Think of it this way, when you’re on your PC or Mac, you can have more than one window open at the same time, you’re basically doing more than one thing at the same time and so is the computer. But how does that relate to smartphones and what’s the big deal?
Multitasking on smartphones is different. It doesn’t have the luxuries of a 20-inch screen, a powerful CPU and tons of RAM. Smartphones have more or less all of that in a smaller handheld device; basically it’s smarter.
Multitasking on smartphones has been around for a while now. For example, iPhones apps save state and close. In Windows phones everything stays running. Android phones on the other hand let threads and processes run depending on their priority.
Multitasking can be the deciding factor when picking a smartphone operating system. Android devices have by far have the best multitasking capabilities. For example, if you’re using Google Play Music, the processes that allow the sound to come out of the speakers have a higher priority to stay running when you switch away from the app. Not all of it is running just the enough of it to keep the music playing. Other apps can be killed so you can decide which apps are running.
The best multitasking we have seen by far on smartphones is the processing capabilities on the new Samsung Galaxy S3 with the Pop-Up Play feature which allows you to watch a video in a small window while doing other tasks such as sending a text message or even playing a game. All we can say is that this is multitasking at its best.
