Hi Guys.. I have an iphone 6s Water Damage. After Ultrasonic bath, i try to on it, the DCPS draw current between 0.01mA - 0.08mA or 9. All VCC main voltage are regular. I find only 9 volt on c2300 if i plugged battery and usb, only on one side. Without battery connect one side the voltage is 4 other side also 4. I try to change this capacitor but the problem is same. I already change tristar and Tigris. Anybody help me plz.
That is normal behaviour for C2300. It is part of the Tigris buck converter circuitry and when the phone is charging, you will see 9V on the IC side and ~4.2V on the coil side. You need to continue your troubleshooting by checking the output voltage rails from the PMIC and the BBPMU to see if there are any shorts.
