Receive a sudden pop-up on your iPhone prompting you to update your software?

Do you know what’s in store for you after you decide to update your iPhone? It’s time to learn about this.

Earlier this week, I saw an update notification for iOS 15. As I am addicted to testing new technologies and innovations, I upgraded my iPhone from 14.8 to iOS 15.

The results haunted me. My voice memos in iPhone 11 stopped working and when I tried to open it black screen appeared. You just can’t throw away your iPhone in such a situation? Can you?

But the good thing is that I managed to solve the problem. Now I'm going to share with you a few tips about iPhone software updates with my real experience.

If you’re interested in updating your iPhone to the latest iOS version, then this article is going to be very exciting for you!

Part 1 Why Do We Need to Update iPhone Software?

Don’t you think that updating iPhone software is a better experience in most cases?

Especially when you are enthusiastic about enjoying new features proposed by the latest version.

In addition, these updates fix some system loopholes and are essential to maintain your device’s security.In case you are unaware of the fact, let me reveal that Apple’s iOS 15 update has arrived on Sept 20.

This update has brought some extremely brilliant features such as FaceTime-calling your friends on Android, iMessage sharing features, Apple Map updates, Focus Mode for managing notifications, and the latest wallet update allows you to store your driver's license on your iPhone.

However, there are some rare instances where updating can be troublesome. Hence, you must know the dark side as well. Consider the following points that I’ve compiled for you before updating your software.

Make sure your iPhone is compatible with the iOS 15:

The actual reason behind updating your iPhone software is to enjoy advanced features, improve your phone’s performance, and enhance your device’s security.

But sometimes this could be a bad experience for you. Wondering when?

Well! When your older device doesn’t support the new operating system. As I mentioned above, this is exactly what happened when I updated my device. Ah! I juggled a lot with my weirdly behaving iPhone.

Whatever the situation may be, make sure to visit Apple’s website before updating your device to see which version of iOS is compatible with your iPhone.

Note that update cannot be downgraded

Are you taking the iPhone update software issue lightly?

Beware, this matter is serious as Apple said, “Note that after a software update is installed for iOS, iPadOS, tvOS, and watchOS, it cannot be downgraded to the previous version.”

This means you need to think carefully before you make the decision to update. Once the decision is taken, you can no longer revert to the previous system. Furthermore, if the latest version is not compatible with your iPhone, be ready to face the consequences.

The story of the dark side doesn’t end here. Let’s have a look at some other disadvantages of updating your device.

Other disadvantages of updating latest iOS:

notifications not working in ios 15
  1. Bloated and cluttered UI with many new features you don't want:
  2. If you ask me, I really don’t desire to have the features introduced in newer updates, especially since iOS 11.

    The reason is my observation, according to which the interface has gotten very bloated and cluttered over the years.

  3. Slow down device:
    • Generally speaking, updating your old device may slow it down as well as disrupt its performance. For example, On iOS 7, iOS 10, and iOS 9, respectively, the iPhone 4, iPhone 5, and iPhone 4S perform slowly.
    • People have even reported to me that after updating their iPhone 4S to iOS 9, the device was practically unusable because of the systemwide lag they experienced just after the update.

After reading the above disadvantages you might have carefully weighed the potential trouble caused when you update your device. Ready to know more?

Great! For the process to go smoothly, you should take certain steps before upgrading to iOS 15. Let’s explore these steps in the next section.

Part 2 How to Update iPhone Software?

Generally, if you receive a message that an update is available, then:

  • Click Install Now if you wish to start instantly.
  • You can tap Later and choose Install Tonight or Remind Me Later to install later.
  • If you select Install Tonight, you'll be prompted to plug your device into power overnight,write and your device will be updated automatically.
  • Alternatively, you can use the Settings app on your iPhone to update.

However, I have come across many users who face difficulty when updating their devices because they have not prepared their devices for the update.

What exactly does preparing your device mean? Well! I have done some hard work for you and formulated a list of these preparations. Let’s reveal the list together.

Preparation Before Updating iPhone Software:

  • Make it a habit to back up your iPhone before installing an iOS update (or updating an iPhone with irreplaceable data).
  • The easiest way to do this is through iCloud or iTunes.
  • Check that your backup has been completed successfully (in iCloud or iTunes), ensure that all of your photos are in iCloud.com if you use iCloud.
  • Connect your computer to a different Wi-Fi or Ethernet network if your computer is using a Personal Hotspot.
  • When updating your iPhone, keep it fully charged, since the update may take a while.
  • The screen passcode is mandatory.
  • A normal rule of thumb is to leave at least 10% of your iOS device's capacity free. Make sure you have this much storage free before you proceed.

Have you done all the above preparations? Good work! Now go ahead and start updating your iPhone. The first method, which I will share with you, is through the Settings app. Let’s learn how it works.

