How To Fix It If Apple iPhone 13 Keeps Lagging (iOS 15)

The Apple iPhone 13 is one of the fastest, most responsive smartphones today. But even if that’s the case, there will always come a time when its performance starts to deteriorate and it’s not because it’s defective but due to some apps and services that may have accumulated a lot of data already.

For instance, if you already have a lot of background apps that are use the RAM and CPU of your iPhone, you can expect that it will start to lag or become sluggish at some point. Some of them might even be rogue apps that cause more issues and affect other services.

Lagging and freezing are among the most common performance issues you may encounter after a few months of use. But the good thing is you can fix them easily with very little effort.

Troubleshooting iPhone 13 That Keeps Lagging

Another possibility as to why your device lags is when the iPhone storage is running low. Sometimes, lags and freezes occur shortly after trying to update a new iOS version and failed.

When such a problem occurs, it’s because the iOS update has already been downloaded on your device but your iPhone failed to install it. As a result, the update took up a huge chunk in your storage and that can potentially cause various issues.

It is also possible that you already have a lot of out-dated apps. As one of the many iPhone users that encountered this problem, try troubleshooting your device and see if you can make it work smoothly again.

Don’t worry, the steps are easy and safe to do. With that said, here are the effective solutions to this problem:

First solution: Close background apps

Before anything else, what you have to do is close the running apps suspended in the background as they often use up a lot of RAM and CPU that cause lagging and freezing.

It’s the easiest and safest procedure you can do in fixing this problem.

Here’s how it’s done on your iPhone 13:

Step 1: Swipe up from the bottom of the screen to view the app previews.
Step 2: Now swipe up on each app preview to close them one after another.

When all apps running in the background are closed, try to see if the problem still persists. If it does, then move on to the next solution.

Second solution: Do the Forced Restart on your iPhone

After closing the apps and the iPhone touchscreen lagging problem persists, your next option is to force restart your device.

It is a simulated battery removal that refreshes your phone’s memory and reloads all apps and services. If the lags and freezes are due to a minor firmware issue, then this should be enough to make your iPhone 13 run smoothly again.

Here’s how it’s done:

Step 1: Quickly press and release the Volume Up button.
Step 2: Press and quickly release the Volume Down button.
Step 3: Immediately after releasing the Volume Down button, press and hold the Power button for 8 seconds.

Your iPhone will shut down and power back up.

Step 4: When the Apple logo appears, release the Power key and allow the device to continue the boot process.

Once your iPhone has finished rebooting, try to see if the lags are gone.

Third solution: Do the Settings reset on your iPhone

After closing all apps and doing the forced restart and your iPhone is still lagging, what you need to do next is to reset all settings. It is not a full system reset but it’s often enough to fix performance issues like this.

The good thing about it is that none of your files will be deleted, so you don’t need to create a backup of your important staff. Here’s how it’s done on your iPhone 13:

Step 1: Launch the Settings app.
Step 2: Tap General.
Step 3: Scroll down and tap Transfer or Reset iPhone.
Step 4: Tap Reset at the bottom of the screen to reveal all the options.
Step 5: Tap the Reset All Settings option and enter your security lock if prompted.
Step 6: Tap Reset All Settings at the bottom of the screen, and then confirm it by tapping the same option.

Your iPhone will reboot when all settings are reset but don’t worry, you don’t have to set up your device again. But once it’s ready, try to see if your device is still lagging or if the problem is already fixed.

Fourth solution: Factory reset your iPhone

Most of the time, performance-related problems can get fixed by the first three solutions, especially if the issue is with your iPhone’s operating system. However, if your device continues to lag even after doing them, then it’s time to bring it back to factory settings.

Bear in mind that all your personal files and settings will be deleted when you reset your iPhone. Therefore, you need to create a backup of the things you don’t want to lose before doing the master reset.

Once you’re ready, follow these steps to reset your device:

Step 1: Return to the Home screen and tap Settings.

Step 2: Tap General.

Step 3: Scroll down and tap Transfer or Reset iPhone.

Step 4: Tap the Erase All Content and Settings option at the bottom of the screen.

Read the information on the screen as it’s important because it tells you which ones will be deleted. You can use the information to backup your data.

Step 5: Tap Continue and then enter your security code if prompted.

You will then be prompted to turn off the Activation Lock by entering your Apple ID password.

Step 6: Enter your Apple ID password and tap Turn Off at the top-right corner of the screen.

Now follow a few on-screen instructions to proceed with the Factory Reset.

Once the reset is complete, set up your iPhone 13 until it becomes ready and then try to see if the lagging and freezing issues still occur. If they do, then move on to the next solution.

Fifth solution: Restore iPhone via DFU Mode

Before you actually go to the Apple Store and have the tech check the device for you, it’s better that you try doing the Recovery mode restore. It’s almost the same as the factory reset only that this time, a new operating system or iOS version will be installed if available.

What you need to accomplish this is Windows or Mac computer and the original lightning cable. The Apple Support tech will do this procedure at the Genius Bar that’s why we always suggest you try it before having a professional check your iPhone.

We hope that this troubleshooting guide can help you fix your iPhone 13 that keeps lagging.
