Anyone know of a way? It probably needs some sort of app on the phone to report the battery state…I had an idea for charging the phone to the 100% at the last possible time before I get up in the morning - on the theory that lithium batteries prefer to be between 20 and 80% for the most time.

Check out this tutorial. I have a modified version pulling in battery level and charging state. Also does location.
