Hey all. Anyone knows why charging of the BTR5 stops at random when I plug it to my Pixel 3a with USB?

The BTR5 has charging protection detection. When the output voltage from power supply is below 4.6V the charging will stop.

Thank you for the quick reply. Does that mean that phones in general drop voltage while they charge the BTR5 or just the Pixel?? It doesn't happen all the time... Or does it depend on how much power the phone uses at that time? I mean, if I do something on the phone that draws power, it might drop the voltage of the USB port?
Also, is it a problem in the long run if I charge with a fast 25W PD charger? It gets a little hotter but charges much faster.

A small update about my BTR5 2021 - beside the defective cable it seems that the disconnection issue was driver related - I removed the beta driver and installed the 4.47 and no more issues - already a week since.

Got my Fiio BTR-5 2021 model and it froze and isn't turning on now. I had to force shut it down now it won't turn on. When i try to enter DFU mode , "DFU" appears on the screen for 1 sec and then disappears, but my PC isn't able to recognise the device. I was able to get firmware for 2021 model from fiio support. Can someone help me with what i am doing wrong or what i should do to get my PC recognise it so that i can reflash the firmware?

Didi you install the driver for DFU mode? For the original BTR5 "DPInstall.bat" contained in the firmware package installs the correct driver.

Yes, i did that but nothing happened after runnning DPInstall.bat on my Windows 10 pc, just a window opened and then it closed and then nothing happend. I also double checked that the wire I used and the usb port and they are working properly so I returned the device back to the seller, maybe he can get it fixed or provide me a replacement but frankly i am afraid to get a replacement because a few people on reddit have also been getting the same issue with 2021 model and their device is also not being detected in DFU mode as well.

Sorry it was no help. Just an idea...

Hello guys, I have this weird question: I'm using Tidal HiFi on both my phone and pc! The thing is I played tracks on UAPP using Tidal and connecting through BTR5 and it shows only 44.1 kHz on HD tracks, the same appears on the pc! When I'm not using UAPP and the Tidal app itself it shows 48 kHz but the volume is significantly reduced. Is this normal, am I doing something wrong? Do I need to set something in UAPP/Fiio Control Panel?

Dear friend,

Do you mean the MQA file or which audio quality are you selecting in the Tidal app?
Did you disable the 'Loudness normalization' in th Tidal app? As for in the computer, you would need to switch passthrough MQA function to off as well.

Best regards

So sorry about that. We have reported to the engineer to check about that. Currently, this issue could not be solved by yourself. You may need to contact the seller for replacement.
And if you are convenient, could you please inform us are there any certain operation before this issue happen? Thanks in advanced!

Yes, the output voltage from the usb port of the mobile phone may drop when it could not charge the BTR5.
The BTR5 does not suppor fast charging. If your PD charger could support 5V 2A output, it could work with the BTR5 as well.

This issue arised while I was listening to audio on LG CX tv via Bluetooth and wanted to change the EQ settings so I connected to iPhone 11 bluetooth as well but the audio started getting choppy so i turned off iPhone 11 bluetooth and after disconnecting the audio started playing properly from LG CX. Then I saw that the device wasn't responding to button presses (but audio was still playing) so I had to forcibly shut down the device by holding the power button for more than 10 seconds. After that I could never get it to turn on, I see charging bars (when the device is off) and enter DFU mode but can not turn it on, If the device is off and charging and I press the power button for 2 seconds to turn it on, the charging bars get stuck on the display and nothing happens. After that i have to forcibly shut it down by holding the power button for more than 10 seconds.

Yes I think I figured it out There was an option for MQA within UAPP itself, it's a paid option but its worth it, now I get it to work through btr5 with no issues.As for the PC yes I did disable passthrough MQA and loudness
