There are people (including my children) who think that you have to swipe up all the apps in the app switcher every few hours so that the iPhone uses less power. The idea prevails that the iPhone “has to keep all the apps open”, which of course drains the battery.
No discussion of the sense and nonsense of deleting RAM
I would now deliberately not collect arguments for or against this theory, but simply assume that people want to delete the RAM on their iPhone or iPad every now and then.
Therefore, the following should also be about how to do it easily and not about how useful the thing is.
The check with the iPhone app "Usage"
The most important thing for me was that I had a way to check how full the memory was before and after the action. What use is the greatest trick if you haven't freed any data from RAM afterwards?
If you call up the app, you will find the RAM in the first “tile” and the “Free” item at the bottom of this area. That is, so to speak, the value that should increase through our action.
Back when iPhones and iPads still had home buttons, there was the following way to clear the RAM:
- Press and hold the standby button to go to the switch-off screen
- then press and hold the home button until the screen goes black
With this action, various buffers and the main memory were cleaned up.

Since the iPhone X, there is no longer a home button that you could use to complete the process above, which is why you have to look for a new way.
First I read that people conjure up a home button on their screen with the user guide and AssistiveTouch, but this technology does not help with clearing the working memory.
I've tried it and the Usage app unfortunately shows me no change in the amount of memory used.
Insider tip: start the camera app and "shoot" again immediately
I found the following trick in a YouTube video:
- you start the apple's own camera app
- Now swipe slowly upwards from the bottom of the display until the app switcher opens (in which you can see all the apps used)
- now you tap on the window of the camera app and swipe it up until it disappears
This opened the camera app and closed it again or "shot it down", as the saying goes.
Effect: almost 30% RAM free in 5 seconds
After my measurements with Usage, I was able to delete around 30% of the RAM on my iPhone 12 Pro Max each time. My iPhone model has 6 GB of RAM, but older and “smaller” iPhones often come with less memory. Unfortunately, I cannot say how many percent will be deleted here.
The fact is, however, that even by manually “shooting down” all apps, I couldn't get any more memory empty. So I would say that the camera app way is a pretty effective way to clean up memory.
