Just now, I was using a banking app. Unfortunately, when I was about to press submit I entered a no service area, so I locked the phone, left the area and then unlocked the phone 5 minutes later, only to discover that iOS had decided to aggressively unload the actively running app making me start all over again from the login screen 
I get that iOS has limited multitasking capabilities in the name of battery life, but ditching an active app is ridiculous. Is there any way to prevent iOS from doing that?
