Get the remaining battery time available from an Android phone

Question

Is it possible to get the remaining battery time available from an Android phone?

Thanks.

Answer 1

There are a few apps (battery widgets and the like) that estimate time remaining before the battery runs out. I'd guess they take current battery level and try to work out current drain based on processor usage, backlight level etc. In my experience they aren't too accurate but in principle if you get the algorithm right it should be possible.