Method 1 Update iPhone Software Wirelessly Via Settings

According to my observation, I have noticed that many iPhone users update the device directly without connecting it to a computer. The process is what Apple calls wireless installation.

There are certain things you require before you start updating your iPhone via Settings app. This method also has some disadvantages. Let’s have a look at them.


  • You will need a USB cable to plug your iPhone into power.
  • A Wifi Network is required.
  • Ensure to have enough space as I mentioned before.


One of these reasons might prevent you from updating your iPhone, wirelessly or over the air.

  • Unavailability of enough storage space on your device
  • Updates take a long time to download
  • Error reaching update server
  • The update does not complete


  1. Make sure the Wi-Fi is turned on and then plug the device into a power source.
  2. From Settings, navigate to General, and then click on Software Update.
  3. Whenever you see two software update options, select the one you want to install.
  4. Click Install Now. Alternatively, you can click Download and Install to download a new update, enter the passcode, then click Install Now.

This was all about updating your device through the Settings app.

However, you might have realized that it is not a foolproof method as I already stated the reasons why this method could fail. This takes us to another method in which we can use iTunes to update our device.

Method 2: Update iPhone Software Via iTunes/Finder

The other way round is to get your device updated via iTunes or Finder. Apple also recommends updating your iPhone via iTunes or Finder and guides us along the way. Follow these steps to get going with the process.


  • The process is lengthy and the success rate is low.
  • Apple's iTunes software interface doesn't feel good to use and it frequently fails to connect.
  • There is a possibility that the method may fail to work, causing the whole process to begin from scratch.


The following steps will help you download the latest version of iOS or iPadOS using your computer:

  1. Open Finder or iTunes on your computer.
  2. Connect your device to your computer.
  3. Locate your iPhone on your computer. You will find it on the left under "Locations" in Finder; click it. In iTunes, you will find the iPhone icon near the top of the toolbar; click it.
  4. Trust the device if prompted.
  5. Choose General (in Finder) or Settings > Summary (in iTunes) from the window that appears with information about your iPhone. Tap "Check for Updates."
  6. When an update is available, click "Download," and thereafter, click "Update".
  7. If prompted, enter your passcode. When the update has been installed, you will be ready to use the software.

If you’ve successfully accomplished the goal of updating your iPhone, Bravo! You finally did it.

But what if the update wasn’t finished successfully? Was it interrupted or did some other thing go wrong?

Well! No need to get disappointed because I have compiled a few problems that you might encounter during the process of the iPhone software update. To your relief, I’ll be giving the solutions as well. Let’s get into the details.

Part 3 How to Fix Update Failure?

Method 1 Remove the update If you can't install the latest version

Is your iPhone operating normally without any screen issues even if you tried but couldn't install the latest version of iOS or iPadOS?

In this case, you must try downloading the update again follow the steps below:


  1. Navigate to Settings > General > [Device name] Storage.
  2. Find the Update option in the list of apps.
  3. Click Update, then tap Delete Update.
  4. Download the latest update by going to Settings > General > Software Update.
delete update and reinstall

It would be great if all goes well. But if you are unable to fix the update failure with the steps mentioned above or your device is behaving abnormally like the screen is stuck on the Apple logo etc, you will need to use recovery mode to fix the problem. Here is how it works.

Method 2 Use Recovery Mode to Fix Software Update Problem

Has your iPhone started behaving weirdly after you made an attempt to update it? Using recovery mode is necessary if the following issues appear on your iPhone after an update:

  • Your computer doesn't recognize your device.
  • It tells you that it is in recovery mode.
  • If your screen has been stuck on the Apple logo for several minutes with no progress bar.

Note: Find out what to do if the progress bar appears on your screen for several minutes.

Though this method is recommended by Apple, it has some drawbacks which are mentioned below.


  • The process is time-consuming and has a low success rate.
  • The interface of the iTunes operating system does not feel pleasant to use and often fails to connect.
  • This method will wipe out all the data in your iPhone, which may result in some deleted data that was not backed up in time.

Steps for using Recovery Mode:

  1. Keep your Finder or iTunes up-to-date.
  2. Open Finder or iTunes. (Close iTunes or Finder if it's already open, then reopen it.)
  3. Put your iPhone into recovery mode.

  4. restore ios
  5. Locate your iPhone on your computer. If you are given the option of restoring or updating, select “Update”.
  6. Once the update or restoration is complete, set up your device.

As I said before, this method does not have a high success rate. Why am I so sure? Because I have experienced it first hand.

A few months back, I updated my iPhone because I wanted to test the latest system. After charging my iPhone during the night, I connected it to the internet, but it hadn't updated when I woke up the following morning.

All I could see was a stuck screen having the Apple logo with no progress bar. I then used recovery mode but it didn’t work either.

I had to search for other solutions and I ended up exploring “Mobitrix Perfix.” This tool solved my problem instantly and saved me from struggling any further. Let me reveal the details of this magical tool to you.
