First of all, macOS 27 is known as macOS Golden Gate, not Ventura.
Secondly, the current macOS Golden Gate version is 27.0.1.
Finally, regarding the battery, see especially the second paragraph under “Performance and battery impact“ here:
About Apple software updates - Apple Support
A temporary impact on battery life immediately after a software update is to be expected.
