    Dear friend,
    You could test the battery life refer to our website first:
    https://www.fiio.com/btr3_parameters

    Because of the low precision of Bluetooth electricity meter, it can only indicate the approximate quantity of the battery which can still meet the daily using. Most Bluetooth devices in the market are also with low precision.

    Best regards

    Dear friend,

    There will be 10 frequency bands in the EQ.

    Best regards

    Thanks for replying!

    I understand that bluetooth electricity meters are inaccurate, but this is too much. Battery meter shows over 50% when it´s empty. I´ve never seen a device with a battery meter that inaccurate.

    And what about the short battery life? 6 hours running at 30% volume is not acceptable for a new device rated at 11 hours.

    Could this be fixed by a factory reset?

    I have found my Pixel 3 to be fairly accurate with BT battery % for devices. But it does not update that quickly, I believe it is more the fault of how the devices reports them sevles to the phone, not the phone it self. BT devices are not well programed to transmist such info it seems.

    Battery life for the BRT3 has been ammazing for me. I use it about 2hrs each day. and it goes a week easy. It is using LDAC for me.

    For the record, I did order one of those cases for the BTR3 from Ali EXpress.....and....same thing that happened to my previous ordered from Ali.....tracking shows the item is at "Dispatched, HEBRON,KY 41048" as its last scan, 10 days ago. Nothing ever happens after that scan, never receive it. USPS says they are still waiting for item. Meanwhile, I have ordered things form China and Hong off ebay after I ordered the case from AliExpress, and they come in no more than 9 days from order date. Go those orders fine. but nothing from ALi. Their CS, who barley can type English says I must wait 25 more days before they are willing to consider it "Not received status".

    Thanks, however I'm referring to when connecting over Bluetooth, not as a USB DAC.
    When connected to my computer with Bluetooth, I can't get the BTR3's microphone to work. I'd like to use the BTR3 as a wireless PC headset, if possible, could you please help with that?

    Also, do you know anything about the 55ms audio latency when using the BTR3 as a USB DAC on Windows? Do you know if this is a Windows limitation?

    I had to buy this adapter to get the microphone to work. It also supports APTX HD and APTX Low Latency which is really nice. As far as I know most motherboard's built in Bluetooth modules and third party adapters don't even support APTX at all, forcing you to use the much lower quality SBC codec. So I highly recommend getting this adapter if just to get better sound quality. I think SBC is limited to *up to* 328kbps (with most devices playing at way lower than that).

    This is the adapter:

    Avantree Leaf: https://www.amazon.com/dp/B01G3J1I5M/ref=cm_sw_r_cp_apa_i_QQSpCbWKGWKJX

    Only problem that I'm having is that even WITH Aptx Low Latency I'm still getting like 100ms of latency. Not sure why. It's definitely connecting in Low Latency mode. I have a very high end computer.

    Without Low Latency it feels like it's literally an entire half a second of delay. Very jarring in games. At least Low Latency is usable.

    This is literally the only adapter I could find that supports APTX-LL, unfortunately. I don't know if it's the BTR3 that's the problem or the adapter. The adapter is rated at 40ms delay or lower. It's definitely not reaching that. I wanted to get this setup for VR but with such a delay it's not as awesome as I expected.

    Again, I still highly recommend the adapter if you're looking to use it for decently high fidelity means such as listening to music or watching videos. It's great for that. It's just games that are the problem, really.

    My laptop includes an Intel Bluetooth card that happens to supports the Dell AptX driver, so I have both regular AptX and AptX-LL available (no AptX-HD but w/e).
    I haven't precisely measured AptX-LL's latency, but I ballparked it around 50ms in Stepmania's calibration.
    But yeah, no working BTR3 bluetooth mic on PC with this particular setup.

    edit: with the Avantree Leaf, when you need to use the microphone, how do you enable it?

    Avantree Leaf does not support APTX-HD.

    Dear friend,
    Here is the condition of the battery life testing. You may have a test by yourself.

    If you are using LDAC or APTX Bluetooth code and higher volume, the battery life would be shorter.

    Hmmm, interesting. I was planning on getting a BTR3 for gaming over AptX-LL. Anyone else tested the latency of the BTR3 over AptX-LL?

    Hi all,

    Just got my Btr3 yesterday.

    Really satisfied with the sound, but, I am concerned about connectivity.

    The do experience skipping and crackling of audio when walking and my phone (S9 plus) is in my back pocket...

    Is my BTR faulty, or is this normal?
    My firmware is updated.

    Thanks for the advice!

    Hi @FiiO

    Recently purchased the BTR3, overall very impressed, only issue is that none of the controls work with iTunes on macOS Mojave (Play/Pause, Vol +, Vol -, Next Track, Prev Track), have tested this on 3 different macs, will this ever be fixed? Everything seems to be working fine with other apple applications (Safari etc.)

    Thanks for your help :)

    It is btr3 reception limitation, it is mentioned in early post.
