To my ears there are not only improving in soundstage and details but also instruments separate.

Indeed, I noticed too.
I planned to watch to a movie and I am still stuck with the DX220

If that improvement is sensible, it must be some changes before and after DAC processing?
For those who claims the improvement on SQ, are you all use Mango player? or others.

I am listening to Mango OS. Musics are streaming 320bps online. Will listen to pure Mango tonight to compare.

I'm getting around 8hrs of playback with a stock amp1mk2, 2.5mm balanced output (low gain) playing at normal listening level a mix of mp3/flac files with display off and wifi/BT off, just occasional checking to note the battery level.

I can't understand your stats, really. Im starting to think to send the unit to RMA because it doesn't make any sense to have the half of your battery having the same scenario, really

If you are on mango OS, isn't it "pure mango".

I am only in Mango OS, High Gain with AMP8 and Sennheiser IE800S, battery life is not more than 6 hours.

How about Mango Android? Got confused sometimes.

Hm. Are you sure you are on latest firmware?
Mine DX220 in locked screen mode writes if it is charging in QC mode or normal charging.

It always writes: Charging (X minutes until full)

then, I guess that your charger is not QC or old QC?

My cable is the iBasso cable came with DX220's box, my adapter is Samsung's adaptive fast charging adapter.

This cable+adapter quickcharges my smarpthones but inconsistent to quickcharge my DX220

You did answer your question.
AFC has nothing to do with QC from Qualcomm.

I got the quick charge too, thank you guys for help.

I love this thread, managed to find the solutions of many problems.

Next thing: In addition to the Lurker firmware (which significantly increased the performance), are there other tweaks / applications /modifications you use the improve the UI performance ?

As it was already mentioned, DO NOT use Samsung smartphone chargers with any of your DAPs with QC3.0. It just doesn't work, and with some daps it's 100% no-go (learned it the hard way with N6ii and R6Pro).

Have you tried the full factory reset and start fresh with your test without any new apps, etc? Just do a fresh reset and do battery test first.
