Ad-supported apps in Android smartphones are an immense energy suck.
According to a Purdue University study (PDF), which—interestingly enough—Microsoft helped research, third-party advertising in free Android apps deplete 65 percent to 75 percent of an app’s energy. The study said more than 50 percent of energy used for serving ads occurs during the “3G Tail.” In other words, energy continues to dole out after the process requiring power completes.
The researchers analyzed the energy squandering of 21 Android and Windows Mobile apps over a 3G connection, but the study only highlighted five Android apps (Angry Birds, the Android default browser, Chess Free, MapQuest, and The New York Times).
