My battery life is not as good as before the update. No concrete numbers to share and it hasn't really been a problem but sometimes I get incredible on screen time. 3 1/2 hours is usually no problem and sometimes over 4. I am usually down to 20% when that happens. My phone comes off the charger at 6AM and normally home by 5PM. Hate to put it on the charger right away so usually not until 9:30PM. I think it was a little better before the update because I never felt like it was getting low.
