Being a former android user, it doesn't look like you did too much during that usage. You should have showed how much time besides the percentage of the display. To show how long the display was actually on for. That's just my opinion, not trying to get anything started, just stating a little more screenshots could have been showed. Here's some screenshots of what I was talking about, from when I was on the galaxy s3.
dont know how moto or droid calculates it. . .but i am a reasonably heavy user. had location services on all day, multiple apps on. left my house at 7 am and the phone was cranking at 11 pm. my iphone 4s on the same daily schedule / same usage wouldn't make it past 130pm. i actually played youtube videos the last 15 minutes on 1% to kill it as i am trying to fully discharge the battery since its early days. . .battery is quite possibly double what i have observed on the iphone 4s or 5
