Hmm just wanting to inquire, I bought the govibe vestamp (amplifier only version) recently, and the battery seems to last around 10 hours per charge. It takes 4hours+ to full charge (atleast thats what I think as the red LED light goes out) and within a week with less than 10 hours on the clock, boom its dead. I got to recharge it almost every week. Is this the normal battery life?
