Reduce Motion and Transparency
iPads and iPhones feature cool motion animations – changing how apps fade in and swoop out – and the transparency of various app elements.
While these things look nice, they aren’t necessary and they could be slowing down your iPad when it’s busy trying to do other more important tasks.
In the General section of Settings, look for the Accessibility section, where you can find the option to Reduce Motion, which will minimize these transitions and can lead to a faster experience.
