Moreover, the latest update focused on privacy enhancement while entirely redesigning Safari, Weather, and Maps. However, although the installation of iOS 15 is straightforward, many people have been facing problems with the same. Here are the solutions for ‘how long does ios 15 take to install’.

How to Install iOS 15?

To begin with, you need to make sure you have an iPhone SE (1st generation) or newer or an iPhone 6s or newer. As those iPhones were released in 2016 and 2015, the vast majority of consumers should be able to obtain the upgrade. What you should do is as follows:

  • Connect your iPhone to Wi-Fi and a power source if it is compatible.
  • Go to the Settings menu.
  • Open General settings
  • Open the Software Update window.
  • Select Download and Install from the drop-down menu.

How Long Does It Take to Update to The Latest iOS?

Installing a new iOS version on your phone takes approximately 30 minutes. However, the exact time depends on your internet speed and device storage.

Apple’s iOS 15.4.1 update is a minor feature improvement, but it is expected to take time to install on your iPhone.

Apple has released a new version of iOS 15.4.1, and the software provides a small number of modifications to iPhone users. Even though the update does not include any new features, it does have some critical bug fixes.

The shortest list of changes and the smallest download size are available to those upgrading their iPhone from iOS 15.4 to iOS 15.4.1, respectively. To give you an idea of the size of the upgrade, the iOS 15.4.1 update for iPhone 12 Pro customers who are upgrading from iOS 15.4 is approximately 300MB.

You may notice that your iOS 15.4.1 download is more significant if you’re upgrading from an older version of iOS. This is because the improvements from the update(s) you skipped are baked into the new version of iOS.

The iOS 15.4.1 update is available for download today. While some of you may want to wait until later, most of you should install the software immediately or as soon as possible.

Why is iOS 15 Downloading So Slow?

Whether you haven’t backed up your data in a while or are unfamiliar with the changes in iOS 15.4.1, the pre-installation procedure may take a little longer.

Ensure that your iPhone is linked to a stable WiFi network and that cellular data is not turned on before an iOS software update. You must charge the battery or connect the USB wire while using the device.

So, if you find that the process of updating your iPhone is taking an excessive amount of time, one of the listed below may be the reason:

iPhone Model

The iPhone model may also impact the size of the iOS 14/15 download file for iOS 14. Apple has created an iOS build specifically for older iPhone models to make the most of their resources. To be eligible, ensure you have an iPhone SE (1st generation) or newer or an iPhone 6s or newer.

Apple Server

Because the iOS 15 beta is still in its early stages, the time you attempt to update to the beta version is equally critical. During peak hours, the enormous number of people upgrading to the new version of iOS can cause Apple’s servers to become overburdened.

When most people are still asleep in the morning, it appears to be the optimal time to upload because the automatic updates have ample time to complete.

Region (Size of the Update)

The time it takes to download and install the iOS 14 or 15 betas will vary greatly depending on the user’s geographic location. In some places, you won’t be able to access all of Apple’s services due to regulatory restrictions.

While some iPhone owners will be required to download 2,83GB of iOS 14/15, most will be able to download 4,79 GB. To avoid including services unavailable in their location, they have been excluded from the final output.

Available Storage Space

If your iPhone’s storage is nearing capacity, the iOS 14/15 upgrade will seek to offload apps to make some free space. As a result, iOS 14/15 will take significantly longer to complete.

Internet Connectivity

The speed with which your iPhone’s Internet connection is probably the most crucial aspect in determining how long it will take to update to iOS 14/15 on your iPhone.

When updating to iOS 14/15, we recommend using a WiFi connection to complete the process. If you do not have a stable Internet connection, it will take longer to download the iOS 14/15 software upgrade.

5 ways to Speed Up iOS 15 Download? 

Here are the five ways to speed up the iOS 15 downloads:

  1. Force Restart Your Device
  2. Check Your Network Connection
  3. Check Apple Server Status
  4. Check Your iPhone Storage Space
  5. Reset Network Settings

1. Force Restart Your Device

When your iPhone is stuck in the download process, it is possible that simply restarting the device would solve the problem.

Follow these procedures whether you want to restart an iPhone 11, iPhone 12, or iPhone 13 model (not just the X, XS, or XR), and you’ll be OK.

  • Using the side button, press and hold it for a few seconds after pressing and releasing the volume keys one at a time. 
  • Press and hold the button for 30 seconds when you see the Apple logo.

2. Check Your Network Connection

With an unstable internet connection, the iOS 14/15 upgrade may become unresponsive. A solid and reliable network connection is required for the update process to succeed.

  • Restore the default configurations of your router.
  • If you’re using iOS or iPadOS 15 or later, go to the Reset option in General Settings. 
Go to the Reset option in the general settings on your iPhone device.
  • Now click on the Reset Network Settings option to clear your network settings. 
Go to the Reset Network Settings in the Reset option on the iPhone.
  • If you wish to reset all of your network settings in iOS or iPadOS 14, go to Settings > General > Reset > Reset Network Settings in your device’s settings menu.

3. Check Apple Server Status

If none of those options mentioned above work, it’s conceivable that you’ll have to look into difficulties with the Apple server. Services, shops, and iCloud may be examined to verify whether they are available and operational.

Determining whether Apple Servers are down or experiencing service issues is straightforward with this application.

  • If you go to the following URL, it will direct you to the Apple Support system’s status page: https://www.apple.com/support/systemstatus/.
  • If you are having difficulties installing apps, logging into iCloud, or accessing Apple Maps, this is the first place you should look to determine whether or not Apple is to blame for the problem. 
  • If this is the case, the only thing that you can do is patiently await events, and Apple has agreed to take care of the situation. 
  • If the situation persists, you should begin troubleshooting.

4. Check Your iPhone Storage Space

Your issues could also be caused by a shortage of available storage space on your iPhone or iPad, which would prevent the download of the iOS 14/15 upgrade from continuing.

Alternatively, if the download takes excessive time, check your device storage to see if there is sufficient space for the iOS 14/15 upgrade.

  • Navigate to [Device] Storage in the Settings menu and confirm your selection. 
Navigate to Device Storage to free up the storage space
  • Following a list of storage-optimization recommendations, you will be able to examine the programs that have been installed as well as the amount of storage they consume.

5. Reset Network Settings

Those mentioned above were some of the most effective methods for restoring functionality to your iOS device when it has become stuck or frozen during the update to iOS 14. I hope you have found this post to be of assistance.

  • If you’re using iOS or iPadOS 15 or later, go to Settings > Reset [Device] > Reset Network Settings to clear your network settings. 
Go to settings to reset the settings
  • If you wish to reset all of your network settings in iOS or iPadOS 14, go to Settings > General > Reset > Reset Network Settings in your device’s settings menu.


Hundreds of tweaks and changes have been made to apps with iOS 15 updates. This includes new user-created tags, mentions, an Activity view in the Notes app, Trends in the Health app, and many more.

Also, Apple has introduced contact photographs for people and larger icons for apps to stand out more.

To enjoy these new features, you have to install the update, which might take longer than expected if yours is not the proper iPhone model or you are in any particular region.

However, there are many ways, from restarting the device to checking the Apple server, by which you can solve this issue.
