This is the state of things:
- during development we test all the common expected usecases with the
stock fw
- we make sure that the claims we make on the advertisement material and
in the box are backed by corresponding reality
- the last number i saw were pointing to above 20 days of standby idle
(meaning that you charge the battery and let the device untouched for 20
days) even if we officially support about 10, iirc
- the higher frequency does _not_ affect negatively the use time unless
you are doing something cpu-intensive

I would suggest you to do like others have done before: try without any
extra application, then proceed by bisection, by installing half of
those you have now and see if there is any significant decay of battery
