The destruction of the myths: whether it is necessary to remove the program from the multitasking bar on the iPhone and iPad?

Among iOS-gadgets users, there is a fairly firm conviction that unnecessary programs in multitasking bar better off. Allegedly, this will extend battery life, improve the performance of the device. The benefit of this approach say and the article by David Pogue in New York TimesAnd post in the US Lifehacker (Even the author laments the fact that iOS is not possible, as the quit all, which would turn off all programs). However, if this is so?
As it turns out, is the use of in order to regularly remove the application from the bar multitasking, no. Good technical justification for giving Fraser Spears.
According to Fraser, iOS-app can be in one of five states:
- is not running. The program was forced to shut down or does never run
- not active. The program is in the foreground, but does not receive any events (eg, the user has locked the iPhone with the active application)
- actively. Normal state of the program when it is currently in use (for example, a user playing Angry Birds)
- background. The program is no longer represented on the screen, but it still performs some code (for example, the player plays music while you're reading this book).
- suspended. The program is in memory, but does not execute code.
When the user clicks the Home button, the program from the active state into the background, and then automatically transferred to the suspended state. In the paused state, the application does not use the processor and does not drain the battery (but is in memory).
The program may request the iOS additional ten minutes to, while in the background to complete some task (download a file, for example). Then she goes into a suspended state. When some other program that is active, requires more memory, iOS automatically translates suspended applications to the status of "not neglect".
Once again, the system automatically suspends the background applications and then automatically exits the suspended programs to free up memory. That is Apple's approach. Steve Jobs questioned not only the stylus, but the task manager, you do remember that? :-)
how notes John Gruber, author of the blog Daring Fireball, multitasking bar is more reminiscent of the history of visited sites in the browser. If you do restart the iPhone will be the same applications in the multitasking bar before. It's just a story to run the program.
So it seems there is no need to waste time to regularly "clean" multitasking bar from the "old" applications. And you remove a program from the panel?
