Using the OnePlus 5 now I can tell you that it runs really really well. My two friends with iPhone 7 Plus units seem to have stutters that I don't seem to get. I have so many programs running including paired Bluetooth headphones, speakers, Prius car radio, etc. Constant emails from two separate emails, constant scheduled feeds and reminders, two step counter apps running in the background, etc. Nothing slows this thing down.
