Same here, got the firmware.. I was worried about update it but I couldn't resist... the system seem ok right now, Battery Capacity is signed as full in battery report. I'll test better tomorrow about battery performance and will report if I notice some problems... but first impression is positive.
Gonna do some tests in the coming days with the battery fault i encountered several times with the bugged december firmware.
Had some weird flaggy screen at start up this seems resolved now, so first impression is good.
