The new profile code in gnome-power-manager allows us to calculate the amount of time the battery has until charged, and also the amount of discharge time you would have if you disconnected the ac adapter now.
Is this useful to expose to the user? If so how? What about a tooltip “Laptop battery 48 minutes remaining until charged (64%), currently provides 1 hour 45 minutes discharge time“. I really suck at UI wording, so better ideas please.
