Does Turning Off Apps Running In The Background Save Battery

In an era where smartphones are essential for communication, productivity, and entertainment, battery life remains a top concern. One common piece of advice repeated across forums, tech blogs, and casual conversations is: “Close your background apps to save battery.” But does this actually work? Or is it a myth perpetuated by outdated habits? The answer isn’t as straightforward as a simple yes or no. It depends on how modern operating systems manage resources, what kind of apps you’re using, and how you interact with your device. Let’s break down the reality behind background apps and their impact on battery performance.

How Background Apps Actually Work

Modern mobile operating systems—iOS and Android—are designed with sophisticated memory and power management systems. When you switch away from an app, it doesn’t continue running full operations in the background. Instead, it enters a suspended or dormant state. In this state, the app uses minimal CPU and no network activity unless explicitly permitted for specific functions like music playback, location tracking, or push notifications.

On iOS, Apple refers to this as “app suspension.” Once an app is in the background, it’s frozen in memory. It consumes RAM but not significant processing power or energy. The system prioritizes keeping these suspended apps in memory because relaunching them from scratch takes more energy than resuming from a suspended state.

Android handles background processes differently depending on the version and manufacturer optimizations. While Android allows more flexibility for background services (especially for apps with permissions), recent versions have introduced aggressive battery-saving features like Doze mode and App Standby. These features limit background activity when the phone is idle, reducing unnecessary battery drain.

“Closing apps manually can sometimes do more harm than good. The system is optimized to manage memory efficiently, and restarting apps uses more power than leaving them suspended.” — Dr. Lin Xiao, Mobile Systems Researcher at MIT

The Myth of Manual App Closing

Many users believe that swiping away apps from the recent apps list stops them from consuming battery. However, this action rarely leads to meaningful battery savings. In fact, it can increase battery usage over time. Here’s why:

• Relaunch Overhead: When you force-close an app, the next time you open it, the system must reload it from storage, initialize its components, and reconnect to servers. This process uses more CPU and battery than simply resuming a suspended app.
• No Real-Time Drain: A suspended app isn’t actively using the processor or network. It’s like pausing a movie—you’re not watching it, but it’s ready to resume instantly.
• System Optimization: Both iOS and Android are built to automatically terminate apps when memory is needed. You don’t need to intervene manually.

For example, if you close your email app and reopen it later, it may take several seconds to load messages, sync folders, and refresh notifications—all tasks that consume additional power compared to a quick resume from suspension.

Tip: Avoid constantly swiping away background apps. Let the operating system manage them—it’s designed to do so efficiently.

When Background Apps *Do* Drain Battery

While most background apps are harmless, certain types of apps and behaviors can significantly impact battery life. The real culprits aren’t apps merely sitting in the background—they’re apps actively performing tasks without your knowledge.

These include:

• Location Services: Apps like fitness trackers, ride-sharing services, or weather apps that continuously access GPS can drain battery quickly, even when minimized.
• Background Refresh: On iOS, Background App Refresh allows apps to fetch new data periodically. If enabled for multiple apps, this can lead to frequent wake-ups and increased power use.
• Push Notifications: While individual notifications are low-power, apps that send constant alerts (e.g., social media, news) keep the radio active and screen lighting up.
• Auto-Sync Features: Email, cloud storage, and messaging apps that sync frequently in the background contribute to battery drain over time.
• Poorly Optimized Apps: Some third-party apps are not well-coded and may fail to enter a proper suspended state, continuing to run background threads unnecessarily.

Real-World Example: The Social Media Trap

Consider a user who keeps Instagram, TikTok, Twitter, and Facebook open in the background. They notice their phone battery drops from 70% to 40% in two hours while they’re reading a book—without touching their phone. Upon checking battery usage in settings, they find TikTok consumed 18% of the battery despite not being used.

Why? Because TikTok was refreshing content, downloading videos, and receiving live notifications in the background. Unlike a static app in suspension, TikTok maintains persistent connections and periodic downloads, which require active CPU and network usage.

