Some phones are too power hungry to run off a dyno. On all but the flattest ground, with my Samsung Galaxy S5 connected to my SON28 + USB-Werk it bounces in and out of charge mode and quickly loses power even with the display off.
It charges OK in "low power mode" with no apps, black and white display, and dimmed screen although that's not useful for navigation.
