Power consumption on Status Bar

[sim]

i have MyWi app on my iphone and its showing the battery drain.
is there any app to show battery usage (drain in mA) on status bar?

it would helpfull so much. i could see when power draining fast, so i can close or configure some apps.

googled it too manytimes but couldnt find anything
