No, he's right. There are dropped frames in this situation. If you drag the homescreen up and down for spotlight without letting go, smooth as butter. But as soon as you actually go into spotlight, leaving will always have small frame drops. I've restored my iPhone 6 as new numerous times because I have such bad battery life (which for the record, is still 6 hours or less >_>) and this little stutter has always been there. However it doesn't bother me AT ALL because I have been using an iPad mini 2 on iOS 8 for quite awhile now
