## Review summary

Battery HD+ Pro is valued for detailed battery analytics, a life calculator, useful alerts, and a clean UI, with long-term reliability.

- Calibration feature that helps improve battery understanding.

### Cons

- Calibration reliability is inconsistent across devices/OS versions, with hangs and non-functionality on several devices.
- Data accuracy issues: incorrect battery level readings on iOS 17 and inaccurate charging notifications, including mismatch with Apple Watch data.
- Occasional stability issues or crashes described by users (often tied to calibration).
