Apple announced that it has provided a new power management strategy in macOS Catalina 10.15.5 to extend MacBook battery life.
It is well known that the performance of lithium batteries will gradually decrease with the increase of use time, and the charging capacity of lithium batteries will continue to decline during the aging process of lithium batteries.
In the end, the capacity of these lithium batteries may drop to a very low level, affecting users’ use. For this reason, Apple has launched a new power management strategy based on data analysis.
The new battery health management function in macOS 10.15.5 aims to extend the overall life of the lithium battery by reducing the rate of battery chemical aging.
This function is realized by monitoring the temperature history of the lithium battery and the charging mode. According to the collected data, this function will reduce the battery capacity in this mode.
This is based on the results of data collection and analysis, which can ensure that the battery is charged to the optimal level instead of the maximum capacity, thereby reducing battery wear and delay aging.
Although battery health management can extend battery life, it will also lead to longer charging time, so users can also selectively turn off this feature.
When the user upgrades to the latest version, the system will enable the battery health management function by default, and its configuration options are located in the energy-saving sub-options of the preferences.
If the user unchecks the battery health management function, it means that the function is turned off. After the shutdown, the battery charging speed will not change but the battery will be fully charged as much as possible.
Apple also emphasized that turning off this function may increase the aging speed of the lithium battery and reduce its lifespan, so this function will be turned on by default after the system is upgraded.
