Extending the Battery Life of Smartphones and Tablets: A Practical Approach to Optimizing the LTE Network

A practical approach to optimizing the long-term evolution (LTE) network to extend the battery life of LTE devices such as smartphones and tablets is provided in this article. In cases where the battery consumption is not a major concern, the majority of the commercially deployed LTE networks are optimized for data dongles. Battery consumption has become a major bottleneck to the end user, with the introduction of LTE smartphones and tablets and other handheld LTE devices. The key relevant features and parameters that can potentially reduce the battery consumption and, hence, extend the device usage time, are analyzed, evaluated and validated in this article. Obtaining the optimum parameters setting for relevant LTE features to efficiently deliver non-real-time applications with bursty traffic over the LTE network by providing power savings without perceptibly degrading the user experience is the objective of this article. In order to identify the optimal deployment scenario for the most common data applications in a commercially deployed LTE network, along with the user inactivity timer (UIT), the connected and idle-mode discontinuous reception (DRX) mechanism are assessed and evaluated by means of field testing in a live LTE network.
