Part 2. How to Fix iPhone 6 Plus Lagging and Freezing?

To help you fix this problem, I will recommend the top six tips which are commonly used by you.

Fix 1. Remove Unnecessary Apps/ Data

The most effective way to increase your iPhone storage is to remove some unnecessary apps or data that may take up space on your Phone. You can try to search the documents and delete some photos, audio or video files, emails, or messages on your phone.

Fix 2. Quit All Apps Running in the Background

Similar to what happens on computers when several programs are running at the same time, your iPhone can also slow down when several apps are running in the background. The application memory on your iPhone is loaded each time you open an app. Your iPhones application memory fills up as more apps are opened. Regardless of whether you're no longer using the app, it remains active in the background and is loaded into your phone's memory until you close it. Since your iPhone has lots of apps open at once, you should expect it to eventually slow down.

To solve it, you can set your iPhone to run certain apps even if they aren't open, here are steps to follow: Open Settings → General → Background App Refresh. This menu shows you which apps are currently allowed to keep running even when they aren't opened on your iPhone 6s Plus.

You can simply turn off Background App Refresh for an app if you think you don't need it running in the background. Choose only a few essential apps to keep running as much as possible. After that, check if your iPhone 6 plus lagging and freezing problem persists.

Fix 3. Clear Safari Cookies and History

You can also clear Safari cookies and history which also takes up many storage spaces on your phone. Go to Settings→ Find Safari → Tap Clear History and Website Data. Then select the Clear History and Data in the popup window.
