In balanced it uses both DACs so it should use more power as well... Can you understand differences between balanced and unbalanced?
I will fully charge the device and I will see how long it lasts unbalanced.

After a few more weeks with the BTR5, the battery life just seems to be getting worse and worse. When I connect it via bluethoth, the battery life jumps up by 20%. Around every 30-45 minutes I am losing 20% battery life. Given that this is a portable device, I would say this is not enough for daily use.

I am getting around 6-7 hours in mixed usage connected to PC as a DAC (it doesn't seem to charge in this scenario) and BT. all with 2.5mm out.

I get between 6 and 7 hours when using outside doing yard work, LDAC from phone, 2.5 mm out. Happy with that as it is the only time I use this set up and I have a btr3 backup for the long spring and fall days.

What i can say is:
Once you configured the app, forget about it and just hit the play button. :)

Also true, I honestly can't remember the last time I actually opened the app lol
I agree, I also never really have a reason to open the BTR5 app! But, that is also due, in part, to how relatively useless the BTR5 app is after you have configured the BTR5. The app for the Qudelix 5K on the other hand is infinitely more useful and I do find reasons to open it and play with settings. This is not an X BT receiver is better than Y BT receiver comment, but is a 5K app has more useful functionality than the BTR5 app has comment... :)

I did add some 2nd order harmonics through the app to add a bit more musicality, if you believe in such things. I've stayed with it since without further changes and enjoy the BTR5 immensely with my IEM's.

Hey guys. Can I use BTR5 as a DAC and output to a desktop Amp with a 3.5mm to RCA cable like this?

Should I max the volume then on high gain or?

Hard to tell.

PO on 32ohm is 1.6V and 1.8V (no load).

I'd set it to 55 and have a look how it goes on further increase.

It's not the best way to use the BTR5, i think.
Even my V30 on HIM outputs 2V, which should be a better match for your use case.
Never thought about using the BTR5 as a pre myself. :)

Hey FIIO has a strictly Bluetooth control app - you do not need the bloated cr-app as in the video. Look up FIIO control in the Google app store. I have had no issues with it - with the understanding it is not trying to be a Radsone ES100 app. It does the basics.
