Today I opened and set up my new 10.5, which I love. The only thing is that after a couple of hours I decided to run the Battery Life app and it indicated that the battery has 3% wear on it. Throughout the day the app has been reporting that the device has only 97-99% of its original battery capacity left (i.e., that there has been 1-3% battery wear on the first day of using it). Is this normal for a brand new out of the box device? Some seem to suggest the app is inaccurate and others that it is pretty accurate. Any thoughts on this? Has anyone else run this app ( https://itunes.apple.com/app/id1080930585 )on their new Pro and what are the results? Thanks for any advice or tips, really appreciate it.
