Closing apps on your iPhone might seem straightforward, but there's more to it than simply swiping them away. Understanding how to manage your open apps effectively impacts battery life, performance, and overall user experience. This guide will cover various methods and clarify some common misconceptions.
What Happens When You "Close" an App?
Before diving into the methods, let's address a crucial point: Swiping up on an app in the App Switcher doesn't truly "close" it in the same way you might close a program on a computer. Instead, it suspends the app. This means the app is paused, preserving its state (where you left off), but it's not actively using resources like CPU and RAM. The iPhone's operating system, iOS, intelligently manages background processes to conserve resources and optimize performance. Forcing the app to quit completely is generally unnecessary and could negatively impact its functionality.
How to Use the App Switcher: The Primary Method
The App Switcher is the most common way to manage open apps and, while it doesn't fully close them, it suspends them. Here's how to use it:
-
Swipe up from the bottom of the screen and pause slightly in the middle. This will bring up the App Switcher, displaying thumbnails of your recently used apps.
-
Swipe up on an app's preview to close it. This suspends the app, releasing its resources.
-
To close all open apps, swipe up on each app preview individually. There's no "close all" button.
Do I Really Need to Close Apps on My iPhone?
Usually, no. iOS manages background processes efficiently. Constantly closing apps won't significantly improve battery life or performance and can even be counterproductive. In fact, repeatedly closing apps can increase battery drain as the apps have to reload and restart each time you open them.
How to Force Quit an App (Only When Necessary)
There are times when an app might freeze or behave unexpectedly. In these cases, forcing the app to quit is necessary. This is different from simply suspending it.
-
Open the Settings app.
-
Tap on "General".
-
Tap on "iPhone Storage". (On older iOS versions, it might be under "Storage & iCloud Usage" then "Manage Storage")
-
Find the misbehaving app in the list.
-
Tap on the app to see its details.
-
Tap "Delete App".
-
Reinstall the app from the App Store. This forces a complete restart, effectively removing any problematic processes.
Why is My iPhone Slow? Is It Because of Open Apps?
Slow performance is rarely caused by too many open apps. More likely culprits include:
- Outdated iOS: Update your iPhone's software to the latest version.
- Storage Space Issues: A full or nearly full storage can significantly slow down your phone. Delete unused apps, photos, or videos.
- Resource-Intensive Apps: Some apps, especially games or editing software, consume more resources.
- Hardware Limitations: Older iPhones might naturally become slower over time.
Will Closing Apps Improve Battery Life?
Closing apps won't dramatically improve your battery life. iOS manages background processes effectively. Poor battery life is usually attributable to factors like screen brightness, location services, and background app activity (as mentioned before), and an older battery.
What Happens to My Progress in an App When I Close It?
Most apps save your progress automatically. When you reopen the app, you'll usually resume where you left off. However, some apps may require a manual save function.
This comprehensive guide should provide a clear understanding of how to manage your open apps on your iPhone, emphasizing the importance of efficient iOS resource management. Remember, letting iOS handle background processes is usually the most efficient approach for optimal performance and battery life.
