iOS 27 Guide for Beginners: Set Up, Secure and Use Your iPhone

iOS 27 is the current iPhone software as of September 14, 2026, the day Apple started rolling it out as a free update. It runs on every iPhone that could run iOS 26, from the iPhone 11 and the second-generation iPhone SE up to the new iPhone 18 Pro. Its headline feature, the rebuilt Siri AI assistant, is a different story: that needs an iPhone 15 Pro, an iPhone Air, an iPhone Duo or any iPhone 16 or later.

That split matters more than the version number. An iPhone 12 and an iPhone 17 Pro can both say iOS 27 in Settings, yet only one of them gets Apple Intelligence. This guide covers what a new or returning iPhone owner actually has to deal with: the Apple Account, Face ID and the passcode, updates, the privacy and Screen Time settings worth changing, the App Store, iCloud storage, Find My, the anti-theft and anti-spyware tools, accessibility and Apple Intelligence. Most of the steps also apply if your iPhone is still on iOS 26.

Updated, September 14, 2026: Rewritten from a 2020 iOS 13 tips post into a current beginner’s guide covering the iOS 27 release, supported iPhones, Apple Intelligence requirements and today’s security settings. Outdated iOS 13 videos and screenshots were removed.

What is the latest iOS version? iOS 27 explained

Apple released iOS 27 on September 14, 2026, together with iPadOS 27, macOS 27, watchOS 27, visionOS 27 and tvOS 27, and its release announcement refers to the group as its “2027 software releases.” The update was first shown at WWDC26 on June 8, 2026.

The numbering looks strange if you last owned an iPhone a few years ago. At WWDC25 in June 2025, Apple dropped sequential version numbers for year-based names across all of its platforms, so iOS 18 was followed by iOS 26 rather than iOS 19. iOS 26 shipped on September 15, 2025 with the Liquid Glass redesign. The number points to the year ahead, which is why a release that arrives in September 2026 is called iOS 27. It has nothing to do with the iPhone model number: an iPhone 11 runs iOS 27 too.

If your phone has not offered the update yet, iOS 26.6.2, released September 8, 2026, was the newest iOS 26 build on Apple’s security releases page. That page carries two warnings worth reading before you tap Install: once an iOS update is installed it cannot be downgraded to the previous version, and models dropped from current iOS only get occasional fixes (the iPhone XS, XS Max and XR received iOS 18.7.10 in August 2026).

Which iPhones support iOS 27?

Apple’s iOS 27 page lists exactly the same models that ran iOS 26. The real dividing line is Apple Intelligence, and a few extras such as customizable Siri voices are limited to the newest, higher-memory models.

iPhone models	Runs iOS 27	Apple Intelligence and Siri AI
iPhone 18 Pro, 18 Pro Max, iPhone Duo, iPhone 17 Pro, 17 Pro Max, iPhone Air	Yes	Yes, including customizable Siri voices
All iPhone 16 models, iPhone 17, iPhone 17e, iPhone 15 Pro and 15 Pro Max	Yes	Yes
iPhone 11, 12, 13 and 14 series, iPhone 15 and 15 Plus, iPhone SE (2nd and 3rd generation)	Yes	No
iPhone XS, XS Max, XR and older	No	No

To check your model and current software, open Settings, tap General, then tap About. If you are shopping for a used iPhone mainly for Siri AI, the iPhone 15 Pro is the oldest model Apple supports; an iPhone 14 or a standard iPhone 15 will run iOS 27 but is not on Apple’s Apple Intelligence list. For how the lineup got to this point, see TechEngage’s history of every iPhone generation.

How to set up a new iPhone on iOS 27

Press and hold the side button until the Apple logo appears, then follow the Hello screen. Apple’s setup guide shows two early choices that beginners often skip past: a text and icon size picker (Default, Medium or Large) and, on the Hello screen itself, VoiceOver or Zoom for anyone who is blind or has low vision. You need Wi-Fi or a cellular connection to activate the phone.

