Not impressed by need to replace battery on brand new DAP. BTW I bought it from Hongkong eBay seller. Anyway, bad luck, I guess.
It hurts even more when I'm used to get 4 or 5 listening sessions at least 3 hours each without recharge from my old iRiver iHP-140 which has original (11+ years old battery) in it.
Apart from that, sonically DX90 HO is a major improvement, event my Edition 9's like it and they are quite picky with the sources. I'm impressed.
Now just patiently waiting for Rockbox porting (and new JVC HA-FX850 IEM's). The V-Moda XS were OK-ish with iHP, but they don't cut my lower bass mustard on DX90. They will go on sale.
