I will try to write here everything that I would be interested in before buying and is often not mentioned in all kinds of reviews.: I use the watch with the following features: Connection to the phone via BT - nonstop, WiFi - off, brightness automatic, screen off - after 5 seconds, Allways on displays - off, notifications - mirroring the phone, arrival of notifications - lights up the display, sleep tracking - extended with breathing rate, heart rate measurement - all day, stress level measurement - all day, SPO2 measurement - all day, gesture Light up when tilting - on, other gestures off. That's how they suit me best so far. With this setup, I'm getting 3 days of battery life in smart mode (1. I charge the day in the evening and have to charge on the 4th day in the evening). I was at 70+% in economy mode after 4 days. The main differences between smart mode and power saving mode are that in power saving mode there is no possibility to use additionally installed applications (e.g. when I play music on my phone, I can't control it on my watch). Another little thing is that not all emoticons are displayed in notifications. Otherwise, they work the same in power saving mode, i.e. notifications are coming, the measurement works both at night and during the day and during exercise. Pairing with the phone is fine, the values in the mobile app sync quickly, I haven't found any problem in this. Worse is the watch settings, where something can only be set in the watch and something only in the phone. However, once I had it set up the way I was most comfortable with, I didn't touch the settings anymore. I was worried about the automatic brightness according to the reviews, but it works perfectly for me. Brightness high in sunlight, brightness low in darkness. Only with the long sleeve covering the left part of the watch there is a problem - the sensors are probably in the left part of the dial, so when the sleeve covers my watch even 1/4, the watch senses it as if I am in the dark. After the first boot, 2 system updates immediately, which together took over 4 hours. You need to charge your watch during the update. At the beginning I found the system a bit stuck, the animations were slightly stuttering, but after 2 days it seemed to settle down and since then everything has been smooth. Notifications can either be mirrored from your phone or you can choose only from specific apps. When doing exercises using GPS (when you want to map a route) you have to wait a while for the GNS signal (when you want to record the route from the beginning, it takes a few seconds) otherwise you can start without it and after a few seconds it will catch on. As for the sync between the watch and phone, the alarm set on the phone is not reflected in the watch app, but it works - the watch picks up and sounds and the alarm can be turned off via the watch! The Do Not Disturb setting on the phone is again not translated to the watch - it has to be set in the watch as well (a small thing, one swipe up and one click). When I receive a call on my watch, the sound comes from the watch, but as soon as I make a call on my phone, e.g. I turn off the microphone, the call is redirected to the phone and I haven't found a way to put it back on the watch (this was just an experiment, I don't use it at all). When listening to music, a music note symbol appears on the watch face, and when you click on it, the music controls are displayed - song name, time, option to skip or rewind the song, volume control with the crown. The navigation set on the phone projected onto the watch only works via Google maps so far. The only thing I'm a bit sorry about is the unsupported ECG and picture display, where so far only in Whatsapp and in messages you can see a preview of the picture - you can't click and zoom. In other apps (gmail - not even preview, not even with install on watch, messenger - not possible of course, when it is not supported on watch systems). Replying to messages is not only possible on messenger. The only "BUG" I've encountered that pisses me off is that when I have an event with a long name (multiple words) in my calendar, the notification of the upcoming event gets stuck on the main screen - admittedly it's just a thin strip with the name of the event and doesn't even prevent the time from showing, but it just gets in the way and a restart is required. All in all, they meet everything I expected from them. 5/5.
