There are a lot of rumors and errors about the iOS system that are circulated by many, but there is one wrong information that is more widespread than others, and you rarely find a user who knows that it is wrong information and not correct, and it is ...

The applications on the multitasking bar continue to work and is considered an excessive pressure on the device’s processor, which leads to an increase in its work and thus increased battery consumption, and to ensure the efficiency of the operation of your device Close these applications

Isn't that what we all know? Well, surprisingly, this information is completely wrong.

I know that you will object at the beginning and say this is what our parents told us, and do not blame you, as all operating systems that I dealt with previously considered this information correct in it, but not with the iOS system, and I will prove to you by evidence the truth of my words.

We all know that the iPhone, iPad, Father and D Touch works with the strongest operating system and the most advanced operating system in the world, which is iOS, and this did not come out of thin air, but because Apple studied all the problems facing other operating systems and addressed them in its system, and the most famous of these defects is the slowdown of the device due to its fullness Memory, which also leads to excessive battery consumption, and other companies failed to deal with this matter, especially Android, and resorted to the other solution, which is to increase the memory capacity, processor speed and battery size, for example the size of the iPhone's memory is only 512 MB, whether the iPhone 4 or 4S, while you will find most of the competing phones with Android have a memory 1 GB, and also a dual-core iPhone processor 1 GB versus 1.4 dual-core in the case of the Samsung Note, as well as the iPhone battery 1420 mAh versus 2500 mAh per note, despite the difference in capabilities is very clear, but in the case of using the two phones and opening more than one large application, you will find that it There is no little difference in speed if the iPhone is not faster (which is fixed by numbers) and the reason is always as we repeat it is Apple's good management of the device's resources, and let's see how Apple manages its device's resources. This is evident in various studies and statistics

Before we begin with the explanation, you must know a very important information.Multitasking in iOS does not contain the list of currently running apps but rather the most recently used apps“I hope that this information is clear, and it must be clarified that the application modes in iOS are only 5 modes only:

  1. Currently running application.
  2. The application is completely closed or not opened.
  3. Application running in locked screen mode (I launched an application and pressed the power button once to close the screen).
  4. An application that works in the background and consumes the power of the processor and its memory, but does not appear on the screen.
  5. An application that does not run in the background and does not consume processor power, but reserves part of the memory.

These are the only 5 situations that there is no other, and we will now clarify what the previous situations mean, and of course Situations No. 1 and 2 are known to everyone and do not need any clarification.

When you press the (home) phone button, the application immediately moves from the active mode (working) to the background, and this command takes a few seconds for most applications (exactly 5 seconds). We know it and the work mode that we also know, this mode is characterized by allowing you to return to the application quickly and find the application still in the same position that you left it in a few seconds without waiting to download the application again. But In this mode the application consumption is from the processor zero But it only occupies a portion of the memory, but the processor consumption, as we said, is zero does not work The processor is overloaded and thus also has zero power consumption.

Background applications

Well, you might say that now we have proven that applications (suspended from multitasking) do not run the processor completely, and this does not lead to power consumption, but occupies part of the memory, which leads to the fullness of memory and slow the device to run new applications. Yes what you say is correct but not with iOS. Apple has studied this situation and developed two solutions for it ... the first It is if you do not use the application for a long time, then the system automatically closes the application permanently from the memory even if it remains visible in the multitasking bar ... The second The memory is full, for example, the memory of your device was 512 MB and you opened the 100 MB application and then left it (and it kept 100 MB of memory), then applied 250 MB and then applied 100 MB, now the occupied percentage has reached only 450 MB, well what happens if you run an application Another 100 mega? What happens is that the system automatically closes open applications in order to provide the new application the space it needs in a few seconds, and the applications that have been closed and removed from memory will remain in the multitasking bar because as we mentioned above (it contains the last used applications and not the last active applications) and when you open An old application you will find that it starts again, and to believe what I say, hold your device and open a large game, then play with it for a few seconds, then move to another and so on, and so on, for example, to reach 5 games and now go back to the first game and you will find that it opens from the beginning as if it was completely closed. This is the interpretation of the third and fourth situation.

The application works in the background

Well what is the fifth position? For example, when you open an application and you want from within this application to download a video, for example, and you see that it needs 20 minutes to download, but you do not want to wait for 20 minutes, then you go to the Safari application, for example to browse the Internet, in this case the application is suspended But It works and consumes energy and memory because it downloads the video clip, but after the application finishes the task that it performs, and here downloading the video, it stops consuming energy and moves to the fourth position that was previously explained, and these types of applications are very few and you will find only a few on your device.

Conclusion:

  • The apps in the taskbar are not really running in the background but rather are the last apps you used
  • The applications in the taskbar do not consume anything from the processor, thus saving energy
  • The last used applications have part of the memory, and this even if you open it again does not work from the beginning, but rather from where it left off
  • Memory consumption does not affect energy and the memory is emptied as soon as another application needs it
  • Some applications, such as audio applications and downloading materials from the Internet, may consume the device’s processor, but a small portion and for a specific time
In the end, we would like to communicate information to you and you do not have to worry about the taskbar and its applications, and do not close every application you open from the taskbar, let your device work as it is ... I know that what consumes the most energy from your device is the jailbreak and its applications that do not take into account the conditions set by Apple.
Do you still not believe me? Don't believe iPhone Islam :) Okay This is a video His work was done by a Khawaja developer who does not know us and we do not know him who studied the matter professionally in detail and put the sure proof in a video ...
