ChargeLog: A Battery-Side Instrument
An Android and Wear OS app that records each charging session as a local, analyzable record of power, phases, temperature, and physical context.
Field notes
ChargeLog stores every plug-in as a local session, then samples battery-side watts, temperature, charging phase, and conditions such as wired or wireless use and screen state. Its curve is divided into five named phases, from ramp through trickle, and the site says repeated measurements can answer questions such as the time required to reach 80 percent. Watch sessions are described as recording on the watch and transferring over Bluetooth after an initial permission prompt.
