As an update to my post a couple of weeks ago I got a new unit from the Apple store as a replacement because my compass sensor was broken. Apple refused to take it back or officially acknowledge the battery had an issue but because the compass was broken I was able to walk out of the store with a replacement unit in hand. The replacement is working great, couldn’t be happier. I am 100% convinced that a some sort of hardware issue was at fault. Maybe the broken compass sensor was drawing power when it was not supposed to or something. If you are having this issue I would recommend to push for a replacement, best of luck!
