Beta 2 greatly improved my battery life on iPhone 7. It runs smoothly.
However I have a problem, Apple Health shows ridiculously high number of flights climbed, it shows like 150 flights while it should be 4 or 5. I was with a friend all day (he's on 11.1), we walked a lot, our number of steps taken are almost the same, his number of flights are OK but mine is skyrocketed. Our barometer readings are almost identical. So it is possible that it's a software issue. I cannot find a solution on the internet, should I try a clean installation?
