Weird problem with reassembly after water damage

Hello,
after I spilled some water on the lower part of my XR. It had a minor water damage issue and some intrusion sadly. I disassembled my phone the next morning (Sunday) and left everything opened to dry out. I found some water drops under the Taptic Engine and the liquid damage sticker next to it is pretty red (others are white).
Weirdly enough it booted up fine today, like nothing happened (without Taptic, speaker and antenna). During reassembly (piece for piece & turning back on again) it stopped working just as I screwed down the little metal-rubber-bracket that pushes/fixes the connector of the Taptic Engine. But without this (just connected) it seems fine. Also all parts are working fine.
Could this be an issue of the charging port flex cable running on the backside? Thanks in advance for any tips and ideas. (Oh and needless to say, there’s nothing left not backed up and I‘ll be getting a new phone in September but this has become something I want to get done.)

Hi,

From experience I can say that it is very common for the X series to have random shut down when there is water damage in the charge port area.

There are 2 parts that are antennas and one that is the charge port. If you do not have parts to rule out which one is causing it, you could simply replace all 3. There are all fairly cheap to purchase and needs to be removed anyways if you are removing the charge port.

Note that you will need to remove the motherboard to remove the charge port.

Maybe simply start with the long metal braket that is on top of the charge port since there is no disassembly involved beside that metal bracket . It acts as an antenna I believe, and it has some circuitry on it (under it) that often causes the phone to randomly shut down when it is water damage.

You could also try to clean any mineral deposit with a brush, q-tips, and some iso 99%, but in many case replacing the part is the best way to go.

I hope this helps

I can't thank you enough for your detailed answer.

After a little bit of overthinking & reading your answer I orded a new lightning port flex and GSM antenna online (was around 15€) and since my phone was parted out completely already, I started installing today after work, again checking after some significant steps if my phone was doing OK.

As of now (~2 hours later) I'm typing this answer from my water damaged (and believed to be dead) iPhone XR.

It wasn't very difficult due to iFixit guides and videos (plus normally I work on bikes and cars and my phones until my 5s). So I can just recommend everyone to give it a try.
