since FW 2.80 my battery drain goes up to 50% more as before, haven't changed anything on my setup!
before FW 2.80 for 24h arround 7-8%
now with FW 2.80 in 12 hours the same, lost 8%
thanks for the heads-up. well truth is i'm not panicked about this, as i'm pretty sure you guys know that already and sooner or later will come up with a fix :-)
