Startup and shutdown of more phones I got!

I got a dozen old phones from my mom's friends! 9 work, and three don't. The phones that don't work are the iPhone 5c, HTC Evo Shift 4G, and the Samsung Nexus S. The Samsung Nexus S was working in the video, but it blacked out. I thought the battery died, but when I plugged it in, it didn't work anymore. All 12 phones are going to the EcoATM Machine tomorrow.
