Thinking about updating your iPhone software system, but worried it might take too long? How long does it take to update an iPhone? The time it takes to update an iPhone can vary depending on several factors. In this comprehensive guide, whether it's iOS 17 or iOS 18 that you're trying to update to, we'll show you the various aspects that affect the update duration and provide you with detailed insights to help you better understand the process.

Part 1. How Long Does It Take to Update iPhone to iOS 17/iOS 18?

The duration of the iOS 17 or the latest iOS 18 download process varies depending on several factors, including your device's hardware, available storage space, and the speed of your internet connection. On average, the installation should take between 30 to 40 minutes. Below is a breakdown of the timeframes you can expect during each stage:

Download Time: With a stable internet connection, the iOS 17 or iOS 18 beta should take 5 to 15 minutes to download. This timeframe can be extended if your connection speed is slower or if Apple's servers are experiencing high traffic.

Preparation and Installation: Once the download is complete, the actual installation, including the verification and preparation stages, should take 15 to 20 minutes. This process involves verifying the update package and installing the new firmware on your device.

Note

These times are estimates, and the process can be affected by various factors, which we will explore in the following sections.

Part 2. 5 Factors that Affect iPhone Update Duration

When Apple releases a new iOS update, it typically comes with enhancements, bug fixes, and new features. The update process involves downloading the update file, preparing the device, installing the update, and finalizing the setup. Each of these stages can take a different amount of time based on several factors:

1. Internet Connection Speed

The speed of your internet connection plays a crucial role in how quickly the update file is downloaded. A faster connection can significantly reduce the time required for this stage.

2. Update File Size

The size of the update file can vary. Major updates (e.g., iOS 17 to iOS 18) are usually larger and take longer to download and install compared to minor updates (e.g., iOS 18.1 to iOS 18.1.1).

3. Device Model and Age

Newer iPhone models typically have faster processors and more efficient hardware, which can speed up the update process. Older models may take longer to update due to slower processing speeds.

4. Available Storage Space

Sufficient storage space is essential for downloading and installing the update. If your device does not have enough storage to update iPhone or running low on storage, it may take longer to update or may not install at all as the system manages space.

5. Battery Level

Ensuring your iPhone has sufficient battery charge (preferably over 50%) or is connected to a power source is important. If the battery level is low, the update may be delayed or paused.

Part 3. Tips to Speed Up iPhone Update Process

Updating your iPhone can be a time-consuming task, especially when dealing with large updates like iOS 18. However, by following a few strategic steps, you can significantly speed up the process.

1 Optimize Your Internet Connection

A strong and stable internet connection is crucial for a swift update. If your Wi-Fi is slow or unstable, the download and installation of the update may take much longer than expected. You can improve your connection by moving closer to your router or resetting your network settings.

To reset network settings, go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.

This can often resolve connectivity issues and help speed up the update process.

2 Free Up Sufficient Storage

Ensure that your iPhone has enough free storage space for the update. iOS updates require a significant amount of storage, both for downloading the update file and for temporary storage during installation.

To check your available storage, go to Settings > General > iPhone Storage. If you’re running low on space, consider deleting unnecessary apps, photos, and videos to make room for the update.

3 Restart Your Device

Sometimes, a simple restart can resolve issues that cause the update process to slow down. Restarting your iPhone can clear out temporary system glitches that might be interfering with the update. To restart, turn off your device and then power it back on. This quick fix can often make a noticeable difference.

3 Monitor Apple’s Server Status

If your update is still taking an unusually long time, it might be due to high traffic on Apple’s servers, especially during peak hours. In such cases, try updating your iPhone during off-peak times, such as late at night or early in the morning. This can help you avoid server-related delays and speed up the update process.
