ChargeLog, an instrument for battery charging
ChargeLog records Android and Wear OS charging sessions, including power curves, charging phases, temperature, and physical context.
Field notes
ChargeLog treats charging as a measurement session rather than a battery-optimization problem. It records battery-side watts, temperature, device position, screen state, and connection type, then divides the curve into five named phases. Sessions are kept in a local phone database, while the Wear OS version records on the watch and synchronizes over Bluetooth after an explicit first-time consent step. The project is marked PRE-ALPHA, and its site says it is headed to Google Play.
