With each passing year, wearable tech gets better and better, and today, the Samsung Galaxy Watch 8 and Apple Watch Series 10 are among the best smartwatches for health monitoring in 2025. But if your utmost priority is accurate, thorough health monitoring, which one do you choose?

Below, we compare health tracking, battery, comfort, and ecosystem compatibility against one another to assist you in making the choice before your next upgrade or trade-in.

Key Features of Health Tracking Compared

Health Tracking Accuracy: What's Better?

Heart Rate & ECG

Both watches offer precise real-time heart rate monitoring and on-demand ECG tests for atrial fibrillation detection. Apple's sensors excel in workout coherence, while Samsung's new BioActive sensor delivers high-level recovery insights.

Sleep Monitoring

• Galaxy Watch 8 tracks sleeping phases, blood oxygen, and snoring with premium AI analysis for sleep advice.
  
  
• Apple Watch Series 10 focuses on sleep time, sleep phases, and respiratory rate, all charting nicely into the Apple Health app for a better understanding of health.
  
  

Samsung excels in snoring detection and customized coaching, while Apple excels in aggregation of ecosystem data.

Blood Pressure Monitoring

One of the strongest advantages of the Galaxy Watch 8 is its cuffless blood pressure monitoring (one-time calibration needed). The Apple Watch Series 10 is still lacking this capability, although there are rumors of potential future updates.

Skin Temperature & Cycle Tracking

Both models support skin temperature monitoring. Apple's integration of menstrual cycle tracking offers personal fertility information, whereas Samsung's Watch 8 includes temperature trends in its holistic health dashboard.

Battery Life for Health Tracking

• Galaxy Watch 8: Up to 2 days with Always-On Display turned off, 1.5 days with AOD enabled, depending on the intensity of health tracking.
  
  
• Apple Watch Series 10: About 18–24 hours of average usage, with Low Power mode extending to 36 hours but retaining fundamental health tracking capabilities.
  
  

Samsung offers better battery life, which means you are rid of the evening charging anxiety if you like to track sleep nightly.

Comfort and Compatibility

• Galaxy Watch 8: Most compatible with Samsung and Android smartphones, with round AMOLED display, slim fit, and multiple sizes.
  
  
• Apple Watch Series 10: iPhone-only, with best-in-class iOS integration, fitness rings, and Health app synergy.
  
  

Both are comfortable for 24/7 wear, but your smartphone ecosystem may select the best.
