Is Your iPhone Good Enough to Be a 3D Scanner?

For creating 3D printer files, your options include smartphone apps or expensive standalone scanners.

Most 3D scanners are handheld devices that scan small to medium-sized objects with a high degree of accuracy. The resulting files are used for 3D modeling or 3D printing and they can produce fantastic results — if you’re patient and willing to learn how to use them. 

These scanners, like the popular Revopoint Pop 2, can cost $700 and have a steep learning curve. Alternatively, if you own an iPhone 12 Pro or higher you can almost recreate what a fancy 3D scanner does. It isn’t quite as accurate, especially for 3D printing, but if you spend some time tweaking, the output can be just about as good.

Creating 3D prints from files uploaded to communities like Thingiverse or Printables is fine, but once you can scan and recreate real-world objects, there’s no limit to what you can create. For example, you could replicate a collectible figure or scan a broken mechanical part to recreate it.

Using a 3D scanner

Pros:

  • Can capture detail down to 0.1mm
  • Dimensional accuracy is excellent
  • Very little clean-up when you succeed

Cons:

  • Often costs more than a 3D printer
  • Software is often very hard to use
  • Creating a usable model is painfully difficult

3D scanners use reflected light — sometimes in the form of lasers — to map the surface of an object. The scanner uses two cameras to judge depth and create a «point cloud» that can be fused together to make a solid object. That solid model is often incredibly accurate down to the smallest crack or imperfection.

But scanning an object can be difficult. The scanner needs to be the right distance from the object you’re scanning at all times, and the object has to be the right color and reflectivity as well. Often, you will need a 3D scanning spray to coat your model in a white, evaporative coating to make scanning easier. This is not possible with human subjects, but does help with inanimate ones. Or at least it should. 

I’ve spent hours using 3D scanners and struggle every time to produce a model that could be 3D printed. Often a scan will lose connection, then restart in the wrong place, causing severe disruption. After a lot of trial and error, I’ve managed to get several usable models, but the amount of work it took just didn’t seem cost-effective. 

Using your iPhone

Pros:

  • Incredibly fast scanning
  • Models are instantly usable as online resources
  • You likely already own one

Cons:

  • Lower detail and quality
  • Can need a lot of clean-up to make it 3D print-ready

iPhones have a lot of cool technology that makes them excellent 3D scanners, including good cameras for photogrammetry and lidar technology for larger objects like cars or the inside of your home. 

Photogrammetry is the best way to create a fully realized 3D model if you want that model to only exist digitally. It uses multiple pictures — the more pictures the better — to create a realistic facsimile of an object. The depth mapping is far rougher than a 3D scanner, but the textures and photo imagery make the model look extremely detailed. As you can see, the shoe in the image above looks identical to the real thing when the textures are shown, but the model I 3D-printed from it has lost a lot of its details.

The coolest thing about photogrammetry, especially on an app like Polycam, is that it can be used with any camera you have, including DSLR cameras and even drones. You simply upload as many images as you want to the Polycam app and it will spit out a 3D rendering of the object you took, whether that’s a shoe or the Grand Canyon. It even works with Android phones, though none of those have the lidar technology like the iPhone.

Lidar only works if you have an iPhone 12 Pro or later, but it’s excellent for scanning larger objects like mailboxes, pool tables and even cars. It works a lot like an expensive 3D scanner — by bouncing light off an object and measuring the distance the light travels — but it has a much lower resolution. This makes it excellent at scanning large, simple objects, especially if you’re keeping them as digital models.

Both photogrammetry and lidar imagery are extremely easy to use on your iPhone and require very little technical know-how to get right. They both need an app though, and after using several different ones, I found Polycam is the best choice.

Polycam costs $80 a year and offers both lidar and photogrammetry. More than that, it uses those systems in some really fun ways. Not only can you scan objects to create 3D models, but you can scan the walls inside your house and build a 3D floor plan. You can even 3D print that floor plan complete with walls, stairs and window and door openings. 

When scanning an object on Polycam for 3D printing I was able to get good quality, low-resolution scans for organic shapes and much better scans of simple objects. Using Polycam to scan a broken sliding door handle was quick and simple and allowed me to accurately replicate a replacement. In fact, if you’re used to using programs like Blender — a free 3D sculpting tool on the PC and Mac — or Nomad Sculpt on the iPad or iPhone, you can import the Polycam file and spruce it up before printing. 

