If your iPhone feels slow, does not have as much space as it used to, or just doesn’t work like it should, this tip is a simple way to get more performance out of your device. Even the mightiest of iPhones slow down over time, and much of the time, it’s hard to fault age or hardware failure. In many cases, there are some apps to blame for that sluggish performance on your device. Some of those apps are memory hogs that, in a short period, drain smartphone batteries and run background processes that slow the thing down.

In this article, we’ll cover the 10 apps that could be slowing down your iPhone a lot. Even more crucial: We’ll offer you tips on how to fix whatever’s ailing it without giving up access to the features you’ve come to rely on.

Why Your iPhone Feels Slower Over Time.

Apple builds its iPhones to provide a seamless user experience, but there are occasional hiccups in the operation of the device. Old hardware, outdated iOS versions, cluttered storage, and — most importantly- bad apps that are taxing your system can all be responsible for dragging the device down. The main suspects are apps that continuously refresh in the background, take up a lot of RAM, or crush your processor.

The issue is more than just an annoyance. A sluggish iPhone can make your phone a lot less effective — and even shorten your battery’s life. The good news is, once we know who the bad actors are, we can make our phone faster and more responsive.

Facebook: The Data Hog in Disguise.

Facebook is one of the downloaded and used apps in the world, and as you can see, one of the biggest slowdown triggers on the iPhone. It’s bitched out with tons of background processes — auto-refreshing feeds, syncing contacts, constant notifications. All of this sucks up your CPU and memory, even when you are not actively using it.

You may want to try the mobile browser version or disable background app refresh to mitigate its effect. If that isn’t of much assistance, deleting and then reinstalling the app will generally pare down that cached data, refreshing the app’s performance in the process.

Snapchat: Fun, Filters, and Frustration.

Snapchat has plenty of lighthearted filters and on-the-fly sharing tools, but it is a system resource hog. The app often runs in the background, accessing your camera, location, and microphone, and storing temporary data that can accumulate quickly.

This continual pull on your phone’s resources can cause it to overheat and lag. Frequently clearing the app cache or turning off features, such as location tracking, can help offload your iPhone’s burden.

Instagram: Pretty Pictures, Heavy Processes.

Sure, Instagram is innocuous enough, but it’s an essential resource hog. From the loading of high-res media to the background updates to the autoplay videos, the app takes a decent bite of your RAM and CPU power.

If you want to minimize its drag on your system’s performance, disable video autoplay and restrict background activity from within your iPhone’s settings. And periodically clearing the app’s cache may also help notice the difference.

TikTok: Endless Entertainment, Endless Load.

There is a reason TikTok is so addictive —its algorithm is browsing in the background, serving up content according to how you are using the app. But feeding these kinds of real-time results also costs us storage, memory, and mobile data.

If you leave this app open or use it for a long time, it is one of the major culprits of performance slowdown. You can put in screen time limits or access the browser version if you feel the app is making your phone very slow.

YouTube: The Streaming Giant That Eats Up Resources

From binge-watching shows to streaming the soundtrack to your run, YouTube puts a serious drain on your iPhone’s processor and battery. It also keeps loading content while you’re not watching anything, especially if you’re using YouTube Premium with background play.

To prevent data from getting bogged down, lower the video resolution when streaming, turn off autoplay, or delete an app’s watch history and cache. If that doesn’t help, then try unloading the app and then reinstalling it.

Google Maps: Navigation with a Side of Lag.

Navigation is essential, but Google Maps can otherwise slow your iPhone to a crawl. It does all these while it is utilizing GPS all the time and even storing those maps and syncing updated information simultaneously.

If you’re not using it, be sure you shut it down properly and limit location access to “While Using the App.” You can also access to download offline maps, which takes less memory while navigating.

Safari: The Browser You Never Thought Would Lag.

Safari is Apple’s in-house browser, but this doesn’t exempt it from performance issues. If you have dozens of tabs open, enable cookies, or fail to clear your history and website data, you may find Safari slowing down your entire iPhone experience.

To quickly spiff up your storage, visit Settings > Safari > Clear History and Website Data. And, yes, think about employing content blockers, which can cut down the number of scripts and ads a site loads.

Spotify: Music to Your Ears, Not to Your iPhone.

Spotify can be surprisingly resource-intensive, particularly if you’re downloading audio for offline listening or are trying to stream music at high quality. It stays running in the background as well to sync playlists and monitor usage.

You can minimize its impact by lowering download quality, turning off autoplay, and keeping it from refreshing in the background. Uninstalling and reinstalling the app now and then is another way to help clear bloated data.

Zoom: Video Calls That Freeze More Than Conversations.

Zoom is essential for remote work and meetings, but it’s one of the biggest iPhone resource hogs you can install. Live video, screen sharing, and running in the background all chew up RAM and CPU resources.

To enhance performance, close all other applications before running Zoom and disable HD video settings when you don’t need them. Do not use the background up feature if you are not using it.

Chrome: Google’s Speedy Browser That Slows iPhones.

There are a lot of people who like Chrome better than Safari, and for them, you’ll want to recommend it, especially since it doesn’t have the Notes feature that Safari does. Chrome is also more of a memory and battery eater because it duplicates several services that are built into Safari, including bookmarks and syncing.

To minimize its drag on your system, close down all your tabs, turn off any superfluous extensions, and periodically clear your browser data. If you don’t use it, Safari is a speedier alternative.

How to Identify and Manage Resource-Hungry Apps.

iOS has tools to help figure out what’s slowing your device down. And you can visit Settings > Battery to see which apps are using the most energy, or Settings > General > iPhone Storage to see which apps take up the most space. These statistics often correlate with performance problems.

When you’ve fingered the culprit, you have several courses of action:

• Turn off background app refresh
• Offload the app and reinstall
• Ask the apps to use less of your data (and access your location, camera, and microphone, for instance).
• Use browser alternatives
• Set screen time limits

Taming these settings may not mean deleting the apps entirely, but when you use them with more purpose, there’s a world of difference.

When It’s More Than Just Apps.

Occasionally, your iPhone’s issues are more serious than apps. If the software is corrupted, infected with malware, or suffers physical damage, it will most likely end up in slow performance, loss of data, or system crash. If closing and managing apps doesn’t work, consult a professional for diagnostics or repairs.

When your iPhone becomes sluggish or even completely unresponsive, get professional help, like iPhone Repair services in Weston, FL, to restore its performance without the risk of data loss. And when it comes to times when important files are deleted as a result of troubleshooting, you can also make use of iPhone Data Recovery Services, which is dedicated to restoring photos, messages, contacts, and app data safely.

Conclusion

Your iPhone is probably one of the smartest things you own, but even smart things get bogged down with the wrong kind of sometimes-useful apps. Once you know the worst offenders and adapt smarter usage habits, you can increase your iPhone’s life, save on battery, and enjoy a smoother experience.