Moving from another iPhone with Quick Start

If your old iPhone or iPad runs iOS 11, iPadOS 13 or later, Quick Start copies your settings and data when you hold the two devices close together. It ties up both devices for several minutes. You can download everything from iCloud, which lets you use the new phone while apps and data arrive in the background, or transfer directly, which means waiting until the copy finishes with both phones plugged in. A direct transfer is the safer pick when your last iCloud backup is old or your iCloud storage is full.

Moving from Android

Apple’s Move to iOS process carries over contacts, message history, photos and videos, calendars, mail accounts, WhatsApp messages and media, and some free apps that exist on both stores. Android phones on a compatible version of Android 17 can transfer without the Move to iOS app, and a USB-C cable between the phones speeds things up. The catch: it only works during iPhone setup. If you already finished setup, you have to erase the iPhone and start again, or move content by hand. TechEngage’s new smartphone setup checklist covers the steps that apply to any new phone.

Create or sign in with your Apple Account

Apple ID is now called Apple Account, and existing users sign in with the same email address or phone number and password. During setup you can create a free Apple Account by tapping the forgot password or no account option; if you do not have an email address, Apple offers a free iCloud address. The account powers iCloud, the App Store, Find My and Apple Pay, so use an email you will still control in five years.

Two-factor authentication is the default for most accounts. Signing in on a new device requires your password plus a six-digit code that appears on your trusted devices or arrives at your trusted phone number, and services such as Apple Pay and Sign in with Apple require it. If you want stronger protection still, Apple Accounts also accept physical security keys.

Face ID, Touch ID and a stronger passcode

To set up Face ID, go to Settings, tap Face ID & Passcode, tap Set Up Face ID and move your head in a circle for two scans. Apple says it works best with the iPhone about 10 to 20 inches from your face, and iPhone 12 or later can recognize you while you wear a mask. The iPhone SE models use Touch ID on the Home button instead, under Settings, Touch ID & Passcode.

Face ID never fully replaces the device passcode. The iPhone asks for it after a restart, before a software update, before erasing the device and before passcode settings change. The default is six digits; Passcode Options lets you switch to a custom numeric or alphanumeric code. Since Face ID handles most day-to-day sign-ins, a longer passcode costs you very little, and it is the one secret a thief who watched you type it could use against you.

How to update to iOS 27

Apple’s update instructions are short:

1. Back up the iPhone to iCloud or a computer.
2. Plug it into power and connect to Wi-Fi.
3. Open Settings, tap General, then tap Software Update.
4. Tap Download and Install and follow the prompts.

If the iPhone asks to temporarily remove apps to make room, tapping Continue is fine: those apps reinstall automatically after the update. A VPN or proxy can stop the phone reaching Apple’s update servers, so turn it off if the download stalls. Under Software Update, Automatic Updates lets the phone install new versions on its own, which is what Apple recommends.

Should you wait? Siri AI is labeled a beta, and a big x.0 release can trip up niche apps. Waiting a few days for early bug-fix updates is reasonable if a work or banking app has not confirmed support. Turning updates off for months is not, because security fixes arrive through the same updates. The same trade-off explains why jailbreaking has always meant staying on specific older builds, a story told in TechEngage’s history of iOS jailbreaking.

iOS 27 settings to change first

Privacy: stop apps from tracking you

Since iOS 14.5, apps must ask before tracking you across other companies’ apps and websites. Choosing Ask App Not to Track blocks the app from the system advertising identifier, and Apple’s App Tracking Transparency page confirms the app still works fully either way. To review earlier answers, go to Settings, Privacy & Security, Tracking. Turning off Allow Apps to Request to Track denies every future request without a prompt, which is the simplest choice for most people.

