iPhone connects and disconnects from Mac

Hello,

When I plug in my iPhone to my Macbook pro, it repetitively connects and disconnects. Therefore I cannot charge my phone through my computer anymore.

I own this iPhone since decembre 2018, and this issue only appeared this week. However when I plug in my iPhone to a wall outlet, it charges perfectly. I also noticed that there is a lag time before my phone starts charging when connected to my Macbook (before disconnecting right away, and then reconnecting etc).

I tried to connect my iPhone to both USB ports of my Macbook, with many different Apple lightning cables and also my Anker cable (MFI certified), but the issue substains. I plugged in my mother's iPhone 6 to my Macbook and it charged perfectly. I plugged in my iPhone to my brother's former Macbook pro (15" from 2008) and my iPhone could charge normally.

Here everything I tried to resolve this issue (which failed by the way) :

- I shut down and turned on my computer and my phone.

- I reseted location and privacy of my phone (Devices rapidly disconnect/reconnect - Macbook Air Mid 2013).

- I also restored my phone.

Could anyone tell me a solution?

I specify that I have a 256Go iPhone X under IOS 11.2.5 and a 13" retina Macbook pro (mid 2014) under High Sierra 10.13.3.

But I do think I solved my problem, by something similar.

On the hunch that the computer was trying to set up a network connection via the phone while the phone was trying to do something else, I went into the network settings and found that in the list of services I had an entry for "Thunderbolt Bridge." I thought it was off, because it was listed as Inactive and the configuration I could see said "Configure IPv4: Off". But to make sure it was really completely disabled I pushed the "Advanced" button to change the configuration details (after clicking the lock icon and authenticating, of course). I changed "Configure IPv6" from "Automatically" to "Manually" and saved that.

After that, connecting my phone to the laptop finally worked. I was just now able to get some pictures off my phone onto the laptop.
