Many iPhone and iPad users are complaining that all the movements in the new Apple operating system are giving them symptoms of motion sickness and vertigo. Unfortunately, you can’t turn all of the movements off, but there’s one little trick that may help.
If you look carefully, you can see the icons on the home screen actually move around on the background. To turn this feature off, touch Settings, choose the General tab, then Accessibility.
Look for the “Reduce Motion” option and turn it on by touching the switch on the right hand side. The switch should turn green.
Now, when you go back to your home screen, your icons will stay put. This will also save some battery power, too.
