Does it REALLY save battery life?

[maemer]

A friend that just got her iPhone5 last week was told that if she tapped the home button twice....then held her finger on an app that appears at the bottom of the screen...then tap the minus sign to turn the app off...that this would save her battery....does it?

Not really. Often times, it takes more resources to reboot the app after deleting it from your multitasking than to just leave it cached in the background.

willerz2 is spot on. "Killing apps" in iOS is basically wasting battery life, not saving it. The people that recommend that are either ex-android users, where that used to be needed prior to Android 2.3.x, or they are people that read that it used to help with Android and they think it applies to iOS since both OSes are *nix based.

Should mention, there is a very valid reason to "kill" an app. But it has to do with memory issues not battery. Sometimes apps can get "stuck" with bad data due to a crash. When that happens, it may be nessecary to tell iOS to "start over" and load the app from disk instead of from memory. Killing the app does just that. And that is the reason the feature was added to iOS.
