If I recall properly, Android has a timer class that is for applications that 
require some scheduled polling each 15 minutes, for example. That kind of 
timer groups the wakeup of some tasks at the same point, so it maximizes the 
time spent with idle CPU and idle wifi/data connection.

But I feel that this kind of feature is not doable without cooperation of the 
underlying system (otherwise how could two Qt applications cooperate without 
knowing about each other?), so I doubt is doable in a cross platform way. :-(
