Part 2: More Potential Solutions for iPhone 6 Speedup.

You may follow the tips below to speed up iOS 10/9 on any iPhone/iPad/iPod touch.

  • Turn On Reduce Motion
  • It can help to speed up any iOS 10 device by toggling off the snazzy zipping and zooming motion effects. Open the Settings app>Go to "General" and to “Accessibility”>“Reduce Motion” and turn this ON. Note that Reduce Motion will also turn off most of the fancy new Message effects.

  • Cut Visual Effects with Reduce Transparency
  • Another way to cut down on visual effects is with Reduce Transparency, which can speed up interactions with Control Center, the Lock Screen, and Notifications by reducing the translucent interface elements. Open Settings>General>Accessibility>Increase Contrast and toggle ON the “Reduce Transparency” setting.

  • Disable Background App Refresh
  • Background App Refresh uses system resources to maintain apps in the background, disabling this feature reduces activity and thus can improve performance on a sluggish device. Go to Settings>General>Background App Refresh, and turn the feature off completely. Toggling off Background App Refresh also boosts battery life on many devices, so that’s a nice added bonus.

  • Restore As New
  • This is the nuclear option. Instead of updating in place, or restoring from an age-old backup, you start fresh and clean. You can re-sync accounts and content, including apps, from iCloud and iTunes, Google, Dropbox, and other online services, but you'll otherwise be starting over from scratch.

Now, you could fix the iPhone 6 running slow issue successfully. If you still want to improve iPhone system performance, you can try removing old apps, reducing the background apps and transfer bulky files off your device.
