How to access app switcher(clear apps running) on the new iPhone SE 2020?

See these instructions:

Switch apps on your iPhone, iPad, or iPod touch - Apple Support

Note that those are not running apps. They are recently used apps. There is no technical reason or benefit to remove them from recents unless a specific app is causing you a problem.

I just got an answer from a higher authority. They think you may be double-touching the HOME button rather than double PRESSING it. Double-touching opens Reachability.

See this LINK for information on the apps in the app switcher (WHICH ARE NOT RUNNING)

The apps are NOT running in the background (except for a few exceptions). They are in a suspended state. You will gain nothing by removing them from Recents (force closing them) except possibly to use more battery life. But, if you really must, use the instructions I linked to.

That is the Reachability view. It moves the screen down so you can reach the icons at the top. It is activated on most phones by double-tapping the screen. So apparently the SE2 uses a different method. I haven’t been able to find what it is, and I don’t have one so I can’t experiment. But for the X and later you swipe up from the bottom of the screen and pause halfway up. You might try that.

As you have been told several times, the app switcher DOES NOT SHOW RUNNING APPS. It only shows apps that you have used recently. NONE OF THEM ARE RUNNING, and there is never a reason to kill them unless they stop working. Killing then INCREASES battery drain and slows down your phone. So until you find out how to access it on an SE 2 don’t worry about it.

Thanks, but I needed to close an app (TuneIn radio) which continued to play in the background (which is fine when I want it to!) and until I saw these answers, the only way out was to switch off the phone and restart it.

A fair point indeed, but I am new to smartphones (the SE 2020 is my first and I am still expecting it to be identical to my iPad Pro!) and it happened at a particularly inopportune moment so I sort of panicked!

I now know for the future. :-)

You aren't likely to hurt anything by force closing an app. So, it's a fair move if you're panicking! And, in the event the app is misbehaving, it's an important option.

The reason you don't want to make a habit of it is because the device will use more system resources completely restarting an app than in unsuspending one.

Yes, and I provided a link above with instructions on how to access that. Did you click on it?

While it should, the last time I looked at the TuneIn app while you could pause it, the app would resume on its own sometimes.

It should stop playing if you tap pause within the app.
