    I connected my S8 to my TV over HDMI. I noticed that the batter is draining fast.

    In the menu I see the option "Charge connected device" is selected. I cannot switch to "Charge this phone". It will disconnect from HDMI and after reconnect the option "Charge connected device" is selected again.

    Is the battery draining so fast because the S8 tries to charge the TV? Any solution?


    PS: The cable I use is AUKEY USB C to HDMI

    Uhm sorry but you are entirely wrong. The USB-C supports OTG (adapter is in the box!) and HDMI. I see the mirrored phone display on my TV.
    The S8 shows "Charge connected device" which means it is currently charging the TV. Thats a bug and I do not know where I can report it.

    The "charge the device" choice doesn't apply if the device is a TV (The phone doesn't have anything connected to HDMI pin 14, which is an output pin anyway.) Watch the same thing, without using the HDMI cable, for the same amount of time, and you'll probably see about the same amount of power drain.
