Closing Apps Doesn't Help Battery Life

It is a common misconception that closing apps from Multitasking Center helps your battery life, for the most part. Craig Federighi from Apple responded to a customer email on Tim Cook's behalf putting this rumor to rest. While many might believe this is Apple bragging, there is definitive evidence that closing apps doesn't help your battery life, although not by much. Apps can be put into three different states: active, background, and suspended. There are a few other states, but they aren't relevant in this situation. Active is the one that uses battery and only occurs when you are actively using it. The background state is when you close the app. It stays in this state for a few seconds. Background state also occurs for apps downloading in the background, playing music, tracking location, or something along those lines. Finally, there's suspended, which occurs after background if the app isn't reopened. Here's the thing, closing an app takes the app out of suspended and puts it into active for a short period of time. In addition to that, opening that app again will require more horsepower, effectively using more battery. Yes, I know that's not a significant impact and yes, I know there are exceptions (*cough* *cough* Facebook), but technically speaking, you are better off not closing your apps. Anyways, I didn't want to go all Vsauce on this post, but I just had to get that out.