Should you buy a 3D scanner if you own an iPhone?

I’ve spent a lot of time with several different 3D scanners and they all have the same inherent flaw: They’re just too picky to work for consumers. In a commercial setting, where everything can be controlled and your day is dedicated to getting this machine to work perfectly, then sure, a 3D scanner makes sense. If you’re a hobbyist though, with a life that requires more from you than endless hours of slow scanning, an iPhone is a better option.

Even if you don’t own an iPhone, you can pick up an iPhone 12 Pro — the first with lidar — for around $550, several hundred dollars cheaper than a 3D scanner. And once you’re done 3D scanning shoes, mailboxes, cars and houses, you still have an iPhone that can do a hundred other things too.

Before Apple’s Expected iOS 19 Reveal, Here’s What to Know About iOS 18.5

Here are all the new features you should know about in the latest iPhone update.

Apple is holding its Worldwide Developers Conference on June 9, where we will likely get a glimpse of the upcoming iOS 19. Before that announcement, Apple released iOS 18.5 on May 12, more than a month after the company released iOS 18.4. While iOS 18.4 brought more emoji to all iPhones, this latest update adds just a few small changes and a new Pride wallpaper to your iPhone. The update also includes some bug fixes and security patches everyone should download to help keep their device secure. 

Read more: What CNET’s Experts Hope to See in iOS 19

You can download iOS 18.5 by going to Settings > General > Software Update, then tapping Update Now and following the prompts on your screen.

Here’s what iOS 18.5 brings to your iPhone. Just a reminder, only people with an iPhone 15 Pro, Pro Max or the iPhone 16 lineup can access Apple Intelligence for now. If you have any other iPhone, you won’t have access to those features.

New Pride wallpaper

Apple releases a new Pride wallpaper ahead of Pride Month every year, and this year is no different. iOS 18.5 includes the latest iteration of the wallpaper, «Pride Harmony,» which features bold stripes that shift and change position as you move. 

iOS 18.5 tweaks Mail options

Apple introduced a few Mail app updates in iOS 18.5. One of those updates makes it easier to adjust the app’s settings by showing or hiding contact photos in Mail. Contact photos are the images to the left of emails that help identify senders. 

Mail will show Contact Posters by default, but you can turn them off from within the app with iOS 18.5. To do so, open Mail, tap the three dots () in the top-right corner of your screen, and then tap Show Contact Photos. Now, all your emails will just show the subject line and a preview of the message, similar to how Mail looked before iOS 18.

This option is in iOS 18.4, but it’s buried in Settings and not easy to locate. 

Another update concerns Categories. If the mode is enabled, you can see a small tab on the right side of your screen near the other categories. Swipe the categories bar near the top of Mail to the left, and this small tab will expand to reveal the category All Mail. When you swipe left to view All Mail, it will automatically be selected, and you’ll need to tap one of the other Categories to unselect All Mail.

This category isn’t new; you could find it in iOS 18.4. But, there was no small tab on the right side of your screen to signal it was present off-screen. Therefore, All Mail flew under the radar — I didn’t even know the option was there until beta versions of iOS 18.5.

This category appears to be a way to simultaneously enable Categories and List View — the pre-Categories view of Mail. When you use All Mail, you’re viewing your messages without any categorization, like in List View.

Satellite features for all iPhone 13 models

Apple’s iOS 18.5 also brings certain satellite features, like messaging, to the iPhone 13 lineup. That means if you go off the grid, you could still text people to let them know where you are. However, these features on iPhone 13 models are carrier dependent, and currently only T-Mobile offers them in the US via Starlink

T-Mobile Starlink is in beta, and the beta is free and open to anyone until July, including people on other carrier plans. After July, it will be part of the T-Mobile Experience Beyond and Go5G Next plans. People with other carriers, like Verizon and AT&T, will then be able to access the system for $10 a month. 

Back Tap banner

The iOS 18.5 update also introduces the option to display a banner using the Back Tap function. Back Tap turns the Apple logo on the back of your iPhone into a usable button that can open your camera, take a screenshot and more when you double- or triple-tap it. And with iOS 18.5, you can make your iPhone display a banner whenever you use Back Tap.

To enable the banner, go to Settings > Accessibility > Touch > Back Tap and tap the toggle next to Show Banner. If you enable the banner and use Back Tap, the banner will appear across the top of your screen and read, «Back Tap Double/Triple Tap detected.»

iOS 18.5 release notes

Here are the full release notes for iOS 18.5.

