When I read news about things I actually understand I realize that I can ' t rely on news for things I don ' t really understand . <| sep |> I have a new Hero 5 Black , and I took it on a bike ride to try it out for the first time . I started out with a full battery , and started recording 1080 p video when I left the house . I checked the battery periodically by turning on the LCD , and noticed that it got to 77 %, then stayed there . After about 40 minutes of being stuck at 77 %, it made a few angry beeps , and shut off . I turned it back on , and got an low battery message , with the battery at 0 %. Is there something obvious I ' m missing ? Is this a known issue ? Or should I exchange it ? <| sep |> This hiatus is going to be unbearable if MoringMark keeps posting these kinds of comics every day until the next episode . EDIT Also gangnam style Janna . I didn ' t know I needed this .
