Current start of charge.
Settings I have always adopted the following for all my Samsung watches, some where LTE like my current but I tried and then turned off 4G as it wasn't worth £8 a month when I 99% of the time have my mobile with me.
Setting, brightness 6, wifi off, location on, nfc on, notifications around 12 on, stealth stress and HR on continuous as is SPo2, wahe up gestures all off, except screen on for alerts. Set auto detect for key exercises and also use Galaxy Bud manager.
Watch phase always find the stock are best for battery, only have WIDGETS active for Composition, BP, and Galaxy Buds.
I wear my watch 24/7
