Complete iPhone Setup Guide

Introduction: from unboxing to mastery

Proper setup is essential if you want to get the most from a new iPhone. Apple’s iOS software offers several ways to transfer data, secure your account and personalize the interface. By following a structured approach, you’ll avoid headaches like missing contacts, weak passwords or confusing notifications. This guide, written for 2025, walks you through the entire setup process – from preparing your old phone to customizing your new one. It references official Apple instructions for data migration and draws on privacy recommendations from the Electronic Frontier Foundation (EFF) so you can enjoy your iPhone while keeping your information safesupport.apple.comssd.eff.org.

Step 1 – Prepare your old device and create a backup

Before you even turn on your new iPhone, make sure your old phone is ready. Take these preparatory steps:

Charge both phones and connect them to power. Data transfers can take a while.
Check your Apple ID credentials. You’ll need your password and possibly a verification code for two‑factor authentication. If you’ve forgotten the password, reset it ahead of time.
Update your current phone to the latest version of iOS. Apple advises having both devices on current software to ensure compatibility when using Quick Startsupport.apple.com.
Back up your old device. Go to Settings > [your name] > iCloud > iCloud Backup and tap Back Up Now, or back up to a Mac/PC using Finder or the Apple Devices app. A fresh backup ensures you can restore data even if something goes wrong.
Gather your SIM details. If you plan to keep your number, remove the SIM card or contact your carrier to move your line to an eSIM.

Step 2 – Transfer data: Quick Start, iCloud or manual setup

When you turn on a new iPhone, the setup assistant asks how you want to configure it. There are three main options: Quick Start, Restore from backup and Set up manually.

Use Quick Start for device‑to‑device transfer

Quick Start is Apple’s built‑in tool for moving all your data from an old iPhone or iPad to your new device. You’ll need both devices running at least iOS 11/iPadOS 13. Here’s how it works:

Place your old phone next to the new one with Wi‑Fi and Bluetooth enabled.

An animation will appear on the new phone. Scan it with the old device to pair them.

Follow onscreen instructions to confirm your Apple ID and to create a passcode for the new device.

Connect to Wi‑Fi or cellular. You might be asked to activate your cellular servicesupport.apple.com.

Choose whether to Download from iCloud or Transfer directly. Downloading from iCloud lets you start using your phone sooner because apps and data download in the background. Direct transfer requires leaving both devices near each other until the process finishessupport.apple.com.

Keep devices connected to power until migration completessupport.apple.com.

Restore from iCloud or Finder backup

If you’ve previously backed up to iCloud or your computer, choose Restore from iCloud Backup or Restore from Mac/PC. Sign in with your Apple ID and pick the most recent backup. Using a Mac or PC, connect your new iPhone via USB, open Finder or the Apple Devices app, select the device and choose Restore Backup.

Set up manually as new or transfer from Android

If you prefer a fresh start, select Set Up as New iPhone. You’ll create a new passcode and sign into your Apple ID. Switching from Android? Download the Move to iOS app on your old Android phone and follow instructions during setup to transfer contacts, photos and messages.

Step 3 – Secure your device: passcode, Face ID/Touch ID and Apple ID

A strong foundation starts with security. iOS encrypts your data, but that protection is only effective when you use a solid passcode and secure your Apple ID. The EFF recommends two essential measures: using a strong passcode and enabling biometric loginssd.eff.org.

Create a strong passcode: Go to Settings > Face ID & Passcode (or Touch ID & Passcode) and choose Custom Numeric or Custom Alphanumeric Code. Aim for at least eight characters. Avoid simple numbers like 1234.

Set up Face ID or Touch ID: Follow the onscreen prompts to register your face or fingerprint. Biometrics make unlocking more convenient, but EFF notes that passcodes may provide stronger legal protection if authorities try to compel you to unlock your phonessd.eff.org.

Enable two‑factor authentication (2FA): In Settings > [your name] > Sign‑In & Security, tap Two‑Factor Authentication and follow the steps. 2FA ensures that even if someone learns your password, they cannot access your Apple ID without a verification codessd.eff.org.

Review trusted devices: In the same menu, remove any devices you no longer own. High‑risk users can add hardware security keys for added protectionssd.eff.org.

Step 4 – Review privacy settings and permissions

After securing your Apple ID, audit your privacy settings. iOS asks for many permissions – camera, microphone, location, contacts, photos – and it’s easy to forget what you’ve allowed. The EFF recommends periodic reviewsssd.eff.org.

