Before we dive into the steps, let’s clarify what we’re trying to achieve here. Disabling JavaScript can help improve your browsing experience by speeding up webpage loading times and reducing data consumption. However, keep in mind that some websites may not function properly without JavaScript.

Step 1: Open the Settings App

Open the Settings app on your iPhone 15 to begin the process.
The Settings app is your gateway to most of the customizable features on your iPhone. Its icon usually looks like a gear or set of gears.

Step 2: Scroll Down and Tap on Safari

Within the Settings, navigate until you find Safari and tap on it to access its settings.
Safari is the default web browser on all iPhones, and its settings are where you can make adjustments to your browsing experience.

Step 3: Scroll to the “Advanced” Section

Once in the Safari settings, scroll down to the bottom to locate the “Advanced” section.
This section contains settings that are a bit more technical, and typically not altered by the average user.

Step 4: Toggle Off JavaScript

In the Advanced section, you’ll find an option labelled JavaScript. Simply toggle the switch off to disable it.
When you toggle off JavaScript, your iPhone will stop executing JavaScript code on webpages, which could make for a faster and more streamlined browsing experience.

Once you’ve disabled JavaScript on your iPhone 15, you’ll notice that websites may load faster, but some interactive elements may not work. If you find that a site isn’t behaving as expected, you can always go back and re-enable JavaScript using the same steps.
