K-3 battery life feedback

Have enough people gone through a cycle or two now, to provide a better estimate than some I've read? DPR shows 980 for K-5, under 600 for the K-3. Yes it's pushing more pixels faster and has a larger screen, but I'd be surprised to see this discrepancy turning out to be so great. Thanks all you new K-3 owners!

It's definitely more than 600. I just shot about 1000 frames doing continuous burst tests and the battery was still showing 2/3 bars. I believe the 980 figure, if it's per CIPA standards, requires 50% flash use.

I can shoot 6000 DNGs on my K-5IIs with 2 or 3 batteries, so I don't take such numbers very seriously! (I think they must include a lot of flash, which I don't find very useful for airshows!)

But the K-3 does appear to get through batteries faster. Presumably partly because of the larger sensor, but I suspect being a more "zippy" camera (it just appears to be faster to operate) takes more battery power.

I did more than 1280 pics on 2 different battery charge already. I did not shoot video and have pretty much all saving power options to maximize shooting.
I got a grip so I dont think It can be a real issue for me, it's pretty rare when I shoot more than 2000 pics / day.

My K5 was more on the 1650 number with the same settings.

It is certainly my experience that batteries do not last anything like as long as they do on my K5II.

Shooting a combination of RAW and JPEG I got over 1000 on my old K-5 battery. I used it while my new batter was charging.

I don't use liveView.
I didn't use the AA filter
I have auto-playback turned off
I don't do much chimping

I had AF-C on most of the time.
Center point AF most of the time.

So it's still a very good number but less than the K-5 models, just as one would expect for the performance boost and increase in pixels. Thanks!

Hey so I just wanted to chime in here I recently put my pentax K3 to a good test I went to a rodeo shot in continuous shooting mode the entire time with highest quality jpeg settings, I shot on a single battery without using flash 2000 photos of the rodeo and the fireworks afterwards then I snapped off 172 photos of the band after the rodeo I had finally depleted my battery after 2172 shots that's pretty impressive my previous Sony Hx400v and my girl Canon rebel t3i can't touch that kinda battery life. Oh also btw this is with a single battery in the camera no additional battery pack or anything of that sort and as I mentioned no flash the whole time either just worked the ISO range while it got darker. Oh another thing I feel is worthy of noting is I did in fact use live view about 85% of the time I really like being able to fine tune your focus in live view anyways I hope this helps I was able to push out 2,172 photos on a single battery charge with my pentax K3

battery life & GPS

I haven't been able to tell if the battery is failing on my k3 ii or something else is killing my battery life. Twice now I went through 2/3 of my battery in ~ 1-2 hours of use taking only about ~50 shots. I strongly suspect that its the GPS unit thats consuming the power. I'm not using it for continuous route logging, just "on". Since this occurred even faster when I was mostly indoors I think what is happening that the GPS looses signal in buildings and the algorithm used for "finding" the signal consumes a lot of processing power and has a high priority. So rather than timing out or reducing its questing time, it just keeps cranking away. Has any else had this problem?
thanks

I regularly shoot 4000 to 5000 shots a day on boat racing weekends without killing the battery in the body. Those are mostly continuous RAW shots. I've been extremely pleased with the battery life on my K-3.

I don't really keep count of how many photos per battery between k-5IIs and k-3; it is probably under 1000 shots. I generally keep 4 extra battery ready any time (each one marked with a date it was charged). On a given day, I usually have 2 batteries ready as spares.
