Step by Step Tutorial on How to Disable JavaScript on iPhone 15

Before diving into the steps, it’s important to note that disabling JavaScript might prevent some web pages from displaying correctly. However, for those who prioritize speed and security over full functionality, here’s how you can turn off JavaScript on your iPhone 15.

Step 1: Open Settings

Firstly, open the ‘Settings’ app on your iPhone.

Once you’re in Settings, you’ll find a long list of options. You’ll need to scroll down to find Safari, which is Apple’s default web browser for iOS.

Step 2: Scroll to Safari

Scroll down and tap on ‘Safari’ to access its settings.

In the Safari settings, you’ll have a variety of options to customize your browsing experience. We’re focusing on the ‘Advanced’ section, which is where the JavaScript settings are located.

Step 3: Choose Advanced

At the bottom of the Safari settings, you’ll see ‘Advanced.’ Tap on it to continue.

The Advanced section contains several technical settings that can enhance your browsing experience. Here, you’ll find the option to enable or disable JavaScript.

Step 4: Toggle JavaScript Off

Find the ‘JavaScript’ switch and toggle it off.

After you switch off JavaScript, your settings are automatically saved. There’s no need to confirm or restart your browser—it’s that simple!

Additional Information

While the process of disabling JavaScript on your iPhone 15 is straightforward, there are a few things to keep in mind. For one, not all websites are created equal. Some are designed to be fully functional without JavaScript, while others rely on it heavily. If you frequently visit a site that requires JavaScript, you might find yourself toggling the setting on and off, which can be a bit of a hassle. It’s also worth noting that while disabling JavaScript can protect against certain online threats, it’s not a foolproof security measure.

It’s always a good idea to have additional security measures in place, such as a reputable anti-virus app and being cautious about the websites you visit and the downloads you make. Lastly, remember that the option to disable JavaScript is specific to Safari. If you use a different web browser on your iPhone 15, you’ll need to check if and how you can disable JavaScript within that particular app.


  1. Open the ‘Settings’ app.
  2. Scroll down and tap on ‘Safari’.
  3. Tap on ‘Advanced’ at the bottom.
  4. Toggle the ‘JavaScript’ switch off.
