ChargeCurve: Battery History

ChargeCurve turns your phone's battery readings into a history of charge sessions, so you can see how each charge actually went.

• Check battery level, charging status, temperature and current at a glance
• Each session shows when it started, how long it ran and the power source used
• Compare starting and ending battery levels for every charge
• Follow battery temperature and charge rate on simple trend charts
• Add your own notes about charging conditions
• Export your charge history as a CSV file

Sessions begin once ChargeCurve first sees your phone plugged in, and readings depend on what your device reports. Background readings are best-effort, so charts can show gaps. It does not diagnose battery health.
