In Android, if you open an App, but only once, it may be kept in memory for a long time if the memory doesn't suffer any shortage.

Will these background tasks/processes consume power continuously? Will it be significantly?

Answer 1

If the app requires that it runs in the background, then yes, it will consume power as long as the phone is on. One app isn't exactly that significant, but the real problem comes up when multiple apps start running processes/services in the background. In fact, most battery-saving apps out there disable these to save power.
