Amazfit Active vs Redmi Watch 4: hardware

look and feel

Starting with the appearance, Amazfit Active adopts a square shape, made from a combination of aluminum alloy and plastic, with a special mix of stainless steel and plastic for the Lavender Purple variant. This gives it a modern and versatile look, suitable for both casual and formal wear. The Redmi Watch 4, although also square, is differentiated by a plastic back and an aluminum frame with a stainless steel finish, which offers a more robust and durable feel.

The Active features a single button, emphasizing a minimalist design. The Redmi Watch 4, on the other hand, includes a rotating crown as a physical button, adding a classic watch element that provides a tactile and intuitive way to navigate the watch interface.

Screen, color options, water resistance.

Both watches feature AMOLED displays, but the Amazfit Active has a slightly smaller 1.75-inch display compared to the larger 1.97-inch display on the Redmi Watch 4. The Redmi Watch 4 also offers a higher maximum brightness , which improves visibility in various lighting conditions.

Of course, you have some color options. But the Amazfit Active offers more variety. Your options include Midnight Black, Petal Pink, and Lavender Purple. The Redmi Watch 4 sticks to the classic black and white, attractive to users who prefer more basic color combinations.

Both watches have the same water resistance rating of 5 ATM. This makes them suitable for swimming and other water-related activities.

Sensor technology

Moving on to sensor technology, the Amazfit Active is equipped with the BioTracker PPG sensor, expert in accurate heart rate monitoring. The company doesn’t say which version of the sensor, but we suspect it is BioTracker 4.0. This is complemented by an accelerometer for motion tracking, a geomagnetic sensor for orientation and a unique temperature sensor, expanding its reach for health and environmental monitoring. Its GPS connectivity is comprehensive and supports systems such as GPS, Galileo, Glonass, Qzss and Beidou, ensuring reliable location tracking globally. However, it lacks NFC, which could be a limitation for users who prefer contactless payments. A standout feature of the Amazfit Active is its music storage capacity, allowing up to 250MB of space for music, satisfying users who enjoy having their playlists close at hand during workouts or daily routines.

In contrast, the Redmi Watch 4 also features a heart rate monitor, but ups the functionality with a 4-channel PPG sensor for more detailed heart rate data. It includes an accelerometer, compass, gyroscope and SpO2 sensor to monitor blood oxygen level. Like the Amazfit Active, it is compatible with a wide range of GPS systems, including GPS, GLONASS, Galileo, BDS and QZSS. One advantage of the Redmi Watch 4 is its NFC support, making it more attractive to users who rely on contactless transactions, although this feature depends on the region. However, it doesn’t offer music storage, which could be a disadvantage for those who prefer to listen to their music directly on the device.

Battery duration

Both the Amazfit Active and Redmi Watch 4 offer impressive battery life, but with some differences to suit different user needs. The Amazfit Active has a battery life of up to 14 days with normal use, expandable to 30 days in battery saving mode and up to 10 days with intensive use. This makes it a reliable option for those who need a balance between regular and heavy use.

On the other hand, the Redmi Watch 4, powered by a 420 mAh battery, promises about 20 days of battery life with normal use and 7 days with more intensive use, including the always-on display feature. The inclusion of fast charging on the Redmi Watch 4 adds convenience and significantly reduces downtime.
