Is this battery use normal

-

i have 2014 11-inch haswell macbook air i5 1.4 / 8 gb / 128 gb.

had since october, 3rd mba.

clean install of yosemite. virtually no apps installed. no flash.

if have bluetooth off , brightness 2/3 might scrap 6 hours of battery use. not using the web. i'm typically using nisus or basic text editor (bbedit)

browsing web, on text based sites, no flash, adblock on, 5 or 6 tabs 4.5 hours.

watching film 2.5 hours.

if leave computer on nothing open, , go sleep disabled, lasts 7 hours.

it's not yosemite. getting same on mavericks. know people 12 hours or on 11-inch haswell wifi off, , writing on text editor.

took apple shop, nothing showed on battery test, did clean install in case of runaway process (ironically, have runaway process giving me 2 hours battery life total, that's on thread)
