TechInsights updated their (8 plus teardown) info to show 338S00309 and 338S00306 as Apple/Dialog and commented that there is one more PMIC from Dialog compared to the 7. The 338S00306 chip isn’t even mentioned in this article. It looks like the chip has tape (or some other covering) over the top of it in the photo on this article so the markings can’t be identified. It would be the chip just below the NXP80V18 secure NFC module. Also, I think one of the orange circled PMIC chips in this article is actually a 338S00295 Audio Amp instead.
Are there any unidentified chips that are 3mm x 3mm ?
