My quest 3 isn't charging with my link cable but the quest 2 did.. anyone know why?

There are already a few problems that I can List with my quest 3, such as the pass-through, though it is grainier than what is in their marketing campaign trailers. Though I love many aspects of the Quest 3, my main problem is the battery life. Though I don't blame Meta for the battery being smaller or that the Quest is more power-hungry, it is ridiculous that I can only play on it for about 2hr while plugging it into my PC while using it. I'll go from 100% to 50% in over half the time Quest 2 did, meaning I get much less playtime. With my Quest 2, I could typically get 4-6 hours of gameplay out of it due to it charging from being linked to my PC, but this headset will not charge quickly enough for this to be viable, which is almost absurd.
The charging on this thing is so bad that even with a higher-watt power block I use will take over 4 hours to charge from 20% to 100%. That is at least double the time it would take my Quest on similar workloads, but at least my Quest 2 wouldn't get that low as it would charge at a higher speed than it could utilize.
I understand this is a new product, but this has to be a software issue. So please fix this, as it puts a damper and a hindrance on your claims for this to be an excellent headset for both standalone and PCVR.

I know there's so many people with issues out there regarding this with the quest 2, but I cant seem to find a legitimate solution. My quest 3 drops from 100% charge to 70% after an hour of playtime. I usually play with 90hz, unless I'm playing a FPS. 

I am using a quest 3 with the official Meta/Oculus link cable, rated USB 3.2 Gen 1. My Motherboard is an Asus TUF x670e-plus, and I'm connecting my cable to the USB 3.2 Gen 2x2 port. I have disabled USB selective suspend in my power management settings, and removed all power saving features for USB within device manager. 

The only thing I have not tried is using an off brand link cable with external power delivery. Any tips or guidance is greatly appreciated.

To be honest they should check those temp range values then as the quest 2 gets 5x as hot as the q3 here in same exact situation yet it still charges up and works fine while q3 slows down charging.

On the PowerDelivery part, are you saying if the port was a PD port it would charge up fine?

Suggest a update to the link cable page as it comes across you could play forever using it with proper USB port which isn't at all the case.

I'm not sure I've seen a USB port capable of +18W that supports power and data at same time that isn't PD based. 

This also doesn't really explain why it's only an issue over link cable and not airlink. Same exact scenario and using airlink with a battery pack it will take the charge up every time no issue but link cable with same exact spec USB charge ability and it will not.

"Once the device is no longer in use and its temperature has returned to normal, your device should resume charging to 100% while plugged in to charge"

It seems this feature is bugged and it works only sometimes ...

Other times you need to unplug it and plug it again.

Its not a solution. Quest 3 has a serious hardware or software related issue.... Its killing batteries fast...PLaying a video stream (not gaming just a looking a netflix video) and headset fully  drained to zeroe within 1 hour 50 mins??? 5000MAH fully addon battery zeroed win 26 mins? Elite straps with batteries died?

May I know how to make the most efficient way to charge up the headset?

What protocol is preferred? QC or PD?

And how about the max accepted DC input? 18w or could be higher when the headset is at the optimized temp?

Right now, if I don't switch off the headset, it costs me more than 2 hours for a full charge because the headset remains ON all the time and I can check the battery via App anytime.

The temperature answer just can't be everything, it does not really make any sense. Maybe that's part of the problem, but there are other things goings on for certain.

I am very new to MQ, had it for less than a week. First thing that concerned me was if I can play games tethered and not live by the battery and I have had the worst time with it.
I will start off that I do use third party cables and charger (fast chargers for Samsung phones to be more exact, several) and they have the most problems. However it's not about slow charging, it's about not charging at all. If I use the charger that came in the box with the silly short cable, usually it works just fine, as expected. Every third part cable/charger combination has failed me so far.

I have had times when I had the headset plugged in a wall for charging, the orange light was on but it just was not charging, after 6 hours the battery was still at 2% where I left it. So then I figured out that just removing the cable completely, then first putting the cable into the headset and then putting the charger in the wall actually forces it to start charging normally, with the same speed the box charger does.
However it does not solve it. 3 times in a row now the headset charges to 34% then just stops charging (orange light still on). So what I do is repeat the re-plug procedure and magically it then charges back to 100%

Being tethered to PC or to the wall while playing - either there is no difference in how long the battery lasts or it's so small I do not even notice it. So that's pointless with the cables I do have.

I really would not mind spending money for the extra battery or the expensive link cable if I had any confidence that it worked, but it makes 0 sense to have extra battery plugged in if even tethered to the wall MQ3 can't take extra charge while it's running. That said it's clearly not power issue, it's software limited.
I don't throw out money for hardware that will come become e-waste in a couple years, I like to test it out so I am glad I didn't just buy the cable and strap from get-go. I love the experience using MQ3 but my only problem right now is this and it's enough for me to regret buying it at times till this issue is fixed.

Anyway, if someone does want to take a second look at this thread in future, here are my data:
1. Headset full version number: 57.0.0.297.669.526537896
2. PC App full version: 59.0.0.138.366
3. Not on PTC
4. Unplug charger and cable from MQ3, plug in cable then charger back. (It was still plugged in because I finished gaming with battery low and then just turned off the headset. Orange light was on but charge did not go past where I left it)
5. 3rd party for the most part.


EDIT:
I would like to update my previous post a bit.
For some time now I haven't come across the problem that MQ3 stops charging altogether, now if I leave it charging it always goes to 100% eventually. Thanks to that also when playing games while tethered to a wall I can play for more than 6 hours (haven't really tested full time possible that way) so it is now at least managable - I am no longer limited to 2 hours and main annoyance has dissapeared.
I don't know how, I certainly did not change anything on my end so it was either some bug that somehow went away or an update pushed to the headset.

It is however still not ideal that I can't charge the headset up while playing so this thread remains relevant.

Really would appreciate this not being marked a solution and continue to dig in on this as it doesn't make any sense. Nor did the remark on PD port make much sense. 

This also doesn't really explain why it's only an issue over official meta link cable and not airlink. Same exact scenario and using airlink with a nirvana battery pack it will take the charge up every time no issue but link cable with same exact power output spec USB charge ability and it will not.

I've been looking into this since I get my Q3 and it sounds like a poor software or PD  strategy for controling the charging and/or poor thermal management of the battery.

When the battery goes past a certain temp the software will stop the charging until the battery cools down again, as it does with most lithium batteries and as the Q3 is working harder than the Q2 I'm assuming it gets hotter under load? (I've not used a Q2 so don't know)
I'm using a link lead with USB injection, the PD charger is powering the link lead using a PD lead with a wattage display, I can watch the charge rate drop off as the headset warms up.

C'mon Meta this needs addressing, we shouldn't be taking the headset off and having to charge it mid game.
