iPad 4 has shorter Batt Life than iPad 3? Is this true? thought A6 was more efficient and powerful. Link below. It's an ipad mini review but look @ the 3rd table down where it lists battery life. https://www.macworld.com/article/20...ves-you-most-of-an-ipad-at-half-the-size.html Yes they prob only tested one model or at least had a very small sample size which is why I am asking here.
