How to repair iPhone 6 weak signal problem


We received an iPhone 6. The problem is that the iPhone 6 signal is weak, users can't use it to make calls, or browse the web. Even if he goes to a place where the signal is good, the signal is weak. We need to repair it.





After received the iPhone 6, observe the iPhone appearance, there is no obvious physical damage.

Use phone opening tools to disassemble the iPhone 6, connect iPhone logic board to the DPS DC power supply to measure its current, the current tested is normal.

Press the iPhone power button to turn on iPhone, get into IOS to check iPhone signal. After measurement, the signal is abnormal, it's very weak.

According to the previously repair experience, there is an inductance L4608 powered by B+ to the iPhone antenna switch, we can open WUXINJI Dongle to check iPhone schematic diagram to find it.



After find out the problem, we need to short connect L4608. Put iPhone logic board under the Stereo Zoom Microscope, use QUICK 861DW hot air rework station to solder a jumper wire on L4608.



Install the iPhone and test it, the iPhone signal is back to normal，now the iPhone signal is full and strong.
