A researcher in the US has developed a new smartphone app that can help you minimise energy consumption and extend the battery life of your cell phone.
Y Charlie Hu, a professor in the Purdue University school of electrical and computer engineering, has created the app named Estar that shows how quickly other apps will drain a smartphone battery, and offers energy efficient alternatives.
"We created the free Estar app specifically to empower smartphone users to extend their smartphone battery life by exposing energy footprints of all the popular apps in the app market," Hu was quoted as saying by The Journal & Courier.
The app provides users with information so they can make more informed decisions on whether they want to avoid downloading power-hungry apps or remove such apps that were previously downloaded.
