Hi Everybody

Today i find out that from 24bit/192kHz on the M15 is running extreme hot and one of the cores of the CPU is always at 100%. Affected are all players starting with the FiiO Music App 3.0.1, UAPP latest Version from today and Poweramp. The worst thing can happen with Poweramp (happen to me today) because the High Res Player is upsampling everything to a given sample rate. If you put there 192kHz or above, your battery is draining from 100% to 20% in 4 hours.
So until this bug is fixed stay at 96kHz.

Best regards,
Marco

For me fiio software and implementation is a bug in itself, it's laughable that a 7490mah battery has lower SOT than a medium to hi-end smartphone costing 50% less, with 3-4-5000 mah and having way more processing power, more consuming hardware, phone feature, camera and all that, with bigger, brighter, higher resolution screens.

Thanks for your opinion but I fail to understand why you would state it here. It appears that you do not have a good opinion of Fiio so I fail to see why you follow this thread other to make disparaging statements.

Thank you. After several days of testing.. i find some background noise even on 3.5mm, and even with iematch. Ara is damn super sensitive. It was almost a perfect sounding in ear for my taste if not for the background noise..

Obviously your ears are better than my, must be the age .

I cannot agree here. With OverEar mode, balanced ( Denon AH-D7200) and in poweramp all to 24bit/96khz upsampling and Volume on 55% the player last 10-11 hours. This is overall verry good even if you use a Display time of 1 hour. The most power goes here to the AMP. and the DAC. No phone is comparable to this.

Is this a setting within the M15 Settings or in Fiio music app

No this is a setting in Poweramp. If you have not much High Res files with 24/192 in your library, the FiiO Player is not that much affected of this. Same for UAPP.
If you prefer usability over sound quality (because Fiio MP and UAPP sound way better than poweramp), you have to set the max up sample frequence in PA to 96khz.

Couldn't agree more..

Is it just me or is there no way to enqueue tracks while listening to the M15? I don’t see a “play next” option at all!!?!!
I don’t want to create a new playlist...
Just play songA then perhaps songT then
songH, etc... (who designed this UI)?
Maybe I need to update my firmware?

Dear user,

The 'play next' fution has not been supported in FiiO Music app yet. We will report to the engineer and assess about that.

Dear user,

My colleague will reply you via email. Please provide the log files to us for check as well.

Question, does the hold switch keep it from going off automatically when you set the auto off inactivity? Mine does not turn off automatically when the hold switch is on.

Dear user,

I failed to reproduce the issue you mentioned. Which auto off are you choosing? And you could provide more settings and logs information to support@fiio.com. We will report to the engineer for checking about that.

Best regards

Yes, obviously the amp consumes most of the power but it is also obvious that there is lots of unnecessary processing going on that also consumes the battery. My one plus 7 pro would last 10 hours while streaming and having display continuously on. And has 4000mah battery, stronger cpu, almost the best screen there is and so on. The fact that some say fiio m15 gets so hot means heavy processing. Mine was getting very hot when I bought, now after updates it is better but not for everyone. This means poor implementation.

Unfortunately this is comparing apples with pears. The FiiO M15 has dual Dual AK4499EQ DACs, each with 4 channels. As long as you present it with low quality Spotify streams, the DACs do not really have to stretch their muscles. Once you present them with high-resolution files, the power consumption of those DACs generously exceeds that of the One Plus 7 Pro DAC. Same goes for the AMP .. The M15 typically is used with headphones that are impossible to drive by a regular phone, simply because they have a higher impedance etc. And the power consumption only goes up if you select a higher gain setting, or use the All to DSD setting .. But you get much much higher quality audio in return .. It's not without reason that for many headphones, the manufacturers recommend that they are driven by a desktop headphone amplifier .. The M15 comes pretty damn close to being able to deliver that same current to a pair of headphones .. And make them sound light-years better than a cellphone. Even though in my case my headphones are relatively easy to drive, the same applies.. My Denon D9200 and B&W P9, both easy to drive, sound way better on my M15 than on any standard phone output ..

As an example that makes much more sense, I compared my old Note 10+ to my FiiO M15, both with the standard FiiO Music app over bluetooth to my Shure Aonic 50, forcing both to use the APTX codec .. That is where you really see a different outcome once you level the playing field. In that test, both devices have exactly the same workload because they largely bypass the internal amp ... And that's where the M15 keeps going for ages, well after the Note 10+ has given up ...

Anybody experiencing frequent crashes with Fiio music app 3.01

 

[golferbrad6664]

No updates about tidal running full mqa on this yet huh? UAPP does it for me but I thoroughly hate the UI of it.
Should we write to Jay-Z?

What is the best tidal version to use.i tried
The playstore one and the latest ones on apkpure but they dont play all the mqa files. I used the one from the fiio app store but its ancient and doesn't unfold mqa files 8x. Is there any tidal version that lets fiio m series do a complete unfold 8x?

It crashed for me every time I used it. I tried installing both from the Google Play Store and the .apk download. Same results. I've rolled back to the old version and stayed with it.

I received the mail and answered with the logfile. Today I had a chance to check another M15 (FW 1.0.3). The problem is reproducible with every file above 24bit/96kHz.
Regarding the logfiles looks like a problem with the samsung ALSA implementation.
