What's the use case for limiting your device's charge at 80%? 🤔

Protecting your battery life. Charging to 100% drains it dramatically over time.

Right. As the battery nears capacity filling, the BMS has to work harder to find space for the electrons to go, so this adds significant wear and tear to the physical elements.

Latest GrapheneOS build has an option to cap your charging % to 80%. Once it reaches 80%, it'll start drawing energy from the wall instead of battery.

TIL.
