According to Jason Snell at six colors, the feature will only be available on Mac notebooks with Thunderbolt 3 ports. For compatible systems, it enables a new default approach to charging and discharging laptop batteries. Apple says thefeature is meant to reduce the rate of chemical aging of the MacBook’s battery, thereby extending its long-term lifespan—but without compromising on day-to-day battery life. Snell says the feature works by analyzing the temperature of the battery over time, as well as the charging pattern the laptop has experienced.
