Originally posted by CWRailman I keep very careful and accurate records of my camera battery usage. This month I have tested the Q, Q10 and am now using the Q7. On all of these camera’s the best I can get from one battery charge is 90 shots with most of the charges giving me 75-80 shots. This has been about the same for all three of the camera’s that I tested.
A fully charged battery is reading 4.18 volts. The camera usually shuts off when the battery gets to between 3.16 and 3.21 volts with one such reading of 3.44 at shut down. I have the image review screen set to 3 seconds, I am using the camera as I believe most folks would with about two minutes between shots. I have not increased the screen brightness over the factory setting. All this testing has been with .jpg. No HDR or other long processing. None of my shots are with flash and I remove the card from the camera for image transfer to the puter. What settings are needed to extend battery life to the advertised 250 shots?
I get the same results whether I use the Pentax battery that came with the camera or the slightly higher 1100mAh Wasabi batteries. I have read through many of the postings that deal with battery life and did not see an answer to this question. If it has already been answered could someone direct me to that info.

I don't think you will ever get 250 shots put of a battery, and the life was one of the things forts commented on for the Q when it came out. Part of the trade off between using an existing or new battery, and of course, the small size.
Power pack or AC adaptor is about the only possible benefit to get more life, and of course reducing the on time period between shut downs.
I don't count but I know the Q gobbles batteries much faster than my DSLRs. I use mine mostly with the standard zoom, wide angle zoom, and the PK/Q adaptor.
I pack 7 batteries when I travel, and 2 chargers.
