Like most Apple announcements, there was mention of a faster chip, a more detailed camera, and a tougher screen.
But the most significant change was the announcement that the new iPhone 12 wouldn't come with AirPods or a charger, and less packaging as a result - 50% less, to be exact.
Apple's marketing department says:
93% of the packaging is fibre-based, due to our work to use less plastic in packaging
100% of the wood fibre comes from recycled and responsible sources
72% recycled content in fibre packaging
