Everything we know about the iPhone 7 so far

We won't know exactly what Apple has in store for its next iPhone until September.
Even though that is still a few months away, various leaks and notes from analysts have painted a picture of what we might be able to expect from the successor to the iPhone 6 and 6 Plus.
Based on what we have heard, it sounds as if the changes will focus more on enhancing features such as the camera than on redesigning the phone's appearance.

A concept of the iPhone 7 (not associated with Apple).

It will probably be called the iPhone 7 or iPhone 6S.

The next iPhone may be so significantly different from the iPhone 6 and 6 Plus that Apple could call it the iPhone 7, not the iPhone 6s. At least that's what Ming Chi-Kuo of KGI Securities believes,

which he wrote in a note earlier this month. Other reports, however, have referred to the next iPhone as the iPhone 6s, and many still expect Apple to continue its trend of waiting two years before the giving the iPhone a new number.

It may launch on September 25.

Apple may release its next iPhone on September 25, according to the blog Mobile News, which claims to have obtained an internal staff email sent to employees of the British carrier Vodafone. The email reportedly outlined launch plans for the next iPhone, saying the phone would be released on September 25 with preorders starting September 18.
Apple will almost certainly launch the iPhone 7 in September, as it has done with new iPhones in the past, but there's no telling exactly when. Even if Mobile News' email is legitimate, there's no evidence to prove that Vodafone has any knowledge of Apple's iPhone launch plans.

It may come in two sizes, just like the iPhone 6 and iPhone 6 Plus.

Kuo also believes Apple will stick to the sizes it introduced in September and will offer the next iPhone in 4.7- and 5.5-inch variants. 

The next iPhone may be more durable, too.

Apple may use the same Series 7000 aluminum found on the Apple Watch Sport's casing for its next iPhone, according to Kuo. This is said to be 60% more durable than the aluminum Apple uses for the iPhone 6 and 6 Plus. 

The iPhone 7 may be a bit bigger than the iPhone 6.

Kuo also said he thought the next iPhone would be 0.15 millimeters taller and 0.2 millimeters thicker than the iPhone 6, but it's unclear why. The extra thickness could be due to the new aluminum Apple reportedly plans to use, if Kuo's predictions turn out to be correct.

And there's a chance we'll see a new 4-inch iPhone, too.

The Taiwanese publication Digitimes reports that Apple is planning to release three iPhones: a 4.7-inch phone, a 5.5-inch model, and a new 4-inch iPhone. It's unclear how this 4-inch phone would fit into Apple's iPhone lineup and how it would be branded. Digitimes also has a mixed track record, so this report may be bogus.
The Chinese publication The Economic Daily News also reported that Apple would release a smaller 4-inch version of its next flagship phone.

There might not be a home button on the next iPhone.

The Taiwan-based news source Digitimes reports that Apple is working on a new design for the iPhone that would eliminate the home button. Instead the Touch ID fingerprint sensor would be integrated directly into the phone's screen. 
It's important to be really skeptical about this one — Digitimes has reported a lot of details about coming Apple products in the past that have turned out to be false. 

There could be a pink iPhone this time.

Apple is reportedly testing a new pink color option for iPhones, according to The Wall Street Journal. There is no indication that this will ever come to the market, but if Apple is actually experimenting with a new color, we could see it on the next iPhone. 

The camera may be a lot better. 

One of the more plausible rumors seems to be that the next iPhone's camera will get a big improvement. Blogger John Gruber said he heard that the next iPhone would have the "biggest camera jump ever." Apple also recently acquired the Israel-based camera company LinX for an estimated $20 million, according to The Wall Street Journal. LinX's technology could reduce noise and help the iPhone take clearer photos in low-light conditions, among other improvements, according to an analyst note from Macquarie Research. 

Specifically, Apple may upgrade the sensors on both the front and rear cameras for its next iPhone.

Kuo also believes the next iPhone will come with a 12-megapixel main camera, which would be a significant step up from the iPhone's 8-megapixel camera. But there's more compelling evidence about Apple's future plans for the iPhone's camera hidden within the code for iOS 9. Developer Hazma Sood discovered code that suggests the front-facing camera on the next iPhone will support 1080p video capture, 24-frames-per-second slow-motion shooting, a panoramic mode, and a flash.

 

You may be able to add 3D effects to photos.

In fact, LinX's technology may even allow you to add 3D effects to photos taken with the iPhone, according to the note from Macquarie. Specifically, the note says it could enable "3D object modeling" and that the next iPhone could come with a "duo camera." This essentially means the phone would come with more than one camera sensor so it could capture depth-of-field images. This sounds a lot like the camera on the HTC One M8.

 

We may see the same Force Touch technology Apple put into the Apple Watch.

The next iPhone will come with Apple's Force Touch technology that made its debut in the new MacBook and Apple Watch, according to KGI Securities analyst Ming-Chi Kuo. The Force Touch technology in the so-called iPhone 7 will be different from what is in Apple's other recent products, Kuo said. He doesn't think it will detect pressure as the sensor in the new MacBook's trackpad does, but rather it will sense "contact area on which the finger touches the screen to decide how big the pressure is."

And you'll be able to use this Force Touch technology to trigger new features in iOS.

It sounds as if the Force Touch screen will allow for various shortcuts in iOS, according to 9to5Mac's Mark Gurman, who says he spoke with a source who used a prototype from Apple. For example, you'd be able to do things including dropping pins in Apple Maps and scrolling through the iPhone media player by applying more pressure to the screen instead of swiping.

The next iPhone will probably have a better processor.

Apple usually upgrades the processor in its iPhones, so we will most likely see some performance improvements in the next iPhone. We have yet to hear any rumors or insight on exactly what types of enhancements to expect, but Bloomberg reported that Apple chose Samsung over Taiwan Semiconductor to produce its new iPhone chips. 

It'll come with the latest version of Apple's software, iOS 9.

Apple's new iPhones always ship with the latest software, so the iPhone 7 (or iPhone 6s) will come with iOS 9 preinstalled. If you have an older iPhone, you'll also be able to upgrade to iOS 9 when it launches in the fall.
