I got an Nexus 5 years ago with Qi wireless charging and strategically placed charging pucks on my desks at home and work, nightstand and car console, later replaced the 5 with a Nexus 6 and added in a Nexus 7. Never worried about battery, just put the phone down whenever I was in those places. Why this hasn't caught on is beyond me. I'm sure it will become the Next Big Thing as soon as the fruit company releases it, but I am also sure that they will make their own proprietary system.
