Man, the thread has about 500 post but to sum it up:
Lots of people complaining about battery drain
Endless advices for 100 - 0 recalibrating that does not help in many cases (I also tried)
Final admission that it is SW problem and
unofficial assurance that it will be fixed in next release
This all took several months. What is contradictory to what I said before?
