Change a New Battery

Apple admits that they release updates that cause the iOS devices with older batteries to slow down and reduce their performances. According to Apple, they do this to prevent unexpected shutdowns of iOS devices that have older/worn out batteries. A relatively older battery cannot handle the processing demands as they do when they are new. The problem of slowdown is directly associated with the older/flagging battery.

So, if you want your iPhone 6 to run faster as it should with the new iOS 11/12 update, it is recommended that you replace your old battery with a new one.

Disable iOS Background App Refresh

Apart from updating when you use your iPhone apps, these apps also refresh their content in the background when you are not using them. Some of the common apps that do this include Twitter, Facebook, etc. They update their feed automatically in the background without asking your permission. This background refresh process takes up CPU resources and may cause the iOS 11/12 slow down iPhone 6 issue.

Follow these instructions to disable Background App Refresh:

  • Open Settings app on your iPhone.
  • Navigate to General > Background App Refresh.
  • Now use the toggle to switch this feature off.
  • Alternatively, you can also disable Background App Refresh feature for individual apps.
