Hi,
question:- I have ran the battery down and recharged again about 5 times now and it looks stable BUT I have a battery percentage difference between Mango system and Android system? In Mango mode it is showing 50% and in Android it is showing 12%?? Has anyone else seen this?

I expected a small difference but not this much. Its quite repeatable, It just means when I listen with Mango (90% of the time) my DX340 just stop's mid track

I have searched for this on here and Google but there is no definite answer!

Cheers

Mango may calibrate too. Maybe charge to 100% and use until it powers off in Mango OS.

I don't use mango but here is another theory. Im assuming mango has to be its own stand alone OS. Im assuming it also is a stand alone custom android OS and not a different version of linux. If this is true, I would expect that you would need to calibrate both OS. I haven't played around enough to know for sure. If you run the battery all the way down in Mango and plug it back in when you turn it back on does it boot to android or back to Mango? If it boots back to Mango this is what you may need to do. If it boots to android then it would be a moot point. Also my understanding is to calibrate the battery in android correctly you need to run the device all the way down till it force powers off. Then try to turn it back on.
If it comes back on let it go agian till it dies agian. Once it will not boot all the way up leave the unit off and fully charge it. I would just leave it over night. Another thought is that for some reason your reading separate batteries between mango and android. Any of us that had the 320 remember the two different battery guages one for the analog and one for thr digital side. The digital side always died wayyyy sooner than the analog . I never had the analog battery die before. On the 340 they somehow eliminated one of the gauges but still utilized the same dual battery design. Im assuming what we see is the digital battery status based on my experience on the 320. Knowing the analog was pointless in android mode on my 320 maybe you’re reading the digital battery in one and the analogue in another. In my mind mango being just a stand alone OS you may actually run the analog battery down sooner due to the lack of processes running. They may have actually designed it to where in mango stand alone you see the analog battery status due to very little drain on the digital. This would match up to the 320 observation that the analog battery was always way higher then the digital, being based on your comment when you swap to mango your seeing a higher percentage. That being said the mango OS still is running off of the digital side so if your switching over to mango at 13 percent then it would make sense that the player would die mid track. So I believe your either using it differently then most of us which is why your seeing the issue, I try to keep mine in battery bypass by keeping it fully charged and I don't use mango or you possibly have a bad digital side battery or you need to open it up and unplug the battery and replug it in to make sure its connected good. iBasso had me check mine due to some issues with them not being connected good from the factory. If you do this just dont freak out when you try to turn the player back on. It will not turn on till you plug the charger into it. Honestly I believe your just using it differently than most if us, which is perfectly ok its designed to be used this way, and have found a bug. Ill play with mine over the next few days and let you know if I see the same behavior. Honestly if you can fully charge it and get about 6 hours out of it your probity fine. I jump tracks a lot and have the screen on. It drains the battery fast this way vs just turning it on and letting it play.

The battery is bad if while powered off for several days looses charge. I would not try to power back on after it automatically powers off. I only use DC12V IN and digital drains fast but my DAP is heavily tweaked with SOC cores running at MAX most of the time with Stune and schedutil if playing music. This is why I use battery bypass all the time. Mango OS is not android from what I understand. I believe Stouthart has tried to access Mango OS to tweak it.

I use the Ravpower charger with the DX340. USB C To C and no issues. It rapid charges at 9 volts. RP-PC128 90watt, two port. PD charger.

Sometimes I have to unplug the USB from the charger when I initially start the charge and reinsert and then it changes from 5 volts to the 9 volts.

Do you have link to this charger? I wonder if heat could be the issue. With super gain 340 gets hot. Mine would not charge until I powered off and let cool and then it charged fine.

I bought it on Amazon. I don't know if they still have them listed there.

Mine gets warm but not hot but then some call warm hot.Hot is when you can't hold onto something or it is uncomfortable, to me, When every there is dissipation of current, there is heat.

Mine gets pretty hot if I don't open pouch. It's been over 60 C before

Hi,
@mattclarke18 @jstuart83 thank you for you reply's, defiantly somethings I can try
I don't think I use the DX340 any different to others I just charge it up, stick it in my pocket and listen to music (locally) on Mango, I like the sound I get from the Mango player in the dedicated Mango OS.
It only caught me by surprise one day as the music just stopped but the screen was still on (in Mango) and the battery was at 38%. I tried to reboot but nothing. I have the DX320 so used to the odd little hiccup, plugged it into charge and the screen lite up with zero battery. Its charged ok and worked since then but I still have the strange percentage difference between Android and Mango OS. It starts off small say 5% when I check between the two OS systems but as the battery goes down the difference increases to about 40% before the unit shuts down.
I might try and reseat the battery connection....seems the easiest and quickest thing to check. I'm on the second version of firmware that came installed from new, so hoping that is ok....if not I might have to try Matts instructions on firmware updating but I have a crystal clear sound with no static or cracking on AMP15. I use AMP12EXN-S mostly and there is a little noise on there but from what I have read that is expected. It truly sounds amazing though

Thanks to everyone for chipping in and helping

I have the AMP12EXN-S as well and have used it alongside my modded AMP15W.

Overall, AMP12EXN is more fun sounding and I has stronger dynamics than AMP15.
Has engaging 3D soundstage and great macro transients.

However AMP15 has more precise instruments, more accurate and technical soundstage. Even faster transients than AMP12 and more detailed sounding overall.
AMP15W mod adds more warmth and slightly better dynamics with weightier mids.

Comes to show you that the AMP section is probably more important than the DAC when you are talking about dynamics. I can't wait for AMP17 (should be released next month probably) and AMP18.

I hope they're even stronger than AMP15 in battery mode. The DX340 could use a bit more juice in portable mode without Super Gain Mode.

Battery connection likely fine. If not it would go from 100% to 0% just by moving DAP around. Someone sent me a 340 that was missing battery connection clip from factory. I would flash to latest FW and calibration on both mango OS and android. You could check clip on make sure it's present and screw is tight if you have all the torx bits and one small phillips.

Yea you should not have to do that. That is in line with the the behavior I've seen with other chargers they “work” but you should not have to unplug it and replug it in.

I just plugged the charger into the DX340 and it went right to 9 volts. Guess I was wrong. I didn't plug and unplug,

UM has an IEM refurbishment program going on right now until mid June. Andrew at MT has agreed to allow people to ship to MT and they will ship to UM. It does not matter how old your UM IEM is or if its under warranty. They will make it new again for FREE. You just have to pay shipping to MT and about $10 shipping to UM and of course return shipping from MT. I would use Parcel Monkey and email them a label as you will get a discounted UPS rate that way. The more IEMs MT ships tp UM the cheaper it will be. Lets all try and send in by 6-2-25. Please spread the word.

I only use the Mango O/s and the battery reporting is fine. You need to calibrate the battery in Mango O/s

I use the Anker Nano USB-C wall charger [30w]
There are no issues using the USB-C cable and it does rapid charging.
