The 20 iPhone Settings That Actually Matter

The 60-Second Version

If you do only a few things from this guide, make it these. Each one takes a minute and makes the phone easier to live with every single day.

• Make the text bigger: Settings, Display & Brightness, Text Size.
• Turn the ringer volume up so you never miss a call.
• Pick a ringtone you can actually hear from the next room.
• Turn on automatic updates so your phone stays safe on its own.
• Turn off notifications for apps that pester you and keep the ones that matter.

Where Settings Lives

Every switch in this guide lives in one place: the Settings app. Let's make sure you can always find it and get to any setting quickly.

Once Settings is open, there is a search box at the very top. If you cannot remember where a setting lives, pull down gently to reveal that box, type a word like text or ringtone, and tap the result. This saves a lot of hunting through the long list.

• Look for the gray icon with gears on it — that is Settings.
• It is usually on your Home Screen or tucked in a folder.
• If you cannot find it, swipe down the middle of the Home Screen to open Search, type Settings, and tap it.
• The search trick works for any app you have misplaced.

Making Text Bigger and Bolder

If you find yourself squinting or holding the phone at arm's length, this is the first setting to change. Bigger, bolder text makes everything easier to read.

Back on the Display & Brightness screen, turn on Bold Text. It makes the letters thicker and easier to see without making them larger. Many people find this alone makes a big difference.

• Open Settings, then tap Display & Brightness.
• Tap Text Size.
• Drag the slider at the bottom to the right to make text bigger.
• The sample text above changes as you slide, so you can find your comfortable size.

Brightness and Auto-Lock

Two settings control how bright your screen is and how quickly it turns itself off. Getting these right saves your eyes and your battery.

Auto-Lock is how long the screen stays on before it dims and locks. In Display & Brightness, tap Auto-Lock and pick a time. If your screen keeps going dark while you are reading, choose a longer time like 2 or 3 minutes. A shorter time saves battery but can feel rushed.

• Open Settings, then Display & Brightness.
• Drag the Brightness slider to a level that is comfortable for your eyes.
• Leave True Tone on — it gently adjusts the color to the light around you.
• You can also change brightness quickly from Control Center, which we mention on page 16.

Ringtone, Volume, and Vibration

There is no point in a phone you cannot hear ring. Let's make sure your calls and texts come through loud and clear.

On the same screen, tap Ringtone and try a few. Choose one that is bright and easy to hear from another room — some of the older, gentler tones are easy to miss. Tap one to hear it, and tap the blue back arrow to keep it.

• Open Settings, then Sounds & Haptics (it may just say Sounds).
• Under Ringtone and Alert Volume, drag the slider well to the right.
• Turn off Change with Buttons so the side buttons cannot accidentally turn your ringer down.
• With that off, your ringer stays at the level you set here.

Sounds and Haptics

Beyond the ringer, your phone can make sounds and gentle buzzes for texts, emails, and other alerts. You get to decide which ones you want.

Haptics are the small taps and vibrations you feel. They are handy if you keep your phone in a pocket where you might not hear it. In Sounds & Haptics you can turn vibration on or off for both ring and silent modes. If the buzzing bothers you, it is fine to turn it down.

• In Settings, open Sounds & Haptics.
• Tap Text Tone to choose the sound for new text messages.
• Scroll down to set sounds for New Mail, Calendar Alerts, and more.
• Pick a distinct text tone so you can tell a message from a call without looking.

Which to Keep, Which to Silence

Notifications are the little messages and badges that pop up all day. Used well, they help. Left alone, they overwhelm. Let's tidy them up.

Leave notifications on for the things you truly want to know about — Messages, Phone, and perhaps your calendar or a medication reminder. The goal is not to silence everything, but to make sure the only things that grab your attention are the things worth it.

• Open Settings, then tap Notifications.
• Scroll to find the app that keeps bothering you and tap it.
• Turn off Allow Notifications to silence it completely, or leave it on and turn off the Sounds and Badges.
• Repeat for any app that interrupts you without good reason.

Do Not Disturb and Focus

Sometimes you just want quiet — during a nap, a meal, or overnight. Do Not Disturb hushes your phone for a while, and you decide when.

You can set Do Not Disturb to still allow calls from certain people, so an emergency from family always rings. In Settings, tap Focus, tap Do Not Disturb, and under People choose who is allowed to reach you. This gives you quiet without cutting off the ones who matter.

• Open Control Center: swipe down from the top-right corner of the screen.
• Tap the Focus button (it may show a crescent moon).
• Choose Do Not Disturb to silence calls and alerts until you turn it back off.
• The crescent moon shows at the top of your screen while it is on.

Wi-Fi and Joining a Network

Wi-Fi is how your phone connects to the internet through your home network. Being on Wi-Fi at home is faster and does not use up your cellular data.

A blue checkmark appears next to your network name when you are connected, and a small fan-shaped Wi-Fi icon shows at the top of your screen. Once your phone knows your network, it joins automatically every time you come home — you will not have to type the password again.

• Open Settings, then tap Wi-Fi.
• Make sure the switch at the top is on (green).
• Tap the name of your home network in the list.
• Type the password once, and your phone will remember it from then on.

Wi-Fi vs. Cellular Data

When you are away from home, your phone uses cellular data — the internet from your phone company. Knowing the difference helps you avoid surprise charges.

If your plan has a data limit, you can control which apps use cellular. Open Settings, tap Cellular, and scroll to the list of apps. Turning a heavy app off there means it will only work on Wi-Fi. For most folks with an unlimited plan, there is nothing to worry about here.

