One of the main news that was leaked in the beta version released by Apple is that the version of macOS Catalina 10.15.5 beta add a function called Battery HealthManagement, With which the team will manage the battery in a specific way so that it works much longer.
It has always been said that MacBook batteries are different from other Apple devices because they carry out a different management than an iPhone, but in reality they are increasingly similar and that is why Apple wants to take care of the battery with this new tool. The bad thing is will not be available to everyone the teams…
This battery management will be available on many of the MacBooks that we have in the Apple product catalog, but not all of them. Logically Apple wants to offer a positive experience with this function and adding it to all models compatible with macOS Catalina would possibly not be the right thing to do since there are very veteran MacBooks that support the OS but logically this option may not be useful due to the state of the battery or reasons unknown to us.
So in principle and if the thing does not change in the following weeks the new function Battery health managementIt will work on MacBook Pros from 2016 and later and MacBook Airs introduced in 2018 and later. Basically all those that work with the Thunderbolt 3 port. So while it is true that the number of computers that will support this function is extensive, it will not be available in all.
