New Tool Increases Battery Life Of Phones By 16%

By -

Smart phones have one defect, short battery life. The good new is that scientists have developed an implement that can sufficiently fix this problem. It is called HUSH, the code monitors background app which activities and turns them off when they are not needed.

Contributed for this are Purdue University, Intel and Mobile Enerlytics. They involved the study of 2,000 Samsung Galaxy S3 and S4 smartphones on 191 mobile operators in 61 countries.

HUSH is a piece of coding for the operating system, not yet an app. It was developed for Android phones and can be downloaded on Github. Researches showed that it can save 15.7% of phone battery – about a sixth of daily use.

Other programs like this, such as Doze, are available. The research is the “first large-scale study of smartphone energy drain ‘in the wild,’ or in everyday use by consumers” , said co autor Y.Charlie Hu, a Purdue professor of electrical and computer engineering.

Usually, apps drain about 28.9% of battery power while  a phone’s screen is off. “Apps wake the phone up periodically during screen-off to do useful things, but then afterward, they should let the phone go back to sleep. They are not letting the phone go back to sleep because of software bugs and, specifically, due to the incorrect use of Android power control application programming interfaces called wakelocks”, explained Hu.

HUSH works by identifying background app activities that are not useful to a particular user. It is like Facebook updates for those who rarely check them, and supresses them while the screen is off. That is how it reduce battery drain. Also, researchers are working on ways to reduce energy drain from regular communication needs (or talk to a cellular base station every 1.28 seconds to check for calls and data; phones typically send a signal to a Wi-Fi beacon every 200 milliseconds).

Researchers are working to release an app version as soon as possible. Also, you can get to grips with a bit of basic coding if you want to make use of HUSH at the moment.
