It's always fun to hear directly from Apple execs, who often take to email or Twitter to offer short answers to questions from Apple customers. The latest comes via 9to5Mac reader "Caleb", who sent an email to Apple CEO Tim Cook asking about quitting multitasking apps in iOS:
The answer didn't come back from Cook; rather, it came from THE source, Apple's Senior Vice President of Software Engineering, Craig Federighi. The man with the best hair in tech came back with a succinct response:
I'm glad to see an Apple exec taking the time to put this myth to rest, as at least once every time I teach an iOS class I get this exact question. As 9to5Mac's Benjamin Mayo points out, "most of the apps are either frozen in RAM or not running them at all, the system just displays them as a history for consistency."
One thing I often suggest to my students is that if battery life is a concern, launching Settings and then going to Privacy > Location Services and setting most apps to "While Using" rather than "Always" will have more of an impact. Rather than constantly checking your location, only those apps that you actually have open and in use will take advantage of using GPS, Bluetooth, and crowd-sourced Wi-Fi hotspot and cell tower locations to determine your location.
