I've used 40% in the last 15 hours, with 3 1/3 hours screen-on time. That's lighter usage than some days, but in line with expectations for that amount of active use. I'm on the May update, but haven't noticed any difference as a result of updates.
Of course battery consumption depends on many factors, even as simple as whether you are using it indoors or out (on a sunny day the display will use a lot more power outdoors due to the higher brightness).
