Despite the general "buns", there are also disadvantages.
1. Autonomous work. Someone says three days? Ha! I have a device with the disabled option to turn on the screen by turning the wrist for a maximum of one and a half days, if I do not use the training functions and do not use it as a player: just notifications and programs for recording sleep. I don't take off my watch at night. Yes, I set the display brightness to a minimum, and turned off the measurement of the pulse in a constant mode. It didn't help much. The same Gear S3, according to reviews, lives a day and a half longer.
2. Sleep control. Before buying a smart watch, I didn’t attach much importance to sleep, but with a smart alarm clock and analysis of sleep phases, I realized how important it is to sleep properly for daily work. So, Apple developers sucked this moment. Yes, there are third-party applications in the market, where for 800 wooden ones they promise all sleep analytics and even more, but in fact you will have to set the start and end time of sleep yourself, and this is complete nonsense! Yesterday I bought the AutoSleep program for 229, where the developers lied about full automation. According to her, I slept for half an hour today, although it was a full seven hours with a tail. Great, thanks for the wasted money.
3. Navigation through the menu really happens quickly, cool and without sticking, but as soon as you decide to go into some program that is not very optimized for the device, get ready to wait two seconds before turning it on. Of course, Apple has the largest volume of applications in the store, but it feels like they were washed down in a hurry for show. The same Samsung has fewer programs, but they turn on faster.
