About 20% of its capacity.

How long does THE BATTERY last?
This hasn't changed from previous designs. It'll last 40 hours at mid-volume with any SOUNDBOKS. When you turn up to 11, it gives you 6 hours for the SOUNDBOKS 4 and 10 hours for the SOUNDBOKS Go.

Why doesn't my SOUNDBOKS 4 come with a charger?Due to the EU Radio Equipment Directive, the SOUNDBOKS 4 no longer include a charger. This policy aims to reduce electronic waste by encouraging the use of existing USB-C chargers. If you need a charger, you can purchase THE CHARGER separately.
