You're comparing less than ten years. Here's what I see, 2009-2019:

iPhone 3g: 4.5 Wh / 0.0335 kg = 134 Wh/kg

iPhone 11: 11.91 Wh / 0.047 kg = 253 Wh/kg

For a 1.9X improvement.

Agreed, consumers aren't seeing 3X. But they should be seeing better than 20%.

Not sure where you found the data for 3g and whether they follow the same methodology as apple (the report shows up to iphone 4 which was introduced in 2010), but even if I assume that they are correct, what you are proposing is even more far-fetched.

That in 2010 something dramatic happened in the battery technology world and they doubled in density overnight. Hint: No they did not.
