>value added per unit of resources used is growing exponentially

I would love to see the amount of resources that are used to produced each iPhone, because I don't have a big issue assuming that each phone brings, say 3 or 4 percent more utility to its user than the previous model would have.

So, assuming the battery is the most dirty part of the phone, I found the battery size for all the iphone models[0] and even if we exclude the the large ones, the iPhone 11 has a 54 percent larger battery.

The phones were released in 2007 and 2019, 12 years and 3 months apart[1]. That works out to a growth of approximately 3.3%.

So my original assumption was wrong, there has been an exponential growth in materials that nearly matches GDP growth.
