Each new generation of Apple’s iPhone has been an improvement over its predecessor, offering new features and, for the most part, improved design. However, what would you find if you compared the original 2007 iPhone to today’s iPhone 7? Now looking old and dated, back in the day, the first iPhone was considered by some to be the very first smartphone (although from a technical standpoint, is not). It was a huge step up in mobile technology, offering improved functionality, ease of use and multi-touch capabilities.

Every iteration including iPhone 7 and 7 Plus in video

Now that the iPhone 7 and iPhone 7 Plus have been in the hands of consumers for about a week, many are learning what this generation of iPhone has to offer. From early feedback, it does look like both handsets are a hit, with the iPhone 7 Plus edging out the standard model, probably because of its dual-lens camera technology.

Yes, some issues are being reported, such as handset activation, cellular connectivity, and GPS problems, but on the whole, the devices are being accepted as worthy successors to the iPhone 6s and 6s Plus.

Why are the iPhone 7 and 7 Plus doing so well?

Before their release, many blogs, critics and consumers were up in arms about the possible lack of design changes. This made them nervous. They didn’t like the idea of an iPhone 7 with the same design as the 6s. However, what they got is a slightly different design with a whole new interior. Plus, the Space Grey color option is gone; in its place are Jet Black and Matte Black alongside Silver, Gold and Rose Gold.

The iPhone 7 is 40% faster

This latest duo of handsets is much quicker than any Apple handset that ever came before. That’s what Tim Cook said on September 7, but don’t just take his word for it. Here’s the information which proves it.

Is it worth upgrading from an iPhone 6s or 6s Plus? It is if you care about performance. Both iPhone 7 models have the A10 Fusion chip; it’s a four-core 64-bit processor with two high-performance and two high-efficiency cores. This gives the A10 a performance increase which makes it 40% faster than the A9 in the 6s.

Furthermore, if you were to compare with the A8 in the 6 and 6 Plus, the A10 is twice as fast. In fact, Apple says that the new iPhone 7 with its superior CPU is 120x faster than the original iPhone.

Improved graphics

The iPhone 7 comes with a huge leap in graphics capabilities. It’s said that the A10 has a performance, which equates to a 50% improvement compared to the A9 and a huge 3x that of the A8. Compared to the very first iPhone, this equates to a massive 240x its graphics capabilities.

Improvements in battery life

The fact that the iPhone 7 and 7 Plus have more processing power than their predecessors doesn’t mean it’s power-hungry.
The cores within the A10 chip are extremely efficient. Apple says that they use one-fifth the amount of power consumed by earlier models, and this is where the conservation of battery life is affected, thanks to the A10‘s performance controller.

Depending on what load is placed upon the A10, the power controller will determine which cores deal with it. For example, lower-power demanding apps will run on the efficiency-cores and higher-power demand met by the high-performance cores. So even with a more powerful chip, that gives it increased performance in all aspects. Overall, the A10 is considerably more efficient than the A9, using two-thirds the power of it and half the amount used by the A8.

What does this mean in real world terms? If you’re upgrading from the iPhone 6s, you will see an extra two hours of battery life, and if upgrading from the 6s Plus, an additional hour of battery life is provided. All-in-all, they offer the best battery life on an iPhone.
