A recent study at Purdue
University revealed some

As it turns out, as much as 75 percent of the energy
consumed by free Android applications is actually spent serving ads or tracking
and uploading user data for marketers. Popular apps like the free version of
Angry Birds or the NYTimes were shown to only use about 10-30 percent of their
energy consumption to actually power their core functions.
All this means that running a single free app can completely
drain the battery of some smartphones in approximately 90 minutes.
This discovery was made my computer scientists at the
university as they were developing a software to analyze the energy usage of
different applications. A lot of the energy being used in some of that apps was
for things like finding and uploading the user’s location with a GPS to send
them location-based ads via a 3G connection.
Much of the energy consumption is blamed on inefficient third-party
code that developers include in free apps to turn some kind of profit from
