iPhone 7 model A1778: I have a missing capacitor and I’ve been unable to find a schematic that matches the intel version of this iPhone. I wanted to find it’s capacitance and replace it but I have been having a hard to time doing that or even finding where to buy capacitors that small online. I also have an iPhone 6 and was hoping I could use a capacitor from it since its a close model. Capacitor: C5725 _RF next to IC U3601. To see it, you need to go to iPhone 7 Plus (Qualcomm) on PB.

C5725_RF is a 2.2UF 20% 4V X5R-CERM with a 0201 package size. On an iPhone 6 you’ll find plenty of similar caps, the only difference is they are designed for a max of 6.3v instead of 4v. You can use them for replacing your faulty one without a problem, just test they conform to specs.
