    I'm about to purchase a 2017 Macbook and I'm confused about how the various processor options impact battery life, heat etc.

    Is anyone with an i7 seeing great (~10hr) battery life?
    My assumption was that the M3 would offer the best battery I wrong?

    No clue. All I can say is that my i7 2017 Macbook easily lasts 10hours. Sometimes it lasts even longer, kinda depends on what I'm doing with it.

    I just ordered an 2017 Macbook i7.......I'm sure it has some impact, but I expect it to be minimal.

    Its not a true i7 like you'd get in the MacBook Pro, its still the Intel M7 series from the previous year but with a new name tag. They're now called "Y Series" processors.

    As it was launched by Intel today, and available by OEM partners next month, any chance we see a Coffee Lake refresh on the MBs by year end?

    I'd say it's just about nil.

    Specifically, the 8th gen Y series was NOT launched yesterday. Expect an announcement for the new 8th gen Y series 8Yxx chips around early Q1 2018, with new 8th gen machines to show up in Q2 2018 or so.

    My 2017 m3 is a battery slayer! I'm getting up to 12 hours. It sips power - my energy monitor shows it's often using around 4 watts of power but it can go as low as 2.5 watts in idle.
