iPad Pro 9.7 inch lag and stutter during game

My Pro is also lagging.

Really great tips, but laughable they should even need to be considered on a new iPad!

Similar tips turned out to be very useful to me when my super old iPad 2 was lagging on the latest iOS 9......

Could be a lot of thngs.

First, could be a variable speed in your Internet/Wifi connection slowing you down, if there is a lot of Internet traffic during different intervals of the day.

You could try turning off iDevice resource hogging activities.

Make sure you don't have a lot of apps running in the background in the iOS App Switcher, if you do, slide each app up to quit them.

Turn off Background App Refresh to stop apps from updating in the background.

Turn on Reduced motion to minimise all of the iOS motion graphics eye candy. This, alone, will improve iOS performance.

If you use any Bluetooth devices, but aren't always using them, make sure to turn off Bluetooth for the time being.

Set your iOS Mail app to fetch mail at longer intervals OR set to manual fetch to only get mail when you launch the Mail app or when you just, manually checking mail.

If you wish, limit what apps get Notifications and use Location Services to cut down on background activities.

All of these things will improve performance and save battery life, too!

Good Luck!
