My son has has asked me:

My iPad is getting slower and slower to the extent that it’s making some applications difficult to use. I could try shutting down or restarting but my perception is this is a recurring issue. Is there any known memory or process monitoring on the iPad to see if I have an app that is misbehaving?

I know of none, but that doesn't mean there isn't anything. cAnd if there is I assume it would apply equally to the iPd and iPhone.

Any suggestions? I have suggested a power down and restart, and he will try that for starters.

Old John.

You could try if closing all running apps helps. (AFAIK a restart won´t do that).

iPad OS SHOULD take care of memory by itself, but I have encountered some situations where closing all apps helped.

The problem with devices is that most people don't close (and don't
know how or that they should) apps they aren't currently using, so they
can end up with lots of stuff still running. It doesn't matter whether
it's MacOS, Windows, iPadOS / iOS, Android, etc.

The same happens with things like web browser tabs. People just leave
them open whenever the browser opens a new one.

All these open things chew through RAM, and when that runs out the OS
can often swap them out to storage drive space, clogging that up as
well.

There should really be a system preference option set by default for
novice users that properly closes apps / tabs that haven't been used in
a while and arent doing anything (such as playing background music).
That alone could solve a lot of "it's slow" problems.

My thanks to you all. I have passed it all on, and Julian says he will go through it systematically and let me know what happens.
He is fairly new to the iPad and iMac, having inherited Anne's. I have recommended that he try the last suggestion first - I am reminded that Anne
was prone to this; she sometimes came to me complaining that she couldn't open such and such a link in Safari. I would find that the poor app was chock full of tabs (many of them duplicates) and could't open any more.

Why didn't she use the "Kill Switch" (Force Quit)?

LOL. It sucks on all OSs except iOS/iPadOS.
You have absolutely no clue. Nothing new.

No, restarting does close all apps.

Many people have the mistaken impression that manually force quitting
iOS apps is a good thing to do, but in reality force quitting apps makes
the device work harder and use more battery the next time those apps are
used. The OS manages apps in a much more efficient manner than you can.
The only reason you should be thinking about force quitting apps is if
you are troubleshooting a problem.

The operating system that runs on Apple’s mobile devices automatically suspends apps when you switch away from them, and automatically resumes
them when you switch back to them later. Suspended apps do not use CPU
or battery while suspended. Only a few certain types of apps are allowed
to run in the background in iOS, and only on a limited basis.

Apps can exist in any of five states of execution:

- not running: the app has been terminated or has not been launched
since the device was restarted
- inactive: the app is in the foreground but not receiving events (for
example, the user has locked the device with the app active)
- active: the normal state of an app while in use
- background: the app is no longer front-most but is still executing code
- suspended: the app is still resident in memory but is not executing
code

When you switch away from an app, the OS moves the app from active to background state. Most apps usually then go from background to suspended
in a matter of seconds. Suspended apps remain in the device’s memory temporarily so they can resume more quickly if you switch back to them;
but they aren't using processor time and they’re not sucking battery
power.

If you launch a memory-intensive app, such as a game, the OS will
automatically purge some suspended apps from memory and move them to the
not running state to free up memory for the memory-intensive app you
launched. Those previously suspended apps will be completely removed
from memory and will launch from scratch the next time you tap their
icon. Well-written apps automatically save their state before they are suspended and restore it when they are launched again.

Most apps do not run in the background. The OS gives all apps a default
five seconds after you switch from them to wrap up operations in
preparation for being suspended. After this five-second period, the OS automatically suspends the app’s operations.

If an app developer believes they need further background processing
time, they can design the app to declare a specific task as background
task which allows the task to run for up to about ten minutes of
background running time before it is forcibly suspended by the OS.

So all apps get five seconds of background execution allowing them to
clean things up when you switch away from them. And some apps can
request a ten-minute extension for longer processing tasks. But there
are a small number of apps that genuinely need to run in the background,
either indefinitely or periodically.

The OS restricts this indefinite/periodic background activity to exactly
five kinds of apps:

- apps that play audio while in the background state
- apps that track your location in the background (for instance a
turn-by-turn GPS navigation app needs to be able to give you voice
prompts even if another app is active)
- apps that listen for incoming voice-over-IP (VOIP) calls (for instance
Skype needs to be able to receive incoming calls while the app is in
the background)
- apps that you allow to refresh their data in Settings > General >
Background App Refresh
- apps that receive continuous updates from an external accessory in the
background

Generally you already know if you are using one of these types of apps.
And all well-written apps in the above categories become suspended when
they are no longer performing the task at hand.

iPad OS SHOULD take care of memory by itself, but I have encountered some situations where closing all apps helped.

Force quitting a particular misbehaving app may solve a particular
problem, yes. But force quitting all apps on a regular basis isn't
necessary and does more harm than good.

Well ...

Suddenly my battery was draining very quickly and I had no idea why.

Turns out I had unintentionally left a sensor recorder running in
background and (at 5Hz and many parameters) that burned the battery
pretty quick.

The very helpful Battery status app (Settings) showed me which app was
the bad boy. And I turned off the recording - no need to kick the app out.

To be sure the fault was mine.

But this was a case where a "precautionary kick out" of an app would
have saved me a little frustration.

Otherwise I rarely deliberately kick apps out.
