is there any way to make a usb cable that cuts the power when the phone gets to 100%?
https://www.kickstarter.com/projects/evolvedcharger/usbidi-the-worlds-most-intelligent-charger-everHow will the external circuitry determine the state-of-charge of the internal battery when the battery terminals are not accessable without cutting holes in the cell phone?
Many phones flash up a battery full indication - a photo cell could detect that and trip a breaker circuit.i want to do it in the cable. so that the phone will fell disconnected
Or a comparator (no microcode).Sounds like a microprocessor (powered continuously by the USB) monitoring an inline current-sensing resistor and a MOSFET to disconnect the power when the charge current level drops.
