Which end of it? The charger or the phone?How to measure voltage at micro usb port on android with multimeter???
That would be a little difficult since the battery voltage in cell phones is about 3.6 volts.......A phone could be giving out 5V, ......
I do not think a cell phone will output voltage on the micro USB connector. It is designed to receive 5 volts to charge the battery.I want to know how much voltage is android giving out???
The USB OTG spec says 4.4V to 5.25V, so the phone obviously needs to do a boost conversion from the battery voltage. Not too difficult with modern minitaturization, but still a hassle, which is why not too many devices have this.That would be a little difficult since the battery voltage in cell phones is about 3.6 volts.
