About Optimized Battery Charging and Charge Limit on Mac
To improve the lifespan of your battery, Optimized Battery Charging allows your Mac to learn from your daily charging routine so that it can delay completing a full charge in certain situations. And with Charge Limit, you can limit what your Mac considers a full charge.
If "Charging On Hold" or "Charged to [%] Limit" appears in the battery status menu
, your Mac is using Optimized Battery Charging or Charge Limit.
How your Mac battery ages
A battery’s lifespan is related to its chemical age, which is more than just the length of time since the battery was assembled. A battery's chemical age results from a complex combination of factors, including temperature history and charging pattern. All rechargeable batteries are consumable components that become less effective as they chemically age. As lithium-ion batteries chemically age, the amount of charge they can hold diminishes, resulting in reduced battery life and reduced peak performance.

Optimized Battery Charging
Requires macOS Big Sur 11 or later
Optimized Battery Charging is designed to reduce the wear on your battery and improve its lifespan by reducing the time that your Mac spends fully charged. It uses on-device machine learning to learn your daily charging routine so that it can delay charging past 80% in certain situations, such as when it predicts that your Mac will be connected to power for an extended period of time. Optimized Battery Charging aims to ensure that your Mac is fully charged by the time it expects you to need a full charge. To limit what your Mac considers a full charge, you can also set a Charge Limit.
When charging past 80% is delayed by this feature, "Charging On Hold" appears in the battery status menu. If you need your Mac to be charged to 100% sooner, choose "Charge to Full Now" from the menu.
To turn this feature off or on, use the Optimized Battery Charging setting in Battery settings. For example, in macOS Ventura 13 or later:
From the Apple menu , choose System Settings.
Click Battery in the sidebar.
Click the info button
next to Charging (or Battery Health).Turn Optimized Battery Charging off or on.
When you turn it off, you can choose whether to turn it off only until tomorrow.
When using macOS Tahoe 26.4 or later, you can also set a charge limit.
Click Done.
Charge Limit
Requires macOS Tahoe 26.4 or later
Use Charge Limit to set a limit on what your Mac considers a full charge. Your Mac will charge to within a few percentage points of the charge limit, then stop charging and show "Charged to [%] Limit" in the battery status menu. If the battery charge level drops more than 5% while connected to power, charging resumes, again charging to within a few percentage points of the limit.
If your Mac is charged to the limit but you need it to be charged to 100%, choose "Charge to Full Now" from the battery status menu.
To set a charge limit:
From the Apple menu , choose System Settings.
Click Battery in the sidebar.
Click the info button
next to Charging.Choose a Charge Limit setting between 80% and 100%.
Click Done.

Whether using Optimized Battery Charging or Charge Limit, your Mac will occasionally charge to 100% to maintain accurate battery state-of-charge estimates.