This illustrates that the issue isn’t having apps in the background—it’s allowing resource-intensive apps to perform continuous tasks without oversight.

Practical Steps to Reduce Battery Drain

If manually closing apps won’t help, what should you do instead? Focus on controlling the actual sources of battery consumption. Here’s a step-by-step guide to optimize your device’s power usage:

1. Review Battery Usage Statistics: Go to Settings > Battery to see which apps are consuming the most power. Pay attention to both foreground and background usage percentages.
2. Limit Background App Refresh (iOS): Disable this feature for non-essential apps. Navigate to Settings > General > Background App Refresh and toggle off apps like games or shopping platforms.
3. Restrict Background Data (Android): On Android, go to Settings > Apps > [App Name] > Mobile Data & Wi-Fi and disable background data for apps that don’t need it.
4. Manage Location Permissions: Only allow precise location access for apps that truly need it (e.g., maps). Set others to “While Using” or “Approximate.”
5. Turn Off Push Email: Switch email fetch intervals to “Hourly” or “Manually” instead of “Push” to reduce constant syncing.
6. Use Built-in Battery Saver Modes: Enable Low Power Mode (iOS) or Battery Saver (Android) to automatically restrict background activity and visual effects.
7. Update Your Apps and OS: Developers regularly release updates that improve efficiency and fix battery-draining bugs.

Tip: Reboot your phone occasionally. This clears out any rogue processes or memory leaks that might be silently consuming resources.

Comparison: Myths vs. Reality

Myth	Reality
Swiping away apps saves battery	It often increases battery use due to app reload overhead
All background apps drain battery	Only apps performing active tasks (location, sync, refresh) cause drain
More RAM = better battery life	RAM usage itself doesn’t drain battery; active CPU/network use does
Closing apps improves performance	Modern OSes manage memory well; reopening apps slows performance temporarily
Battery-saving apps are effective	Most are redundant or misleading; built-in OS tools are superior

Frequently Asked Questions

Does keeping apps open in the background slow down my phone?

No, not in the way most people think. Having apps in the background uses RAM, but modern smartphones are designed to handle multiple suspended apps efficiently. Performance issues usually stem from too many active processes or insufficient storage space, not background apps themselves.

Should I restart my phone every day to save battery?

Daily restarts aren’t necessary, but doing so once a week can help clear temporary files, stop misbehaving apps, and reset network connections. It’s a good maintenance habit, though not a direct battery-saving tactic.

Do battery-saving modes really work?

Yes. Features like iOS Low Power Mode and Android Adaptive Battery learn your usage patterns and restrict background activity, animations, and syncing for infrequently used apps. Independent tests show these modes can extend battery life by 15–30% under typical use.

Expert Insight: What Engineers Say

Mobile engineers at major tech companies emphasize that user intervention is rarely needed for background app management. Instead, they advocate for smarter system-level controls.

“The average user shouldn’t worry about background apps. Our job is to make the system invisible—handling memory and power so you don’t have to.” — Sarah Kim, Senior Android Engineer at Google

This philosophy underpins the design of modern mobile OSes. Rather than relying on users to manually close apps, the system intelligently suspends, throttles, or terminates processes based on usage patterns, battery level, and thermal conditions.

Conclusion: Smart Habits Over Quick Fixes

The idea that turning off apps running in the background saves battery is largely a myth rooted in older smartphone technology. Today’s devices are engineered to manage background processes efficiently, making manual app closing unnecessary—and often counterproductive.

True battery optimization comes not from swiping apps away, but from understanding how apps behave, adjusting permissions, and leveraging built-in system tools. By focusing on high-drain activities like location tracking, background refresh, and push notifications, you can achieve meaningful improvements in battery life without sacrificing convenience.

Instead of chasing myths, adopt habits that align with how modern smartphones actually work. Monitor your battery usage, disable background tasks for non-essential apps, and trust the operating system to handle the rest. These small, informed actions will deliver better results than any ritual of app-swiping ever could.
