I had earlier thought of marking it as a duplicate of the question you linked in the flag but stopped because his case is of data usage per se, not of battery usage. Although the answer may be same for both of them.
There is a mysterious app, 99070 that is consuming power on my Nexus 5X. Any idea how I determine what it is?
There is no option to stop or uninstall it. My phone is a Nexus 5X running stock Android 6.0.
