So, I've been wondering what's the actual difference in battery life in the latest gen (A7SIII, A1, AIV, A7RV) vs last gen (A7RIII, A7III, A9, A9II, A7RIV). I did notice some increase in battery usage on A1 vs AIII, but I put it down to bigger EVF, more power-hungry processing pipeline, etc. Reports vary across users though.
It came to my mind recenly, that interval shooting allows for a simple test when the main limitation is how much power the camera consumes just by being "on". I used the maximum interval - 60 sec and LCD turned off to allow EVF sensor to shut it down also for most of the time (as I'm only checking the view 2-3x for the full duration).
on a fully charged (but 2y old) battery I got about 172 shots in 2h 52m before the battery died. It got pretty sunny in the end and the camera took some heat, so indoors it could probably be a bit better.
I think this is more or less in line with my typical "take the camera and go" usage, where it takes > 4h to deplete the battery (the camera is sleeping for some of that time and the shoots happen in bursts, rather than spread out evenly, but there's some chimping on LCD/EVF as well).
Did anyone try such a test to see how long the camera can keep on running and taking pictures?
I'd be very interested to compare the results to A7III or A9 or A7RIV for example, as my impression is that those bodies managed to keep the camera running a bit longer on the same battery.

Thanks for your input!
