Amazfit Active 2 VS Redmi Watch 5

The most striking design difference between the Amazfit Active 2 and the Redmi Watch 5 is screen real estate. The Redmi Watch 5 sports a substantially larger 2.07″ rectangular display compared to the Active 2's 1.32″ circular panel — a difference that translates directly to more readable text, larger maps, and easier interaction with notifications on the wrist. Both use OLED/AMOLED technology and support Always-On Display, so neither has an edge on display quality fundamentals. However, the Active 2 counters with a higher pixel density of 353 ppi versus 324 ppi, meaning its smaller screen is actually sharper per inch — though at these sizes, both are more than adequate for everyday readability.

Where the Active 2 earns a meaningful structural advantage is with its sapphire glass display — a feature the Redmi Watch 5 lacks entirely. Sapphire is significantly harder than standard glass, offering far better resistance to everyday scratches from keys, countertops, and similar hazards. The Active 2 is also noticeably more compact: at 9.9 mm thick and 29.5 g, it undercuts the Redmi Watch 5's 11.3 mm thickness and 33.5 g weight. Over a full day of wear, that difference in bulk and mass is genuinely perceptible, particularly for smaller wrists or during sleep tracking.

Both watches share a 5 ATM water resistance rating and offer replaceable bands, so neither holds an edge on wearability fundamentals. The verdict here depends on use case: the Redmi Watch 5 wins on screen size and is better suited for users who prioritize display visibility, while the Amazfit Active 2 holds a clear advantage in build durability (sapphire glass), slimness, and overall wearability comfort.

The Amazfit Active 2 and the Redmi Watch 5 both include several advanced sensors for fitness tracking. Both watches monitor blood oxygenation levels, feature heart rate monitors, and come with GPS and accelerometers. However, the Active 2 includes additional sensors such as a temperature sensor, compass, barometer, gyroscope, and cadence sensor, which are not available on the Watch 5. The Watch 5 lacks a temperature sensor and barometer, and does not have the cadence sensor found on the Active 2.

Additionally, neither watch monitors perspiration, as both are missing this sensor. While both devices include a gyroscope, which helps with motion tracking, the Active 2 offers a wider array of sensors for more detailed fitness and environmental monitoring compared to the Watch 5.

In summary, the Amazfit Active 2 offers a more comprehensive set of sensors, including features like a barometer and cadence sensor, which the Redmi Watch 5 does not have. Both watches share basic fitness tracking capabilities such as heart rate monitoring, GPS, and accelerometry.

Both the Amazfit Active 2 and the Redmi Watch 5 offer comprehensive activity tracking features, including tracking sleep, distance, steps taken, pace, and elevation. Both devices provide sleep reports and can detect activities automatically. Additionally, both watches include a route tracker, multi-sport mode, exercise tagging, and a stroke counter for swimming. They also track calorie intake, making them well-suited for fitness enthusiasts.

The key difference between the two products in this category is related to golf tracking. The Amazfit Active 2 is designed for golf, whereas the Redmi Watch 5 does not have a golf mode.

Both watches are not designed for diving, so users looking for diving-specific features will need to consider other options. Overall, the two devices have nearly identical activity tracking capabilities, with the only notable difference being the inclusion of a golf mode on the Amazfit Active 2.

Both the Amazfit Active 2 and the Redmi Watch 5 are compatible with iOS and Android devices, offering broad compatibility for most users. Neither device includes a cellular module, so they both rely on Bluetooth for wireless connectivity. The Active 2 supports Bluetooth version 5.2, while the Watch 5 has the slightly newer Bluetooth 5.3. In terms of additional connectivity features, the Active 2 supports Wi-Fi and has NFC, while the Watch 5 lacks Wi-Fi and NFC support.

Another key difference lies in the satellite navigation systems. The Active 2 does not support Galileo, while the Watch 5 does. This means the Watch 5 may have slightly enhanced location tracking capabilities in areas with Galileo coverage, but otherwise, both watches offer GPS functionality.

Overall, while both watches offer the essential connectivity features such as Bluetooth, iOS and Android compatibility, the Active 2 has a slight edge with its support for Wi-Fi, NFC, and the older Bluetooth version 5.2, while the Watch 5 offers Galileo support instead.

The Amazfit Active 2 and the Redmi Watch 5 both feature rechargeable batteries, with the Active 2 having a 270 mAh battery and the Watch 5 equipped with a significantly larger 550 mAh battery. This difference results in the Watch 5 offering a much longer battery life of 24 days, compared to the Active 2's 10 days of battery life.

Neither device supports wireless charging, and both do not feature solar power batteries. Additionally, both watches have non-removable batteries, meaning users cannot replace them easily.

In summary, the Redmi Watch 5 stands out with its longer battery life and larger battery capacity, while both watches share similar charging features and battery design.

The Amazfit Active 2 and the Redmi Watch 5 both come equipped with a range of features aimed at enhancing the user experience. Both watches offer HRV tracking, resting heart rate measurement, call answering, phone locating, call control, notifications, silent alarms, vibrating alerts, a stopwatch, and built-in camera remote control functions. They also both lack ECG technology and irregular heart rate warnings, and neither has fall detection.

The main difference between the two products in this category is the number of microphones. The Active 2 has 1 microphone, while the Watch 5 includes 2 microphones. This could potentially enhance audio quality for features like answering calls or voice commands on the Watch 5.

In summary, both watches share most of the same core features, but the Redmi Watch 5 stands out with an additional microphone, which could provide an advantage in audio-related functions.

Both the Amazfit Active 2 and the Redmi Watch 5 offer similar app and software features, including activity reports, inactivity alerts, calorie counting, goal setting, achievements, and a free app. They both include an exercise diary, coaching, support for routes, syncing with existing calendars, music playback, food diary, ovulation predictions, and weight tracking. Both devices also support widgets, can be personalized, and track water intake.

However, the Amazfit Active 2 offers temperature tracking, which the Redmi Watch 5 does not. Additionally, the Active 2 syncs with existing calendars, while the Watch 5 does not provide this feature. The number of exercises supported also differs slightly, with the Active 2 supporting 160 exercises and the Watch 5 supporting 150.

In terms of period-related features, both watches display fertile window notifications and predict ovulation and start dates. Both devices do not have a barcode scanner in the app. Overall, the Active 2 offers more features in terms of temperature tracking, calendar syncing, and exercise variety, while both watches are otherwise very similar in terms of app functionality.

Both the Amazfit Active 2 and the Redmi Watch 5 include a battery level indicator and are compatible with external heart rate monitors. However, the Active 2 offers a passcode feature, which the Watch 5 does not have. Neither device is compatible with Windows or Mac OS X, and neither includes an external memory slot or a socket for a 3.5 mm audio jack.

In summary, the only key difference in this category is that the Active 2 supports passcode protection, while the Watch 5 does not. Otherwise, both devices share similar compatibility and features.
