Abstract: Smartphones and smartphone apps have undergone an explosive growth in the past decade. However, smartphone battery
technology hasn’t been able to keep pace with the rapid growth of the capacity and the functionality of devices and apps. As a result,
battery has always been a bottleneck of a user’s daily experience of smartphones. An accurate estimation of the remaining battery life
could tremendously help the user to schedule their activities and use their smartphones more efficiently. Existing studies on battery life
prediction have been primitive due to the lack of real-world smartphone usage data at scale. This paper presents a novel method that uses
the state-of-the-art machine learning models for battery life prediction, based on comprehensive and real-time usage traces collected from
smartphones. The method is evaluated using a dataset collected from 51 users for 21 months, which covers comprehensive and fine-
grained smartphone usage traces including system status, sensor indicators, system events, and app status. We find that the battery life of a
