Red: You definitely either have a bad unit, or there's something wonky going on with your phone. I am NOT a paid shill and I've experienced none of those issues. Doesn't seem to effect my battery life at all. The Chromecast app has never showed me a tab with celebrity videos, nor is there even one at all for me. It's just "What's On" (which just asks what app to open), "Devices", and "Get Apps." It plays back great from multiple apps. Sure, there may be a few people out there having some issues such as yourself, but it would seem that your experience is in the minority. I'd exchange it for another unit and try it out on a different control device before declaring just how awful they are. Personally, my wife and I have been enjoying the heck out of ours.
Clas55clown: About the hi-res audio files, I use Plex to playback from my computer. However, I'd like to try out the BubbleUPnP app to see about playing FLAC files directly from my phone.
