ok its been about a week of testing on my xv6800 and i got good news and bad news
the good
it does what it says about the processor speed and clock
the bad
it does not save any battery power by having the processor run at a lower speed
the test
i left 2 phones on my counter, same setup, same battery power, same programs installed except 1 of them didnt have nueclockcontrol installed. came back next day and phone with nueclock on it had lower battery down to 47% but, the phone without nueclock was down to only 66%. i did this test for a week now and same result.
the twist
i reversed the installation and now the phone that had nueclock didnt have it no more. same result the phone with nueclock had less battery power at the end of the test time (3hr minimum).
this is just my own little test and the results may be digfferent on your phone, i really like n2c stuff but, nueclock control didnt save any battery power by having a slower processor.
just my results
n2c still the best
