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.
