Your iPhone 12 has been working normally since you started using it, but then you begin to notice a significant dip in the device’s performance.

Perhaps a certain app of feature is taking longer than normal to open or the iPhone takes longer to implement the input commands you give it.

Lagging issues on iPhone 12 are often as a result of problems with the firmware.

Fortunately, they are relatively easy to resolve as the solutions in this article will demonstrate.

Let’s get started with the first thing you should do when faced with performance issues on your iPhone 12.

Clear Background Apps

The first thing to do when there is a significant drop in the iPhone 12’s performance is to close any apps that are running in the background.

Even if you are not using them, these apps still take up a considerable amount of your iPhone’s RMA and CPU.

Some apps will even crash if you leave them idle for too long, with the most common culprit being gaming apps.

Here’s how you can close any apps that may be running in the background:

  • Step 1: Swipe up from the bottom of the screen and pause at the middle. This will allow you to see all apps running in the background.
  • Step 2: Swipe up on each app preview to close it.

Delete Unused Apps

Your iPhone will lag if there are too many apps on it. This is because the more apps you have, the more strained your device’s resources will be.

You can start by checking the amount of storage space that your apps are taking up and then deciding which ones you can live without.

Here’s a step-by-step guide to do that:

  • Step 1: Open the Settings app.
  • Step 2: Go to General > iPhone Storage to see all the apps on your iPhone and the amount of storage space they are taking up.
  • Step 3: Tap on the app that you would like to delete to select it and in the next screen, tap “Delete App.”
  • Step 4: In the popup that appears, tap “Delete App” to complete the process.

Delete Unused Apps

You can also turn on “Offload Unused Apps” and iOS will automatically delete any of the unused apps on your device whenever you run low on storage.

Update the Apps on iPhone

Your device will also experience a lot of performance problems if the version of iOS running on the device is outdated.

The same is true of your apps: if they are not up to date, they will function at less-than-optimal levels, thereby affecting the overall function of the device.

Start by checking for an iOS update. To do that, go to Settings > General > Software Update and if an update is available, tap “Download and Install” to update the device.

Point updates are more useful at delivering bug fixes that can help in this case more than milestone upgrades. For example, you want iOS 15.2.1 rather than iOS 15 in this case.

In the same way, you also want to check for updates to the apps you are using. App developers will often update the apps to ensure they remain stable and are compatible with the latest version of iOS.

In fact, we recommend updating your apps soon after an iOS update, just to make sure that everything is working correctly.

You can update the apps in the App Store and you can also enable automatic app updates to ensure that your apps will remain updated.

Clean Up the Storage on iPhone

When there are a lot of old unused files and data on your device, you may experience a significant dip in the performance.

This is not uncommon since over time, you are likely to accumulate a lot of data and files on the device.

Remove these files from the device and you will see an improvement in the device’s performance.

But before you can do that, you will first of all need to check how much storage space you have on your device. Follow these steps to do that:

  • Step 1: Open Settings.
  • Step 2: Tap on the “General” option.
  • Step 3: Then select “Storage & iCloud Usage”.
  • Step 4: Tap “Manage Storage”.

Your iPhone will show you how much storage space you have left. If you find that you don’t have adequate storage space left, go back to “General” and tap “iPhone Storage” to see the types of data and apps that are taking up too much space.

You can then decide which files or apps you can delete to create more storage space.

Clear Browser History & Data on iPhone

If you are not comfortable deleting some of your apps or data, you can free up some memory on your device by clearing out the browser’s cookies and data.

For the Safari browser:

  • Step 1: Open the Settings app and tap “Safari.”
  • Step 2: Scroll down to tap on “Clear History and Data.”

Doing this will remove the browsing history, cookies and other data from Safari on all devices that share the same iCloud account. Tap “Clear History and Data” again to confirm.

For Google Chrome browser:

  • Step 1: Open the Google Chrome browser on your device and then tap on the three horizontal lines at the bottom to open the menu.
  • Step 2: Select Settings.
  • Step 3: Tap “Privacy” from the options and then select “Clear Browsing Data.”

You will the be able to select the type of data that you want to delete. If there is a very heavy lag on the device’s performance, you may want to delete everything.

Force Restart Your iPhone 12

While deleting some of the apps and data on your device can improve the performance, the iPhone will also greatly benefit from a force restart.

This is because a force restart will refresh the memory and reload all the features and services running on the device.

Force restarting your iPhone 12 is a simple process: just press and let go of the Volume Up button, do the same very quickly with the Volume Down button and then press and hold the Side button for about 12 seconds.

Let go of the Side button when the Apple Logo appears on the screen and wait for the device to complete the reboot procedures.

Reset All Settings on the iPhone

A force restart should be able to help, but if you notice that the device is still lagging, you may want to reset all settings on your iPhone.

This is an effective solution because it will reconfigure all the settings on your device, thereby removing any conflicting settings there may be.

Note that this solution will not affect any of the data on your device.

To do it, go to Settings > General > Reset > Reset All Settings.

When prompted, enter the device’s passcode and the tap “Reset All Settings” again to confirm that action.

The iPhone will reboot and you can then test if the device’s performance has improved.
