Screen size and battery capacity are not a tradeoff. The bigger the screen the bigger the case and the more room for a battery. From the long-lasting tablet batteries we've learned that battery capacity increases faster per increased quadratic[0] volume than the increased battery drain from the bigger screen area. [0] Battery volume increases only quadratically because the manufactures insist on maintaining thinness. It would be interesting to understand how thickness could affect battery capacity.
