From colleague to send the iPhone 6 machine, before opening, peers, just let me know, battery soon, new to change the battery, the fault is still

Peers said, I can trust, so the whole machine test all function is normal, down the mainboard test, there is no obvious short circuit,

Adjustable power supply test, turn off current is normal, and then into the system test, current slants big, appropriate and standby test current is larger

More to the development of such failures are generally not bad USB pipe, then replace the new USB pipe

Change after the test, the current obviously returned to normal, capacity test, the battery power consumption slowed significantly, machine repair success
