This is a most excellent place for technology news and articles.
The manufacturers website lists a 1200mAh 3.8v LiPo battery with a runtime of 8-10hrs BAL, 10-12hrs PO if using wired headphones, and 6-8hrs if using wireless
I'm not actually sure what BAL and PO means
"Balanced output" and "Phone output"? Like the former for when using the 4.4 mm balanced connector and the latter for when using the standard 3.5 mm one... I guess.
8h with wireless doesn't sound too bad at that size. I would hope it to support the ldac codec, but wouldn't bet.
