apple lists battery sizes in tech specs on website, confirmed.
ipad weight differences 1.44 lbs vs 1.33 lbs, 8% difference. let me straight: took biggest, heaviest component in ipad , increased capacity 70% bumped weight of device 8%? how'd that? zdnet implies, there must more advanced technology in battery.
wonder charging. charger in both ipad 2 , new ipad 10w per apple's website. new battery take charge faster, or take 70% longer charge device?
it take longer, i'm not sure how much. retina screen, lte (on lte models) , increase in ram contribute higher power consumption, pretty incredible kept +10 hour battery life. worth 60 grams.
