I also feel it. After you unlock your phone , it will lag for 1-2 Sec before your app can work
I am using ip6s. iOS ver 9.0.1
I also encounter this but not everytime.
the solution is to reduce motion - ON.
what ios version are you running and did you restore from backup?
seems widespread via http://forums.macrumors.com/threads...ag-serious-issue.1921141/page-7#post-21962520
