# Charge Limit on Mac: Enhancing Battery Health
The Charge Limit function, which allows individuals to establish a maximum charge level for their devices, represents a notable improvement in battery management. Originally available solely on iPhone and iPad, this function has now been made available to Mac users with the launch of macOS 26.4.
## Understanding Charge Limit
Charge Limit permits users to define a maximum charge level, aiding in prolonging battery lifespan by lessening the pressure of charging to 100%. Initially, the threshold was fixed at 80%, but with the advent of iOS 18, users can now select options between 80% and 100%. This adaptability is especially advantageous for users who may not require their devices to be fully charged at all times.
When the Charge Limit is turned on, the device will cease charging just before the set limit, thus reducing battery degradation. Nevertheless, Apple indicates that occasionally the device may charge to 100% to preserve precise battery state-of-charge assessments.
## How to Enable Charge Limit on Mac
To activate the Charge Limit function on your Mac, adhere to these instructions:
1. Open **Settings**.
2. Go to the **Battery** section.
3. Tap the “info” icon next to “Charging” to choose your preferred charge limit.
This straightforward procedure empowers users to effectively manage their battery health.
## Charge Limit in Shortcuts
Alongside manual configurations, the latest iOS 26.4 and macOS 26.4 betas incorporate the functionality to automate the Charge Limit feature via the Shortcuts app. This allows users to create routines that automatically modify the charge limit based on their usage habits, improving ease and battery management.
## Conclusion
The Charge Limit function is a fantastic tool for users aimed at prolonging their battery health, particularly for those who often utilize their devices while connected to power, like MacBook users at desk setups. By regulating charging levels, users can ensure their batteries stay healthy over time. As this function gains more widespread acceptance, it will be intriguing to observe how users integrate it into their daily activities.
