And they're all thicker than the iPhone.
Who cares? Phones should be a little thicker. The case adds thickness anyway, so a mm or two isn't a big deal.
I did just fine bringing my Anker Powerwave with me on vacation last month. My car mount is a wireless charger. And since I have an iPhone, my battery generally lasts all day anyway, unlike an android phone.
You're nuts. Most people don't bring their wireless chargers with them everywhere. My Galaxy S7 has notoriously bad battery life, but newer Android phones like the S9+ and Note 9 easily beat the iPhone on battery life. The reality is that any high-end smartphone today is going to have to charge during the day during periods of heavy use (i.e. traveling). The only smartphones I can think of that might stand a chance of surviving a day of travel are something like the Moto E5 Plus, which has a 5000mah battery on a 720p screen.
My wired charger is an Anker 30w USB-PD charger. Which has a USB-C port on the block which brings me to...
That's cool. What's your point? You're getting 18W out of that thing, TOPS.
Lightning is smaller. Here's a pretty drawing.
Not inside the phone. That was already established previously in the thread, and again in the post after yours. Other than it not being a standard, Lightning is the technically superior connector for a mobile device, and most likely the most durable. USB-C is pretty good too, and is MUCH more durable than Micro-USB, which was just a general poor quality PITA.
I honestly don't see a big problem with Apple sticking with Lightning and Android devices (hopefully) all converging on USB-C. Some are still shipping with Micro-USB, which is lousy, but all the mid-range and high-end stuff is on USB-C now. As it is right now, I have 3 sets of charging cables everywhere, and they're not going anywhere.
