"They have also removed the “high performance” power option from the Surface Pro 3. It used to be that you could essentially tell the Surface “fuck my battery I want you to kick ass” and that’s no longer an option. Apparently this has something to do with the new quick wakeup abilities."
You don't want to use High Performance. Many laptops and mobile devices have reduce performance compared to Balance, as the system gets too warm, even hot and that starts throttling system, or Turbo Boost is disabled. Meaning instead of having the CPU jump to 2.9 GHz when you need it when you do something intensive. It will lock at 2.0GHz, for example, or the max will be 2.5GHz, or something (varies between mobile devices, and CPU model, of course. The mentioned numbers are used as an example, and does not refer to any model of the Surface Pro line).
