基于全面和实时的使用数据预测智能手机电池寿命

Predicting Smartphone Battery Life based on Comprehensive and Real-time Usage Data

Huoran Li, Xuanzhe Liu, Qiaozhu Mei

摘要:

智能手机和智能手机应用程序在过去十年中经历了爆炸性增长。然而,智能手机电池技术已经无法跟上智能手机和应用程序的容量和功能的快速增长。因此,电池一直是智能手机用户日常体验的瓶颈。对剩余电池寿命的准确估计可以极大地帮助用户安排他们的活动并更有效地使用他们的智能手机。由于缺乏大规模的真实智能手机使用数据,现有的电池寿命预测研究还很原始。本文提出了一种新的方法,该方法使用最先进的机器学习模型进行电池寿命预测,基于从智能手机收集的全面和实时的【形】使用痕迹。所提出的方法是第一个识别和解决严重的数据缺失问题,在这种情况下,使用一个原则性的统计指标称为一致性指数。该方法使用从51名用户收集的21个月的数据集进行评估,该数据集涵盖了全面和细粒度的智能手机使用跟踪,包括系统状态,传感器指标,系统事件和应用程序状态。我们发现,智能手机的剩余电池寿命可以根据用户在实时的【形】、当前会话和历史中如何使用设备来准确预测。机器学习模型成功识别了电池寿命及其适用场景的预测功能。

英文摘要:

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 smartphones 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 proposed method is the first that identifies and addresses the severe data missing problem in this context, using a principled statistical metric called the concordance index. 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 remaining battery life of a smartphone can be accurately predicted based on how the user uses the device at the real-time, in the current session, and in history. The machine learning models successfully identify predictive features for battery life and their applicable scenarios.
