Every rechargeable battery wears out a little with each charge cycle, and your MacBook is no exception. Heat, time, and charging habits all contribute to what Apple calls chemical aging — the gradual loss of maximum capacity. To fight back, macOS includes a feature designed to slow that aging process down. On Intel-based MacBooks it is called Battery Health Management, while Apple silicon models use Optimized battery charging (with an optional 80% charge limit). Both do the same job: they study how you use and charge your Mac, then cap the maximum charge or delay charging past 80% so the battery spends less time sitting at full voltage, which is what stresses lithium-ion cells the most.
The feature is switched on by default on new Macs, but it is worth checking — especially if you bought your MacBook second-hand, restored it from a backup, or ever toggled battery settings in the past. The steps below take less than a minute, and they work on every MacBook running macOS Catalina 10.15.5 or later.
How to enable Battery Health Management on MacBook
On macOS Ventura, Sonoma, Sequoia, and later
- Click the Apple menu in the top-left corner of the screen and choose System Settings.
- In the sidebar, click Battery.
- On the right, next to Battery health, click the info (i) button.
- On Intel-based MacBooks, make sure “Manage battery longevity” is turned on. On Apple silicon MacBooks, choose Optimized battery charging — or select the 80% limit if you want the strictest protection and rarely need a full charge. (The 80% limit is ideal if your MacBook spends most of its life on a desk, much like the 80% charging limit Apple added for iPhone 15.)
- Click Done, then close System Settings. The change takes effect immediately — no restart needed.
On macOS Monterey and earlier
- Click the Apple menu and choose System Preferences.
- Click Battery, then select Battery in the sidebar.
- Click the “Battery health…” button.
- Tick the box for “Manage battery longevity” and click OK.
That is all there is to it. From now on, macOS will occasionally hold your maximum charge below 100% based on your routine and the battery’s temperature history. If you ever see your Mac stop charging at, say, 85–90% even though it is plugged in, that is the feature working as intended — not a fault. (iPhone owners see similar behavior when iOS shows “Charging On Hold”.)
If it still doesn’t work
First, confirm your Mac actually supports the feature: Battery Health Management requires macOS Catalina 10.15.5 or later and a MacBook with Thunderbolt 3 ports. If the “Battery health” row is missing entirely, update macOS via System Settings > General > Software Update. Second, check the battery’s condition in the same Battery settings pane — if it says “Service Recommended”, no software toggle can undo physical wear, and you should have the battery evaluated following Apple’s battery health management guide. Finally, if the toggle flips back off on its own, restart your Mac and try again; a pending update can occasionally reset power settings. And if you want your MacBook to stay awake longer between charges for other reasons, see our guide on how to keep your Mac from going to sleep.
Frequently asked questions
Does Battery Health Management reduce how long my MacBook lasts on a charge?
Slightly, yes — and that is by design. By capping the maximum charge, the feature trades a small amount of daily runtime for a significantly longer overall battery lifespan. Most people never notice the difference in practice.
Should I turn Battery Health Management off?
Apple recommends leaving it on. Only consider turning it off if you regularly need every last percent of capacity — for example, long flights without power outlets. You can re-enable it at any time by following the steps above. Video walkthroughs of the whole process are also easy to find on YouTube.
Conclusion
Battery Health Management is one of those set-and-forget features that quietly adds months — potentially years — to your MacBook’s battery life. Check that it is enabled using the steps above, leave it on, and let macOS handle the chemistry while you get on with your work.
