If I close the mail app on iPhone 5S, can I still be notified of received e-mails?
I usually try to close all apps not in use from my phone to save more battery, but I always leave the mail app running in fear that if I close it, I won't be notified when I get new e-mails. Can I close it and still be notified or not? Also, same question for Snapchat. If I close out Snapchat, can I still be notified when people send me snaps?
