Apple is rumored to be aiming to make the iPhone 7 nearly as thin as the 6.1mm iPod touch, mainly through the removal of the 3.5mm headphone jack and the implementation of a thinner Lightning port. Eliminating the headphone jack will give Apple more internal space for other components, and Apple will also keep the device slim with the continued use of in-cell panels and TFT-LCD display technology. Apple may replace the headphone jack on the iPhone 7 with a second speaker for stereo audio.

With no headphone jack, wired headphones will connect to the iPhone 7 using its Lightning port and Bluetooth headphones will connect wirelessly. Apple is rumored to be working on Lightning-equipped EarPods to sell alongside the iPhone 7.

An image of a device said to be the iPhone 7 Plus has surfaced depicting a Smart Connector on the back of the shell, suggesting that is another potential feature, but it is not yet clear what it would be used for.

Internal specs for the iPhone 7 aren't yet known, but we can speculate Apple will continue on its path of introducing more powerful, efficient devices that grow thinner with each design iteration. The iPhone 7 and iPhone 7 Plus are expected to include next-generation A10 processors manufactured by TSMC.

There are rumored to be some distinguishing features between the iPhone 7 and the larger-screened iPhone 7 Plus. The iPhone 7 may ship with 2GB RAM, while the iPhone 7 Plus could include 3GB RAM, and there is said to be a different camera system that uses two cameras instead of one.

According to rumors, Apple may be planning to introduce two versions of the iPhone 7 Plus -- one with a single lens like the iPhone 7 and a second with a dual-lens camera system that offers DSLR-like image quality with 2-3x optical zoom and improved performance in low light conditions.

A photo of a device said to be the iPhone 7 Plus surfaced on a Chinese website in March. It features a design that's similar in shape to the iPhone 6s, but without rear antenna bands. It has a protruding, pill-shaped camera enclosure that includes two cameras inside, as is rumored for the larger-screened device, along with a round flash.

It also depicts a Smart Connector on the back of the iPhone, which is an unusual inclusion. There's a Smart Connector on the iPad Pro for connecting accessories, but it is unclear how a similar feature would be used on iPhones.

It is not known if this is a genuine iPhone 7 Plus prototype, a dummy based on iPhone 7 Plus specifications, or a completely fake device, but it's possible this is our first look at Apple's new iPhone design. As September nears, additional rumors will confirm whether or not this is a genuine image.

Images depicting what could potentially be the dual-lens camera component for the iPhone 7 Plus surfaced from multiple sources in the early months of 2016. The part has an "821" number on it, which has been associated with Apple in the past, suggesting it could be a legitimate component.

An image of the battery said to be for the iPhone 7 has surfaced, listing a capacity of 7.04 watt-hours. That's slightly larger than the equivalent battery capacity listed for the iPhone 6s (6.61 watt-hours) and almost identical to the iPhone 6 (7.01 watt-hours). Voltage is not visible on the alleged iPhone 7 battery, so the exact charge capacity is not yet available, but should be similar to the iPhone 6 battery.

We've seen a backlight assembly said to be destined for the iPhone 7, which surfaced in January of 2016. We can't really glean any information about the iPhone 7 from the backlight component, but it is similar in design to the iPhone 6s and 6s Plus backlight assembly with the exception of relocated LCD flex cables and 3D Touch chip. Though the backlight assembly doesn't give us any information about the iPhone 7, it suggests that components are now in production and additional part leaks will follow
