I have been testing those settings and i noticed that with continued use my battery drains from full to about 15% in about 8-9 hrs, these a what i have running

-Nokia messaging config to push emails from 8am-8pm everyday with 5 email accounts

-ovi contacts always on 24hrs

-sociality updating every 30mins

-forecaweather updating every 8am

-data plan monitor widget updating every 10mins

-widgets include; data plan monitor, ip address, email, conversations and media player

-the occasional call, sms and IM every 2hrs approx, and web browsing and twitter every 2-3 hrs for 10-15mins at a time



Standby battery usage has been very good, overnight battery consumption about 15%, but i think its because i have sociality, ovi and all the other widgets constantly running in the back ground.

I think the ideal settings should offer a balance between continued usage and standby time
