    That's interesting with the turbo boost, maybe it saves battery as well?

    With turbo on, can I ask what temps you getting with gaming and non gaming? I am assuming non gaming doesn't come anywhere close to 70s?
    The throttle behaviour may not be thermal throttled, do you know how it's throttling on recommended mode?

    I've been doing some more testing on this and yeah, apparently the 65c-ish limit on "RecMode" and 95c-ish limit on "PerfMode AC" is pretty much true.

    Why, because it IS thermal throttling - as can be seen that with Turbo Boost off, it hovers well around the limit temp (65-ish) - which also probably means it can take the slightest bit of Turbo (maybe 20) but I don't think it's gonna be worth the pain to tweak the Turbo Multiplier for an extra 0.2Ghz of clockspeed over the Turbo-less standard.

    Though arguably, as you have correctly pointed out, running with Turbo On for normal work loads might be doable without any clear signs of throttling... Turbo Off actually seems to net me a consistent 1h+ increase in battery life for only a slight decrease in perceived smoothness so yeahhh.

    Comparatively, on AC + PerfMode I'm getting sustained loads near 95c, with slight stutters unless I disable BDProchot (which probably makes the as-hot MX150 pre-signal the Proc making the proc throttle anyway in anticipation as it comes near the 95c limit - which it DOESN'T do when it's off = means we get to hit that limit).

    Didn't feel all that comfortable pushing the thing to so close to the bounds of its temp envelope with BDProchot off (especially with that poor single fan), so I went and fiddled around with the Turbo Clock multipliers. And yeah, lowering things a bit I definitely get a whole lot better balanced, less heaty Turbo while on AC-PerfMode.

    Which means a lot smoother unthrottled ramp ups without having to turn off BDProchot to get rid of throttling (or turning to Turbo off completely).

    Which pretty much means that, clearly, temps are the limiting factor here, and the Envy simply can't cope with the heat from a fully Turbo-ing WL-U i7 without the extra sinking available with PerfMode's harder working fans (which even if we could force, would be a huge load on the battery anyway).

    Which I'll pretty much chalk up to the price to pay for having so much power stuffed up something so compact - considering that without heat Mods, the MateBook X Pro isn't doing all that well either.

    I guess if better ungimped CPU/GPU performance is what you're looking for, then something like the slightly bulkier PS42 and it's twin fans (and better cooling) might be a wiser bet (despite the single channel RAM).

    That's what really held me back from the MSI PS42. Single channel ram. Not really a big deal in some cases, but there were enough cases to make it a sticking point. Lack of USB-C charging on that model, too.

    Same case here. Nearly went the PS42 way myself but the larger size, single-channel RAM and DAT JELLO chassis drove me away.

    So I decided to open a whole other can of HP branded worms lol.

    BTW, if anybody was wondering - manually tweaking Turbo levels to a slightly lower range (though TS) ALSO works to make the Envy 13t run games on battery without throttling - as long as I keep stuff running below 75c-ish...

    So at least I'm getting a liiiiiitle bit of Turbo even on batteries. Difference between Turbo-Off and Limited-Turbo (and Full-Turbo PerfMode) is pretty obvious when comparing New Dawn load times so yeah it does make a difference.

    And yeah even through the throttling and all the Envy is actually doing fine with even The Division 2 and Sekiro right now - which is pretty nice considering the sheet thermals and clocked down GPU.

    I wonder how the upcoming "2019" Envy 13 would fare in comparison with its MX250MQ and LPDDR4. Battery life claims look outrageous but eyyy, who knows.

    I'm unsure if the envy 13 will have a mx250 gpu which is kinda unfortunate. As far as I can tell only the envy 17 will have it which IMO is too big and I think mobility will suffer with it.
    Unless they plan to release it further on down the line, when though, is anybodys guess.

    I actually had access to HP's product site for the "2019" E13 April refresh that looks pretty legit because it even came with an updated product video/images/descriptions with the "proper" new microSD slot placement on the opposite side AND the new webcam disconnect switch (but the site is kinda hidden and is pretty hard to Google up).

    If the content from that site is to be believed, the 2019 E13 WILL supposedly ship with a MX250 variant, perhaps unsurprisingly as that's what the new MBPX and UX3xx models are gonna ship with too.

    Though I've got to wonder how much extra heat the 250 (MQ or otherwise) would generate at full clocks coz the current cooling config of the E13 can't even deal with the WL-U/MX150 without tuning the Turbo down and there seems to be little (if any) hardware changes to the "2019" model in terms of temp management.

    Also that site is my source of the "outrageous battery life" comment (claims the battery will last nearly twice as long as the "2018" WL-U E13). A bit of a bummer if true (more battery life is always good), but my current unit does do a respectable 5-6h on surfing loads so I'm not too salty.
