WEST LAFAYETTE, Ind.  – A Purdue technology shown to extend battery life of digital devices has received federal funding to further develop the technology that could impact billions of devices including smartphones, notebooks and smartwatches across the world.

Mobile Enerlytics LLC was awarded a National Science Foundation SBIR Phase II grant of $749,998 to develop the mobile app industry’s first energy management solution to help app developers reduce battery drain, thereby, extending smartphone battery life for users. The company is based in the Purdue Research Park of West Lafayette, Indiana.

According to App Annie, annual revenue in the mobile app industry is expected to more than double to $139.1 billion by 2021.

“While the number of apps is growing, digital device battery technology has barely advanced in the past decade,” said Y. Charlie Hu, CEO and co-founder of Mobile Enerlytics and professor of electrical and computer engineering in Purdue’s School of Electrical and Computer Engineering. “It will become increasingly important to manage battery use as more and more apps become available.”

The funding will help Mobile Enerlytics develop advanced capabilities of the company’s Eagle end-to-end app energy management solution, the first technology of its kind.

“Eagle is an app energy management solution that tests, profiles and monitors apps for their energy draining properties in a continuous feedback loop from initial app development through user installation and running on their phones for each and every app release,” he said.

The technology is designed to seamlessly integrate into industry standard Continuous Integration app development workflow, which allows teams of developers to effectively build complex, feature-rich mobile apps.

Mobile Enerlytics also developed Estar, a free, no-adds app that shows users how fast different apps on their smartphones are draining their batteries. The app has more than 100,000 downloads from Google Play.

"When a smartphone user starts Estar, it provides two options: to find energy-efficient apps or to stop power-hungry apps running on the phone," Hu said.
