Most of the wireless body area networking (WBAN) nodes are battery-operated, and cannot be used indiscriminately because the batteries have limited energy sources. In this context, this paper presents the Battery friendly Data Delivery Strategies for WBAN named bfdWBAN in order to upload the large data(e.g. image and video files) created by WBAN nodes to back-end web server. In the beginning, according to the analytical battery model, we conclude the battery recovery effect and non-linearity effect, and then find the upper bound time to recover at least 60% of the unavailable charge. Secondly, on the basis of the battery non-linearity effect, we split the large data into multiple smaller pieces and transfer pieces in a non-increasing operating current which is friendly to extend battery lifetime. Finally, according to the battery recovery effect, the restore time is inserted when uploading piece failed, that is friendly to battery, and the battery performance is improved. Our resul
