HRV is sleep HRV. Readiness is a daily wellness score. Note 3 requires enabling periodic HR/SpO2/stress and setting alert thresholds, with movement and fit restrictions. These are wellness functions. Sleep-breathing quality is not clinical sleep-apnea notification.3Owner's manualsupport.amazfit.com/us/amazfit_active_2(round)/files/user-manual.pdf.pdfRead 5 October 2026Printed pages 25-28 explain daily readiness from HR, stress, sleep, HRV and temperature, and explicit sleep stages including REM.

120min9Retailer pagerep.grupposme.net/RepAPRead 8 October 2026Public retailer-hosted original Amazfit Bip 6 Product Introduction V1.1 specification page. Battery table advertises Theoretical Charging Duration of 2 hours, converted exactly to 120 minutes as the nominal full-charge claim. The component is the watch: same table gives its 340 mAh battery and 14/6/26-day usage modes, with the original display/body specifications matching the official product. It is not an accessory charging time or a measured 0-100% test. Charger, device state, firmware, ambient temperature and endpoint protocol are not published. The retailer PDF export has no visible maker logo, so its provenance is classified as retailer rather than assumed direct manufacturer authorship.10Maker product pagein.amazfit.com/pages/faq/how-long-does-it-take-to-fully-charge-the-amazfit-bip-6Read 8 October 2026Amazfit regional storefront FAQ explicitly describes an approximate 1.5-2.5-hour full charge from empty. This is contextual corroboration for the nominal 2-hour product-introduction figure, not a measured result or a calculated midpoint. Conditions are not stated. The page footer identifies an AI Answer Engine, so the explicit specification-table figure remains the basis for 120 minutes.
