Recently I found an iPhone 8 and took it home. Tried booting it up and of course it asked me for iCloud account, so I put the phone aside and forgot about it. Today I decided to try and bypass the iCloud, but the iPhone doesn't seem to charge. It's like completely dead. Weirdest part is that when I connect the dead phone to my PC, my computer instantly turns off. Wtf? Do you have any idea what's going on?
