public boolean isFullyCharged() { 
   return MAX_BARS == 8; 
}

MAX_BARS is a constant so it will always be == 8, so this method will always return true. This method wants check what the current charge is, so instead of comparing the constant to the magic number 8 lets check if the current charge is == the max charge.

public boolean isFullyCharged() { 
   return mBarsCount == MAX_BARS; 
}
