Turn off Automatic App Updates and Downloads
Your phone can be sneaky and cause your phone to slow down due to automatic app updates and downloads that you forget about. It is best to update your apps manually and turn off all automatic updates. Automatic downloads also can cause a bit of a slow down because it enables downloaded apps on another one of your Apple devices to automatically install on your iPhone.
Here’s how to change this in your settings:
- Open Settings.
- Tap App Store.
- Toggle off Apps, App Updates, and Automatic Downloads.
