Well, I also feel like I need to report something (not so impressive but..) For a long time I've been using KP46, then KP47 w/o VDD enabled. My average long-term power consumption was around 16mA, which gave me about 3 days per full charge. Exactly a week ago I've installed KP50, enabled the default dsp profile (but avoided some frequencies) and, although the change is not so impressive, my average is now around 14mA, which is like half-a-day more (~ 10-15% longer time-between-charging). Other than that. everything works fine (+ obviously no reboots to report).
