The Charge Limit feature, which allows you to set a maximum charge to extend battery life, was previously only available on iPhone and iPad.
Fee limit on Mac
Charge Limit is a feature that allows you to determine the maximum charge level of your device. At first it was limited to 80%, but with iOS 18 it was expanded to include options between 80% and 100%. Now, with the first beta version of macOS 26.4, Mac users can now specify a charge limit between 80% and 100%:
When the charge limit is enabled, your device will stop charging within a few percentage points of the set limit. This will help improve battery life by reducing the strain caused by constant charging to 100%. However, Apple acknowledges that your device will occasionally still charge to a full 100% in order to “maintain accurate estimates of battery charge.”
You can enable the charge limit on your Mac by opening Settings, going to the Battery section, and clicking the “info” symbol next to “Charging.”
Fee limit in Agents
In addition, the new iOS 26.4 and macOS 26.4 betas bring a fee limit to the Shortcuts app. You can now automate setting your fee limit:
Wrap
A battery charge limit is a great way to extend your battery life if you’re not a heavy user or use the charger often. I think this will be especially useful on MacBooks as they are often used on desks where you can easily plug them in. Are you using a charge limit on your devices? Let us know in the comments!
