3. What i expected :

Energy when full - 78.7 Wh (Anything less than the design value)
Energy(design) - 81.2 Wh

4. What i see (See attached screenshot):

Energy when full - 231.7 Wh (Grossly incorrect)
Energy(design) - 81.2 Wh
This also results in an incorrect value for Percentage - 31.3%
This also conflicts with Time to full field
