The study, conducted by a team lead by Abhinav Pathak from Purdue University, analyzed the energy used by several popular free Android apps (PDF) like Angry Birds, Facebook, the New York Times, and Chess. The team developed an "energy profiler" they call "Eprof" that determines what processes within an app are using energy. The results are shocking: 65 to 75 percent of energy consumed by the free apps studied are used by third-party advertising modules within the programs. These apps continue to run in the background even when you're not actually using the app. Only 10 to 30 percent of that energy is used to power the applications' "core functions."
Apps shouldn't continue to serve you ads when you're not locking at the apps. It's a bug, or something more nefarious. According to the researchers, developers don't notice energy consumption problems—bugs or otherwise—because most apps are "energy oblivious," meaning that the developers don't pay attention to how much energy apps use.

That's interesting news although I was sure that apps already did drain battery, I guess the energy consumption part just isn't that important to some.
Now thats why my phone's battery drains at a quick rate. Interesting study, app devs need to start looking into their app's power consumption.
good info
Wow, I figured that the ads drained a bit of battery, certainly not that much though!
