I was suspired when Apple announced mmWave in iPhone 12 and OLED. Both of those were expensive. Knowing Qualcomm would increase the cost. I wrote about the cost concern in 2019 and recently 2020 [1]
But then Apple had all the OLED supply agreement from Samsung to Fill, left over from last few years. And the pandemic made lots of uncertainty if they will even shift through any decent unit volume. I mean most were expecting a **** storm, turns out US economy is much more resilient.
Next year is going to be even more interesting. Are we going to have Worldwide roll out of mmWave iPhone ? ( It doesn't make any sense, but apple may have mmWave antenna for other usage )
Are we moving to Qualcomm X60? Which will be the first time Apple has leading Edge node in both SoC and the Modem ( again it doesn't make sense due to capacity and cost concern )
Are we moving to LPDDR5? We seems to be the case for M1X.
Apart from the Camera lens, it would seems to be Apple has filled all the low hanging fruit with iPhone 12. The only thing left is LTPO 120Hz OLED. And possibly a Touch ID, which would be another cost as well.
Not entirely sure what is left for iPhone to improve, other than getting rid of the notch over a long period of iteration. And nothing in the current BOM list will get any cheaper in the short term either. Everything is and will be more expensive.
