Well my HRM is off. Before I upgraded it was ten minutes, but when I noticed the battery dropping so quickly after the upgrade I turned it off. LCD brightness is 0.1, timeout 5 seconds.
I tried downgrading back to v12 but nothing worked, or at least neither Anton nor the app loader worked, I'd get errors about bad line termination on my watch or something like that, and errors about bad JSON in gadgetbridge.
I was able to go as early as v19. Fully charged last night, it's now been 12 hours and it's only down 3% which is a huge improvement.
I'm going to let this run for a few days then upgrade one version at a time to see if I can pinpoint the version that caused my problem.
I swear, if I get to v24 and it continues running fine I'll be mad. I don't have to tell you about the frustration of unreproducible errors :p
I'll update in a week or so.
