In this episode, Tyler demonstrates how to limit the maximum charge of your Mac's battery to 80, 85, 90, or 95%, useful for prolonging long-term battery health.

To do this, go to System Settings > Battery, click the "Show Detail" button to the right of "Charging," adjust the slider to your desired charge limit, and click Done. Note that the available increments are relative to the slider rather than the battery percentage, meaning setting it to 0% will limit the maximum charge to 80%, 25% will limit it to 85, 50% will limit it to 90, 75% will limit it to 95, and 100% will allow the battery to charge to its full capacity. The set limit is displayed to the right of the slider and is updated as the slider is adjusted.
