Smartphone battery not getting you through your workday? According to a Purdue University study published in conjunction with Microsoft Research approx. 65-75% of energy used in free apps is spent in third party advertising modules.
So if you’ve been wondering why your smartphone battery has been running down prematurely the answer could lay with the free apps you have installed and are running on your smartphone.
The study utilized a specially designed “energy profiler” (Eprof), on two mobile platforms, Android and Windows Mobile to detail how apps use energy by analyzing its power behavior.
