In our testing, it lasted over 36 hours with always-on display and regular GPS tracking. Enable low-power mode, and that extends to 72 hours, enough for multi-day adventures where charging isn’t convenient.
The precision GPS uses dual-frequency technology, providing the most accurate location tracking available in a consumer smartwatch. During trail runs through challenging terrain, the Ultra 2 maintained signal lock where other watches occasionally struggled.
The Action button is customizable and works with third-party apps, making it useful for quickly starting interval workouts or marking course checkpoints. The louder speaker makes it easier to hear workout prompts in noisy environments.
The price is steep at $799, and the larger case size may feel bulky on smaller wrists. However, for athletes who need the most durable Apple Watch with the best battery, nothing else comes close in the iOS ecosystem.
Pros: Best Apple Watch battery life, titanium case, precision GPS, 100m water resistance
Cons: Expensive, large size, limited appeal for non-athletes
Samsung’s Galaxy Watch 7 brings sophisticated health monitoring to Android users at a competitive price point. The BioActive sensor combination measures heart rate, blood oxygen, and body composition, providing a more complete picture of overall health than many competitors.
The sleep tracking features are worth mentioning. Samsung’s sleep analysis goes beyond basic stages to include sleep score, blood oxygen monitoring during sleep, and skin temperature measurements. The Energy Score feature helps you understand how well-rested you are each morning.
GPS performance has improved significantly over previous generations. Single-frequency GPS works well for most running and cycling activities, though the newer Galaxy Watch Ultra offers dual-frequency for more challenging environments.
One consideration is that Samsung’s health features work best when paired with Samsung phones. Some features may be limited or unavailable when used with other Android devices. The Wear OS platform offers good app support, though the selection isn’t as extensive as Apple’s watchOS.
