By Leanne Hays
Apple landed in hot water with customers this year when a feature designed to slow the processors of older iPhone models to keep them from suddenly shutting down came to light. Critics maintained that Apple was throttling the speed of earlier iPhone models to push customers towards newer devices, while Apple insisted that the feature was necessary to cope with aging batteries. Now, with iOS 11.3, Apple is letting iPhone users decide for themselves how to manage their iPhone's battery health and processor speed. The first step in this process is making battery health visible, so customers can decide if and when they'd like to replace their battery. Let's get started learning how to check your iPhone's battery health in iOS 11.3, it's quick, easy, and a valuable piece of information about your device. Note that this feature is only available for iPhone 7, 6S, and 6 models.
