The 9810 has a faster CPU, more memory, a larger screen and HSPA, all of which will consume more power than the 97xx. I generally charge mine over night in the docking pod, and again when I get home from work. During heavy use days I occasionally need to top it up sometime during the day, in the car or office. I usually don't let the battery drop below 70% if I can help it since Li Ion batteries don't like to be repeatedly discharged anyway.
My other Blackberry is a PlayBook.
