After the latest update, my fitness tracker has a habit of notifying me that it needs to be charged at 4AM in the morning. I don’t have time to charge it in the morning before work. So, I’m stuck waiting to charge it until that evening and hoping that the battery doesn’t die during a workout. To me, the old behavior where I received a notification when the battery discharged to a certain level even if it is was during the work day was better.
