Charge Limiters for Increasing the Battery Life of Plugged-In Laptops on macOS

When using a MacBook primarily plugged into a charger, it's often beneficial to limit the battery charge to around 80%. Charging up to 100% regularly can lead to increased wear on the battery, reducing its long-term lifespan. By keeping the battery charge capped at 80%, you can reduce the stress on the battery, which helps to maintain its health over time, especially for devices that are always connected to power.