• Wi-Fi comes from your home internet and does not count against your phone plan.
• Cellular data comes from your phone company's towers and is part of your monthly plan.
• Your phone uses Wi-Fi when it can and switches to cellular when you are out.
• You will see either the Wi-Fi fan or letters like 5G at the top of the screen.

Bluetooth

Bluetooth is how your phone talks to nearby gadgets without wires — hearing aids, wireless earbuds, a car radio, or a speaker. It is worth understanding, because so many devices use it.

Many modern hearing aids connect over Bluetooth so calls and sound play right into your ears. If you wear Made for iPhone hearing aids, look in Settings, Accessibility, Hearing Devices to pair and adjust them. This can be life-changing on phone calls — well worth setting up.

• Open Settings, then tap Bluetooth and make sure it is on (green).
• Put your device — earbuds, hearing aids, speaker — into pairing mode (check its instructions).
• Wait for it to appear under Other Devices, then tap its name.
• Once connected, it moves up under My Devices and reconnects on its own next time.

Location Services

Location Services lets certain apps know where you are — helpful for maps and weather, but not something every app needs. Let's set it sensibly.

Maps, weather, and Find My genuinely need your location to do their job. A game or a shopping app usually does not. If you are unsure, set an app to While Using — it can still work, but only knows where you are while it is open on your screen.

• Open Settings, tap Privacy & Security, then Location Services.
• Make sure the top switch is on so maps and weather can work.
• Tap any app to choose when it may see your location: Never, Ask Next Time, While Using, or Always.
• For most apps, While Using the App is the sensible, private choice.

The Keyboard and Predictive Text

Typing gets much easier once the keyboard is set up to help you. A few settings can cut down on typos and speed things along.

If typing is a chore, you can talk instead. Tap the small microphone on the keyboard, then simply speak — your words appear as text. It is wonderful for longer messages. Say the words period or comma to add punctuation as you go.

• Open Settings, tap General, then Keyboard.
• Turn on Predictive so the phone suggests the next word above the keys.
• Turn on Auto-Capitalization so sentences start with a capital letter.
• If autocorrect changes words you do not want, you can turn Auto-Correction off here.

Dark Mode and Easy-on-the-Eyes Display

Your iPhone can change its whole look to suit your eyes and the time of day. These settings are all about comfort.

Night Shift warms the screen colors in the evening, which many people find gentler before bed. In Display & Brightness, tap Night Shift and set a schedule, such as sunset to sunrise. It is a small change that can help tired eyes.

• Open Settings, then Display & Brightness.
• At the top, choose Light for a bright, white look or Dark for a black background.
• Dark is easier on the eyes at night; Light is clearer in bright rooms.
• Turn on Automatic to let it switch by itself at sunset and sunrise.

Battery and Low Power Mode

A little know-how keeps your battery lasting through the day. These settings help you see where the power goes and stretch it when you need to.

It helps to see the exact battery number, not just the icon. In Settings, tap Battery and turn on Battery Percentage so a number shows in the top corner. Then you always know at a glance whether it is time to plug in.

• Open Settings, then tap Battery to see how much you have used today.
• Turn on Low Power Mode when the battery is running low to make it last longer.
• Low Power Mode dims the screen a touch and pauses some background activity.
• The battery number turns yellow while Low Power Mode is on, and green again when charged.

Face ID and Your Passcode

Your passcode and Face ID keep your phone yours. It is worth understanding them, because they protect everything on the device.

Face ID may not recognize you in the dark, at an odd angle, or with something covering your face. When that happens, your phone simply asks for your passcode instead — so you are never locked out. That passcode is your reliable backup; make sure it is one you will remember.

• Your passcode is the number you type to unlock the phone — keep it private.
• Face ID lets you unlock just by looking, using a scan of your face stored only on your phone.
• Find both in Settings under Face ID & Passcode (you will enter your passcode to open it).
• You can set up an alternate appearance so Face ID knows you with and without glasses.

Emergency SOS (A Pointer)

Your iPhone can call for help fast and show a responder your health details. This page points you to it — and I have a full guide dedicated to setting it up properly.

This is the kind of thing best done calmly, ahead of time, rather than in a crisis. Filling in your Medical ID and adding emergency contacts takes about half an hour and can matter enormously on a hard day.

• Open Settings and tap Emergency SOS to see the call options.
• Open the Health app and tap your photo, then Medical ID, to add your conditions and contacts.
• In Medical ID, turn on Show When Locked so responders can see it without your passcode.
• To call for help: press and hold the side button and a volume button until the sliders appear.

Keeping iOS Up to Date

Software updates keep your iPhone safe and working smoothly. The easiest approach is to let your phone handle them for you, overnight.

Updates fix problems and close security holes that scammers try to use. They usually install overnight while your phone is charging and on Wi-Fi, so you wake up to a phone that is a little safer. There is no reason to fear them — this is good housekeeping for your phone.

• Open Settings, tap General, then Software Update.
• Tap Automatic Updates.
• Turn on Download and Install so updates arrive on their own.
• Turn on Security Responses so urgent safety fixes install quickly.

Settings to Leave Alone

Most settings are safe to explore, but a few are best left as they are unless you know why you are changing them. Here is what to steer clear of.

A good rule: if you do not understand what a setting does, leave it as it is. You will not miss out on anything by being cautious, and you avoid the small chance of turning something off that you need. When in doubt, ask before you switch.

• Reset options under General, Transfer or Reset iPhone — Erase All Content wipes the whole phone.
• VPN and Device Management under General — leave these alone unless a trusted person set them up.
• Turning off Find My iPhone — keep it on so a lost phone can be found and stays protected.
• Changing your Apple Account email or password unless you are certain and have written it down.
