With the iPhone packed full of advanced features, many default settings that seem harmless can actually affect your phone’s performance, battery life, privacy, and overall usability. Plenty of iPhone users overlook these important options—especially the ones quietly added in recent iOS updates.

This article walks you through the 10 most important iPhone settings you should review and adjust right away to unlock the full power of your device.

1. Turn Off Precise Location for Apps That Don’t Need It

When you install a new app, it often asks for access to your location. While this is necessary for apps like food delivery or maps, most entertainment or social media apps don’t need to know exactly where you are.

Allowing too many apps to track your precise location can drain your battery and compromise your privacy.

How to adjust:
Go to Settings → select the app → Location → turn off Precise Location.
When turned off, the app will only know your approximate location, not your exact coordinates.

2. Use the Back Tap Feature to Add Shortcuts

Available from iOS 14 onward, Back Tap is a hidden gem that lets you assign quick actions like taking a screenshot or turning on the flashlight by tapping the back of your iPhone two or three times.

How to activate:
Go to Settings → Accessibility → Touch → Back Tap → choose Double Tap or Triple Tap → assign the desired action.

It’s a great way to speed up tasks without unlocking the screen or hunting through apps.

3. Enable Live Voicemail Transcriptions

One standout feature in iOS 17 is Live Voicemail, which lets you read voicemails in real time as they’re being recorded. This allows you to decide if the call is important enough to answer immediately.

How to turn it on:
Go to Settings → Phone → Live Voicemail → toggle it on.

It’s a huge time-saver and can help you catch urgent calls without wasting time listening to messages later.

4. Restore Full-Screen Incoming Call Alerts

If you find the small incoming call banner annoying, you can switch it back to full-screen mode—just like it used to be.

How to change it:
Go to Settings → Phone → Incoming Calls → select Full Screen.

This helps ensure you don’t miss calls, especially while multitasking in other apps.

5. Turn Off 5G When It’s Not Needed

5G is fast but consumes more battery than 4G. If you're often in areas with poor 5G coverage or simply don’t need the speed, it’s better to switch to LTE to save battery.

How to disable it:
Go to Settings → Cellular → Cellular Data Options → Voice & Data → select LTE.

You can always turn 5G back on when needed. To fine-tune further, head into Data Mode and choose how aggressively your iPhone uses data.

6. Unlock iPhone While Wearing a Face Mask

Starting from iOS 15.4, you can unlock your iPhone using Face ID even when wearing a mask—a super handy feature in public settings.

How to enable:
Go to Settings → Face ID & Passcode → turn on Face ID with a Mask.

Unlike earlier versions, you no longer need an Apple Watch to use this feature.

7. Use Focus Mode to Filter Notifications by Situation

Focus Mode is a major upgrade from Do Not Disturb. It lets you create multiple customized notification modes for different activities—like work, sleep, or reading.

How to set it up:
Go to Settings → Focus → choose or create a Focus mode → customize which apps and people are allowed to notify you.

You can also automate Focus Mode based on time, location, or when you open specific apps.

8. Increase or Decrease Text Size for Better Readability

If text on your iPhone feels too small or too large, you can easily adjust it for better comfort.

How to adjust text size:
Go to Settings → Display & Brightness → Text Size → drag the slider to choose your preferred font size.

Turn on Bold Text for even better visibility and contrast.

9. Take Control of App Permissions

Many apps ask to access your photos, microphone, camera, or location—but you don’t have to say yes to everything. Apple makes it easy to review and change these permissions later.

How to manage:
Go to Settings → Privacy & Security → review and adjust categories like Camera, Microphone, Photos, or Location Services.

Only grant access where truly needed to protect your personal data.

10. Customize the Control Center for Quick Access

The Control Center gives you instant access to things like flashlight, music, Wi-Fi, and Airplane Mode. But you can also personalize it to include shortcuts you use most.

How to customize:
Go to Settings → Control Center → tap + or - to add or remove options → drag to rearrange.

You can add shortcuts for Low Power Mode, Screen Recording, QR Scanner, or anything else you use often.

Make Your iPhone Work Smarter for You

One of the reasons users love the iPhone is because of how customizable and user-friendly it can be. But many powerful features remain hidden if you don’t explore the settings regularly.

We hope these 10 important settings help you unlock better performance, save battery, boost privacy, and enjoy a smoother user experience. Apple continues to add helpful tweaks in each iOS update—so don’t forget to review your settings every now and then.
