You’re staring at your iPhone, wondering where that podcast app went. Or maybe your phone feels a little "heavy," and you're convinced that having forty things open at once is the reason your battery is screaming for mercy. Honestly, we’ve all been there. You want to see everything you've got running, but if you’ve recently upgraded from an old model with a button to a shiny new iPhone 17 or 16, the "how-to" has changed.
Basically, seeing your open apps is about mastering the App Switcher. It’s that deck-of-cards view that lets you flick through your digital life.
But here’s the kicker: what you see in that list might not actually be "open" in the way you think it is.
how to see all open apps on iphone (The quick way)
If you have a modern iPhone—basically anything from the iPhone X all the way up to the latest iPhone 17 Pro—you don't have a Home button. To see your open apps, you need to perform a very specific gesture.
Swipe up from the bottom edge of the screen and pause in the middle.
Don't just flick it up fast, or you’ll just go back to the Home Screen. You have to drag your finger up, hold it for a heartbeat until you feel a tiny vibration (haptic feedback) or see the app windows shrink, and then let go. Boom. You’re in the App Switcher.
Now, if you’re rocking an iPhone SE or an older model like an iPhone 8, it’s a different story. You just double-click the Home button. Simple. Classic.
Once you’re in this view, you can swipe left and right to see every single app you’ve touched in the last... well, potentially the last few weeks. It’s a long list. You can tap any card to jump right back into that app exactly where you left off.
The "Bottom Bar" Shortcut
There is a faster way to cycle through apps without even opening the full switcher. See that thin horizontal line at the very bottom of your screen? If you swipe left or right directly on that bar, you can "flip" through your most recent apps like pages in a book. It’s incredibly fluid once you get the muscle memory down.
Why "Open" Doesn't Mean "Running"
This is where most people get it wrong. You see fifty apps in your switcher and think, "No wonder my phone is slow!"
Actually, Apple’s software (iOS) is a bit of a control freak. When you swipe away from an app, it doesn't keep running at full speed. It enters a state called "suspended." It’s basically frozen in your RAM (memory). It isn't using the processor, and it isn't sucking your battery dry. It's just sitting there, waiting for you to come back.
Apple’s Senior VP of Software Engineering, Craig Federighi, famously confirmed years ago that closing apps doesn't improve battery life. In fact, it can actually make it worse.
Think of it like a car. Leaving the engine idling (suspended) uses a tiny bit of fuel. But turning the engine off and restarting it (force-quitting and reopening) requires a big burst of energy. When you force-close an app, your iPhone has to reload every single asset from the storage to the RAM the next time you open it. That takes more CPU power than just "unfreezing" a suspended app.
When should you actually close them?
Is it ever okay to swipe an app up and away? Yes. But only in specific cases.
- The App is Glitching: If Instagram won't load your feed or the camera app is showing a black screen, kill it. Swiping it up forces it to restart fresh.
- Background Activity Hijackers: Some apps, like Waze or Google Maps, might keep your GPS active even when they're in the background. If you see a blue or green bubble around the time in the top corner of your screen, an app is actively using your location or mic. If you don't need it, swipe it away.
- Privacy: If you were looking at something... private... and you don't want a preview of it appearing next time you open the switcher in public, go ahead and flick it off.
Honestly, the only reason to "clean" your App Switcher is for your own mental clarity. If you hate the clutter, close them. Just don't do it thinking you're helping your battery.

Managing the "Invisible" Background Activity
If you're still worried about apps doing things behind your back, the App Switcher isn't actually the place to fix it. You want to look at Background App Refresh.
This is a setting that allows apps to fetch new data—like downloading new emails or updating your weather—while they're suspended. To find it, go to Settings > General > Background App Refresh.
You can turn this off entirely, or better yet, just toggle it off for apps that don't need it. Does that random tile-matching game need to update its "news" while you're sleeping? Probably not. Turning this off is a way more effective "pro move" than manually swiping away apps all day like a digital janitor.
The Secret "Back Tap" Trick
Did you know you can see your open apps by literally tapping the back of your phone? It's an accessibility feature that most people ignore.
- Open Settings.
- Tap Accessibility.
- Go to Touch, then scroll all the way down to Back Tap.
- Choose "Double Tap" or "Triple Tap" and set it to App Switcher.
Now, you can just tap the Apple logo on the back of your phone twice, and the App Switcher pops up. It’s great if you’re using a massive iPhone 17 Pro Max with one hand and can't quite reach the bottom comfortably.
Real-World Nuance: The RAM Myth
People often talk about "clearing RAM" on an iPhone. Here’s the truth: iOS is designed to use as much RAM as possible. Empty RAM is wasted RAM. If the system needs more memory for a heavy game, it will automatically kill the oldest suspended apps in your list to make room. You don't need to help it. It’s been optimized for this for nearly twenty years.
The list you see when you swipe up is more of a "history of recent activity" than a list of "things currently taxing the system." Treat it like a browser history, not a task manager.
What to do next
Now that you know how to see your open apps and—more importantly—when to leave them alone, take a second to audit your background settings. Go to Settings > General > Background App Refresh and kill the toggle for any app you haven't used in a month. Your battery will thank you much more than if you spent the afternoon swiping apps away in the switcher.
If you're still noticing a massive battery drain, check Settings > Battery to see which specific app is the culprit, rather than assuming it's the sheer number of apps you have "open."
