| | Re: 9810 Battery Life.
One of the bigest battery drains I have noticed is the HSPA radio establishing connection with towers that are a long distance away. If you turn HSPA off, or if you are in an area with good HSPA coverage you will get better battery life, maybe several days. The 9810 is a more powerful device so it does use more power than the simpler 97xx devices.
My other Blackberry is a PlayBook.
