Debunked Myths

Myth:
Closing all background apps saves phone battery and makes it faster.

The Truth Is:

Force-closing apps actually **wastes** battery and makes your phone work harder when you reopen them.

What We Know Now:

This deeply satisfying ritual—swiping away a dozen open apps—is the modern equivalent of shaking a magic 8-ball: it *feels* like you're optimizing something, but you're actually doing harm. The myth comes from the early smartphone days when systems were clumsy. Now, your iPhone or Android keeps idle apps frozen in a low-power state, like they’re sleeping politely in the back room.

When you force-close an app, you're not putting it to sleep; you’re **killing** it. The next time you open it, the system has to perform a full, energy-intensive restart, loading everything from scratch. Keeping them sleeping, however, means the phone can wake them instantly with minimal energy. The only time to close an app is if it's genuinely frozen or malfunctioning.

This myth is a perfect example of our desire to micromanage technology, believing we're smarter than the sophisticated operating system running the show. The true 'aha!' moment is realizing that the phone manufacturer designed the system to manage power better than your anxious swiping ever could.
