Hi, I'm new around here, so please be gentle. Cant see this covered before. So. From the lock screen on my iPhone 4. Swipe up on the camera to get the instant access and take a photo. Put the iPhone back in my pocket - after an hour or so the battery has completely drained. Although my iPhone has the autolock setting as 1 minute it seems that when you access camera from the lock screen, the autolock timer is not enabled. I have to remember to hit the power or the home button to stop the camera eating my battery. Any suggestions, or is this a "feature"??
