iTunes opening when you attached your device is handy to start with but soon becomes an annoyance. iTunes pops up, invariably there will be a dialogue box of some sort when all you wan to do is give your device a quick charge.
iTunes has changed how you stop it launching when a device is plugged in, before you would open iTunes, select your device, go to the Summary tab and unselect Open iTunes when this iPhone is connected. With iTunes 18.104.22.168 that option has moved.
How to stop iTunes running when plugging in your device.
- Open iTunes (or just plug your device in).
- Goto preferences
- Click devices
- Un tick Prevent iPods, iPhones and iPads from synching automatically.

and you’re done. The only thing to bear in mind is that now you’ll need to run iTunes manually if you keep your backups on your system.
