So there is definitely something I don't understand about the "Battery Modes". I thought, based on the "Nighttime saver" description, that my phone wouldn't sync between 10:00 PM and 5:00 AM (assuming I'm not using it). Doesn't this mean that I shouldn't receive emails/alerts during this time on the phone? My phone keeps syncing and alerting me of emails during this time, and it kept waking me up until I started putting the phone in Silent mode before going to bed. What am I misunderstanding about this?
