|---|---|
| OnePlus 13 | 4 | 14 | 4 |
| Google Pixel 9 | 4 | 7 | 4 |
| Nothing Phone (3a) | 3 | 11 | 3 |
| Apple iPhone 16 Pro | 3 | 10 | 3 |
| Google Pixel 9 Pro | 2 | 9 | 2 |
| Apple iPhone 16 | 2 | 8 | 2 |
| Samsung Galaxy S25 | 2 | 7 | 2 |
| Samsung Galaxy S25 Ultra | 2 | 7 | 2 |
Each figure is a count of what independent testers actually did — how we count. A low count means little independent evidence has been gathered yet, never that a product is worse. See also the Smartphones buying guide and the reviewers we cite.
