Looks like Ricoh have found a way/ways of optimizing battery life even when using the lower capacity D-Li109.
The (at least my) question now is: why didn't they advertise that properly?
I still don't think this battery is good enough, specially after what I have read about cycle life in lower tempuratures, and marketing advertising in way - how good this battery is, would be almost false.
CIPA standard is pretty correct.
I do think Pentax can do MORE to increase this battery life, with several things .
In LIve View you have Cling Clang thing to review shoots in Play mode, or to enter the MENU. Solving that would increase battery life, at least 5-10 %
I would also consider in future firmware option for minimal time to trigger Stand By, which is now set to 1 minute
Here it can be one more option with 1/2 minute and just LCD off, not real standby, with mirror clang.
That could increase the speed from waking up to almost instantly and faster then it is now,
and also it could decrease battery discharge.
