iOS 11.2 accelerated wireless charging speed vs wired

Matt Birchler compared the time it took to charge an iOS device using:

  • Stock wired charger
  • Apple 29W charger
  • Wireless charging (available on iPhone 8, 8 Plus, iPhone X)
  • Accelerated wireless charging (New with iOS 11.2)

Follow the link, check out the graph. To really get a sense of the difference, look how many minutes it takes each to get to a 40% charge (the second horizontal gray line).

The 29W charger took just under 30 minutes. Accelerated charging took about an hour and 40 minutes.

I don’t know how rigorous this analysis was, but wow, what a difference. We could be seeing the limitations of inductive charging, or we could see these numbers improve with each new release.

Important to note that Matt used a Samsung wireless charging pad. So it is certainly possible we’d see better numbers when Apple releases their branded pad.

But as is, what price convenience?

UPDATE: Had a lot of conversations about this post, about the value of the convenience brought by wireless charging. Add to that the fact that the latest iPhones have plenty of battery life, and the use case comes into focus. Instead of placing my phone on my desk while I type away, if I simply place it on the charging pad, I’ll get a nice little power top-off without the hassle of plugging in.

Conclusion? Wired is clearly a faster charge than wireless, but that’s just fine. Wireless does the job it was designed to do and brings great convenience to the process.
