Today, my phone has been telling me, "Based on your usage, your battery usually lasts about 4 days, 1 hr, 37 min when fully charged." I don't know where it gets this "usually" from since I've never let the phone drain below 65%, but whatever.
I think my phone's a little full of somethin'.
No doubt, but "usually" is a clumsy word choice. "May last" or "may last up to" would be simpler.It's calculating based on percentage
