iOS 12 is faster than 11. Compared to 10, very slightly faster on some operations, slightly slower on others. But you get two years of features including the ones from 11, which are iPad specific. If you use your Pro as a mac replacement, i would say update. iOS10 multitasking is horrible.I have an iPad pro 10.5 on iOS 10 that run very fast and the battery is very good!! I am wondering the same as other people..does it worth to upadte on iOS 12!??? People that have iPad pro what's you Opinion?
