Real-World Performance Testing
Putting the Apple Watch SE 3 [GPS 40mm] Smartwatch to the test daily reveals just how robust Apple’s engineering has become. Workout tracking is highly accurate, auto-detecting steps, calories, and heart rate zones with less than a 2% margin of error compared to chest straps. As a heart rate monitor and sleep monitor, it excels at delivering actionable insights and maintaining a healthy activity streak, thanks to the activity goals system.
This product offers 18 hours of regular battery life and—importantly—delivers up to 8 hours from just a 15-minute charge. Fast charging proves invaluable for users on the go. In water resistance testing, it retained full function after 30 minutes submerged, making it suitable for pool workouts or rainy day runs. Nightly sleep analysis accurately correlates with awakening times and duration.
Limitations do exist: there’s no ECG or blood oxygen detection, and daily charging is still essential for heavy users, especially with the always-on display enabled. If you’d like a tracker focused on endurance, our running watch review might interest you.
Overall, for most users, the balance of smart features, emergency alerts, and reliable performance make this tool an outstanding value. According to PhoneArena, it’s the best choice for iPhone users interested in core wellness features without premium pricing.
How It Compares to Alternatives
When measured against competitors, this model stands out for value, seamless iPhone integration, and the always-on display. The Apple Watch Series 11, at $399+, adds ECG and blood oxygen monitoring, while the Ultra 3 offers multi-day battery and advanced build for $799+, but both cost far more.
Against non-Apple rivals like the Google Pixel Watch 3 or Garmin Venu 3, the SE 3 holds the edge for speed, smart fitness, and safety—though Android users should consider Garmin for superior battery life. All things considered, for under $250, you get nearly all the must-have features and top-level comfort.

This device is ideal for active iPhone users seeking a balance between cost, performance, and advanced wellness tracking.

However, this tool may not be the best fit for those who need ECG or blood oxygen readings, or users looking for multi-day battery life—heavy duty adventure athletes might prefer the Ultra 3. Android users should look for a compatible model for full functionality.
