iPhone Very Slow After Update: How to Fix It?

If your iPhone is very slow after a recent update, know that you are not alone. Often, after updating the operating system, especially with models from the iPhone X to the latest iPhone 17 Pro Max, users notice a significant decrease in the phone's performance. This slowness can hinder your daily experience and cause frustration, but fortunately, there are various solutions you can apply to restore the smoothness of your device.

At iServices, we understand the importance of a fast and efficient iPhone. Updates are essential to improve security and functionality, but they sometimes bring temporary performance issues with them. In this article, we explore the most common causes for your iPhone slowing down after an update, present practical solutions, and indicate when you should seek professional help from us.

Causes of a very slow iPhone after an update

Background processes after the update

After an iOS update, the system performs various tasks in the background, such as indexing files, optimizing photos, and updating applications. These tasks consume CPU resources and storage space, which can temporarily make the iPhone slower.

Insufficient storage space

When an iPhone's storage space is nearly full, the operating system struggles to manage temporary files and caches, which can result in lower performance. After an update, this problem may become even more apparent because the system needs space to function correctly.

Outdated or incompatible applications

Some applications may not be optimized for the new version of iOS and can cause slowness or even crashes on the phone. This happens especially with apps that have not been updated for the latest versions of the operating system.

Software problems or bugs in the update

In some cases, the update itself may contain bugs or errors that affect performance. These issues can be resolved via patches or by reinstalling the operating system.

Step-by-step solutions

Wait for background processes to finish

• Avoid intensive use of the phone after the update.
• Keep the device connected to a power source and Wi-Fi.
• Wait a few hours for the system to finish indexing and optimizing files.

Free up storage space

• Go to "Settings" > "General" > "iPhone Storage".
• See which applications take up the most space and delete the apps you don't use.
• Delete photos, videos, or files you no longer need, preferably after creating a backup.
• Clear application caches if possible.

Update applications

• Open the App Store.
• Tap your profile in the top right corner.
• Scroll down to "Available Updates".
• Update all applications to ensure compatibility with the new iOS version.

Restore iPhone via iTunes or iCloud

• Back up your iPhone via iCloud or iTunes so you don't lose data.
• Connect the iPhone to the computer and open iTunes (or Finder on recent macOS versions).
• Choose "Restore iPhone" to reinstall the operating system.
• After completion, restore the backup to get your data back.

Reset network settings or system settings

• Go to "Settings" > "General" > "Transfer or Reset iPhone".
• Select "Reset Network Settings" to fix Wi-Fi or mobile data issues.
• If the problem persists, you can choose "Reset All Settings" (this does not delete personal data, but resets system settings to factory defaults).

How long can the iPhone stay slow after an update?

Normally, the slowness after an update only lasts a few hours while the system performs optimization tasks. If the problem persists for longer than 24 to 48 hours, there is likely another underlying cause that needs to be investigated.

Can I lose data by restoring the iPhone to fix slowness?

If you create a backup before restoring, you will not lose data. iServices always recommends making a full backup in iCloud or on your computer before any restoration procedure to ensure the safety of your files, contacts, and settings.

Why is my iPhone X getting slower due to recent updates?

Older models such as the iPhone X can feel the impact of updates more strongly due to less powerful hardware compared to more recent models. The operating system may require more resources, which slows down the equipment. Keeping iOS up to date and deleting heavy applications can help improve performance.
