The JBL Partybox 310 runs on a rechargeable battery that can last up to 18 hours on a full charge, according to the manufacturer's product description. This should be plenty for most day-long events without needing to plug it in.

However, our research indicates that some folks have faced issues that might affect how long the battery actually lasts. A few people mentioned problems like the speaker not turning off properly or automatically restarting. These glitches could possibly drain the battery faster than expected since the speaker might stay on without you knowing.

There've also been reports of the volume dropping unexpectedly, which can be annoying if you're rocking out to your favorite playlist and have to keep adjusting the volume. These problems seem to be isolated cases, possibly linked to software or connectivity issues.

As a fix, consider checking for any firmware updates via the JBL Partybox app — updates might smooth out these hiccups. If problems keep happening, reaching out to JBL's customer support or exploring warranty options might be worth it. Some have had luck resetting the speaker or checking that all settings are correctly configured.

In the end, the Partybox 310 is built for long playtimes, so don't worry too much about these problems being widespread. Just keep the device charged and make sure the software’s current to get the best out of your battery life.
