How to speed up iPhone: tips from software engineers

An iPhone is literally an iSelf. We use iPhones to connect, communicate, navigate and even pay for our purchases. So it is almost impossible to imagine that you would leave your house without your phone. When an iPhone is slow, it feels like your life is slowing down, too, because you can’t go about your day with the same efficiency and speed.

We asked the software engineers at Tech about the most common reasons for iPhone running slow and ways to fix this problem. And this is what we learned.

Why is iPhone running slow?

It’s not always easy to pinpoint why an iPhone starts acting slow. Even more, sometimes it is impossible, and you will have to use universal fixes such as restarting your device to get your phone back to its usual speed and performance. Still, there are a few things that directly affect the speed of the iPhone, and here they are:

  • Bad internet connection. How to fix:
    • Switch to a different network
    • disable vpn
    • Reset the network settings on your iPhone.
  • Junk files clogging up storage. How to fix:
    • Remove redundant data, including all duplicates and similar files
    • Scan your iPhone for bloatware and malware
    • Delete unused apps.
  • Outdated iOS or system software. How to fix:
    • Update your iOS
    • Get rid of beta versions of iOS.
  • Battery problems . How to fix:
    • Check the battery status and take your device to an Apple Authorized Service.
  • RAM overloaded . How to fix:
    • Quit or remove apps that are slowing down your device.
  • Too many apps use app extensions. How to fix:
    • Disable background app refresh.
  • Motion and brightness need to be adjusted. How to fix:
    • Reduce screen brightness and change motion settings.

Sounds like a serious troubleshooter! Don’t worry, we’ve provided step-by-step instructions on how to address each of these issues below. But first, let’s tackle the popular “Apple does it on purpose” myth.

Why do iPhones get slower over time?

Some people say that they notice their iPhone running slow and hot after new iPhone versions are released. The logical question remains: could Apple deliberately slow down older iPhones to boost sales of newer models? Sounds like a great conspiracy theory, but the answer is no, Apple doesn’t do that and it has been disproved through numerous studies.

However, Apple did acknowledge that an older iPhone might run slower if its battery is very depleted. The iPhone deliberate slowdown algorithm was developed to prevent the iPhone from randomly turning off. That is why one of the most useful recommendations is to always check the battery status when you notice that the iPhone is slowing down.

How to make your slow iPhone work faster

Unless your iPhone’s battery health has seriously deteriorated, you don’t have to rush to buy a new phone right away. Instead, try some working solutions recommended by our software engineers.

Repair your internet connection

Sometimes we falsely blame our iPhones for slowing down when, in fact, we are having internet problems. In fact, poor network connection in crowded spaces or sub-optimal router settings can cause slow feedback in the user interface, giving us the impression that our iPhone is acting slow.

Switch to a different network

The easiest way to check this is to switch to another network, if one is available to you. Did your connection improve? If so, now you know who the villain is.

You can also try force closing some apps that seem slow and see if the connection improves.

Disable vpn

serhii popov, a software engineer at Tecnologar, also recommends checking if you have any VPN services enabled. Some VPNs can block crucial domains used by system apps and services, leading to network issues.

For future use, get a VPN you can trust, like ClearVPN. Not only is it a reliable and secure service, but it also boasts a stellar user interface, with shortcuts that allow you to switch between different VPN tasks. Through Tech, you can try ClearVPN for free, both on iPhone and Mac.

Reset network settings

If network problems persist, the last thing you should try is to reset your network settings.

According to Vitalii Budnyking, Tech’s staff software engineer, resetting network settings has a major downside: You’ll need to re-enter your Wi-Fi password and set up the carrier’s network if it was done manually (which is rare in these days).

  1. Open Settings on your iPhone and go to General > Transfer or Reset iPhone
  2. Touch Reset
  3. Tap on Reset Network Settings and enter your iPhone passcode
  4. Touch Reset network settings to confirm the reset.

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

Clean up storage

If your iPhone is literally suffocating with barely any free storage space left, it may start to slow down. This is what you should do.

Remove redundant files

Files that you clearly don’t need on your device are duplicates. Gemini for iOS will scan your iPhone for duplicate files and the like, which you can then delete with one click.

