XTU Undervolting and display calibration

[KillerFry]

Hello there!

I bought my SP3 from Best Buy on Saturday. Truth be told, I pre-ordered from the Microsoft Store online, but even on Saturday it was still "In Process" so I just cancelled and bought at my local Best Buy.

Anyway, I'm wondering if anyone here has already tried to undervolt with XTU and maybe eke out better battery and less heat? I'm actually trying -0.15mV and running the 15 minute included stress test, see how that goes; but maybe someone has some preliminary tests?

Also, has anyone calibrated the display? I have no calibration whatchamathingies on hand. If there is an ICC profile floating around, maybe care to share?

... aaand, just because I don't want to open a new thread, but has anyone had a problem with the unlock screen not responding? It usually takes mine a few seconds - like 10 - before I can flick the screen to unlock the device. Anyone experienced this?

I don't think many people think about undervolting, so you are probably breaking new ground or just posting about it first.
Actually, maybe I should start undervolting my laptop, it might be nice.

Worth noting Windows has a built-in calibration tool.

I don't really have input to say about the unlock problem.
