iPhone 2G vs iPhone 6s Plus: The journey so far

30 March 2016 0

In the current age, we have a lot of smartphones around us with many of them capable as much as our PCs and laptops. We can do almost everything from a palm-sized phone in our hand which we used to do solely on the big machines like PCs. While the smartphone power has grown exponentially in past few years, it was the iPhone 2G which started it all. It was the first-ever iPhone and was launched by none other than the tech icon late Steve Jobs.

Ever since its introduction, it is not only the smartphone industry which has grown but, also, the iPhones have grown in a pretty significant manner. The iPhone 2G was announced in 2007 and currently, we have the iPhone 6s Plus as the main Apple iPhone device. As you can see that it has been more than eight years since the launch of the first iPhone, so we decided to compare the first iPhone to the current generation iPhone. Let's see how we have come and how the technology has changed as well as evolved in these eight years.

Let's start this comparison between the iPhone 2G and iPhone 6s Plus with the very first thing that we notice in any smartphone or device for that matter, it is the hardware. The iPhone 2G was launched with a 4.5-inch length, 2.4-inch width, about half an inch of thickness, and 135 grams of weight. On the other hand, the iPhone 6s Plus has a 6.2-inch length, 3-inch width, 0.29-inch thickness, and a weight of 192 grams. As you can see that Apple has not only made iPhones taller and bigger but also lighter.

As for the build, the iPhone 2G was a combination of aluminium and plastic but in the case of the 6s Plus, it is a full aluminium build. This not only makes it sturdier and light-weight but also a lot better in appearance. In the case of the iPhone 2G, the plastic at the lower end used to look like it does not belong here. The only thing is that if you are not a fan of bigger phones, then you will have some issues while holding the iPhone 6s Plus as it is a pretty big phone.

One of the interesting and unique things about the iPhones is that they have only one physical button which is present on the front. While it has remained quite same since the time of the first iPhone, Apple has expanded its usability. Now, it comes integrated with Touch ID which lets you unlock your iPhone by using your fingerprint and without any need of entering your passcode everytime.

On the storage front, the original iPhone was launched in 4GB, 8GB, and 16GB variants. While in current times, the 16GB model is the base model and then you can choose from 64GB and 128GB options. You can see that there has been a pretty impressive growth in the storage section. Can you imagine living with an iPhone with only 4GB of storage now?


The iPhone 2G was launched with a 3.7-inch TFT display with a resolution of 320x480pixels which is about 165ppi. While this falls on the extreme lower end of the display spectrum as per current standards, it was one of the best a smartphone could offer in 2007. If you compare it with the current iPhone 6s Plus, it sports a 5.5-inch IPS LCD FHD (1080p) display with 401ppi. You can feel the difference for yourself.

The size and resolution of the display are not the only things that have changed. Apple has added a few more new functionality to it like the 3D Touch. You can now vary the amount of pressure of your touch on the iPhone display to perform various functions which save your time and get things done faster. It gives you a whole new level of user experience and way of interacting with your favorite apps.


As iPhone 2G was the first-ever iPhone, so it obviously means it ran the first-ever iOS version aka iOS 1. Apple continued to support the software on it till iOS 3.1.3 which was released in February 2010. As for the iPhone 6s Plus, it was launched with iOS 9 and continues to support all the iOS versions which have been released since then.

In the time gap from iOS 1 to current iOS 9.3, Apple has made a lot of changes. The first noticeable change is in the UI and appearance of the app icons. You can see that currently, the UI is a lot flatter, minimalistic, and colorful. In my personal opinion, the initial versions of iOS had app icons which felt kind of realistic while in the modern iOS, they feel more like animated, drawn, and virtual. If you would ask me, I will prefer the older appearance of iOS over the current one on any day.

Apple has also made various performance and productivity based changes to iOS as well. Now, we have a notification center and control center on the iPhone 6s Plus which has become an integral part of the whole user experience on iOS but you might be amazed to know that none of them existed on the original iPhone.

And if that was not enough to surprise you, you will surely get surprised by knowing that there were no App Store and Siri in the first iPhone. Now a days, we all love to install and try out new apps and games as well as talking with Siri and giving her commands for making a web search or to remind us of the things we might forget. Now, imagine an iPhone with no Siri and App Store. Well, that's what was an iPhone 2G for you in those days.

Fun fact: The 'S' in your iPhone 6s Plus stands for Siri ;) (In case, you didn't know)


We all love to capture our best moments and record videos using the iPhone 6s Plus. The camera on the current iPhone is so powerful that it has also been used for making profession short-movies/documentaries and by professional photographers. The iPhone 6s Plus comes with a 12MP rear shooter with f/2.2 aperture, phase detection autofocus, OIS, and dual-tone dual LED flash. You can also record 4k video using your iPhone. As for taking selfies, the iPhone 6s Plus has a 5MP shooter with f/2.2 with the ability to shoot Full HD videos.

On the other hand, the original iPhone came with a 2MP camera which was just good enough to snap a picture. However, don't expect it to get the job done when there are low light conditions. And if you are interested in capturing selfies, I am sorry to disappoint you that you could not do it because there was no front camera on the iPhone 2G. But it should not be a surprise because selfies were not really a trend at that time and moreover, there was no Instagram at that time.

Processor, RAM, and Battery:

The iPhone 2G was powered by a single-core 620MHz chipset underclocked at 412MHz which was coupled with 128MB RAM. While about eight years later, the iPhone 6s Plus boasts of dual-core A9 chipset clocked at 1.84GHz along with a 2GB RAM. You can clearly see the difference and interpret that current generation iPhone is literally a powerhouse in comparison to the original one. It means you would most probably throw the iPhone 2G on a wall if you were asked to do multitasking or browsing on it.

As for the battery, the iPhone 2G came with a 1400mAh battery and the currently iPhone 6s Plus comes with a 2750mAh battery. In both the cases, batteries are non-removable but it's good to see that it has increased the capacity in the time being. However, if you consider the current average usage of an iPhone and the way iPhone 6s Plus is bigger with a high-resolution display, it seems like even 2750mAh is not good enough to last you for a full day.

So, you saw that how much of a growth Apple has done from the first iPhone 2G to the current iPhone 6s Plus. Right from the hardware to software to the overall user experience, iPhones have come a long way. What do you think iPhones will be capable of accomplishing after seven to eight years from today? Share your thoughts with me via the comments section below. I would like to hear them and maybe we can even have a discussion about it.
