The Huawei Band 4 now has SpO2 thanks to a firmware upgrade

Owners of the Huawei Band 4 will be pleased to learn that the wristband can now monitor blood oxygen levels. The functionality was added as a result of a firmware upgrade.

Last October, the $30 fitness bracelet was released. The device is a good alternative for someone who only wants to track their activity and doesn’t need all the bells and whistles. The device is just a redesigned Honor Band 5i. The biggest difference between both is the Huawei Band’s pill-shaped home button vs the Honor Band’s capacitive one.

The Huawei Band 4 Pro, a sequel, was introduced towards the end of 2019. This one is a little more expensive at $60, but it has a SpO2 sensor, GPS, and NFC.

Huawei Band 4 will soon receive the first of these three upgrades. Software version 1.0.2.96 adds blood oxygen functionality. The file weighs in at 5.46 megabytes.

The levels of oxygen saturation in the blood are monitored using a SpO2 sensor. In terms of percent, typical values are in the upper 90s, with most of them above 96 percent. If you have breathing problems, such as sleep apnea, your levels may drop. This can be concerning, thus the Huawei update is beneficial.

The update is being rolled out in phases, so if you haven’t received it yet, be patient. Make sure there’s at least 20% battery life left before refreshing. It takes roughly 20 minutes to install the update.

Last month, the company did something similar with Watch GT2. The pulse Ox function was also added. This confirms that the essential hardware was previously included in last year’s wearables; it was only a matter of activating it.
