That's why you don't have to worry too much about closing background apps on iOS

Do you really need to close all open applications in the background on iPhone, iPod and iPad? Is it really necessary to manually close all open programs in the background on Apple devices? It is a question that users have been asking for a long time and today we are trying to give a definitive answer on the matter.

As we all know, iPhone, iPod and iPad use Apple's iOS 7 operating system, which was developed to better manage multiple open applications simultaneously. The system allows you to open many programs and, with a double press on the home button, users can quickly recall the program of their interest thanks to the large tabs that allow you to manage the multitasking. All these open applications, however, in the long run go to fill the RAM of the iPhone, iPod and iPad and consume resources and battery. This is why users usually prefer to close them manually, one by one.

But is it really necessary to do all this? Apparently the negative answer. iOS was in fact designed to manage the best and independently apps open in the background. This way the system knows exactly when to close a particular application to free up processor and memory.

In support of this theory there is this interesting article written by the developerHarlan Haskinsand, which explains why you don't have to worry too much about manually closing apps inbackgroundin iOS.A large number of users doperiodically doubleclickon the home button to carry out themanual closure of various applications on iPhone, iPod and iPad,but this apparently is not necessary.

The reason? Simple: iOS 7 designed to automatically close apps that consume too much memory or processor when the smartphone needs it. In practice, the device leaves all the apps open until the RAM memory becomes too little. At this point, it automatically closes apps that consume too many resources. Apparently, therefore, the function of "background "it is managed very well by iOS and does not require our intervention.

Theoperating systempresent on iPhones, iPods and iPadsin fact, it has all the necessary instructionsto ensure a good general functioning of the device, even when we have a myriad of applications open inbackground. As soon as the home button is pressed, which implies the automatic execution inbackgroundof the app previously used, iOS comes into play and starts questioning it.

The time has come to put things in order. Empty the memory you used previously and block, for now, all the actions in progress. If you are still downloading something from the web, then do it in the shortest possible time.

Should the app in question need tocontinuous updatessuch as, for example, geographic data, notificationspushor other,iOS will knock on its door promptly providing all the necessary instructionsmain memory is running out, iOS sends messages to all recently opened apps:

Guys, forgive me but I have to disturb you again. We are quite tight and, unfortunately, we must free up space!

If even after this important communication the space is not enough, iOS will give onelook atlist in which all the apps appearopenand starting from the last, I will begin kill (to close) automatically a sufficient number of apps in order to guarantee the normal performance of the activities.

Even if told in a playful tone, this is the relationship that iOS has with the applications open inbackground.

In reality all this is not exactly correct, because if iOS manages very well RAM and processor, the same cannot be said of the battery: leaving all these apps open in the background, the battery consumes faster, there is little to do.

The advice, therefore, the following: it is not essential to close the applications open in the background on the iPhone, iPod and iPad, but if you want to save battery and get to the end of the day you should close at least the heaviest ones.

I close the article with the reflection of an Italian developer who certainly knows the iOS 7 system well:

Harlan's analysis is correct, but unfortunately most of the apps are not very careful to respond to the messages of the operating system for cleaning the memory, and I tell you this from an iOS developer with a lot of experience. When the system starts killing apps it means that the device is already struggling and in any case only the bare minimum is killed to ensure acceptable phone operation.
