The Xiaomi Mi 11 is the first smartphone to be launched with Qualcomm’s new Snapdragon 888 processor. On top of that, it also appears to be the first phone to feature an in-display fingerprint sensor that doubles as a heart rate sensor.
Chinese tech blogger and teardown specialists IO Technology (艾奥 科技) have gotten their hands on a Mi 11 and showcased the on-screen heart rate sensor in action in their teardown video. Unsurprisingly, the location is the same as a typical in-display fingerprint sensor.
From the looks of it, you’ll need to hold your finger in the same spot for 15 seconds to get a measurement through a health app. This is quite long as most heart rate sensors, including Samsung’s older rear-mounted unit, would take 10 seconds or less. You can see how it’s done in the teardown video of the Mi 11 starting at the 8:41 mark.
After the launch of the Mi 11, it was revealed that Goodix is the provider of the ultra-thin in-display optical fingerprint sensor with heart rate monitoring. The company claims that the on-screen heart rate sensor is as accurate as a smart bracelet and watch. According to its website, Goodix also supplies in-display fingerprint sensors to various brands, including OnePlus, Samsung, Vivo, Oppo, Huawei, and Realme.
It is quite rare to see new smartphones with integrated heart rate sensors these days. Samsung used to offer it as standard since the Galaxy S5 in 2014, but the Korean smartphone maker has removed the feature starting with the Galaxy Note 10.
Getting a single reading from a smartphone may not provide a clear picture of your well-being and it is best to have a continuous reading via a fitness tracker or smartwatch. If you just need something to track your heart rate, there are plenty of affordable activity trackers with built-in heart rate monitoring below RM200. This includes Xiaomi Mi Smart Band 5 and Samsung Galaxy Fit 2.
Going back to the teardown of the Mi 11, the video provides a clear look at its internals as they tear down the purple Vegan Leather Lilac version of the device. The rear is clearly plastic which seems quite flexible. By removing the camera module, the video reveals the Sony 108MP ISOCELL HMX sensor with OIS, a 13MP Omnivision CMOS OV13B10 for its wide-angle shooter, and a 5MP Samsung S5K5E9 sensor for its macro camera.
The Mi 11 also features a vapor chamber to keep its Snapdragon 888 processor cool and receives a respectable 4,600 mAh lithium-ion battery from Sunwoda Electronic. You can watch the full teardown video below:
