Our iPhone 7 report continues, covering iPhone 7 price, iPhone 7 specs, where to buy the iPhone 7, and all the announcements as they happened. Next we'll look at...

iPhone 7 features: Display

iPhone 7 release date, price, specs

While the screen size, resolution and pixel density are the same (4.7 inches, 1334 × 750 pixels and 326 pixels per inch, respectively), there are a number of improvements to the display on the iPhone 7. Apple says it's 25 percent brighter than the previous generation, with a wide colour gamut and improved colour management.

iPhone 7 features: Audio

At one time it was thought that Apple was going to remove the headphone port (we're getting there, we're getting there - it's point number 7, okay?) in order to squeeze in a second speaker at the bottom of the iPhone. Which might have increased the volume output, but wouldn't have produced a stereo effect worth a damn because the speaker units would have been too close together.

What was later rumoured, and has come to pass, is rather cleverer. Apple has upgraded the phone receiver at the top of the device - the one you listen to when talking - into a proper speaker unit with the same power as the one at the bottom of the phone. This means that, when you're not talking on the phone, you can be listening to music, with the device in landscape orientation, in stereo. The two speakers are far enough apart to produce a worthwhile stereo effect. And it's still twice the volume, and (according to Apple), offers increased dynamic range.

iPhone 7 features: EarPods

Or, "7. No headphone port", as most of us will have heard it. Or, "It's not a bug, it's a feature."

So this is the big one. The iPhone 7 does not have a headphone port, and the rumours are true. But Apple did its best to sugar the pill by talking about some legitimately nice-looking and impressive-sounding headphones and headphone tech it's been working on.

The iPhone 7 will be bundled with a new pair of EarPods: these connect via Lightning. It will also be bundled with a Lightning-to-mini phono adaptor, so you'll be able to use any and all current headphones that use a 3.5mm jack, with the iPhone 7. The prospect of carrying around an adaptor with our phones is mildly irritating, but at least Apple isn't charging extra for it, like it did with the USB-C adaptor for the port-poor 12-inch MacBook.

Why is Apple removing the headphone port, by the way? One word, said Apple: courage. (Pretty bold way of dressing up an unpopular move!) But the company argued that Lightning is a good efficient audio connection standard with a large base of users and accessories. (This is slightly disingenuous - there may well be 900 million Lightning connector devices out there, but nearly all of those will be speakers, not headphones. Lightning headphones remain thin on the ground - although that's sure to change now.) The company also said that the headphone port is more than a hundred years old and taking up space that is needed for other features.

Business Insider reported a few days after launch that some iPhone 7 users were experiencing problems with their Lightning headphones. As the headphones rely on software to correctly function now, Apple even went so far as to promise it would be fixed in a software update.

Apple also talked about some interesting wireless headphones it's got up its sleeve, which leads us on to the next section.

iPhone 7 features: Wireless

Apple unveiled a new line of wireless headphones it's working on. They won't be launched alongside the iPhone 7, however: they're coming in late October.

iPhone 7 release date, price, specs: AirPods

Apple's new AirPods are individual wireless headphones, an entirely separate unit for each ear. (Apple suggested that you might like to wear either both together, for listening to music, or just one, for use as a Siri mic.) They're white, and minimalist, and rather beautiful.

And clever. They use infrared sensors to detect when they're in your ear, and only output audio at those times. They're designed to connect to any and all Apple devices with just one tap. And talking of tapping, you can do a double-tap on the headphone itself to activate Siri.

Battery life, Apple says, is good for 5 hours of listening from a single charge.

iPhone 7 features: Apple Pay

Apple Pay is launching in Japan, and the iPhone 7 units sold in Japan will use a different NFC-type tech, called Felica, which is popular in that country. Apple is also launching Apple Maps in Japan.

To be honest this one isn't all that exciting if you don't live in Japan.

iPhone 7 specs: Performance

But here's a bigger one to finish up. The iPhone 7 features an A10 'Fusion' processor, which is 64bit, quad-core for the first time on an iPhone, and has 3.3 billion transistors. Apple claims this is "the most powerful chip ever in a smartphone".

It could be unusually energy-efficient too. Partly because of the usual optimisation Apple is able to achieve between hardware and software, since it makes both. But also because two of the cores in the A10 Fusion chip are designed to use less power - 1/5th of the power, in fact - than the others. This enables the iPhone 7 to run more energy-efficiently when handling less demanding tasks, which can be fobbed off on the lower-power cores, the whole setup organised by an Apple-designed performance controller.

We look forward to trying this out and testing the iPhone 7 in our rigorous lab speed tests. But on paper it sounds great. Apple says the A10 is 40 percent faster than the A9 in the iPhone 6s, and twice as fast as the A8. It's an astounding 120 times faster than the original iPhone (although this is of course a reflection of the breakneck speed of processor development in general as much as it is on the particular abilities of Apple's engineering teams and component partners).

Graphically the A10 appears to be a monster too: Apple reckons its 240 times as fast at graphical processor as the chip in the original iPhone.

These various virtues and abilities add up, according to Apple, to console-level gaming (that'll come in handy when it plays the new Super Mario Run for iPhone, which was also announced at the iPhone 7 launch) and the longest battery life ever on an iPhone: the company reckons you'll get an average of two hours more from the iPhone 7 than you would have got from the iPhone 6s. We look forward to finding out if those things are true.
