Nobody likes to fork over 99 cents for an app. Free is better, right? Not necessarily, according to a new study.
It turns out those free apps could be draining your phone's battery and your data plan. Researchers compared the paid and free versions of 21 top apps in the Google Play store. It turns out that the free versions on average used 16 percent more energy, 22 percent more memory and 79 percent more network data.
