Count down time in notifications dropdown

[Dumbarse]

Hi,

Have 4 days 7 hrs in top RH corner in notification icon area,
appears to be counting down.
Any idea what this represents?

Thanks

That's the countdown to WW3...
Kidding.
Did you set a reminder or timer?

I would assume it's the estimated time (based on usage) that your battery has left.

Battery percentage left, if there isn't anything running for application pull down - that is usually staying safe at the battery option, I do not look at it at all. More or less though, and do not want it to idle either.
