This photo shows that you need at least 9 volts to wake up the battery controller after it being set to shipping mode, it has absolutely no indication of any power usage requirements for the device to operate. Even if the power usage of the device falls into this range, it is a coincidence and had nothing to do with this image.
I highly doubt it’s going to need a supply that can do at least 9V to exit shipping mode, at least I haven’t yet seen a device behave like that. I more so think that’s what power supplies Valve suggests to use if you want to play and charge simultaneously, that being said I believe actual power usage is going to be somewhere around those 27W at max so the battery doesn’t discharge, with 45W being a buffer to charge the battery while in use, though that’s still just a wild guess.
Sounds to me like 27W is at most its peak power draw, and I bet there’s even still buffer in that.
Yes, looks like it’ll usually be pulling 20 watts or less. Still a lot though
This guy has one already through the developer program and make a few videos about it https://youtube.com/watch?v=MbFGt-KUv9M
Actually you are probably right, my other post of the climbey dev did show a way smaller power draw 🤔
I hope the frame supports bypass charging. Like i’m certain i fried those batteries fairly bad already in my Pico 4 in less than two years because i use it so much plugged in. Two hours for one charge is just too damn short.
Pretty much every modern piece of USB-PD equipment supports bypass charging… What killed your Pico’s battery is most likely the heat not the possibility of there being no “bypass charging”.
Ney,
bypass charging isnt even nearly as widespread as you make it out to be. There are news articles written when a big phone manufacturer finally updates a device to support it. IMHO usb-pd is the same mess like with everything when it comes to usb standardization.
Pico 4 batteries are in the back like with the frame. Sure charging also causes heat. But i doubt my pico batteries degraded because of their charging management beeing so bad that it causes heat death. thats just ridiculous.
“finally update a device to support it” are… are you seriously that dumb to think that a SOFTWARE update somehow “enables” a physical function?
Look into how PMICs and BMSes work internally and how the power flow looks when running from battery vs when running from external power. Quite literally in the latter case, power cannot flow from the battery to the power rails because it’s being charged, and when the battery is fully charged, power is cut off. That IS the definition of “bypass charging”.

dickhead
Holy shit are you mentally challenged. This is the very same PMIC feature I was talking about, and it wasn’t “enabled” period, but enabled WHEN USED IN CONJUNCTION WITH THE 80% CHARGE LIMITER. Very important distinction. Doesn’t mean the Pixel phones weren’t doing bypass charging prior to this.
But of course to realise that you’d need some comprehensive reading abilities which you clearly lack.
If a feature is present, but not being used, that is effectively the same as it not being present in the first place.
Uuuuuh, buddy…
Getting so worked up over semantics of bypass charging isnt a good look fou you.
Especially if you automatically treat people like they’re soo much dumber than yourself.
Nothing wrong with sharing some knowledge and while doing that correcting people if they’re wrong.
But i even looked up power management integrated circuits and battery managment systems. Idk but those arent even usb-pd or bypass charging specific things. Idk whats your point with that? Like that they exist and a 2026 high tech device will have them so the battery doesnt explode? Like, no shit?
Happy to see some sources that bypass charging is basically a requirement with USB-PD.
PS Fuck You
Personally I would be completely ok with 45w, if the headset can handle higher power draw without overheating I think it would be nice to both push the system and charge it.
Hm yeah that would be nice.
I’m just not sure if the headset can draw that much, as others have said, it might just be the maximum speed it can charge at.
Tbh both would be fine imo as long as it doesn’t overheat or cause significant hardware issues
It does look like the battery is at the back of the unit.
Good for weight distribution. Hanging the full weight on the front of your face is really uncomfortable.
The image doesn’t say it “needs” that much power, only that there is an optional mode, likely for high performance or so, but it will probably have heat issues then.
I think you’re reading into it a little too hard. I don’t suspect an optional mode based on what’s written there. Those power specs come from the USB Power Delivery 2.0/3.x standards. There’s 9 Volt USB PD that can supply 27 Watts at the 3 Amp ceiling, and the next step up is 15 Volt USB PD that can supply 45 Watts at 3 Amps. Since a 45 Watt charger is the one that’s recommended, I don’t expect heat issues there.

I am referring to the headline of this post that claims that “Steam Frame needs 27-45W of power to run”, which is not at all substantiated by the image shared.
You are right about the title, I can’t believe I just read over that first part of that paragraph. Even my other post of the climbey dev talking about his devkit shows a much lower power draw.
If the “special mode” is what I think it is, it’s just a battery saving method that’s also used on the Steam Deck. With that, it requires being plugged in to turn on at all, otherwise it just remains in stasis. After it turns on, it operates normally.
The recommended adapter specs are most likely just for optimal charging, nothing to do with the stasis mode.
That sounds interesting. How does it work on the Steam Deck?
It’s not a mode that would be used often as it’s purpose is to protect the battery if the Steam Deck is going to be inactive for a long time. Most people will only encounter it when they turn on their Deck the first time, as Valve ships them in that mode. You have to go into the BIOS to activate it, and when you want to use the Deck again, it will only turn on by plugging a charging cable into it.

Sounds like what another comment is calling shipping mode

Obviously I can’t figure out how to link to a comment
Yup. That’s another name for it.
You can’t cross-post image posts huh
