Force Quitting iOS Apps Decreases Battery Life
“My iPhone battery life is horrible, I keep closing all of apps but nothing seems to help. What should I do? When is Apple going to fix this problem?”
Stop closing the apps - that is the first thing you should do.
That’s right, stop quitting all of your apps to save battery life. Quitting iOS applications does not save battery life, it actually has an adverse effect. On a laptop, if you are running out of battery life, the first thing you do is close all of the applications that you are not using. Applications running in the background on a laptop is not something you want if you if you are trying to maximize your battery life. However, this logic can not be applied to iPhones. You can not use the same battery saving rules that you would for a Macbook running OSX and a iPhone running iOS. You have to remember that laptops and iPhones do not run the same operating systems, therefore they function differently.
Scott Loveless, a former Genius Bar technician, explains why:
“You are actually making your battery life worse if you do [close apps] on a regular basis. Let me tell you why.
By closing the app, you take the app out of the phone's RAM . While you think this may be what you want to do, it's not. When you open that same app again the next time you need it, your device has to load it back into memory all over again. All of that loading and unloading puts more stress on your device. Just leaving it alone. Plus, iOS closes apps automatically as it needs more memory, so you're doing something your device is already doing for you. You are meant to be the user of your device, not the janitor.
The truth is, those apps in your multitasking menu are not running in the background at all: iOS freezes them where you last left the app so that it's ready to go if you go back. Unless you have enabled Background App Refresh, your apps are not allowed to run in the background unless they are playing music, using location services, recording audio, or the sneakiest of them all: checking for incoming VOIP calls , like Skype. All of these exceptions, besides the latter, will put an icon next to your battery icon to alert you it is running in the background.”
We have been so use to having to clean, manage, troubleshoot, and fix our computers that we forget technology has advanced to a point where they are becoming smart enough to manage themselves. They are not perfect yet, but more often than not they run better without the user tweaking the settings.
