Amazfit Active 2 VS Amazfit Balance 2

The most immediately felt difference between these two watches is physical size and wearability. The Amazfit Active 2 measures 43.9 × 43.9 mm and weighs just 29.5 g, while the Amazfit Balance 2 is noticeably larger at 47.4 × 47.4 mm and heavier at 43 g — nearly 50% more mass on the wrist. The Active 2 is also considerably slimmer at 9.9 mm versus 12.3 mm. In practice, this means the Active 2 will feel more discreet and comfortable for all-day or sleep tracking, and will suit smaller wrists far better. The Balance 2's bulk, by contrast, is a trade-off that typically comes with a larger display and expanded internal components.

On screen quality, the results are nuanced. Both use OLED/AMOLED panels with Always-On Display and sapphire glass — solid shared foundations. The Balance 2 wins on raw screen real estate with a 1.5″ display versus 1.32″, and its 480 × 480 px resolution technically exceeds the Active 2's 466 × 466 px. However, because the Active 2 packs a similar resolution into a smaller panel, it actually achieves a higher pixel density at 353 ppi versus 323 ppi — meaning text and graphics appear slightly sharper per inch. For users who prioritize readability at a glance, the larger canvas of the Balance 2 may win out; for those who value crispness, the Active 2 holds an edge.

A meaningful practical differentiator is water protection. The Active 2 is rated water resistant at 5 ATM, sufficient for swimming in shallow water, while the Balance 2 steps up to waterproof at 10 ATM — suitable for more demanding aquatic activities and greater depth exposure. Overall, the Balance 2 holds a clear design advantage for users who want a larger screen and stronger water protection, while the Active 2 is the stronger choice for those prioritizing a lighter, slimmer, and more everyday-friendly form factor.

Both the Amazfit Active 2 and the Amazfit Balance 2 are equipped with an impressive array of sensors. Both watches monitor blood oxygenation levels, include a heart rate monitor, and feature GPS. They also both have accelerometers, temperature sensors, compasses, barometers, and gyroscopes. Additionally, both devices have a cadence sensor. However, the Active 2 does not monitor perspiration, and neither does the Balance 2.

In terms of sensor features, the two watches are virtually identical. The only notable difference is that the Active 2 has a cadence sensor, which the Balance 2 also has, making both products quite similar in terms of the available sensors.

Overall, both products are well-equipped for tracking a wide variety of metrics with the same sensors. Neither device offers any sensors that the other lacks within this group.

Both the Amazfit Active 2 and the Amazfit Balance 2 are equipped with a wide range of activity tracking features. They both track sleep, distance, steps taken, pace, elevation, and calorie intake, and provide sleep reports. Additionally, both devices can automatically detect activities and offer multi-sport modes, exercise tagging, and stroke counters for swimming.

One notable difference between the two is that the Balance 2 is designed for diving, while the Active 2 is not. Both watches have a route tracker, but the Active 2 also includes a feature designed for golf, which the Balance 2 lacks.

Overall, the activity tracking capabilities of both watches are very similar, with the main differences being that the Balance 2 supports diving and the Active 2 has golf tracking.

The Amazfit Active 2 and the Amazfit Balance 2 offer identical connectivity features. Neither product has a cellular module, but both are compatible with iOS and Android devices. They both support Bluetooth version 5.2, Wi-Fi, and NFC. Additionally, neither device supports ANT+ connectivity.

In summary, there are no differences in the connectivity features between the two models. Both watches provide the same wireless capabilities.

The Amazfit Active 2 and the Amazfit Balance 2 differ significantly in battery life and power. The Active 2 offers a battery life of 10 days, while the Balance 2 has a longer battery life of 21 days. In terms of battery power, the Active 2 is equipped with a 270 mAh battery, while the Balance 2 features a much larger 658 mAh battery.

In power save mode, the Active 2 lasts for 456 hours, while the Balance 2 lasts 67 hours. With GPS on, the Active 2 provides 21 hours of use, whereas the Balance 2 offers 33 hours of GPS usage. Both devices have rechargeable batteries but do not support wireless charging, solar power, or removable batteries.

While both products share similar battery features, the Balance 2 offers significantly longer battery life in all categories compared to the Active 2, thanks to its larger battery capacity.

The Amazfit Active 2 and the Amazfit Balance 2 share many of the same key features, such as HRV tracking, VO2 max measurement, resting heart rate measurement, fast/slow heart rate notifications, readiness level display, call answering capability, phone locator, call control, notifications, silent alarm, vibrating alerts, a stopwatch, and a built-in camera remote control function. Both watches also lack irregular heart rate warnings and ECG technology, and neither includes a front camera.

However, the Balance 2 has an advantage in one area: it acquires GPS faster than the Active 2. In terms of microphone setup, both models feature one microphone, and neither has fall detection.

In summary, the two products offer nearly identical feature sets, with the main difference being the Balance 2's quicker GPS acquisition.

The Amazfit Active 2 and the Amazfit Balance 2 offer identical app and software features. Both watches provide activity reports, inactivity alerts, calorie counting, goal setting, achievements, and a free app. They also support exercise diaries, ad-free usage, coaching, temperature tracking, period notifications, route support, calendar syncing, music playback, fertile window notifications, food diaries, maps, ovulation predictions, start date predictions, video tutorials, widgets, personalization, water intake tracking, weight tracking, live tracking, and BMI tracking.

Both models also lack a barcode scanner in their apps, making them the same in terms of app functionality and available features. There are no differences between the two in this category.

Overall, the app and software capabilities of the Active 2 and Balance 2 are fully matched, with no distinguishing features between the two products in this group.

The Amazfit Active 2 and the Amazfit Balance 2 share the same miscellaneous features. Both watches have a battery level indicator, auto pause, and passcode protection. They are compatible with smart scales and external heart rate monitors. Neither watch is compatible with Windows, Mac OS X, or has an external memory slot. Additionally, both models lack a socket for a 3.5 mm audio jack.

With identical specifications in this category, there are no distinguishing features between the two products in terms of miscellaneous capabilities.

In conclusion, both the Active 2 and the Balance 2 offer the same set of miscellaneous features, with no differences between the two models in this group.
