Editorial Policy
Accuracy is this site's entire reason to exist. Here is exactly how the data is sourced, verified, refreshed — and kept independent.
How we verify specifications
- Specs are collected from manufacturer documentation — never copied from other spec sites.
- Support windows come from each brand's official published policy, linked on every phone page with a visible “last verified” date.
- Where a manufacturer publishes no policy (Apple), we use its documented track record, label the window Our estimate everywhere it appears, and state the written legal minimum. Details in the methodology.
- If we can't verify a figure, we flag it or leave it out — we never guess silently.
How often data is updated
- Weekly: new phones are added to the database, with new comparisons.
- Monthly: street prices and update policies are re-verified; every ranking and “last updated” date refreshes from the data.
- Within days: when a brand changes an update policy or a major phone launches.
- Stale data gets fixed, not defended — corrections jump the queue.
Independence — rankings can't be bought
- Every ranking and verdict is computed from the database by the formulas on our methodology page — there is no editorial override to sell.
- We accept no payment, free devices, or other consideration for placement, scores, or coverage.
- Advertising (when present) is clearly separated from content and has no influence on results.
- All verdict copy is written by us, for this site; we don't publish sponsored content.
