Assumptions: Using the iPhone 6 Plus (NOT the 6); and Using iOS 8.x. My Plus is laggy all over. For example, opening Apps/going to homescreen/unlocking the phone the animations are choppy as it draws up the UI like there's a pause and then a laggy flash of UI draw. I also notice black screens sometimes when opening Apps (e.g., Facebook). This experience seems exactly like the iPad 3 lag. Looking to see if others are experiencing these things. Please vote in the poll. And then there's the potential lack of RAM: getting Safari Webpages reloading after leaving the App and entering back in... sometimes it happens.
