Err - I'm using S2U2, 15 minute emails from 8am - 10pm and 30 minute emails from 10pm - 8am and I get atleast 36, usually 48-50 hours out of a charge. I usually send about 50 SMS/day, as well as reading books (Acrobat Reader - which I leave open) during the day, periodically - plus some other random usage. I'm not entirely sure it is S2U2. I don't have the 1% battery driver, though.
