Want the answers to questions about the iPhone? You'll find questions and answers here.
I know that some phones have an app that automatically turns off apps running in background with one key stroke or automatically every so often. Does anyone know if iPhone 5 has such an app?
The vast majority of apps cannot and do not run in the background. For more info on Multitasking...
Well I believe there is a need for one.
An app called SYS Activity Manager (and reportedly, other similar apps too) shows camera running in background.
I can receive emails, VoIP calls and texts, updates from my city's transit service app and they don't even show in the double tap menu. Some of them happen even without notification for them turned off. Lord knows how many other apps run like that.
So yes, for some of us who run their phones on something called "battery" and "wireless data", there is a serious NEED for viewing what apps are running in background and a way to pick and close them.
Your belief is completely incorrect, and you obviously have no understanding of how multi-tasking works on iOS devices.
Try reading and understanding: http://speirs.org/blog/2012/1/2/misconceptions-about-ios-multitasking.html
hah. I may have little understanding how this works (Level 1 for a reason) but I am really really sick and tired of getting referenced to that same kind of links.
Also, I wasn't even talking about multi-tasking bar. I need a way to close apps that don't show up in multi-tasking bar but still uses RAM and battery power.
Well, you can't and you don't need to on iOS.
Only essential system processes/apps that are part of the OS can truly run in the background unhindered. The OS automatically handles these (sleeping, waking, killing and launching them as necessary) and there is no user accessible functionality for managing them.
If you want a mobile operating system where the user has to control system processes and background tasks manually, feel free to buy a mobile phone from 10 years ago. Mobile OSs have moved on since then, and such technical knowledge and manual control over such things is no longer required.
