The battery life remains over 8 days, and up to 10 days for the Pro version, which is standard for Huawei watches and one of my personal favorite aspects. The wireless charging is also improved, and now you can charge up from 10% to 100% in an hour. The watch continuously monitors health metrics 24/7, including sleep, heart rate, oxygen saturation, and occasionally measures ECG and arterial stiffness. During testing, I tried the sports tracking features, especially for swimming and diving, and the watch measured the parameters quite accurately. Although it didn’t track the pool length perfectly (I was swimming in a smaller 25-meter water polo pool), I was most impressed by the diving tracking, which works by measuring the pressure on the speaker membrane. I tested it at a depth of 6 meters.
