Default [APP REQUEST] Battery sync

Hello to all you developers out there
I would like to request a very useful app. It is the concept that it refreshes the battery stats regularly so for those devices that display false battery it can be corrected
I know his because my phone when I shut it down it comes up with a different battery percentage every time I turn it on
So can some one develop an app like this which refreshes your battery stats without rebooting device.
Would be great help to everyone
