To those using the impedance adapter, why is my phone unable to go to high impedance mode if I connect it through
Short 3.5mm extension cable -> Impedance adapter -> IEM

However when I connect
Impedance adapter -> short 3.5mm extension cable -> IEM ,
then will I be able to go into high impedance mode.

I wanted to connect through the first method as the impedance adapter sticks out quite alot from the jack and using the short 3.5mm extension cable first can help eliminate this issue, as I can bend the short cable.

Am I doing it wrong? How should I connect it? Or I have to live with the protruding impedance adapter?

PS: For the first method, I have tried connecting the 3 together first then plugging it into the headphone jack but still unable to make it to high impedance mode.
For the second method, the moment I plug the impedance adapter first, it automatically goes into high impedance mode, so no issue regardless of the order I insert into the jack.

However , regardless of my previous reply , I hate to tell and confirm to you , it would not work , helps to kicks in the high impedance gain mode IF you're using the cables type of 3.5 extender like the one shown in the pictures below .

The most you can get the the most out with these 3.5 cables extender is AUX mode .
It brings out a output of 25% gain power if I remember correctly what the folks at XDA has concluded with in regards of AUX mode , compared with 50% output gain power in high impedance mode .

From what I had been experiencing from my highly capable 41ohms iem , both mode Aux / high gain are able to push out adequate amount of output to my iem ,
Not only In terms of a noticeable higher volume level , but to a greater listening overall experience , it's really a night and day Huge difference compared to the ridicule low gain normal mode .
So in short , with the exception of the ridicule normal mode , both the AUX mode , high impedance mode are more than enough adequate used for IEM/headphone with the impedance of below 50ohms .


The short right L angle 3.5 adapter also works either in 2 pole or 3 pole .
I still yet to do a direct 1-1 comparison with the 2 impedance adapter of 75ohms , 150 ohms i had at hand , whether or not it does makes any further differences in terms of gain output From the V20 headphone amp sensor . But the words from the XDA folks said that it is of no difference whether you're using a 75 ohms 300 ohms or 600 ohms to trick the V20 sensor .
But somehow I'm still not yet quite convinced on that , mainly because maybe the one whom do the testing doesn't have a number different of ohms adapter to do the comparison ?

Apparently the headphone jack sensor on the V20 does continued to adjust control the sound even though if the device is on high impedance mode , which is shown in screen at HI-FI Quad dac and stated that " sound is automatically adjusted for connected audio device with a high impedance of 50-600 ohms "
???
I don't for one doesn't quite catch the ball what it is trying to say or exactly refer to ???

Any thing which i noticed is , when I use a 2 pole 3.5 extender to kick the high impedance mode , the V20 sensor initially adjust the volume at 40 , while using the 3 pole extender the V20 adjust the volume at 50 .
I will do a direct 1-1 comparison with both the 75ohms , 150ohms to determine whether it's of any differences .

So the right angle adapter will be able to go into high impedance mode but the 3.5mm cable extender is only able to go into AUX mode? I think it is currently happening for me. Only able to go into "external audio" mode. Might have to get the L-shaped adapter and try again.

I think that " sound is automatically adjusted for connected audio device with a high impedance of 50-600 ohms " is to allow the amp to produce enough gain to power the headphones.

I have read in head-fi forums that the members there are stating that there are no technically proven ways that quad DAC only activates in high impedance mode. The quad DAC will activate regardless with just a press of the button.

However I came across a post in reddit that states otherwise.https://www.reddit.com/r/lgv20/comments/62mnbx/how_to_put_v20_in_high_impedance_mode_without_root/

Both head-fi and reddit makes logical sense. Head-fiers states that it does seems strange that the quad DAC will not activate with a low impedance IEM even though turning on the HiFi settings. But the post in reddit, quoted a sentence by LG, also makes logical sense.

Yes correct , the cable type is AUX mode only , confirmed . But both AUX mode , high impedance mode are adequate enough compared to normal mode on my 41ohms iem which I'm using , I'm satisfied with either mode , no problem .
The normal mode just cannot make it .

The L angle ones are the ones you'll need for high impedance mode , I got 2 different types of L angle adapter .
The left one shown on the picture are the best in my user experience , the one on the right was kinda rougher , sort of tightness when plug in on both ends as ( male , female ) sorry can't find suitable words to better describe it , but the left piece has that smoother feel when inserted Both ends .

I bought these at this store , arrived less than 2 weeks , 12 days free shipping .

So does it mean , if a 150 ohms headphone is used , the V20 sensor will produce a set of amount gain power for the 150ohms ?
And when a 300 ohms headphone is being used , the V20 sensor will again produce another set of gain power for the 300 ohms ?
And then when a 600ohms headphone is being used , the V20 sensor again produce yet another different set of gain output for the 600ohms ?
If that's the case and that's what's the sensor thing is designed to do , then I reckoned there would be a huge difference by using different ohms adapter to Trick the V20 into high impedance mode .


That is the main reason why I'm interested to do a direct comparison with various different ohms adapter to see whether or not by using different number ohms adapter to TRICK the Onboard V20 headphone sensor into high impedance mode does really have a effect on how the amp on the V20 produce different gain to output power to the headphones / iem .

Maybe the V20 headphone sensor thing has another set of gain output for powering different headphone with 150 ohms , 300 ohms , 600 ohms .

I mean different set of gain output power for 150 ohms , 300ohms , 600 ohms headphone , rather than a same FIXED set of gain output power for all above 50 ohms headphone .
I did pm the original whom post the trick on XDA , the answer I got from him is it's the same amount of output gain all across for anything above 50 ohms , whether you're using 150 ohm , 300 ohms or 600 ohms , it's the same set of output gain power .

But I suspect it's not the case , as he had only used only a single 75 ohms adapter to put into test , not with numerous of different ohms adapter , so there's no definite just yet , maybe the V20 sensor does further in fact produce different sets of gain output for anything 50 ohms and above , and not a FIXED set of output gain for all 50ohms and above .

I don't know if you can understand what I'm trying to say , but We won't know for sure until we test it out with different ohms adapter .

If there's a noticeable difference in the 75ohms compared to the 150 ohms adapter , it would justify enough for me to bring in the 300ohms , 600ohms to further testing .

I think from 50-600ohms, the gain will be the same. Means might have to increase the volume more for 150ohms and even more for 300ohms. Things might be interesting if its more than 600ohms maybe?

Nevertheless, cant wait for your experiment with the various impedance levels. :D

Ummm , it's something to do with the volume thing , now I get it ,
I will experiment it on my next off day , 75 ohms and 150 ohms adapter .

Hi guys, i have been using this phone for a couple of months with 2 battery swapping around.

Both of my battery SOT average at 3hrs or slightly a few mins more.

However, have been reading around and realise that quite a few users manage reach as high as 6hrs+ for their battery SOT. Does that means my phones have some draining app or do i requires some optimization for the phone?

My SOT is about same as yours 3.5hrs. 9hrs since last plugged and left with 35%.

I see, btw don't mind can share with me ur batt sot?

Sure. But let me do a full discharge cycle first. Because I usually charge my phone once I reach office the next time. Let me do a from 100% - ~10% cycle and screen shot the SOT. :D

Thanks. Hope to see more sot to gauge whether my consumption is normal.

No problem. Do I need to do a full discharge to be accurate?? The default LG battery app will show SOT right??

I think no need for a full discharge. Ur normal day to day charging pattern will be better. Like charge when is low at around 15 to 20% then unplug at 100%.

Yes, default battery app will show sot.
