iPhone 6 Sensor Failure and Fast Power Consumption how to Repair.
vip pro shop team have sloved the most common questions about how to fix iPhone 6 Sensor Failure and Fast Power Consumption Repair. Depending on the device, mobile phone repairs can be a tedious process. Troubleshooting is a vital part of both diagnosing a broken part, and discovering what step was missed after repair. we are here to make your life easier.
issues:
Received a customer's iPhone 6, according to his description, the fault is that the sensor can't be used, and the iPhone 6 battery power consumes very fast. How to fix the faults? First we need to connect DC power supply to have a test.
Repair process:
Disassemble to connect power supply, the value is normal with standby mode, when turn on the iPhone 6, it's found that the current jumps from 300mA, the normal current should be from 80mA. As shown in picture 11-7-1.
Customers said that the phone is not black screen, the flex cable was replaced before but the failure is still existing, it seems that the fault is from sensor. Take out the universal multimeter to measure iPhone 6 motherboard. As shown in picture 11-7-2.
When testing 3V power supply on sensor, plate is short circuited to the ground, the power supply goes out of the PMU to the J1111 interface, with a series of capacitors in the middle. The capacitance is distributed in three places: near J1111, the upper left corner of the iPhone audio, and the power supply. These three places are all smoked with rosin flux to check.
The capacitor rosin on the top of the PMU chip is melt, so we pry it out. As shown in picture 11-7-3.
The resistance was restored to normal, and the electric current jumped to normal. Install the iPhone 6 to test, the sensor is also normal now. As shown in picture 11-7-4.
