iPhone 6 is published 2 years ago, Because of the Apple product’s good performance, many people who brought iPhone 6 one or two years ago still using iPhone 6 now. My girlfriend is one member of the iPhone 6 army. Every iPhone 6 owner knows that the biggest enemy of iPhone 6’s performance is its fast power consumption. So we decide to tell you how to solve this problem.
We had just received a iPhone 6 from a customer, the failure is described that the iPhone can be turned on normally, but it consumes electricity very fast. Its power drains out after one night without use. By the way, the owner often plays iPhone while charging before. So what’s the problem?
First we need to know whether it has electricity leakage while charging or while pressing the iPhone power switch. Because of our customer always playing iPhone while charging, we need to check iPhone charge management IC and iPhone USB control IC and diagnose the place problem happened.
Disassemble iPhone with particular screwdriver and prying tools. Take apart the iPhone motherboard, and check it under 7-45X Trinocular Stereo Zoom Microscope. We final found that there is no noteworthy problem.
Connect iPhone motherboard with DPS DC power supply, supply power to the iPhone motherboard. We found no leakage phenomenon. However, when we press iPhone power button, the current jumps up to 200mA, it's abnormal.
