Apple's macOS 10.15.5 Catalina To Add Functionality To Prolong MacBook Battery Lifespans
Apple is bringing similar functionality to Macs with a feature that will be called Battery Health Management according to The Verge, and will be found in Energy Saver Preferences within Settings. The purpose of the feature is to prevent premature aging of the batteries inside MacBooks, which is key because the batteries are not user-replaceable. All lithium-ion batteries age over time, reducing overall capacity. However, the rate at which this aging happens can be exacerbated by certain activities.
For example, keeping a charged battery at 100% can cause undue strain, and Apple is looking to avoid this. The Verge writes:
in certain cases, seeing 100 percent battery life in your menu bar may not necessarily mean it’s the maximum your battery could charge to. Instead of meaning that it’s charged to 100 percent of what the battery could take, it will now mean it’s charged to 100 percent of what the battery should take to maximize its lifespan.
According to the report, the new features will only be implemented on MacBooks that have Thunderbolt 3 ports, and will only be targeted at a subsegment of devices the Apple feels would benefit most from this battery management scheme. The feature will be enabled by default with macOS Catalina 10.15.5, but it can be disabled by the user if they wish.
