My battery health is 92% it of course dropped after upgrading to os10. As this summer I’ve had this watch replaced by Apple for like for like. It’s just bug in the system with some watch faces which using so much battery getting information like weather conditions

Thanks for advice, purchasing watch with os 9 is generally really hard as most of the users update them to newer version :( I guess I will just wait and use series 7 will it dies it has many scratches but still working fine just battery is funny. Some days it will be holding charge all day, some of days with sleep tracking and charging before bed at 12 o clock I have 30% left and generally not using watch at all just wearing at the wrist and driving
