POWER DRAIN ISSUE.
Not sure if this has already been addressed but here goes,
I've got a Samsung Galaxy S4 running USB Audio Player Pro 1.0.9, OTG'd to a Fiio E17. The issue is the phone's power is being used really quickly whilst the E17 doesn't appear to be using any power at all....as if the phone is powering the E17!
Has anyone else had a similar experience? if so, is there a solution as at the moment it makes the setup I have is impractical as the phone is drained of power in approx. 2 hours : (
I also got a power drain issue.
My chain: Galaxy S3 (Android 4.1.2) -> Poweramp -> Fiio E18.
This AMP/DAC is designed to not drain power from the power, but I notice a battery drain also if I turn off the E18 but leave the USB OTG cable connected.
I dont' know if this is normal or not.
The phone must do something while the cable is connected, I think to test if the external device is alive, is right?
There is a way to avoid this?
Yes I know that it can be enough to disconnect the cable, but is not always easy when both this device are in my pockett...
