I have had it for 10 days and I still haven't charged it, I will share my opinion as a first-time user of a smartwatch. I got it clearly only for exercises, walking, running, nutrition, and measuring calories in general for weight loss, etc.
From 85 kg I have gone down to 75, I'm not kidding, thanks to this watch, your measurements are accurate in everything! Heart rate, walking, running, how many calories you have burned, what kind of exercise you want to do, and it talks to you, gives you instructions, along with the Huawei app that records what you consume and other various programs, everything is perfect and it applies to you according to age, gender, and height.
The battery is super, as I said above, it's been 10 days since I charged it and it's at 50%, the screen is very bright even in the sun with good clarity, wonderful premium device construction especially the black one, good speaker, when you wear it, it doesn't bother you at all, on the contrary, it's very convenient and looks very stylish when you wear it and it's not heavy to hurt your arm.
The only negative thing I have to say is that I don't trust putting it in water! I don't want to risk it with the comments I've seen and I don't want to experience the same.
Overall, I am very VERY satisfied with this particular watch, I was between this and the Galaxy Watch 6 but I don't need a watch that has Wi-Fi and downloads apps and generally works like a phone, I got it for simple things.
If you are thinking of getting it, DON'T hesitate at all! It's worth every euro I spent and more!
