With wireless charging being inefficient and adding heating concerns, along with the fact that several years ago Apple announced and later abandoned its AirPower charging mat, and the fact that Apple has been marketing being environmentally friendly, I’m not sure if the entire iPhone range would become completely portless anytime soon. Currently the portless devices from Apple are the Apple Watch and AirPods families — both small enough to discount inefficiencies and the environmental impact. Based on this, the first portless iPhone would be the smallest one, which would be somehow segmented so that customers still buy the more expensive models with the USB-C port.

My questions is do we have any way to make high power wireless charging, say 40 to 50W that is more efficient and lower heat. I believe we are currently reaching close to 80%. The idea of Wireless charging is great, but the reality is that it doesn't work well in hot environment, it is comparatively slow and expensive.

The magnet in MagSafe really does wonders to increasing efficiency and decreasing heat escape. It really should just be the default, non-MagSafe wireless chargers are dangerous. I haven’t inserted a cable into my iPhone for around 6 or so months now. The port is there, but it doesn’t seem to be doing much.

  I regularly backup my iOS devices via the cable. It’s much faster than OTA sync. It’s also useful when transferring very large files.

    Ya, it’s not something I’ve done since 2008 or so. I guess I just got too used to iCloud?

I really don’t understand why people complain about the efficiency of MagSafe charging. The impact is ridiculously negligible. Turn your thermostat by half a degree, or cut your shower short by a few seconds, and you’ve probably saved more energy than wireless charging will ever waste. I don’t believe for a second that anyone complaining about wireless charging inefficiency is spending a proportionate amount of attention on efficiency in other aspects of their life. I don’t usually need fast wireless charging so I intentionally plug my wireless charging stand to a slow 5V USB charger. There is no noticeable heat on the phone after charging that way.
