It’s a known fact that smartphone batteries have a limited number of charge cycles and eventually, they will give out. Back in 2017, Apple admitted that it slowed down older iPhones to prevent random shutdowns as a result of aging batteries. Although the battery management system was introduced to help users, they weren’t thrilled and Apple received flak for it. That’s all behind the Cupertino giant now as the iPhone 11 features include a more intelligent battery management system to take care of the issue.

The iPhone 11 features a new software and hardware battery management system that minimizes the effects of an aging battery on the performance of the device. This system monitors the power requirements of the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max in real-time and manages performance accordingly. This automatic system is always on and works round the clock to optimize performance in relation to the withering battery. The important details have been published on the company’s support page.
