Why is iPhone running slow?

It is not easy to accurately determine the reason why iPhones run slowly. What's more, sometimes it's impossible to determine the cause at all, and you may need to use a universal repair method, such as resetting the device, to get your phone back to normal running speed and performance. Still, there are some factors that directly affect the speed of the iPhone, and they are:

• Poor network connection. Solution:

• Switch to a different network

• Disable VPN

• Reset iPhone's network settings.

• Junk files take up storage space. Solution:

• Delete redundant data, including all duplicate and similar files

• Scan the bloatware and malware on iPhone

• Delete unused applications.

• iOS or system software is outdated. Solution:

• Update your iOS

• Uninstall iOS beta.

• Battery issues. Solution:

• Check the battery health and send the device to an Apple-authorized service center.

• RAM overload. Solution:

• Close or delete applications that cause the device to slow down.

• Too many applications use application extensions. Solution:

• Turn off background application refresh.

• Movement and brightness need to be adjusted. Solution:

• Reduce screen brightness and change motion settings.

Sounds like some rigorous troubleshooting is needed! Don't worry, I'll provide step-by-step instructions below to guide you on how to deal with each issue. But first, let's address the popular rumor that "Apple does it on purpose".

Why does the iPhone slow down over time?

Some say they noticed their iPhones running slowly and hot after the new iPhone was released. This creates a logical question - has Apple deliberately slowed down the speed of older iPhones to promote sales of new phones? This sounds like a great conspiracy theory, but the answer is no, Apple did not do it, and this statement has been refuted by countless studies.

However, Apple does admit that if the battery of older iPhones is severely worn, its performance may slow down. The algorithm that deliberately slows down iPhones is to prevent such iPhones from being shut down randomly. That's why one of the most effective tips when you notice your iPhone is slowing down is to always check your battery health.

How to improve the running speed of slow iPhones

Unless your iPhone battery health worsens seriously, you don’t have to buy a new phone right away. Instead, try some effective solutions recommended by Setapp's software engineers.

Repair your network connection

Sometimes, when we actually have network problems, we mistakenly blame the phone itself for slow running of the iPhone. In fact, poor network connections can lead to slow UI feedback in crowded space or in poor router configuration, which can make us feel like the iPhone is running slowly.

Switch to a different network

The easiest way to verify this is to switch to another network (if available). Has your connection improved? If so, you know who the culprit is.

You can also try forcefully closing some apps that seem to cause iPhone stutter to see if it can improve connections.

Disable VPN

Setapp's software engineer Serhii Popov also recommends checking if you have enabled any VPN services. Some VPNs may block critical domains used by applications and system services, causing network problems.

For later use, choose a trusted VPN, such as ClearVPN. Not only is it a reputable and secure service, it also has a great UI and comes with shortcuts that allow you to switch between different VPN tasks. With Setapp, you can try ClearVPN for free on iPhone and Mac.

Reset network settings

If the network problem persists, the last thing to try is resetting the network settings.

According to Vitalii Budnyk, a senior software engineer at Setapp, there is a major drawback to resetting a network setup: you need to re-enter your Wi-Fi password, and if you manually configure the carrier network (which is rare now), you need to reconfigure it.

1. Open Settings on your iPhone and go to General > Transfer or Reset iPhone.
2. Click "Reset".
3. Click “Reset Network Settings” and enter your iPhone password.
4. Click "Reset Network Settings" to confirm the reset.

This is how to speed up your iPhone if you have network problems.

Clean up storage space

If your iPhone "suffocates" with little left over storage, it may start to slow down. Here are the things you should do.

Delete redundant files

Duplicate files are files you obviously don't need to save on your device. CleanMy® Phone will scan duplicate files and similar photos and videos on your iPhone, and you can delete them with one click.

Having said that, I know not everyone likes to clean up their phones carefully. Many of my friends just upload their files to an external hard drive or to the cloud. If you also prefer to store files in the cloud and use multiple cloud services, Dropshare may be the perfect app for you. It allows you to connect all your cloud accounts in one interface, allowing you to upload files directly without any hassle.

