It may sound strange that the calendar on our Mac with macOS Big Sur is linked to the battery charge, but it makes sense and it can certainly be very important for users. Right now the optimized load on Macs with macOS Big Sur can be managed by entering the System Preferences within the Battery section.
There we can adjust the days we want to charge the Mac and it allows us to program schedules so that - as long as we have the equipment plugged into the charger - it adapts to our charging requests. We can manage the load by days or even weekends, hours, etc. Well it seems that in the beta version released yesterday for developers it has been detected a new function that will allow the team to optimize the load in the event that we have an event on the calendar.
In this way, when we leave the equipment connected to the charger and it detects that we have an event scheduled rIt will charge automatically so that we do not run out of battery on the day of the event. This option is currently available in the beta version of macOS Big Sur 11.3 and will allow 100% loading three hours before the start time of the scheduled event.
These options allow, in addition to not having scares when holding a meeting, presentation, work and others, improve the useful life of the battery of our equipment. Thus, any event that appears in the calendar will activate the charge automatically as long as the user has activated the optimized battery charging function. All MacBooks - with an Intel or M1 processor - that have macOS 10.15.5 or later installed have this optimized battery charging feature It helps reduce battery drain.
