How we source data

MxMob is a specification database. The value of a database is entirely in whether you can trust the numbers in it, so this page sets out exactly how those numbers get here and what we do when we are not sure.

Where specifications come from

Every device record is compiled from primary sources, in this order of preference:

• Manufacturer specification pages. The official product page for the exact model and variant is always the first source consulted.
• Official press releases and newsroom posts published by the manufacturer at launch.
• Regulatory and certification filings — FCC, TENAA, BIS, NBTC and similar — which frequently confirm battery capacity, charging rates and radio bands before retail listings do.
• Carrier and retailer product listings for market-specific variants and pricing.
• Published benchmark database entries for performance figures.

Each device page lists the specific sources that record was built from, in the sidebar. If you want to check a figure yourself, the links are right there.

What we do with figures we cannot confirm

We leave them blank. A dash on a spec sheet is honest; a plausible-looking number that no manufacturer ever published is not. We do not infer specifications from a sibling model, we do not carry figures over from a predecessor, and we do not estimate to make a table look complete.

Every record carries an internal completeness score. Records that fall below our threshold are not published at all until enough of the sheet can be sourced.

How the data is compiled

Research and first-pass compilation are assisted by automated tooling that searches for and reads primary sources, then produces a structured record. That record is validated against a strict schema before it can enter the database: values must be the right type and in the right unit, and a record with no cited source is rejected outright.

The specification tables themselves are generated from the validated data by fixed rules, not written freehand. That is why every device page has the same categories, the same field labels and the same units — it is what makes comparisons between two devices meaningful rather than approximate.

Editorial assessments, verdicts and comparison analysis are written separately, based only on the verified specification sheet. They are original to MxMob. We do not reproduce or paraphrase other publications' reviews, and we do not claim to have physically tested devices we have not tested.

Provisional and unreleased devices

Devices marked Rumored or Announced have not reached retail. Their specifications are provisional and may change before launch. We mark them clearly rather than presenting them as settled fact.

Corrections

We get things wrong sometimes, and manufacturers occasionally revise specifications after launch. If you spot an error, tell us and include the source that shows the correct figure — contact us here. Corrections to specification data are made directly to the record, and the "last checked" date on the device page updates when they are.

Scope

The database currently covers 0 devices across0 manufacturers, with up to 150 specification fields per device. It grows as new devices launch.
