iPad Pro slow? (1 Viewer)

[Otter Spotter]

Over 6 years ago, Apple thought it was rubbish that users could have apps still running in the background hogging resources; so, in brief, they made apps stop running if they were closed.

But, realising that there are scenarios where a user could want background activity, they got app developers to incorporate a new "Background App Refresh" feature.
App developers using that can keep their apps running in the background but the users are prompted to accept or block that behaviour - usually when the app is first ran.
Or from the "Background App Refresh" settings area.

tl;dr
The closing of apps via the double home tap is now redundant
('cept for a frozen/locked app)
Of course, you also need to of adopted the "Background App Refresh" management.

You say that but why are the6 still there until you swipe them ?

Just cleared mine by the double tap method

? you mean when you double tap home to bring up the current and recent apps?
The recent apps aren't running. Just listed as recently used.
You can turn off & on the device and get the same recently used app list.

Some of the recently used apps can use resources in the background. But only if the user allows it via the "Background App Refresh" settings.
So swiping them off removes the tile AND stops resources being consumed.
OK? Did I understand and explain better your query?

That’s what I thought, I was told that the tiles slowed the pad down a bit like all the cache on a PC and it appears to work for me.

It's mostly just a habit iPhone learned from iOS versions before release 7.0
But if you have several apps with background refresh allowed then could still hit users, in theory.

I manage what apps are allowed access to background resources.

The question you need to look out for when launching an app for the first time are like "do you want this device to use location all the time, or just when in use, or never" and iirc there's one for "running in background".

In Settings "Location" is where you can revisit if an app can track you all the time, when app running (in use), or never.
In Settings "Background App Refresh" is where you can check how apps are behaving when you expect them to be stopped.
