It contains a list of recently used apps. The iOS multitasking bar does not contain a list of all running apps. To maximize performance and battery life, you should kill them all manually. Here’s the statement I keep hearing, and it’s wrong:Īll those apps in the multitasking bar on your iOS device is currently active and slowing it down, filling the device’s memory or using up your battery. It has to do with how multitasking works in iOS. Even supposedly authoritative sources such as Apple Geniuses don’t seem to get it. There’s one bit of iOS misinformation that I keep hearing. I’ve also bookmarked few articles from popular blogs about this. Apps that receive continuous updates from an external accessory.Īll those apps become suspended when the user stop using that kind of feature (the ones in the list) which enable unlimited background.Newsstand Apps which are downloading content. VOIP apps which are able to receive incoming calls even if that certain app is not running.Navigation Apps which uses the GPS module.There is actually few kind of apps which do run in the background indefinitely. When a low-memory condition occurs, the system may purge suspended apps without notice to make more space for the foreground app. While suspended, an app remains in memory but does not execute any code. The system moves apps to this state automatically and does not notify them before doing so. The app is in the background but is not executing code. For information about how to execute code while in the background, see “Background Execution and Multitasking.” In addition, an app being launched directly into the background enters this state instead of the inactive state. However, an app that requests extra execution time may remain in this state for a period of time. Most apps enter this state briefly on their way to being suspended. The app is in the background and executing code. This is the normal mode for foreground apps. The app is running in the foreground and is receiving events. (It may be executing other code though.) An app usually stays in this state only briefly as it transitions to a different state. The app is running in the foreground but is currently not receiving events. The app has not been launched or was running but was terminated by the system. Hanging around the developer section I found an interesting Guide for developers on this matter, I just quote an extract 2 : Here’s another interesting video about this matter, unfortunately, it’s only available in Italian, but it clearly shows that app running in the background are idle and they’re not sucking battery life, instead of when you manually kill an app the processor and so the battery is heavily used. These apps are not necessarily actively in use or open. Double-clicking the Home button displays a list of recently used apps. Certain tasks or services can continue to run in the background, and you can determine most by checking the status bar. Most applications are not taking up system resources when running in the background and instantly launch when you return to them. Multitasking doesn’t slow down the performance of the foreground app or drain battery life unnecessarily. Now let’s take a look at what Apple says on his website: It has its specific power management specific to avoid excessive battery usage, it also handles difficult memory situations automatically, it has built this way to provide a great experience where user have to care only about doing things, it’ll be on the OS then to decide when is the time to free some RAM.īefore you even start you should watch this video made by a developer on how multitasking works on iOs: IOs is a mobile OS and it doesn’t Behave as every other desktop OS that you’re used to using. When I talk about multitasking on iOs I see that many people are uninformed on this matter, even Apple geniuses.
