In the model used by Purdue University they found that 45.9% of your battery's charge is drained by apps which access resources while your screen is turned off and that 28.9% of that is because of bad programming in apps which refuse to let the CPU go back to sleep. Being able to prevent the launch of the apps, or to ensure that they do properly release resources when finished could therefore extend your battery life. They have modified Android framework to do so in this proof of concept available at GitHub, it is not an app yet so you will need to be familiar with the Android OS to test it out now. Check out the their paper at The Register, modify your phone or simply wait for the app to be released.
"Too many Android apps are battery hogs when the screen is off, so researchers at Purdue University have released to a tool to shut them up."

My Meizu MX4 Pro has a built app in that kills every app when the screen is turned off for 10 seconds, and you have to manually allow the apps to be run with the screen off. When i did not know this existed, it really bothered me that my audio would cut off every 10 seconds.

You must be talking about when I mentioned fact-checking. Fact-checking is when you read an article, you go and verify it. Typing in Perdue quickly reveals the typo. But hey, maybe I’m the only one who went to Purdue Owl for MLA and APA references like I did in college.