Open Settings > Privacy & Security. You’ll see categories showing how many apps can access each type of data. Tap each category to review and revoke permissions.
Location Services: Decide whether an app can access your location Never, Ask Next Time, While Using the App or Always. You can also choose Precise or Approximate locationssd.eff.org.
Contacts & Photos: Select Full Access, Limited Access, Add Only or None for each appssd.eff.org. Limiting access helps prevent accidental uploads or data leaks.
Disable ad tracking: Under Tracking, turn off Allow Apps to Request to Track to stop cross‑app tracking.
Find My and Stolen Device Protection: Turn on Find My iPhone under Settings > [your name] > Find My and enable Send Last Location. If you use iOS 17.3 or later, enable Stolen Device Protection, which adds a delay to sensitive actions when your phone is away from familiar locations.

Step 5 – Customize your iPhone (display, home screen and Control Center)

Personalizing your new iPhone makes it more comfortable to use. While iOS 18 offers countless customization options, here are key areas to tweak:

Display and brightness

Dark Mode: In Settings > Display & Brightness, choose Dark or schedule Dark Mode to turn on automatically at sunset.

True Tone and Night Shift: Enable True Tone to match the screen’s color temperature to ambient light, and schedule Night Shift to reduce blue light in the evening.

Text size: Adjust text size in the same menu or add a Text Size control to Control Center for quick changes.

Home screen and widgets

App Library: Swipe left past your last home screen to access the App Library. Long‑press an app icon and tap Remove from Home Screen to hide it (the app remains in the library).

Add widgets: Long‑press an empty area of the home screen, tap + and select widgets (Calendar, Weather, Photos, Battery). Customize their size and position. You can create Smart Stacks that rotate through multiple widgets automatically.

Lock Screen: Press and hold the lock screen to customize wallpapers, fonts and widgets. You can create multiple lock screens and link them to Focus modes.

Control Center

Go to Settings > Control Center to add or remove controls. Consider adding Low Power Mode, Screen Recording, Flashlight, Timer or Text Size. Reorder controls by dragging them up or down.

Step 6 – Enable core Apple services (iCloud, Siri, Wallet and Health)

iCloud synchronization

Sign into iCloud (Settings > [your name]) and choose which services to sync – photos, contacts, calendars, notes and Safari. Enabling iCloud Keychain securely stores and syncs passwords across Apple devices.

Set up Apple Pay and Wallet

Open the Wallet app, tap + and add your credit or debit cards by following your bank’s verification steps. You can also add transit cards, loyalty cards, car keys and hotel keys.

Configure Siri

In Settings > Siri & Search, enable Listen for “Hey Siri” and run through the voice‑training prompts. Customize Siri’s responses (spoken or silent) and decide which apps can show Siri Suggestions. Turning on Announce Notifications lets Siri read messages over headphones or CarPlay.

Emergency contacts and Medical ID

Open the Health app, tap your profile picture and create a Medical ID. Add allergies, medical conditions and emergency contacts. Enable Share During Emergency Call so first responders receive this information automatically. In Settings > Emergency SOS, configure how to trigger SOS calls (e.g., press and hold the side button or rapidly press it five times).

Step 7 – Organize apps and explore productivity tools

Once your iPhone is up and running, visit the App Store to download essentials and re‑install previous purchases (look under Purchased). You can keep your phone tidy by using folders and the App Library, and by enabling Offload Unused Apps in Settings > App Store so iOS removes rarely used apps while retaining their data. Turning on Automatic App Downloads will install any new apps you buy on other devices automatically. To minimize interruptions, experiment with Focus modes (Work, Personal or Sleep) in Settings > Focus and link them to custom lock screens. Productivity features like AirDrop, Universal Clipboard and Handoff help you share data across Apple devices instantly. Long‑press icons in Control Center to reveal hidden options, such as adjusting flashlight brightness or setting a quick timer.

Step 8 – Stay updated and maintain your iPhone

After setup, maintain your iPhone for performance and security. Turn on Automatic Updates under Settings > General > Software Update, keep backing up to iCloud or a computer, and enable Optimised Battery Charging in Battery Health & Charging to slow battery aging.

Manage storage under Settings > General > iPhone Storage: offload unused apps, move photos to cloud storage or an external drive and clear Safari history to free space and keep your phone responsive.

Check your notification settings in Settings > Notifications to choose which alerts appear. Use Focus modes to filter notifications during work, study or sleep, and schedule summaries for less urgent updates. Audit these settings often to keep your iPhone helpful, not distracting.

Periodically review Apple’s release notes to discover new features introduced with each major iOS update. Apple often adds hidden gems, such as improved widgets, and staying curious in the Settings app will help you find options you didn’t know existed. For example, new updates may bring Live Text improvements or additional privacy controls that enhance your experience.
