I got TESTED in China’s Incredible Biometrics Lab

Linus got the grand tour of Huawei’s Advanced Health Lab—think motion-capture cameras tracking basketball jump shots, rock-climbing grips and even badminton smashes, plus a giant treadmill that mimics city streets and an underwater rig to test swim-tracking. Along the way he pits the latest GT6 Pro and Watch Ultimate 2 through hoops, ping-pong, cycling and more to see how accurate these wearables really are.

This behind-the-scenes sneak peek shows how Huawei fine-tunes every sensor to make your smartwatch fitness data as legit as possible—no filters, just science (and maybe a little friendly competition).