If you want to move some of the files to another location instead of deleting them, there are other Tech helpers that will come in handy here: AnyTrans for iOS and Dropshare. The former is a content management app for Mac that you can use to move data from iPhone to Mac. And the latter is a simple tool to upload your files to the cloud, with 10GB of add-on storage for Tech users.

Scan your iPhone for bloatware and malware

Some of the apps on your iPhone, mostly the pre-installed ones, can run in the background for no reason, send spam notifications, or annoy you with ads and special offers. These applications are called bloatware. To fix slow iPhone performance, remove all apps that act as bloatware. If you have a secure malware scanner, we suggest that you also scan your iPhone for malicious files and programs because they consume a lot of performance as well.

Delete unused apps

Every app you don’t use sucks up the resources of your iPhone. Some might even run in the background, putting a lot of stress on the processor. Be sure to check your app’s toolkit regularly and uninstall any apps you don’t use. It’s easy to do if you use services like Tecnologar.

Technology is the ultimate app subscription for macOS and iOS, with over 240 apps that you can install and uninstall with a click. For example, if you need to solve a quick task (extract an image from a video or create a mind map), you can simply install a relevant app, complete your task, and uninstall it. No need to buy apps, your Tech Them monthly fee covers them all.

Search for updates

A quick answer to the question “why is my iPhone so slow?” it could be “because you need to run a software update.” In fact, new versions of iOS often fix performance bugs and make an iPhone run faster, so it makes sense to keep your iOS up to date.

Update iOS

  1. On your iPhone, open Settings
  2. Go to General and tap on Software Update
  3. If there are pending updates, touch Download and install.

Get rid of beta versions of iOS

“Betas are known to not be fully optimized (although all iOS betas worked pretty well last year). If this is your case, wait for the stable version or go back to the latest stable version of iOS,” recommends Tecnologar software engineer Serhii Popov.

Check battery status

As we mentioned earlier, iPhone running slow could be caused by deteriorating battery health. You can check how your battery is doing in Settings > Battery > Battery health. In case your battery is dead, Maksym Kotli, Software Engineer at Tech, recommends the following: “Have professionals replace it at an Apple Store/Apple Authorized Service Center because only licensed services have access to genuine parts. from Apple”.

Fix overloaded RAM issue

Although Apple limits RAM consumption per app, if you have too many resource-intensive apps running on your iPhone simultaneously, they can slow down your device. Tip from our software engineer, Serhii Popov: “If you work with apps like 3D editors, video editors, etc., try force closing them or even rebooting your device.”

Disable background app refresh

Maksym Kotliar, software engineer at Tecnologar, mentions another possible reason for the slow performance of the iPhone: “extensions can work in the background while an application is not running. For example, searching feeds or uploading content for notifications.” To fix this, you need to disable background app refresh:

  • go to settings
  • Scroll down and tap on the app name
  • Turn off background app refresh if it is enabled.

Change brightness and motion settings

Another method to fix slow iPhone could be to adjust the brightness and motion on your device. Even slightly reducing motion and brightness will result in energy savings, which could improve your iPhone’s performance. Here’s how to reduce shake on iPhone:

  1. Go to Settings > Accessibility
  2. press movement
  3. Turn on Reduce Motion.

Optionally, you can also adjust some other motion settings. For example, turning off autoplay message effects will save power.

And this is how you can reduce screen brightness to fix slow iPhone:

  1. Go to Settings > Display & brightness
  2. Use the slider to reduce the brightness
  3. Enable Night Shift to have your iPhone automatically lower the brightness in dark environments.

iPhone running slow is not a death sentence

Slow iPhone performance issues are common, and it doesn’t always mean you need to replace your device. Yes, in some cases slow iPhone indicates poor battery health which is the hardest thing to fix. However, most of the time, tweaking a few settings and getting rid of resource-intensive apps will do the magic and make your iPhone run faster.

So what is the last piece of advice? Invest in iPhone maintenance and get your apps from trusted sources like Tech. It’s secure, easy to use, and covers most of the apps you need on your Apple devices.
