To solve this issue, we will need a net/qrtr[1] lib and a pd-mapper[2][3] program running in userspace in order to trigger the event required by the battery sensor (via QRTR/remoteproc) and its associated battery driver. I have temporarily packaged these two in my OBS home subject[4], and the result shows that the battery percentage can be fixed after running the pd-mapper. I will submit these two packages to the openSUSE network project.
