Have experienced the increased battery drain since software update, draining at 5% per hour. Coincidently bought a new phone at the weekend and transferred the watch over to that, but didn’t install Samsung health on the phone or use it on the watch. The process made the watch reset and I restored settings, but it kept the updated software. I have the watch in normal mode, receiving all my normal notifications and tracking the odd short walk - I am now at 60 hours since the last charge and have 38% battery left. It’s dropping at roughly 1% per hour, which I am very happy with; at this rate I might get 4 days on normal mode!!. Hope this helps some of you - something else to try.
