Diagnosing battery usage

The battery draw of my bangle.js is weird. It would use 89% everyday for a couple days, then suddenly lose all charges in one night. Often I went to sleep with 5070% battery and wake up with a dead watch.

Is there a way to log battery percentage overtime? And is it possible to figure out what is drawing the most power at any given time?

Yes, there is! There's an app called Power Manager that can help you find out what uses the power: https://banglejs.com/apps/?id=powermanager

And there's a discussion about it being used to try and find causes for power usage here: https://forum.espruino.com/conversations/385629/#comment16946032
