Nice but coole be much better. Charts are very difficult to read and the one on the watch is missing the most important information - the end time and date. There's also this super annoying status info always sticking on the top of all notifications on the watch which cannot be removed or opted out which is bothering me a lot.

This is such an excellent app that I'm giving it five stars even though it won't display properly on my Pixel1 watch. Not a big deal since the version loaded onto my phone (Pixel 6A) is the intended main interface. That displays a ton watch battery info in manipulable graphic manner that allows any reasonably bright non-geek to SEE what's impacting the battery.

I have been using 3C Toolbox since the beginning (10-15 years?) and I just thought about porting the full app to my watch to monitor the battery, but then I found this exists! It works perfect!
