Are you reading the article here? Or at anandtech? Battery is fine or chromebooks wouldn't be getting 11-13hrs on larger screen than the competition and blowing them away in gpu. You maybe could have said that about older chips, but K1 has no trouble sipping when desired. Again, check the chromebooks acer just announced for order (pre-order). You can clearly see everywhere, that Qcom is not behind, and was caught with their pants down here.

"After all, Tegra K1 delivers immense amounts of performance when necessary, but manages to sustain low temperatures and long battery life when it it isn't."
I'm sure the goal is tablet first, but the jury is out on phones (higher end is the only place they want to compete anyway).
