I bought a BTR15 last weekend. For some reason when used as a USB DAC the battery would lose an entire 20% of battery the moment I plugged in the fiio OTG cable. And then very quickly would run out of more battery in 20% increments over half an hour until it died. I returned it and ordered a replacement from Amazon customer service. I am hoping I got an extremely defective product and it’s not like this normally. Anyone else having this problem?
