Beautiful. If I call an Android application "HIV", knowing that HIV stands for "Human immunodeficiency virus" would not help me much, would it? So, it is not about acronyms. Meanwhile, operating system that runs on the phone reports itself as "Android System", as is explicitly stated in my original message. Not "Android OS", but "Android System".
I got a rather meaningful suggestion on another forum that "Android OS" is actually the low-level kernel, while "Android System" is actually the higher-level OS service layer, although it doesn't help much in answering the question of why "Android OS" starts eating up the battery sometime (acronym finders don't help much either).
