the update interval is now as often as uevents are comming from linux kernel. 
You can enable logging->power management and check in log how often it is - i 
think it could be those 20s.

AFAIK the battery charge is updated even when phone is suspended - the chip in 
battery does this.

Maybe we could force QtMoko to read it immediately after leaving suspend. The 
values should be fresh. I can check if it's easily doable.
