My Samsung Galaxy S4 for example won't boot without a battery. Also the battery protection circuit is checked for. To get the phone to boot without battery i had to remove the cell from the battery and then connect a power supply to the leads of the protection circuitry. Not without risks either.
- BizarroLand 4y agoSeems like something that could be solved with a small capacitor bank. I may have to give this a try and see what I can figure out. I figure the input voltage would be somewhere around 5 volts and the expected output current would be 3.3 to 4.2 volts, but I bet a static 5 volts should be fine if the chip only checks to see if there is current.
- jacob019 4y agoI've done this a few times, just an electrolytic capacitor across the battery pins often works.
