    The background illumination and the radio chips are the largest energy consumers. Mainly because they are on when you use the device.

    Grayscale would improve battery a little if and only if you would constantly pull down the notification center or do similar things that use composition of multiple transparent layers.

    If you turn on Airplane mode, your battery live will improve dramatically, because you don't switch cell towers or look for WiFi signals.

    Whenever I drive or don't use my phone I'll try to do that.

    I also try to be a little less available to people. They have to learn to call me back or not expect a response within 10 seconds.

    But that's related to age, I suppose.

    Is Greyscale an iOS 8 thing as i do not see it in iOS 7?

    Why logically? Grey is just a color as much as red, green and blue are. The lit pixels don't know if they're showing a grey pixel or RGB pixel.

    Tested it last night and yes it does help out, I was using my safari and reading a couple of manga chapters for an hour and I only dropped 2%.

    iPhones have an LCD display, not AMOLED display. Therefore greyscale won't make an ounce of difference to battery life. Google for more info.

    There is a very tiny, almost insignificant difference.