Scan the bloatware and malware on iPhone

Some apps on your iPhone (mostly pre-installed apps) may run in the background for no reason, send spam notifications, or bother you with ads and special offers. Such applications are called bloat software. To solve the problem of slow iPhone performance, remove all applications that act as bloat software. If you have a secure malware scanner, I suggest you also scan malicious files and programs on your iPhone, as they are also huge performance consumers.

Delete unused applications

Every app you don't use will consume your iPhone resources. Some applications may even run in the background, putting huge pressure on the processor. Make sure to check your application kit regularly and uninstall unused applications. This is easy to do if you use services like Setapp.

Setapp is the ultimate app subscription service for macOS and iOS, with over 250 apps that you can install and uninstall in one click. For example, if you need to complete a quick task—extract images from videos or create mind maps—you can just install relevant applications and uninstall them after completing the task. No need to purchase an app, your monthly Setapp fee covers all apps.

Check for updates

A quick answer to answer "Why is my iPhone so slow?" could be "because you need to run software updates". In fact, new iOS versions usually fix performance bugs and make iPhone run faster, so it makes sense to keep iOS updated.

Update iOS

1. On your iPhone, open Settings.
2. Go to General and click Software Update.
3. If there are any pending updates, click "Download and Install".

Uninstall iOS beta

Serhii Popov, software engineer at Setapp, suggests: "Beta versions are well known to be not fully optimized (although all iOS betas last year ran quite well). If this is your case, either wait for the stable version to be released or roll back to the latest stable version of iOS."

Check the battery health status

As I mentioned earlier, the slow iPhone run may be due to worsening battery health. You can check the battery's condition in Settings > Battery > Battery Health. If your battery is out of power, Setapp software engineer Maksym Kotliar advises: “Let the professionals in the Apple Store/Apple Authorized Service Center replace the battery, because only authorized services can get genuine Apple parts.”

If you are thinking, "This fix is ​​too expensive and may not work", don't rush to draw conclusions. After receiving this suggestion, I browsed several posts on Reddit and many users confirmed that their five or six-year-old phones have improved a lot after replacing the battery. So if the other methods in this list don't work for you, it's worth considering this option.

Fix RAM overload problem

Although Apple limits RAM consumption per app, they may slow down the device if you run too many resource-intensive apps on your iPhone at the same time. Tip from our software engineer Serhii Popov: "If you use applications like 3D editors, video editors, etc., try forcefully shutting them down or even restarting the device."

My experience usually, unless your phone starts to stutter, consumes too fast or even has a black screen, you won't realize that your phone is using too much memory. That's why I'm paying special attention to monitoring my iPhone's performance. I installed Usage and added its parts to my screen so I could always keep up with the key information about my iPhone.

Disable background application refresh

Setapp's software engineer Maksym Kotliar mentioned another reason that could cause slow iPhone performance: "Extensions can run in the background when the app is not running. For example, get feeds or load notification content." To fix this, you need to disable background application refresh:

1. Go to Settings > Applications.
2. Click on the application name.
3. If Backend Application Refresh is enabled, turn it off.

Change brightness and motion settings

Another way to fix slow iPhones might be to adjust brightness and motion on the device. Even a little bit of lowering your movement and brightness can save energy, which may improve your iPhone's performance. Here’s how to reduce exercise on your iPhone:

1. Go to Settings > Accessibility.
2. Click "Action".
3. Turn on "Reduce Action".

Alternatively, you can adjust some other sports settings. For example, turning off the autoplay of message effects will save you some energy.

Here is how to reduce screen brightness to fix slow iPhones:

1. Go to Settings > Display & Brightness.
2. Use the scroll bar to reduce brightness.
3. Enable Night Mode so your iPhone automatically reduces brightness in a dim environment.

iPhones are not the end of the world

The problem of slow iPhone performance is common, and this doesn't always mean you need to replace the device. Yes, in some cases, the slow iPhone runs indicating poor battery health, which is the hardest problem to fix. But, most of the time, tweaking some settings and getting rid of resource-intensive applications can do a magical role to make your iPhone run faster.

So what is the final suggestion? Invest in iPhone maintenance and get your app from trusted sources like Setapp. It's secure, user-friendly, and covers most of the apps you need on your Apple device.

Setapp won't ask you to buy apps because you already have all the apps (including future updates) and just subscribe. Install and uninstall easily so your iPhone won't be too cluttered.
