Since the iOS 11.4 update my watch battery drains in 1 day I generally get 2 days worth of battery life that includes when I use the work out app and sleeping with it. I have checked all y settings and nothing has changed, any insight would be greatly appreciated thank you

It will take 24-48 hours for the new operating system to finish it house keeping, as well as resync things it wants from the iPhone.
Power cycle the Apple Watch and your iPhone (at least once, but maybe once or twice a day until the Apple Watch battery consumption returns to normal.

For some steps that are not in the MacObserver article.
iPhone -> "Watch" app -> General -> Reset -> Reset Sync Data
Again it may take a day or two for the rsync'ing of data to settle down.
As a point of reference, my Apple Watch Series 4 with 90% battery health maximum capacity, was back to normal after 24 hours (watchOS 10.5). I did 1 mid-day recharge, and I power cycled my Apple Watch and iPhone twice.
You should not stretch the time between charging your Series 10, as that will tend to run the battery very low, and Li-Ion batteries do not like deep discharging. It is one of the fastest ways to destroy a Li-Ion battery.
You should charge it every day. The extra capacity is there so that as the battery ages, it will still give you the rated 18 hours a day. But not if you abuse the battery.
It's only rated for 18 hours of use.
Check Walkie Talkie hasn't randomly enabled itself. I had the same issue and then when I checked Walkie Talkie icon was glowing as if I'd activated it despite never having used it (and fairly sure I'd previously deleted the app a few updates ago because I would never use it).
