Swiping up to close apps on your iphone? you’re probably wasting battery
The common iphone habit
We’ve all been there: finishing up on Instagram or closing out of WhatsApp, and instinctively swiping up to force-close the app. It feels productive, a way to free up memory and extend battery life. But as Apple’s own engineering chief, Craig Federighi, recently demonstrated, this habit is largely counterproductive. He flatly stated he doesn't close apps to save battery, and for good reason: iOS doesn’t operate like Android or a traditional computer.
How ios manages apps differently
In systems like Android or Windows, leaving processes open can lead to a tangible drain on resources running in the background. iOS, however, takes a different approach. When you exit an app, it doesn't terminate it. Instead, it essentially freezes it in RAM, pausing it without consuming processor power, battery, or data. This allows for incredibly fast re-opening when you need it again; a deliberate design choice by Apple.
Why force-closing disrupts ios's efficiency
Manually closing apps disrupts this carefully crafted system. It removes the app completely from RAM, forcing the operating system to rebuild it from scratch the next time you open it. This involves loading the interface, retrieving data, and resetting the app's state – a process that uses significantly more energy than simply reactivating a paused app.
The battery drain paradox
The irony is that the very action intended to save battery actually consumes more. That initial startup surge is far more demanding than keeping an app suspended in memory. This highlights a fundamental misunderstanding of how iOS manages resources. While it might feel satisfying to clear the screen, you're likely doing more harm than good.
When background activity matters: permissions & settings
The real culprits of battery drain aren’t force-closed apps, but apps with specific permissions to run in the background. Think music apps streaming audio, Google Maps providing navigation, or messaging apps fetching notifications. To address this, Apple provides controls within Settings> General> Background App Refresh, allowing you to manage which apps can refresh content while not in use. This is where you should focus your efforts.
Exceptions to the rule: crashes & rare use cases
There are, of course, exceptions. If an app becomes unresponsive or crashes, force-closing it is the appropriate solution. Similarly, if you are absolutely certain you won't be needing an app for a considerable period, closing it is perfectly acceptable. However, for the vast majority of situations, that instinctive swipe-up is simply unnecessary and counterproductive. Let iOS manage your apps the way it was designed to.
