Best answer: The brand new UE Megaboom 3 has the longest battery life — up to 20 hours. But the other Boom speakers aren't far behind.

The biggest speaker gets the biggest battery

The UE Megaboom 3 is UE's second largest speaker (behind the Megablast), but it actually has the longest battery life of any UE speaker at 20 hours.

Battery life will vary, however, depending on usage, settings, and environmental conditions. If you're listening at full volume all day long, then battery life will be shortened. Also, if it's incredibly hot or incredibly cold outside and you're using the speaker, battery life may vary.

The differences between speakers is minimal

Though the Megaboom 3 (and first-generation Megaboom) has the longest battery life, it's only 5 hours longer than the Boom 3 (15 hours). And the UE Wonderboom has a 10-hour battery life.

In other words, if you're looking for a long-lasting, portable, waterproof Bluetooth speaker, you really can't go wrong with any of the Boom line.
