Apple continues to be sued for deliberately slowing down the iPhone, which the company once explained by the desire to extend battery life. However, few people noticed that the company uses a similar Mac computer scheme: if the system notices that the battery life has dropped, it deliberately prevents the computer from operating at maximum power. Apple legalized this feature last year by adding a mechanism to macOS 10.15.5 optimized charging. It extends battery life and limits the supply of power when a certain battery level is reached, and reduces the computer’s peak power. Many people disable this feature, but in macOS 11.3, it seems to be very useful.
Apple continues to make charging smarter MacBooks
The developers found in the beta version of macOS 11.3 mention a new feature with which optimized charging MacBook can learn depending on the daily routine user. To do this, it will be enough for him to add to his calendar, for example, a meeting at 14:00, and the system will understand that the laptop needs to be charged up to 100% by this time. It turns out that macOS will analyze the calendar and, depending on this, select the optimal charging mechanism at one time or another. Since many Mac owners use a built-in calendar to plan their day, this can be helpful.
The system will analyze the calendar and your geolocation.
What is Optimized Charging on Mac?
With Optimized Charging enabled, macOS often deliberately does not charge the laptop to 100%, limiting the charging process to 80%. This occurs when the system predicts that the user will be connected to a power source for an extended period of time. macOS delays the completion of charging until the user needs to use the MacBook on battery power.
For example, if the user keeps the computer connected to a power outlet at all times, optimized charging will automatically limit the power supply to avoid satiety. And if the user uses the laptop from charging to charging, then connecting it to the power supply, then turning it off, the mechanism will prohibit the battery from charging up to 100%, setting the unit at a lower level to avoid degradation.
With a new feature in macOS 11.3, Optimized Charging can be even smarter, so you don’t have a situation where your MacBook is 80% charged instead of 100% at the most inopportune moment. Although in the MacBook Air case with the M1 chip (and even more so the MacBook Pro), this is not so relevant.
How to Disable Optimized Charging on MacBook?
If you wish, you can disable the battery management function altogether. To do this, follow these steps.
- Discover System settings.
- Go to the Battery.
- Uncheck the box Optimized charging.
Disable this feature only in extreme cases.
If you do not want the system to limit the computer’s maximum power when the battery condition deteriorates, you can also control this parameter. To do this, in the same section, click “Battery Health” and uncheck the box next to “Manage battery life.“
If this checkbox is checked, the maximum power of the laptop may be limited.
Limiting the supply of energy can really help conserve its life. The same charging method is available, for example, to owners of Tesla electric vehicles. According to Elon Musk, it prevents early aging of the battery and prolongs its life many times. There is nothing worse than satiety and even full saturation.
