"...a former store manager wrote that "the iPod hardware they used as on the floor scanners for employees died quickly and there was no way of swapping in new batteries"
And how many employees were reprimanded for not plugging them in to recharge? A similar situation happened at a store close to me. A friend said the morning/afternoon shifts would screw around and not recharge devices. Leaving the night crew having to wait their turn for the only remaining device working. Why was this happening?....
1) No one plugged it in to recharge.
2) The recharge cord wasn't plugged in because the employee removed it so they could recharge their own phone. (Hey, Pokemon Go takes up a lot of juice during an eight hour shift. And no, I'm not kidding. This was actually being done by the same employees who were also [see #1 & #3].
3) When they were fully charged the powerstrip would be turned off. And then forgotten to be turned on again. In order to save energy. "Also turn the lights off when you leave the room." Even though people are in and out all day. And it take more power to turn it on/off 30x then it would use if you just left it on.
Also you notice managers won't lose their iPhones.You know, the ones they probably use for Pokemon Go. ;)
