[War of the Worlds] What was an average day in the life of a Martian like?

There isn't much. But from the original source only, it is believed that they once resembled and functioned like Humans do.
But they are much evolved, they are octopus like with much large cranium, they do not digest foods directly instead are transfused with all they need, and on earth this is witnessed by blood transfusion from humans and also from a slave/animal race brought from Mars.

They do not have any visual or audible communication whilst on Earth but are seen to work together, so it is assumed there is telepathy there.

It is also known that they do not reproduce sexually, and are completely ignorant of disease. 

From the limited information we have about them and the hostile conditions on Mars (evident from their desperation to leave, so we again assume they find it as inhospitable as we would) we can guess the following:
They are a survivor race and have survived the devastation of their planet through genetic mutation or guided evolution.
Because of the hostility of their world their population must be small, and we have never observed any visual signs of activity on Martian land, so they must remain either underground or in cave complexes, meaning their society is closely grouped together and small in number. 

I imagine these intellectual giants as controlling their population size, expending as little resources as possible, and either largely in hibernation or set only on finding a new world and research into how to colonise it.
