I'm not saying that. What I am saying is that multitasking puts higher demands on batteries, and if it's not carefully regulated, battery life will suffer needlessly. You have to remember that battery capacity is very much linked to battery size, and many Android phones are much larger than iPhones. You can't simply compare a big phone's big battery to a smaller phone with a smaller battery. You have to compare apples to apples. So compare any given phone's battery life using the Android approach to multitasking to the same phone using the iOS approach to multitasking. With the larger iPhones that are rumored to be coming out, you may see either dramatically increased battery life, or more multitasking, or a combination/compromise between the two.
