In iOS 6, you can set email notifications to appear on the lock screen without any preview - only the sender's name shows. That's exactly what I need, because there are times when I don't want anyone who's looking over my shoulder (or finds my iPhone) to see the message subjects. But, unless the iPhone is completely turned off, the screen lights up for 15 seconds whenever an email notification appears. As best as I can tell, there's no way to prevent this for when, say, the phone is in my pocket or otherwise out of sight. I get about 50-100 emails a day, so that's potentially a lot of wasted battery power. For those times, I'd prefer to just get a vibration or audible alert. Anyone else notice this?
