Marshmallow Battery Life - Disappointing so far

Looking much worse than Lollipop
It is the WiFi and Phone radios that seem to be using much more than before

It usually takes about a week for the new ROM to settle down, and it uses a lot of data during that time, so depending on whether you're on wifi or mobile data at the moment, that's the one that's going to get hit. If you move between them (wifi at home and in the office, mobile data on the commute, shopping, etc.) they're both going to get hit for a while. It's been like that since at least Eclair.

I've got the same WiFi and phone radio consumption. Why does it take time for a ROM to settle? Interesting to know what it's doing.

I've got the same WiFi and phone radio consumption.

Did you do a factory reset? or just the update?

I have just done the update so far. May go for a factory reset when I have time at the weekend

I kind of did one by accident, was trying to wipe cache partition but it's changed on marshmallow. To be fair I am starting to see the battery life getting better after messing around with location services etc.

Battery life with Android 6 is awful.
Between 25%-30% of battery drained at night while inactve, with and without 'Battery saver' active and even with 'Plane mode' on.
No data traffic or active apps, mainly "Cell standby"(38%) and "Phone idle" (24%) tasks.
PD: I´ll try factory reset

Definitely seems better after my factory reset, particularly overnight in Extreme Power Saving mode with Priority Mode
