Apple iPhone 7 vs iPhone 6s: Should you upgrade?

Here's why you might (or might not) want to hold off

It's that time again: the dawning of September means Apple has just unveiled a new iPhone, and the iPhone 7 is just over a week away from landing in the hands of millions.

Question is, should it end up in your hands if you're currently wielding an iPhone 6s? The temptation to upgrade can be tempting, especially as this is the thinnest, sleekest Apple phone to date, but are the enhancements really enough to make you jettison a year-old flagship?

We're only working from specs so far, but based on what we've seen, here's our early recommendation.

Yes! Sleek and waterproof

At a glance, the iPhone 7 doesn't bring dramatic changes over the iPhone 6s, which itself was nearly identical to the iPhone 6. Apple's usual every-other-year cycle for introducing a new shape and fresh curves has been chucked aside, seemingly in anticipation of some big 10-year-anniversary model in 2017.

For now, that means the visual changes are largely minor. The antenna lines have been shifted up and down, respectively, to ride the curves – that makes the back a little nicer-looking. And with new colour options, you might find one that is perfectly suited to you. That glossy Jet Black certainly is eye-catching, although Apple admits that it can scratch easily.

And yes, as all the rumours suggested, the classic 3.5mm headphone port has been eliminated - and the phone isn't even slimmer as a result. Killing the port is a definite negative, even if you get Lightning-connectible earbuds and a 3.5mm-to-Lightning adaptor in the box. At least you'll find stereo speakers on the iPhone 7, and they're 2x louder overall.

There's another significant change that you may never notice without a would-be mishap: the iPhone 7 is IP67-rated waterproof, which means it can take both a splash and a puddle bath without failing. Last year's iPhone 6s had some slight water resistance internally, but this is a big step up.

Furthermore, the old home button has been replaced by a pressure-sensitive one that doesn't move, instead reacting to your touch with a pulse from the Taptic Engine. Less moving parts means less chance of breaking, although this could be an awkward shift for anyone who's been using an iPhone for ages.
