Why Do Background Apps Slow Down Your Phone? Here’s How to Close Them the Right Way

If your smartphone feels slow, hangs often, or drains battery quickly—even when you’re not actively using it—background apps are usually the hidden reason. These apps keep running silently in the background, consuming system resources without you noticing.

Let’s understand why background apps slow down your phone and how to control them properly on Android and iPhone.


How background apps slow down your phone

  • RAM, leaving less memory for active apps

  • CPU power, making the phone lag or stutter

  • Internet data, as many apps keep syncing in the background

Apps that send frequent notifications, track location, or auto-sync data keep the processor busy. This directly affects speed, smoothness, and multitasking performance.


Battery and data drain issues

  • Drain battery faster by constantly waking the processor

  • Consume mobile data while syncing with servers

When battery levels drop, smartphones automatically reduce performance to save power, which makes the phone feel even slower.


How to close background apps properly on Android

Instead of force-closing apps repeatedly, follow these steps for better results:

  1. Go to Settings → Battery → Battery Usage

  2. Tap on apps consuming excessive battery

  3. Select Restrict background activity for non-essential apps

You can also:

  • Go to Settings → Apps → App name → Permissions

  • Turn off unnecessary Location, Background Data, and Notifications

This method is safer and more effective than using third-party cleaner apps, which often cause more harm than good.


How to control background apps on iPhone

Apple manages apps intelligently, but you can still optimize performance:

  1. Go to Settings → General → Background App Refresh

  2. Turn it off completely or allow only essential apps

Additionally:

  • Limit Location Access to “While Using the App”

  • Reduce unnecessary notification permissions

Avoid force-closing apps frequently on iPhones—iOS handles memory management automatically.
