After the release of the iPhone 6s last week, Apple fans are said to be already anticipating the release of the iPhone 7.

If it comes out next year, what can the public really expect from the phone in terms of development and innovations?

The rumored features of the iPhone 7 were compared to the specifications of the iPhone 6s below, to give readers a preview of what is next for Apple iPhones.

1. Display and size

Apple said that the iPhone 6S has a 4.7″ Retina HD display with a 1334×750 resolution. It's biggest plus is the 3D touch technology, which makes it users "do things that were never possible before."

FastCompany explained that this new touch technology "works by using new pressure-sensitive sensors built into the display, combined with the Haptic engine, to provide physical, tactile feedback. This allows users to 'peek' into a content inside of apps."

In a more detailed example, it noted that when a link is sent to users through messages, a force touch on that link will give them a preview of the web page sent.

On the other hand, ValueWalk said that users are now expecting a full HD smartphone in the iPhone 7.

"The next generation iPhone 7 should certainly deliver improved screen resolutions, as Apple looks to update the iPhone range to full HD and quad HD respectively," added the same report.

2. Camera

According to USA Today, the iPhone 6s also comes with a 12-megapixel camera that has better autofocus and 4K video capability.

But Value Walk said that there could still be major improvements on this area, like a "next-generation" camera which could snap photos like a DSLR.

3. Processor

The Apple website detailed that the newest iPhone release comes with an A9 64-bit chip, which has 70 percent faster central processing unit and 90 percent graphics processing unit.

Fans certainly expect that this performance will be further boosted with the coming of the iPhone 7.

4. Price

According to Forbes, the iPhone 6s wil sell for $649 for the 16GB variant, $749 for the 64GB version and $849 for the 128GB when pre-orders begin on Sept 12. Models are expected to be shipped by Sept 25.

There are still no price suggestions for the iPhone 7, but it is expected to sell for almost the same price as the newly released phones.

Aside from the mentioned features, Value Walk noted that Apple could also introduce wireless charging on their next iPhone release, especially with rivals possessing the technology.

Another area to improve on are curved displays, which have reportedly generated positive response from mobile fans.

As for storage, ValueWalk said the built-in memory of the iPhone seems to be lagging behind other mobile developers.

"In all honesty, a 16 GB iPhone is rather out-of-date and redundant in the contemporary technology marketplace. This seems especially so considering that Apple has invested so heavily in music," added the same report.
