iPhone Lagging? 11 Fixes to Make It Smooth Again! [Video Guide included]

Jun 20, 2024 • Filed to: Data Wipe Solutions • Proven solutions

The iPhone is indeed a robust device compared to the average smartphone in the market. It is designed to last, and that is why iPhones tend to have a high resale value. However, it is not devoid of issues like iPhone 14 lagging or iPhone 7 lagging.

Well, iPhone lagging is undoubtedly annoying. It forces you to wait to execute certain tasks, a wait that wasn’t there before. In some cases, it takes too long to start up, and the screen even freezes during startup, which can be worrying.

Usually, lagging is a result of how we use our iPhones and what we use them for. For instance, the installation of too many applications can clog your memory and overpower your CPU speed. As a result, your iPhone 14 pro starts lagging and freezing altogether.

Also, back in the year 2017-2018, iPhone users began complaining about their phones suddenly behaving sluggishly after the iOS update. Apple came out explaining that an update they released slowed down the iPhones. Therefore, the sluggishness of your iPhone doesn’t leave you entirely to blame.

Such updates are for newer devices with faster CPUs, better memory (RAM), and fresh batteries.

So, this article is going to shade more light on why is my iPhone lagging or its apps, e.g., Snapchat lagging, and the possible solutions;

Part 1: When the iPhone becomes lagging

Some of the situations when your iPhone is lagging include moments when typing. It is a common problem with iPhone 14 users where it might not only be unresponsive but also predictions stop showing or get hidden.

It is consistent with the iPhone lagging after iOS 16 update. Updates always carry either new features or bug fixes. Either way, an update always brings in new software components. These can be having bugs/errors that can, as a result, cause your iPhone to malfunction in various ways.

Such malfunctions are usually also noticeable with third-party applications like WhatsApp and Snapchat. As they operate on your iPhone’s OS, an update can cause them to crash. At this point, the iPhone or iPad lags when starting the app, and in some cases, the app randomly closes.

Furthermore, a low battery charge can also cause your iPhone to lag. It happens because there is not enough power to support its operations.

However, there are solutions you can implement on your iPhone to stop the lag. Below are some of those solutions.

Part 2: 11 solutions to fix the iPhone lagging

Solutions to iPhone lagging include;

2.1 Clear system junk data in your iPhone

Daily system operations lead to the creation of junk files. These include code used to facilitate updates or in the installation of an app, image thumbnails for images that have already been deleted, amongst other content. As a result, the accumulation of junk files ultimately causes your iPhone to lag since there is no ‘breathing space’ for your iOS.

Therefore, you’ll have to wipe out these junk files, and one efficient way to do so is by using the Dr.Fone - Data Eraser tool. Why is it termed as efficient?

2.8 Turn off the auto-update feature

Apps often come with updates that include new features or improvements. These updates can take up additional storage space on your device.

Step 2: Select ‘Background App Refresh.’

Step 3: On the next window, tap 'Background App Refresh' to turn it off.

Step 1: Go to Settings and then General.

Step 2: Here, scroll down to find the ‘Reset’ option (or 'Transfer or Reset iPhone' > 'Reset').

While there are ways to boost your iPhone’s functionality, it is still essential to make sure that it doesn't get weighed down. Hence, when it comes to performing updates, you can try deferring them until you find a fix for whatever underlying issue.

Therefore, monitoring the number of apps we use at any given time goes a long way in keeping your iPhone snappy and efficient. Frequent closing of apps keeps your iPhone from lagging.

However, in extreme cases where your iPhone becomes unresponsive and shuts down from time to time, use the Dr.Fone - Data Eraser (iOS) toolkit for a factory reset.
