jbl xtreme 3 stopped turning on battery

So, I've got jbl xtreme 3 but on day it stopped turning ON on battery, it only lights up the power button for around 30sec, then it's turning OFF. When i plug it to the power its all fine even when i disconnect it from the power. The moment i turn it off its all over again it starts in the same way. Its not in lock/aux only mode, I've got my suspici on strange combination of buttons that i may pressed before this happened its the bluetooth botton, vol- and the partyboost connection. I have no idea what to do.
