Re: "Apple had no duty to disclose the facts regarding software capability and battery capacity."
You can't convert hp in to kW. These are not "bhp", i.e. brake horsepower, measured on a dynometer. They are "taxable horsepower" (https://en.wikipedia.org/wiki/Tax_horsepower), calculated from the bore (not the stroke!) and number of cylinders of the engine according to a standard formula. My modern 1200 Triumph motorcycle would have 13.5hp according to this formula, but is claimed to develop 135bhp.
