Mi Band 5 with 1.1 inches display is larger than Mi Band 4 0.95 inches. Moreover, the bezel is slimmer and this allows you to see more at a glance which represents a 20% increase in the viewing area. Mi Band 5 also features 100+ custom watch faces which include 54 IP themes such as Spongebob Squarepants, Neon Genesis Evangelion, Hatsune Miku, and Detective Conan. Both smartbands have case materials made of polycarbonate, TPU straps, and 2.5D reinforced glass, while waterproof rating is still 5ATM making any if these ideal to wear to the shower or pool.

Xiaomi added more activity tracking features to Mi Band 5 which makes it a more comprehensive fitness tracker. While both smartbands will track your heart rate continuously, sleep, steps, calories with preloaded sport modes, Mi Band 5 can detect an irregular heartbeat and will alert you, as well as tracks your sleep 24/7 in three stages; deep, light and REM compared to Mi Band 4 that tracks your sleep in two stages; deep and light only at night.

Other features that are new include; a menstrual cycle tracking feature that can help women track period cycles. Mi Band 5 can also help you manage stress via guided breathing session, and blood oxygen tracking is also present to help track how well your blood utilizes oxygen.

Also added is the Personal Activity Intelligence (PAI) vitality index; a new, innovative system that converts your heart rate data into a personalized score that indicates the level of activity required in order to maintain good health.

And while Mi Band 5 features 11 preloaded workout modes, Mi Band 4 features 6.

While both smartbands feature, music playback on phone, find my phone, phone unlocking, do not disturb mode, event reminder, and notification, Xiaomi has added to Mi Band 5 the ability to control phone camera.

Xiaomi also added magnetic charging to Mi Band 5 ditching charging dock used on Mi Band 4. This makes it easier to charge Mi Band 5 by simply placing the charger at the back instead of having to remove the Band from the strap. And while Mi Band 5 despite having more features still has about 2 weeks long battery life with continuous usage.

Should You Upgrade?

Clearly, Mi Band 5 is a better smartband than Mi Band 4. It has a larger display that allows you to see more at a glance and also features more health tracking features that make it a more comprehensive fitness tracker with long battery life.

With the addition of menstrual cycle, stress tracking, blood oxygen monitoring, PAI, more preset sport modes, larger and brighter display, the introduction of magnetic charging, and long battery life, yet very low price makes Mi Band 5 a better smartband than it’s predecessor. It’s a wise bargain, especially when compared to other close competitors like Galaxy Fit, Fitbit Charge 3.

Considering its low price, I think it’s worth upgrading to Mi Band 5, and if you’re yet to own any of these, you should go for Mi Band 5. I already ordered one, and you should expect a video comparison between these two soon.
