iOS 18.6 Update: 5 iPhone Settings You Must Change Now to Boost Performance and Privacy

Apple has officially rolled out iOS 18.6, and while the update primarily focuses on bug fixes and security patches, tech experts say this is also the perfect moment to make a few game-changing tweaks to your iPhone settings. These changes can make your device feel faster, more secure, and more personalized—almost like getting a brand-new phone without spending a penny.

According to technology analysts at CNET, many of the best features in iOS 18.6 are hidden behind customization options, meaning you may not notice them immediately after updating. But with the right adjustments, you can unlock the full potential of Apple’s latest software ahead of the much-anticipated iOS 26 launch next month.

How to Maximize iOS 18.6 Features on Your iPhone

The main keyword here is iOS 18.6, and the update introduces subtle but powerful customization options that improve both usability and security. Below are the five essential changes recommended by experts.

1. Customize Lock Screen Buttons

Previously, the lock screen’s bottom corners were locked to the torch and camera shortcuts. With iOS 18.6, you can replace these with other tools such as Shazam for music recognition, Dark Mode, alarms, Airplane Mode, Wallet access, or even Tap to Cash.
Simply press and hold your lock screen, tap Customise, and choose the functions that best suit your lifestyle.

2. Prioritize Important Notifications

Tired of being flooded with scam texts and spam emails? iOS 18.6 lets Apple Intelligence decide which notifications matter most. You can enable this in Settings > Notifications > Prioritize Notifications. Messages from your contacts will take precedence over unknown senders, and you can tailor this per app for maximum relevance.

3. Redesign Your Home Screen Layout

For the first time, app icons aren’t restricted to a top-left-to-bottom-right grid. Now you can space them out for a cleaner look, tint them to match a theme, and even adjust size variations for a unique feel. Activate “jiggle mode” by holding the home screen, then drag apps freely. For uniform color themes, choose the Tinted style in Customise and adjust hue and brightness to taste.

4. Personalize the Control Centre

Swipe down from the top-right (or up on iPhone SE) to open Control Centre. Press and hold or tap the + to enter edit mode, where you can rearrange toggles, resize them for more information, and even create multi-page control layouts.

5. Lock or Hide Sensitive Apps

If you use banking apps, note-taking apps, or any tool with private data, iOS 18.6 lets you secure them directly. Hold the app icon, choose Require Face ID or Require Touch ID, and confirm. This feature adds an extra layer of privacy even if someone gets hold of your phone.

Why These Changes Matter for iOS Users

Beyond aesthetics, these updates represent a meaningful upgrade in security, customization, and usability. By prioritizing alerts, reorganizing app layouts, and locking sensitive apps, users can enjoy faster navigation, reduced clutter, and stronger protection against unauthorized access. With iOS 26 expected to bring even more AI-driven features, making these adjustments now ensures your phone is ready for the future.

Mobile technology specialists say that updates like iOS 18.6 are often underestimated because they’re marketed as “minor.” However, the combination of performance tuning, visual flexibility, and privacy controls can significantly improve day-to-day device experience. As noted by CNET’s review, “With just a few changes, you can improve your iPhone experience and be ready for the big update next month.”

iOS 18.6 is more than just a routine update—it’s an opportunity to rethink how your iPhone works for you. By making these five adjustments, you’ll maximize performance, security, and personalization, keeping your device future-ready.
