Lenovo Thinkpad t431s battery life in linux?

Question

linux

Hello everyone,
I'm thinking of getting myself a Lenovo Thinkpad t431s, but I'm very worried about the issue of battery life in Linux. Practice with the Thinkpad X1 (not Carbon) showed that even with all the tunings, more than 3 hours of moderate work could not be squeezed out of it. I'm afraid that there would not be the same ambush with the t431s, but I can't google anything, apparently the model is too new.
Maybe someone has already purchased t431s for themselves, successfully installed linux on it and can share their experience?
Thank you.

I don't know about this particular model, but my Lenovo X230 with Intel® Core(TM) i5-3210M CPU and 4574 mAh battery almost delivers the promised 7-8 hours on Ubuntu 13.04 with 3.8 kernel. But in my opinion, something else was improved in the 3.10 kernel in terms of power saving of new Intel processors (http://www.xakep.ru/post/60865/ - Better support for Intel Haswell and new CPUs), so I think after the upgrade it will become even better .