This update also includes the following enhancements and bug fixes:

  • A new Pride Harmony wallpaper.
  • Parents now receive a notification when the Screen Time passcode is used on a child’s device.
  • Buy with iPhone is available when purchasing content within the Apple TV app on a third-party device.
  • Fixes an issue where the Apple Vision Pro app may display a black screen.
  • Support for carrier-provided satellite features is available on iPhone 13 (all models). For more information, visit: 
    https://support.apple.com/122339.

Some features may not be available for all regions or on all Apple devices. For information on the security content of Apple software updates, please visit:

These 10 Hacks Could Be the End of Your Terrible Signal Forever

Say goodbye to weak bars with these reception-boosting hacks.

There’s nothing worse than being in the middle of a road trip and realizing your cell signal has dropped out. No GPS, no music and no way to call for help if something goes wrong. A weak signal can cause all kinds of problems, but the good news is that there are a few quick fixes that might get you back online fast.

Whether you’re using an iPhone or Android, these simple hacks can help boost your reception and keep you connected when you need it most.

Whether you’re doing some routine phone maintenance or you’re stuck in an emergency, there are multiple ways to improve your reception on an iPhone or Android phone, no matter what type of phone plan you’re on. It might even come down to something as simple as toggling Airplane mode. 

To go from dropped calls to full bars, here’s what you need to know.

Note: Although software across different iPhone models is relatively the same, Samsung Galaxy, Google Pixel and other Android phones may have different software versions, so certain settings and where they are located might differ depending on device.

For more, check out how you can use Google Maps when you’re offline and how you can maybe fix your internet when it’s down.

To improve your cellphone service, try these steps first

The settings on your phone can help you get better cell service, but there are other tricks for improving your reception without even touching your phone’s software.

  • Move yourself so that there are no obstructions between your phone and any cell towers outside. That might involve stepping away from metal objects or concrete walls, which both kill reception. Instead, get to a window or go outside if possible.
  • Remove your phone case. It doesn’t hurt to remove whatever case you have on your phone, especially if it’s thick, so that the phone’s antenna isn’t blocked by anything and can get a better signal.
  • Make sure your phone is charged. Searching for and connecting to a stronger signal drains power, so if your phone battery is already low on charge, you may have a difficult time getting good service.

Always start by turning Airplane mode on and off

Turning your phone’s connection off and then back on is the quickest and easiest way to try and fix your signal woes. If you’re moving around from one location to another, toggling Airplane mode restarts the Wi-Fi, Bluetooth and cellular network modems, which forces them to find the best signal in the area.

Android: Swipe down from the top of your screen — to access the Quick Settings panel — and then tap the Airplane mode icon. Wait for your phone to completely disconnect from its Wi-Fi and cellular connections. It doesn’t happen instantly, so give it a good 15 seconds before you tap on the Airplane mode icon again.

iPhone: On the iPhone, you can access Airplane mode from the Control Center, but that varies depending on which iPhone model you have. On the iPhone X and later, swipe down from the top-right corner to access the Control Center. On older iPhone models, swipe up from the bottom of the screen. Then tap the Airplane mode icon, which will turn orange when it’s enabled. Again, wait up to 15 seconds before turning it off.

If Airplane mode doesn’t work, restart your phone

Our phones are miniature computers, and just like computers, sometimes you can fix issues like network connection by simply restarting them.

Android: Hold down the power button, or the power button and the volume down key (depending on your Android phone), until the on-screen menu shows up, and then tap Restart. If your phone doesn’t offer a restart option, you can simply tap Power Off to shut down your device, and then boot it back up with the power button.

iPhone: On the iPhone X and older models, hold down the sleep/wake button and either one of the volume buttons and then swipe right on the power slider to turn off the device. Wait until it fully turns off, then press down on the sleep/wake button to turn it back on. 

Alternatively, you can do a force reset on your iPhone: Press the volume up button, followed by the volume down button and then press and hold the side button. Keep holding it in, after your phone’s screen goes black and until you see the Apple logo appear again. 

If your iPhone has a home button, hold down the sleep/wake button until the power slider is displayed and then drag the slider to the right. Once the device is turned off, press and hold the sleep/wake button until you see the Apple logo. 

