Is the apple TV 3 ALWAYS supposed to be powered on even when its sleep? The reason i ask is, i run my apple TV Via my Note 3, because the LTE speeds are faster than my home network. I've noticed every time i walk into my apartment, the Apple TV is one of the first devices to connect to my phone. My question is, if i put it to sleep, why is it still connected to my wifi even when its sleep? Should i just unplug it every time i leave? Because no matter how i turn it off, if its still plugged in, it stays connected to my wifi. I got it for christmas, and my electricity bill shot up over 100 bucks from last month, i'm trying to narrow down what the cause was, one of the things i was thinking is because the apple TV was on 24 hours a day and connected to my Wifi. anyone have any knowledge about this?
