How to Turn off iOS 9 Update Notification

Click on the Setting icon.
Then click on General.
click on Storage & iCloud usage. It might just say Storage on your device.
When the next page pops up you will see at the top the word Storage. Under it you will see Manage Storage. Click on it and wait till the list is fully populated. Depending on how many apps you have this can take a couple of seconds to about half a minute.
Look through this list till you see the new iOS update. Delete it.
Then your pop up notice should go away. Don't worry about loosing the update. You can always get it later in the future. If in the future you get the pop up again, then that means Apple has again downloaded it to your phone or iPad without your permission. Simply do the above all over again to delete it and get rid of the new pop up. This is the only way to get rid of the pop up without installing it.

Thanks! Just followed your instructions and hopefully this stops the annoying pop up. Got any suggestions for the same problem with Mac updates? Appreciate your help!

Thank you! That nagging was getting really annoying. I'd unlock my phone to do something really quickly, and I'd have to say "no" twice to get past the "reminder," and there wasn't any option for "Don't remind me again – I'm perfectly capable of updating when I want to." Apple's getting really pushy with updates lately, and I don't appreciate it.

thank you sooooooo much this was bugging me to death!!
