Google Fitbit Sense 2 smartwatch, 6‑day battery ⌚

This Fitbit smartwatch focuses on continuous health monitoring and everyday convenience, combining stress detection, sleep analysis and built-in GPS for outdoor activity tracking. The Google Fitbit Sense 2 is aimed at users who want a compact wearable that supports guided mindfulness, heart rhythm checks and several days of battery life while remaining water resistant for swimming.

Key Points

The watch includes continuous electrodermal activity sensing for stress detection and presents a stress management score, along with on‑wrist tools for mindfulness and breathing exercises. Sleep tracking offers a personalised sleep profile, sleep stages and a sleep score, and there is a smart wake alarm and Do Not Disturb mode to keep nights undisturbed. Fitness features include more than 40 exercise modes, active zone minutes and integrated GPS to map runs and outdoor workouts without a phone.

Benefits

Heart health tools extend beyond basic tracking with an electrocardiogram app that can assess heart rhythm for signs of atrial fibrillation, and continuous heart rate monitoring supports daily activity analysis. SpO2 measurement and menstrual cycle tracking add breadth to the health data available in the companion app. The inclusion of six months of Fitbit Premium gives guided workouts, sleep and mindfulness content for users who want structured programmes and personalised insights. The slim design keeps the device unobtrusive during sleep and exercise, while smartphone call and message notifications bring practical telephony features to the wrist.

Usage Recommendations

For outdoor runners and cyclists, enable the integrated GPS for accurate route and pace recording. Use the sleep profile over several nights to let the algorithm adapt and deliver a more accurate sleep score. Consider activating EDA sessions during moments of stress to build a habit of short mindfulness breaks. Note that advanced features such as ECG and stress scoring rely on the companion app and may require permissions or updates in iOS or Android to function correctly, according to the manufacturer.

Practical Tips

Charge the device regularly to maintain the multi‑day battery duration, and use the included small and large bands to find the most comfortable fit for continuous monitoring. For swimming or showering, the 50 metre water resistance means you can keep the watch on during these activities, but consider rinsing and drying the strap after exposure to chlorine or salt water. Some features may behave differently depending on the paired smartphone platform and app settings, so check those options when you first set up the device.
