How does the source not make it clear? The first two bullets from your source.

“Apple generated $390.8 billion revenue in 2024, 51% came from iPhone sales

Apple Services is the second largest division, responsible for 24% of revenue in 2024”

[AlecSchueler]

Do either of those facts point to increases in iPhone sales?

The second source’s first paragraph says “with total sales expected to surpass previous records” for 2023, at least.

Sales are accounted for in $ terms, not units sold. It's the same thing with Hollywood. You might think movies are more popular than ever thanks to record breaking sales (pre-COVID at least). In reality, we reached peak movie, in terms of tickets sold, in 2002! [1]

Back to iPhones, this [2] page shows their stats by units sold (about half way down). iPhone is essentially treading water if those data are correct (with a peak in 2015 overcome twice since, but by ~1% each time), but I strongly suspect that that's showing units shipped and not units sold, as iPhone sales declining has been universally reported.

Ask yourself the question of what it means when a company makes more dollars from a product while not increasing the number of units sold. It's completely obvious if you think about it for a moment.
