macOS 26.4 brings a long-awaited feature to the Mac: Battery Charge Limit. This functionality, previously exclusive to iPhone and iPad, lets users set a maximum charge threshold to help extend battery health over time. The update arrives as part of Apple's ongoing efforts to improve device longevity and sustainability.

The Charge Limit feature works by capping the battery's maximum charge percentage, typically around 80%, to reduce chemical aging. This helps prevent the battery from staying at 100% for extended periods, which can degrade capacity faster. Users can now apply the same battery-preserving strategy to their MacBooks that they've been using on their iOS devices for years.

Apple's decision to bring Charge Limit to the Mac addresses a common pain point for laptop users who keep their devices plugged in frequently. The feature integrates with macOS's existing battery management tools and gives users more control over their device's long-term health. By extending this iOS feature to the Mac, Apple creates a more consistent battery management experience across its ecosystem while helping users maximize the lifespan of their expensive hardware investments.
