Why Is My iPhone Slow After iOS 17 Update? Here to Solve it

Jun 14, 2024 • Filed to: Mobile Repair Solutions • Proven solutions


Getting a new iOS update like iOS 17 sounds great, right? You expect new stuff and better security. But sometimes, after updating, your iPhone might start feeling slower.

When it comes to technology, updates are a mix of excitement and challenges. The new features are great but can also be demanding on your phone's resources. This can make your iPhone seem slower after an update, even though it got cool new features.

But guess what? There are several solutions to improve things. Let's figure out how to fix it and why your iPhone slows after update iOS 17.

What Makes Your iPhone Slow After Update iOS 17

Seriously, why is my iPhone so slow after iOS 17 update? If you encounter this issue, I know some possible causes of this issue.

When Apple adds new fancy graphics or better multitasking to your iPhone, your phone has to do more work. It's like asking a computer to do more tasks – your iPhone slows after iOS 17 update because it's got a lot to handle.

Moreover, it can be worse if you are using an older iPhone model. As iOS gets fancier, older iPhones might struggle to keep up. Apple tries to make the new iOS work on old phones, but sometimes, it's like fitting a big puzzle piece into a small space. This can make your phone feel sluggish.

Over time, your iPhone accumulates system cache, temporary files, and residual data from apps and processes. These files are designed to expedite specific operations, but they can become problematic if they become too fragmented.

Imagine your room getting messy over time. Your phone collects files and leftovers from apps, and this can make it slow. When you update, these files can make your phone confused and sluggish.

Now, let’s fix this issue.

Part 1: Immediate Steps to Improve iPhone Performance

If you've noticed that your iPhone running slow after update iOS 17, here's a quick method you can employ as your initial solution:

1) Force restart the iPhone to clear temporary glitches

If your iPhone's responsiveness has taken a hit, a quick force restart might do the trick.

  • For earlier iPhone models (iPhone 6/6S and below):

Press and hold the volume down button along with the power button until you see the Apple logo.

  • On the latest iPhone models:

Hold the volume down and power buttons at the same time until your iPhone restarts itself.

This action can clear out temporary glitches that might be affecting your phone's speed.

2) Close not responding apps

When iPhone becomes slow, you can forcefully close battery-draining apps like YouTube, Instagram or unresponsive apps before reopening them to reset my iPhone’s performance. This might be simple, but it works wonders.

For users with more recent models:

  • Step 1: Executing an upward swipe from the bottom of the display at the Home Screen.
  • Step 2: Pause briefly in the center of the screen during this motion.
  • Step 3: Swipe right or left to close the app.
  • Close data-hungry or unresponsive apps.

    If you're using an iPhone 8 or an earlier version, you can achieve this by double-clicking the Home button. It will show up a list of recently used apps.

    Next, navigate by swiping left or right to locate the specific app that requires closure. Once you've located the app, dismiss it by swiping upwards on its preview.

    Part 2: Manage iPhone Storage to Prevent iPhone Running Slow

    The next part that you can do to avoid frustrating iPhone running slow after update iOS 17 is managing storage space. Here is what you can do to manage your iPhone storage:

    1) Freeing up storage space on the iPhone

    When your iPhone's storage gets cluttered, it not only slows things down but also makes it hard to find what you need. Here's how to keep things tidy:

    Cleaning Up Unnecessary Files, Photos, and Videos:

  • Step 1: Start by going to your iPhone "Settings."
  • Step 2: Find "General" > “Storage."
  • Step 3: Look at the list of apps and how much space they use.
  • Step 4: Remove apps you don't really need by tapping on them and selecting "Delete App."
  • Manage iPhone storage.

    Don't forget to also regularly clean up your Camera Roll by deleting duplicates and old photos and videos.

    2) Using Cloud Storage to Offload Data:

    To improve your iPhone's performance and prevent such issues, you can use cloud storage like iCloud. Think of these as online storage spots. Your stuff is safely stored there, allowing you to remove things from your iPhone and create more room. Here's how:

  • Step 1: Open "Settings," then tap your name at the top and choose “iCloud.”
  • Step 2: Under Apps Using iCloud, manage which type of data you want to store in the cloud. Make sure their toggle is on.
  • Manage iCloud on iPhone.

    You can also get apps for other cloud services from the App Store. Use them to store files you want to keep but don't need on your device.

    Part 3: Check Background Apps and Processes

    Next, you can check and manage the background apps on your iPhone to optimize them. iPhones are equipped with various apps and processes that run in the background. While these background activities can enhance your user experience, they also consume battery life and system resources.

    Managing background app refresh settings and limiting app permissions can help optimize your device's performance. Now, I'll show you how to take control of these settings and ensure your device operates efficiently.

  • Step 1: Go to Settings > General
  • Step 2: Under the General settings, Select Background App Refresh and make sure it’s on.
  • Enable the Background App Refresh.

    Part 4: Reset iPhone Settings

    For this method, it’s only advisable if you have your data backed up on iCloud. It is because a factory reset could erase all data and settings on your iPhone. Then, it returns your iPhone to its original out-of-the-box state.

    If you want to proceed, here's how to perform a factory reset with data backup:

  • Step 1: Go to iPhone’s "Settings" > "General."
  • Step 2: Scroll until you locate "Transfer or Reset iPhone."
  • Step 3: Opt for "Reset all settings." If prompted, enter your device passcode and Apple ID password.
  • Step 4: Confirm your decision to erase the device.
  • Reset all settings on iPhone.

    After the reset, your iPhone will restart. Here, you’ll need to set up your device as if it were new. During the setup process, follow the steps to restore your data:

  • Step 1: Choose to restore from an iCloud backup.
  • Step 2: Sign in to your Apple ID account and select the appropriate backup to restore from.
  • And tada! Your iPhone restarts like new (on the inside). By performing a factory reset with a data backup, you can potentially resolve more complex issues that might be affecting your iPhone's performance.

    Part 5: Always Viable Solution-Use the Best iOS System Repair Software

    Besides seeking help from Apple Support, you have another option to consider when dealing with stubborn iPhone issues: repairing the iOS system itself.

    Sometimes, ongoing problems can stem from deeper software-related causes, making a system repair an effective approach. For this matter, I usually use Dr.Fone iOS System Repair tool as it offers a comprehensive solution to address various iOS-related issues.
