Welcome to Android Central! That's not unusual battery usage. It looks like you were playing Magic for most of the time, and the screen was on almost the whole time. So it looks like you had around 5 hours of total screen-on time, with battery to spare, and you weren't even starting at 100%. On my 2013 N7, I usually get 5-6 hours of total screen-on time per charge, which is normal. The 8-9 hour screen time you see advertised refers to video tests where they have the device running a video and doing nothing else, which eases the strain on the CPU and battery. But in the real world, people open and close apps, switch between apps, and do various things that use a varying amount of CPU and battery, so those video tests always overestimate.
