How price order works

Lowest recorded store prices take priority over announced or launch prices, within the selected source market. Currencies use the dated EUR reference rates. Deposits and recurring charges are excluded from price order; missing prices stay last. Original price records remain visible.

Battery claims use different conditions and are not a controlled benchmark. “Not verified” is an evidence gap, not a missing feature. Prices are dated regional snapshots. Deposits, bundles and historical launch prices are labelled. Brightness measurement methods and battery workloads vary by manufacturer.
