Possibilities when not using background app refresh I like the idea of Background app refresh in iPhone that whenever I open back the app, I'll get new content on screen. However, can someone enlightenment me what happens if i opt not turning on background app refresh? Will the app still update its content after I reopen it, taking the possibility that now with background refresh off the app after reopening shall now take few moments to refresh its contents. Does the background refresh option affect any apps basic functionality?
With background refresh an app more or less lets iOS take care of data refresh. If this is turned off it‘s up to the application on how data gets refreshed (on activation, on user demand etc). There is no general mechanism at work then.
