Silent push notifications only delivered if device is charging and/or app is foreground

Question

I have implemented silent push notifications but I have noticed some strange behaviour. The silent push notifications are handled via:

- (void)application:(

I also noticed the same and wasted some time figuring out. See https://stackoverflow.com/a/31237889/1724763

If you turned off Bg App Refresh, silent remote push will be dropped silently (the irony).

However, my observation is that if you connect to Xcode via cable, somehow the Bg App Refresh setting is ignored and all silent push for your app works.

I highly suspect this is an undocumented feature: charging causes the Bg App Refresh setting to be ignored.