Older phone? Take your SIM card out

Another troubleshooting step that might help is to remove your SIM card, if your phone has one, and then place it back in with the phone turned on. If the SIM card is dirty, clean it. If it has any physical defects, you may need to replace it.

You’ll need a SIM card tool — usually included in your phone’s box — or an unfolded paper clip or sewing needle to get the SIM tray out of your phone.

All phones: Remove the SIM card, check to see if it’s damaged and positioned in the SIM tray correctly, then put it back in your phone.

eSIM: For phones with an eSIM — that is, an embedded electronic SIM in your phone — there’s nothing for you to remove. The best you can do is restart your phone.

Check your carrier settings (and update your software)

Mobile carriers frequently send out carrier settings updates to help improve connectivity for calls, data and messages on their network. Although this feature is available on all iPhone models, it’s not universal on Android, so you might not find carrier settings if you don’t have a supported phone.

iPhone: Carrier updates should just appear, and you can update from the pop-up message that appears. To force your iPhone to check for a carrier settings update, go to Settings > General > About on your phone. If an update is available, you’ll be prompted to install it.

Android: As mentioned before, not all Android phones have carrier settings, so you’ll have to open the Settings app and type in «carrier settings» to find any possible updates. On supported Pixels, go to Settings > Network & internet > Internet, tap the gear next to your carrier name and then tap Carrier settings versions.

Reset your phone’s network settings

Sometimes all you need is a clean slate to fix an annoying connectivity issue. Refreshing your phone’s network settings is one way to do that. But be forewarned, resetting your network settings will also reset any saved Wi-Fi passwords, VPN connections and custom APN settings for those on carriers that require additional setup.

Android: In the Settings app, search for «reset» or more specifically «reset network settings» and tap on the setting. On the Pixel, the setting is called Reset Wi-Fi, mobile & Bluetooth. After you reset your network settings, remember to reconnect your phone to your home and work Wi-Fi networks.

iPhone: Go to Settings > Transfer or Reset iPhone > Reset > Reset Network settings. The next page will warn you that resetting your network settings will reset your settings for Wi-Fi, mobile data and Bluetooth. Tap Reset Network Settings and your phone will restart.

Contact your phone carrier

Sometimes unexpected signal issues can be traced back to problems with your wireless carrier. A cell tower could be down, or the tower’s fiber optic cable could have been cut, causing an outage.

For consistent problems connecting to or staying connected to a cellular or data network, it’s possible your carrier’s coverage doesn’t extend well into your neighborhood. 

Other times, a newfound signal issue can be due to a defect with your phone or a SIM card that’s gone bad. Contacting your carrier to begin troubleshooting after you’ve tried these fixes is the next best step to resolving your spotty signal.

If all else fails, try a signal booster to improve cell reception

If after going through all of our troubleshooting steps, including talking to your carrier to go over your options, you’re still struggling to keep a good signal — try a booster. A signal booster receives the same cellular signal your carrier uses, then amplifies it just enough to provide coverage in a room or your entire house. 

The big downside here is the cost. Wilson has three different boosters designed for home use, ranging in price from $349 for single room coverage to $999 to cover your entire home. To be clear, we haven’t specifically tested these models. Wilson offers a 30-day money-back guarantee and a two-year warranty should you have any trouble with its products.

Your iPhone Has 23 Settings That Could Make Your Life Way Easier

Small changes in your iPhone’s settings can make a big difference in how it works.

If you haven’t taken a closer look at your iPhone settings lately, you’re probably missing out on features that could save time, reduce distractions, and personalize your experience in a big way. Every iOS update quietly adds tools and upgrades that make your phone smarter and easier to use — but only if you know where to find them.

Apple continues to expand what your iPhone can do, from smarter notification controls to an upgraded Siri that feels more like an assistant and less like a voice search. There are also simple ways to clean up your camera roll, automate your daily routines, and cut down on the digital noise that slows you down.

From decluttering your home screen to maximizing battery life, we’ve rounded up 23 iOS settings that let you take full control of your device. Some you may already know, and others that might surprise you.

Take a Closer Look at the iOS Settings You Should Change Right Now

See all photos

1. Stop apps from tracking your exact location

Apps like Doordash and Postmates require your exact location to deliver food to the right location or directly to you. That doesn’t mean every application on your iPhone needs to know precisely where you are at every moment. That’s why you can prevent an app from tracking your exact location. 

