    I wonder if iOS 9.3 on iPhone 6s(+) has shuttering, lags or frames drops as the iPhone 6. Experiences?

    Even an iPad pro will stutter when scrolling in the Music app (for example).

    9.3 is best 9 version yet but it's no an iPhone 5/iOS 6 smoothness by any stretch.

    my 6s plus does occasionally stutter, sometimes Ive noticed that when not used for a while, ill pick it up and it is sluggish, seems to disappear after 5-10 mins.

    9.3 is the best release of ios 9 anyway, and the 6s plus is a lot better on it than previous releases, still not perfect, but nothing is i guess!

    Blame Metal if anything - I have noticed Metal really struggles with moving graphics (Emoji keyboard scrolling stutters a lot).

    OpenGL never had these issues. For all intents and purposes iOS8 and iOS9 basically looks identical, but performance in really basic areas (scrolling Settings for example) just does not perform as well - the system hasn't been radically overhauled, or some new high definition graphics put in place to cause it. The key change has been the shift from OpenGL to Metal, and we are all suffering as a result (even the newest phones have stutter, so it's not hardware).

    Yep, even new iPads like Air 2, Pro and Pro 9.7 stutter. Shameful.

    Not an S, but my iPhone 6+ has been running great since 9.3. The lag is virtually non existent now.
