Does your UE Boom 2 portable speaker lose battery quickly or refuse to charge? UE Boom speakers are susceptible to a range of problems that could cause them to stop charging or lose battery power too quickly. Check the following possible causes to identify and solve the problem.

If your UE Boom 2 speaker is simply not turning on, see the UE Boom Won’t Turn On problem page, instead.



If your UE Boom 2 speaker is not charging, there may be a problem with the speaker’s charging cord or the power outlet. First, plug in the speaker using a different charging cord to see if the original cord was the problem. If the speaker is still not charging, plug the charger into a different power outlet, as the outlet itself could be the problem.


If the speaker is refusing to charge, it may need a factory reset. Press and hold down both the volume button and the power button for about ten seconds or until you hear the speaker make a sound. After the sound, the speaker should turn off. Now, try turning the speaker on again.


If you have tried charging and resetting your speaker, and it will still not turn on, you may be dealing with a faulty USB port. Try using the speaker’s USB cable and plugging the UE Boom into your computer (note that software may automatically install for the USB connection). Try turning your speaker on while it is connected to the computer, then disconnect the speaker and turn the power off. Then, try turning the speaker on again.

If you have followed these steps and the speaker still refuses to charge or turn on, you may need to replace the speaker’s USB port. Use the UE Boom 2 USB Port replacement guide to replace the speaker’s USB port.


If you have charged the speaker and it still will not turn on, your speaker’s battery may have reached the end of its lifespan. Use the UE Boom 2 Lithium Battery replacement guide for instructions to replace the speaker’s battery. Note that replacing the battery will void the speaker’s warranty.


If you accidentally dropped your UE Boom speaker in water, you may want to turn the speaker completely off, disassemble it, and thoroughly dry the internal components. If the speaker still has trouble charging after you have dried its interior and reassembled it, you may need a new motherboard. Use this UE Boom 2 Motherboard replacement guide to replace the speaker’s motherboard.
