If WiFi is on all the time, then yeah, the battery will definitely die in about 2-3 hours. I think one hour is a little bit on the low side though, so maybe there is another issue going on there.

What are you using WiFi for? If you don't really need it, then I'd highly suggest to set the S70 to have the WiFi timeout quickly. Then you will have some pretty good battery life.

Also remember that the backlight of the touch screen is the other thing that can burn battery life. I always set Nevo controllers to have the backlight timeout after 15 minutes (unless they request for a longer timeout, which happens sometimes).
