45% battery drain in the night and Android activity?

[Steven P. Administrators]

My note9 has a new battery, but I've found it has drained too fast when off the charger.

 

I used my phone as an alarm because I had an early appointment this morning, and I saw that it had drained 45% of battery doing nothing during the night because it was at 100% just off the charger cradle when I took it upstairs to bed.

 

This morning I discovered that Chrome was responsible for over 35% doing what? I don't know. I have now set Chrome to be suspended when not in use

 

 

 

Even my Android TV appears to be doing something at night, those are the com.android.tv.settings and org.droidtv.playtv ones

 

Calculator shows 12 mins of use but I did not use it and when I open it and view History, there's nothing there.

 

All the other entries are from my note9, but from 12:42 AM I was not using my phone.

 

The 8:11 AM entry is me setting Chrome to suspend when not in use.

 

Would appreciate any insight into this weird behavior. My account has 2FA so I would see if other people are logging into it.
