Is your iPhone, iPod touch, or iPad constantly disconnecting and reconnecting when linked to your Mac or Windows computer via the Lightning or USB-C charging cable? If so, you are not alone! In this post, we offer some quick tips to get your iDevice connecting normally and consistently to your computer again!
Many of us rarely connect our iPad to our MacBook or PC. We update our iPads over the air and regularly backup our device into iCloud using wi-fi.
There are however times when you will need to connect your iPad to a computer to restore it, reset it to the factory settings or perform an iOS update via Finder (macOS Catalina+) or iTunes.
It can be frustrating when your iPad doesn’t connect to your MacBook or Windows PC.
Sometimes it just shows an error connecting to the device, and at other times, it connects and disconnects continuously.
If you are facing this issue with your iPad, the chances are that your USB cable may require an upgrade.

iPad Still Not Connecting to Your Computer?

This happened a few months ago and I went 3 hours away to apple store and they swapped out my iPhone. After restore the phone and Mac worked fine. Now it started again today and I have done all the steps posted to fix but to no avail. And FYI to everyone who says just trust the phone from the computer it is an impossible task because the iPhone is disco and reconnecting every half second. You cannot click on trust for this reason. I know I am sick of it and this a situation I need it badly. I’ve worked on this all day. I’m ready to trash apple products and go back to android. This is complete bs. If apple knows it’s a problem then have your smart overpaid engineers fix the damn problem???!
I would discourage the use of a cotton tip when cleaning the port as fibers may become lodged inside.
If you do not have a nylon brush please let your local Authorised Apple service center clear it out for you.
Better to be safe than sorry.
This problem is most of the time due to the iPad not being completely charged. It can be solved by charging the device to 100% via the charger and then connecting.