Screen Time and parental controls

Screen Time, in Settings, shows how much time goes into each app and website. For children it does much more: parents can manage a child’s Screen Time from their own iPhone once the child’s Apple Account is in a Family Sharing group, schedule daily app limits and block content that is not age appropriate. Content and Privacy Restrictions control purchases, downloads and privacy settings, and depending on the country and the child’s age, some protections are switched on by default.

iOS 27 adds the biggest set of child safety changes in years: a simpler child account setup with a recommended set of essential apps, Ask to Browse (parents approve new websites in Safari), Communication Safety that now also blocks gore and violent content in shared images, videos and live FaceTime calls, and age-based Time Allowances for Social Media, Entertainment and Games. One practical snag: every device in the Family Sharing group must be updated to the 27 releases before the new Screen Time works.

Focus and notifications

A Focus such as Work, Personal or Sleep silences everything except the people and apps you allow. In Settings, tap Focus, pick one, choose allowed People and Apps, then use Add Schedule to switch it on at a set time, at a location or when you open a certain app. On Apple Intelligence iPhones, the Reduce Interruptions Focus tries to let only important alerts through.

For everything else, the notification settings are worth ten minutes. Swipe left on any notification to change alerts for that app, and go to Settings, Notifications, Show Previews to decide whether message contents appear on the Lock Screen. Limiting previews keeps message text off the Lock Screen when the phone is lying face up on a table.

Dark Mode, Liquid Glass and the Home Screen

Go to Settings, Display & Brightness and pick Dark, or Automatic to switch on a schedule; Dark Mode can also be toggled by touching and holding the brightness slider in Control Center. iOS 27 adds a slider in Settings that adjusts the Liquid Glass look anywhere from ultraclear to fully tinted, which helps if the translucent iOS 26 design made menus hard to read.

You do not need every app on the Home Screen. Swipe left past the last page to reach the App Library, which sorts apps into categories automatically. Touch and hold an app, then tap Remove App and Remove from Home Screen, to hide it without deleting it. Touch and hold an empty area and tap the dots near the bottom to hide or reorder whole pages.

App Store basics on iOS 27

Open the App Store and browse the Today, Games, Apps and Arcade tabs, or tap Search. A Get button means the app is free, a price means it is paid, and Open means you already have it. To download an app, tap Get or the price and double-click the side button to confirm with Face ID. Free apps can still sell in-app purchases and subscriptions, so check the listing for them before you install a game for a child.

Each listing has an App Privacy section showing what data an app may collect, what is linked to you and what is used to track you. Apple notes that this privacy information is self-reported by the developer, so treat it as a disclosure, not an audit.

iCloud storage and backups

Every Apple Account includes 5 GB of free iCloud storage. iCloud+ plans add 50 GB, 200 GB, 2 TB, 6 TB or 12 TB, plus Private Relay, Hide My Email and custom email domains. In the U.S. they cost $0.99, $2.99, $9.99, $29.99 and $59.99 a month, and any plan can be shared with up to five family members. Five gigabytes fills quickly once a phone backup and a photo library share it, so most people either pay for a plan or accept that iCloud Backup will stop. Apple One bundles can be cheaper if you already pay for Apple Music or Apple TV.

To turn on iCloud Backup, open Settings, tap your name, tap iCloud, tap iCloud Backup and switch on Back Up This iPhone. Backups run automatically when the phone is on power, on Wi-Fi and locked, which in practice means overnight. Back Up Now forces one before an update. If you would rather not pay for storage, you can copy photos to an external drive to keep the library out of iCloud.

Advanced Data Protection is an optional setting that extends end-to-end encryption to most iCloud data, including backups, Photos and Notes, so not even Apple can read it. The trade-off is recovery: Apple no longer holds the keys, so you must set up a recovery contact or a 28-character recovery key first. It suits people who will actually store that key safely; anyone who forgets passwords regularly should think twice.

