My brand new iPad2Air was fully charged yesterday. By 11pm it was 70%. By 7am this morning it was 30%. Until the battery died my old iPad 2 would rune for days without use. Have I been shipped a devise with a dud battery?Cheers al let the battery run totally dead to nite and give it a full recharge' if that doesn't work should my warranty not cover it as its only 3 wks old,
