Better late than never I bought my Mojo 2015 and until today I still love it and the battery (no replacement) is still pretty decent lifetime with approx 5 hours (my usage @ 3 Vrms output to STAX ESL IEM driver unit).

@ h1f1add1cted thanks I've read about users reporting the battery life issue ..did you use it daily or so ?

I had the mojo (mobile joy) twice and sounds great as a transportable device but a total let down as a portable. The issue I had with both units was noise when my mobile was in and out of network. something like rf noise with clicks and pops. As such the mojo failed miserably to live up to the “mobile joy”.

not happening to me at moment with Lgv40 ..it might be related to network/ conditions (?). I can test it with Samsung Note10 too

@boodi i owned two and had this issue with both.

same mobile phones or different ?

@boodi i have an iPhone 7

Maybe the phone . Who knows. I will try the Samsung note10 too

@boodi it depends, mixed usage, sometimes a few days in row, sometimes for many weeks not in use. I would say I'll use my Mojo at least 90 days per year since 2015. My charging is always use up to 90% of usage, so around 10% bettery left and than full charge afterwards. I'll never charge the Mojo like 50% or less battery left.
