When i stop running background apps in iphone, why it starts saving battery?

Inspirations and solutions will strike you if you meditate this issue longer

Because their not running anymore. Duh
The phone isn't wasting energy, or battery, to run more applications, therefore saving battery.

Each app on the iPhone requires RAM and CPU power as soon as you have openned the app.
If you do not completely close the app after using it, it will continue running in the background. Even when running minimized in the background the app still uses RAM and CPU power which requires more battery use to keep running. For example, if you leave Skype open in the background you will see your battery drain very quickly. Skype constantly tries to keep your connection to the servers active so the amount of resources does not change, even in the background.

Best practice to save battery power is to completely close programs after you are done using them.

With no apps running in the background, less processor power is used.

  • Which Apple app is perfect for saving battery? I recently bought an iPhone 5c and the battery dies extremely fast. I see a lot of apps but I think all it dose is just tell me what is using my battery usage at the moment. I want a app that actually saves battery by doing what it has to do save battery.
