Xiaomi Mi Band 4 vs Mi Band 5 – The Complete Comparison

Design & Display

In terms of design, there’s barely a noticeable difference between the two models. Both are compact and sleek, but the Mi Band 5 features a slightly larger 1.1-inch AMOLED display compared to the 0.95-inch AMOLED screen of the Mi Band 4. The resolution has also improved slightly: 126 × 294 for the Mi Band 5 vs 120 × 240 for the Mi Band 4. Due to its slightly larger build, the Mi Band 5 weighs 23.3g, just 1.1g more than the 22g Mi Band 4.

Battery Life

Battery life is often a deciding factor. The Mi Band 5 has a slightly smaller battery capacity (100mAh) compared to the Mi Band 4 (135mAh), which means it lasts a bit less on a single charge. Still, it offers up to 14 days of use, which is 6 days shorter than the Mi Band 4’s impressive 20-day battery life. On the upside, charging is now much more convenient, instead of removing the tracker from the band, the Mi Band 5 uses magnetic charging for quick and easy power-ups.

Water Resistance

Both models are rated 5ATM water-resistant (up to 50 meters), making them suitable for swimming at the surface or showering, as long as there are no sudden temperature changes. They are not designed for deep diving or high-pressure water activities. Xiaomi also includes multiple swim modes like freestyle, backstroke, and butterfly stroke for accurate tracking.

Tracking Features – Activity, Health & Sleep

Sleep Tracking

The Mi Band 5 offers improved sleep tracking accuracy compared to its predecessor. While the Mi Band 4 tracked Awake, Light Sleep, and Deep Sleep, the Mi Band 5 adds REM (Rapid Eye Movement) monitoring for deeper insights. The companion app also provides personalized suggestions to improve sleep quality.

Activity Tracking

The Mi Band 5 supports more workout types than the Mi Band 4:

• Shared between both: Walking, Outdoor Running, Treadmill, Cycling, Pool Swimming, Freestyle
• Exclusive to Mi Band 5: Indoor Cycling, Rowing Machine, Yoga, Elliptical, Rope Jump

This nearly doubles the number of activities you can track, making it far more versatile for fitness enthusiasts.

Stress Monitoring

The Mi Band 5 introduces a stress tracking feature, measuring your stress levels using heart rate readings and internal algorithms. While Xiaomi does not detail its exact accuracy, it provides useful feedback so you can take breaks when needed.

Breathing Exercises

Another new addition is the Breathing Mode, which guides you through calming breathing sessions with on-screen animations and gentle vibrations to help you relax and refocus.
