A simple Lua app for Playdate that displays the current battery charging state, voltage, and estimated % remaining (state of charge) using Panic-provided APIs. It also includes some general information about lithium-ion batteries, and information on why the Playdate's battery indicator isn't as accurate as, say, a smartphone's.
