How can I see how much electricity a device connected via USB is drawing from my phone?
I have connected a device to my phone via an USB cable so that it receives some electricity from the phone. How can I see how much electricity a device connected via USB is drawing from my phone?
I use Android 12 with a Google Pixel 6
For little money there are USB-Amperemeters. They measure the current [mA] that flows through them and also cummulate the energy, measured in milliampere-hours [mAh]. Just search for Usb Ampmeter or Usb Powermeter.
I don't know about your cabling, but probably you will need an adapter additionally, as the ones i know use standard size Usb Ports.
