The Redmi Watch 5 Active features a heart rate sensor that provides generally accurate readings, making it suitable for fitness enthusiasts. Here's a detailed overview of its accuracy:
1. General Accuracy: The heart rate monitoring on the Redmi Watch 5 Active is considered reliable, with some tests showing it to be very close to other devices like the Apple Watch SE, often with only a 1 or 2 beats per minute (BPM) difference[7]. This suggests that for general use, such as resting heart rate or casual monitoring, it performs well.
2. Comparison with Other Devices: In comparisons with other smartwatches, like the Galaxy Fit 3 and Xiaomi Smart Band 9, the Redmi Watch 5 Active's heart rate monitoring was found to be consistent and accurate, though not always the most precise in every scenario[1]. For instance, during a comparison with a fingertip pulse oximeter, the Redmi Watch 5 Active showed minor differences but provided faster results[10].
3. Activity-Specific Accuracy: While the watch is generally accurate, its performance can vary during different activities. For example, during strength training, it has been noted to be quite accurate, often closely matching readings from more precise devices like chest straps[3]. However, during activities with significant wrist movement, such as cycling, wrist-based heart rate monitors like the Redmi Watch 5 Active may experience reduced accuracy due to limitations in photoplethysmography (PPG) technology[3].
4. Limitations: Like many wrist-based heart rate monitors, the Redmi Watch 5 Active may not be as accurate as chest straps during high-intensity or dynamic activities. This is due to the inherent limitations of PPG technology, which can be affected by wrist movement and other factors[3].
Overall, the Redmi Watch 5 Active offers reliable heart rate monitoring for general use and most fitness activities, though it may not be the best choice for high-intensity workouts requiring precise heart rate tracking.
