Hi, My customers give me iphone 7 which was in water. I cleaned it with ultrasonic cleaner and change display. When i turn on phone, normaly show apple logo and get to home screen and when i see home screen few seconds later screen turn off but phone normaly work. I think its capacitor(from image). My question is if it was that capacitor, is same capacitor have iphone 5,5s or 6? Because i cant get that capacitor for iphone 7. Capacitor: C3725 2.2 UF 20% 35V X5R 0402
These are very easy to source and very inexpensive, check Digikey or Mouser.
same cap as 6s c4041 or c4043
