It’s true! Muninn is here to help report battery life using an ultra-low battery impact approach. So far I’ve had excellent bug reports and feedback, but more is better! Please try it out and post any good/bad observations here.
Source code is also readily available: pebble-dev/watchapps/muninn at master · C-D-Lewis/pebble-dev · GitHub

I guess you’ll make it work with the 1% increment Emery can provide?

It will use whatever the platform provides - indeed for PT2 and P2D this is 1% increments

Like me you can’t test this in current emu, so I guess you tested on hardware? I hope they will add it soon to the emu.