In the Settings app, choose an application (like Instagram, for example), tap Location and then toggle off Precise Location. Any app with Precise Location off will only know your approximate location, within a few miles.

2. Turn the back of your iPhone into a button

The back of your iPhone can be used as a secret button to activate certain actions such as taking a screenshot, enabling low power mode or running a shortcut that can automatically play music when you arrive at the gym. The Action Button on the iPhone 14 Pro and Pro Max, iPhone 15 and 15 Plus, and iPhone 15 Pro and Pro Max models do the same, but if you have an older model, the back of your iPhone works.

The option is hidden deep in your settings; here’s how to find it.

In the Settings app, go to Accessibility > Touch > Back Tap and choose one of two options: double tap or triple tap. You should see a list of actions you can run by tapping the back of your iPhone, like opening your camera, turning on the flashlight and scrolling up and down. Tap an action or shortcut to enable it with Back Tap.

3. Enable Live Voicemail to get real-time voicemail transcriptions

You get a call and don’t want to necessarily pick up unless it’s important. Unfortunately, the only way you’ll know is if you listen to a voicemail left after the call. With iOS 17, you can read a real-time transcription of any voicemail being left. That’s right: If someone is leaving you a voicemail, you can read it on your phone and choose to pick up the call, connecting you with the person leaving the voicemail.

The Live Voicemail feature isn’t on by default, so go to Settings > Phone > Live Voicemail and turn it on. That’s it.

4. Bring back full-screen incoming call alerts

If your iPhone is unlocked and you receive a phone call, a banner-style notification appears at the top of your screen, with a small photo and name or number of the person calling, and the options to pick up or deny the call. 

This wasn’t always the default option. In the past, incoming calls would take over your entire display when your iPhone was unlocked. It was disruptive, sure, but it also got the job done. The banner may be a welcome change for many because it’s more discreet and allows you to use your phone while receiving a call. 

If for any reason you’re not a big fan of the banner and want to revert to the more attention-grabbing full-screen alert, go to Settings > Phone > Incoming Calls and tap Full Screen.

5. Turn off 5G coverage you don’t want or have

Apple touts a Smart Data feature that’s specific to its 5G phones that will automatically switch between 4G LTE and 5G networks based on how you’re using your device. You may find that your iPhone’s battery drains faster than it did before. If you don’t want to sacrifice battery life for faster 5G speeds, shut it down. You can always turn 5G back on when you want it, or when service in your area improves.

To turn off 5G on your iPhone, forcing it to always use 4G LTE (even if you have 5G coverage), open the Settings app, then go to Cellular > Primary > Voice & Data and tap LTE. Alternatively, if you want your iPhone to exclusively use a 5G connection when available, you can select 5G On.

6. Fine-tune how much data is used by a 5G connection

If you’re happy with your 5G performance, here’s a network-related setting you should check out. Go to Settings > CellularPrimary > Data Mode, where you’ll find three options: Allow More Data on 5G, Standard and Low Data Mode.

Even though you can read brief descriptions below the three settings, they don’t paint a complete picture of the first option. According to an Apple support document, allowing more data on 5G will give you high-quality video and FaceTime calls. It also lets your phone download software updates and stream high-definition Apple TV and Apple Music content, and it allows third-party developers to improve their respective apps.

The default setting on this page will depend on your carrier and data plan, so it’s a good idea to check your iPhone and make sure it’s correctly set to your preference.

7. Stop apps from cluttering up your home screen

The App Library is a place where you can quickly find and access all of your applications. And while apps are housed here, all newly downloaded apps also appear on your home screen. This may not be a problem if you download apps sparingly, but if you’re installing new apps on a consistent basis, they can quickly clutter up your home screen.

To stop downloaded apps from appearing on your home screen, go to Settings > Home Screen & App Library and select App Library Only. If you want to find the app, you’ll have to swipe left on your home screen until you reach the App Library.

8. Unlock your phone while wearing a face mask

If you wear a mask in public, unlocking your iPhone with Apple’s Face ID technology can be frustrating. Because half of your face is covered, Face ID just doesn’t work. And while entering your passcode to unlock your phone works, it’s not as convenient. 

With iOS, you have the option to turn on a face unlock feature that makes it easy to unlock your iPhone when you’re wearing a face mask. Before the update, you could only unlock your iPhone if you owned an Apple Watch. 

