Yes constantly close apps on your iPhone while trying to speed things up or save battery life, you are doing the opposite and making your iPhone perform worse. This is why.
iPhone manages system resources automatically
Many people may be familiar with how applications run on a Mac or Windows PC. On those platforms, if an application is running in the background, it may still be consuming CPU cycles or taking up RAM. Conventional wisdom says that closing those programs will make your PC or Mac run better.
On an iPhone, things work differently: when give up an application, the application enters a suspended status and iOS automatically frees the CPU and RAM cycles that were dedicated to running the application. The iPhone’s automatic resource management is so good that you never have to worry about an app paused in the background slowing down the app you’re using in the foreground.
Officially, Apple says “You should close an application only if it is not responding.”
Relaunching apps hurts performance and battery
In fact, when you force close an app on your iPhone, it will not only slow down the app experience, but which will also consume more battery . This is because once an application is completely closed, it is necessary to restart and reload all its resources the next time you open the application. That requires additional power from the CPU, which drains the battery faster. Relaunching a completely closed app is also slower than quickly switching to a suspended app.
So instead of increasing performance and saving battery, closing apps on iPhone regularly will do the exact opposite.
There is an exception, however. Sometimes a background application can search for new information. If that app is programmed incorrectly, it could consume more battery than usual. If an app is abusing your resources in the background, you may see evidence of it in the “Battery” section from the Settings app. In that case, don’t force quit. Instead, you can disable application update in background in Settings.
Sometimes you still need to close apps
Despite everything we’ve just written, there are still some legitimate reasons why you may need to force close an iPhone app . If an app stops responding or isn’t working properly, it’s a good idea to open the app launcher and close the app completely. To do this, you will need to perform a different action depending on the type of iPhone you have:
- On iPhone X or later: Swipe up from the bottom of the screen to the center of the screen, and then lift your finger.
- On iPhones with home buttons: press the home button located below the screen twice.
When App Switcher opens, you will see thumbnails of apps that are suspended in the background. To force close an app, swipe its thumbnail up, off the screen.
When the application disappears, the application has been completely closed. The next time you touch its icon, it will reboot.
Although Apple allows you to force close apps in this way, doing so should be very rare. iOS handles multitasking in an elegant and efficient way. Good luck!
