Amazfit Active 3 Premium vs COROS PACE 4: which should you buy?
Get the COROS PACE 4. It is the stronger watch for long days outdoors, and it works fully with an iPhone, where the Amazfit Active 3 Premium works with limits. For a runner who is out for hours, the PACE 4's battery and training tools are the reason to spend a little more.
Who should get the COROS PACE 4
Get the PACE 4 if running is the point. COROS lists up to 41 hours of GPS and 19 days of daily use, with threshold pace, race estimates, training load and recovery built in. It works fully with an iPhone and with an Android phone, which matters if you use an iPhone.
Who should get the Amazfit Active 3 Premium
Get the Active 3 Premium if you want a light everyday watch that takes running seriously. Amazfit gives it built-in running workouts, coached plans from a 5K to a marathon, and running power, plus heart rate, blood oxygen, skin temperature and sleep tracking with no subscription. It also carries free offline maps with turn-by-turn directions. On an iPhone it works with limits, so some features that need deeper phone access stay on Android.
The differences that matter
The Active 3 Premium is ahead on heart rate and sleep tracking, and it adds offline maps with directions. If sleep is what you most want to track, that matters.
The PACE 4 is the runner's tool. Its race estimates and recovery stats tell you how hard to go, and its battery lasts through long training weeks without a charge.