Find My: turn it on before you need it

Open Settings, tap your name, tap Find My, then Find My iPhone, and make sure all three switches are on: Find My iPhone, Find My network (which lets the phone be located while offline) and Send Last Location (which reports its position when the battery runs low). Apple’s Find My setup page covers AirPods, Apple Watch and AirTags too. Find My has to be on before a phone goes missing, and Stolen Device Protection depends on it. If the worst happens, follow TechEngage’s lost phone recovery steps.

iPhone security features in iOS 27

Stolen Device Protection

The most useful security switch for ordinary users targets a common crime: someone watches you enter your passcode, then steals the phone. With Stolen Device Protection on, and the iPhone away from familiar places such as home or work, viewing saved passwords or cards requires Face ID or Touch ID with no passcode fallback, and changing your Apple Account password requires a one-hour security delay followed by a second biometric check. It needs two-factor authentication, a passcode, Face ID or Touch ID, Significant Locations and Find My. It may already be on; check under Settings, Face ID & Passcode, Stolen Device Protection, and turn it off before you sell or trade in the phone.

Lockdown Mode

Lockdown Mode is an extreme option built for the very few people who, because of who they are or what they do, might be personally targeted by mercenary spyware. It blocks most message attachments and link previews, blocks FaceTime calls from people you have not called in the past 30 days, and disables some complex web technologies, so websites may break. Most people should leave it off. It lives under Settings, Privacy & Security, Lockdown Mode, and turning it on restarts the phone.

Safety Check

Safety Check, under Settings, Privacy & Security, is designed for people leaving an abusive relationship or worried that someone has access to their phone. Emergency Reset immediately stops sharing your location and data with all people and apps, while Manage Sharing & Access lets you review who sees what, one person or app at a time. A Quick Exit button closes Settings instantly if someone walks in.

Accessibility features on iOS 26 and iOS 27

Accessibility settings are not only for people with disabilities; many are simply better ways to use a phone. Apple’s accessibility support hub covers VoiceOver, Magnifier, AssistiveTouch (an on-screen button that replaces physical gestures), Voice Control, Switch Control and Personal Voice with Live Speech. All of them sit in Settings, Accessibility, and you can assign favorites to the Accessibility Shortcut.

Guided Access is the one every parent should know. Turn it on in Settings, Accessibility, Guided Access, set a passcode, then open an app and triple-click the side button to lock the iPhone to that app, with optional time limits and parts of the screen disabled. Hand the phone over and a child cannot wander into your email.

iOS 27 adds richer VoiceOver image descriptions, Action button integration so VoiceOver users can ask about what the camera sees, and automatically generated subtitles for videos. Apple first detailed these in its May 2026 accessibility announcement, which also promised a Voice Control that understands natural descriptions such as the purple folder instead of exact button labels. Many of these run on Apple Intelligence, so the most advanced versions depend on a supported iPhone.

Apple Intelligence and Siri AI on iOS 27: requirements

Apple’s Apple Intelligence requirements are specific: an iPhone 15 Pro model or an iPhone 16 model or later, 7 GB of free storage, and the device language and Siri language set to the same supported language. Turn it on in Settings, Apple Intelligence & Siri; the on-device models then download, faster on Wi-Fi and power. It supports 16 languages, including English, French, German, Spanish, Portuguese, Japanese, Korean, Vietnamese and both simplified and traditional Chinese.

Siri AI, the new conversational Siri with its own app, arrives with more conditions than the rest of iOS 27. According to Apple’s release announcement linked above, it starts as a beta in English, with French, Japanese, Korean, Portuguese and Spanish due in October. It is not available to users under 13, it is not available in China while Apple works through regulatory requirements, and server-based features such as Siri AI, Image Playground and the photo editing tools have daily usage limits. Apple also says expanded access to those features will cost a fee in the future, without naming a price.

iPhone owners in the European Union are left out for now. Apple says the Digital Markets Act prevents it from shipping Siri AI on iPhone and iPad in the EU, gives no timeline, and offers it there only on Mac and Apple Vision Pro.

Who should care? If you mostly call, text, browse and take photos, an iPhone 13 or 14 on iOS 27 still gets the security features, parental controls, performance improvements and design refinements covered above. Apple Intelligence becomes a reason to upgrade only if you would actually use a chat-style assistant, AI photo edits or writing tools every day, and only if your language and region are supported.
