## Description

See when your iPhone battery really needs replacing: health score, maximum capacity over time and an estimated time to 80%. PDF report included. Free to start.

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.

Health
• Battery health score
• What shapes the score
• Maximum capacity over time
• Estimated time to 80%

Charging
• Charge care
• Charge range
• Charge rate

Reports
• Create a clear battery report for service, resale, or your own records.
• Full report: the app's charts and text
• The same report saved as a PNG
• All of your data as a plain-text table

Privacy
• No ads, analytics, tracking, third-party SDKs, or internet requests. Data stays here, except for a minimal snapshot sent directly to your paired Apple Watch.
• Public iOS APIs provide battery level, charge state, Low Power Mode, whole-device thermal state, and time. 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. No subscription.
• Your purchase is tied to your Apple Account and works on your devices.
