The newly introduced Charge Limit feature on macOS 26.4 allows users to set a preferred charging threshold, with options ranging from 80% to 100%. This functionality was initially available only on iPhone and iPad, but it has now been extended to Mac devices, enhancing battery longevity by preventing constant full charges.
Users can activate the feature through the Battery section in Settings. While Charge Limit will reduce charging to the specified level, Apple indicates that devices may occasionally charge to 100% to ensure accurate battery state-of-charge readings.
The latest betas for iOS and macOS also integrate Charge Limit within the Shortcuts app, permitting users to automate their settings. This feature is particularly beneficial for MacBook users who frequently remain connected to chargers at their workstations.