To unlock your iPhone with your Apple Watch, open the Settings app on your iPhone and then open the Face ID & Passcode option. Scroll down until you find the Unlock with Apple Watch section (you must be connected to an Apple Watch for the setting to appear), where you can turn on the feature for any watches linked to your iPhone. 

If you have an iPhone running iOS 15.4 or later, you can unlock your iPhone while wearing a mask without an Apple Watch. Go to the Settings app and open Face ID & Passcode. From there, you can toggle on the Face ID With a Mask option. It’s pretty awesome. 

9. Put the address bar in Safari back on top

The address in Safari migrated to the bottom of the screen a few years back; welcome for those with smaller hands who had difficulty reaching it with one hand at the top. This move might feel more natural, since it’s closer to the keyboard and where you typically place your thumbs, it can be off-putting since some people are used to seeing the URL bar near the top of the screen.

If you want to put the address bar back at the top of the screen, go to Settings, tap Safari and choose the Single Tab option under the Tabs subheading.

10. Add features that can be used when your iPhone is locked

There are times when you might want to have certain info handy even when your phone is locked. That’s why Apple allows you to enable some features without having to unlock your devices, such as the notification center, Control Center, the ability to reply to messages and the Wallet app.

To customize the features you’d like to access on the lock screen, launch the Settings menu, tap Face ID & Passcode and enter your passcode when prompted. Scroll down until you see the Allow Access When Locked section, and toggle the sliders based on your preferences. 

11. Make your favorite email app or web browser your default

It’s not all about Safari. On your iPhone, you have the ability to choose your own default apps, at least for email and web browsing. That means that when you tap a link or an email send button, your iPhone will automatically launch the web browser or email provider of your choosing rather than Safari or Mail. 

To get started, open the Settings menu and select the app you’d like to set as a default (such as Google Chrome or Outlook). You should then see a button that says Default Mail App or Default Browser App. Tap that option and select the app of your choosing instead of Safari or Mail.

12. Get full notifications on your lock screen

The first time you experience Apple’s Face ID tech, you’ll notice that you can’t see the content of new alerts and notifications on the lock screen. For example, instead of seeing who sent you a text message and what it says, you’ll only see a generic Messages alert.

By default, all iPhones with Apple’s Face ID tech will hide the content of an alert until you pick up your phone and unlock it. It’s a privacy feature that I rather enjoy, but I also understand how it could be annoying (I’ve heard a few complaints from readers and family members alike).

You can change how notifications appear on your lock screen by going to Settings > Notifications > Show Previews and selecting Always. Conversely, you can select Never if you want to keep the content of your notifications always hidden from the lock screen.

13. Turn off (or on) HDR video for sharing videos

The iPhone can record high dynamic range (HDR) video with Dolby Vision. That means your videos are typically brighter, with more accurate colors and improved contrast. That may be ideal for some, but if you don’t want videos that are automatically adjusted because you want to do it on your own, there is a way to disable the feature.

You can turn off HDR video by going to Settings > Camera > Record Video and turning the switch next to HDR Video to the Off position. Going forward, all videos will be captured in the standard dynamic range.

14. Customize your home screen with fancy wallpaper

Another home screen tweak you should make involves your wallpaper or background. Apple has many wallpapers of its own, with a pretty cool twist. 

Open the Settings app on your iPhone and select Wallpaper from the list. Make sure the switch labeled «Dark Appearance Dims Wallpaper,» which you’ll see below the two thumbnail previews of your wallpaper, is turned on. Now, tap Choose a new wallpaper and select either Stills or Live. Look for the circle near the bottom of each wallpaper. It’s half black, half white. 

That circle means that the wallpaper has both light and dark mode versions and will change automatically based on the system status of your phone. 

You can also set live wallpapers as your background if you’re not sold on dark and light mode.

15. Turn on dark mode to save your battery

Speaking of dark mode, if you don’t want to have to repeatedly adjust your screen’s brightness, you can use your phone’s dedicated dark mode. Dark mode converts all of the white backgrounds in apps to, more often than not, a black background. In turn, your phone is able to save battery power thanks to the darker colors. 

Turn it on by going to Settings > Display & Brightness and selecting the Dark option at the top of the screen. You can also just swipe down from the top-right of your iPhone and tap the Dark mode icon in the Control Center.

