Michal Marek Although it is a pointless practice, it has become a rule for iOS device users to manually close all applications running on their iPhone or iPad. Most people think that double-pressing the Home button and closing apps manually will give them longer battery life or better device performance. Now, perhaps for the first time, an Apple employee has publicly commented on the topic, and that is the most famous one - the charismatic head of software, Craig Federighi.
Federighi responded by email to a question originally addressed to Tim Cook, which was sent to the Apple boss by user Caleb. He asked Cook whether iOS multitasking often involves closing apps manually and whether this is necessary for battery life. Federighi answered this very simply: "No and no."
Many users live under the belief that closing applications in the multitasking bar will prevent them from running in the background and thus save a lot of energy. But the opposite is true. The moment you close an app with the Home button, it's no longer running in the background, iOS freezes it and stores it in memory. Quitting the app completely clears it from RAM, so everything has to be reloaded into memory the next time you launch it. This uninstall and reload process is actually more difficult than leaving the app alone.
iOS is designed to make management as easy as possible from the user's point of view. When the system needs more operating memory, it automatically closes the oldest open application, instead of you having to monitor which application is taking up how much memory and manually close it. So, as Apple's official support page says, forcefully shutting down an application is available in case a specific application freezes or simply doesn't behave as it should.
Closing all of them is nonsense, the only ones I block are navigation and possibly some Skype-type chats, when I already had them installed, because the one in the background was burning the flashlight. I don't close the last one unless there is an error in the app. It doesn't even make sense.
So, now I would like to know how it is with Facebook, which is known to not respect these requirements and continues to run unnecessarily in the background.
End it manually or not?
Don't quit. Do not use. Uninstall. And if I need it by chance, I'll connect via Safari... ;)
HAAA, you nailed it beautifully! That's exactly how I do it, and my battery lasts until the next day completely undisturbed. As for the performance, it is true that it takes away from it to a certain extent. I didn't quit for a while and I got used to a certain speed and then I quit everything and it was a noticeable difference.
Well, or don't use the iPhone at all, go to an Internet cafe for information, and the battery will last even longer. ;-)
… well, just now I thought of Dynavix, Skype, etc. They really eat up performance in the background. And to be honest - rather than finding out what eats and what really "freezes", I sometimes prefer to turn them all off,... O:)
Terminating applications certainly makes sense, min. with FB, where when I started turning it off, I saved x-tens of MB.
The application runs in the background regardless of whether you have turned it off "hard" or just "put it in the background". If the app updates in the background, it's because it's enabled in the app's Background Update setting.
In the multitasking overview, most of the applications are already dead a long time ago and it's just a snapshot of the last state (unless you have the latest model with more RAM).
The savings count in that when the application turns them off "hard", Background fetch is no longer performed. So if you don't like the fact that you can see the current data when you start the application, you can disable this option in the application settings, you will avoid a sore thumb from shutting down applications, and in addition, some simple applications will start faster if they remain in memory.
What you see in the overview of running applications are usually only images of the last state of the application, the application itself is probably already dead... but it depends on the use of the system, if the active application claims large system resources, the system terminates inactive applications (stored in memory), so that the active one can go full speed.
I suspect that background fetch starts even after kill. at least that's how newstand mode works
It will definitely help to kill anything that somehow uses background processing https://developer.apple.com/library/ios/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/BackgroundExecution/BackgroundExecution.html
Many applications run in the background even after killing. it depends on what background mode it uses. e.g. apps that update the location in the background can do so even after killing
Oh yeah, I'm sick. Do I always honestly "kill" everything?
Facebook and Messenger -> since I kill these two apps, my battery lasts longer (I don't deal with the other apps). There was also an article about these two apps here on Jablíčkář, when the functionality that informs in the Settings which app runs for how long in the background and what percentage of the battery it consumes was shown.
agree with tomas. I don't have fb and mss on my phone anymore. how is it possible that I turn it off hard and in a while the icon shows 1, 2..? does it mean that it is always waiting, just like mail? and the application is probably written in the wrong way, because uninstalling it means getting to know a smaller sportreb.
