How long will battery last, assuming no usage Short question:
How do I find how long my battery will last, taking into account the current settings (Airplane mode, Battery saver, etc) I have enabled, and assuming I do not use it?

Detailed question:

When I open the Battery usage app (?), I am given 3 numbers...


Usage on battery
Estimated time remaining
Last 3 h of usage


I understand what #3 means.

What does #1 mean?

The time given by #2 does not make sense. I currently have 2% remaining, with Airplane mode and Battery saver mode turned ON, and it tells me I have 14 minutes remaining. But it has said that for the past 30 minutes. (Note: I have only used my phone a couple times to quickly check on the battery in the past 30 minutes.)

I did some searches, and the closest questions I was able to find was here and here. But neither answers my question.

That usually refers to the impact on battery given by a single app.
If you expand you are supposed to get a list of your apps running, ordered from the most costing ones in terms of battery usage.
