Very much doubt thath from my own experience, even with my golds plugged in it lasted around 8,5h in high gain with some albums at 100 volume most at around 92. Mostly around 10 percent an albums some like 15, depending on length. 25% cd Redbook rest various sampling rate 24bit pcm or dsd. For it to consume most in single Album unless he's running akg k1000.Could be use as well. Low efficiency with low impedance phones will accelerate battery drain. Try using pure Mango when viable.
Then perhaps 4h would make sense.
It most definitely is an issue with battery. It may have already gotten fat, with this kind of performance.
I had experience like this when my iBasso dx220 battery was dieing. And even worse on my mom's fiio that she left depleted for a couple of months, last best case 5 min. Even fully charged.
