Can anyone comment on the battery life for the iOS client in comparison to skype? I am a heavy skype user, and it doesn't seem like hipchat has a lot to offer than skype does not. Not to mention the inertia that skype has.

however, I would totally consider it, if i could keep it on my phone all day and not have 10% battery by 2pm.

also, curious, does it do group video chat, ala skype?
