Amazfit sells both the Active 3 Premium and the Balance 2 as fitness-focused smartwatches built on the same ZeppOS platform with many overlapping features. But the two watches target different buyers, and make very different design trade-offs.
Choosing between them comes down to three questions:
- How seriously do you run?
- How much do you value battery life and a larger screen?
- Does the extra $130 actually buy features you will use?
This comparison answers all three.
The best overall smartwatch in this comparison thanks to its 21-day battery life, dual-band GPS, larger display, and broader multi-sport features. If you want the most capable watch for everyday use, the Balance 2 is the strongest option.

Design and Wearability
The Active 3 Premium uses stainless steel, which is denser and more scratch-resistant than aluminum. This is unusual at the $170 price point.
The Balance 2 earns a military-grade durability rating and offers 10 ATM water resistance, meaning it can support scuba diving while the Active 3 Premium cannot.
Despite the larger case size, the Balance 2 is lighter at 42 g, compared with 54.6 g for the Active 3 Premium.
The control schemes also differ.
Active 3 Premium
- four physical buttons
- ideal for cold weather training
Balance 2
- rotating crown + single button
- more lifestyle-oriented interface
Display
The Active 3 Premium surprisingly wins here.
Its 3,000-nit brightness makes it easier to read in direct sunlight.
The Balance 2 counters with a larger 1.5-inch display, which is better for reading notifications and navigating menus.
Outdoor athletes may prefer the brighter Active 3 screen.
Battery Life
Battery endurance is where the Balance 2 pulls clearly ahead.
Balance 2
- 21 days typical use
- ~14 days heavy use
Active 3 Premium
- 12–13 days typical use
For travel, hiking, or multi-day activities, the Balance 2 is significantly more convenient.
GPS Accuracy
The Balance 2 uses dual-band GNSS, which reduces signal reflection errors in cities or forests.
Testing by reviewers has shown it performs close to Garmin devices in many conditions.
The Active 3 Premium uses single-band GNSS across six satellite systems. This is still accurate for most road running but cannot fully match dual-frequency tracking.
Running Features
This is where the Active 3 Premium shines.
It includes:
- Running power
- Lactate threshold estimation
- Ground contact time
- Posture monitoring
- Rhythm analysis
The Balance 2 does not include these metrics.
The Active 3 Premium also integrates with:
- TrainingPeaks
- Runna
- Intervals.icu
- Strava
For runners following structured training plans, the Active 3 Premium offers deeper coaching tools.
Multi-Sport and Lifestyle Features
The Balance 2 is the broader smartwatch.
It adds:
- HYROX competition modes
- scuba diving support
- golf maps for 40,000 courses
- AI food logging
- 32 GB storage
- NFC payments
These features make it far more versatile outside of running.
Who Should Buy the Active 3 Premium
Choose the Active 3 Premium if:
- running is your main sport
- you follow structured training plans
- you want lactate threshold and running power metrics
- you want maximum training data for the lowest price
It delivers serious running tools for $130 less than the Balance 2.
Who Should Buy the Balance 2
Choose the Balance 2 if:
- you do multiple sports
- you want a premium everyday smartwatch
- battery life matters more than advanced running metrics
- you want scuba, golf, and lifestyle features
It is the better all-around smartwatch.
Bottom Line
The Active 3 Premium is the better watch for runners.
The Balance 2 is the better everyday smartwatch.
If you follow structured training plans and want to improve your running performance, buy the Active 3 Premium.
If you want a smartwatch that handles fitness, lifestyle, travel, and multi-sport activities with a three-week battery, the Balance 2 justifies its higher price.
