My iPhone 6s Not Turning On Or Charging
I Had My iPhone In The Car And i Had It Charging Via The USB Port Provided In Cars And Just Out Of A Sudden It Went Blank And Won't Turn On Or Charge And I Carry It To Fix And A Guy Said I Need A Power IC but I'm Kinda Confused Cause There Are Two A PMIC( Power Management IC ) & A Power IC (U4500/U2 CHIP) I Don't Know What To Buy Or Do.
Bu iyi bir soru mu?

Language is important. In this scenario, the likely problem is at the brain-like USB PERMISSION chip. It is called TRISTAR on the schematic, and written on the chip is A1610, it is made by NXP. This chip has been going bad from using non-Apple chargers since the iPhone 5---and back in those days it was referred to as "U2" because tristar happened to be in the U2 board position in the iPhone 5.
Tristar is STILL commonly referred to as "U2 ic" which is not appropriate since it is not in the U2 position. It is called "Charging ic" even though it does NOT charge the phone--it negotiates the usb interface.
Completely unrelated is the traditional PMIC, power management chip which creates the many power rails in the phone from the battery. In the iPhone 6, the PMIC is often blamed for many problems, but it does not fail outside of water damage.
