iPhone 17 Pro Max: 5 iOS 26.4 Settings You Should Change for Better Security and Battery

The iPhone 17 Pro Max includes many advanced features, but several useful settings remain unchanged by default. Adjusting a few options in iOS 26.4 can improve security, extend battery life, and make everyday interactions faster.

The following guide explains five important settings worth reviewing. Each section includes the exact location of the setting and a clear explanation of how it helps.

1. Enable Stolen Device Protection

Stolen Device Protection adds an extra security layer if a device is lost or stolen. Even if someone knows the device passcode, certain sensitive changes require Face ID authentication and an additional security delay.

Where to find it:

1. Open Settings
2. Tap Privacy & Security
3. Select Stolen Device Protection
4. Turn the feature On

This setting helps protect critical data such as Apple ID details, saved passwords, and payment information.

Warning:
When Stolen Device Protection is enabled, certain account changes may require a security delay when the device is away from familiar locations. This is normal and designed to prevent unauthorized access.

2. Turn On Adaptive Power

Battery performance can vary depending on usage patterns. Adaptive Power automatically adjusts system activity when battery consumption increases.

Where to find it:

1. Open Settings
2. Select Battery
3. Enable Adaptive Power

This feature reduces background activity and slightly adjusts performance to extend battery life during heavy use.

3. Customize the Action Button

The Action Button can be assigned to several quick functions instead of only controlling silent mode. Customizing it allows faster access to frequently used tools.

Where to find it:

1. Open Settings
2. Select Action Button
3. Choose the preferred function

Available options may include:

• Opening the camera
• Turning on the flashlight
• Starting voice recording
• Launching a shortcut

Assigning a commonly used feature can reduce the number of steps needed to perform everyday tasks.

Helpful Tip:
Setting the Action Button to open the camera allows instant access to photography without unlocking the device. This can be useful for quickly capturing moments.

4. Adjust Always-On Display Settings

The Always-On Display keeps certain information visible on the lock screen. However, showing wallpapers and notifications constantly may increase battery usage.

Where to find it:

1. Open Settings
2. Tap Display & Brightness
3. Select Always On Display

Optional adjustments include:

• Disable lock screen wallpaper
• Hide notifications
• Keep only the clock visible

These changes help maintain a cleaner lock screen while conserving battery power.

5. Set Haptic Touch Speed to Fast

Haptic Touch controls how quickly menus appear when pressing and holding on apps or elements. The default delay can feel slightly slow for some users.
