10 Best Long Battery Life Smartwatch 2025 in the United States

The Apple Watch Series 10 is a robust smartwatch that packs in a lot of features for health, fitness, and connectivity, but it falls short of expectations in the long-battery-life category. With a maximum battery life of up to 18 hours under normal use, it can extend to 36 hours in Low Power Mode. The fast charging feature is commendable, allowing the watch to reach 80% in about 30 minutes, which is convenient for quick top-ups but still requires frequent charging for all-day use.

The display is impressive, featuring an Always-On Retina display that’s bright and easy to read. Its health and fitness tracking capabilities are among the best in the market, providing advanced metrics, ECG functions, and comprehensive sleep tracking. This makes it a good option for those who are serious about monitoring their health. Another strength is its build quality. The watch is durable, water-resistant up to 50 meters, and dust-resistant (IP6X-certified), making it suitable for various activities, including swimming and outdoor sports. Its integration with the Apple ecosystem allows users to stay connected seamlessly, enjoying features like notifications and calls directly from their wrist.

Customization options are plentiful, allowing users to choose from various bands and watch faces, making it a stylish accessory. On the downside, users who are not already invested in Apple products may find it less appealing due to compatibility restrictions with iOS devices. Also, while the watch includes impressive features, the additional cost compared to other smartwatches may not justify the purchase for casual users.

While the Apple Watch Series 10 excels in health tracking and connectivity, its battery life may not meet the expectations of users looking for a long-lasting smartwatch, making it better suited for those who prioritize advanced features over extended battery performance.

The Garmin vívoactive 5 is an impressive smartwatch, especially if you're looking for long battery life. With up to 11 days of battery life in smartwatch mode, it's designed to go the distance without frequent charging. This is particularly beneficial for users with busy lifestyles who may not have time to charge their device regularly. The bright and colorful AMOLED display ensures readability and provides a vibrant user experience, though AMOLED screens can consume more power compared to other types of displays.

For usage patterns, the vívoactive 5 offers a wide array of health and fitness tracking features. From monitoring sleep and stress levels to providing personalized insights, it can be an invaluable tool for those who prioritize their health. Additionally, it includes over 30 built-in sports apps and even a wheelchair mode, making it versatile for various fitness journeys. The power-saving features are robust, with automatic nap detection and personalized energy monitoring (Body Battery) that help optimize usage and battery life.

The vívoactive 5 also supports music storage and wireless headphones, allowing for phone-free workouts, which adds to its practicality. One of the few drawbacks might be its higher power consumption due to the AMOLED display and extensive tracking features, but these are balanced by its comprehensive health and fitness capabilities. If you're looking for a smartwatch that combines long battery life, detailed health tracking, and a vibrant display, the Garmin vívoactive 5 is a strong contender.

The Samsung Galaxy Watch Ultra LTE is a robust and feature-packed smartwatch designed for those who lead an active lifestyle. Its durable titanium design ensures it can withstand tough conditions, including rain, dust, and even ocean swimming. One of its standout features is the exceptional battery life, making it ideal for long-term use without frequent charging. The display is a 47mm round touchscreen, which is responsive and provides clear visuals, essential for outdoor activities and fitness tracking.

This smartwatch excels in tracking various health and fitness metrics. It offers personalized insights through Galaxy AI, Energy Score, heart rate tracking, sleep monitoring, and wellness tips, helping users stay informed about their health and performance. The built-in GPS adds to its utility for outdoor exercises like running and biking.

Despite its many strengths, the Galaxy Watch Ultra LTE does have a few drawbacks. The charging time could be on the longer side, which might be inconvenient for users who need quick top-ups. Additionally, it operates on the Tizen OS, which may have fewer app options compared to other operating systems like Wear OS or watchOS. Nevertheless, if you're looking for a smartwatch that offers long battery life, comprehensive fitness tracking, and a rugged design, the Samsung Galaxy Watch Ultra LTE is a solid choice.
