As an iPhone user, you may have noticed that your device comes with a battery health indicator that displays the percentage of maximum battery capacity available. This feature was introduced in iOS 11.3 to allow users to monitor their battery health and prevent unexpected shutdowns. However, the question remains, how accurate is the battery health indicator on iPhones?

How Accurate is the Battery Health Indicator on iPhones?
