What specs will the iPhone 7 have?
Since Apple introduced the company's first branded system-on-a-chip (SoC) in 2010, every new iPhone has come with a new A-series chipset. If Apple sticks to that pattern, the iPhone 7 and iPhone 7 Plus will ship with Apple A10 processors. New SoC typically take advantage of better processes that let them be faster and more powerful but also more energy efficient.
Apple has also been adding coprocessors to handle motion and, now, voice activation, and the A10 could further build on those capabilities as well.
The custom CPUs Apple has been producing have gone from Swift to Cyclone to Typhoon to Twister, so... Tropical Storm next? Hurricane? Rumors also persist that Apple is working on custom GPUs and even modems as well, which would allow the company to take full control of everything from graphics to radios.
While the iPhone 6s and iPhone 6s Plus finally made the jump to 2GB of RAM, frame drop on the iPhone Plus line has led to requests for 3GB of RAM in the larger phones. More recent versions of iOS, though, have fixed the frame drops, so it's unclear how necessary additional memory really is at this point.
Current iPhones also top out at 128GB of storage. Those with large media collections have gotten their hopes up for a 256GB model. Given the space constraints inside the iPhone, the costs of higher density memory, and the lengths Apple has gone to improve efficiencies with app thinning and nearline management, it's also unclear how realistic 256GB would be this year.
Will the iPhone 7 have a 3.5mm headphone jack?
Apple, like almost every major vendor, has considered life after the 100+-year-old headphone jack. It's not much thicker than a Lightning port, but it's an extra hole, it's analog, and it takes up space inside a casing that has precious little of it to spare. This year, though, rumor has it Apple may be serious about finally ditching the 3.5mm headphone jack.
Absent a headset jack, digital audio—potentially higher definition—would be provided via the Lightning port. A pair of Lightning EarBuds would be included in the box, Lightning and Bluetooth headphones would be available from Apple's Beats brand and other vendors, and an adapter with a digital audio converter (DAC) would enable the use of older 3.5mm headphones.
What about an iPad Pro-style Smart Connector?
Apple could certainly engineer a Smart Connector for iPhone 7, but what it would be used for is a more interesting question. Apple made a smaller Smart Keyboard for the 9.7-inch iPad Pro, but would the company make an even smaller one for iPhone 7 Plus? For iPhone 7 standard?
If not a keyboard, then what else would benefit from a not-Lightning, non-Bluetooth connection on an iPhone 7-sized device? Answer that, and you're a long way towards answering whether or not the Smart Connector will be there.
True Tone
Introduced alongside the 9.7-inch iPad Pro in March of 2016, True Tone employs two ambient light sensors, with four channels each, to measure the color temperate of the surrounding area and then match the display to that temperature.
If you've ever seen a picture of an iPhone or iPad where the case looks white but the screen looks yellow or blue, that's what True Tone fixes. And once you get used to it, you want it everywhere.
Again, Apple typically pilots a new technology in a new device, but eventually rolls it out across the line. Here's hoping the same holds true with True Tone and we get the incredible calibration and dynamic compensation on iPhone 7 as well.
Will the iPhone 7 be waterproof?
The Apple Watch shipped with "splash proofing" that technically protected it from rain, sweat, and other minor exposure to water. Even so, Apple's CEO, Tim Cook, told people he took it in the shower and, since launch, people have even been swimming with it.
Other vendors have released waterproof phones in the past, but they either used nano coatings that may or may not be compatible with Apple's environmental policies, or they used little flaps to protect ports that could break off and ruin the protection.
The iPhone 6s, while officially possessing nothing in the way of water resistance, has held up startlingly well to splashes and even dunks. That's thanks to a new gasket around the edge and silicon seals inside.
There are rumors that the iPhone 7 will take that even further, with official "splash proofing" and perhaps even more.
Although swimming with an iPhone may not be on everyone's wish-list, those whose jobs or pastimes expose them to the elements, and even those who want to do underwater photography at shallow depths would be thrilled by the feature.
What changes can we expect in the iPhone 7 cameras?
Based on some recent acquisition, including smart camera company PrimeSense, speculation is high that Apple is working on taking even the 12 megapixels, 4K video camera in the iPhone 6s to the next level. What that means for the iPhone 7 is uncertain, though rumor has it Apple is aspiring to make the iPhone camera as good as a DSLR. That includes better low light, dynamic focus and depth of field, and potentially more.
The potentially more part is currently rumored to include two lenses allowing for even more advanced image signal processing. Whether, like optical image stabilization (OIS), that would be limited to the bigger, slightly more expensive Plus model is unknown.
The second lens could be used for wide-angle shots, to add extra data for better shots, or to pull black and white information for clearer, better low-light photography.
Will the iPhone 7 have wireless charging?
Up until mid-2015, it hadn't been possible to do wireless charging—also known as inductive charging—on a phone with a metal back. Since Apple switched from the glass of the iPhone 4 and iPhone 4s to the aluminum of the iPhone 5 and later models, that effectively meant the company couldn't offer wireless charging as well.
Now methods for induction through metal are being introduced, which means it's possible Apple could keep the aluminum back and offer wireless charging. The iPhone 7 is the first iPhone Apple could launch with the feature if the company chooses to.
If Apple is serious about removing the 3.5mm headphone jack, wireless charging would be a way to let customers listen via Lightning while charging via inductive magnet.
Recent rumors have also suggested Apple is working on resonant inductive coupling, which would let devices charge even at a distance. (The greater the distance, the lower the efficiency.) Such technology is likely a year or more away, though.
What about iPad Pro style speakers?
iPad Pro has four speakers, two on each side. They're loud and clear. iPhone, to date, has only had one. Hold it wrong, and no sound for you. While iPhone 7 almost certainly won't have space inside for the large speaker chambers the iPads Pro enjoy, there have been rumors it might get the same number of speakers. That way you could hold it in any orientation, and in any position, and still hear everything.
