Lightning Port Replacement Problems - Taptic, Service, Battery

UPDATED

Hi all! I’ve seen some questions asking for solutions to similar problems but not 100% like mine.

I replaced the charge port in an iPhone 7 and after the repair I am having a number of issues.

  1. Taptic Not Working - no vibration response to home button presses or silent switch flicks.
  2. Service constantly “Searching” - no IMEI listed in settings either
  3. Battery icon reads 1% and not charging while connected. Stuck a new battery in that I know has charge and it’s still reading at 1% and no lightning symbol to show charging status.

I know the port works to an extent because the phone turns on when I plug it in but I’m experiencing all of the above issues. Anyone have the same experience and know a solution? I’m ordering a new premium charge port and trying that out but I wanted to see if anyone had any other ideas.

Answer this question I have this problem too

Is this a good question?

A few thing to diagnose for the following:

  1. Taptic Not Working
  2. Are you referring to the vibration feedback that you get when pressing the home button, flicking the vibrate / silent switch?
  3. Service constantly “Searching”.
  4. Check if IMEI is displayed in dialer by typing *#06#. Also check if IMEI and modem baseband is displayed in settings > general > about phone. Another thing to check is Sim detection to make sure it isn't permanently stuck on searching.
  5. Battery icon reads 1% and not charging while connected.
  6. For this one check if the connector for the battery cable is seated in fully. Other things to check would be the components around the connectors on the board for any pry damage. It could be that some components on the board may have gotten prayed off or damaged.

As for Taptic. Was not responding to home button, did not actually check the silent switch.

No IMEI issue means the phone has a major board-level fault. If you want to get that fixed you'll need to take it to someone that does board-repairs on iPhones.

Did you ever resolve this issue? I’m having the same problems as mentioned above after changing my lighting port.

There is a rampant defect on the 7 and 7 plus phones where one or more pads which provide connection for the baseband chip become loose which causes the no IMEI / stuck on searching fault.

Sadly even taking the logic board out of the phone or any tension on the board can cause this.

Thanks for your reply Ben. I take it it’s fixable if I take to someone who can do board repairs? Are the other two faults I’m experiencing (1% battery & no vibration) related or are they separate faults? Many thanks, Matt.
