The Cupertino tech giant recently seeded macOS Big Sur 11.3 beta 2 to developers for testing, and now an improved ‘Optimized Battery Charging’ feature on the Mac is discovered. The operating system’s code reveals that users will be able to charge their Macs to 100%, hours before a scheduled meeting or event if it’s logged-in to the Calander app.
After releasing it on iPhone and iPad, Apple introduced the Optimized Battery Charging feature on Mac in 2020. As a feature of battery health management introduced in macOS Catalina 10.15.5., the feature does not fully charge the Mac to reduce the impact of chemical aging and prolong the battery’s lifespan. The release notes read,
Battery health management is designed to improve your battery’s lifespan by reducing the rate at which it chemically ages. The feature does this by monitoring your battery’s temperature history and its charging patterns.
Based on the measurements that it collects, battery health management may temporarily reduce your battery’s maximum charge. This happens as needed to ensure that your battery charges to a level that’s optimized for your usage—reducing wear on the battery, and slowing its chemical aging.
An improved Optimized Battery Charging discovered in macOS Big Sur beta 2
Enabled by default on macOS Big Sur, the Optimized Battery Charging feature prevents battery damage in times when the user has plugged the Mac to power for a long period by powering the battery up to 80%. Now, even with the Optimized Battery Charging feature enabled, MacRumors reports that three hours before the start of a scheduled Calendar event, the macOS Big Sur 11.3 will fully charge the Mac even when the Battery health management feature is enabled.
