So I bought JBL Xtreme a week ago. I've tested it and all I got is 7-7.5 hours on 76% of volume. Is it okay ? I thought it would play longer than that, how do I get 15 hours ? Also another issue is that JBL connect (app) shows that it is not fully charged (green line is not fill to the end) . I don't see any issues while charging, it reaches 5-th led and than all leds turn off (I read somewhere that this is normal). Hope I will get answer, thank you.
