in numerous places, it is mentioned that app widgets should not get updated often, to minimize power consumption.
But, let's consider that an application is doing something important (such as audio recording) for a short period of time, say 30min.
In this case, is it acceptable to update the widget every second from a service?
How can it be that this would consume so much power?
Please consider that this is different from a widget which would update very often during the whole day.
And in my case, such frequent updates would be meant to allow the user to monitor that the operation is being performed continuously and correctly. It's not for fancy visual effects and such.
