Any app to measure current flow on epic touch?

[taylormah]

In past devices, I could use Current Widget to find the mAh drain or charge rate, and therefore find when the device is losing its power at faster rate. I also need it this time to find at what mAh charge value does the screen become unresponsive while connected to charger. But Current Widget reports "no data" on Epic Touch. It makes me believe Epic Touch does not allow access to this value. But just to be sure, I want to double check it against other apps/widgets. Do you know of any such app, which measures current flow in mAh to/from the device?
