Compare Apple Watch SE 3 vs Amazfit Active 3 Premium

Reviewers found automatic workout or walk detection useful and generally dependable, though one noted occasional slower workout-end recognition.

Workout auto-detection is mixed: some sources say it auto-recognizes strength movements and several sports, while one hands-on review says it lacks automatic workout detection.

The app ecosystem is a major strength, with reviewers praising the Apple Watch App Store and broad app availability compared with rival budget watches.

The app ecosystem is useful but bounded: reviewers mention hundreds of apps and Zepp App Store extras, while one notes apps must come from Zepp rather than Apple or Google stores.

Band support is a strength because the SE 3 uses Apple’s familiar strap system and has many Apple and third-party options.

Band impressions are generally practical, with standard 20 mm quick-release or non-proprietary bands and an included silicone strap.

Battery life is the clearest mixed area: some reviewers saw all-day or better results, while others still treated it as a daily-charge watch.

Battery life is one of the strongest themes, with typical use ranging from about 8-12 days in hands-on reviews and up to 24 hours in GPS mode in launch coverage.

Blood oxygen tracking is consistently described as missing from the SE 3, making it a clear limitation versus Series and Ultra models.
