In macOS Big Sur and later, Apple has included a smart feature designed to learn your charging habits and extend battery life by reducing the time it takes for your Mac notebook to fully charge.
When this feature is enabled (by default on Macs with Apple Silicon or T2 Security Chip), your Mac attempts to learn your charging routine to intentionally ensure that your Mac is fully charged when unplugged electricity. Once you establish your daily habits, your Mac will delay charging past 80% in some cases.
Of course, this feature can become cumbersome if you don't have a consistent routine. For example, you might disconnect your Mac after being away from your desk for an extended period of time, then discover that it isn't fully charged when you need it most.
However, if you need to disconnect your Mac immediately, this isn't any solution and you'd be better off turning off Optimized Battery Charging entirely. The following steps show you how.
Disable optimized battery charging
- Click the Apple symbol () in the corner of the top menu bar, then click "System Settings"...
- Select Battery in the sidebar menu.
- Click the button in the Information (i) Battery Health section.
- Click the switch next to "Optimize battery charging" to turn it off.
- Select Close or Close until tomorrow.
Check the Battery Status results. If it is normal, then your battery health is good. This may be the case even if the included maximum capacity reading no longer reads 100%. This is because the batteries used in Mac laptops are designed to retain up to 80% of their original capacity at a maximum number of cycles when operating under normal conditions.
However, if your Mac's battery is below 80% of its maximum capacity, that's a sign that it needs service, and you may have experienced a significant decrease in battery life.
Every new Mac purchased from Apple comes with a one-year warranty that includes coverage for defective batteries. If your Mac is out of warranty and the battery is in poor condition, Apple offers battery service for a fee.
The above are the details of turning off optimized battery charging in macOS. For more information, please pay attention to other related articles on the PHP Chinese website!
