 <img width="300px" align="right" src="./screenshots/tray.png"/>This tool makes it possible to keep a chronically plugged in Apple Silicon Macbook at `80%` battery, since that will prolong the longevity of the battery. It is free and open-source and will remain that way.

 > Want to know if this tool does anything or is just a placebo? Read [this excellent article](https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries). TL;DR: keep your battery cool, keep it at 80% when plugged in, and discharge it as shallowly as feasible.

+### What distinguishes this project from Optimized Charging?
+
+Optimized Charging, a feature that is built into MacOS, aims to ensure the longevity and health of your battery. It does so by "delaying charging the battery past 80% when it predicts that you’ll be plugged in for an extended period of time, and aims to charge the battery before you unplug," as explained in [Apple's user guide](https://support.apple.com/en-ca/guide/mac-help/mchlfc3b7879/mac#:~:text=Optimized%20Battery%20Charging%3A%20To%20reduce,the%20battery%20before%20you%20unplug.).
+
+Additionally, Optimized Charging uses machine learning to decide when the battery should be held at 80%, and when it should become fully charged. If your Mac is not plugged in on a regular schedule, optimized charging will not work as intended.
+
+This app is a similar alternative to Optimized Charging, giving the user control over when it is activated, what percentage the battery should be held at, and more.
