Researchers, including those of Indian-origin, have developed a software that can significantly reduce the battery drainage in smartphones by intelligently suppressing apps that run in the background.

The software got here out of a large-scale research of two, 000 Samsung Galaxy S3 and S4 telephones customers, served by 191 cellular operators in 61 nations.
They have made a new tool, free Hush tool, that lets only the most-used apps check in while the phone is off. Hush can cut power loss from the apps by nearly half.
“During screen-off, the phone hardware should enter the sleep state, draining close to zero power”, Hu says.
“Out of the 45.9 per cent of daily battery drain where the screen is off, 28.9 per cent is due to apps that frequently wake up and run in the background”, the university’s release claims.
To elucidate further, Mr. Hu stated that software bugs and incorrect use of the power control applications that are known as wake-locks interfere with the system causing power leakage. Hu said that by doing this, the phone can save 16 percent of its battery life.
“Being able to reduce the total daily energy drain by about 16 percent is rather significant because you can extend the battery charge by one-sixth”, Hu says. To prevent turning off useful functions, the app learns which apps and what functions the user frequently accesses – such as checking Facebook news feeds – and takes these factors into the equation.
The team will present their findings this week at the ACM MobiCom 2015 conference in Paris.
The HUSH system dynamically identifies app background activities that are not useful to the user experience on a per-app basis and suppresses such background app activities during screen-off to reduce the battery drain.
To do this, his team plans to look at other battery-drainers on your phone.

Hu targets to extend the battery life of all smartphones by double what users are enjoying now, with the development of HUSH the first step in what he describes as a non-trivial journey. “The opposite shock from the in-the-wild research was that about 18.5 per cent of the day by day battery drain occurs from so referred to as upkeep actions together with periodic WiFi beacons, WiFi scanning, and Mobile Paging”, he says. About 46 percent of battery drain can be attributed to these apps, especially when the screen is off.
