Android Core Apps Causing Massive Battery Drain

[BeetrootJulip]

I usually watch Netflix in bed then go to sleep. In the last week, I occasionally wake up to find my batter drained (down 80+%) overnight. According to GSAM, the culprit is Android Core Apps. Not sure what that is. I thought maybe Netflix was still downloading, but that's not Android Core Apps.

This is Nexus 6 on 5.1.1 using mobile radio only (no wifi).

Thanks.

I am having the same problem. I used to get home from work (9-5) with at least 50% or more battery. Now i get home with about 20%. Android Core Apps is using about 15% of my battery.
