MacBook Battery Health Boost: New Charge Limit Arriving Soon
17 Feb
Summary
- New macOS feature limits battery charge to preserve MacBook health.
- Users can set a hard limit between 80% and 100% in 5% increments.
- The feature is expected in the upcoming macOS Tahoe 26.4 update.
Apple is preparing to introduce a new battery charge limiting feature for MacBooks, designed to enhance long-term battery health. This upcoming functionality, discovered in the macOS Tahoe 26.4 beta, aims to mitigate the negative effects of consistently charging to full capacity.
The feature, named Charge Limit, operates independently of the existing Optimized Battery Charging. It allows users to establish a fixed maximum charge level, selectable in 5% increments between 80% and 100%. This hard limit ensures the battery will not exceed the chosen threshold unless manually overridden by the user.
This new charge limiting tool is particularly beneficial for users who frequently keep their MacBooks plugged in. By preventing the battery from reaching 100% regularly, it can help extend its overall lifespan. The feature is expected to be integrated into the official macOS Tahoe 26.4 release, with rumors pointing to a potential rollout by the end of March.
In addition to the battery feature, macOS 26.4 beta also restores the compact tab bar option in Safari. Furthermore, it will begin warning users about applications running via Rosetta 2, as these will become incompatible with future macOS versions starting with macOS 28.
