How would you know about the battery life this quickly? I'm not saying your post had credibility to begin with, but if it did, it's certainly gone now.
I always add this at the bottom of the post -- it takes us a bit to get the info on what's new since we need to install and look through everything. A what's new list is up now.Just requesting MacRumors to put "What's New in Beta 3" at the top and have a list with screenshots if necessary to accompany it and "What's new in 11.3" below it. So frustrating to read it otherwise.
