Steal Your Friend's Battery With This Game

Steal Your Friend's Battery With This Game ⚡ Bro made a game to steal battery from your friend. Just connect two phones with USB-C and start tapping like your life depends on it. Lose, and your battery really drains. Want to play? Github repo is pinned below 👇 How Does It Work? The two phones are connected with a USB-C cable, which lets each phone choose whether to receive power (called "Sink") or give power (called "Source"). Whoever is winning the tapping battle becomes the Sink and charges. Whoever is losing becomes the Source and drains. This is usb-c power delivery in action - same tech as reverse charging and phone-to-phone power share. The catch from the build: the giving phone loses about 1500mA, while the receiving phone only gains about 400mA. So most of the power is lost along the way. That's real phone battery drain physics, explained as usb power delivery explained for makers.
