Definitely not as good ~ but I strongly believe this is down to whatever apps we have installed and whether these apps have been utilised enough for 10.3. As an example I'm finding a few apps are running a lot more in the background.
I had a problem with my 5s regarding that: It always skipped - on iOS 7 - the same percentages: 60% (went from 61% to 59%) and 30%. My iPhone 6s on iOS 9 does not skip any percentage. Neither does my iPad Pro on iOS 9 as well.
Screen at about 25~35%. Location Settings are all "While using the App" or "Never" if its not available. Wifi on & Bluetooth was always on because of AirPods.
