I just received my UTWS5 few days ago, test running it I find that the left unit drains the battery way faster than the right unit.
It brings the total time to about 4 hours of usage before the left unit is totally drained both started from 100%.
The volume used is on the lower side.
I've tested this on the PC and the phone.

Do I have a faulty pair?
Dear friend,

Please try to fully charge both units of the UTWS5 , then test it again. Does the issue still remain?

Best regards

Thank you for clearing this us folks! 'Compatible' can be (and is often used) quite unspecific.
I think what they're saying is that a source device with AptX HD can still work with an AptX Adaptive headset. Not that the bitrate will be equivalent with the HD codec.

I've tested this myself. Using the UTWS5 with a phone that only supports AptX and AptX HD results in AptX quality as a fallback. Not AptX HD quality. I need to use an AptX HD TWS or my AptX Adaptive USB dongle to get HD quality.

100% factual it will fall back to standard AptX, no matter if the other device has AptX-HD support it will not be AptX-HD.

Not sure why QUALOCOMM made that claim or just poorly worded but I found out the hard and it took feedback from Moto/Lenovo staff to prove to me I would not get AptX-HD on my phone with a set of AptX Adaptive earbuds and it has been posted on this forum dozens of times by others also.

They told me Headphones like the B&W P14's I was using previously have 2 chips (it is a Neckband so plenty of space inside) so they were one of the first to have AptX Adaptive support but also AptX-HD and that is why I thought I had support on my phone.

It's backward compatible in the sense that if your sending device supports AptX adaptive and your receiving device support AptX HD, then you can receive AptX HD. It's not backwards compatible in the other direction, you can't send AptX HD to an AptX adaptive device. So no AptX HD on the UTWS5

here is another test.
4 hours and I hear the battery low on the left unit.
please tell me if I need to contact my local distributor to get a replacement.
I'm not sure if it helps, but my left adapter is also always about 3% ahead of the right. I can't give a technical explanation but I have seen this sort of thing on other TWS buds enough to know it's normal, probably one does a little more coordinating than the other.

As for the 4 hours, I have not really measured mine but I would say I get at least that. I do also have the 1.38 firmware.

I have also seen one side drain before, not so much on these but again, on others. I think it's probably less likely a battery issue rather than one trying and failing to connect ( again, assuming the left one is leader). I've heard reports of these doing a rogue connection to the phone and draining. I have seen mine connect before with the lid closed, but I'm not sure I have again after I updated the firmware.

Hello, may I ask what phone you are using when you connect with UTWS5?

For anyone who bought or was looking to buy the AptX Adaptive USB adapter to go with these earloops (posted in this thread multiple times) I got mine today and bad news is like the 1st Gen Avantree AptX-HD USB Adaptor a couple of years back it is limited to 16/48 so no way can it play AptX-HD or AptX Adaptive with 24 bit files properly , it will simply be just about CD quality.

I cannot find any driver to see if that would bump it up to 24bit, it appears to Windows as a soundcard by "HaisenKeji".

I tested it on my PC with SOUNDPEATS Sonic PRO's and the LED was solid red so AptX Adaptive.
