People state that the iphone 6 plus can last up to 12 hours with moderate use. I usually get around 10 hours of normal use with mine. I have an ipad 4 which I had for almost 2 and a half years and it still gives me around 10 hours of heavy usage which includes mostly Facebook, Watching videos and playing games such as CoC. Given that, I feel that that my ipad has better battery life than my iphone 6 plus. What do you guys think? Shouldn't the Iphone have a much longer battery life than the Ipad 4?
