All phones are close to the same dimension, aren’t they?
Why should Apple get special dispensation because - in the same basic form factor - they can only fit a smaller screen and a smaller battery?
The phones are whatever dimensions they choos to make them. Thicker is an option.
The original iPhone battery life was pretty good.
The current phones life sucks !
Apple needs to put bigger batteries in their phones.
There are different models of iPhone which have different sizes of display and, concomitantly, different size batteries. The article indicates that Which? compared a big competing phone with a smaller iPhone, despite the fact that Apple offers a more comparable-sized iPhone.IOW, by design the test disadvantaged the iPhone. In Apple or in other phones you choose the size of the phone as big as you are willing to carry routinely - and as small as your appetite for power allows.
Just reading the article - I don’t own a smart phone.
Are you that mathematics challenged? Space inside increases by the cube of the dimensions. A small increase in the diagonal dimension results in a fairly large increase in space available for battery space. In this instance, it is 11% more volume, which can be dedicated to battery, which means that the battery can be DOUBLED IN SIZE. Pay attention to the engineering, Dan.
Apple chose to put some of their additional miniaturization savings and the space they saved by removing the audio jack into adding a haptic engine. They could have opted to use that space for more battery, but they did not. That was an engineering choice.
Apple is getting no special dispensation. The "form factor" has nothing to do with it, but the volume does. Why does Apple make a 4.7" screen size? because it sells in enormous numbers, far better than any of the three they compared it against. Customers LIKE that size better than they like the larger size.
You ask idiotic questions from little knowledge. . . because the iPhone 7 Plus with the same form factor blows the three other testees away in battery life with the same size screen the largest one of them has, yet has a smaller battery than any of them.
