How long does a phone update take typically ranges from a few minutes to over an hour, depending on the update size, your device model, Wi-Fi speed, battery level, and whether the phone is downloading and installing the update or just completing the installation. Official sources do not give one fixed time for all phones, so the actual duration depends on these specific conditions.
Factors that affect update duration
Several verified factors determine how long a phone update takes. The size of the update is a primary factor, major operating system updates with new features take longer than minor bug-fix patches. Your device model also matters; newer phones with faster processors typically install updates more quickly than older models. Wi-Fi speed directly impacts download time, and a stable, fast connection reduces the overall duration. Battery level is another factor, if your phone has low power, the update may pause or take longer. Whether the phone needs to download the update first or has already downloaded it and is only installing changes the total time significantly. Manufacturer and carrier policies and procedures can impact update duration, with some having more streamlined processes than others. User settings like enabling automatic updates can cause the update to occur in the background over an extended period, while manual initiation may complete more quickly.
How to update your iPhone
Apple documents the iPhone update path clearly. To update your iPhone, follow these steps:
- Open Settings.
- Tap General.
- Tap Software Update.
- If an update is shown, tap Download and Install, then follow the onscreen instructions.
The Software Update screen displays the currently installed iOS version and whether an update is available. For automatic updating, go to Settings > General > Software Update > Automatic Updates and turn on one of the listed options.
If you prefer to update using a computer, the method depends on your system. On a Mac with macOS 10.15 or later, open Finder, select your iPhone in the sidebar, click General, then Check for Update, then Download and Update. On macOS 10.14 or earlier, or on a Windows PC, open iTunes, select the iPhone button near the top left, click Summary, then Check for Update, then Update.
Checklist before you start an update
Apple recommends three verified steps before updating your iPhone:
- Back up your device to protect your data in case something goes wrong.
- Plug it into power so the update does not stop due to a low battery.
- Connect to Wi-Fi to ensure a stable, fast download and avoid using mobile data.
These steps apply whether you are updating directly on the iPhone or using automatic updates. Also, confirm that your device is compatible with the latest iOS version if the update will not install. Update apps prior to system update to minimize compatibility issues with the new OS. Restart your phone before updating to resolve temporary software glitches that may slow the process. Clear up storage space before starting the update, as updates require significant space to download and install. Some manufacturers provide specific firmware update tools that can streamline and optimize the update process.
Supported iPhone models
Apple’s current iOS 26 support page lists compatibility for iPhone 11 and later, plus iPhone SE (2nd generation and later). If your iPhone or iPad will not update, Apple advises checking whether the device model is on the compatible-device list. This ensures you are not trying to install an update that your hardware cannot run.
