1) autonomy: here it turns out to be about two weeks (exactly two weeks, I did it WITHOUT starting running workouts, all sensors were always on. Sometimes I answered calls from them, well, I read messages. My average running workout is 70-80 minutes, I ate 5-6% of the charge, i. E. almost like a day of use. Bottom line: gorgeous, as for me, when compared with competitors. The same Huawei watch 3, with his wife - live 2-3 days. Because of what she has periodically bombing.
2) Interface: everything is ok. Intuitive and simple. Not much has changed since my previous Huawei Watch GT. Little things like autostart of the timer for 1-5-15 minutes, etc. please. In my version, it had to be launched with one more click, which did not make much sense.
Slightly annoying choice of application icons in the main menu (they are small and all do not fit). You can swap app icons.
3) Design: concise and stylish. A matter of taste. Huge selection of dials for every taste and color.
4) Waterproof. Feel free to shower or take a bath. With the first version, I swam many times and dived up to 3 meters (did not try again) in the sea. I suspect that it is also possible here, until I checked it.
5) The pulse is measured well (quickly and fairly accurately, I checked it more than once with a stopwatch) until you sweat.
Temperature measurement is buggy, because. Skin temperature and body temperature are two different things.
VO2max, blood oxygen saturation. A good set for an amateur athlete.
6) Headset - approx. It's normal for both me and me. Of course, I will not use it), in most cases, because there is a normal headset for the ears, but sometimes it happens. I do not use the clock to play music, because. I carry my phone with me for jogging, but I checked it - it works well.
7) Vibration alarm and vibration in general: it has become weaker than in the Watch GT of the first version, but I still wake up on them without problems, incl. Let's take it as a plus.
