Live view and video eat battery, and have a high power draw which makes the camera run out of juice much earlier than would otherwise be the case
Yes, I'm aware of that. I've had LV and/or video on for no more than 5 mins in total over all three charges. Surely that isn't going to reduce the battery life to half or less?

(whenever the batteries are depleted during live view, I can normally turn the camera back on again and the battery indicator is back up to halfway, allowing me to take loads more shots - as long as I don't use liveview!)
Yes, I've noticed that too, towards the end of a charge.

However, third party batteries are so cheap I would recommend buying a clutch of them from 7dayshop and keep spares at all times.
Yes, I don't mind doing that. But I really want to get to the bottom of why I'm finding such a huge difference between actual and advertised performance.

If there's an underlying problem, I want to identify it as soon as possible. Equally (and more likely!), if there's something dumb I'm doing, I'll be happy to correct it.

it can be very difficult to judge as it depends so much on how much focusing we do, how much reviewing, how much messing in menus....
Yes, indeed. I did a lot of all of those for the first charge, and got just over 150 out of it. Then much less of the messing with the subsequent two charges - no more than I would do with the K10D.

Having said that in a week's holiday shooting maybe 200-300 images per day only one battery change was required. The second battery was still going strong at the end of the week. That doesn't seem too shabby.
Yes, that would be more what I'd expect.

Wouldn't you have been concerned if you'd had to change it every other day?

1 more question do you have it to do any lens correction on the photos you take?
Good thought - but no. Both off.

I cant give any image count or run time, as I have not kept a check
In case it helps, you don't need to keep a check - just use PhotoMe to check the shutter count for one of your recent images.

One other thing I've noticed is that when the battery is close to empty, the level indicator on the LCD indicates 1 bar for quite some time - 50+ exposures on the last charge.

This is different from K10D battery behaviour, where it would indicate full forever, and then when it displayed as almost empty, I had about two shots left.

I'm not complaining - much better to get a bit of warning.

Just trying to establish whether this is normal. Have others noticed this difference?

I would suggest that the first thing to do is reset everything to factory defaults, and start from there.

Alternatively, go through each of the menus and make sure nothing is turned on for longer than it needs. Metering time for instance.
Ok, let's see...

Instant review: 3s (default = 1s)
All beeps: Off
Guide display: 3s (=default)
Status screen: Off
LCD brightness: -3 (default 0)
Auto power off: 3 mins (default 1 min)
Meter operating time: 10s (=default)
SR: On (=default)

I've highlighted the ones that are more than default.

Edit:

With Gwyn's comment in mind I've reset the instant review to 1s (the default), and returned the auto power off to 1min. I'll see what the next charge is like. Fortunately I've only just replaced the battery since the last charge died, so it'll be a fair test.

Does it seem likely that those settings would make so much difference that the battery life is more than halved??

Ouch that is very low... I got something like 450 on the first charge but has been creeping upwards since. Nothing like the D7k... I got 1400 pics on the first charge....
I only got 150 on the first charge. From what everyone seems to be saying, this is *much* lower than what it should be.

What could I be doing that drains the battery? I've got the LCD set to -3, btw.

Yes haven't managed to get more than 800 pics with the battery either. Might be the SR that eats a lot of battery!
I certainly wouldn't complain if I'd got 800 shots off a charge.

To clarify, that's 950 shots total, in three charges.

Not much more than 300 per charge.

But why only noticeable in live view
Also you tend to move the camera about more in LV, while you're composing etc. So the sensor is probably moving more than when you're exposing a still.

I noticed this yesterday with video too. Rather annoyingly, the SR rattle is picked up very noticeably by the onboard mic.

Just resurrecting this thread rather than start a new one.

Two years later, almost, is anyone using one of these things? Would be interested to hear of any experiences.
