Apple devices often maintain relevance over extended periods thanks to meticulous hardware design and long-term software support. For example, the iPhone 11, originally released in 2019, can still run the latest version of iOS more than seven years later. Checking which software version your device currently runs requires just a few quick taps through the system settings.
Key takeaways
- Navigate to Settings, then General, and About to check your current iOS version.
- Manual updates require at least 20 percent battery charge and a stable Wi-Fi connection.
- Users can update their iPhones via a Mac, Windows PC, or the Apple Devices app.
- Backing up via iCloud or a computer is recommended before installing new software.
Checking your current iOS version and updating manually
If you want to check the operating system version on your iPhone, open the Settings app and navigate to General, then About, and finally tap on iOS Version. Your device should notify you when a new software version becomes available, and the installation process takes only a few minutes once the download finishes.
To check for updates manually, head to Settings, select General, and then tap Software Update. This page displays your current software version along with a Download and Install button if an update is available. If a major software release is available, such as iOS 27, it appears in a separate Also Available section at the bottom of the screen. Once you download the update, tap Update Now, enter your passcode, and accept the terms and conditions. Your iPhone will reboot automatically to finish installing the update.
You can also configure your device to download and install updates automatically by tapping Automatic Updates and turning the Automatically Install toggle on. Your iPhone will handle software updates independently when connected to Wi-Fi and holding sufficient battery charge. For manual updates, your battery needs to maintain at least 20 percent charge.
Updating via a computer and managing backups
Update sizes vary significantly depending on the release type. Security updates and hotfixes may only measure a couple hundred megabytes, while major iOS upgrades span several gigabytes, making a fast Wi-Fi network essential. If your Wi-Fi connection is unreliable, you can update your iPhone using a computer with a cable. You may need to tap Trust on your iPhone screen if it is your first time connecting to that specific computer.
Mac users running macOS 10.15 or newer can open Finder, select the iPhone from the sidebar, click Check for Update in the General tab, and confirm by clicking Update. Windows users can install the Apple Devices app, while older Mac and Windows computers can still use iTunes. Apple recommends backing up your iPhone before installing software updates. On your device, open Settings, tap your name at the top, navigate to iCloud, select iCloud Backup, and tap Back Up Now. If you lack sufficient iCloud storage, you can back up your iPhone directly to a Mac or Windows PC using Finder, iTunes, or the Apple Devices app.
Performance improvements and new features
Recent software updates bring substantial performance benefits, particularly for older hardware models. While previous iterations like iOS 26 were demanding and buggy, iOS 27 prioritizes stability and features an optimized CPU scheduler capable of launching apps up to 30 percent faster according to Apple. Furthermore, Siri AI has arrived, allowing users with Apple Intelligence-powered iPhones to join the beta waitlist by navigating to Settings and Siri.
