Hi all,

I recently bought a new headset (Sennheiser PXC 550-II), and I want to use it with USB C on my smartphone. However, when I plug it in, the battery of my Samsung Galaxy S10 drains to charge the headphones. How can I disable USB discharging (Android 11, root OK) ?

Thanks for your help !

    I think the USB cable is only for charging the headphones.
    You should user the studio cable to get it audio connected to your S10. Fortunately it still has the headphones jack.

    Thank you for your interest in my problem.

    Following some comments found and in order to want to disable the + 5V pinout of the USB socket, I also tried the cable "micro-cable male C to USB-A female OTG" destined for an external DAC, but the same problem happened.

    After hours of research, no solutions finded.

    So, I will stay in jack, because even if I lose the audio controls (and a little background noise that I don't have in USB :( ), my smartphone battery will be preserved.

    I compensate with a 3.5 --> 2.5 jack cable from JBL with microphone and 1 button for "BL E35 / E45 / E55 / E65 / C45".
