Quick Verdict
The Samsung Galaxy Watch 8 packs a full health sensor suite — ECG, blood oxygen, and blood pressure monitoring — into a sleek, Sapphire crystal-protected design, making it one of the most complete Android smartwatches available. It’s tightly integrated with Wear OS and Samsung Health, offering Galaxy AI features like Energy Score and running coaching. The trade-off is battery life, which typically lasts 1-2 days compared to the multi-day runtime of watches like the Garmin Vivoactive 6.

Frequently Asked Questions
Does the Samsung Galaxy Watch 8 work with iPhone?
No — the Galaxy Watch 8 runs Wear OS, which requires an Android phone. It works with any Android device, not just Samsung phones, but iPhone compatibility isn’t supported.
How accurate is the blood pressure monitoring feature?
It requires calibration with a traditional blood pressure cuff periodically to stay accurate, and Samsung positions it as a wellness-tracking tool rather than a medical-grade device. It’s useful for spotting trends, not a replacement for clinical measurement.
Is the battery life a dealbreaker compared to Garmin or Apple Watch?
The Samsung Galaxy Watch 8 stands out as the most complete Android smartwatch available, packing ECG, blood oxygen, and blood pressure monitoring into a genuinely refined, Sapphire-protected design. Deep Wear OS and Samsung Health integration make it feel purpose-built for daily use, and Galaxy AI features add real utility beyond basic tracking. Battery life won’t match Garmin’s multi-day runtime, but for Android users who want the most complete health picture on their wrist, this is the watch to beat.
Final Recommendation: Bythentic Pick
The Garmin Vivoactive 6 proves you don’t need a premium price tag for a genuinely capable smartwatch. Its 11-day battery life alone sets it apart from nearly every competitor, and the combination of a vibrant AMOLED display, 80+ sports apps, and full iPhone/Android compatibility makes it one of the most flexible fitness watches available. It skips ECG and blood oxygen sensors, but for buyers focused on everyday health tracking and serious battery life, that’s an easy trade-off.
