Have had my sense for a year. Two days ago, it randomly started turning off and on, stuck in a loop and drained the battery in a few minutes. I charged it, then did a factory reset, deleted the device and re added it on the app. It is no longer stuck in a loop, but from a full charge, drains completely in just a couple hours. I have the same settings I have always had on. Sp02 etc. But disabled them to see if there was a difference and it still went from full to 0% in just a couple hours.
