Should you leave background refresh on or off?
I turn on but manually switch off for all apps except whatsapp.
I keep it on except for a few apps with a propensity to eat up battery life.
Everyone has it backwards. A battery glutton app needs the refresh to run more efficiently! The insignificant apps are the ones you can turn off in Background App Refresh.
Facebook is using a fraction of the battery life it was prior to turning off background app refresh.
Do you still get notifications if you swipe an app like FB or Tapatalk away from multitasking?

That's why I do it for apps I don't use much or ones like FB that are known hogs. I also do what you do and limit my location access to apps that really need it, like Untappd.
