I leave all three on all the time. The extra battery consumption is minimum depending on what is going on with the phone.
BT definitely does consume a LOT. It's always on and it's always seeking for devices it can connect to. I leave wifi on almost all the time and do pretty okay with it.
That's because you are using the wifi connection for data communication. If you do the same thing on cell data, you will find your battery drains the same or even faster depending on the connection and signal type.
You're saying cellular connections drain batteries faster than WiFi? That makes no sense. WiFi is for data only, which means you're still using cellular for voice and texts. I'm not an engineer but I know that 2 radios consume more resources than 1.
4G wireless data is a huge power drain compared to 2G or wifi. Can't speak experientially to BT.

I think it depends a lot on how built out the 4G/LTE network is. My provider in Canada (Bell) has been building out LTE like crazy. I don't really see any difference between it and 3G. I get around 2 days with my Ativ S between charges. I am not a power user though.

Same here. I got tired of constantly toggling wifi, Bluetooth, and cellular data on/off all the time and worrying over my battery life. I just leave all 3 on now and I don't notice much of a difference.
Good thing you are not an engineer
Read what OP said. He watch online video on Vine. If you watch video on 4G or 3G connection instead of wifi, you may use more battery juice. Try it and you shall see. Your voice cellular radio is always there. The only difference here is which radio you use for large amount of data transfer.
And in case you haven't bother to read earlier posts, on idle, they don't make much of difference whether you have wifi on or not.
