Which do you prefer? I read an article on Lifehacker that said wifi had faster speeds, while Bluetooth connects faster and uses less battery. However, when I tried Bluetooth the other day, it seemed like I wouldn't get push notifications. It almost seemed like my iPad mini would only pull down data when I would load something, rather than have an active connection all the time like off of wifi. Also any experience on which is most convenient? I have an iPhone 5 so I do get LTE speeds, although Bluetooth seemed fairly speedy to me.
