I have the exact same issue. My bangle.js 2 accumulates around 40 to 45 seconds per day, so it seems that it would be like 5 minutes per week.
Right now I have stable 2.22. I used to have the watch unconnected for several days and it didn't happen before. Recently I have connected nearly every day, so I don't know which update broke it. My guess is that it happens since some development update during 2.21.x.
