Stuck at 40% when charging?

I've just bought a UE megaboom and found out that the adapter wasn't working properly so I replaced it.

Now I'm charging it with the LED blinking, however it always says it's charged at 40%. No idea what to do

Answer this question I have this problem too

Is this a good question?

Hey buddy, i got the same problem last week-end, for a Megaboom that i bought only since 3 month and when i called Them (Logitech) they told me one thing to do and it works for me. You have to press at the same time bluetooth button, volume up, and volume down. The speaker will be shutdown and after that you turn on the speaker and you’ll see, the battery will charge until 100%". But the men told me that i had to do those commands with the charge plugged in the speaker. Let me know!

interest thing at the moment. i´ve also a box with this problem. i charge it up to 100% no play after the charge and when i reset the box then she said me 40%. i will try this step and inform you here when its a solution for me. important question. it is important to make this new reset in charge mod? in detail box turn on and with the charge cable or can i make it without the cable?

sorry for my english.

but at last i think its a little problem with the charging platin in the box. i´ve open many boxes and see the black slot from this platin to the mainboard and it was by very many boxes broken and its very difficult to repair this. :-(

small update at the moment. i´ve check the problem with another megaboom. the problem said buetooth but i played music 2 hours then i reset this box and the same problem. normal reset an the box say 40%. but i try the new thing, with bluetooth and + and - but for me the 40% also there. i think its from logitech a function or an normal standard of this capacity status of this box. i will check with another one. then i think its safe with this problem and it is no problem. :-)

when i charge the box normal and i can play the music with full batterie, then it losts i think 2 or 4% and on the next day its the same capacity. i think its the reset function for this problem ;-)

Hi @ dwoodworth.

There is a 2 year manufacturer’s warranty on the product.

I suggest that you verify if the warranty period is still valid for your speaker and if so consult the warranty statement as to what you have to do to make a claim for a manufacturer’s warranty repair or replacement.

Have you tried resetting the Boom2?

  • Turn on your UE Boom holding down the volume down button and the power button at the same time until you hear a sound.
  • Your UE Boom will then turn off. Turn it back on and try to pair it with your device again.

Also how are you gauging the batteries level within an iPhone or Android?

I’m gauging with the speaker itself. It literally tells me 40%

Have you tried updating the firmware? I downloaded the UE Boom app and updated it. Problem solved!

Firmware updated yet it still says 40% . Reset multiple times and charges for hours & even the LED light doesn’t flash while it’s plugged in charging

@AKASH SONETHA - Then your battery is on its last legs.

Hallo everyone! The same problem, now in 2020 with UE MEGABOOM white 2018 model! In my situation the speaker suddenly STOPPED working and when I changed device (I use it in a Macmini and I make a try with an iPhone) it couldn’t play up to the third volume line (if the maximum of volume is 10, my speaker play maximum at 3).

After many many articles, I tried your suggestion:

I pressed the Volume Up and Down and the Bluetooth button at the same time WHILE the speaker was plugged in and it totally closed without coming back AND THEN I pressed the power button with the Volume Down button and everything became absolutely OK!

I hope we will have an Update… This problem scared me as !&&*!

Thank you everyone for your suggestions and help!
