Sorry to say - it will never get better. You may be able to squeeze a few extra hours out of it, maybe even get 24 hrs at some stage, but sadly they are just terrible for battery life. I had one, and it takes a few months for the watch to figure out it’s usage patterns and build up the time saving. The only ONLY way to make it last longer is to cut back on all the fun stuff, the auto screen turn on when you twist your wrist, the vibration for notifications (any notifications) and keep your clock screen as basic and boring as possible.
ohh and for the love of god don’t get your 50M water proof watch wet as it hates the water.
Mine after almost 2 years to the day decided when I wore it in the shower to freshen she strap that it was not going to be water proof today and screen died.
So I will never be getting another Samsung watch again, great concept but terrible battery and not waterproof at all after the guarantee expires - to the week.
