Apple’s new iOS 10 redesigned and revamped for unlocking system in all iOS device. In that you must press home button once for unlock screen and other good feature is Raise to wake iPhone screen. But this only available in selected Motion processor iOS devices. In that you unfeel and disappointed with iDevice (iPhone/ iPad) Home button slow to respond. Here is the quite configuration mostly works for all and fixed the real problem automatically itself.
I recommend for this situation by using home button given assistive touch. Enable Assistive touch and use it, not physical home button. So many hard strokes on home button obviously creates a physical problem.
Customize or Manage Home button speed for Specific device is great option given in Settings app. Wrong customization
1: Go to the Settings app on iPhone/ iPad.
2: Next, Tap on General Option under the Setting.
3: Then Tap on Accessibility.
4: Scroll Down beneath of the Screen, Tap on Home Button.
5: Next you will find Three Click Speed Option.
Default Option recommended by apple, you should go with it for maximum speed and response.
Other two Options are Slow and Slowest. Make sure and uncheck if you set it.
