BattAI: Battery health score

About

BattAI • BattAI uses five values from public iOS APIs: battery level, charge state, Low Power Mode, whole-device thermal state, and time. Other results are calculated from those readings or added by you. Each detail shows its source and limits. • BattAI has no account, telemetry, ads, or network requests. Data stays on this device, except for a minimal feature-limited snapshot sent directly to your paired Apple Watch. Sampling is limited, analysis runs at most every five minutes, estimates use ranges, and missing data stays missing.

BattAI labels every other result as estimated or provided by you. • The fixed rules follow established lithium-ion guidance on deep discharge, long periods at high charge, heat, and charge volume. Apple’s 80% maximum-capacity service benchmark is kept separate from BattAI coaching bands. No result promises extra battery life. Understand your battery over time • One payment. Lifetime access.
