Mac and iOS Battery Health: A New Era of Control
Apple continues to refine its approach to battery health, and the latest iOS 26.4 and macOS 26.4 betas demonstrate a commitment to giving users more granular control. The expansion of the Charge Limit feature – previously available on iPhone and iPad – to Mac devices marks a significant step forward. This feature allows users to cap charging at 80% or 100%, aiming to reduce battery degradation over time.
Why Charge Limit Matters
Lithium-ion batteries, like those found in iPhones, iPads, and Macs, degrade over time with each charge cycle. Keeping a battery consistently at 100% can accelerate this degradation. By limiting the maximum charge, users can potentially prolong the overall lifespan of their device’s battery. Apple notes the system will still occasionally charge to 100% to maintain accurate battery health reporting.
Shortcuts Automation Takes Battery Care to the Next Level
The integration of Charge Limit into the Shortcuts app is a powerful addition. This allows for automated battery management based on user-defined triggers. For example, a user could create a Shortcut that automatically enables Charge Limit when a Mac is connected to a power source at home, and disables it when the device is unplugged.
Other Updates in iOS 26.4 and macOS 26.4
Beyond Charge Limit, the betas introduce several other enhancements. MacOS 26.4 includes end-to-end encryption for RCS messaging, a redesigned wallpaper settings section, and new battery charge options. IOS 26.4 brings improvements to Apple Podcasts, Apple Music, and Messages, including encrypted RCS messaging.
