Ok so this just started the other day, my quest 2 will no longer charge via the Oculus link cable, and when I play PCVR the Q2 battery is discharging fast, I'm talking lost 40% charge in 10 mins.
After playing around I have found a strange issue, the link is plugged into the USB C on my MoBo and when checking power outputs for USB ports the Quest 2 port is showing 0 power output, yet the link cable works fine just stopped supplying power all of a sudden.
unsure if this is a software issue in my PC, It charges fine via a wall socket
So far, I unplugged everything from other USB ports, no luck
Plug my Pixel phone into the link cable and it gets a power reading of 896 mA
Tested in a USB 3 port and the Q2 shows 500mA
Tested on another USB c-c in same USB C port and same issue 0 power output
Mobo is only 3 months old ROG Strix B550-F Gaming
if anyone knows a possible solution?
Updated with another test:
Using power cord that came with Q2, plugged into USB C port on back of PC, Phone plugged in reads 500mA, plug Q2 in and reads 0mA

I've tried using various adapters and max power output i get is 896ma. I'm going to look for an "ACTIVE" cable to see if the added circuitry triggers the correct power draw. The USB standard on power delivery is a hot mess and a bunch seems to be dependent on the device's firmware correctly asking for increased flow. With 896ma I can get 4-6 hours of play time as I lose 10-15% per hour. If the device would ask for 1250ma I think it would solve like 99% of the use scenarios

Just found a cable on amazon that connect to the wall charger and the PC then combines the inputs so it can get the correct power to the headset. I'm seriously debating picking it up.

Tell us about this... Link? Sounds like the best of both worlds.

here is the info. It has both a usb c power side for the wall plug and a usb a data side for usb 3.0. it also has a signal booster

I bought the split cable and tried it out this morning. I played for just shy of an hour and lost 8% at 72hz refresh rate, screen at max brightness. This is much better than the 12-15% loss at 90hz I had been getting. still not fully charging but I'll take the ability to play for 10 hours or so vs 4 or 5. of course YMMV. caveat emptor and all that

Same problem here - official cable with ROG Strix X570F. Used to charge fine before updates.

It's possible I'm a bit late to the game here, but I may have found a solution. It's not particularly cheap, but it works. At least it does for me. I just finished playing about 2-3 hours of Half-Life Alyx and my Quest 2 headset was still at 100%. (Note: Important to read my update in the next post below)
Here is what I'm using (see links at bottom for specific products):
The way I'm connected is as follows:
And that's it. That is how I play now and, as I said, the headset remains at 100%.
NOTES:
Good luck!

Update #1
It now seems impossible for me to predict a solution to this Oculus link charging issue. Today, with everything still configured as I outlined above, after 2-1/2 hours of playing Half Life - Alyx, the Quest 2 headset was at 50%, not 100%. Not sure why that is. I will monitor the post-play charge levels over the next few days and see if there is any consistency. At the moment, I cannot confirm that this configuration is indeed a solution. If anyone considers configuring their set up similarly, be sure the products are returnable if it doesn't solve the issue for you. Apologies for the bump in the road. Not something I would have anticipated.

[from a post I put in the wrong place]
I have suffered this same issue for months thinking it was a possible Oculus update situation and waited for a fix.
I was using an add in pcie card (BEYIMEI PCI-Express 4X to USB 3.1 Gen 2) with 2 ports known to provide enough power. It worked fine for months, but then out of the blue it simply stopped charging. I tried replacements and still nothing. I still do not know what caused the cards to stop providing a charge, but using my motherboard's built in port is now working perfectly. I have a gigabyte aorus master Z490 motherboard.
I would prefer to use an add in card and not stress the motherboard components for this kind of amperage, but apparently there are ways to make it work right depending on your hardware. I do still hope for an update that will make any of the add in cards that can provide the proper amperage draw work again, or at least the discovery of an add in card with better quality components to satisfy our energy hungry headsets.

Just to share, Oculus support have clearly told me that the headset was never designed to charge while connected to a PC via the Link Cable - therefore, none of us should expect it to charge. I can't help but think they are making this stuff up - too bad it did not say this clearly on the box - I would never have purchased the device. Odd that it worked fine for months for me and then stopped after updates.
