i've noticed that my nokia will loose it's charge over the weekend.

this friday night i used it. i did notice that as soon as i pulled off the protective grey case it turned itself on immediately. i thought that was strange. i did a little browsing. the battery meter showed full. i then hit the power button briefly and selected device off from the menu. i put the cover back on and put the device on a shelf. this morning i try to turn it on, and it comes up to the first Nokia splash screen for about 2 seconds then powers off.

This is the second weekend in a row where it's lost it's charge without me using it.

I don't use R&D mode.

Is this normal? Does the device suck power when turned off?

I had a same problem. Reflash fixed it, but now alarm clock doesn't work. :) Maybe I need to reflash it again..
