The algorithm aims to ensure that your iPhone is still fully charged when unplugged. Marc Larochelle with his perspective on FileMaker Cloud: a followup session at DevCon 2016. Your iPhone uses on-device machine learning to learn your daily charging routine so that Optimized Battery Charging activates only when your iPhone predicts it will be connected to a charger for an extended period of time. When the feature is enabled, your iPhone will delay charging past 80% in certain situations. With iOS 13 and later, Optimized Battery Charging is designed to reduce the wear on your battery and improve its lifespan by reducing the time your iPhone spends fully charged.

Learn more about iPhone battery and performance and how to maximize battery performance and lifespan. As lithium-ion batteries chemically age, the amount of charge they can hold diminishes, resulting in reduced battery life and reduced peak performance. All rechargeable batteries are consumable components that become less effective as they chemically age. A battery's chemical age results from a complex combination of several factors, including temperature history and charging pattern. For information about new and changed features in FileMaker Pro, see Help. A battery’s lifespan is related to its chemical age, which is more than just the length of time since the battery was assembled. Welcome to Claris FileMaker Pro, which helps you quickly create custom apps that work seamlessly across iPad, iPhone, Windows, Mac, and the web.
