In the smartphone world, nine years is a long time. Steve Jobs unveiled the first iPhone on 9th January 2007 at San Francisco's Moscone West. At the time, Nokia was the leading company in the phone industry regarding sales and market share, smartphones with Android OS did not exist, and Blackberry was the top premium phone for consumers. George W. Bush was also the president of the United States in 2007. Crazy ? I know.
At the time, Jobs said, "Today , Apple is going to reinvent the Phone." Looking back, they did. Apple created a product that was easy to use and at the same time more powerful than any other phone in the market. Steve Jobs called it "magical" and "revolutionary." Most people would argue that the first iPhone ushered in the smartphone era. At the moment the ninth installments of the iPhone series, the iPhone 7 and iPhone 7 Plus, have already hit the shelves. Here, we will take a look at how much the iPhone has evolved in certain aspects since its inception. This is a guest post, know about author at the bottom of the article #9YearsofiPhone
Battery Life
There has been an incremental improvement in the battery life of the iPhone over the years. The original iPhone came with a rechargeable 1400mAh Lithium-ion battery. The iPhone 7 has a 1960mAh battery while the larger iPhone 7 Plus has a 2900mAh battery to cater for the increased screen size and higher resolution. Milliamp-hours is not necessarily a measure of energy since the voltage is constant it is a reasonable representative. One consistent measure of battery life in the iPhone 7 is talk time. Compared to the original iPhone's estimated talk time length of eight hours, the current iPhone offers around 21 hours of talk time on 3G.
It is also important to note that the iPhone 7 trails the iPhone 6 Plus models on a couple of measures. These include talk time (21 hours vs 24 hours on the 6s Plus) and less audio playback time on the new variants (60h on the 7 plus and 50h on the iPhone 7 vs 80h on the 6s plus). In the new iPhone 7 models, it seems that Apple optimized battery efficiency for tasks such as browsing. Apple claims that the iPhone 7 has an extra 2 hours under Wi-Fi while the 7 Plus has an extra three hours as compared to their predecessor. The data indicates that Apple handsets have changed dramatically since the days of the iPhone 4 and iPhone 5 although the "non-plus" variants have not had significant leaps spec-wise.
Camera Resolution
In this area, it is important to note that a better resolution does not always mean a batter image. However, increased resolution ensures that you will be able to zoom in on your camera photos without losing quality. The current iPhone has taken a massive leap in camera quality and resolution as compared to the original iPhone. The iPhone 7 has a 12MP camera- a great improvement over the 2MP camera in the iPhone 2G.
The larger iPhone 7 Plus features dual 12MP sensors at the back. One sensor has a wide angle lens while the other has 2X telephoto lens. This combination allows for an effect known as 'bokeh' in photographers. 'Bokeh' is a scenario where there is a sharp focus on the subject and a blurred background in the portrait mode. The iPhone 7 models also excel in low light conditions over the 6s due to an increased aperture (f1.8 vs f2.2 on the 6s), which permits more light to enter the sensor. A smaller f-stop represents a larger aperture.
Storage Capacity
The first iPhone started with 4GB of storage at the lower end and 16GB at the higher end. Fast-forward nine years and the lowest capacity of the iPhone (32GB) is twice that of the higher end original iPhone. Apple has restructured and done away with the 16GB storage option in the ninth-generation models. The least storage option you can get it you opt for the iPhone7/7 Plus models is 32GB of storage. The previous 6s models do not also offer the 16GB option. If you want that option, you can only get it in the iPhone SE models at the moment. Top-of-the-range iPhone7/7 Plus models offer 256GB of storage.
Pixels Per Inch
The Pixels Per Inch represents how crisp the display of a phone is in layman's terms. In the iPhone, these have remained unchanged for the past few generations with most variants offering around 326ppi in the non-plus models while the Plus models have about 401ppi. Looking back nine years ago, this is still pretty impressive considering the models at the time had about 163ppi.
In this area, most Android phone on the market have astounding pixel per inch count with the 5.5 inch Samsung Galaxy S7 edge having around 534ppi while the smaller 5.1 inch Galaxy S7 has 577ppi.
