First of all it depends from phone to phone, what things you have installed, when the last time you restarted... I didn't get such graphs before the patch, and it depends from day to day. As you can see in the second pic, I got 4-5% drop in 10 hours of idle. Also, the third pic shows a 20-22% drop from 11am to 9pm with normal use during the day, around 2% per hour with use, which is very good in my opinion.
