How is battery health on an iPhone monitored?

The correct approach to monitoring battery health on an iPhone involves accessing the Battery settings within the Settings app. This feature provides detailed information about the battery's maximum capacity compared to when it was new, as well as insights into the battery's performance and usage patterns.

The Battery settings contain a dedicated section called "Battery Health," which shows the current maximum capacity percentage and whether the battery is supporting normal peak performance. This systematic and integrated approach is designed by Apple to give users a reliable understanding of their device's battery condition, making it the most accurate and user-friendly method available directly from the device itself.

Other methods like using third-party apps or checking status bar indicators may not provide the same level of detailed and reliable information as the built-in settings do. Charging times may vary for numerous reasons, and while they can provide some context about battery wear, they lack the precision and detail that the Battery settings provide.
