Behind the comparison

How we compare products

We bring product facts together so you can understand the differences and decide what matters to you. Here’s where those facts come from and how to read our comparisons.

Where the facts come from

We use manufacturer specifications and product documents, with links to the evidence. Check the exact model, region and configuration: two products with similar names can differ.

You can check the source. Open the information controls beside a specification to see its source and any measurement conditions.
Missing information stays visible. “Unknown” or “Not provided” means we haven’t verified a value. It does not mean the product lacks that feature.
Claims need context. Manufacturers can measure brightness, battery life and speed differently. We keep those limitations alongside the figures.

These comparisons use published evidence. We have not independently lab-tested the products shown here.

What a match score means

Our phone comparisons can show a personalised match score from the available specifications. Give a category more importance and it contributes more to your result.

For example

If camera features matter more to you than display features, increasing the camera priority gives those features more influence. Someone with different priorities may get a different recommendation.

The score helps compare published capabilities. It does not measure real-world photo quality, comfort or your experience using a product. A higher score is not a promise that you will prefer it.

When different specifications hit the same scoring limit, we withhold the overall and score-per-price verdict. Equal model scores do not establish equal products.
The feature comparison also shows hardware and capabilities outside the formula. Small physical differences remain separate from the main capability changes.
If a category you select lacks comparable evidence, we show that a score or recommendation is unavailable.
Must-haves are checked separately. You can see a missed requirement or an unverified feature without hidden point deductions.
Other product categories use their own relevant facts and feature checks. The phone scoring formulas below do not apply to every product on the site.

How we compare prices

Always check which price a comparison uses. A manufacturer’s recommended price is a reference price. Retailer search links let you check offers; they do not confirm a current price.

Where a phone comparison shows an equivalent price, it estimates the price at which both phones would offer the same match score per pound. It uses your priorities and the prices shown in that comparison. It does not predict a discount or tell every buyer what to spend.

Confirm the exact model, final price and delivery cost with the retailer before buying.

Technical details Phone scoring formulas and weights

Phone scoring formula · version 1.0.0. Recommendation safeguards updated 10 September 2026.

Each numeric input is scaled to a 0–100 score and limited to that range before its weight is applied. The caps below stop an individual specification contributing without limit.

Category formulas

Display

Evidence confidence: Medium

40% published peak brightness (capped at 3,000 nits) + 35% pixel density (scaled from 300–500 ppi) + 25% maximum adaptive refresh rate (capped at 120Hz).

Peak-brightness figures can use different manufacturer test windows and are not treated as independent measurements.

Camera capability

Evidence confidence: Medium

25% native telephoto reach (capped at 5x) + 15% optical-quality reach (capped at 10x) + 35% published pro workflows (four-item ceiling: Log, RAW, external recording and genlock) + 5% 8K availability + 20% native rear-camera count (capped at four).

This measures published hardware and workflow coverage. Frame-rate modes are excluded because manufacturers classify normal and slow-motion capture differently. It does not claim to measure photo or video quality.

Battery claims

Evidence confidence: Low cross-brand

65% claimed local-video duration (capped at 35 hours) + 35% claimed charge percentage per minute (capped at 2.5).

Both inputs are manufacturer up-to claims. Different test protocols make the resulting cross-brand score provisional.

Performance

Evidence confidence: Unavailable

No score until comparable CPU, GPU and sustained-load results exist under a shared independent protocol.

Chip names and generation-over-generation marketing percentages are deliberately insufficient.

Longevity

Evidence confidence: Evidence-dependent

Published model-specific software-support duration, normalized against a seven-year ceiling.

A brand’s historical behaviour is not converted into a guarantee. Missing fixed commitments remain unknown.

Personal match calculation

match = Σ(priority × category score) ÷ Σ(priority)

Priorities range from Ignore (0) to Critical (3). A selected category without a score makes the overall score unavailable. If all priorities are set to Ignore, equal category weights are restored. Must-haves are evaluated separately.

Equivalent price calculation

equivalent price(B) = price(A) × score(B) ÷ score(A)

This compares score per unit of the same currency. It needs available scores from the same scoring method; an equivalent price is unavailable when the reference score is zero.

First calculated 4 September 2026. Changes to the scoring rules receive a new version so results remain traceable.
