Apple today released the second developer beta of macOS Catalina 10.15.5.
According to Jason Snell from Sixcolors, in macOS 10.15.5 Beta 2, Apple redesigned how macOS manages charging.ย The new battery health management function aims to improve the battery life of the MacBook and reduce aging.
The new battery health management only supports MacBook computers with Thunderbolt 3 connectors.
According to Apple, the purpose of this feature is to reduce the chemical aging of the MacBook battery and extend its long-term life without affecting the daily battery life.
The working principle of this function is to analyze the battery temperature and the charging mode of the notebook computer history-for example, the notebook computer frequently drains most of the power and then fully charges, or it remains fully charged and plugged in most of the time.
In the latter case, battery health management is more likely to stop charging when the battery is not full to extend the long-term battery life.
All charging data on the MacBook is confidential. Unless the Mac chooses to share anonymous analysis data with Apple, all charging data is confidential.
Modern laptop batteries are charged to 100% and stored there for a long time, especially at relatively high temperatures, will greatly reduce the battery life.
Apple decided to adjust the default battery charging behavior of the MacBook so that it will not fully charge the battery too extreme in some cases to extend battery life.
