The Ultimate Ears WONDERBOOM 4 has up to 14 hours of battery life on a full charge, according to the manufacturer. That's a nice bump from earlier models, so it's perfect for a day at the beach or a small get-together without worrying about charging it.
Our research shows that the battery life is something a lot of folks really like about this speaker. It's super handy if you’re out and about where you can’t charge easily.
It's also waterproof and durable, which makes it awesome for outdoor adventures and traveling.
Just a heads up, it charges via a micro-USB port. Some might find this a little old-school since many devices use USB-C now, but it’s still pretty manageable.
The good news is it doesn’t take forever to charge and gets back to playing tunes pretty quickly.
As a quick tip, keeping the volume at a moderate level helps the battery last longer. Cranking it up will drain it faster, so adjust as needed to get more playtime.
Overall, the WONDERBOOM 4 is a great choice if you're looking for a Bluetooth speaker with solid battery performance, whether you're inside or out.
