Power Hungry M11

The camera needs most power for just being on. If I remember right it is about under 10 % per hour. Everybody can try this out by himself. Taking photos takes not much power, I would say it is nearly neglectable. Diplay and EVF are the next big power consuming parts.

I agree that taking photos doesn't take much power . . . but I wonder whether going to Standby and then waking up might do

Never a good thing when testing to change more than one variable, so I ran the second test with just the EVF enabled and I left the auto power-off setting at default.  Whilst beavering away on my laptop for the last ninety minutes I have also been clicking away on the shutter.   I let it randomly go into power-saving, other times clicked away keeping it active.  End result in the same time period and number of exposures as the earlier test resulted in the battery dropping from 80 to 45%, which would equate to circa 330 exposures of mixed usage (i.e. 50% rangefinder, 50% EVF).  In essence my camera/battery combination is likely to be achieving only 50% or so of the battery performance that others are experiencing.  Hmm.

That would indeed be interesting, but probably difficult for us to measure.

[M11 for me]

Thank you @elmarsand @jonoslack. I will try it out. I must say that the long duration of that waking up process might be annoying. And if we want to avoid it then we can set the setting accordingly. Its now nearly 11 pm here and I have set the energy modes accordingly. As I often leave my camera "ON" permanently (with other settings though) I can report tomorrow if the battery is fully down or not. At the moment battery is at 95%.

Hope that that makes sense. Will tell tomorrow.

[M11 for me]

Well I have my M11 here and the battery shows 45% after 12 hours down from 95% last night. 

That little "test" shows that with camera stand-by "off" the battery goes down even though the camera is untouched and no photograph is taken.

A compromise might be to set camera stand-by to 10 mins and monitor stand-by to 30 seconds. Like this during the shooting of a sceene you can avoid the situation of weaking up your camera which some claim that they lost shots as that weaking up process is too slow.

Thanks for your test result and suggestion - which coincidentally I have just tested with those settings (camera stand-by to 10 mins and monitor stand-by to 30 seconds).  Using the same ninety minute period and number of exposures (90) as per my earlier tests, again with LV/EVF active the battery dropped from 100% to 70% which pro-rata means just 300 exposures from a fully charged battery - not at all what I had expected.  

I am tempted to inform the dealer of such poor performance / high power consumption and if nothing improves in the next week or so to ask for a replacement battery, in the hope that this could rule out a camera problem.

I am happy with my Leica M11 + Visoflex 2 battery usage. I have set camera so auto review is off, hybrid shutter, my EVF turns on with the top function button, and the power saving timer for my camera is set to 2 min, display timer 30 sec, 5 min sleep time on FOTOS WiFi, which I have only used a little to test camera control. I have never gotten below 50% charge, even when shooting dozens of photos in a day, and I typically charge the battery only after several days. I do have a spare battery, as every owner probably should.

No, normal usage is an hour or so walking about and less than 100 exposures, sometimes just a few dozen, if that.

But it also means 4.1/2 hour of use with it permanently on (because you're taking a picture every minute and it won't go to standby - so you can set it to no standby) and you could easily take over 1000 images in that time. As @elmars pointed out above, taking a picture doesn't use a lot of battery life, but leaving the camera on does.

I'd be interested in your results if you took 500 pictures in your 90 minutes (and see how the battery looked then)

Your test is fine and meaningful, but it doesn't imply that the camera will only take 300 images on a charge. . . . . unless you shoot 1 image a minute.

Then it'll last about 4.1/2 hours  (do you often walk about for that long?)

Hard to find guidance from Leica because there are so many variables.

But I turn Standby OFF and monitor to 30 seconds - that way it starts instantly which is just right. I have a suspicion that starting and stopping might use quite a lot of energy, whilst leaving it on does less (the problem is when you put it in your bag overnight turned on). There was quite a move for Leica to introduce a 1 hour standby option, so hopefully that will happen.

You just must not forget to switch the camera off at the end when using such setting. !)

No problems here. Recently spent two weeks shooting every day, morning to night. No evf.  Power saving on where I have to bring the camera back to life after not shooting for a bit (which caused me to lose some shots because of the unusually long delay…). However, no charge needed until the end of the second day of shooting where the battery would drop to 20-35%. Pretty good by any previous camera standards for me.

Have you followed @PeterGA‘s advice in post #9?

It took a couple of weeks for my initial battery to settle down to the point that I get about the same performance that @jonoslack described above and in his excellent review of the M11.

I almost always turn power management off so that the camera is instantly ready take a shot. My battery drains a little more than 10% an hour, which equates to over 7 hours straight of walking around and shooting. I have set the camera to display the last shot taken only if I hold the shutter button down while taking the image.

Thanks.  I have taken on board all recommendations etc but continue to find (even after six recharge cycles) that battery level does drop more quickly than I would have expected and a full charge comes nowhere near Leica's stated figure of "approx 700 shots (in accordance with CIPA Standard in rangefinder mode)".  

Reference battery drain, with the camera on, battery reading 70%  and with power management off I noticed the other evening that after four hours of the camera sitting untouched, the level had dropped to 10%, so dropping somewhat quicker that your 10% per hour.

Anyway, opportunities for any meaningful photo sorties this week look to be very limited, which is a bit of a shame as the M11 is such a delight to use and is everything I had hoped for in changing from my M240 (which even after nine years of use remained a portly and heavy beast in comparison with my M7 and latterly my M10M) - aside from the niggle with the underperforming battery which I will endeavour to ignore.

It sounds like either the camera or battery has a fault then. There could be a short circuit that is draining power even when nothing is going on. Does the battery experience significant power loss when it's not left in the camera? Do you have a second battery to test the camera power loss? You may consider requesting an exchange based on a manufacturing defect. Don't delay.

Until today, I never tested it in the way described by Keith since my feeling is that the battery life using the M11 is way better than that of my SL2 (which is significantly better than my Fuji X-T3, btw). Thus, inspired by Keith's comments I just tested it. With power management off and live view / display off, the battery was going down from 90% to 75% in about 70 min. That would give something like 4 x 70 min = 4 h 40 min for the battery going from 70% to 10%! Thus, Keith's value of about 4 hours seems to be reasonable and in the normal range! It is definitely not indicating a defect.

I see it in a different way: When I am photographing a wedding for 8-10 hours (about 1500 images), I most probably only need two batteries which is fantastic compared to other mirrorless cameras and my former M10 (even assuming power management off and camera always on!). Taking pictures is not consuming that much energy, especially with the M11, as already mentioned above, e. g. by Jono.
