We’ve had some reports about abnormally fast battery drainage while storing the camera with the Unleashed plugged. There is one known bug that may be causing this issue:
Often people insert a freshly charged battery before storing the camera – that’s when this bug occurs. To avoid this you need to turn the camera on and off after changing the battery, otherwise it results in high drain.
We’ve already been able to resolve this in the Beta. You can join it if you use iOS/Apple. There are many new features and many bugs are already fixed there too – you can find more info on that and how to join here.
