    Out of the box, the UE Boom speaker comes with the battery around 80-100 percent charged. After that, the average charging time is 2-4 hours. To answer your question, it doesn't really matter how long you leave it plugged in for at first, as long as it charges to 100 percent. And since it is a Li-Ion battery it doesn't even have to charge to 100 percent, you can use it whenever.
