Frequently asked questions
Does Withings ScanWatch 2 write ECG data to Health Connect?+
ECG measurements and afib detection results are stored in Withings Health Mate and are not written to the standard Health Connect ECG data type. Steps, heart rate, sleep, SpO2, and workout sessions do write to Health Connect via Health Mate.
Does ScanWatch 2 write respiratory rate to Health Connect?+
Yes. ScanWatch 2 measures respiratory rate during sleep and writes it to the Respiratory Rate data type in Health Connect. FitMesh can display overnight respiratory rate trends alongside sleep stages and SpO2.
How long does ScanWatch 2 battery last and does it affect Health Connect sync?+
ScanWatch 2 has a 30-day battery life. Health Connect sync happens via the Withings Health Mate app on Android, which runs independently of watch battery status. As long as the watch syncs to the Health Mate app (via Bluetooth), the data flows to Health Connect.
