Frequently asked
What buyers want to know.
How long does the battery really last?
Reviewers say this watch lasts about 30 days on a full charge, far longer than typical smartwatches like the Apple Watch which last roughly a day. Buyers rate battery life highest at 4.8 out of 5.
What health features does it have?
The ScanWatch 3 tracks heart rate, ECG, blood oxygen levels, breathing disturbances, and sleep. Buyers rate health monitoring features at 4.9 out of 5, and this is the first Withings watch to be FDA cleared for both its ECG and blood oxygen measurement capabilities.
Does it look like a smartwatch or a real watch?
