That’s not the point. It’s bad for lithium batteries to be full all the time. That’s why iPhones wait to charge the last 20% until right before you wake up, and why Samsung phones have the option to limit charging to 80%. However, the most ideal charge for battery health is between 50-60%, so if you leave your Deck plugged in all the time, you should limit the charging to that for maximum battery life, and only charge it higher when you know you’re going to be needing it.
