April 07, 2021Ashley Mae

Lagging or freezing is one of the common problems for mobile phones, and iPhone is no exception.

An old iPhone may be slow or lagging, however, why is a relatively new iPhone 12 lagging ?

That’s what we shall uncover.

In what follows, you will be aware of why your iPhone is lagging and how to speed up it in 5 solutions.

This post applies to all iPhone models like iPhone 12, 11, XS, XR, X, and so on.

iPhone Lagging

Part 1. Why Is My iPhone Lagging?

1. There are a variety of reasons why your iPhone might have slowed down. Here, let’s summarize as follows:

App activities run in the background

Even if you do not see an app running in your eyes, still some apps run in the background. For example, some apps may collect and send your personal information to their server. Those background activities may make your iPhone lagging to respond.

2. iPhone storage is almost full

if you have a large number of photos, videos, and other media files that store your iPhone storage, your device will be slower.

3. An old iOS version

Apple always updates its iOS version to optimize user’s experience, including speed-up. Moreover, the latest iOS update can fix some bugs that you may be experiencing on an older version. As a result, if your iPhone is running in an older iOS version like iOS 13, 12, 11, 10, and before, it may be experiencing a lagging state.

4. Internet connection is slow

Sometimes, you may find it is freezing when you try to install an application or play an online game. One of the most ignorant reasons is the Internet connection. A reliable Internet connection can guarantee a fast operation and vice versa.

5. An iOS update

Sometimes, an iOS update can bring you new features and bug fixes. Meanwhile, an iOS update may cause some problems the Apple developer team cannot find or solve that they could earlier. That’s why your iPhone is lagging after an iOS update.

6. Other reasons

Still, there are some other reasons for iPhone lagging, like iPhone overheating, iPhone damage, and more. Even Apple really does slow down older iPhones to better manage the battery.

If you have come across other reasons that cause your iPhone lagging, just leave your comments below.

After getting to know the reasons why iPhone is lagging, we can act appropriately to the situation truly in the next part.

Restart and Force Restart iPhone

Restarting a device works anytime.

To fix a freezing iPhone, the first method you should try is to restart your iPhone.

Let’s take iPhone 12, 11, or X as an example:

1. Press and hold either the Volume Down or Volume Up button and the Side button until the power off slider appears.

2. Drag the slider, and wait seconds and your iPhone will power off.

3. After a while, press and hold the Side button until you see the Apple logo.

Then your iPhone will restart.

There’s only one caveat: If your iPhone is lagging due to an iPhone overheat or coldness, you should wait for a long time until your iPhone temperature is normal, and then restart your iPhone.

However, if restart does not work to fix iPhone lagging, you can perform a force restart. A force restart will not erase any content but fix some common issues, like frozen iPhone, iPhone not turning off, etc. Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Then press and hold the Side button until you see the Apple logo.
