OPPO announced the OPPO Find X5 Pro globally ahead of MWC 2022. It is the latest flagship smartphone from the company and the successor of last year’s OPPO Find X3 Pro. Almost a month after its debut, the company introduces an interesting feature.

The OPPO Find X5 Pro can be now used to measure heart rate in China. The phone does not use an optical fingerprint-heart rate combo sensor like the Xiaomi Mi 11 and the realme GT2 Pro. 

Instead, it relies on an IMU (Inertial Measurement Unit) sensor, which is capable of measuring triaxial acceleration and triaxial angular velocity. OPPO is the world’s first smartphone manufacturer to measure heart rate using an IMU sensor, which consists of an accelerometer and a gyroscope.

In order to measure heart rate using their OPPO Find X5 Pro, users need to open the OPPO Health app (v3.13 or above), navigate to Heart Rate > Phone Heart Rate Measurement, and place the handset on their chest. Alternately, users can ask OPPO Xiaobu (Breeno) virtual assistant “measure heart rate” to access the feature quickly.

The heart rate data will be displayed on the screen within 12-15 seconds. The result will be based on the vibration reading through the IMU sensor and OPPO Health algorithm processing.

We are not sure how accurate the readings are. Either way, it is not recommended to rely on this feature for medical use. The same can be said for every fitness-focused wearable available in the market. Only consider them as a tool to help you achieve a healthier lifestyle.
