One way to make power measurement for USB powered devices is to make your own USB cable to allow for current measurement via a multimeter, but if you think it?s just too much hassle, I?ve found and purchased a small test device called CHARGER Doctor that shows voltage and current on a 4 digit display.
The device features a USB female out port, and a USB male input port, that you can place between your USB power adapter, and the cable to your device to alternatively display voltage (4 seconds) and current (9 seconds). It can be used for power consumption measurements, to test if your charger is working normally, or finding out the power adapter that will charge your phone the fastest. It?s said to support measurement between 3.5 to 7V and 0 to 3 A, with an accuracy of +/- 1%.
