1. Yes, the play/pause and skip track on screen buttons work perfectly on my i5 even on the lock screen, but as a personal preference I use the physical buttons more often.
2. Gain settings (aka low db and high db on the i5 software) are usefull to drive a wide variety of IEMs/Headphones with differences in their nominal impedance measured in Ohms (Ω). The Cayin i5 has a recommended headphone impedance range between 8-300Ω which technically means any IEM/Headphone between that range can be driven with the i5 without any constraint thanks to this gain settings and it will sound the way it is intended. "Technically speaking" of course.

Just to be sure to have understood: the high db setting is then for headphones with high impedance?

Yes Sir!

I was listening as per normal during my daily commute to work and I switched the player off when I reached the office.
9 hours later after I was off work, I tried to turn on the player again and there was no response at all. The re-enabling sequence was similar to yours with the recovery mode and the power plugged in.

Thanks for sharing Kell77. I´ll replicate the two following scenarios in the coming days to replicate this behavior and I´ll share any findings with you guys

 
1. I will play the same DSD128 files I heard the night this issue arised, then I´ll pause one of those DSD files and I´ll leave my Cayin i5 On for 10 or 15 hours straight.
2. I´ll start playing the same DSD128 files I heard the night this issue arised and I´ll leave it playing the rest of the music library. At one point the i5 will end playing music and it will stay On, I´ll check the device 10 and 15 hours later.
 
We´ll see what happens lol. I´ll also share the music settings and general i5 settings.

Today I also experienced a strange event of battery draining: when I turned off the i5 yesterday I was pretty sure that battery charge was above 30%. When I turned it on today, it immediately went off "saying" that the battery was at 0%.

That's weird. Mine never did that.

  I almost suffer a heart attack!! lol. I have been thinking about it for a while and actually I don't know if I turned it off when I went to sleep

I might have left it playing music during the night, but I still don't know how or why the device became unresponsive even when I plugged it to the power source 18 hours later I went to sleep. The aforementioned scenario makes me ask the following question:
 
Which would be the normal behavior of the Cayin i5 if it is left playing music for 4 hours straight, and after that it stays on for an indefinite period of time?
 
I'm tempted to replicate this scenario to see if I can replicate this "abnormal behavior". @kel77 would you elaborate your experience? Did your i5 also became "unresponsive"?The 

The behaviour may vary depending on your idle settings. Anyway I've experienced bugs when using the idle shutdown option. The device turning off automatically after the time set period, even if it wasn't on idle, was the most annoying one. So I'm not using that option at all, which drains the battery if I miss to turn it off. Not a fast drain though, so I'm good. I'm also curious about seeing your results after the scenerio replay...

If you backread long enough, you'll see my numerous comments about this issue.  I put mine in the drawer about more than half charged like around 75%, then check it after a couple of days only to see the battery completely drained.  This DAP needs a working deep sleep function just like in my Opus#1.  I leave it 50% charged, will see it again after some days to be almost at the same level, maybe 3-5% less only.

I don't know if we are referring to the same issue: mine was supposed to be completely turned off, so it seems that some process prevented it from shutting down, even if the screen went off. Otherwise I couldn't explain such a behaviour, unless there is some problem with the correct measurement of the remaining charge.

It's a shame that the new Cayin N3 entry level DAP will have Bluetooth 4.0 with AptX while the i5 got Bluetooth from the stone age.

True, but at least they're learning...

Silver lining!

The i5 community will not be too happy to learn that features missed in i5 will be now available in their entry DAP!

My thought would be if you want those features sell your higher priced dap and fund the lower model

 

[BartSimpson1976]

You think applying that strategy would make me buy a Cayin DAP again?

With this hobby I think one simply has to make the best choice that is available at a given time without freaking out every time a new product comes on the market.
