Oh sorry - I pretty arbitrarily chose to build for android 11 because that was what the tutorial I was reading built on. I'll try to downgrade it and see if it's still happy - something for version 0.03 when I get some time
I made a Solis app too. It's probably not as extensive as above but it's free and gives you notifications on high and low battery, which is what I really want:

Feedback welcome.
Using the Solis API, I made a little app & widget that displays notifications when the battery is high/low:

It won't help get your numbers more accurate, but it makes it less painful (for me at least) to see what's...