Apple’s apps will automatically switch to a dark color scheme, and most third-party apps have also adopted the feature. 

16. Manage your notifications with Focus Mode

We get a lot of notifications every day, but not all of them are relevant all the time. That’s why Apple introduced a feature called Focus Mode. Think of it as a custom Do Not Disturb feature that’s tailored to specific circumstances. 

Focus Mode blocks less relevant alerts while allowing notifications from important people and apps to come through so that you don’t miss anything. You can set up different types of Focus Modes for specific circumstances. 

Apple currently offers options for Do Not Disturb, personal, sleep, work, driving, fitness, gaming, mindfulness and reading, but you can also create your own custom mode. You can schedule Focus Modes so that they turn on automatically when needed and display your status in apps so that others know you have notifications silenced. 

To get started, open the Settings menu, tap Focus and choose one of the available options to set up your notification preferences. Tap the plus (+) symbol in the top right corner to add a new Focus. 

17. Make your screen text bigger or smaller

With a couple of taps on your iPhone’s screen, you can adjust the font size to make it easier to read. Open Settings and go to Display & Brightness > Text Size where you can use the slider until you’re happy with the font size. For a little added oomph, you can turn on Bold Text (it’s just below the Text Size button). 

18. Add an alternate appearance to Face ID

Apple’s facial recognition feature, Face ID, constantly learns different aspects of your face with each scan. If you’re struggling to get Face ID to consistently recognize you, try the Alternate Appearance option. 

Go to Settings > Face ID & Passcode > enter your PIN > Set Up An Alternate Appearance and go through the process of enrolling your face again. 

19. Disable auto-brightness for longer battery charge

Your iPhone’s screen brightness level can have a big impact on battery life. By default, iOS will automatically adjust the display’s brightness based on how much light its ambient sensor detects. If you want to take complete control, you can disable auto brightness, meaning the brightness level will stay where you set it until you adjust it again. 

Open Settings > Accessibility > Display & Text Size and at the bottom of the page, you’ll find a switch to turn off Auto-Brightness

Now, whenever you want to adjust your screen, you can do so by opening Control Center with a swipe up from the bottom of the screen on a device with a home button, or a swipe down from the top-right corner on newer iPhones. 

20. Triage your privacy settings

The first time you set up an iPhone with all of your apps, you’re bombarded with prompts asking for permission to access personal information ranging from tracking your location to your Apple Health information or your camera roll. 

It’s far too easy to get in the habit of approving everything just so you can use the app, but take a few minutes and go through your privacy settings to tailor what each app can and can’t see. We walk you through the whole privacy process in two quick steps. 

21. Use the Control Center to access apps with a swipe or tap

The iPhone’s Control Center is a convenient spot to quickly change songs, turn on airplane mode, connect to Wi-Fi or start a timer, but there’s so much more to it than that. You can quickly turn on your flashlight, check on a timer or start recording your screen with a quick swipe and tap. 

Customize which apps and features are available in Control Center by opening Settings > Control Center. Remove an option with a tap on the red minus button or add an option by selecting the green addition button. Drag features up or down using the three-line icon on the right side of the screen. 

I like having quick access to the Wallet app and toggles for low-power mode and dark mode. 

As a reminder, if you have an iPhone with a home button, like the iPhone SE, you can swipe up from the bottom of the screen to open Control Center. If you have an iPhone with Face ID, you’ll need to swipe down from the top-right corner of the screen where the battery icon is. 

22. Organize alerts with Notification Summary

Apple wants to help you manage your notifications in iOS, starting with the Notification Summary feature. Rather than letting notifications pile up on your home screen, you can schedule alerts that aren’t urgent to arrive in a bundle at a specific time of day. 

Important notifications like calls, direct messages and other time-sensitive alerts (like the status of your Uber or Lyft ride, for example) will still appear immediately.

To try this out, open Settings, press Notifications and tap Scheduled Summary

23. Change Siri’s voice

If you’ve recently set up a new iPhone, you may have noticed that Siri no longer defaults to a female voice. Instead, you’ll be asked which Siri voice you want to use, including several more recent options. Once you’ve made your selection, Apple will change Siri’s voice across all of the devices linked to your Apple ID.

You can check out the voice options by going to Settings > Siri & Search > Siri Voice. To learn more, check out our complete guide to changing Siri’s sound. Apple also added a gender-neutral Siri voice option for English speakers.
