I deactivate always on display, raise the wrist to turn it on, and automatic workout detection. If I keep all these features on I get about a week of battery life, the blood oxygen feature in it is on demand, it doesn't run all the time, it runs a test only when you ask for one, this may give it some advantage compared to your watch, but the rest is the same, the heart rate sensor runs all the time, it's connected to my phone, and displays all the notifications that I get in it, and at night it tracks my sleep, the problem with the other watches is that even when you deactivate a lot of features, you don't get a significant boost in battery life, why? is it because the OS is bigger and more complex?
From my experience I think the algorithm gotten a little bit worse, the only drawback of removing dislikes that I am experiencing is that it's getting more difficult for me to realize if a video is just a spam or click-bit, now I need to spend a couple of seconds watching the video, before I used to glance at the dislike numbers, if rating is deactivated or the dislikes are far more than the likes I close the video.
