Suddenly my Bobovr M3 can't keep up with the headset drain

When using my Quest 3, I use a Bobovr M3 headset with a battery. In the past the Bobovr battery would always drain first before the Quest started to drain but now when I use it I get a notice about "slow charging" and the battery can't keep up so the headset actually drains.

Anyone have any idea what has changed? Not sure if it's a BoboVR issue or a Quest 3 issue!

    I had one VR session where it worked fine, then the next week, I had another session where I powered it on with the BoboVR battery connected, got the "slow charging" message, unplugged the BoboVR cable from the power jack and plugged it back in, and then it worked fine and totally drained my battery before draining the headset.

    Same problem with my Bobovr M3 headset battery!

    I have suddenly noticed the exact same thing. The battery on the Bobovr is barely even being drained, and it's mostly coming from the Quest battery. The Bobovr is basically a really good head strap with no battery right now. This has only recently started happening.  I am getting the exact same error that charging is slower than normal as well. It like one of the updates have greatly reduced the charging rate from the Bobovr. Not sure if this was intentional or if it's just a bug. Please let us know if anyone figures it out. I am not back to only getting to play as long as the quest battery can last, which is a huge bummer.

    Yes! Very disappointing. Itโ€™s still a great strap but I need the extra battery life!

    I played tonight and did not get the "slow charging" message and my battery once again drained without my headset draining at all, so hopefully fixed. We will see if it continues.

    Its hit and miss for me. Last night my first battery died so i swapped it out for a fresh one as per normal. When I finished my Q3 was at 33% (had been at 74% when i swapped) and the B2 battery was lit up showing all 4 lights lit as if it was working. Ive had this problem when charging the Q3 whilst off with a battery a few times. Orange light on Q3, bobo lights lit up and on headset showing charging indicator moving but actually not charging. All this since V77

    Started experiencing this exact issue this evening, but I use the S3 Pro strap and model B100 batteries; I think it could be related to PTC v79.

    It's as if the headset battery is draining faster when the battery strap is plugged in. This really needs to be fixed.

    Update: Headset battery dead, now the battery strap is finally charging it while the headset is powered off.
    At least I know Meta wasn't evil enough to push a PTC update that disables battery charging entirely.

    Having the exact problem on my BoBoVR headset. I wrote BoBoVR and got a lot of mumbo jumbo, at least it seemed that may to me. They know about this...

    Hadn't used the Quest 3 for a while. Fired her up tonight and was getting the same issue with the message. I noticed there was a second v78 update as well waiting. Quest battery drained during play like the M3 wasn't even connected. Bloody Meta, can't leave anything alone. Stop buggering things up ffs. If this kind of thing keeps happening then I will more than likely jump ship to another hmd. Until this is fixed you've practically rendered a great accessory useless.

    I really hope they fix this, what I noticed is if you put on your BoBoVR battery after the Quest 3 is already fired up and into the OS, then it seems to work fine. To Charge the internal battery from the BoBoVR, the Quest 3 has to be turned on and in standby mode, then it seems to take a charge from the BoBoVR battery.
    This is a royal pain in the butt, it use to work so well, could fully charge the Quest 3 even when it was turned off and didn't have to jump through hoops to get it to work when being used. I use to insert my BoBoVR battery before turning the Quest 3 on and then fire it up and it worked perfectly.
    Seems they messed up in the firmware starting at V.77, I'm now on V.78 1027 and no fix for the BoBoVR batteries. ๐Ÿคจ

    Yeah the last two times I got the "slow charging" message, unplugging and re-plugging the BoboVR cable fixed it for me.
