Unknown Process killing my battery

[akxsh]

I am using an Oreo based Asus " Zenfone Max Pro M1 " .
Since I charged my phone to 100% and the battery is fully charged . After 3 hours I noticed that it turned to 14% battery . I was not using internet or using the phone .
A numbered app with number 10159 with a black Android icon used 79% of battery .
Help me . How to remove it ?

Welcome to Android Central! Usually, those numbered listings refer to an app that has been uninstalled already. Did that battery drain persist after another full charge?

Thanks for another thread which has the same issue on Galaxy S7 and my proboem was solved by taking full charge cycle again . Yes it is completely removed . And thanks to you Sur for responding to my thread. It is so much thanks to you
