Firstly, the M240 battery is much larger (1800mah vs 1100mah for the M10) and the live view is almost useless for me, so none of my problems with the M10 applied to that series of camera.
The metering seems more sensitive to off axis or backlighting than I expect, and the camera is programmed to allow more of the scene to blow out than any other camera that I use. I should add that the MM and typ 246 metering behaved essentially the same, so it's not my individual camera or the M10 alone.
This is 2 2/3 stops under compared to the meter reading

In the same circumstances, basically every other camera I use from Nikon, Fuji or Pentax needed minimal or no compensation. Neither did the M11 in higlight weighted metering mode.
In terms of battery life I get about 250-450 shots a charge. It is much more towards the worse end when the weather is over 35C, which it is for half the year here, or thereabouts. I do use the EVF or live view quite a bit, whenever I shoot fast lenses relatively wide open. The RF is not accurate enough to focus fast lenses close up, and it doesn’t help that when Leica services my lenses without the camera they standard they use is sufficiently off that I have consistent problems. A number of us in my local Leica group have noted this and
@Dante_Stella noticed it too. I don’t like the way the tonality changes away from the plane of focus. Even when I sent my lenses in with my camera only about 3 of 5 came back focusing really accurately with the rangefinder.
In
Rajasthan one day I photographed basically all day. 14h or so. Thus is not that unusual for me, historically. At the end of it I had about 30% left on my last battery. The first one was nearly recharged from a power bank, and would have been ok to go if I hadn’t downed tools for the day, but again, the M11 was fine on the second battery with the equivalent amount of shooting. At one point the M10M got too hot to touch and the screen stopped working until I cooled it down.
How you work might vary, but I keep pretty detailed notes and this has proven itself over about 40,000 frames with the M10M since March 2020.
