・Battery life: Apple’s solving for x | Six Colors
Meanwhile, if you take a look at the quoted battery life for the iPad, you’ll find that Apple’s definitely solving for 10 hours of battery life. That was the quoted number for the very first iPad, and with some slight variation (occasionally it’s nine!), it’s been so ever since. Apple keeps making the iPad thinner and lighter, with just enough battery to claim 10 hours of life, no more.
So when you’re anticipating the next model of iPhone or iPad, and wondering if it’ll show markedly improved battery life, keep this in mind: So far Apple has behaved as if the battery life of the iPad and the iPhone are perfectly fine as is, and that it would prefer to create a thinner and lighter model to one that puts the makers of external battery packs out of business.
Except for that iPhone 6 Plus. That thing’s a monster.
