What does it do?

Good question. It gives you notifications about when to plug and unplug your charger.

Cool, but why?

Batteries loose the most capacity if the voltage difference is high, or staying at 100%. Hence, if you you use your laptop most of the time plugged in, it will decrease the capacity of the battery quicker than normal.

To sum up, you should not:

• Charge you battery regulary over 80-90%
• Discharge under 30-40%
