iTunes on my laptop doesn't recognise my iPhone 6. My laptop does, it's just the iTunes that doesn't.

If you don't see your connected device in iTunes for Mac - Apple Support - https://support.apple.com/HT203979

Device not listed immediately after upgrade - https://discussions.apple.com/thread/6573744 - try restarting

You do not say anything at all about your computer. I don't even know if it is a Mac or a PC. This may apply to you:

iOS9 on a mobile device requires iTunes 12.3 or higher which in turn requires a computer running OSX 10.8.5 or higher. System Update only checks for updates for the current system version you are running but that itself may be out of date. It may or may not be possible to upgrade your computer to the required system. Find your computer model on the http://www.everymac.com web site and near the bottom of the system specification section it will say what OS versions it is capable of running. If you cannot run a newer system you will not be able to sync this phone to your present computer. If it can run 10.8.5 or higher you can either buy a download code for OSX 10.8 Mountain Lion from Apple online, or you can try installing the free El Capitan OSX 10.11. El Capitan may run slower on older machines and require additional RAM purchase. Doing a big jump in system versions is also more likely to affect old software.

Snow leopard to el capitan, will it cause my macbook to be slow? - https://discussions.apple.com/thread/7412959

Mountain Lion 10.8 purchase link U.S.A. - http://www.apple.com/shop/product/D6377Z/A/os-x-mountain-lion

Current OSX general upgrade information, including system requirements - http://www.apple.com/osx/how-to-upgrade/

If you have any PPC generation software that has been running under OSX 10.6 it will not be supported under any later system versions.

You'll need iTunes version 12.3.x.

Hi.

I also had the same problem as you and I couldn't get iTunes to recognise my iPhone 5S. However, what I did and worked for me was this (I have a PC) :

1. Go to Control Panel,

2. Click on "View devices and printers" you will find this in the Hardware and Sound section.

3. Your device would PROBABLY be in the "Unspecified" section.

4. Right click on the device called "Apple iPhone" or "Apple Device".

5. Click on "Remove Device".

6. Unplug your device.

7. Plug it back in.

This should work, as it worked for me.

P.S. I am using Windows 10 PC.

I don't know if we should be linking to other sites on here or not, but the instructions found at the following website worked perfectly for me. I know nothing about the site and have no affiliation with it, but it worked.
