life goes missing on a smartphone? In the worst scenario, even if you
are a task killing ninja, there seems to be a list of applications that
take away all your battery life. Even when your phone is asleep, there

that about 28.9 percentage of battery power is drained by apps when the
screen is off. Out of the 45.9 percentage of daily battery drain , 28.9
percentage occurs because of apps that frequently run in the
background. So according to a research report, a new tool called the HUSH that is developed by Purdue researchers, comes with an objective to solve this problem.
