Can’t clear RAM on iPhone 15 pro max

[DeanL]

Probably bad habits picked up over the years. I was at a birthday party last weekend, and I saw a girl who had the 14PM and she was constantly kicking apps out of memory. That triggers me so bad, lol. Just ignorance.

I used to think like you, but noticed real difference in battery life by kicking apps out.

It's been demonstrated over the years that apps can use various tricks to wake themselves up in the background–through notifications for example (whether silent or visible).

There used to be an argument that kicking apps out of memory consumes more battery because the app has to load again, but everyone knows that iOS is aggressive with memory, meaning that a lot of apps get kicked anyway. If they are still in the app drawer, they can wake themselves up, but if they aren't, they shouldn't be able to.
The other thing is that iPhones are so fast nowadays that it probably doesn't consume that much energy to loads app again.

In any case, I think a lot of apps are playing dirty without Apple noticing or paying attention. If Apple provided an Activity monitor for iOS, people (at least power users) would be able to accurately monitor the usage of apps and make appropriate decisions.

For years it was to clear the RAM

There's no real reason to do this. What are you trying to accomplish?

 

[Cruncher]

This is a system status app, not a RAM clearer, or anything useful by all accounts.

The only way to clear RAM on iPhone is to restart the device.

That`s true. But when you click on RAM it will clear the RAM Cache automatically.

I see this all the time with those that I'm acquainted with that have an iPhone.. I ask them why. They claim that it extends battery life because the apps would otherwise just continue to run in the background as if they were at the front.

These people have the idea that they are dealing with a desktop computer OS like Windows, as most that are in my age group, are brought up with using Windows computers and loathing Mac computers.

I tell them to try and let the OS handle the apps such as Rejseplanen (a traveling app) that can then be allowed to track bus departures better than if the application is quit with each use.

There are many people in here in Denmark and I'm guessing around the world who doesn't know that iOS is updated and optimized to handle memory and efficiency of apps.

Despite all willingness to help these friends and acquaintances along and probably have their iPhone experience be better, they continue to claim that "I'll just do what I always do and ain't no nerd is gonna tell me otherwise" "Do you even know" I tell them, that I don't know and they must be right. It's their iPhone after all.

I am no angel and I am known do quit apps in iOS when they have a weird behavior.

I must have been oblivious to this fact. Thank you for writing about it. I could see many of the social media apps being poor iOS citizens.

There are some apps that are poor iOS citizens indeed, mainly social media. One very specific example is Snapchat sometimes "hanging" in the background after using it, and racking up background usage in the battery statistics (and also creating a slight drain). My habit is to just kill off those apps that are known to have such bugs. I leave the others alone (and I for sure don't do any weird "clear entire RAM" dances as that makes absolutely no sense).
